01/ definition

What is an interim CTO?

An interim CTO is the Chief Technology Officer, full-time, for a fixed term. Not an adviser and not a part-time fractional CTO: the person who runs technology until the job is done or the permanent hire arrives.

01 · cadence

The CTO seat, five days a week.

An interim CTO takes the role in full — the engineering team, the architecture, the roadmap and the budget — rather than advising from outside it.

5 daysa week, typically

02/ scope

06/ tax

Is an interim CTO tax-deductible?

General position under UK rules, with the HMRC source for each point. Not tax advice — check your own case with your accountant.

01 · DEDUCTIBLE

The fees are a business expense

An interim CTO’s fees, like a salary, are deductible against profits when incurred wholly and exclusively for the trade (HMRC BIM37000). At the 25% main rate, each £1,000 of fees costs a profitable company £750 after relief.

02 · EMPLOYER NI

Employer NI follows IR35 status

A permanent CTO carries employer National Insurance at 15% (gov.uk). An interim engaged through their own company carries none when the engagement is outside IR35; inside IR35, the fee-payer deducts tax and NI and pays employer NI. Status depends on how the engagement runs in practice.

03 · WHO DECIDES

IR35 status, by company size

Medium and large clients determine the interim’s status themselves; for a small private-sector client, the interim’s own company decides (HMRC off-payroll guidance).

07/ decision

When to hire an interim CTO

Four situations where companies hire an interim CTO rather than wait for a permanent one — and where most interim CTO jobs come from.

Which sounds like you?

A resignation, a founder stepping back or a performance exit leaves the seat empty and the team without direction.

  • → Hold the roadmap
  • → Keep the team
  • → Run the permanent search

Outages, runaway cloud cost, a stalled migration or a security incident that needs a senior owner now.

  • → Stabilise first
  • → Fix the root cause
  • → Report to the board

Technical due diligence, post-acquisition integration or getting the story straight before a funding round.

  • → DD readiness
  • → Integration plan
  • → Investor confidence

A replatform, an AI build or a regulatory deadline that the current team cannot lead alone.

  • → Defined outcome
  • → Fixed term
  • → Clean handover

08/ guide

Hiring an interim CTO: what to get right

Start with the outcome, not the title. An interim CTO is hired to leave something behind — a stable platform, a rebuilt team, a finished migration, a clean due-diligence pack. Write that into the brief with a date, and the right candidates select themselves; leave it vague and you will be comparing CVs rather than approaches.

Decide between interim and fractional early. If the work needs a full-time owner for a few months, hire an interim CTO. If it needs senior judgement a day or two a week for the foreseeable future, a fractional CTO is cheaper and steadier. Companies searching for an “interim fractional CTO” are usually weighing the two; both are possible, but price and scope them separately.

Budget from the published bands. Exec Capital’s 2026 guide puts interim CTO day rates at £800–£1,800. At five days a week that is £16,800–£37,800 a month, and a six-month assignment runs roughly £104,000–£234,000 — our arithmetic. A permanent Chief Technology Officer is a median £160,500 base (Robert Half) before employer National Insurance, pension, equity and a retained search fee of 25–35%.

Check the track record against your situation. An interim CTO who has run a platform migration at a Series B company is a different hire from one who has held the seat through a trade sale. Ask for two references from the last three assignments and speak to them yourself; we do the same before anyone reaches a shortlist.

Plan the handover on day one. The best interim Chief Technology Officers work to make themselves unnecessary: documenting decisions, developing the engineering leads and, often, helping you hire their permanent successor. If you are looking for interim CTO jobs rather than hiring, the live board below lists current interim CTO roles, and fractional CTO jobs cover the part-time market.

08.1/ temporary cto

Temporary CTO: what to hand over, and what to hold

A temporary CTO, or temporary Chief Technology Officer, is an interim CTO by another name: full-time, for a fixed term, with authority over the engineering team, the architecture and the technology budget. The Institute of Interim Management defines interim management as leadership by a board or near-board level executive “over a finite time span”, and separates it from a contractor’s contract or an agency worker’s temporary work (IIM guide to interim management). If you need someone to write code or deliver one project, that is a contract hire; if you need the seat held, it is a temporary CTO.

The first job is usually to stop things slipping: releases, incidents, supplier renewals and security. Two government baselines make that concrete. Cyber Essentials, the minimum standard the government recommends and the NCSC developed, covers firewalls, secure configuration, security updates, user access control and malware protection. The voluntary Software Security Code of Practice sets out what software vendors are expected to do about the security and resilience of what they ship. A temporary CTO should be able to tell the board where the business stands against both.

If the need is ongoing and part-time rather than a full-time gap, a part-time CTO or a fractional CTO fits better. For a temporary CTO, we send a shortlist of three to five with day rate, availability and IR35 position set out.

08.2/ temporary cto hiring

Temporary CTO hiring: set the term and the handover

Most temporary CTO hiring starts from one of three situations: a CTO has left and the permanent search will take time, a departure is coming and you want cover in place, or a programme — a migration, a rebuild, a due diligence process — needs a senior owner for as long as it runs. In each case “temporary” means interim: the whole seat, full-time, for a defined period.

Set the term by the outcome rather than the calendar. Write down what must be true at the end — the platform stable, the migration live, a permanent CTO in post — and agree a review point part-way through. Put the handover in the brief as well: who the temporary CTO hands to, what gets documented, and whether they help recruit and induct their successor. The Institute of Interim Management treats the exit, including knowledge transfer and sourcing successors, as a stage of the assignment in its own right (IIM guide to interim management).

On the contract, a temporary CTO is engaged either as a fixed-term employee, whose contract ends on a set date or when a specific task is done, or as a contractor through their own limited company. For a contractor, IR35 status depends on how the engagement runs in practice, and medium and large clients make the determination (HMRC off-payroll guidance).

08.3/ interim chief technology officer

Interim Chief Technology Officer: assess the level, not the title

The title interim Chief Technology Officer covers a wide range of people, from engineering managers who held the title at a small company to executives who have run technology for a board. The SFIA framework is a useful yardstick: its highest level of responsibility describes someone who “determines overall organisational vision and strategy, and assumes accountability for overall success”. Ask candidates for evidence at that level — decisions they owned, budgets they held, what they reported to a board.

Test the board side as well as the technical side. The NCSC’s Cyber Security Toolkit for Boards includes questions a board should ask about cyber security; a strong interim Chief Technology Officer can answer them in plain language. Structure the interviews, too: the CIPD’s guidance on selection methods favours structured, panel-scored interviews and work-sample tasks, and for a CTO a review of your architecture or incident history works well.

IR35 for an interim CTO depends on how the assignment runs in practice; medium and large clients make the status determination, and HMRC’s CEST tool gives HMRC’s view of a specific engagement. If the role is really about the systems that run the business rather than the product it sells, see hiring an interim CIO.

09/ contract

Interim CTO jobs: how the assignment is contracted

Interim CTO jobs are usually contracted through the interim’s own limited company, on a fixed-term agreement that sets out the scope, the term, the day rate, the days a week and notice on each side. The scope is the outcome from the brief: the migration, the rebuild or the handover the assignment exists to deliver.

IR35 status turns on how the assignment runs in practice, not on what the contract calls it. HMRC looks at substitution, control and whether either side must offer or accept further work. Medium and large clients make the status determination; for a small private-sector client, the interim’s own company does (HMRC off-payroll guidance). See the IR35 guide.

Interim CTO FAQ

Hiring an interim Chief Technology Officer, or looking for interim CTO jobs.

An interim CTO is a full-time Chief Technology Officer on a fixed-term assignment, usually three to twelve months, who runs technology through a vacancy, a crisis or a defined programme and then hands over.

Yes — that is what this is. We find and shortlist an interim CTO for your brief; the interim works for you, full-time, for the term. Interim CTO services for growth companies and PE-backed businesses follow the same brief.

Send us a brief: the situation, the outcome you need by the end of the term and your start date. We aim to send a shortlist of three to five interim CTOs, each with day rate, availability and IR35 position set out. You interview and choose.

Exec Capital’s 2026 guide puts interim CTO day rates at £800–£1,800. At five days a week that is £16,800–£37,800 a month, or roughly £104,000–£234,000 for six months (our arithmetic).

An interim CTO works full-time for a fixed term. A fractional CTO works one to three days a week on an ongoing basis — £1,000–£1,600 a day or £3,000–£7,000 a month. Interim for a gap or a programme; fractional for steady part-time leadership.

You send a brief; we send a shortlist of three to five interim CTOs, each with day rate, availability and IR35 position set out. You interview and choose, and the start date depends on the chosen interim’s availability.

When the CTO seat is empty, the platform needs a senior owner now, a deal or funding round needs technical leadership, or a programme has a hard deadline the current team cannot lead alone.

Hire interim CTO cover when the seat cannot stay empty while a permanent search runs: a team without direction, a platform that needs an owner, or a deal on a timetable. Many companies do both — the interim holds the seat and helps hire the successor. We take permanent CTO briefs as well as interim ones, and each ends in a shortlist of three to five, with day rate or pay, availability and IR35 position set out.

We do not rank individual interims, and no published list reliably does. The ones worth shortlisting have led an integration before: merging two engineering teams, deciding which platform survives, consolidating cloud accounts and vendor contracts, and keeping both products running while it happens. Ask each candidate for the integration they led, what they decided first and why, and a reference from the acquirer’s side. Brief us with the deal timetable and we send a shortlist of three to five.

Sometimes, if both sides want it. Agree any conversion terms at the start so the option exists without surprises.

It depends on how the assignment runs in practice, not on what the contract calls it. HMRC looks at substitution, control and mutuality of obligation. Medium and large clients make the status determination; for a small private-sector client, the interim’s own company does (HMRC).

A temporary CTO is an interim Chief Technology Officer: full-time for a fixed term, with authority over engineering, architecture and the technology budget, handing over to a permanent CTO at the end. It differs from a contract CTO hired to deliver one project; the Institute of Interim Management draws the same line between interim management and contractor work.

Against the level of the role and your situation. The SFIA levels of responsibility help separate strategy-setting leaders from senior engineers, and the CIPD recommends structured interviews and work-sample tasks. Every candidate we shortlist goes through the five stages on our vetting page.

Agree three things first: the outcome that ends the term, who the temporary CTO hands over to, and the contract — a fixed-term employment contract or a contract with the CTO’s own limited company, where IR35 status depends on how the engagement runs in practice. Then send us the brief: we send a shortlist of three to five interim CTOs with day rate, availability and IR35 position set out.
