Fractional CEO Jobs UK

A fractional CEO is an experienced chief executive who leads a company part-time — typically 1–3 days a week — rather than as a full-time appointment. Also called a portfolio CEO or part-time CEO, they often work across several businesses at once.

They take genuine executive ownership: strategy, leadership of the senior team, board and investor relationships, and accountability for performance — distinct from a consultant, who advises and exits without owning the outcome.

Fractional CEOs build and embed; interims cover a defined gap; NEDs govern but don't run the business.

Common when a founder wants to step back from day-to-day leadership, a scale-up needs experienced CEO-level leadership it can't yet justify full-time, or a PE/investor needs senior leadership in a portfolio company. *Cited: FD Capital Part-Time CEO 2026; Leadership Services 2026; Alpha Apex 2026*

Portfolio executive earnings for practitioners

For practitioners: earnings derive from day rate × days across a portfolio (£800–£1,500/day; 1–3 d/wk per client across several clients). Portfolio income varies based on number of clients and day commitment per client — this is portfolio income, not a single salary.

Inside vs Outside IR35 Explained

IR35 legislation determines whether a contractor is taxed as an employee or can operate through their limited company. For fractional CEO roles, this affects take-home pay by 20-30% and engagement structure.

Small clients are exempt — the contractor self-determines. Medium, large, and public sector clients must issue a written Status Determination Statement (SDS) to both contractor and fee-payer with reasoning. HMRC requires "reasonable care" — blanket determinations fail this test.

What Keeps Portfolio Executives Outside IR35

Multiple concurrent businesses — portfolio CEOs working with 2-4 companies simultaneously demonstrates genuine business operation. High-level strategic autonomy — setting direction, choosing methods, determining priorities without day-to-day supervision. Financial risk — fixed retainers regardless of company performance.

Board-level accountability — genuine executive responsibility for outcomes, not just advisory input. Own resources — using personal systems, networks, methodologies. No mutuality of obligation — either party can terminate with agreed notice.

April 2026 Changes

Small-company thresholds rise from April 2026 — more UK businesses fall outside off-payroll rules, shifting determination back to contractors. This benefits the fractional CEO market by reducing IR35 assessment burden on growing companies.
