Financial Due Diligence: A Complete UK Guide

Financial DD Support: Find CFOs Who Have Led Both Sides of an FDD Process Before

Financial due diligence (FDD) is the detailed investigation of a target business’s financial history, earnings quality, balance sheet, working capital and cash flow that sits at the centre of every UK M&A transaction. It is the workstream that validates or challenges the financial picture presented by a vendor, identifies issues that affect valuation, surfaces risks that need pricing into the deal structure, and gives buyers the evidence base required to commit capital. For buyers, FDD is the primary analytical input into price and deal structure. For sellers, the quality of preparation for FDD — or the quality of their vendor due diligence output — is one of the most influential factors in exit value. For finance leaders on either side of a transaction, FDD is the most intense, most time-compressed, most technically demanding workstream they will ever run outside of a distressed or statutory deadline context.

This guide covers FDD in substantive detail for UK management teams, business owners, finance leaders and advisors. It sits within the wider M&A due diligence framework covered in our M&A Due Diligence guide, which covers the full range of DD workstreams including commercial, legal, tax, operational and technology DD. This guide drills specifically into financial due diligence as a discipline — the scope, methodology, deliverables, UK provider landscape, costs and timelines, preparation requirements, common findings, and the finance leader’s role through the process.

FDD is frequently confused with audit, internal financial review, or general accounting work. It is none of these. FDD is a specific M&A discipline with its own methodology, typical outputs, and professional conventions that have evolved over decades of UK transaction practice. Understanding how FDD works — what providers do and what they do not do, what the reports contain, what findings mean for deal value, and how to engage with the process as a target — materially affects the outcome of a transaction for every party involved.

This guide is part of FD Capital’s broader Knowledge Centre and sits alongside our Preparing for Private Equity, Management Buyouts, and EBITDA guides.

What Financial Due Diligence Is

Financial due diligence is an investigative accounting exercise, commissioned by a party to a transaction, to understand the financial reality of a target business beyond what statutory financial statements disclose. FDD sits below the surface of audited accounts and asks different questions — not “do these accounts comply with accounting standards” (that is audit) but “what is the underlying economic performance of this business, what adjustments are needed to understand it properly, what risks and opportunities exist, and what does the balance sheet actually consist of?”

The core distinction — FDD versus audit

The difference between FDD and audit is fundamental and frequently misunderstood. Statutory audit, performed by a registered auditor to audit standards set by the Financial Reporting Council (FRC), opines on whether the financial statements give a true and fair view in accordance with UK GAAP or IFRS. FDD has no such opinion; it is an investigative and analytical exercise producing a report of findings, not a statement of audit opinion. The FDD team is usually not the company’s auditor; typically the two are explicitly separated to preserve independence.

Why buyers commission FDD

A buyer commissioning FDD is asking a specialist team to answer a set of commercial questions: Is the earnings number presented by the vendor correct and sustainable? What one-off or non-recurring items affect the historical P&L? What is the quality of reported earnings? What is the net debt position at completion? What working capital is required to run the business? Are there any hidden liabilities or off-balance-sheet exposures? How reliable are the vendor’s forecasts? The FDD report gives the buyer evidence-based answers to each of these, which then feed directly into valuation discussions and SPA negotiations.

Why sellers commission FDD

A seller commissioning vendor due diligence (VDD), which is sell-side FDD, is doing the same analysis in advance of a sale process to:

• Identify issues early and address them before they surface in buyer diligence
• Present a pre-prepared information pack to buyers, accelerating the process
• Support the valuation narrative with independent analytical backing
• Reduce the risk of late-stage deal deterioration caused by unexpected findings
• Manage the information flow to multiple bidders consistently

Well-executed VDD often adds more to enterprise value than it costs, particularly in competitive processes where information quality and process credibility affect bidder confidence.

The Scope of Financial Due Diligence

FDD covers a defined set of workstreams that together build a complete picture of the target business’s financial reality. The exact scope of any particular FDD is agreed in the engagement letter with the provider, but the core elements are consistent across UK practice.

Historical performance analysis

The foundation of every FDD is a detailed analysis of the target’s historical financial performance, typically across 3 years of audited accounts plus the most recent management accounts. This analysis examines:

• Revenue analysis by product, customer, geography, channel, and any other relevant cut — seeking to understand the drivers and sustainability of the revenue base
• Gross margin trends and the drivers behind any movements
• Operating cost structure, with particular attention to fixed versus variable costs and the scalability implications
• Historical EBITDA trajectory and the underlying operational reasons for observed trends
• Seasonality, cyclicality, and the sensitivity of earnings to specific commercial or operational drivers
• Comparison of actual performance against budget and forecast to establish management’s forecasting track record

Earnings quality and normalisation

The core output of most FDDs is a normalised EBITDA figure — the headline earnings number adjusted for one-off items, non-recurring costs, owner-related items, and accounting anomalies that distort the comparison between reported and underlying performance. Typical adjustments include:

• Owner-manager remuneration above or below market rates
• Non-business-related expenses run through the P&L
• Restructuring costs, redundancy costs, and one-off legal costs
• Profits or losses on sale of assets
• Bad debt write-offs that are one-off in nature
• Foreign exchange gains or losses that are not part of normal trading
• Accounting policy changes and their effect on comparability
• Non-recurring revenue items (large one-off contracts, rebates, or settlements)
• Expected future cost additions or reductions (new hires planned, office relocations, technology investments)

The normalisation exercise is more art than science. Every adjustment is potentially contentious between buyer and seller because it directly affects the enterprise value, which is typically calculated as a multiple of normalised EBITDA. See our EBITDA guide for detailed coverage of how normalised EBITDA works and the UK convention for adjustments.

Balance sheet analysis

The balance sheet review examines the composition and quality of the target’s assets and liabilities, with specific attention to items that affect the cash-free debt-free enterprise value calculation:

• Net debt: what is classified as debt-like for completion purposes, including financial debt, finance leases, pension deficits, earn-out provisions, contingent consideration, customer deposits, accrued bonuses, deferred tax liabilities and similar items
• Cash: what is truly available versus restricted, trapped, or required for operations
• Provisions: their adequacy, basis for calculation, and any potentially missing provisions
• Intangible assets: impairment risk, amortisation policy, and underlying economic value
• Investments and loans to related parties: terms, recoverability, and treatment at completion
• Contingent liabilities: disclosed and undisclosed

Working capital analysis

Working capital is one of the most commercially sensitive aspects of any FDD because the working capital adjustment at completion directly affects the cash the buyer pays and the seller receives. FDD examines:

• Historical working capital as a percentage of revenue
• Seasonality of working capital (the “working capital cycle”)
• Debtor aging, concentration, and recovery risk
• Inventory turnover, obsolescence provisions, and valuation basis
• Creditor aging and whether payment terms reflect normal trading
• The “normalised” working capital requirement that the buyer can expect to inherit

The normalised working capital level established in FDD typically becomes the “target working capital” in the SPA, with the actual level at completion reconciled against this target to adjust the purchase price.

Cash flow analysis

Cash flow analysis in FDD tracks the conversion of reported EBITDA into actual cash generation through:

• EBITDA to operating cash flow reconciliation, highlighting cash versus earnings differences
• Capex history, distinguishing maintenance capex from growth capex
• Free cash flow generation and its sustainability
• Tax cash flow and its relationship with reported tax charges
• Funding of working capital growth from operating cash versus external sources

A business with strong reported EBITDA but weak cash conversion raises questions the FDD report must answer. See our Cash Flow Forecasting guide for detail on the cash flow disciplines that make a business FDD-ready.

Forecast review

Most FDD also reviews management’s forecast — the budget and the medium-term business plan — for reasonableness, internal consistency, and credibility against historical performance:

• Do the forecast assumptions reconcile to the historical trend?
• Are the forecast growth rates supported by the operational analysis?
• Is the forecast capex level consistent with the forecast revenue growth?
• Are the forecast working capital movements consistent with the revenue profile?
• Does the forecast reflect known future events (contract wins or losses, price changes, cost increases)?

Financial Due Diligence Deliverables

FDD produces a defined set of outputs depending on the engagement scope and the commercial context. The core deliverables in UK FDD practice are:

Full FDD report

The main deliverable of a buy-side FDD engagement. A detailed document, typically 100-300 pages including schedules, covering every workstream described above with findings, analysis, and commentary. The full report is the reference document for the buyer, its deal team, and its advisors during negotiations and SPA drafting. Full FDD reports are structured for senior executive and board consumption with executive summaries, key findings, and detailed supporting analysis.

Quality of Earnings (QoE) report

A focused deliverable, often standalone but sometimes embedded in a full FDD report, that specifically addresses the normalised EBITDA analysis. The QoE report sets out the reported EBITDA, the adjustments applied, the reasoning for each adjustment, and the resulting “adjusted” or “normalised” EBITDA. The QoE report is often the single most important FDD output because it directly determines the deal price. Buyers may commission a QoE-only engagement early in a process as a cheaper and faster validation of the earnings before committing to full FDD.

Red Flag report

A short, early-stage deliverable focused on identifying any deal-critical issues that might kill the transaction. Typically commissioned at the initial assessment phase of a deal, before exclusivity, when the buyer wants rapid insight into whether the target is worth pursuing. Red flag reports focus on the most material issues: earnings quality concerns, balance sheet anomalies, major legal or regulatory exposures, and customer concentration risks.

Trading Update

A short deliverable confirming how the target has traded in the period since the last management accounts were prepared. Used particularly at the completion stage of deals with locked box pricing structures, to confirm that the business has continued trading in line with expectations during the “gap period” between locked box date and completion.

Fact book / data book

A schedule-heavy deliverable containing the detailed financial data underlying the main report — monthly P&L by segment, detailed customer analysis, working capital schedules, debtor listings, and similar detailed exhibits. The fact book is typically used by the buyer’s deal team and post-completion integration team as a reference document.

VDD report (Vendor Due Diligence report)

Structurally similar to a buy-side FDD report but commissioned by the seller. The VDD report is typically distributed to potential buyers at the start of a formal sale process, subject to reliance letters that give the buyer the ability to rely on the report’s findings for their own decision-making. Well-executed VDD reduces process time and cost for both sides, though buyers will typically still commission their own confirmatory due diligence to validate specific aspects of the VDD.

Confirmatory due diligence

A focused engagement commissioned by a buyer to verify specific aspects of a VDD report or the vendor’s data pack, rather than starting from scratch. Substantially cheaper and faster than full buy-side FDD.

Who Performs FDD — The UK Provider Landscape

UK financial due diligence is performed by a well-defined ecosystem of professional service firms spanning Big 4, mid-tier accounting firms, and specialist boutiques. Each tier has different strengths, cost profiles, and typical deal sizes.

Big 4 firms

Deloitte, PwC, KPMG and EY all run substantial transaction services (TS) practices that perform FDD across mid-market and large-cap transactions. The Big 4 dominate the upper mid-market (£200m+ enterprise values) and are almost universally used on large-cap and mega-cap deals. Strengths include depth of sector expertise, global coverage for cross-border deals, and the credibility of the brand for reliance purposes. Typical fee range for a mid-market buy-side FDD: £100k-£250k; large-cap fees substantially higher.

Mid-tier accounting firms

BDO, Grant Thornton, RSM, Mazars and Crowe all run active TS practices competing with Big 4 in the core mid-market (deal sizes £25m-£250m). The mid-tier is often the sweet spot for UK mid-market deals — providing technically strong work at typically 30-50% lower fees than Big 4, with partners who are more directly hands-on with the work. Typical fee range: £50k-£150k.

Specialist corporate finance boutiques

A growing segment of specialist TS boutiques provides FDD in the lower-mid-market (£10m-£75m deal sizes) where Big 4 and mid-tier firms either decline engagement or quote at fee levels uneconomic for smaller deals. Specialist firms combine former Big 4 partners and senior managers with lean operating models to deliver Big 4-standard work at fees often 30-60% lower than mid-tier. Typical fee range: £25k-£75k.

When to use each tier

• Big 4: upper mid-market and above; cross-border deals; deals in regulated sectors requiring specific sector expertise; situations where brand credibility of the report matters (e.g. debt fund lenders specifying Big 4 reliance)
• Mid-tier: core UK mid-market; PE-sponsored deals of £50m-£250m; situations where senior partner involvement is valued over global brand
• Specialist boutiques: lower-mid-market; founder-led transactions; situations where deal economics don’t support Big 4 or mid-tier fees; situations where specific sector expertise is available at the boutique level

Provider selection in practice

Provider selection is typically driven by deal size, sector, buyer preferences, debt-provider requirements (where applicable), and availability. PE sponsors typically have established relationships with one or two preferred providers per tier and will default to those unless there is a specific reason to switch. Management teams should confirm who the sponsor intends to appoint and review the proposed provider before the engagement letter is signed.

Buy-side, Sell-side, Vendor DD and Reverse DD

FDD is packaged and commissioned differently depending on which party is commissioning it and when in the process. The terminology is consistent across UK practice.

Buy-side due diligence

Commissioned by the buyer. Full scope. The FDD report is typically not shared with the seller. Buy-side FDD is the most common model and represents the majority of UK FDD fee volume.

Sell-side due diligence / Vendor due diligence (VDD)

Commissioned by the seller before the sale process starts. The VDD report is shared with bidders subject to reliance letters. VDD is particularly common in PE exit processes and in formal auction sales. Increasingly common in owner-managed business exits given its benefits for process efficiency and value protection.

Reverse due diligence

A less common variant where the target business commissions due diligence on the prospective buyer — checking financial capability, track record of portfolio management, and specific commitments relevant to the transaction. Most common in management buyouts where the management team wants to validate the PE sponsor they are backing for a long-term working relationship.

Confirmatory due diligence

A buyer’s validation exercise on a VDD report, as described above. Substantially cheaper than full buy-side FDD and a common middle ground in competitive sale processes.

The FDD Process — Week by Week

Although every FDD engagement is different, a typical UK mid-market buy-side FDD follows a recognisable timeline, usually 6-10 weeks from kick-off to final report.

Week 1 — Kick-off and information request

The FDD team meets with the buyer and its advisors, scopes the engagement, and issues the initial information request list (“IRL”) to the target. The IRL is typically a 100-200 item list covering financial data, operational data, HR data, commercial data and specific documents. The target uploads documents to the virtual data room as they become available.

Weeks 2-4 — Analytical phase

The FDD team works through the data room, builds analytical models, identifies findings, and formulates follow-up questions. Management meetings happen during this period — typically a day of structured sessions covering each workstream with the relevant target management counterparts. The FDD team produces an initial findings memo or early-stage draft deliverable for the buyer.

Weeks 4-6 — Deep analysis and draft report

The FDD team finalises normalisation adjustments, completes balance sheet and working capital analysis, and produces the first draft of the FDD report. The buyer reviews the draft and provides comments. Follow-up analytical work addresses specific buyer concerns.

Weeks 6-8 — Final report and Q&A

Final FDD report is delivered. The buyer uses the findings in SPA negotiations, which typically run parallel to late-stage FDD. The FDD team remains available for Q&A with the buyer’s legal advisors and, if relevant, with the debt providers who are relying on the report.

Post-completion involvement

The FDD team may continue to support the completion accounts process (in a completion accounts deal structure) or the locked box true-up (in a locked box deal). Post-completion, the FDD team may be engaged to support the integration workstreams for the acquired business.

FDD Costs and Budget Planning

Understanding FDD economics matters because FDD costs typically represent 1-3% of the total transaction cost but can have a 10-20% influence on deal value through the findings they produce.

Typical UK fee ranges

• Lower-mid-market (deal size £10m-£50m): buy-side FDD £40k-£100k; VDD typically similar; red flag only £15k-£40k
• Core mid-market (deal size £50m-£250m): buy-side FDD £75k-£200k; VDD typically slightly higher given the detail required for distribution to bidders
• Upper mid-market (£250m+): FDD £200k-£500k+; large complex deals can run significantly higher
• Large-cap (£1bn+): FDD £500k-£2m+ depending on target complexity and deal structure

Fee structure

Most UK FDD is engaged on a fixed-fee basis with a scope defined in the engagement letter. Out-of-scope work is charged on a time-cost basis. Deal-contingent fees (fees payable only on successful completion) are uncommon for FDD — the provider must be indifferent to the deal outcome to provide objective analysis.

Cost drivers

FDD cost varies with deal size, target complexity, sector, geography, data quality provided by the target, the buyer’s internal capability to carry some of the workload, and the depth of analysis required. Targets with poor-quality management information dramatically increase FDD cost because the provider needs to reconstruct information the target should have ready.

How the Target Business Prepares for FDD

Target preparation for FDD is one of the most influential factors in both the cost of the process and the outcome of the transaction. Businesses that prepare well complete faster processes at lower cost with fewer surprises. Businesses that prepare poorly face extended timelines, higher fees, and findings that reduce deal value.

Information quality

Management accounts should be reliable, consistent, and produced to a standard that a third party can review without substantial reconciliation work. See our Management Accounts guide for the standards expected. Specifically, the target should have ready:

• 3-5 years of monthly management accounts in a consistent format
• Budget and forecast documentation with the underlying assumptions
• Customer, product and geographic sales analysis
• Gross margin analysis by the same cuts
• Detailed trial balance and general ledger extracts
• Working capital and cash flow history
• Debtor aging and credit control records
• Key contracts, supplier agreements, lease agreements, and banking documentation

Normalisation preparation

The target’s CFO should have pre-identified the normalisation adjustments likely to arise in FDD, with supporting evidence for each, so the analysis can proceed faster and with less opportunity for contested adjustments. Vendor due diligence typically produces this as a deliverable, giving the target team a preview of how buy-side FDD will treat the normalisation work.

Data room organisation

The data room should be structured so FDD providers can find what they need without extensive navigation. A well-organised data room has clear folder hierarchies, a logical indexing system, and comprehensive document naming conventions. Many targets benefit from engaging a data room specialist to set up the structure before FDD begins.

Management preparation

Target management should be briefed on what to expect in the FDD management meetings, what topics will be covered, and what level of detail the FDD team will expect. Management teams that have not done an FDD before benefit significantly from rehearsal sessions with their advisors to prepare for the intensity of the questioning.

Pre-FDD cleanup

Many targets benefit from a period of pre-FDD cleanup covering items such as: settling intercompany balances with related parties; resolving stale debtor and creditor items; clearing out dormant subsidiaries; finalising any outstanding tax matters; documenting any informal arrangements; and getting the balance sheet into the cleanest possible form. This work is typically led by the CFO with input from the corporate finance advisor and sometimes from the FDD provider running vendor DD.

Common FDD Findings and Their Impact on Deal Value

FDD findings follow recurring patterns across UK mid-market deals. The common categories — and their typical effect on deal value — include:

Earnings quality findings

Unsubstantiated EBITDA add-backs, over-aggressive normalisation by the seller, or discoveries of non-recurring items not previously disclosed. Impact: direct reduction in enterprise value through the EBITDA multiple (e.g. a £500k reduction in adjusted EBITDA at an 8x multiple is a £4m reduction in enterprise value).

Working capital findings

Historical working capital lower than claimed, seasonality not properly reflected in the normalisation, or specific issues with debtor or inventory quality. Impact: revision of target working capital in the SPA, which directly affects the cash received by the seller at completion.

Debt-like item findings

Items identified by the FDD team as debt-like that the seller had not classified as such — customer deposits, long-term accrued bonuses, earn-out obligations from prior acquisitions, pension deficits, environmental provisions. Impact: reduction in equity value equal to the debt-like items classified.

Forecast credibility findings

FDD analysis that concludes the forecast is over-optimistic, inconsistent with historical trends, or unsupported by commercial evidence. Impact: buyer may reduce the multiple applied to the historical EBITDA, or introduce earn-out structures to share forecast risk.

Customer concentration findings

Discovery that the business has higher customer concentration than previously disclosed, or that specific customer relationships are at risk. Impact: direct reduction in multiple, or specific warranty protection negotiated in the SPA.

Revenue recognition findings

Issues with how the target has recognised revenue — cut-off errors, aggressive recognition of multi-period contracts, or inconsistency in revenue recognition policy. Impact: restatement of historical revenue and potentially EBITDA, reducing the comparator base.

Capex findings

FDD analysis that the business has under-invested in maintenance capex, creating a “capex catch-up” liability for the buyer. Impact: reduction in enterprise value equivalent to the present value of the required catch-up.

Tax findings

Historical tax positions that may not be sustainable under scrutiny, uncertain tax positions, or missing tax provisions. Impact: specific indemnity protection negotiated in the SPA, or direct price reduction if the exposure is quantifiable.

When FDD Findings Kill Deals

Not every FDD finding can be priced into a deal. Some findings kill transactions outright. The patterns are recognisable:

• Material misrepresentation of financial position or performance by the seller, undermining buyer trust in the broader information set
• Systemic financial control weaknesses that call into question the reliability of the reported numbers
• Undisclosed liabilities large enough to significantly affect the deal economics
• Discoveries of potential fraud or financial impropriety, regardless of size, because these change the fundamental counterparty trust
• Regulatory or compliance issues creating material ongoing exposure
• Revenue concentration or customer-specific issues so severe that the business case for the deal collapses

Experienced deal teams identify these risks early — often in the red flag phase — and either adjust terms materially or walk away before committing further resource. The discipline of killing deals where findings warrant it is one of the most important competencies for buy-side teams, and one of the most valuable functions of FDD.

The CFO’s Role in FDD

The CFO or FD is central to every FDD, whether the role is leading the target-side response or commissioning the buy-side work. The specific responsibilities differ by deal position.

Target-side CFO role

• Leading the response to the FDD information request list — ensuring complete, accurate, and timely data provision
• Managing the flow of follow-up questions and analytical requests during the engagement
• Representing the business in FDD management meetings alongside the CEO
• Challenging or clarifying FDD findings before they are finalised in the report
• Working with the corporate finance advisor to translate FDD findings into deal-term implications
• Coordinating with the target’s auditors, tax advisors, and legal team for technical responses
• Post-completion, supporting the completion accounts or locked box true-up process

Buy-side CFO role (on a PE or trade acquirer’s deal team)

• Scoping the FDD engagement with the provider and setting the priority issues
• Reviewing and challenging FDD findings at each phase
• Translating findings into valuation, structural, and SPA term implications
• Supporting the deal team in negotiation by interpreting FDD analysis
• Post-completion, leading the integration of the acquired business’s finance function

The CFO’s technical competence and commercial judgement on FDD matters directly affect transaction outcomes. See our Investor Ready CFO guidance for the specific CFO capabilities required for transaction-intensive environments.

How FD Capital Supports FDD Processes

FD Capital places CFOs, FDs, and specialist finance leaders into UK transaction contexts where the ability to lead FDD — on either the target or buyer side — is a core requirement.

Our FDD-relevant capabilities

• Pre-deal target CFO placements: CFOs placed into target businesses 12-18 months before an intended exit, specifically to prepare the finance function for FDD and lead the VDD process. This is one of the highest-value services we provide. See our Business Exit Preparation and Increasing Business Valuation pages.
• Transaction CFO placements: CFOs placed into target businesses during an active sale process specifically to lead the FDD response and manage the overall transaction from the finance side. Typically interim or fractional engagements. See our Interim CFO and Fractional CFO pages.
• PE portfolio company CFO placements: CFOs placed into PE-backed businesses who will lead FDD responses during the hold period for bolt-on acquisitions and ultimately for exit. See our Private Equity CFO Search and CFO Recruitment for PE-Backed Businesses pages.
• Buy-side deal team CFO support: finance leaders placed into active acquirers running multiple FDD processes simultaneously, particularly in buy-and-build strategies.
• Post-completion integration finance leaders: CFOs and FDs placed into newly acquired businesses to lead the 100-day integration plan, much of which derives directly from FDD findings. See our Transformation CFO/FD page.

Where we add the most value in FDD contexts

The CFOs we place into pre-deal target businesses typically increase exit value by 5-15% through better preparation, cleaner financial records, stronger normalisation support, and more robust handling of the FDD process itself. This is measurable value creation — the difference between a well-prepared FDD and a poorly-prepared one is material to every transaction.

FDD Is a Technical Discipline — Staff Both Sides Accordingly

Financial due diligence is one of the most commercially consequential exercises in any UK M&A transaction. The quality of the FDD provider, the rigour of the target’s preparation, the experience of the CFO on each side, and the integration of FDD findings into the overall transaction all shape the final outcome — whether the deal completes at all, at what price, on what structure, and with what post-completion risks. Buyers and sellers who treat FDD as a tactical box-ticking exercise lose value that better-prepared counterparts capture.

FD Capital places the CFOs and Finance Directors who lead UK businesses through FDD processes from every angle — pre-deal preparation, active transaction management, buy-side support, and post-completion integration. If you are approaching a sale process, contemplating an acquisition, or operating in a transaction-intensive PE-backed environment, the finance leader at the centre of your FDD work is one of the most leveraged appointments you can make. Our Private Equity practice and wider CFO for Fundraising pages cover the full scope of our transaction-focused recruitment work.

A Note from Our Founder — Adrian Lawrence FCA

FDD is one of those disciplines where the difference between a well-run process and a poorly-run one shows up directly in the deal outcome. I have sat on both sides — as a CFO responding to buy-side FDD on businesses I was selling, as an advisor supporting management teams through vendor DD, and across FD Capital’s placement work where we are frequently putting the finance leader into the target business specifically to lead the response to FDD. The pattern is unambiguous: businesses that take FDD seriously as a commercial process, prepare properly, engage credible providers, and staff the response with a finance leader who has been through it before, realise measurably better outcomes than those that treat it as a compliance exercise.

The technical dimensions of FDD matter less than most people think; the commercial and process dimensions matter more. A £50k FDD report identifying £500k of normalisation adjustments the seller had not properly supported translates into a £4m enterprise value reduction at an 8x multiple. A well-prepared target that has its adjustments evidenced and its balance sheet tidied avoids that outcome. The value at stake in getting the finance leader right, on both sides of a transaction, is the order of magnitude that makes specialist recruitment pay for itself many times over.

At FD Capital we place the CFOs, FDs and specialist finance leaders who handle UK M&A and PE transaction work. If you are preparing for a sale, in an active process, or operating in a deal-active environment, I am happy to have a direct conversation about the profile that fits your specific context. Every mandate we take on is handled personally, and transaction-heavy environments are where our recruitment specialism adds the most visible commercial value.
