When should you consider a fractional CMO instead of a full-time marketing hire?

By Natacha Cunningham, Thought Rebel · Last reviewed July 2026

In short it's actually very simple. You hire a fractional CMO when you need senior marketing direction more than daily output, whether you are an early-stage startup or an established business making a new play, and when you cannot yet justify a six-figure executive on the payroll. Hire someone full-time once marketing is a daily engine of the business, the work genuinely needs a person in the building, and you can cover the full annual cost, which in the UK starts north of £110,000 once you factor in more than just the salary.

Most founders and business owners do not have a marketing problem. They have a direction problem wearing a marketing costume. They are posting and running the odd campaign, but nobody senior owns the story, the positioning or the plan that ties spend to revenue. That is the gap a fractional CMO fills, and it is why the question is rarely "do we need marketing" and almost always "do we need it every day, or do we need it done right".

What a fractional CMO actually is

They're an experienced head of marketing that runs your marketing on a part-time basis, usually one to three days a week on a monthly retainer. You get the seniority, the strategy and the steady hand of someone who has done it before, without the salary, the equity and the permanence of a full-time hire. Not to mention saving you money from wasted initiatives and focusing precious budget on what you need to. Think of it as buying judgement by the day rather than by the year.

When a fractional CMO makes sense

• You are early stage and frantically doing everything at speed, but marketing needs the attention it deserves at this critical time as brand credibility is, well - everything!
• You are an established or smaller business making a new play, a pivot, a new market or a fresh push, and you want senior marketing on it without a permanent hire.
• The problem is direction and not volume. You need positioning, a plan and priorities, not another pair of hands posting daily. This is a quality over quantity stage.
• You have budget to create the work, but not to carry a £120,000-plus executive.
• You have a junior marketer or an agency doing things but nobody senior deciding which things to focus on.
• You are raising, or making a serious investment in growth, and want a credible go-to-market owned by someone who has done it.
• You want senior experience now, this quarter, not after a three-month search.

When to hire full-time instead

• Marketing is central to the business every single day, and the workload genuinely fills a full week.
• You need someone in the building, in the standups, in your hiring interviews - living and breathing the product and the culture in real time.
• You are past Series A, with revenue and runway to comfortably cover the full cost.
• The role is as much about building and managing a team as it is about strategy.
• The speed of internal decision-making matters more than the breadth of outside experience.

Plenty of companies start as a fractional team to set the direction, then hire full-time once the plan is proven and the work outgrows the days. A good fractional CMO will tell you when that moment has come, and often helps you hire their own replacement.

The cost TLDR

A full-time hire carries employer National Insurance, pension, recruitment fees and benefits on top. A fractional CMO is a straight retainer with none of that overhead, and you pay only for the days you use.

Fractional CMO ranges from £800 to £1,800 per day, or £4,000 to £12,000 per month. Two days a week is around £7,500 a month, roughly £90,000 a year. You get senior strategy and direction for the days you need it, no on-costs, live within weeks.

Full-time Marketing Director - Base around £65,000 to £95,000 (higher in London). True year-one cost is around £110,000 to £117,000 once on-costs are accounted for. You get a full-time owner in the building, plus the workload and management to justify it.

Full-time CMO - Base £120,000 to £250,000-plus, before on-costs. Executive leadership for a marketing-led business at scale.

Figures are typical UK ranges for 2026 and vary by sector, seniority and location based on my online research, so use it as a starting point, not a quote.

What a good fractional CMO should deliver in the first 90 days

Seniority is only worth paying for if you can see results around the 90-day mark. In the first three months you should expect a clear positioning and message the whole company can repeat, a costed marketing plan tied to revenue rather than vanity metrics, the two or three priorities that actually matter now, a few quick wins already in motion, and an honest view of the first hires or tools you need next. You should be able to see the direction and the early results, not just a strategy doc.

How to decide, in five questions

• Do you need marketing every day, or do you need it pointed in the right direction?
• Is the gap seniority and judgement, or hands and hours?
• Can you comfortably carry £110,000-plus a year, all in, for the next two years?
• Do you need results this quarter, or can you wait out a full executive search?
• Is this a strategy problem, or a build-and-manage-a-team problem?

If your answers lean towards direction, judgement, speed and strategy, start fractional. If they lean towards daily ownership, a full week of work and team building, hire full-time. When you are genuinely between the two, start fractional and let the work tell you when to commit.

Frequently asked questions

What is a fractional CMO?

I'm actually not a fan of the term Fractional CMO but it seems to be the most used term. An experienced marketing leader who runs your marketing part-time, usually one to three days a week on a monthly retainer. You get senior strategy and direction without the cost or commitment of a full-time executive.

How much does a fractional CMO cost in the UK?

Is a fractional CMO cheaper than a full-time CMO?

For early-stage companies, usually yes. A full-time marketing director or CMO costs around £110,000 a year, once salary, employer National Insurance, pension, recruitment, and benefits are accounted for. A fractional CMO gives you comparable seniority on the days you actually need it.

How long do fractional CMO contracts last?

Most run a minimum of three to twelve months, often starting more intensively to set direction, then easing to a lighter retainer as the plan takes hold. You also need to ensure you make yourself available to help get your fractional CMO up to speed quickly. Many end by design, when the work has grown enough to justify a full-time hire.

Can a fractional CMO help us raise?

Yes. A credible, costed go-to-market plan owned by someone who has done it before is exactly what investors want to see, and it is one of the most common reasons founders bring in a fractional CMO before a round.
