What a fractional CISO costs in the UK

A fractional CISO in the UK costs £900 to £1,500 a day in 2026 (about £113 to £188 an hour on an 8-hour day), which is £3,450 to £5,750 a month at one day a week and £6,900 to £11,500 at two.

Rates checked 1 November 2026. Bands come from the getoperators bench, not a third party.

Two days a week runs £82,800 to £138,000 a year, according to the getoperators day-rate dataset, with no employer costs on top. That is £9,200 a month at the mid-band £1,200 day rate, as of 2026. What it comes to at other day counts, and how it compares with the full-time version of the same seat once employer costs are counted, is below.

Monthly figures are the annual cost spread evenly, based on 46 billable weeks a year rather than 52, because operators take holidays too. The mid-band column is the arithmetic midpoint of the published band, not a typical rate.

What is the fractional CISO hourly rate?

About £113 to £188 an hour in the UK in 2026, which is the published day rate divided by an 8-hour day. The mid-band works out at £150 an hour.

UK operators quote by the day because senior work gets finished in days rather than hours, and an hourly contract pays for presence rather than for the decision. The same conversion for every other seat is on fractional executive hourly rates for every seat.

Day rate, retainer or hourly: which to agree

They are the same price written three ways. A monthly retainer is the day rate times the days agreed in a month, so two days a week of a fractional CISO is a retainer of £6,900 to £11,500 a month across the band. An hourly figure is the day rate divided by 8, and is useful for comparing quotes rather than for buying.

Whichever unit goes on the invoice, put three things in writing: the days a month the fee buys, the notice either side gives to end or change it, and the response time between days. A retainer with no day count attached is the one arrangement where both sides can agree something and be wrong about what.

Against the full-time version of the same seat

A full-time CISO in a UK company of this size sits around £140,000. That is not what they cost.

Base salary assumed£140,000
Employer National Insurance 15% above £5,000£20,250
Pension statutory minimum, capped£1,321
Recruitment fee 20%, one-off£28,000
First year, all in£189,571

Where it stops being cheaper

At £1,200 a day, a fractional CISO and a full-time one cost the same at about 3.4 days a week. Below that, fractional wins on cost and on speed. Above it, you are paying full-time money for part-time attention, and you should hire somebody. When that is the answer, we find full-time executives too, with the fee on the page.

That is the honest edge of this. Work it through for your own numbers in the cost calculator, which will tell you the same thing.

How this band compares with other published UK figures

The other figures measure different things: advertised contract roles of every seniority, or interim assignments across all functions. They are a cross-check on the band, not a substitute for it.

What the day rate does not include

VAT, if the operator is registered, which most are. Travel and expenses for on-site days, agreed before they start. Nothing else: no employer National Insurance, no pension, no holiday or sick pay, no equipment and no notice period to buy out. Our own fee is separate from the rate: If a company engages an operator it was introduced to here, it pays getoperators a fee of 15% of the engagement's value over its first twelve months, with a minimum of £3,500 ($4,800 in the United States, AED 17,500 in the UAE), under its Terms of Business. Nothing is added to or taken from the operator's rate.

Employment status is worth a word. A genuine fractional arrangement usually involves real independence, several clients and control over how the work is done, but status depends on the facts of each engagement rather than the label on it. Take proper advice rather than relying on a word. This is general information, not tax advice.

Common questions

What is a fractional CISO's hourly rate in the UK?

About £113 to £188 an hour in 2026, which is the published day rate of £900 to £1,500 divided by an 8-hour day. UK operators quote by the day rather than the hour, so treat the hourly figure as a way to compare quotes rather than a way to buy.

How much does a fractional CISO cost per month in the UK?

A fractional CISO charges £900 to £1,500 a day. At the mid-band £1,200, two days a week works out at about £9,200 a month. One day a week is roughly £4,600, and half a day a week about £2,300. There are no employer costs on top, because you pay the operator directly.

Is a fractional CISO cheaper than hiring one full-time?

Up to about 3.4 days a week, yes. A full-time CISO on £140,000 costs roughly £189,571 in the first year once employer National Insurance, pension and a recruitment fee are counted. Past that break-even the full-time hire is better value and gets you five days rather than two.

What does the day rate not include?

VAT if the operator is registered, which most are. Travel and expenses for on-site days, agreed in advance. And nothing else: no employer National Insurance, no pension contribution, no holiday or sick pay, no equipment, and no notice period to buy out.

Is a monthly retainer for a fractional CISO the same as a day rate?

It is the same price expressed differently. A retainer is the day rate times the days agreed in a month, so two days a week of a fractional CISO at £900 to £1,500 a day is a retainer of £6,900 to £11,500 a month. What makes it work is writing down the days it buys, the notice either side gives and how quickly the operator responds between days.

What moves a fractional CISO to the top of the band?

Among the highest fractional rates, driven by certification work and regulated sectors.

Where these numbers come from

The band is the one published for every seat on the 2026 UK day rates page, where the method is stated and the data is free to download. The employer costs are current statutory UK rates. The salary and the recruitment fee are assumptions, marked as such, and both are set where they make the fractional side look worse rather than better.
