Fractional CIO services give you a senior IT and systems leader on a defined weekly commitment — the engagements we scope run one to three days a week — instead of a full-time hire. Exec Capital publishes an interim CIO day rate of £800–£2,000, against a full-time UK CIO median salary of £150,250 (Robert Half).
This page sets out what the service covers, where the CIO seat ends and the CTO seat begins, what it costs and when it beats an IT managed-service provider or a permanent hire.
A fractional CIO service puts a senior information and systems leader into your business on an ongoing commitment.
The CIO owns how the company runs internally on technology — core systems, data, IT operations, vendors and security posture — at the weekly commitment agreed, priced as a monthly retainer.
For context, Exec Capital observes that fractional technology leadership typically runs two to four days a week and suits businesses in the £3m–£25m revenue range (FACTS 272).
Where the CIO seat ends and the CTO seat begins. A CIO owns the systems the business runs *on*: ERP, finance and HR platforms, data architecture, networks, endpoints, identity, and the vendor estate.
A CTO owns the systems the business *sells*: the product, the engineering organisation and the technical roadmap.
Buyers frequently search for both together, and companies without a product engineering function usually need a CIO even when they ask for a CTO.
If the question is about the product, Fractional CTO Services is the right page.
The scope is leadership and governance, not helpdesk.
A fractional CIO sets the systems roadmap, runs vendor and licence negotiations, owns the data strategy, is accountable for security and continuity at board level, and decides what gets built, bought or outsourced.
Day-to-day support and infrastructure operations belong with your internal IT team or a managed-service provider.
If you are hiring rather than buying a service, the Fractional CIO Jobs UK hub covers hiring, Interim CIO Jobs UK carries interim mandates, and Fractional CIO Hourly Rate has the rate conversions.
Systems strategy and roadmap. What gets built, bought or outsourced, and in what order — including the ERP, finance and HR platform decisions that are hard to reverse. Data architecture and governance — where data lives, who can see it, and whether the reporting layer can be trusted. Security, continuity and compliance owned at board level. Vendor and licence management — the estate, the contracts and the renewal leverage. Post-merger systems integration.
Helpdesk, endpoint support, network operations and day-to-day infrastructure administration.
That is an internal IT team or a managed-service provider, and it costs a fraction of a CIO day rate.
The CIO owns the systems you run on.
The CTO owns the product you sell.
The CISO owns security as a discipline in its own right — a separate seat once regulation, certification or customer security review makes it a full-time concern.
A fractional CIO can carry the security brief until a CISO is genuinely warranted.
The systems you run on, or the product you sell. That one question routes almost every CIO-or-CTO brief correctly.
⚠ No UK benchmark publishes a FRACTIONAL CIO day rate — the published band is for INTERIM CIOs. Rather than invent one, the weekly figures below are the midpoint of Exec Capital’s interim CIO band of £800–£2,000, i.e. £1,400, multiplied by days per week (FACTS 203). Treat them as an indication drawn from the adjacent market, not as a published fractional rate.
Every figure below is published by the named source. Exec Capital (FACTS 203) publishes the interim day rate and the CIO salary tiers; Robert Half (FACTS 203) publishes the salary percentiles. Financial services and critical infrastructure command a premium. Nothing here is a derivation.
| Benchmark | Published figure | Source |
|---|---|---|
| Interim CIO day rate | £800–£2,000 | Exec Capital (203) |
| Mid-market CIO salary | £100,000–£180,000 | Exec Capital (203) |
| Large corporate / regulated CIO | £200,000–£350,000+ | Exec Capital (203) |
| UK CIO salary, 25th percentile | £108,000 | Robert Half (203) |
| UK CIO salary, median | £150,250 | Robert Half (203) |
| UK CIO salary, 75th percentile | £200,000 | Robert Half (203) |
The three ways a UK company buys senior IT and systems leadership, on the dimensions that decide between them.
| Metric | Fractional CIO service | Managed service provider | Full-time CIO hire |
|---|---|---|---|
| Typical UK cost | Day rate × days a week, on retainer | Per-seat or per-device monthly fee | £150,250 median salary plus employer costs |
| What you get | Strategy, governance, vendor leverage | Support, monitoring and infrastructure operations | All of the above, full-time |
| Whose side they are on | Yours — they select and review the MSP | Theirs — they sell their own service | Yours |
| Time to start | Shortlist in two working days is the target | An onboarding period for the estate | A full search, start to finish |
| Best when | The estate needs decisions and an owner | The estate needs running day to day | The seat is full-time work |
| Exit | Notice period, or convert to core | Contract end | Redundancy or resignation |
Three situations where the service shape beats both a managed-service provider and a permanent hire.
A core platform decision you cannot easily reverse and nobody internally has made one before. The cost of getting it wrong dwarfs the cost of the engagement.
The estate has grown by departmental purchase, the reporting layer contradicts itself, and licence renewals arrive unchallenged. Two days a week buys a map, a plan and vendor leverage.
An enterprise customer, an insurer or a regulator is about to test your controls. A CIO who has been through it structures the answer instead of improvising it.
Five stages: qualification, mandate fit, reference deep-dive, shortlist and analysis, kick-off. Our fee is 12% of engagement value and is only triggered when you sign — the shortlist costs nothing if you do not hire.
How we take a founder or board's brief and turn it into a delivery system across core, fractional, network, and outsourced functions.
CONFIRM — REAL PROCESSStage · pressure · the work nobody is doing.
We run The Team Architect on every brief. Stage, headcount, sector, pressure. The output is the org shape we'd build with you — including the seats to hold for now. We turn briefs down here, gracefully, when the answer is 'not yet'.
Core. Fractional. Network. Outsourced.
Each function gets a verdict and an intensity. Engineering core. Finance fractional at 2.5 d/wk. Paid-media on the network. IT helpdesk outsourced. We commit to days, IR35 status, and replacement terms in writing before search starts.
Network-first. Outbound where it needs to be.
Fractional candidates have portfolios, not job alerts. We run from our own network plus a structured outbound for the senior end. Shortlist in 8–12 days. Honest scoring against the rubric — no padding.
First-week plan. Success criteria. IR35 live.
Calibration calls. Onboarding plan written down. IR35 structure live before day one. We sit in the first cross-functional meeting if it helps. The replacement guarantee runs for 90 days.
Quarterly cadence. Bridge to core when right.
Monthly check-ins for the first quarter, quarterly after. We surface when a fractional should convert to core (Series A → Series B finance is the modal moment) and we own the bridge. Replacement, conversion, off-ramp — it's all the same firm.
