What is the difference between a fractional CXO and a consultant?

A fractional CXO is an embedded part-time executive. They attend your board or leadership meetings, carry ongoing accountability for outcomes, and work a fixed number of days per month on a 12-month commitment. A consultant delivers a defined piece of work with a start, an end and a written deliverable, then leaves. The consultant answers a question. The fractional executive shares the responsibility for acting on the answer.

How much does a fractional CXO cost in the UK?

UK fractional executive rates in 2026 typically run £1,000 to £1,500 per day. At Psychemeta a Fractional CXO engagement is £7,500 per month for 4 embedded days including board attendance and M&A advisory, and a Fractional CMO is £3,500 per month for 2 days. Compare that with £150,000 to £220,000 fully loaded for the equivalent full-time hire.

When is a strategy retainer better than a fractional executive?

When you need a thinking partner rather than an embedded doer. A monthly retainer (£1,500 per month at Psychemeta: a 90-minute monthly call, quarterly written brief and async support) suits owners who will do the executing themselves but want structured strategic counsel and an outside eye. If nobody inside the business can execute the strategy, a retainer will frustrate you and a fractional role fits better.

Can I start small before committing to a fractional executive?

Yes, and you usually should. The most common sequence we see: a one-day Advisory Day (£2,500) or a two-to-three week Diagnostic Sprint (£4,500) first, which tests the working relationship and produces a written deliverable you keep either way. If the fit is right, that work often converts into a retainer or fractional engagement, and you enter it knowing exactly how the advisor thinks.

Fractional CXO vs Consultancy vs Strategy Retainer: Which Do You Need?

Why this decision confuses almost everyone

I spent thirteen years inside the UK home care software industry, selling to and supporting hundreds of agencies, and the pattern repeated everywhere: an owner knows the business needs "strategic help", searches for it, and finds three completely different products all wearing the same label.

The confusion is not the buyer's fault. Consultancies deliberately blur the lines because ambiguity lets them upsell. So let me draw the lines sharply. Every credible strategic engagement in the UK market is one of three shapes:

Ongoing relationship. An advisor or fractional executive who stays. Monthly cadence, cumulative context, shared accountability. Minimum commitments of 6 to 12 months, because strategy compounds or it is theatre.
Bounded project. A defined question, a defined deliverable, a defined end. You keep the work product and owe nothing further.
Method installation. Not advice at all: an operating system for execution, installed in your team so the strategy you already have actually ships.

At Psychemeta these are three separate services with three separate pages: Strategic Advisory (ongoing), Business Consultancy (project) and 1:90 Align (method). The prices below are ours, but the framework works whoever you buy from.

Shape one: the ongoing relationship

This is the retainer-to-fractional spectrum, and the position on the spectrum is set by one variable: how embedded the advisor is.

Monthly strategy retainer, £1,500 a month. A 90-minute monthly call, a quarterly written strategic brief, async support between sessions. The advisor is a thinking partner. You do the executing. Six-month minimum, then rolling. This suits an owner who is capable of running the plays but wants a structured outside eye and someone to pressure-test decisions before they get expensive.

Fractional CMO, £3,500 a month. Two days a month embedded. Owns the marketing strategy, attends leadership meetings, carries marketing P&L oversight. This is no longer advice. It is a part-time executive who happens to also serve other clients. Twelve-month minimum, because an embedded role that leaves after a quarter does more damage than no role at all.

Fractional CXO, £7,500 a month. Four days a month, board attendance as an advisor, full strategy, operations and finance scope, M&A and exit advisory included. This is the substitute for a full-time executive you cannot yet justify. The fully-loaded cost of a real CXO in the UK runs £150,000 to £220,000 a year once you count NI, pension, equity and recruitment fees. Four embedded days at £90,000 a year buys most of the value at under half the cost, with none of the severance risk.

The honest constraint: fractional calendars are finite. We cap Fractional CXO at three concurrent clients because a fourth would degrade all three. Ask any fractional provider what their cap is. If they do not have one, the embedded days are aspiration, not commitment.

Shape two: the bounded project

Project consultancy exists for the buyer whose real thought is: I have one specific problem, I want an expert answer, and I do not want a subscription.

Advisory Day, £2,500. One full day on a single defined problem, materials reviewed in advance, a written brief within five working days, 30 days of async follow-up. The lowest-friction way to get senior thinking into the business, and, quietly, the best possible audition for any longer engagement.

Diagnostic Sprint, £4,500. Two to three weeks deep in one area: pricing, operations, recruitment economics, financial position, market entry. Output is a 15 to 25 page written report with four to seven prioritised recommendations ranked by effort against impact, plus a suggested 90-day execution plan and a leadership readout.

Consultancy Project, from £8,500. Multi-week, defined scope, defined deliverable: build the financial model, design the pricing architecture, plan the market entry, prepare for due diligence. Typical range £8,500 to £25,000 depending on scope. Weekly sponsor check-ins, working artefacts shared as they develop, board-ready summary at the end.

The defining feature of all three: you own everything. Models, analysis, board papers, all transferred as the work happens. When the project closes, the relationship owes nothing on either side. Many clients come back. None are contractually obliged to.

Shape three: the method installation

There is a third buyer the other two shapes fail. This owner does not need better strategy. They have a strategy. It stalls between the boardroom and the Monday morning task list, every quarter, predictably.

That is an execution problem, and you cannot fix an execution problem with more advice. You fix it with an operating system. 1:90 Align is ours: Arc, Wave, Milestone, Task, a 90-day planning cadence installed in the team through a workshop (£3,500), a full embedded implementation cycle (£8,500) or an ongoing retainer where we run the cadence for you (£2,500 a month).

The tell that you are this buyer: your last two annual plans were sensible and neither survived February.

The five-question framework

Work through these in order. Most businesses resolve to a clear answer by question three.

What shape is the problem? A specific question with a definable end is a project. An ongoing capability gap is a retainer or fractional role. A strategy that exists but never ships is a method problem. Name the shape before you look at a single price.
What commitment can you honour without resentment? Fractional roles need 12 months to pay back. Retainers need 6. Projects need only their own duration. A commitment you will resent by month three poisons the work. Buy shorter and upgrade.
Who has to own the outcome? If the external person must sit in your leadership meetings and share accountability for what happens next, that is fractional, and nothing cheaper will substitute. If your team owns the outcome and needs an expert answer to act on, a project is enough and a fractional role is overbuying.
What does it cost against the hire it replaces? Price strategic help against the fully-loaded alternative, never against zero. £7,500 a month sounds expensive until you price the £180,000 executive it replaces. £1,500 a month sounds expensive until you price one bad strategic decision taken without challenge.
What is the smallest honest test? When still unsure, buy the smallest engagement that genuinely tests the working relationship. An Advisory Day tells you more about an advisor in eight hours than any proposal, deck or testimonial page ever will. £2,500 is cheap information.

The costs, side by side

Advisory Day · £2,500 one-off · one day plus written brief · commitment: none
Diagnostic Sprint · £4,500 one-off · 2 to 3 weeks, 15 to 25 page report · commitment: none
Consultancy Project · £8,500 to £25,000 · multi-week, defined deliverable · commitment: the project
Strategy Retainer · £1,500 a month · monthly call, quarterly brief · commitment: 6 months
Fractional CMO · £3,500 a month · 2 embedded days · commitment: 12 months
Fractional CXO · £7,500 a month · 4 embedded days, board seat · commitment: 12 months
1:90 Align install · £3,500 to £8,500 one-off, or £2,500 a month embedded · commitment: one 90-day cycle

The sequences that actually work

In practice the three shapes are rarely either-or. The most successful engagements we run follow one of three sequences:

Test, then commit. Advisory Day → Diagnostic Sprint → Strategy Retainer or Fractional role. Each step is a genuine decision point. Nobody is locked in early, and by the time a 12-month fractional commitment is signed, both sides know precisely what they are getting.

Diagnose, then build. Diagnostic Sprint identifies what needs building → Consultancy Project builds it → the business runs it themselves. Total spend £13,000 to £30,000, no recurring cost, full ownership. Right for a business with a strong internal team and one hard problem.

Strategise, then systematise. Retainer or fractional engagement sets the direction → 1:90 Align installation makes the team ship it. This pairing exists because the most common failure mode of strategic advice, anyone's advice, is that it lands in a business with no execution cadence to receive it.

Three expensive mistakes

Buying a fractional executive to avoid making a decision. If the honest need is one hard call (sell or scale, pivot or persist), that is an Advisory Day and a weekend of thinking, not £90,000 a year of embedded days.
Buying a project when the problem is a capability gap. A brilliant pricing report handed to a team with nobody who owns pricing changes nothing. If there is no internal owner, buy the shape that includes one.
Buying advice when the problem is execution. The most common one. If good plans keep dying in the gap between the board and the team, the next consultant's plan will die there too. Fix the operating system first.
