The agency

What interim management firms actually do

Every claim on a card links to the page that states it; anything a firm does not publish about itself is left out. If you would rather brief one firm, we come back with a shortlist of 3–5, each with rate, availability and IR35 position set out.

Interim management firms supply experienced managers and executives for a fixed term, to fill a gap, lead a change or see a transaction through. The specialist providers keep a network of interims and match them to the brief; the Institute of Interim Management and the Interim Management Association are the bodies the field organises around.

This page lists interim management providers. Interim executive search firms lists the search firms’ interim arms; interim management agency is our own service.

The firms below are interim executive firms, profiles rather than a ranking: no firm here publishes the audited outcomes a league table would need, and we are one of the firms.

The scope

How to choose between interim management firms

The fee basis, in writing. Retained search firms are paid in staged instalments whatever the outcome, and work exclusively; contingent recruiters are paid only if their candidate is hired, often non-exclusively; interim and fractional providers usually charge through the day rate or a retainer. Ask for the basis and when each payment falls due, in writing. We publish no fees: ours are agreed in writing per engagement.

Who vets, and how. Ask who runs the search day to day — at a retained firm, the partner who wins the brief is not always the person who calls candidates — and what each candidate is tested on beyond the CV. Our five-stage vetting is published.

What comes back. Named candidates with a rate or salary, availability and an IR35 position — or a database, a longlist or a marketplace to browse? Ours is a shortlist of 3–5.

IR35 on every brief. For an interim or fractional executive working through their own company, the off-payroll rules decide how the engagement is taxed, and a medium or large client makes the status determination (HMRC). Ask for the IR35 position on the brief, not after the contract.

Retained, contingent or day rate. Retained search for a permanent, board-level appointment; contingency for a role below the board with many candidates; interim for full-time cover for a fixed term; fractional for senior judgement on part of the week.

The process

How does a brief become a shortlist?

The decision

Which of the interim management firms fits your brief

Match the firm to the hire, not the other way round.

  • TurnaroundA business under pressureA provider with interims who have led turnaround and crisis mandates.
  • IntegrationAfter a dealAn interim who has run post-deal integration or separation.
  • A specialismIT, finance or HRA provider with a practice in the function — several on this page name theirs.

Vetting

How do we vet an executive?

Five stages before anyone reaches a shortlist of three to five.

  1. Pedigree screen
    Tenure
    We verify prior tenure in the seat, at the scale and stage you need. No consultant presenting as an executive.
  2. Mandate fit
    Fit
    Fit to your stage, sector and the problem the seat exists to solve, not a CV keyword.
  3. Reference deep-dive
    Verify
    We take references ourselves, from recent clients and boards: what they delivered, not what they titled it.
  4. Shortlist
    Shortlist
    Three to five candidates, each with day rate, availability and IR35 position set out.
  5. Kick-off
    Start
    Scope, first-month outcomes and the contract agreed before day one.

The full process is on how we vet.

which kind of firm

Interim management firms: which kind of firm fits and which page to read next

The interim management firms above work in the models set out in the comparison table — retained search, contingent recruitment, interim provision and fractional provision — and several work in more than one. Start with the hire: permanent or a phase, board level or below, five days or part of the week. Then ask each firm which model it proposes for your brief, and why.

If you would rather brief one firm for every shape of the seat, book a call: we recruit fractional, interim, part-time and permanent executives, and the brief decides the shape.

Whichever you brief, the same law applies: the Employment Agencies Act and the Conduct Regulations cover executive search consultants as well as agencies, a firm must not charge a candidate for finding them work, and the fee you pay is a commercial agreement between you and the firm (gov.uk guidance on the Conduct Regulations).

method

How this list is built and what it is not

Own-site facts only. Each firm is profiled from its own website, read on 23 October 2026, or from a primary register such as Companies House; every claim links to the page that states it. We do not repeat a firm’s fees, guarantees, client names or self-descriptions such as “leading” or “number one”.

Not a ranking. Numbers show position on the page. No firm here publishes the audited outcomes a ranking would need, and we are one of the firms — listed first because the page is ours.

Independence. Fractional Quest takes no referral fees from any firm listed, and none of them is a partner or client. Other interim management firms exist; we add a firm only when its own site gives us facts to state.

The right route

Agency, recruiter, interim or permanent?

Three taps. Say how much senior work there is, for how long, and whether it is one leader or a run of hires; the tool names the route.

What do you need?
How much senior work each week?
For how long?
The route · Fractional executive

Brief a fractional recruitment agency.

Senior judgement for part of the week: a fractional CFO, CTO, CMO or COO on one to three days. We come back with a shortlist of three to five, each with day rate, availability and IR35 position set out.

We recruit executives. We don’t supply embedded fractional recruiters; where that is the right route, the tool says so.
