A fractional CMO sets strategy and directs others. An agency delivers through a team, usually on a retainer. A freelancer does one skill well. For a small business without a marketing team, the gap is usually the doing, not the strategy, so pick whoever will actually ship the work you need first.
| Compared | Fractional CMO | Marketing agency | Freelancer | Hands-on subscription (me) |
|---|---|---|---|---|
| Main job | Strategy, budget, leading others | Delivery through a team | One skill, delivered | Plan and delivery by one person |
| Typical UK cost | £800–£1,800 a day; retainers often £3,000–£12,000 a month | Single channel about £1,250–£3,500 a month; multi-channel higher | Hourly or per project, varies widely | £995–£3,950 a month |
| Does the work | Rarely | Yes, via account team | Yes, in their lane | Yes |
| Commitment | Monthly retainer or days | Often 6–12 months | Per project | Month to month |
| Best when | You have a team to lead | You need scale or many channels | You need one job done | You need several jobs done, joined up |

A fractional CMO is a senior marketer who works part-time, often a few days a month. They set the plan, own the budget, hire and manage agencies or staff, and report to the founder or board.
They’re strongest when there are people to lead. If there’s nobody to delegate to, you pay for direction and then pay again for delivery.
Published UK day rates commonly sit between about £800 and £1,800, with monthly retainers from about £3,000 up to £12,000 depending on days and seniority. Some providers offer lighter advisory retainers from around £500.
Few firms publish fixed prices, so treat these as ranges from providers and commentators rather than a market survey.
Agency-side research puts single-channel retainers (SEO, PPC or social) at roughly £1,250 to £3,500 a month, with multi-channel retainers higher. Ad management is often charged as a percentage of spend on top.
Agencies suit businesses that need volume or specialist channels. Watch for long minimum terms and junior staff doing the work.
When you know exactly what you need and it’s one skill: a website, a set of ads, an email sequence. The risk comes when you need several freelancers and become the project manager joining them up.
At that size most businesses don’t have a marketing team for a fractional CMO to lead, and can’t justify a multi-channel agency retainer. What usually moves the needle is getting the website, follow-up and CRM working, then one channel at a time.
That’s the gap a hands-on subscription fills. If you already have a team, a fractional CMO is the stronger choice.
Senior direction is the missing piece.
Specialists and capacity.
Cheapest route to one outcome.
One person ships the joined-up work.
I sell a monthly marketing subscription, so I’ve included it as an option and said plainly where it isn’t the right fit.

I'll search you the way your buyers do and tell you what I find. If I can help, I'll say which plan and why. If I can't, I'll say that too.
