Hire a fractional CTO in the UK
A fractional CTO owns technical direction without being the person writing most of the code. They decide architecture, hire and manage engineers, and translate between the product you want and what it will actually take to build.
A fractional CTO in the UK charges £800–£1,400 a day as of 2026, typically one to three days a week, according to the getoperators day-rate dataset.
What does a fractional CTO do?
- Architecture and the technology choices you will live with for years
- Hiring engineers, and telling you honestly whether an agency is the better answer
- Security, reliability and the risks nobody raises until they happen
- Roadmap feasibility: what can ship by when, and what that will cost
- Managing an outsourced development team so somebody senior is checking the work
When do you need a fractional CTO?
- You are a non-technical founder relying entirely on an agency you cannot evaluate
- Your product works but every change takes longer than the last one
- You are about to raise and investors will ask who owns the technology
- Two engineers are making architecture decisions with nobody above them
How much does a fractional CTO cost in the UK?
Higher end for regulated sectors, AI systems and technical due diligence.
Rates are set by the operator and paid to them directly.
Where in the UK can you hire a fractional CTO?
Demand centres on London and the Cambridge and Oxford deep-tech clusters, with Manchester and Edinburgh close behind. Fractional CTO work is the most remote-friendly seat on the bench: most engagements are remote with an on-site day around planning or hiring.
The seat written up city by city, with who on the bench is based there: fractional CTO in London.
What does a fractional CTO cost in each city?
The day rate moves with the market, and so does the paperwork behind the engagement. CTO in London (£800 to £1,400), CTO in Manchester (£650 to £1,150), CTO in Birmingham (£650 to £1,150), CTO in Edinburgh (£650 to £1,150), CTO in New York ($1,200 to $2,200), CTO in San Francisco ($1,400 to $2,800) and CTO in Dubai (AED 3,500 to AED 7,000). Every one of those is a day rate for the seat held one to three days a week, with the full-time comparison beside it.
Outside the UK this seat runs $1,000 to $2,000 a day in the US and AED 3,500 to AED 7,000 a day in the UAE.
Is a fractional CTO worth it against a full-time hire?
A development agency builds what you ask for and has no incentive to tell you the request is wrong. A senior engineer is excellent at building and rarely wants to hire, manage and sit with investors. A full-time CTO is £130k to £190k plus meaningful equity. A fractional CTO gives you the judgement layer and can manage whoever is already building.
The longer version is on fractional vs interim vs full-time.

How do you choose a fractional CTO?
- They should be comfortable saying an idea is not worth building
- Ask about a system they inherited and had to fix, not just ones they started
- Whether they have hired engineers, since that is often the real work
- Someone who explains trade-offs in business terms rather than tooling

Common questions about hiring a fractional CTO
What is a fractional CTO?
A fractional CTO is an experienced technology leader who owns your architecture, technical hiring and build decisions part-time, usually one to three days a week. The real job, done by someone who has shipped before, without the full-time cost.
What does a fractional CTO cost in the UK?
Typically £800 to £1,400 a day. Many companies use one to two days a week, roughly £3,500 to £11,000 a month. Regulated sectors, AI systems and technical due diligence work sit at the higher end.
Can a fractional CTO work with my existing development agency?
Yes, and it is one of the most common reasons to hire one. They give you somebody senior and independent reviewing the agency's work, scope and estimates, which usually pays for itself quickly.
Do fractional CTOs write code?
Some do, most do not do it as the main job. You are buying architecture, hiring and judgement. If what you actually need is someone to build the product, you want senior engineers, and a good fractional CTO will tell you that.
When does a startup need a fractional CTO?
Usually when technical decisions start having commercial consequences and there is nobody senior making them: a non-technical founder with an agency, a small team with no technical leadership, or a raise where investors will ask who owns the technology.
Do I pay getoperators anything to book one?
Browsing the bench and booking direct needs only a company account. We only charge if you ask us to run the search for you.
Do you cover Cambridge and the deep-tech clusters?
Yes. Fractional CTO demand concentrates in London, Cambridge and Oxford, and the seat is the most remote-friendly on the bench, so an operator can serve a Cambridge lab or a Manchester scale-up equally well.
The questions that are not about this seat, on contracts, notice, IR35 and how a booking works, are answered on the fractional executive FAQ.
