The four routes
| Route | What you get | Typical cost | Watch for |
|---|---|---|---|
| An agency's fractional offering | A strategist attached to the agency | Often bundled into a retainer | Whether they can recommend less agency work |
| A freelance consultant | One person, independent, chosen by you | £700 to £1,300 a day | Strategy without anybody to execute it |
| A marketplace or bench | Verified people you contact directly | £700 to £1,300 a day, paid to them | Whether placement can be bought |
| Your own network | Somebody you already trust | Whatever you agree | A limited pool, and a hard process to run fairly |
The conflict worth naming
An agency-supplied fractional CMO is a real service and some are genuinely good. The structural issue is that the person advising on where your budget goes works for an organisation that receives some of it.
Most of the time this is invisible, because the advice and the interest point the same way. It becomes visible at exactly the moment you most need independence: when the right answer is to cut a channel the agency delivers, bring something in house, or spend less overall.
If you take this route, ask directly what happens when the recommendation is to reduce spend with them, and get the answer before you start rather than during the argument.
What a fractional CMO owns, and what they do not
- They own positioning, the plan, where budget goes and what it is expected to return, the measurement, and the marketing team if there is one.
- They do not own execution. At one or two days a week nobody is writing copy, running campaigns or managing a channel day to day.
- This is the mistake most companies make with this seat: hiring the leadership and leaving nobody to do the work. The output is a strategy nobody implements, and the seat gets blamed.
What it costs
Independently, a fractional CMO charges £700 to £1,300 a day, with the upper end for category creation, rebrands and full funnel rebuilds. One day a week is roughly thirty-two to sixty thousand pounds a year, and two days is double that.
Through an agency the number is usually inside a larger retainer, which makes it look cheaper and makes it harder to see what you are paying for the leadership as opposed to the delivery. Ask for it separated.
Choosing between candidates
Fractional CMO on its own is not a qualification, because several hundred people use the title. The useful signal is specificity: the stage, the motion and the sector.
Somebody who has rebuilt demand generation for B2B software at Series A is a different hire from somebody who has run brand for consumer retail, and both will describe themselves the same way. Ask what they have done at your stage, in your motion, and what the number did afterwards.
Questions
- How much do fractional CMO services cost?
- Independently the seat runs around £700 to £1,300 a day, so one day a week lands roughly between thirty-two and sixty thousand pounds a year. Through an agency it is usually bundled into a retainer, which is worth asking to have separated so you can see what the leadership itself costs.
- Is an agency fractional CMO a conflict of interest?
- Structurally yes, though it is often harmless in practice. The person advising where budget goes works for an organisation receiving some of it. It matters at the moment the right answer is to spend less with them, which is precisely when independent advice is most valuable.
- Does a fractional CMO do the marketing work?
- No. They own the plan, the budget, the measurement and the team. At one or two days a week there is no capacity to execute, so somebody has to do the work underneath them. Hiring the seat with nobody to execute is the most common way this engagement fails.
