Fractional, interim or part-time finance director: which one to choose?

Fractional CFO, interim CFO, part-time finance director: three ways to access senior finance leadership without a full-time hire — but for different needs. This comparison helps you choose.

The three models at a glance

• Part-time / fractional — permanent and light: one to three days a week, ongoing. To steer an SME's finances durably.
• Interim — temporary and intensive: a 4 to 12 month full-time mission for a specific situation.
• Outsourced — the umbrella term: the common idea is not bringing the role in-house.

How to choose

Growing and finance is now critical → fractional / part-time. A gap to cover or a deal to run → interim. Want to test before hiring → start fractional, internalise later.

And the cost?

All three are priced on a day rate (£600 to £1,400 in 2026). Fractional is cheapest over a year; interim is the most concentrated. See the cost guide.

Frequently asked questions

Can you switch between models?

Yes — an interim mission can continue as a fractional arrangement once the situation stabilises.
