TL;DR
Part time CFO UK support typically means a senior finance leader working with you one or two days per week to stabilise cashflow, upgrade management reporting, and advise on big decisions (funding, pricing, investment and risk) without the cost of a full-time hire.
As a reference point for the wider pay market, the Office for National Statistics (ONS) estimates average weekly earnings at £753 for total pay and £697 for regular pay in April 2026 (Feb–Apr 2026 period) (<a href="https://www.ons.gov.uk/employmentandlabourmarket/peopleinwork/employmentandemployeetypes/bulletins/averageweeklyearningsingreatbritain/june2026">ONS average weekly earnings</a>).

If you are searching for a part time CFO UK, you are usually past the point where a good accountant and a capable bookkeeper can keep the business ahead of the numbers. Turnover is rising, payroll is heavier, VAT and corporation tax have real timing consequences, and one slow-paying customer can trigger a chain reaction.
The problem is not ‘doing finance’ — it is having someone senior enough to shape decisions, challenge assumptions, and build a finance rhythm the leadership team can rely on. A part-time CFO model gives you that capability at a practical commitment level: one or two days per week, focused on the highest-impact work.
This guide explains what a part-time CFO actually does, what you should expect in the first 30–90 days, common fee structures, and how to choose the right person for an owner-managed UK business. It also clarifies the difference between part-time, fractional and interim — because suppliers often use those terms loosely.
What is a part-time CFO (and how is it different from fractional or interim)?
A part-time CFO is a senior finance leader who joins your business for a set time commitment each week or month (for example, one day per week or two days per month). They take ownership of the finance agenda at leadership-team level: cashflow, performance reporting, controls, risk, and decision support.
In practice, ‘part-time’ and ‘fractional’ are very similar. Fractional tends to emphasise that the CFO is part of your leadership team, but only for a fraction of a full-time role. ‘Interim’ usually means a short, full-on bridge while you hire or cover a gap — often three to nine months — and can be closer to a full-time time commitment.
Modern CFO work is not just producing accounts; it is building better decision-making and cross-functional change. ICAEW describes finance transformation as finance teams taking on business partnering and finance leaders often leading transformation programmes that may not be limited to finance (<a href="https://www.icaew.com/technical/business/finance-transformation">ICAEW on finance transformation</a>). That is exactly why many owner-managed firms bring in a part-time CFO: to move from ‘reporting the past’ to ‘steering the next quarter’.
What does a part time CFO deliver in the first 30–90 days?
A good part time CFO UK engagement is structured and visible. You should not be guessing what is happening ‘in finance’ — you should see a clear plan, early wins, and a regular reporting cadence.
- A cashflow model you can run weekly (with realistic assumptions, sensitivities, and a clear ‘minimum cash’ threshold).
- A monthly management pack the leadership team actually uses: revenue, gross margin, overheads, working capital, and a short commentary on what changed and why.
- A simple forecast process (rolling 13-week cash and a 12-month P&L view) with owners for each assumption.
- A working capital plan: debtor days, creditor days, stock turns, and practical actions to release cash.
- Controls that scale: approvals, payment runs, expense rules, and clearer month-end close responsibilities.
- Board-level decision support for pricing, hiring plans, capex, and funding — including ‘what happens if we miss plan by 10%?’ scenarios.
- A short ‘finance operating model’ so your bookkeeper/FC knows what good looks like and what to prioritise each week.
How much does a part time CFO cost in the UK?
There is no single market rate because it depends on business complexity, sector, location, and whether you need hands-on delivery or mostly senior decision support. However, you can sanity-check costs against the full-time market: if a full-time FD/CFO package is not yet justified, a part-time CFO gives you leverage.
Recruiters’ UK benchmarks commonly place Finance Director salaries in the high five to low six figures depending on size and location. For example, Robert Half’s UK guide lists a Finance Director average salary range of £89,750–£138,000, with higher upper ranges in Central London (<a href="https://www.roberthalf.com/gb/en/insights/career-development/highest-paying-finance-jobs-in-the-uk">Robert Half UK finance salaries</a>).
A typical part time CFO UK arrangement is priced as either a day rate or a monthly retainer linked to a time commitment. Focus less on the label and more on three practical questions: how many days per month you will actually get, what the CFO will personally do versus delegate, and what outcomes you expect by day 30 and day 90.
Tip: if your CFO is helping you tighten compliance and governance, keep an eye on upcoming UK filing reforms too. The government has confirmed that from April 2028, small companies and micro-entities will need to file profit and loss accounts (with the option to opt out of publication) and all companies will need to file accounts via commercial software (<a href="https://www.gov.uk/government/news/companies-house-to-bring-in-changes-to-accounts-filing-from-april-2028--2">GOV.UK Companies House filing changes</a>).
When does hiring a part-time CFO make sense?
A part-time CFO is most valuable when the business has real decisions to make — and the cost of a wrong call is meaningful. You do not need a part-time CFO just to produce statutory accounts; you need one when finance must actively shape the plan.
- You are growing, but cash feels tight even when sales look strong (working capital is the real constraint).
- You need funding (overdraft, invoice finance, term debt, equity) and want an investor-ready story with credible numbers.
- Margins are drifting and you cannot quickly explain why by product, customer segment, channel or project.
- Month-end results arrive too late to be useful, or different reports contradict each other.
- You are adding complexity: new site, new country, new product line, acquisition, or a major systems change.
- You are over-reliant on one person in finance, and risk increases if they leave.
For many owner-managed firms, the ‘sweet spot’ is turnover roughly £2m–£20m: big enough that decisions need sharper numbers, but not always big enough to justify a full-time CFO. That range also matches today’s planned persona for this article.
How to choose the right part-time CFO
Choosing a part-time CFO is a senior hire. Your best indicator is not a slick CV; it is whether they can quickly understand your business model and ask the right questions. Use these checks.
- Evidence of impact at your size: examples of cash improvements, margin recovery, funding, or control upgrades in owner-managed firms.
- Clarity on time commitment: what ‘one day a week’ means in practice (on-site vs remote, availability for urgent decisions).
- Ability to build a finance rhythm: weekly cash, monthly pack, quarterly forecast — with named owners and deadlines.
- Commercial judgement: can they challenge pricing, customer profitability, and hiring decisions without hiding behind spreadsheets?
- Speed of start and no long-term tie-ins: you should be able to start within a week and scale up or down without a painful exit.
- Communication style: you want plain English, not jargon, and a CFO who can influence sales, ops and delivery teams.
Finally, agree what ‘good’ looks like by day 30 and day 90. If you cannot describe the outcomes, you will struggle to judge value — and the engagement will drift into general support.
Frequently asked questions
Is a part time CFO UK the same as a fractional CFO?
Often, yes. In the UK market, ‘part-time’ usually describes the time commitment (for example, one day per week), while ‘fractional’ emphasises that the CFO is embedded in your leadership team but for a fraction of full-time. What matters is the deliverables, decision support, and reporting rhythm you get.
How many days a month do I need a part-time CFO?
Most owner-managed firms start with 2–4 days per month, then adjust. If you are raising funding, implementing a new system, or rebuilding reporting, you may need a heavier first 60–90 days. A good CFO will propose a ramp-down plan once the core finance rhythm is in place.
Can a part-time CFO help me raise funding?
Yes — and it is one of the most common reasons to hire one. The CFO will help you build a credible forecast, stress-test assumptions, prepare an investor or lender pack, and answer questions quickly during due diligence. They should also help you decide which funding route fits your cashflow and risk profile.
What should I ask a part-time CFO in the first meeting?
Ask how they would get control of cash in the first 30 days, what your monthly reporting pack should look like, and what they would change about your current decision-making process. Then ask for examples of similar businesses where they improved cashflow or margins, and how they worked with the existing finance team.
