Fractional FC for FCA-Regulated Firms: What Works

Small authorised firms have a genuine problem: the regulatory obligations are real, they are dated, and they do not fill a week. A firm with fifteen staff and a MIFIDPRU permission needs someone who can calculate own funds, submit returns and — if it holds client money — oversee a daily reconciliation, and it cannot justify a full-time Financial Controller with that experience. Fractional is the obvious answer and it is frequently the right one. It also has limits that matter more here than in any commercial setting, and this guide is honest about both.

Why the model fits

Three reasons the arrangement works well in regulated firms.

The obligation is real but bounded. A quarterly return, a monthly capital calculation and a documented ICARA is genuine work and it is not five days a week at a small firm. Paying for a full-time regulated FC at £95,000 to do two days of regulated work is exactly the mismatch fractional exists to solve.

The scarcity works in your favour. Fractional practitioners with CASS, safeguarding or prudential experience — on top of the baseline ICAEW, ACCA or CIMA qualification — are thin on the ground, but the ones who exist have usually seen several firms — which means pattern recognition a first-time permanent hire will not have. Our guide to the regulated finance hiring market covers the supply picture.

And the work is largely review. Financial control compresses because much of it is checking rather than producing — and the regulatory half is disproportionately review, judgement and documentation.

Where the model has real limits

This is the part that gets skipped in most discussions of fractional finance, and in regulated firms it matters.

Daily obligations do not compress. Where the firm holds client money under CASS or safeguards relevant funds, the reconciliation is daily. A fractional FC present on Tuesdays and Thursdays cannot perform it — somebody in the business does, and the FC reviews. That is a workable arrangement, and it means the fractional appointment is the oversight rather than the operation. Our guide to CASS oversight versus operations covers the split.

Personal accountability sits awkwardly with part-time presence. Where a prescribed responsibility is allocated under the Senior Managers and Certification Regime, the individual holding it is answerable in full regardless of how many days a week they attend. Some fractional practitioners will accept an SMF; many will not, and firms should establish this early rather than at offer stage.

Something urgent will arrive on a day they are not there. A breach, a supervisory query, a shortfall. The arrangement needs an agreed escalation route rather than an assumption.

And a firm with no other regulatory expertise is exposed. A fractional FC visiting twice a week, in a firm where nobody else understands the obligations, is a single point of failure who is also frequently absent.

When it works well

Four configurations where the arrangement is genuinely strong.

The firm has operational capability and needs oversight. Someone internal performs the daily reconciliation; the fractional FC reviews it, owns the calculation, handles the returns and manages the audit. This is the best fit by a distance, and it is also better governance than one person doing everything.

The regulatory workload is genuinely periodic — quarterly returns, an annual ICARA refresh, monthly capital monitoring — with no daily client money obligation. Common in firms that do not hold client money, and the model fits cleanly.

Building the function before a permanent hire. A newly authorised firm using an experienced fractional FC to design the process, document it and specify the permanent role. Our guide to hiring finance for a newly authorised firm covers that sequence.

Or alongside an existing commercial FC — the firm has a capable Financial Controller without regulatory experience, and buys a day a week of specialist oversight rather than replacing them. An under-used arrangement and frequently the best value available.

When to hire permanently instead

Where client money is material and the firm has no operational capability. Someone has to perform the daily reconciliation, and if nobody internal can, the requirement is full-time.

Where an SMF responsibility must sit with the finance lead and no fractional practitioner will accept it.

Where the firm is growing fast enough that the regulatory workload will fill a week within a year. Appointing fractionally and re-recruiting twelve months later costs more than hiring correctly once.

And where supervisory attention is elevated — a firm under increased engagement needs someone present, not someone reviewing.

What to test before appointing

Beyond the standard fractional questions, five that are specific to this.

1. Which regimes have you actually worked under? CASS 5, 7 or 15, safeguarding, MIFIDPRU — they are different jobs, as our guide to CASS 7 versus CASS 15 sets out.

2. Will you accept an SMF responsibility? Ask directly and early.

3. How do you oversee a daily reconciliation you do not perform? Look for a described method — sampling, exception review, ageing analysis — rather than a general assurance.

4. How many other regulated clients do you have, and what would you do if two had an issue in the same week? Capacity honesty matters more here than in commercial engagements.

5. What would you check in your first week? Experienced regulated practitioners start with the permissions, the client money position and when the calculation was last independently reviewed.

Our guides to hiring regulatory experience and regulated versus commercial FC cover the wider assessment.

What it costs

Regulated fractional work prices 15–25% above the commercial equivalent, reflecting the same scarcity that drives the permanent premium. The half-day oversight arrangement in row four is the one most firms overlook and frequently the best value — it buys the specialist judgement without duplicating capability the firm already has.
