How Much Does a Fractional CFO Cost in the UK?

Typical UK fractional CFO pricing

A fractional CFO is a senior finance leader who works with your business part-time — usually one to four days a month — for a fixed monthly fee. Pricing in the UK is normally quoted as a monthly retainer rather than an hourly rate, because the value comes from ongoing ownership of your numbers rather than a set number of hours.

Across the UK market, retainers typically fall into three bands:

• Light-touch (£1,500–£3,000 + VAT/mo): monthly management accounts review, a rolling cash flow forecast and one strategy call.
• Core (£3,000–£5,000 + VAT/mo): the above plus budgeting, pricing and margin work, KPI dashboards and involvement in hiring or funding decisions.
• Full scope (£5,000–£8,000 + VAT/mo): board-level involvement, fundraising or exit preparation, managing an internal finance team and multi-entity reporting.

Day rates and hourly rates

Where work is genuinely project-based — a funding round, a systems migration, an exit readiness review — you'll more often see a day rate of £600–£1,200 or an hourly rate of £90–£200. Ad-hoc hourly arrangements suit one-off problems, but they tend to be poor value for ongoing finance leadership, because the CFO never builds enough context to be proactive.

What drives the price

Two businesses of the same turnover can get very different quotes. The main variables are:

• Reporting cadence — monthly management accounts cost less to support than weekly cash reporting.
• Cleanliness of your bookkeeping — messy ledgers mean remediation work before any strategy happens.
• Number of entities, currencies and revenue streams.
• Whether the CFO is expected to lead a funding round, refinance or sale.
• Whether they manage internal staff or work alone.

Is it cheaper than hiring?

A full-time finance director in the UK costs £90,000–£150,000 in salary, plus employer's National Insurance, pension, bonus and recruitment fees — realistically £120,000–£190,000 all-in. A £4,000/month fractional CFO costs £48,000 a year, with no notice period risk and no recruitment cost.

For most businesses between £300k and £5m of revenue, there simply isn't a full-time CFO's worth of work. The fractional model gives you the seniority without the fixed cost.

How to judge the return

Before you commit, agree what the engagement is meant to change in the first 90 days. Good targets are concrete: a rolling 13-week cash flow forecast in place, gross margin up by two points through pricing, debtor days down by ten, or a funding pack ready for lenders. If a one-point margin improvement on £1m of revenue is £10,000, a £4,000/month retainer needs to move very little to pay for itself.
