Do I need a CTO for my small business?

Usually, no. If you run a business with 1 to 20 staff, what you're missing isn't a full-time executive on a six-figure salary — it's a few hours a month of senior technical judgement from someone who isn't trying to sell you anything. The rest of this page explains why, and is honest about the businesses where a real, full-time CTO genuinely is the right call.

What's actually missing#

You're the person who has to be everything for the business, and an expert in everything. Somewhere in the pile of decisions you make on no sleep, a run of technical ones keeps turning up: which accounting software to move to, whether that agency's quote for a new website is fair, whether your supplier's "we take security seriously" answer means anything, what to do about the AI tools everyone keeps mentioning.

None of these questions are hard for someone who does this for a living. They're hard for you because you don't have anyone whose job it is to answer them without an angle. Every vendor pitching you software, every agency quoting you a website, every consultant selling "AI transformation" has a reason to tell you yes. What's missing isn't more information — it's one person on your side who has no stake in the answer.

This is also why the questions never really go away. You can Google your way to a defensible answer on any one of them given enough evenings. What you can't get from a search engine is someone who remembers the answer you settled on last time, knows how your systems actually fit together, and will tell you when a new decision contradicts an old one.

That gap is real, and it's common. Government research into UK business AI adoption found that 71% of businesses cite "no identified need" as the reason they haven't adopted AI — but the qualitative interviews behind that figure tell a different story: businesses that struggle to picture where AI would actually help, not businesses that have genuinely concluded they don't need it (DSIT, AI Adoption Research, 2026). "No identified need" is very often "nobody whose job it is to identify it."

What a technical leader actually does at this size#

Strip away the job title and the work is specific and recurring:

• Vendor and quote judgement. Is this software the right tool, or the one the salesperson pushed hardest? Is this development quote reasonable for the work described?
• Tooling and system decisions. What you run your business on, and whether to change it, made by someone who has seen the alternative fail elsewhere.
• Security posture. Not "are we secure" as a yes/no, but which risks are worth fixing this quarter and which are noise.
• Continuity. What happens if the one person who understands your systems leaves, and whether you'd notice the gap before it became a crisis.
• AI judgement calls. Which tools are worth a serious look, which are noise, and what a sensible policy on using them with client data looks like.

That's a real job. It is not, for most businesses this size, a full-time one.

What a full-time CTO actually costs#

The median advertised salary for a Chief Technology Officer in the UK was £100,000 a year, based on vacancies posted in the six months to 25 August 2026 (ITJobsWatch). That's salary only — add employer National Insurance, pension contributions, equipment, and the cost of actually finding and hiring the right person, and the real annual cost sits well above the headline figure.

For that money you get one person, full-time, employed. Most 1 to 20 staff businesses don't have enough technical decision-making to fill a working week — they have a steady trickle of decisions that need judgement, not a job that needs filling. Paying full-time-executive money for a few hours a month of actual demand is the expensive way to answer the question.

There's also the hiring itself to account for: recruiting at this level takes months, a bad hire costs you the salary and the lost time, and a good one will get bored running a technology function sized for one person a fraction of the week. None of that shows up in the headline salary figure, and all of it is avoided by paying for judgement in the quantity you actually use. We've written a fuller breakdown of what the fractional and outsourced options cost by comparison in how much a fractional CTO costs in the UK.

When you genuinely need a full-time CTO#

Some businesses do need one, and telling you otherwise would be bad advice dressed up as a sales pitch. A full-time CTO is the right answer when:

• Technology is the product. You sell software, an app, or a platform, and technical decisions are made daily, not monthly.
• You have an in-house development team. Someone needs to manage, mentor and be accountable for engineers day to day. That's a management job, not an advisory one, and it doesn't work part-time.
• Technical risk is existential, not occasional. If a bad technical call could sink the business by next quarter rather than cost you a wasted contract, you need someone in the room every day, not once a month.

If that's your business, go and hire properly — a fractional or outsourced arrangement will under-serve you, and no amount of good advice from us changes that. The rest of this page is for everyone else.

The middle option#

For most owner-managed businesses, the answer sits between "nobody" and "a full-time executive": one senior person who owns your technology decisions, vendor relationships, security posture and continuity, on an advisory retainer sized to how much judgement you actually need — not a headcount you have to justify every month. It's the same category of role as a fractional or virtual CTO, described in language that fits how UK owner-managed businesses actually talk about the problem: an outsourced IT director.

In practice that means someone who is available when a decision comes up — a supplier contract to check, a security question from an auditor or a customer, a call on whether a piece of software is worth the money — rather than someone you have to keep permanently busy to justify. It's advisory first: the aim is that you make better decisions faster, not that you hand the decisions over.

If you're still weighing this against simply hiring someone permanently, or splitting the work between an IT support contract and someone who handles decisions, that comparison is covered in full in should I hire an IT person or outsource?

FAQ#

Isn't this just a fractional CTO with a different name? Functionally, yes — same category of role, described in the vocabulary UK owner-managed businesses actually use rather than the US-imported "fractional CTO" label most providers borrow from venture-funded start-ups.

We already pay an IT support company. Isn't that covered? Usually not. Most IT support contracts cover keeping things running — helpdesk tickets, break-fix, patching. Almost none of them cover deciding what you should be running in the first place, or telling you honestly when a supplier's quote or a new tool isn't worth it. Those are different jobs, and the gap between them is exactly where this sits.

How much does it cost? It's sized to what you need rather than sold as a fixed package — an advisory retainer, not a salary. The full cost picture, including what comparable providers publish, is in how much a fractional CTO costs in the UK.
