Fractional Chief of Staff Jobs UK

A fractional Chief of Staff is an experienced operator who works alongside a CEO part-time — typically one to three days a week, usually on a monthly retainer — providing the leverage of a full-time CoS without the salary, equity or notice period. The role is a force-multiplier for the CEO: it owns the leadership-team operating rhythm, takes direct ownership of two or three critical cross-functional programmes (fundraising, integration, expansion), prepares board and investor materials, and synthesises information across the business so the CEO makes better decisions faster. A CoS works *through* functional leaders rather than commanding a function directly.

Distinct from: a [COO](/fractional-coo-jobs-uk) (who owns operations and carries operational KPIs — a CoS coordinates across functions including the COO, but doesn't own delivery); an [Executive Assistant](/fractional-executive-assistant) (who manages calendar, travel and inbox — a strong EA buys back ~5–8 hours of CEO time a week, a strong CoS buys back ~15–20 while improving decision quality; the two are complementary, and many scale-ups run both); a strategy consultant (who advises from outside on defined projects — a CoS executes from inside on an ongoing 12–24 month basis); and a deputy CEO / No. 2 (which usually implies direct operational authority and is better titled COO or MD). If the need is "run operations" → COO. If it's "make the CEO more effective" → CoS.

The role typically breaks down across seven core responsibilities:

• Leadership-team rhythm & coordination (~30–40% of time) — running the weekly leadership team meeting, maintaining cross-functional alignment, ensuring decisions get implemented across functions • Strategic-initiative programme leadership (2–3 concurrent) — owning complex cross-functional programmes like fundraising, acquisition integration, market expansion that need senior orchestration • Board & investor communication prep — preparing board packs, investor updates, key metrics dashboards, and ensuring the CEO has clear talking points and supporting data • Information synthesis & decision prep — distilling complex cross-functional information into clear recommendations, running scenario analysis, preparing CEO for key decisions • Strategic hiring & senior-team development — supporting C-level and VP-level hiring, onboarding senior hires, developing leadership team effectiveness • External-stakeholder coordination — managing key customer relationships, investor relations, strategic partnerships that require CEO-level attention but benefit from coordination • Operating cadence & decision architecture — implementing OKRs, governance structures, decision-making processes that keep the company running smoothly as it scales
