What’s the realistic timeline for a senior executive search?

By Adrian Lawrence FCA, Founder, Exec Capital

A practical question that comes up early in most senior search conversations: how long does the search actually take from start to finish? The honest answer is that a substantive senior search runs 12-18 weeks from formal mandate to offer-acceptance, with the candidate’s notice period adding a further 3-6 months before the new senior leader is in role. The compound timetable from \”we’ve decided to hire\” to \”the new senior leader is in seat\” is therefore typically 6-9 months.

This post sets out the realistic phase-by-phase timetable, the dimensions that drive variance, and how firms can plan senior succession with the realistic timeline in view rather than the optimistic version.

The phase-by-phase timetable

Brief and pre-mandate work: 1-3 weeks. Substantive conversations between firm and search firm, brief development, success criteria, candidate-pool framing. For complex appointments (CEO, Chair, particularly senior CFO), this phase substantively shapes the search and warrants more time than firms instinctively give it.

Market mapping and pipeline development: 3-5 weeks. Substantive market mapping across the relevant candidate pool, initial outreach and engagement, calibration of the pipeline against the brief.

Candidate engagement and assessment: 4-6 weeks. Substantive conversations with engaged candidates, structured assessment, presentation of long-list and short-list to the firm, second-round and (where relevant) third-round interviews.

Reference work and offer-stage: 2-4 weeks. Formal references on the preferred candidate, substantive offer construction, negotiation of terms including compensation structuring (which can be substantive — see our Executive Compensation Guide), and offer-acceptance.

Notice period: 3-6 months for senior candidates. Notice periods at the senior end are typically 6 months for executives at most listed firms and large private firms, 3 months at smaller firms or for candidates earlier in their senior career.

Compound timetable from formal search-launch to senior leader in role: 26-40 weeks (6-9 months). For FCA-regulated firms, add the SMF approval timeline (see our post on FCA SMF approval timetables).

Dimensions that drive variance

Five things substantially extend or compress the timetable. Specificity of the brief — substantive briefs with clear success criteria run faster than generic briefs that require iteration. Tightness of the candidate pool — appointments where the pool is genuinely tight (Chief AI Officer, certain sector specialists) take longer at the engagement stage because reaching enough candidates requires more touches. Geographic dimensions — appointments where international candidates are in scope add time for relocation discussion and (where applicable) visa work. Compensation complexity — appointments with substantive equity and deferral structures take longer at offer-stage because the structuring conversation is substantive. Regulatory dimensions — FCA-regulated and other supervised appointments add the approval timeline as set out above.

Practical planning implications

The pattern that works in practice is to plan senior succession with the full timetable in view from the start. For non-regulated firms, this typically means starting substantive succession conversations 9-12 months before the target start date for the new senior leader; for regulated firms, 12-15 months. Where the departure is forced (resignation, dismissal, illness), the timetable compresses but the substantive work doesn’t — firms in this situation typically run interim arrangements for the search period and accept the compound timetable.
