Fractional or Interim Chief Growth Officer?
This is the cleanest of the three distinctions, and it turns on the business need rather than the title. One is event-driven. The other is stage-driven. Here is how to tell which you have, and what each costs in the UK.
Event-driven or stage-driven
An interim CGO is commonly used during leadership transitions, transformation periods, or situations requiring temporary high-intensity executive support. Something happened, and the seat needs filling properly while it is resolved. The engagement is fixed-term and usually close to full-time.
A fractional CGO is commonly structured as recurring part-time leadership support with agreed review points and exit conditions. Nothing has gone wrong; the company has reached a stage where growth needs senior ownership it cannot yet justify full-time.
Buyers confuse the two for understandable reasons. Both involve external senior leadership, both are non-permanent, and both are strategic and operational at once. The question that separates them is simply whether you are covering a gap or building a capability.
| Interim CGO | Fractional CGO | |
|---|---|---|
| Trigger | Leadership vacancy, transformation, restructuring, business transition, urgent executive support | The company has reached a stage where growth needs senior ownership |
| Shape | Fixed-term, higher-intensity involvement, commonly close to full-time | Recurring part-time engagement with agreed review points and exit conditions |
| Primary aim | Hold and stabilize the function through a defined period | Build ongoing growth capability inside the team |
| Commercial basis | Day rate over a defined term | Monthly retainer |
What each costs in the UK
These are market figures. Scope is calibrated on a first call.
Interim CGO
£1,000 to £2,000/day
Senior interim growth and marketing executives commonly fall in this range, with complex mandates going higher. For context on the wider market, the Institute of Interim Management's 2025 survey puts the average interim executive day rate at £894, rising to £970 in the private sector and £947 outside IR35. By company type, scale-ups tend to sit at £800 to £1,400, mid-market and private-equity-backed at £1,200 to £2,000, B2B technology at £1,000 to £1,800, and large enterprises at £1,800 to £3,000 or above.

Fractional CGO
£4,000 to £9,000/month
UK market range at one to two days a week. More complex or private-equity-backed mandates can exceed £14,000 a month. The monthly cost is lower than an interim because the intensity is lower and the horizon is longer.

One test that usually settles it
Ask what happens at the end. If the answer is “we hire someone permanent and they take over,” you are describing an interim engagement, and you should buy one. If the answer is “the team keeps running the motion,” that is a capability-building brief, which is what the fractional shape is for.
A fractional engagement can leave a durable growth system behind, which is usually the most durable thing on offer. It depends on the team having the capacity and alignment to carry it, so it is a potential outcome to work toward, not something anyone should promise you up front.
The way I work is simple. Three parts.
Operate
I work inside your team, operating the growth function week to week. Holding a seat until someone permanent arrives is a different job.
First result
A concrete growth outcome inside the engagement window, on a number we agree at the start.
Hand back
A repeatable motion your team runs without me, with review points and exit conditions agreed in advance.
Questions people ask
We have an urgent vacancy. Is fractional a fit?
Usually not, and I would say so on the call. A vacancy that needs covering at intensity is an interim brief. Buying fractional for an interim problem tends to leave both sides frustrated.
Can an interim engagement become fractional?
It happens, and it can work well: high intensity through the transition, then a lighter recurring arrangement once the permanent structure is in place. Worth agreeing the step-down in advance rather than negotiating it while tired.
Is fractional just a cheaper interim?
No, and treating it that way is the common mistake. It is a different intensity aimed at a different outcome. If you need the interim outcome, the lower monthly figure is a false economy.
How is the end of a fractional engagement handled?
Through review points and exit conditions agreed at the start, so neither side is guessing. An engagement with no defined exit is a warning sign whichever model you choose.
Covering a gap, or building a capability?
If you are not sure which one you have, that is usually a thirty-minute conversation. If you would rather start with a number than a call, the diagnostic scores seven pillars of your growth surface and shows you the weakest one.
