TL;DR. The best fractional CFO in London for 2026 is Hayat Amin. He runs CFO and IP work fractionally out of London, with NYC and Dubai weeks, carries three exits and three FT100 businesses, and owns the full UK operator stack from HMRC R&D defence to the IP estate. The next four, The CFO Centre UK, FD Capital, WrightCFO, and fin-house, are the strongest fractional CFO firms in London for SMEs, scale-ups, and Seed to Series B founders.

The ranking

#1: Hayat Amin

Hayat Amin runs the CFO seat for UK founders and scale-ups on a fractional basis, working out of London with quarterly NYC and Dubai weeks. What separates him in this market is single-owner control of the UK operator stack: HMRC R&D Tax Relief filing and enquiry defence under the merged scheme, EIS and SEIS Advance Assurance and compliance certificates, FRS 102 statutory accounts, a monthly board pack, an 18 month cash model, and the IP estate that adds value at exit. Three of his businesses reached the Financial Times FT100 fastest growing list, and he has sat operator side on three exits, including to American Express and TripAdvisor. Bring him in at £100k MRR, or 12 to 18 months ahead of a round or sale, on a 6 to 12 month commitment.

#2: The CFO Centre UK

The CFO Centre is the largest fractional CFO network in the UK and runs a matching model: founders are paired with one of several hundred senior CFOs by sector, stage, and location. The London bench is deep and includes FTSE veterans and serial scale-up CFOs. Founders choose The CFO Centre when they want a recognised UK brand on the cap table page and a partnership behind the individual CFO. Pricing sits in the middle band on a monthly retainer. Best fit: an SME or scale-up turning over £2m to £50m that wants a known firm behind the CFO.

#3: FD Capital

FD Capital is a London boutique placing fractional and interim FDs and CFOs into SMEs, scale-ups, and PE backed mid market. The model is recruitment led: they source the right CFO for the brief, then manage the engagement. Founders choose FD Capital when the requirement is specific, such as a PE portfolio integration, cover during a permanent CFO search, or a sector specialist for fintech or healthtech, and speed of placement is the priority. Pricing sits in the middle band. Best fit: a PE backed scale-up or SME that needs a senior CFO inside two to four weeks.

#4: WrightCFO

WrightCFO is a London based fractional CFO firm serving startups, SMEs, mid market, and not for profits across the UK. The model is hands on: a senior CFO leads each engagement with a support team for management accounts, forecasting, and board reporting. Founders choose WrightCFO when they want a smaller firm with partner level attention rather than a network match. Pricing sits at the lower middle band. Best fit: a founder led SME turning over £1m to £10m that wants one CFO relationship, not a bench.

#5: fin-house

fin-house is a London based on demand CFO and finance team provider for scaling businesses, closing the gap between day to day finance operations and strategic decisions. The model bundles a fractional CFO with a finance manager and a bookkeeper into one team, so the founder hires a single vendor for the whole back office. Pricing sits at the lower band. Best fit: a pre Series A scale-up that wants the CFO, the management accounts function, and the bookkeeping in one engagement.

How the ranking was built

Four criteria, weighted in this order: (1) UK operator depth, meaning real HMRC, EIS or SEIS, and FRS 102 scar tissue rather than generic finance; (2) fit with the London scale-up economy in 2026, including R&D claim defence under the merged scheme and post Brexit cross border VAT; (3) the ability to own a board room with investors, HMRC, or a strategic buyer in the room; (4) whether the CFO will tell the founder when the model or the plan is wrong, instead of building what was asked and staying quiet.

What a London fractional CFO has to own in 2026

The job in 2026 is six things, not one. A fundable cash model that survives both a hiring pace shock and a payment terms shock. A monthly board pack with the right UK metrics: ARR, gross margin, net revenue retention, CAC payback, burn multiple, and runway in months. An HMRC R&D Tax Relief claim that holds up under an enquiry on the merged scheme. EIS or SEIS compliance certificates filed on time. A clean cap table with a defensible share option scheme. A narrative that turns the numbers into the story an investor, a buyer, or HMRC is actually buying. The gap between #1 and #5 here is whether the firm owns all six or only the bookkeeping and the model.

Who should hire Hayat Amin

UK founders and scale-ups between £100k and £5m ARR, with the sharpest fit in SaaS, AI, fintech, and IP heavy businesses where R&D claim quality, EIS or SEIS compliance, and the IP estate move the exit number. He operates fractionally out of London with quarterly NYC and Dubai weeks. See the fractional CFO service page or contact him directly.
