By Jonny Ross, Fractional CMO.
The short version
- Most UK fractional CMO engagements land between £3,000 and £10,000 plus VAT a month. Mine start at £4,500 plus VAT for three days a month.
- Almost every published UK figure traces back to a provider’s own marketing page, and several of them cite each other. No independent survey of fractional CMO rates exists.
- The one properly sampled dataset is the Institute of Interim Management’s annual survey. In 2026 it measured fractional working for the first time and found nearly a quarter of last assignments were delivered that way.
- The day rate is the least useful number in the conversation. How many days you buy, and what those days get spent on, decides whether it was expensive.

How much does a fractional CMO cost in the UK?
Most UK fractional CMO engagements sit between £3,000 and £10,000 plus VAT a month, on a day rate somewhere between about £800 and £1,500 plus VAT. That is the honest range, and I have hedged it deliberately. In a moment I will show you why a tidier answer would be a made-up one.
My own seats start at £4,500 plus VAT a month for three days, which is the standard shape, on a day rate of £1,500 plus VAT. There is a two-day advisory seat below that at £3,000, and a five-day embedded seat above it at £7,500. Those are floors rather than a price list, and I would rather quote you properly once I understand the problem.
If you only wanted the number, that is the number. The rest of this page is about why the number on its own will not help you decide anything.
Why are the published numbers so unreliable?
Because almost all of them are marketing, dressed as measurement.
I went looking for the source behind the figures that come up when you search this question. What I found was a closed loop. One placement firm publishes a rate table citing its own unpublished interviews. A second cites a recruiter’s salary guide. A third cites the first two. Follow any of them far enough and you arrive at somebody’s content page, never at a survey with a sample size and a method attached.
Those ranges are probably somewhere near reality, because the people repeating them are quoting real work. But a range that has been passed around until it hardened is a market impression, and building a budget on one is uncomfortable when every party publishing it has an interest in where it lands.
“Nearly a quarter of last assignments were delivered fractionally. We will track the importance of fractional working in coming years.”
Institute of Interim Management, Interim Management Survey Report 2026, June 2026, the first edition to measure fractional working
There is a straightforward reason no proper survey exists. The category is young. The interim management profession has been measuring itself annually since 2010, and fractional working only appeared in that survey as a question this year.
Worth being precise about
Fractional, interim and part-time are three different purchases
Interim is one business, full-time, for a fixed period. Somebody steps into a vacant seat while you recruit, or carries a specific programme, and when it is done they leave. The 2026 survey puts the average assignment at 10 months.
Fractional is several businesses at once, ongoing, at a few days a month each. Nobody is holding a seat open for a permanent hire. The arrangement is the arrangement.
The difference matters commercially, because interim is priced to end and fractional is priced to continue. If a provider quotes you an interim day rate for a fractional seat, one of you has misunderstood what is being bought.
What does the real data say?
The only UK dataset with a disclosed method behind it is the Institute of Interim Management’s annual survey, now in its seventeenth edition. It covers interim management across all functions rather than marketing specifically, so treat it as the shape of the market, not a quote for your engagement.
£1,004
is the average private sector interim day rate in 2026, up 3.5% on the year and the first time it has passed a thousand pounds. The all-sector average is £907, held down by public sector work at £700.
Institute of Interim Management, Interim Management Survey Report 2026, 17th edition, June 2026
Three other figures from the same report are worth having in your head. Assignments now average 10 months, up from 9.6. Interims billed an average of 148 days across the year, up from 133. And work outside IR35 pays £949 a day against £830 inside it, a gap of about 14% that has narrowed sharply as inside-IR35 rates caught up.
What the report does not contain is a marketing breakdown. Its functional splits are IT, finance, HR, operations and strategy. So when a page tells you the IIM says fractional CMOs charge a particular rate, that page has not read the survey.
What should you compare it against?
Compare it against the alternatives you would actually consider. That is where the arithmetic gets interesting.
| Route | What it actually costs | Time to useful | Where it goes wrong |
|---|---|---|---|
| Full-time marketing director Permanent hire |
Salary, plus 15% employer NI on everything above £5,000, plus 3% minimum pension, plus a search fee of 20% to 35% of the first year For: businesses with enough marketing to fill five days a week |
Three to six months to hire, then a quarter to land | You buy one person’s ceiling. If they are wrong, you find out in month nine and start again |
| Interim Full-time, fixed term |
About £1,004 a day in the private sector, roughly £20,000 a month at full utilisation For: a vacancy to cover or a programme to land |
Two to four weeks | Priced to end. Ten months in, the thinking leaves with them |
| Fractional CMO Two to five days a month, ongoing |
£3,000 to £10,000 plus VAT a month. No NI, no pension, no search fee, no notice period beyond the contract For: businesses that need the judgement more often than they need the hands |
Two to four weeks | Buy too few days and you get opinions instead of momentum |
| Agency retainer, on its own Delivery without a senior seat above it |
Whatever the retainer is. A good agency is usually the cheapest way to get work done well For: businesses whose strategy is already settled and who own the brief |
Immediate | An agency answers the brief it is given. Somebody on your side still has to own whether it was the right brief |
Interim day rate from the Institute of Interim Management, June 2026. Employer NI rate and threshold from HMRC guidance for 2026 to 2027. Pension minimum from the auto-enrolment thresholds confirmed for 2026 to 2027. Search fee range is the market band published by UK executive search firms rather than a survey figure. On a phone, scroll the table sideways.
I have deliberately left the salary out of the top row. The salary guides that would give me one are recruiter marketing with no disclosed sample, and I am not going to do to you what the rate pages did to me.
What I can give you is the multiplier. Whatever salary you are quoted, add 15% on everything above £5,000 for employer National Insurance, add at least 3% for pension, and add a one-off search fee somewhere between 20% and 35% of the first year’s package. A £90,000 hire is not a £90,000 decision. It is comfortably over £120,000 in year one, and it takes three months minimum to reverse.
So the question worth answering is not whether £4,500 a month is a lot of money. It is what £4,500 a month buys you next to the thing you would otherwise do with it.
What actually drives the cost?
The day rate is the least useful variable in the conversation. What moves the real number is how many days you buy, and it moves it more than most buyers expect, because two days a month and five days a month are different jobs, not one job at two intensities. Two days buys judgement: someone who reads the numbers, challenges the plan and holds the strategy steady while everyone else is busy. Five days buys judgement plus capacity, and it starts to look like a marketing function with a head on it.
Underneath that sits the question nobody quotes on, which is what the days actually get spent on. This is the capacity-before-demand argument applied to your own leadership team. If the constraint in the business is not marketing, then buying marketing days at any rate is buying the wrong thing, and the seat earns its money by finding that out early, before the spend goes anywhere.
Then there is altitude. A fractional CMO sitting in the leadership team, seeing the numbers before the board does, is a different purchase from one who receives a brief and responds to it. The rate is frequently identical. The return is not.
Four questions to ask before you agree a number
- What would you need to see in our numbers before you told us to stop spending? A good answer names a metric. A weak one reassures you.
- Which meetings will you be in? If the answer is only marketing meetings, you are buying a consultant, not a seat.
- What happens in the first 90 days, specifically? Vague onboarding is the tell that the days have not been thought about.
- How many other clients do you hold, and on which days? Fractional works because it is shared. It stops working when it is oversubscribed.
Why does my own pricing land where it does?
Three seats, on a day rate of £1,500 plus VAT throughout. An advisory seat at two days a month, from £3,000 plus VAT. A fractional CMO seat at three days a month, from £4,500 plus VAT, which is where most engagements settle. An embedded seat at five or more days a month, from £7,500 plus VAT.
I changed those numbers this month, and the reason is worth putting in public because it is the same argument this whole page is making. My previous floor was £2,500 plus VAT a month based on two days. Run the arithmetic on that and it comes out at £1,250 a day, which was below my own published rate for a single standalone consultancy day and identical to what I charge for a one-off clarity session. The most committed thing a client could buy was the cheapest thing on the rate card. Nobody had divided the retainer by the days, so it went unnoticed for years.
The move to three days as the standard came from the same review. Two days a month is enough to have an opinion and not quite enough to change anything, because the month has a rhythm and a seat that appears once a fortnight keeps arriving after the decision has been taken. Three days is where the seat is in the room beforehand.
The strongest evidence I have for what continuity is worth comes from DCS, a Leeds cloud hosting and disaster recovery business I have advised continuously since 2011, through three ownership eras including a private equity acquisition in 2025 that the relationship came through intact. Fifteen years of compounding context is a different asset from fifteen years of billable days, and it is the thing an engagement priced to end can never accumulate. My work with Hometree, a private-equity-backed home energy group, is the other end of the same argument, and the numbers behind it sit on that page.
Common questions
Is a fractional CMO cheaper than hiring one?
Per month, almost always. Per day, no. You pay a premium day rate for a fraction of the days and come out ahead because you were never going to fill five days a week with decisions that needed that seniority. If you genuinely have five days a week of senior marketing decisions, hire someone.
Do fractional CMOs charge VAT?
Most do, because most are over the registration threshold. If you are VAT registered it washes through. If you are not, add 20% to every figure on this page and judge it on that.
What is the minimum sensible commitment?
Two days a month, and I would want six. Anything shorter and you are buying an audit with a longer delivery date. The interim survey puts the average assignment at 10 months, and fractional seats generally run longer, because they are not priced to end.
Does IR35 affect what I pay?
It affects what the fractional CMO takes home, which affects what they quote. The 2026 survey has inside-IR35 work at £830 a day against £949 outside, so the status of the engagement is a real input into the number. Settle it before you agree the rate.
Why do the published ranges vary so much?
Because they describe different jobs. Someone running a strategy day once a month and someone sitting in an SLT through an acquisition are not the same purchase, and the market has not yet agreed on language that separates them.
Is fractional CMO training worth doing if I want to become one?
Different question, and I have written the long answer separately in what fractional CMO training actually covers. The short version is that the craft is real and the certificates are not.
The next step
If you are weighing this up, the useful conversation is about how many days the problem actually needs and what those days would be spent on. That usually takes about fifteen minutes to work out, and it occasionally ends with me telling you that you do not need a seat yet.

Employer National Insurance rate and threshold are from HMRC’s rates and thresholds for employers 2026 to 2027. Auto-enrolment pension minimums are the 2026 to 2027 thresholds confirmed by written ministerial statement in December 2025. The executive search fee range is the band published by UK executive search firms and is market commentary rather than survey data, labelled as such above. The £3,000 to £10,000 monthly range is a market impression drawn from published UK provider pages, which is the limitation described in the second section. Provider pages checked 30 July 2026.
