A fractional Financial Controller is a qualified accountant, usually ACA, ACCA or CIMA, with full Financial Controller capability, who works for your business on a part-time, ongoing retainer rather than as an employee. They provide the same close management, audit oversight, financial controls and management accounts review that a permanent FC provides, but on one or two days a week rather than five. The cost is typically around 35–55% of the all-in cost of employing a permanent Financial Controller, depending on the days agreed and the seniority of the individual.
Accountancy Capital places fractional Financial Controllers across the UK, mostly for businesses of roughly £2m–£15m revenue where the FC-level work is real but does not yet fill a week. It is currently the most requested service we offer. This page explains what a fractional FC does, what one typically costs, when the model is right and when it is not, and how our fractional placement service works. For a shorter explainer on the role itself, see what is a fractional Financial Controller?, and for the wider service see our fractional finance recruitment hub.
What a fractional Financial Controller does
A fractional FC performs the same core functions as a permanent Financial Controller, scoped to the days agreed. A typical one-day-a-week engagement covers:
- month-end close oversight and sign-off;
- review of the management accounts, with commentary the managing director can act on;
- management of balance sheet reconciliations;
- the relationship with the external auditor;
- maintenance of the financial controls; and
- direction of whoever does the transactional work, whether that is an in-house bookkeeper, an accounts assistant or an outsourced bureau.
A two-day-a-week engagement usually adds production of board-ready management accounts, ownership of the budget and reforecasts, oversight of the accounting system and proactive financial advice to the CEO or managing director.
What a fractional FC does not normally do at one or two days a week is equally important. They do not process day-to-day transactions; that is the bookkeeper’s or accounts assistant’s job. They will not answer every ad hoc query within the hour, so urgent questions outside the agreed days need a clear protocol written into the engagement. And they will not run a complex multi-entity consolidation at the pace of a full-time Group FC. Our guide to fractional FC engagement models covers how days and scope are usually matched.
When a fractional FC is the right model
| Scenario | Fractional FC? | Why |
|---|---|---|
| Business at £1m–£5m revenue, outgrowing its bookkeeper | Yes | FC scope is one to two days a week; full-time not justified |
| Business at £5m–£12m, permanent FC not yet affordable | Yes | FC-quality oversight at a fraction of the permanent cost |
| PE-backed business needing an FC two days a week | Yes | PE-experienced fractional FCs are available on retainer |
| Business at £12m+ with full-time FC scope | No | Volume justifies a permanent FC |
| Urgent, full-time gap cover | No | Use an interim FC; fractional is not a gap-cover model |
| Investor relationship and fundraising leadership | No | That is CFO scope; consider a fractional CFO |
The model works when the genuine FC-level work fills one to two days a week. A business that underestimates the volume, and expects one day a week to produce what a full-time FC would, is setting the engagement up to fail. We talk through scope before every fractional brief, and our article on seven signs you are ready for a fractional FC is a useful self-check. If the need is really cover for a departure, a year-end or a systems project, our interim Financial Controller recruitment service is the better fit.
Fractional FC retainers and day rates
Most fractional FCs work on an annual retainer billed monthly. Typical ranges by region:
| Engagement | London (annual) | South East | Midlands and North |
|---|---|---|---|
| 1 day per week | £29k–£39k | £25k–£33k | £22k–£29k |
| 1.5 days per week | £40k–£52k | £34k–£44k | £30k–£39k |
| 2 days per week | £52k–£68k | £44k–£58k | £39k–£51k |
| 3 days per week | £74k–£95k | £63k–£81k | £56k–£72k |
For comparison, the all-in cost of employing a permanent Financial Controller in London is typically £82k–£140k a year once salary, employer’s National Insurance, pension and benefits are included. A two-day fractional FC in London at £52k–£68k therefore costs roughly half of a permanent hire, with the exact proportion depending on the seniority of the permanent FC you would otherwise employ. That saving only holds where the FC-level work genuinely fills two days. Additional days beyond the retainer are normally charged at an agreed day rate.
Rates move with location, sector, regulatory complexity and whether the business is PE-backed. Our fractional FC rates UK guide has the detailed day-rate comparison, and the Financial Controller salary guide sets out permanent salaries if you want to run the comparison yourself.

Fractional FC vs permanent FC vs outsourced accounting
These three options are often compared as if they were interchangeable. They are not: each buys something different.
| Fractional FC | Permanent FC | Outsourced accounting | |
|---|---|---|---|
| What you buy | Qualified oversight and accountability | The same, full-time and embedded | Processing and production |
| Time | 1–3 days a week, ongoing | 5 days a week | Defined monthly scope |
| Typical cost (London) | £29k–£68k a year for 1–2 days | £82k–£140k a year all-in | Typically £800–£3,000 a month |
| Designs controls and owns the close? | Yes | Yes | Rarely |
| Best for | £2m–£15m businesses with part-time FC scope | Full-time FC scope, larger teams | Transaction volume and compliance filings |
Outsourced bookkeeping is not a substitute for a fractional FC. A bookkeeper or bureau processes transactions, keeps the ledgers and produces the trial balance. The fractional FC manages the close, reviews the accounts and provides financial leadership. The business that needs a fractional FC usually already has transactional processing covered and needs the qualified layer that turns that data into reliable management accounts and a reconciled balance sheet. If the real problem is processing, hire a bookkeeper; a fractional FC is the wrong answer to it. Many businesses use both, and our guide to fractional FC vs outsourced accounting explains how the hybrid works. See also Financial Controller vs outsourced finance.
A permanent FC is better once the work fills the week. When the close, reporting, audit and team management add up to a full-time job, a permanent hire is usually better value and keeps knowledge in the business. Our Financial Controller recruitment service handles permanent searches, where shortlists typically follow within one to two weeks. For a first appointment, your first Financial Controller covers the transition.
Genuine portfolio FC vs permanent FC between roles
The most important distinction in this market is between portfolio professionals who have chosen fractional work as their main way of working, usually holding two or three engagements at once, and permanent FCs between roles who take fractional work as a bridge while they look for their next full-time job. The bridge candidate takes weeks to become fully productive and may then leave after a few months when the permanent offer arrives. The genuine portfolio FC builds knowledge of your business over months and years and has no plan to leave.
We prioritise candidates who have been working in the fractional model for some time and already hold other client engagements, and we ask every candidate directly about their plans. If you want a committed portfolio practitioner rather than a bridge candidate, say so in the brief and we will screen for it. Our guide to portfolio Financial Controllers covers what to expect from one.
How Accountancy Capital places fractional FCs
Accountancy Capital is one of the five specialist firms of FD Capital Group, focused on qualified finance below director level. Fractional Financial Controllers sit at the centre of that work. Our process is short:
- Scoping call. A consultant talks through the scope, days and budget, and tells you honestly whether fractional, interim or permanent fits. We respond the same working day.
- Targeted approach. We contact the specific portfolio FCs whose sector, systems and availability match the brief, rather than advertising and waiting.
- Shortlist. For fractional and interim roles, candidates typically follow within days.
- Interviews and terms. We arrange meetings, help agree scope and retainer, and stay in touch through the early months. Fees are agreed in writing before a search starts.
How to write the brief
The briefs that produce the strongest match contain six elements: the scope of work (management accounts, year-end audit, balance sheet, team direction); the days per week and whether the role is mainly on-site or remote; the accounting system; the finance team below the FC and what they can do unaided; the start date, and whether the urgency justifies an interim while the fractional search runs; and revenue and ownership structure, because these determine the experience level and the retainer. We also place fractional FCs into specialist settings, including PE-backed businesses, SaaS companies and FCA-regulated firms.
The engagement agreement
A fractional engagement should be set out in a written agreement before work starts. The key elements are the specific scope and deliverables the FC will own; the agreed days per week and whether on-site or remote; the day rate for additional days; the notice period, often around three months; handover obligations at the end; and the IR35 status assessment. The agreement protects both sides: the business from a departure without proper handover, and the FC from scope creep beyond the retainer. We can talk you through the terms that are normally included.
IR35 and employment status
The IR35 position should be assessed before the engagement begins. A fractional FC who works for several clients on a portfolio basis is generally more likely to fall outside IR35 than one who works only for you on terms that resemble employment, but every engagement turns on its own facts. If your business is medium or large, you are responsible for the status determination under the off-payroll working rules, and HMRC’s employment status tool is a reasonable starting point. We recommend both parties take advice from a qualified employment tax adviser; our page on employment tax, IR35 and benefits in kind gives the background.
The first three months
The first three months matter most. In that time the fractional FC learns the business, builds a working relationship with the CEO or MD, runs the first one or two closes and identifies the priority improvements. A well-run engagement has a written scope agreed before day one, a first-month review in which the FC presents findings on the current state of the finance function, and a 90-day plan agreed by the end of month one. Our article on a fractional FC’s first 90 days sets out a typical plan. Directors remain responsible for keeping adequate accounting records under the Companies Act 2006, so the early review of records and controls is worth doing properly.
For candidates: registering as a portfolio FC
