Fractional COO — UK
Hire a fractional COO in the UK
Senior operations leadership for technology, hardware and manufacturing businesses — 1 to 3 embedded days a week, without the £150k–£250k+ cost of a permanent COO hire. Led by Dr Gareth Mills, DBA, MBA, MSc, CEng.
Why companies hire a fractional COO
When a COO hire makes sense — and when fractional is the better answer
Most scaling businesses reach a point where the founder can no longer run operations personally, but a full-time COO hire is too early, too slow or too expensive.
You need an operator, not another advisor
A fractional COO chairs your operating reviews, owns the delivery plan and unblocks decisions — leading from inside the business, not commenting from the sidelines.
Full-time is too soon, too slow, or too expensive
A permanent COO costs £150k–£250k+ fully loaded and takes 4–6 months to hire. A fractional COO starts in weeks, at a fraction of the cost, and scales down as your team takes over.
Investors expect operational proof
Funding readiness means an operating plan that survives diligence: manufacturing strategy, quality systems, supply chain resilience and a team structure that can scale.
Regulated products need senior hands
CE/UKCA marking, ISO 9001, supplier audits and release controls are unforgiving of part-time attention — but rarely justify a full-time executive before scale.
How hiring works
From first call to operating cadence in four steps
A COO hire should not take six months. This is the typical path to an embedded fractional COO in the UK.
Step 1
Introductory call (30 minutes)
Your stage, your team's shape and the outcome you need in the next two quarters. Usually enough to confirm whether fractional is the right model.
Step 2
Scoped proposal
A written scope: days per week, operating cadence, decision rights and commercial terms — day rate, retainer or outcome-linked.
Step 3
First week embedded
Structured onboarding: document review, stakeholder meetings, and the operating rhythm stood up by the end of week one.
Step 4
Operating cadence
1–3 embedded days per week with access between days. Weekly reviews, S&OP rhythm, and board-ready reporting from month one.

Common questions
Fractional COO UK — what buyers ask
- How much does a fractional COO cost in the UK?
- UK fractional COO day rates typically run £900–£1,200 depending on scope and sector. A 2-day-per-week engagement usually costs £7,800–£10,400 per month — against £150k–£250k+ fully loaded for a permanent hire.
- How quickly can a fractional COO start?
- Typically within 2–4 weeks of the first call, compared with 4–6 months to recruit, notice and onboard a permanent COO.
- Is fractional COO work inside or outside IR35?
- A genuine fractional engagement — multiple clients, control over how work is delivered, no mutuality of obligation — is typically outside IR35. The status question is addressed openly and documented at the start of every engagement.
- Do you work on-site or remotely?
- Both. UK-based engagements usually blend on-site days (line walks, reviews, supplier visits) with remote working between days. Based in the UK and available nationwide.
