Part-Time Finance Business Partner Recruitment

Part-Time Finance Business Partner

FD Capital places part-time Finance Business Partners for UK businesses — commercially oriented finance professionals employed on reduced-hours contracts, typically two to three days per week, with full employment rights and exclusive availability to a single employer on their contracted days. The part-time FBP builds the commercial finance partnership relationships that drive genuine influence — attending the same leadership meetings week after week, developing genuine understanding of the business’s commercial context, and becoming the trusted finance voice that operational and commercial leaders actually use when making decisions. Adrian Lawrence FCA, founder of FD Capital and a Fellow of the ICAEW, leads our senior finance recruitment practice.

Part-Time FBP vs Fractional FBP

The distinction is the same one that applies across all FD Capital’s flexible finance engagement types. A part-time Finance Business Partner is an employee — contracted to a single business, working two to three days per week, on salary with holiday entitlement, notice period and full employment rights. They are exclusively available to that business on their contracted days and build the continuity of relationship and institutional knowledge that the FBP role particularly depends on.

A fractional Finance Business Partner works across multiple businesses simultaneously on a day-rate basis. They bring broader cross-sector commercial experience and independence, but divide their working days between clients. IR35 does not apply to an employed part-time arrangement — the individual is on PAYE in the normal way, which simplifies the engagement and removes the IR35 assessment requirement that fractional day-rate arrangements need. See HMRC’s IR35 guidance for the detail.

The practical question is whether the business values exclusive availability and the depth of relationship that comes from employment continuity, or whether it values the broader commercial perspective and day-rate flexibility of the fractional model. For FBP specifically — a role where relationship quality is the primary determinant of influence — the employed model has a stronger case than it does for purely technical finance roles.

What a Part-Time FBP Does on Their Contracted Days

Embedded commercial partnership

A part-time FBP is a member of the business’s commercial team on their contracted days — attending the sales pipeline review, the operational management meeting, the marketing planning session — not as an occasional finance visitor but as the finance representative who is expected to be there. Over time this regular presence transforms the FBP’s role from one of producing analysis that is consumed by commercial colleagues to one of genuinely shaping commercial decisions before they are made. The commercial director calls the FBP before a significant pricing decision, not after the management accounts are published. That shift takes months to achieve and requires the employment continuity that a part-time contract provides.

Commercial performance reporting and analysis

On their contracted days the part-time FBP produces the commercial performance analysis that supplements the management accounts — the revenue bridge that shows what drove the month’s performance, the customer-level profitability analysis that identifies margin dilution, the pipeline analysis that provides the early warning indicators for next quarter’s revenue. This analytical work is more granular and commercially specific than the management accounts the finance team produces, and its value depends entirely on the FBP’s understanding of the business’s commercial model — understanding that deepens over months of employment rather than days of fractional engagement.

Budget and planning process contribution

The part-time FBP contributes to the annual budget process as the commercial teams’ finance representative — working with the sales team to build a revenue plan that is both commercially credible and financially rigorous, supporting the operations leadership in building a cost plan that reflects the planned commercial activity, and providing the CFO with a commercial challenge to the overall budget assumptions that reflects genuine knowledge of the business rather than an external view. This is one of the most valuable contributions a part-time FBP makes — and it requires exactly the kind of deep business knowledge that only comes from being embedded over time.
