Part-Time CFO

UK Part-Time CFO Search — Ongoing 2-3 Day Per Week CFO Engagements at Scaling Firms, SMEs and PE-Backed Companies

Exec Capital provides retained Part-Time Chief Financial Officer search across the UK SME, scaling firm, and private equity backed firm community. The Part-Time CFO is a specific senior finance delivery model — typically structured as an ongoing single-employer engagement at 2-3 days per week, with the CFO holding the firm’s senior finance role on a continuing basis but at materially less than full-time hours. Part-Time CFO appointments are common at UK firms that need senior CFO capability — for board interaction, investor reporting, financial strategy, scaling support, transaction readiness — but at sub-£10m through £50m revenue scale where a full-time CFO is not yet warranted by financial complexity or budget. The model is structurally distinct from the Fractional CFO model (multi-client engagement on a day-rate basis serving 2-5 client firms), the Interim CFO model (full-time but time-bound, typically 3-9 month gap-fill or transition assignments), and the broader full-time UK CFO recruitment market.

The UK Part-Time CFO market has grown materially through 2018-2024 as scaling UK firms, particularly in technology, financial services, life sciences, professional services, and the wider UK SME and mid-market community, have recognised that senior CFO capability is essential well before full-time CFO engagement is financially justified. Part-Time CFO appointments typically support firms across critical scaling phases — Series A through Series C funding rounds for venture-backed firms, the £5m-£25m revenue scaling phase for owner-managed UK firms, post-acquisition integration support for PE-backed portfolio companies, IPO preparation in pre-listing phases, and the broader senior finance leadership requirements that define UK firm scaling. Senior Part-Time CFO candidates frequently bring the strategic capability of a full-time CFO at FTSE 250 or major firm level alongside the flexibility to engage on a part-time basis appropriate to the firm’s scale.

The Part-Time CFO Model — How It Differs From Fractional and Interim Arrangements

Understanding the structural distinctions between Part-Time CFO, Fractional CFO, Interim CFO, and full-time CFO models is essential at the brief stage because each model serves materially different firm scenarios and draws from different senior candidate pools.

Part-Time CFO model — the CFO is the firm’s named CFO operating on an ongoing basis at 2-3 days per week (sometimes 3-4 days per week at slightly larger firms). The Part-Time CFO holds the senior CFO role at the firm, attends board meetings as the senior finance representative, owns the firm’s financial strategy and reporting, and accepts personal accountability for the role in the same way as a full-time CFO. The arrangement is structured as ongoing employment or as a continuing services agreement, with materially longer commitment expectations than interim engagements. Compensation is typically structured as pro-rated CFO salary (calibrated against the equivalent full-time CFO compensation at the firm’s scale) plus equity participation where applicable.

Fractional CFO model — the Fractional CFO operates on a day-rate basis serving 2-5 client firms simultaneously, with no single client firm holding the candidate’s senior CFO role exclusively. Fractional CFO engagements are typically delivered through specialist Fractional CFO firms (Pro CFO, FD Centre, the broader Fractional CFO services market) or through independent Fractional CFO practitioners. The arrangement is fundamentally different from Part-Time CFO — the Fractional CFO is the firm’s principal external finance support, but is not the firm’s named CFO. Cross-references with our Fractional CFO recruitment page support firms specifically seeking the Fractional model.

Interim CFO model — the Interim CFO operates full-time on a defined 3-9 month assignment to fill a gap (departing CFO succession, parental leave cover) or support a specific transition (post-acquisition integration, IPO preparation, financial restructuring). The Interim CFO holds the firm’s CFO role for the assignment duration but operates with explicit time-bound engagement rather than ongoing employment. Cross-references with our Interim CFO recruitment page support firms specifically seeking the Interim model.

Full-time CFO model — the standard CFO appointment with the candidate operating full-time as the firm’s senior finance leader, typically structured as full-time employment with the standard compensation framework appropriate to the firm’s scale. Cross-references with our CFO recruitment page support firms seeking full-time CFO appointments.

The model selection matters because role expectations, candidate fit, and offer construction differ across the four models. A senior CFO who has built a portfolio of Part-Time CFO engagements is typically not interested in returning to full-time CFO work; a senior interim CFO operating on consecutive 3-9 month assignments may not be interested in the longer commitment of an ongoing Part-Time arrangement; a senior Fractional CFO operating across 5 client firms may not be willing to reduce to one or two Part-Time engagements. Search engagement design needs to recognise these candidate-pool distinctions.

When UK Firms Use Part-Time CFOs — Five Common Scenarios

UK Part-Time CFO appointments typically arise in five common scenarios. Understanding which scenario applies shapes the senior search engagement design.

Scaling firm progressing from Finance Director to CFO capability

UK firms scaling from £5m-£25m revenue typically reach the point where senior CFO capability is needed for the next phase of scaling — Series A through Series C fundraising for venture-backed firms, professional investor reporting, scaling-stage commercial decisions, M&A scoping, IPO preparation in selected cases, or the broader strategic finance leadership that comes with senior CFO seniority. Part-Time CFO appointments at scaling firms typically support 12-36 months of scaling support before the firm is ready to commit to full-time CFO engagement, with the senior CFO providing strategic capability the firm cannot yet justify on a full-time basis.

SME at owner-managed scale needing senior CFO capability

UK SMEs at the owner-managed £5m-£50m revenue scale frequently use Part-Time CFOs as the firm’s permanent senior finance arrangement — particularly at firms where the founder-CEO or founder-MD prefers to retain operational ownership but needs senior finance leadership for strategic decisions, banking relationships, and board-level financial reporting. Part-Time CFO appointments at owner-managed firms can extend across multi-year periods as the firm’s preferred ongoing arrangement, with the senior CFO becoming a long-term senior team member.

PE-backed portfolio company at lower mid-market scale

Private equity backed portfolio companies at the lower mid-market scale (typically £10m-£75m revenue, £2m-£15m EBITDA) frequently use Part-Time CFO appointments during specific phases of the PE hold period — typically post-acquisition integration support, scaling phase finance leadership, pre-exit preparation, and the broader senior finance dimensions specific to PE-backed firm operations. Cross-references with our wider private equity recruitment practice support senior PE-backed firm appointments.

Pre-IPO firm preparing for full-time CFO appointment

UK firms preparing for IPO frequently use Part-Time CFOs in the early pre-IPO preparation phase before transitioning to full-time CFO appointment closer to the actual IPO process. Part-Time CFO appointments in this scenario provide IPO preparation capability — listing requirements assessment, audit and reporting framework upgrade, investor relations infrastructure development, financial reporting strengthening — at scale appropriate to the pre-IPO firm before the full-time CFO commitment becomes warranted.

Specialist sector firms at niche scale

Specialist UK firms in niche sectors — biotech and life sciences firms in early-stage development, specialist financial services firms at boutique scale, professional services firms at partnership scale, specialist technology firms at sub-£20m revenue — frequently use Part-Time CFOs as the firm’s preferred ongoing arrangement reflecting the firm’s specific scale and structure. At FCA-authorised specialist financial services firms, Part-Time CFO appointments operate under SMF2 with associated regulatory framework application.

The Part-Time CFO Senior Candidate Pool

UK Part-Time CFO senior candidates draw from specific senior career communities. Understanding the candidate pool dynamics is essential for senior search engagement design.

Senior CFOs transitioning to portfolio-of-engagements arrangements — the principal Part-Time CFO candidate pool. Senior CFOs typically transition to Part-Time CFO engagements after 15-25+ years of full-time senior CFO history at scale firms, frequently from FTSE 250, FTSE Small Cap, PE-backed UK firms, or major private firms. These candidates typically operate with one or two Part-Time CFO appointments alongside selected non-executive director or advisory roles, building a portfolio of senior engagements rather than continuing in full-time senior employment.

Senior CFOs returning from international assignment to portfolio arrangements — UK-trained senior CFOs returning from major international assignments (US, Hong Kong, Singapore, Dubai, continental Europe) who choose to build Part-Time CFO portfolios on UK return rather than returning to full-time senior CFO employment. Repatriation candidates typically bring substantial international business knowledge, multi-jurisdictional capability, and the cross-cultural senior leadership capability that supports complex Part-Time CFO scenarios.

Senior Big Four partner-tier candidates with PE-portfolio company experience — senior Big Four partners (PwC, KPMG, Deloitte, EY) with extensive transaction services, PE deal advisory, or audit leadership backgrounds who transition to Part-Time CFO appointments at PE-backed firms or scaling firms post-Big Four career. Big Four background candidates typically bring deep technical capability, M&A experience, and the senior advisory background that supports complex Part-Time CFO scenarios particularly at PE-backed firms.

Senior Finance Directors progressing to senior portfolio CFO roles — senior UK Finance Directors who have built senior careers at FTSE 250 firms or major private firms and progress to Part-Time CFO appointments as the senior career step beyond full-time FD seniority. The progression from senior FD to Part-Time CFO is increasingly common at the senior end of the UK finance leadership market.

Regulatory Framework — SMCR Application at Part-Time CFO Level

UK Part-Time CFO appointments at FCA-authorised firms operate under the Senior Managers and Certification Regime with associated implications for senior appointment processes. Part-time engagement does not reduce the personal regulatory accountability dimensions of the role — the SMF designation operates with the same accountability framework regardless of part-time or full-time engagement structure.

SMF2 — Chief Finance Function — the FCA Senior Manager Function specifically designated for the CFO role at FCA-authorised firms. SMF2 designation carries personal regulatory accountability under SMCR including individual statement of responsibilities documentation, conduct rules application, ongoing fit-and-proper assessment, and personal accountability for the firm’s financial reporting and finance function. SMF2 pre-approval typically takes 4-12 weeks following formal application, with associated due diligence on the candidate’s prior senior regulatory history, conduct record, and fit-and-proper assessment.

SMF3 — Executive Director Function — applies where the Part-Time CFO is also a Board director position. Many Part-Time CFO arrangements at FCA-authorised firms include Board director appointment with associated SMF3 designation alongside SMF2.

Pre-approval and regulatory references — SMF appointments require regulatory references from prior FCA-authorised firms where the candidate has held SMF roles. Senior Part-Time CFO candidates with extensive prior senior CFO history at FCA-authorised firms typically have established regulatory reference history that supports new SMF2 pre-approval applications.

Conduct rules and ongoing accountability — SMF holders operate under the FCA conduct rules with ongoing personal accountability for conduct standards. Part-Time CFO engagement does not modify the conduct rules accountability — the senior individual operates under the same conduct framework as a full-time CFO would. Part-Time CFO candidates therefore need to be comfortable with full personal regulatory accountability for the firm’s finance function despite operating at less than full-time hours.

Compensation Calibration at Part-Time CFO Level

UK Part-Time CFO compensation typically operates on a pro-rated basis calibrated against the equivalent full-time CFO compensation at the firm’s scale. Realistic compensation calibration at the brief stage requires understanding of the firm’s specific scale, industry, and the senior candidate’s full-time-equivalent expectations.

Pro-rated base salary — typical Part-Time CFO base salary operates as a pro-rated portion of the equivalent full-time CFO salary at the firm’s scale. At scaling UK firms (£5m-£25m revenue), full-time CFO equivalent base salary typically operates in the £100,000-£175,000 range, giving a 2-day per week Part-Time CFO base salary in the £40,000-£70,000 range. At PE-backed lower mid-market firms (£25m-£75m revenue), full-time CFO equivalent base salary typically operates in the £150,000-£275,000 range, giving a 2-day per week Part-Time CFO base salary in the £60,000-£110,000 range. At larger UK firms, the full-time-equivalent base salary scales with the firm’s size and complexity.

Day-rate structure as alternative — some Part-Time CFO engagements operate on a day-rate basis rather than salary basis, particularly at firms preferring services agreement structures rather than employment relationships. Typical UK Part-Time CFO day rates operate in the £1,000-£2,000 per day range at scaling firms and £1,500-£3,000+ per day at PE-backed and larger UK firms, with senior Part-Time CFOs at the most senior end commanding day rates above this range.

Equity participation — Part-Time CFO engagements at scaling firms, PE-backed firms, and pre-IPO firms typically include meaningful equity participation alongside cash compensation. Equity arrangements vary materially across firm scenarios — share options, growth shares, restricted equity, performance shares, and (at scaling firms) founder-equivalent equity arrangements all appear in Part-Time CFO compensation packages depending on firm structure. Equity participation frequently dominates total economic value at successful firm exits or IPO transactions.

Bonus arrangements — Part-Time CFO bonus arrangements typically operate on a pro-rated basis aligned with the firm’s bonus framework. Performance criteria typically reflect the firm’s commercial KPIs alongside finance-specific deliverables.

Total economic positioning — strong Part-Time CFO senior candidates building portfolios of 1-2 senior Part-Time engagements alongside non-executive director appointments frequently achieve total economic positioning materially comparable to full-time senior CFO compensation while operating with the flexibility advantages of portfolio-of-engagements arrangements. Senior Part-Time CFOs at the most senior end of the market commonly operate with combined annual economic value exceeding £200,000-£400,000 across two Part-Time CFO appointments plus 2-3 non-executive director appointments.

How Exec Capital Approaches Part-Time CFO Search

UK Part-Time CFO search at Exec Capital follows a retained methodology calibrated to the specific dynamics of senior part-time finance leadership recruitment.

Brief development — initial work focuses on defining the firm’s specific Part-Time CFO requirement (firm scale, sector context, scaling phase or PE-backed context, FCA-authorised firm context where applicable), the specific scenario the appointment supports (scaling phase support, owner-managed firm permanent arrangement, PE-backed firm hold-period support, pre-IPO preparation, specialist sector firm), the days-per-week expectation, the realistic compensation envelope including equity arrangements, and the candidate-fit dimensions specific to the firm’s senior team and Board. Where the brief involves an FCA-authorised firm, we work through the SMF2 pre-approval timeline and regulatory framework dimensions carefully at the brief.

Senior candidate identification — UK Part-Time CFO candidate identification operates across senior CFOs operating with established Part-Time CFO portfolios, senior CFOs transitioning to portfolio-of-engagements arrangements, senior Big Four partner-tier candidates with PE-portfolio firm experience, senior CFOs returning from international assignment to portfolio arrangements, and senior Finance Directors progressing to senior Part-Time CFO seniority. Coverage is structured by sector specialisation and senior career trajectory, ensuring search engagement targets the relevant candidate intersection rather than generalist senior CFO candidates not interested in Part-Time arrangements.

Engagement structure assessment — explicit assessment of the candidate’s preferred engagement structure (employment vs services agreement, days-per-week preference, board director appointment willingness, location and travel arrangement, restrictive covenant compatibility with the candidate’s other portfolio engagements) ensures fit between the firm’s structural preferences and the candidate’s portfolio arrangement.

Regulatory due diligence — at FCA-authorised firms, comprehensive regulatory due diligence covering the candidate’s prior SMF history, regulatory references from previous FCA-authorised firms, fit-and-proper assessment, and any regulatory or conduct issues that could affect SMF2 pre-approval. Pre-approval timeline planning is integrated into the offer construction and start-date arrangement.

Interview process — typically 3-5 rounds for Part-Time CFO appointments, generally compressed compared to full-time CFO process given the experienced senior candidate pool. Interview process typically includes CEO-led senior interview, Board chair engagement, audit committee chair engagement (where applicable), and (at scaling firms) senior investor or PE firm engagement at advanced shortlist stage.

Offer construction and onboarding — Part-Time CFO offer construction typically involves negotiation around days-per-week structure, base salary or day-rate calibration, equity participation arrangements, board director appointment, restrictive covenant compatibility with the candidate’s other portfolio engagements, and the practical onboarding logistics of senior part-time arrangement. Successful offer construction at Part-Time CFO level requires understanding of the candidate’s full portfolio context including other Part-Time engagements, non-executive director appointments, and broader senior career arrangements.
