How to become a fractional Head of Growth
A fractional Head of Growth in the UK charges £600 to £1,100 a day and holds two to three clients at once. What follows is the arithmetic on that, the honest ceiling, and the cases where this seat does not work part-time at all.
Fractional Head of Growth salary: what the year adds up to
Day rate × days a week × 46 billable weeks, rather than 52, because you will take holidays and because a year of unbroken client work is not a thing that happens. The rates are the band for the seat on the 2026 day rates page.
| Day rate | 1 day a week | 2 days a week | 3 days a week |
|---|---|---|---|
| Starting out£600 a day | £27,600a year | £55,200a year | £82,800a year |
| Established£850 a day | £39,100a year | £78,200a year | £117,300a year |
| Top of the band£1,100 a day | £50,600a year | £101,200a year | £151,800a year |
Before tax, before your own costs, and assuming the days are actually sold. Most people starting out spend a good part of the first year at fewer days than they planned.
What moves you up the band
Higher end for marketplaces, subscription products and anything with a complex funnel.
How many clients the seat holds
Two to three. Growth work is experimental and the experiments need watching, which means the days are less compressible than they look on paper.
How to get your first fractional Head of Growth clients
Usually a company already spending on acquisition without knowing what is working. The diagnosis is the sale, and it is one you can often make from outside before anybody pays you.
The diagnosis is portable. A short written account of what the funnel showed at the first client, with the numbers, is the strongest thing to send the second, and investors with several companies spending on acquisition are the quickest route to more.
Where fractional Head of Growth roles come from
From companies already spending on acquisition and unsure what is working, usually through an investor or another fractional leader. The roles that are advertised tend to be channel jobs with a growth title.
Do you need a qualification or a certificate?
The track record is the credential. Platform certificates show you can run a channel; a company engaging a fractional growth lead wants evidence you moved a number across the whole funnel.
It needs a funnel already owned end to end, with acquisition and retention both in scope and a budget behind them. A channel specialist in paid media or SEO is a valuable freelancer; the growth seat is deciding where the problem actually is.
What the work actually is
Owning the whole funnel rather than the top of it, and being willing to say the problem is retention when everybody wanted to hear it was ads.
When this seat does not work fractionally
- There is no data and no willingness to instrument any.
- They want a channel specialist and are using the word growth to mean paid media.
- The economics do not work at any volume, which no amount of optimisation fixes.
What people get wrong
- Accepting a target you do not control the inputs for.
- Being measured on a metric that moves for reasons unrelated to your work.
- Taking the seat where the real gap is a marketing leader.
The mechanics, briefly
Most UK fractional executives work through their own limited company and invoice per day or on a monthly retainer. Professional indemnity cover is worth having before the first engagement rather than after. Check what your last employment contract says about notice and restrictions before you start approaching anybody, particularly if a first client might be somebody you met there.
Employment status is the question that worries people most, and it is worth understanding properly rather than assuming: IR35 and fractional executives covers who decides, what gets tested, and the directorship point that catches people out.
