Understanding the Costs: How Much Does It Cost to Hire a Fractional CFO in London and the Rest of the UK?

The most common question we are asked by business owners considering senior finance support is a simple one: what does a fractional CFO actually cost? This guide sets out current UK rates, how engagements are typically structured, what drives the price up or down, and how the total compares with a full-time appointment.

That range reflects what a business pays for a day of experienced CFO-level input. Where an engagement sits within it depends principally on the seniority and specialism of the individual, the complexity of the business, and the nature of what needs doing — all covered below.

What Drives the Rate

Seniority and track record

The largest single factor. A CFO who has taken a business through a funding round, a sale, an FCA authorisation or a turnaround brings pattern recognition that cannot be acquired quickly, and commands the upper end of the range. A capable finance leader without large-transaction experience sits lower, and for many businesses is entirely the right appointment.

Specialist experience

Particular backgrounds attract a premium because the pool of people who hold them is small — private equity and venture capital experience, FCA-regulated environments, fundraising track records, and complex multi-entity or international group structures. If your requirement genuinely needs one of these, expect the upper part of the range; if it does not, paying for it adds cost without adding value.

Complexity of the business

A single-entity UK business with straightforward revenue recognition and one bank facility requires less than a multi-entity group with international subsidiaries, several funders and covenant obligations. Complexity drives both the rate and the number of days needed.

What the engagement is for

Ongoing finance leadership is priced differently from an intensive, time-bound project. A fundraise, a sale process or a crisis assignment is demanding, deadline-driven and typically requires more days at short notice, which is reflected in the rate.

Days committed

A regular commitment of two or three days a week gives the CFO planning certainty and generally supports a better rate than ad hoc days taken as required. It also produces better results, because the CFO is genuinely embedded rather than visiting.

Location

London engagements typically carry a premium of around 10–20% over regional equivalents, reflecting both the concentration of larger and more complex businesses in the capital and the wider market for senior finance talent there. Remote and hybrid working has narrowed this gap considerably — many fractional CFOs now serve clients nationally, and a regional business is no longer restricted to regional candidates.

How Engagements Are Structured

Regular days on a retainer

The most common arrangement, and generally the most effective. A set number of days each month gives the business predictable cost and gives the CFO continuity. Most engagements run at one to three days per week.

On the day rates above, a monthly commitment works out approximately as follows:

These are indicative figures derived from the day rate. Actual retainers are agreed for the specific engagement and depend on the profile of CFO required and the commitment involved.

Project-based engagements

Where the requirement is defined and time-bound — preparing for a raise, supporting a sale, implementing a new finance system — an engagement can be scoped as a project with an agreed number of days. This suits businesses that need concentrated senior input for a period rather than ongoing leadership.

Interim cover

Where a finance leader has departed unexpectedly or is absent, an interim arrangement provides full-time or near-full-time cover for a defined period. This is a different model from fractional working and is priced accordingly — see our interim CFO page.

How This Compares With a Full-Time CFO

A full-time CFO in the UK typically costs £130,000–£200,000 in base salary, before bonus, employer National Insurance, pension, benefits and recruitment costs. Our CFO salary guide sets out the full picture by company size and sector.

On the rates above, a two-day-per-week fractional arrangement costs roughly £94,000–£176,000 a year. For businesses that genuinely need CFO-level input but not five days of it, the arithmetic generally favours the fractional route — and the comparison understates the case, because the fractional model carries no notice period, no employer NI, no pension, no benefits stack and no long-term commitment.

Where a full-time appointment is the better answer

There is a point at which fractional stops making sense. Where the finance function is large enough to require daily leadership, where the business is undergoing sustained change demanding constant presence, or where the CFO needs to be visibly and permanently part of the executive team — typically above roughly £50m revenue — a permanent appointment is usually right. We will say so if that is our honest view of your situation.

What the Rate Includes

The day rate covers the CFO’s time and FD Capital’s role in sourcing, assessing and supporting the engagement. There is no separate placement fee for fractional arrangements, and no charge for the search itself — you pay for the days worked.

What sits outside the rate: travel and accommodation where an engagement requires significant travel, and any third-party costs such as software licences or specialist advisers, which are agreed in advance.

Is a Fractional CFO the Right Model?

Cost is only part of the decision. A few situations where fractional works particularly well, and some where it does not.

Where it works well

• Growing businesses that have outgrown their bookkeeper or accountant but cannot justify a six-figure permanent hire.
• Businesses preparing for investment or sale, where transaction experience matters more than presence.
• Companies needing specific expertise for a period — an FCA authorisation, a systems implementation, an international expansion.
• Businesses in difficulty needing experienced hands quickly without a permanent commitment.
• Founder-led businesses wanting senior challenge and board credibility without adding a full-time executive.

Where it works less well

• Where the requirement is really operational finance — transaction processing, month-end preparation, credit control. That is a Financial Controller or finance manager requirement, and a CFO is an expensive way to meet it.
• Where the business wants someone available constantly. A fractional CFO works with other clients; if the expectation is daily availability, the model will disappoint.
• Where nobody internally can act between visits. Fractional works best with some finance capability underneath it.

What a Fractional CFO Actually Does for the Money

Rates mean little without knowing what the days are spent on. The work varies by business and stage, but a fractional CFO engagement typically covers some combination of the following.

Board and management reporting

Producing or overhauling the monthly pack so it answers the questions the board actually needs answered, rather than reporting what the accounting system happens to output. For many businesses this alone justifies the engagement, because it is the difference between knowing what happened and understanding why.

Cash flow forecasting and working capital

A rolling forecast the business believes and acts on, plus the working capital discipline that funds growth without further borrowing. Where cash is tight, this becomes the priority and often the reason the CFO was engaged.

Banking and funder relationships

Managing lender relationships, covenant reporting and refinancing. Banks respond differently to a business represented by an experienced CFO than to one where the owner handles it personally, and that difference frequently shows up in terms.

Commercial and pricing input

Understanding profitability by product, customer or contract and acting on it. Pricing is usually the highest-leverage decision available to a business, and the one least often supported by proper analysis.

Fundraising and transactions

Preparing for and executing a raise or a sale — building the model, assembling the data room, handling diligence questions, and standing behind the numbers in front of investors or buyers. This is specialist work and the main reason businesses seek CFOs with transaction backgrounds.

Building the finance team beneath them

A good fractional CFO makes themselves less necessary over time by developing the finance function underneath. That may mean recruiting a Financial Controller, upgrading systems, or coaching an existing team. Engagements often reduce in days as this takes effect, which is the intended outcome rather than a loss of the relationship.

Budgeting Realistically for an Engagement

Expect the first months to be heavier

Most engagements start more intensively than they continue. The CFO needs to understand the business, establish the true position, and usually fix something urgent before settling into a rhythm. Budgeting on the eventual steady-state commitment and being surprised by the initial period is a common error — it is better to plan for a heavier first quarter.

Build in the periods that spike

Year-end, audit, budget season, a refinancing or a transaction all require more days than a normal month. If any of these fall within the engagement, allow for them rather than treating the monthly figure as fixed.

Consider the total cost of the alternative

When comparing against a permanent hire, the salary is only part of it. Employer National Insurance, pension contributions, benefits, recruitment fees, and the cost of a notice period if the appointment does not work all sit on top. The genuine comparison is total employment cost against total fractional cost.

Account for what does not get done otherwise

The harder figure to quantify, and often the largest. Businesses operating without senior finance input tend to carry avoidable costs — poor supplier terms, unexamined pricing, working capital tied up unnecessarily, funding on worse terms than available. A fractional CFO who addresses two or three of these frequently covers the cost of the engagement several times over, though we would be cautious of anyone promising a specific return in advance.

Questions Worth Asking Before You Engage

Whether you work with us or elsewhere, these are the questions that tend to determine whether an engagement succeeds.

Has this person done our specific thing before?

Not senior finance experience generally, but the particular transition you are facing — a first institutional raise, an FCA authorisation, a turnaround, a sale process, a systems migration. Pattern recognition is the main thing you are buying.

How many other clients do they have?

A fractional CFO with several clients has to be honest about capacity. Two or three engagements is normal; considerably more raises reasonable questions about how much attention any one business receives, particularly when something urgent arises.

What happens between visits?

Clarify availability for things that cannot wait for the next scheduled day. Most experienced fractional CFOs are contactable and will deal with something urgent; establishing that expectation at the outset avoids friction later.

What does the exit look like?

A good engagement has a view on what happens next — whether that is reducing days as the finance function matures, handing over to a permanent appointment, or continuing indefinitely. A CFO who has no interest in making themselves less necessary is worth questioning.

Who is actually assessing the candidate?

Many firms present CVs without meaningful assessment. At FD Capital every candidate is interviewed by Adrian Lawrence, a chartered accountant who has held the seat — which is a different exercise from matching keywords on a profile.

Why Rates Vary Between Providers

Businesses comparing quotes frequently find a wide spread and no explanation for it. A few things genuinely drive the difference.

What is actually being supplied

“Fractional CFO” is used loosely. Some providers supply a qualified accountant doing management accounts; others supply a former listed-company CFO. Both may use the same label. The rate difference usually reflects a genuine difference in what you get, so compare the individual rather than the title.

Whether assessment has happened

A cheaper introduction sometimes reflects that nobody has properly assessed the candidate against your requirement. That cost does not disappear — it reappears as your time, or as a poor appointment.

Ongoing support

Some arrangements are a one-off introduction; others include continued involvement if the engagement needs adjusting. Worth establishing which you are buying.

Whether the rate is realistic for the person

A rate materially below the market for the profile described usually means either the profile is overstated or the individual will not sustain the commitment. Both tend to surface within a few months.

Frequently Asked Questions

How much does a fractional CFO cost in the UK?

Typically £900–£1,700 per day, with most engagements settling in the middle of that range. On a regular commitment, one day per week works out at roughly £3,900–£7,400 per month and two days per week at £7,800–£14,700. The rate depends on the seniority and specialism required and the complexity of the business.

Is a fractional CFO cheaper than a full-time one?

For businesses that do not need five days a week, yes — substantially. A full-time CFO costs £130,000–£200,000 in base salary before employer NI, pension, bonus and benefits. Two days a week fractional costs roughly £94,000–£176,000 annually with none of that additional stack, and no notice period or long-term commitment.

Do London rates differ from the rest of the UK?

London engagements typically carry a premium of around 10–20%, reflecting the concentration of larger and more complex businesses and the wider talent market. Remote and hybrid working has narrowed the gap, and regional businesses are no longer limited to regional candidates.

How many days will we actually need?

Most businesses start at one to two days per week. The honest answer depends on what needs doing: ongoing oversight and board reporting can work at one day a week, while a fundraise, a sale process or building a finance function from a weak base needs more. We would rather scope this realistically than agree a number that does not work.

How long do engagements typically last?

Ongoing fractional arrangements frequently run for years, with the commitment adjusting as the business changes. Project engagements are usually three to twelve months. Many businesses start with a defined initial period and continue if it is working.

What is the difference between fractional, part-time and interim?

Fractional means a regular ongoing commitment of one to three days a week, usually alongside other clients. Part-time generally describes an employed arrangement on reduced hours. Interim means full-time or near-full-time cover for a defined period, typically covering a departure or a specific project. See our pages on fractional CFO, part-time CFO and interim CFO for how each works.

How quickly can you introduce candidates?

For most fractional CFO requirements we can present a shortlist within a week. Highly specialist requirements — a particular regulatory background, an unusual sector, a specific transaction type — take longer, and we will say so at the outset rather than delay and disappoint.

What if it is not working?

Fractional engagements have no notice period of the kind a permanent appointment carries, which is part of the point. If the fit is wrong, it can be ended and we will find an alternative. In practice this is uncommon, because the assessment happens before the introduction rather than after.

Rates shown are indicative of the current UK market and correct at the time of writing. Every engagement is quoted individually based on the profile required, the days committed and the complexity of the business.
