Interim CFO

Interim Chief Financial Officer Executive Search

Exec Capital places interim Chief Financial Officers with UK businesses facing financial transition, a sudden CFO departure, a fundraising or transaction event, or a period of growth that has outpaced the existing finance function. An interim CFO steps into the full scope of the CFO role — financial strategy, treasury, reporting, investor relations, and finance team leadership — for a defined period, typically three to nine months, without the timeline and cost of a permanent search.

The CFO function carries responsibilities that cannot be left unled. Audit and reporting obligations continue regardless of whether a permanent CFO is in place. Investor and lender relationships require active senior management. Strategic financial decisions — on capital allocation, M&A, fundraising, and risk — cannot wait. An experienced interim CFO who can step into these responsibilities credibly and quickly is consistently one of the highest-return executive investments a business in transition can make.

For businesses whose primary need is sustained fractional or part-time CFO or Finance Director leadership — rather than a full-time interim appointment — Exec Capital’s sister practice FD Capital specialises in this model and has an active network of fractional CFOs and FDs available across the UK. The ICAEW and the CFA Institute both publish guidance on CFO responsibilities and financial leadership standards that inform how Exec Capital assesses and profiles candidates for CFO mandates.

How It Works: Appointing an Interim CFO Through Exec Capital

Interim CFO appointments are usually made under pressure, so the process is deliberately short on ceremony and long on clarity. Each step exists because skipping it is how interim appointments go wrong. We agree the timetable with you at briefing, because the right pace for a covenant problem is different from the right pace for a planned maternity cover or a pre-sale finance upgrade.

When Businesses Need an Interim CFO

The circumstances that lead a board to appoint an interim CFO fall into a small number of recognisable patterns, each requiring a specific candidate profile.

Sudden or unexpected CFO departure. A CFO departure — whether planned or abrupt — leaves an immediate gap in financial leadership, investor communication, and board-level financial oversight. For businesses with lenders, institutional investors, or audit obligations, this gap is not manageable beyond a few weeks. An interim CFO who can assume the full role from day one — including board reporting, lender relationships, and audit sign-off responsibilities — is the most effective response. The alternative of asking a Financial Controller or Finance Director to act up rarely delivers the same quality of strategic financial leadership.

Fundraising, M&A, or transaction events. Fundraising rounds, trade sales, acquisitions, and management buyouts create peak financial leadership demand that most in-house finance teams cannot absorb alongside their normal responsibilities. An interim CFO with specific transaction experience — who has run data rooms, managed institutional investor due diligence, negotiated financial terms, and managed completion accounts — provides the capability that makes the difference between a well-executed and a poorly-executed transaction. This is the single most valuable application of interim CFO expertise and often the highest-return appointment a business makes in the context of a transaction.

Financial distress or cash flow crisis. When a business faces a liquidity crisis, covenant breach, or creditor pressure, it needs a CFO who has managed exactly these situations before — who can communicate credibly with lenders and creditors, build a short-term cash flow model that stakeholders trust, negotiate breathing room, and implement the financial controls that demonstrate the situation is being managed. This requires direct experience of financial distress at CFO level, not general financial management expertise reframed as turnaround capability. Where the wider leadership team also needs strengthening, our turnaround executive recruitment practice works alongside the CFO search.

Finance function that has not scaled with the business. High-growth businesses frequently reach a point where the financial infrastructure — reporting, controls, systems, treasury management — has not kept pace with operational scale. An interim CFO who can assess and upgrade the finance function, often while simultaneously running the existing operation, creates a platform for sustainable growth. This mandate is particularly common at Series B and growth-equity stage where investor expectations of financial governance increase substantially.

Bridging a permanent CFO search. A thorough permanent CFO search — particularly for a business with a specific sector background, transaction history, or investor profile requirement — takes time, and senior finance executives often have long notice periods to serve before they can start. An interim appointment maintains financial leadership and strategic continuity throughout, and the interim CFO often provides the most valuable input into the permanent brief and candidate assessment.

Regulatory events at FCA-authorised firms. At banks, insurers, investment firms and other FCA-authorised businesses, the CFO seat may be a senior manager function. When the incumbent leaves without warning, the firm needs someone credible in the role immediately and a plan for the approval application. We cover this in more detail below, because the rules changed in 2026.

What an Interim CFO from Exec Capital Will Do

Board and investor financial leadership. Presenting financial performance, forecasts, and strategic financial recommendations to the board, shareholders, and lenders with the clarity and credibility that only a CFO-level professional can provide. In businesses with institutional investors or PE backing, this includes the structured reporting and financial communication that investors expect from a portfolio company finance function. For investor-owned businesses hiring on a permanent basis, see our portfolio company CFO recruitment service.

Financial strategy and planning. Translating the business’s strategic objectives into a coherent financial plan — capital allocation, funding strategy, working capital management, and three to five year financial modelling. The interim CFO who limits their contribution to month-end reporting and cash management is not delivering the value the role offers.

Treasury and cash management. Managing banking relationships, optimising working capital, maintaining covenant compliance, and — in distressed situations — building and presenting the short-term cash flow models that underpin stakeholder confidence. The Association of Corporate Treasurers sets the professional standards for treasury management that inform best practice in this area.

Finance team leadership and assessment. Managing the existing finance team, assessing individual capability, identifying structural gaps, and — where the mandate includes preparing the function for a permanent CFO — ensuring the team is structured and resourced to support the incoming executive. A good interim CFO leaves the finance function stronger than they found it.

Transaction and compliance management. Leading or supporting M&A due diligence, fundraising financial preparation, audit management, statutory compliance, and tax. In transaction contexts, this includes managing the financial workstream of the deal process, coordinating with external advisers, and ensuring financial representations in transaction documents are accurate and defensible.

When to Hire an Interim CFO vs a Fractional, Part-Time or Permanent CFO

The title is the same; the commitment, cost structure and purpose are not. The right format depends on how much CFO time the business genuinely needs, for how long, and whether the need is a gap, an event or a permanent capability. The table below sets out how we advise clients to think about it.

Other ways to hire a CFO. This page covers full-time interim appointments. If you need sustained senior finance leadership a few days a month, our fractional CFO service is the better fit; for a consistent weekly commitment, see part-time CFO recruitment. For a permanent appointment, our CFO recruitment practice runs the full search, and if the role is really a hands-on finance leadership position below CFO level, we also place interim Finance Directors. Many clients use more than one: an interim CFO while the permanent search runs, or an interim who hands over to a fractional arrangement once the immediate pressure has passed.

Interim CFO or Interim Finance Director?

The titles are used loosely in the UK market, and the wrong one in a brief attracts the wrong candidates. As a working distinction, the CFO owns the financial strategy, capital structure and external relationships, while the Finance Director (in many mid-sized businesses) runs the finance function and its outputs. In a smaller business one person may do both; in a larger group they are separate roles. Our guide to when a firm needs a CFO and when it needs a Finance Director covers the distinction in more depth.

What an Interim CFO Typically Delivers in the First 90 Days

An interim CFO is paid to make progress quickly, so it is reasonable to expect a visible plan within the first weeks and measurable outputs within the first quarter. The exact list depends on the mandate, but the pattern we see in well-run assignments looks like this. Our executive onboarding guide covers how to set an interim up for that pace.

Days 1–30: diagnose and stabilise

• Take control of cash: a short-term cash flow forecast the board and bank can rely on, and clear authority over payments.
• Meet the lenders, auditors, key investors and advisers, and establish who expects what, by when.
• Assess the finance team, the month-end close, management information and systems, and identify the gaps that matter.
• Agree a written set of priorities and success measures with the CEO or chair.

Days 31–60: fix and deliver

• Board reporting that answers the questions directors are actually asking, with a reforecast where the budget no longer reflects reality.
• Progress on the specific mandate: the data room and model for a fundraise or sale, the lender plan for a covenant issue, or the controls for an audit problem.
• Quick wins in working capital, cost visibility and month-end timetable.

Days 61–90: embed and prepare to hand over

• A finance function that can run without the interim: documented processes, clear responsibilities and the right people in the right seats.
• Input into the permanent CFO brief, or a recommendation on whether a permanent, fractional or part-time successor fits best.
• A written handover covering open issues, upcoming deadlines and stakeholder commitments.

The Candidate Profile We Work With

Exec Capital’s interim CFO network is built around finance executives with the following:

Genuine CFO-level track record. Candidates who have held full CFO accountability — not Finance Director or VP Finance roles rebranded as CFO — in businesses of comparable scale, sector, and ownership type to the client. The difference between a CFO who has managed a P&L, board relationships, and investor communication, and a senior finance manager who has not, is significant and shows clearly in the first board meeting.

Sector-relevant experience. The financial challenges of a SaaS business, a professional services firm, a PE-backed industrial company, and a regulated financial services business are materially different. Exec Capital matches candidate sector experience to mandate requirements — not generalist finance credentials to any available role.

Transaction or situation-specific experience. Where the mandate involves a fundraising, M&A, distress situation, or finance function build, Exec Capital specifically identifies candidates with substantive experience in that situation type. A fundraising CFO and a turnaround CFO are different profiles, and placing the wrong one into the wrong mandate is the most common and most expensive mistake in interim CFO recruitment.

True interim mindset. Executives who have chosen the portfolio model and who bring the discipline of rapid diagnosis, clear prioritisation, and delivery against a defined mandate — not finance executives between permanent roles who will approach the engagement as a job rather than a project.

How we assess them. Every candidate we introduce has been interviewed against your brief, not just matched on keywords. We probe for specific evidence: the size and complexity of the businesses they have run finance for, what they personally owned in past transactions or turnarounds, how they handled a difficult lender or auditor, and why previous assignments ended. We check professional qualifications and membership standing, take references from people who saw their work at first hand, and, for regulated roles, consider whether the candidate is likely to satisfy the regulator’s fitness and propriety assessment. Our executive assessment guide explains the approach in more detail.

Interim CFOs at FCA-Regulated Firms: SMF2, SMF3 and the 12-Week Rule

Appointing an interim CFO at an FCA-authorised firm involves an extra layer of planning, because the role may be a senior manager function under the FCA’s Senior Managers Regime. Which function applies depends on the type of firm and whether the interim sits on the board.

• SMF2 Chief Finance function applies at banks and building societies, insurers and FCA Enhanced firms. At dual-regulated firms the PRA approves the appointment, with FCA consent. Our guide to hiring an SMF2-approved CFO explains what the regulators look for.
• SMF3 Executive Director is the function a board-level CFO at a Core firm typically holds, because SMF2 does not apply to Core firms. An interim CFO who is not appointed to the board at a Core firm may not need SMF approval at all, although they may fall within the certification regime. See our SMF3 Executive Director hiring guide.
• Payment and e-money institutions are outside SMCR. Their finance leaders do not hold SMFs, although the FCA assesses the people responsible for managing the business when it authorises the firm and when management changes.

Temporary cover. Where a senior manager leaves unexpectedly or is temporarily absent, a firm can put someone in to cover the role before approval is granted. Following the FCA’s Phase 1 SMCR reforms (PS26/6, in force from 24 April 2026), the temporary cover rule in SUP 10C.3A.6R gives firms up to 12 weeks to submit an application for the person providing cover, and the cover can continue while that application is determined. The FCA’s October 2026 consultation, CP26/37 (with the PRA’s CP14/26), proposes extending this to 18 weeks; the consultation closes on 22 January 2027, so treat 12 weeks as the rule until final rules are published. The same consultation proposes keeping SMF2 and SMF3 — and SMF16 and SMF17 — as pre-approved functions.

Approval timing. Under section 61 of the Financial Services and Markets Act 2000, the regulator must decide a complete application within three months, and the clock stops while it waits for information it has requested. In practice many applications are decided well inside that limit, but an incomplete Form A is the most common cause of delay. Our guide on how long FCA SMF approval takes sets out the current picture, and our urgent SMF appointment service is designed for exactly these departures.

The compliance seats often move at the same time. In smaller regulated firms the CFO may also have been carrying compliance oversight or money laundering reporting responsibilities. If the departure leaves the SMF16 or SMF17 role uncovered, we can place an interim Chief Compliance Officer, a fractional CCO, a fractional compliance officer to hold SMF16, or a fractional MLRO to hold SMF17 — usually one or two days a week, which suits most smaller firms better than a full-time hire.

IR35 and Engagement Structure for Interim CFOs

Most interim CFOs work through their own limited company, though some prefer an umbrella company or direct PAYE engagement. Where the off-payroll working rules apply, the status decision sits with the client for medium and large businesses, which must issue a status determination statement with reasons; for small private-sector clients, the interim’s own company makes the assessment. HMRC’s guidance on understanding off-payroll working (IR35) sets out the tests.

A full-time interim CFO who sits on the board, signs off accounts and manages staff can look a lot like an employee, so the status question deserves real attention rather than a template answer. Factors that commonly matter include whether the interim is engaged to deliver a defined outcome, the degree of control the business exercises over how the work is done, whether substitution is genuinely possible, and whether the interim carries any financial risk. Board appointments raise their own issues because statutory directors hold an office.

One point we are often asked about: the Companies Act size thresholds were raised for financial years beginning on or after 6 April 2025, which will take some businesses out of the “medium or large” category. HMRC’s April 2025 Employer Bulletin says the change has no practical impact for off-payroll working until 6 April 2027 at the earliest, because size is assessed on earlier years’ figures. Our guide to IR35 rules for senior executive engagements goes further; for a definitive view on a specific engagement, take tax advice.

Interim CFO Day Rates: UK Market

Interim CFO compensation in the UK is typically structured on a day rate basis for defined-term engagements. We do not publish a rate card, because a rate quoted without the context of the mandate is more likely to mislead than help. Rates vary by seniority, sector and mandate complexity, and the main drivers are:

• Scale and complexity. Group structures, multiple entities and currencies, and listed or institutional ownership all push rates up.
• Situation. Transaction, refinancing and distress mandates carry more intensity and personal exposure than a steady-state cover role, and are priced accordingly.
• Regulation. Roles at FCA-regulated firms that require SMF approval narrow the pool of suitable candidates.
• Commitment and location. Days per week, expected duration, travel and on-site requirements all affect the rate.
• Engagement structure. Whether the role sits inside or outside IR35 affects how candidates price their time.

The day rate we quote to you includes our fee, so you see one all-in figure per day rather than a candidate rate plus a separate agency charge. We give you a realistic range at briefing, based on the specific mandate and current candidate expectations. For permanent CFO pay context, see our salary guide for Chief Financial Officers.

For businesses seeking ongoing part-time or fractional CFO support rather than a full-time interim appointment, Exec Capital’s sister practice FD Capital’s fractional CFO service provides this model with an active network of finance leaders available across the UK. HMRC’s off-payroll working rules apply to interim CFO engagements, and we discuss the likely status position and engagement structure with clients at briefing, as set out above.

Engagement and Fees

Our fee structure is agreed at briefing and set out in writing before the search starts, so there are no surprises later. How it works depends on the format:

• Interim and fractional appointments are charged on a day-rate basis. The day rate includes our fee, and you are invoiced for days worked.
• Permanent CFO searches can be run on a retained or contingent basis, depending on the seniority of the role, how confidential it is and how hard the market is to search. Our guide to retained vs contingent executive search explains the difference.
• Interim-to-permanent conversion terms, if you think you may want to keep the interim, are agreed at the outset so the option is clear to everyone.

What is included: the briefing and role definition, market search, candidate interviews and assessment, an assessed shortlist, interview co-ordination, referencing, offer negotiation, help with engagement structure and IR35 questions, guidance on FCA approval or temporary-cover steps where relevant, and contact with both sides during the assignment.

Who We Place Interim CFOs With

Our interim CFO clients are typically businesses where the finance seat cannot be left empty and the stakes of getting it wrong are high:

• Private equity and venture-backed businesses — portfolio companies facing a CFO change mid-hold, a refinancing, a bolt-on acquisition or an exit process, often at the investor’s request. The UK Private Capital (formerly the BVCA) community sets much of the reporting expectation in this market.
• Owner-managed and family businesses — preparing for sale, succession or a first institutional investor, where the finance function has not kept pace with the business.
• Scale-ups — Series A to growth-equity businesses needing CFO capability for a fundraise or to meet new investor governance requirements. We also run permanent start-up CFO recruitment.
• FCA-regulated firms — banks, insurers, investment managers, brokers and other authorised firms where the CFO may hold SMF2 or SMF3.
• Businesses under financial pressure — covenant breaches, liquidity problems or stakeholder negotiations, where an interim CFO works alongside restructuring advisers.
• UK subsidiaries of international groups — where the local finance lead has left and head office needs continuity in UK statutory reporting, tax and audit.

Sectors include technology and software, professional services, manufacturing and industrials, consumer and retail, property and construction, healthcare, energy, and financial services. Searches are run from our London office at 167–169 Great Portland Street and our West Midlands office in Cannock, covering the whole of the UK.

Frequently Asked Questions

How quickly can an interim CFO start?

Interim CFOs can usually start much sooner than a permanent hire, because experienced interims are typically between assignments or on short notice rather than serving a long notice period. The single biggest determinant of speed is the quality of the brief: a clear statement of the situation, the deliverables and the decision-makers lets us search precisely and lets you decide quickly. We agree the timetable with you at briefing. Call 0203 834 9616 to discuss an urgent requirement.

What is the difference between an interim CFO and a fractional CFO?

An interim CFO works full-time or near full-time for a defined period — typically three to nine months. A fractional CFO works part-time on a fixed-day basis on an ongoing basis. Interim is appropriate where there is a genuine leadership gap, a transaction, or a situation requiring concentrated attention. Fractional is appropriate for businesses that need sustained senior financial leadership but not at full-time intensity. Exec Capital runs fractional and part-time CFO searches as well, and our sister practice FD Capital specialises in fractional and part-time CFO and FD arrangements.

Does the interim CFO need to be ICAEW or CIMA qualified?

For most CFO mandates, a professional accounting qualification — ACA, ACCA, CIMA, or equivalent — is a baseline expectation, particularly where the role involves statutory reporting, audit management, or investor-facing financial communication. However, some transaction-focused CFO mandates may suit candidates with CFA or investment banking backgrounds. Exec Capital assesses qualification requirements as part of every brief and advises accordingly.

What should I look for when hiring an interim CFO?

The most important factors, in order: relevant sector experience, comparable business size and stage experience, specific experience in the situation type the business is facing (transaction, distress, growth, or bridging), genuine CFO-level accountability in previous roles rather than senior finance management, and genuine interim working experience rather than a candidate between permanent positions. Exec Capital’s briefing process covers all of these systematically and produces a shortlist filtered against each criterion.

Can an interim CFO also help recruit the permanent CFO?

Yes — and this is one of the most valuable contributions a good interim CFO makes. Having lived the role in your specific business for several months, they have the most accurate possible understanding of what the permanent appointment requires. Their input into the permanent brief, briefing of search firms, and assessment of final candidates significantly improves the quality of the permanent appointment and reduces the risk of a costly mis-hire.

How much does an interim CFO cost?

Interim CFOs are paid a day rate, which depends on the size and complexity of the business, the situation, any regulatory requirement, the days per week and the IR35 position. The day rate we quote includes our fee, so you see a single all-in figure. We give you a realistic range at briefing for your specific mandate rather than a generic rate card.

Is an interim CFO inside or outside IR35?

It depends on the facts of the engagement, not the job title. For medium and large private-sector clients, the client decides and must issue a status determination statement; for small clients, the interim’s own company decides. Full-time, board-level interim roles need careful assessment. We discuss the likely position with you at briefing, but the determination is yours to make and specialist tax advice is worth taking on borderline cases.

Does an interim CFO at an FCA-regulated firm need approval?

Often, yes. At banks, insurers and Enhanced firms the CFO role is SMF2 Chief Finance; at Core firms a board-level CFO typically holds SMF3 Executive Director. Since 24 April 2026 firms have up to 12 weeks to submit an application for someone providing temporary cover after an unexpected departure, and the cover can continue while the application is decided. Payment and e-money institutions are outside SMCR.

How long does an interim CFO assignment last?

Commonly three to nine months, but the right length is set by the mandate: a transaction runs to completion, a bridging appointment runs until the permanent CFO arrives, and a turnaround runs until the business is stable. Assignments are often extended by agreement, and a clear end point should be written into the engagement from the start.

Can we make the interim CFO permanent?

Yes, if both sides want it. Some interims are open to a permanent role; many prefer portfolio work. If you think conversion is a possibility, say so at briefing so we can look for candidates open to it, and so conversion terms are agreed at the outset.
