TL;DR
A fractional CMO in the UK typically costs £800 to £1,800 a day, or £3,000 to £12,000 a month on retainer, depending on days and seniority. Light advisory retainers start from around £500 a month. For that you mostly get strategy and direction. If nobody in the business can do the work, budget for delivery on top.
Why trust this page: I sell a hands-on monthly marketing subscription, so I've got an interest here and I'll say plainly where I'm not the right fit. I haven't held a CMO title. Every price below links to where it came from, and the provider figures are labelled as such.
Day rates vs retainers vs advisory
Most UK fractional CMOs charge a day rate of about £800 to £1,800, or a monthly retainer of about £3,000 to £12,000. That range comes from a UK consultant's cost guide, which also puts very senior people at £2,000 to £3,500 a day or more. Few firms publish fixed prices, so treat these as ranges, not a market survey. There are three common ways to pay.
- Day rate. You buy a set number of days each month. One provider, fractionalcmo.uk, publishes £900 a day for one or two days a month, £850 for three to seven, and £800 for eight or more, plus expenses. That's the provider's own price list.
- Monthly retainer. A flat fee for an agreed amount of time. The same UK guide puts two to four days a week at £3,000 to £8,000 a month for typical UK businesses, and starter engagements of one or two days a month at £1,500 to £3,000, with slower progress as the trade-off.
- Advisory. Lighter touch: a monthly check-in or a workshop. fractionalcmo.uk lists retainers from £500 a month and workshops with written findings from £1,200.
Watch the minimum term. The guide gives the example of a £5,000 monthly quote with a three to six month minimum, which is really a £15,000 to £30,000 commitment.
What drives the price
- Days a month. The biggest lever. More days usually means a lower day rate but a bigger bill.
- Seniority and track record. Someone who has led marketing at a known brand or through funding rounds charges at the top of the range.
- Hands-on work. The UK guide says execution, as opposed to strategy only, costs 30 to 60% more. That's one commentator's figure, not a survey.
- Team management and sector. Running staff or agencies, or working in a regulated industry, pushes the price up.
- What's excluded. Fees usually exclude ad spend, freelancers and design. The same guide suggests £200 to £800 a month for tools and software.
What you get for the money
A fractional CMO is a senior marketer working part-time. Typically they set the plan, own the budget, hire and manage agencies or staff, and report to the founder or board. The value is judgement: what to do, what to stop, and who should do it.
What you usually don't get is the doing. Most direct a team rather than building the website, writing the emails or setting up the CRM themselves. That's fine if the team exists. It's a problem if it doesn't.
The hidden cost: direction without delivery
This is the cost nobody puts on the rate card. If there's nobody to delegate to, you pay for direction and then pay again for delivery.
Here's a rough example using the published figures above. Three days a month at £850 is £2,550. A single-channel agency retainer for SEO, PPC or social typically runs £1,250 to £3,500 a month, according to agency-side research from Whito (indicative, excluding VAT and ad spend). Together that's roughly £3,800 to £6,050 a month, and that covers one channel. Full-service agency retainers in the same research run £3,500 to £16,750 a month.
Compared with hiring in-house
The usual alternative is a hire. Using Ashdown Group's 2026 salary guide, a marketing manager on the national median of £56,950 costs about £66,060 a year once you add 15% employer National Insurance above the £5,000 threshold (£7,793) and the 3% minimum pension on qualifying earnings (£1,321). That's about £5,505 a month before software, training and recruitment fees.
A marketing executive on the median £35,046 costs about £40,420 a year, or £3,368 a month, on the same basis. Rates are from GOV.UK's 2026 to 2027 employer thresholds and the workplace pension rules. Small employers may be able to offset some NI with the Employment Allowance. The full working is on in-house vs outsourced marketing.
So a fractional CMO on a few days a month usually costs less than a senior hire. But an executive does work, while a fractional CMO mostly directs it. Compare like with like.
When it's worth it, and when a hands-on subscription fits better
A fractional CMO is worth the money when:
- you already have a marketing team, or agencies, that need leading;
- you're managing a big budget or several channels at once;
- you need someone senior in board meetings or in front of investors.
If that's you, hire an experienced fractional CMO. I'm not the right fit. I haven't held a CMO title, and I don't run large marketing departments or sit on boards.
A hands-on subscription tends to fit better when there's no team, and the gap is getting things built: the website, the follow-up, the CRM, one channel at a time. That's what I sell. Plans are £995, £1,950 or £3,950 a month, month to month, with unlimited requests worked one at a time (two at a time on the top plan). If you only want advice, a strategy call is £125 an hour. The trade-off is real: it's one person and a queue, not a team, so it won't suit you if you need paid ads at volume, PR, or lots of work happening at once. Prices are on the pricing page, and there's a fuller side-by-side on fractional CMO vs agency vs freelancer.
Questions to ask before you hire a fractional CMO
- How many days a month, and what happens in them? Get it in writing.
- What will you build yourself, and what will you delegate? If the answer is "delegate", ask to whom, and who pays.
- What's not included? Ad spend, tools, design, freelancers, expenses.
- What's the minimum term and notice period? Multiply the monthly fee by the minimum to see the real commitment.
- What will exist after 90 days? A plan is a start. Ask what will be live.
- Who owns the accounts and the work? Ad accounts, CRM, website and files should be in your name.
- Can I speak to a client at a business my size? Experience leading a 40-person team doesn't always translate to a five-person firm.
The practical summary
Budget £800 to £1,800 a day, or £3,000 to £12,000 a month, for a UK fractional CMO, plus whatever it costs to get the work done. If you have a team to lead, that's money well spent. If you don't, price the delivery first, then decide whether you need direction, hands, or both.

Fair questions
How much does a fractional CMO cost per day in the UK?
Published UK day rates commonly sit between about £800 and £1,800. One UK guide puts very senior people, such as former heads of marketing at known brands, at £2,000 to £3,500 or more. One provider publishes £800 to £900 a day, with the lower rate for more days a month.
How much is a fractional CMO retainer a month?
Most UK figures fall between about £3,000 and £12,000 a month, depending on how many days you buy and how senior the person is. Light starter engagements of one or two days a month can be £1,500 to £3,000. Ad spend, freelancers and design are usually extra.
Is a fractional CMO cheaper than a marketing manager?
Often, yes. A UK marketing manager on the national median salary costs about £66,000 a year once employer NI and minimum pension are added, around £5,500 a month before tools. A fractional CMO on two to four days a month usually costs less, but you may still need someone to do the work.
Does a fractional CMO do the work themselves?
Usually not much of it. Most set the plan, own the budget and direct staff or agencies. One UK guide says hands-on execution costs 30 to 60% more than strategy-only work. Ask exactly what they will build themselves before you sign.
What's the alternative to a fractional CMO for a small business?
If you have no team to lead, consider someone who plans and delivers: a hands-on marketing subscription, a freelancer for one job, or an agency for one channel. I sell a monthly subscription from £995, so weigh that, but if you need board-level leadership of a big team, hire a fractional CMO.
