How to Hire a CEO: A Complete Guide for UK Companies

Hiring a CEO is the most consequential appointment a board makes. The decision shapes the firm’s strategy, its culture, its commercial trajectory, and the way it weathers the next five to ten years. It is also the appointment where the gap between what looks like the right candidate at offer stage and how that candidate performs in role is widest — partly because the role is genuinely hard to assess from outside it, partly because boards under-specify what they actually need, and partly because the CEO market is one where the strongest candidates are evaluating the firm as carefully as the firm is evaluating them. Boards that approach a CEO search the way they would approach a senior executive hire one rung down typically end up with a different outcome than boards that approach it deliberately, with the time and seriousness the role warrants.

This guide is written for chairs, founders, nomination committees and major shareholders working through CEO succession. It sets out what a CEO appointment actually involves: when to start, how to build the role specification, what the candidate pool looks like at different stages of company development, how the search process should run, how to structure compensation and incentives, and what the first hundred days look like for the new CEO. It draws on our work running CEO searches for owner-managed and PE-backed businesses, scale-ups, mid-market firms, and corporate subsidiaries across the UK. For the corporate (non-regulated) CEO appointment we run, see our CEO recruitment service page; for CEO appointments in FCA-regulated firms specifically, see our SMF1 CEO hiring guide.

When to start a CEO search

The single most important decision in a CEO search is when to start it, and most boards start later than they should. The realistic timeline for a CEO appointment — from the decision to begin succession to the new CEO’s first day — runs to twenty to thirty weeks. Searches that begin only when the firm urgently needs a new CEO routinely compress this timeline, with predictable consequences: the candidate pool is narrower because the strongest candidates are not actively seeking moves, the negotiation runs harder because the firm is on the back foot, and the onboarding is rushed because the previous CEO has already left.

The healthier rhythm is to begin succession planning two to three years before the existing CEO is expected to leave. This does not mean running a continuous search for that period — it means having an explicit succession plan, identifying potential internal candidates who could be developed into the role, mapping the external candidate market periodically, and having an established relationship with a search firm that knows the business well enough to mobilise quickly when the formal search begins.

For boards facing imminent CEO succession without that prior work, the question becomes how to manage the gap between what the timeline ideally would look like and what the situation actually allows. Two practical responses help. The first is to engage a search firm before the role is formally announced, so the early candidate identification work is happening in the background while the board is finalising the role specification. The second is to plan for an interim arrangement — typically a member of the existing executive team or an experienced interim CEO — covering the period between the previous CEO’s departure and the new CEO’s first day. Boards that have not planned for this often end up making the wrong appointment because the pressure to fill the seat overwhelms the rigour of the assessment.

Building the role specification

The role specification is the document that frames every conversation with every candidate. It should answer four questions clearly, and most specifications do well on the first two and badly on the second two.

What does the firm need this CEO to deliver? The commercial brief — strategic priorities, growth targets, transformation needs, market positioning. This is where most existing specifications already do good work because it is the question the board has spent the most time thinking about.

What does the firm look like under this CEO in three to five years? The forward picture — what scale the firm is operating at, what the executive team looks like, what the firm is known for, what the relationship with shareholders looks like. Specifications that articulate this clearly attract candidates who can engage with the trajectory, not just the current state.

What is the relationship with the chair and the board? This is where specifications most consistently underdeliver. The relationship between the CEO and the chair is the most important working relationship in the firm, and it is the relationship most likely to generate friction if it is not deliberately structured at the start of an appointment. Specifications that handle this well describe how the chair sees the CEO role, how often they expect to meet, what they expect the chair-CEO discussion to focus on, and what the boundaries are between chair territory and CEO territory.

What does the firm not need from this CEO? The negative specification — the things the previous CEO did that the next CEO should not, or the priorities the board has explicitly de-emphasised. Strong candidates probe this question carefully, and specifications that are honest about the negative dimension carry more credibility than specifications that present the role only in positive terms.

The strongest specifications also address the firm’s current state honestly — including any matters that the new CEO will need to handle in the first year. Recent regulatory matters, executive team weaknesses, customer or commercial issues, technology debt, succession gaps elsewhere on the senior team. Candidates who discover these in the first ninety days having not been told about them in the search rarely respond well; candidates who are told about them upfront and decide to take the role anyway are bringing genuine commitment to the work.

The candidate pool: who is genuinely available

The CEO candidate pool varies enormously by company size, sector and ownership structure. Five broad pools recur across the searches we run.

Sitting CEOs at peer firms. The most common pool — candidates currently running another firm of similar size, complexity and sector position. They have demonstrated they can do the job, they understand what the role involves, and they bring direct sector knowledge. The challenge is that the most credible candidates in this pool are typically not actively seeking moves, and the introduction is the standard way these searches are run. A high-quality search firm will know who in this pool is genuinely open to a conversation at any moment.

Below-CEO executives at larger firms. The natural step-up pool. A COO or division MD at a firm one or two sizes larger, looking to take their first CEO seat. The candidate brings depth from operating in a more demanding environment, with the trade-off that they are taking on the CEO role for the first time and the firm is partly betting on their potential. Strong searches in this pool work hard on reference depth — the question is not just whether the candidate is capable but whether they are ready, and references from chairs, CEOs and boards the candidate has worked with provide the evidence.

Founder-CEOs and serial entrepreneurs. For PE-backed and growth-stage businesses, candidates who have founded and led companies through scale are a distinctive pool. They bring high ownership and entrepreneurial drive, with the trade-off that the operating discipline of a more established firm may be a different muscle from the one they have most recently used. References here focus on how the candidate has handled the transition between stages.

Industry experts and turnaround specialists. For firms in transition — restructuring, post-crisis, sector consolidation — candidates with specific turnaround or transformation experience can be the right answer. The pool is small, the candidates are typically known across the relevant industry, and the conversation often starts before any formal mandate begins.

Internal candidates. The most under-considered pool in many searches. A member of the existing executive team who has been groomed for the role, or a leader from a different part of the group who could step into the CEO seat. Internal candidates have the advantage of knowing the firm, the disadvantage of being known to the firm in their existing role rather than as the future CEO. Strong succession processes test internal candidates against external comparators rather than treating internal succession as a default or as a fallback.

For each pool, the question is not just who is in it but who is in it now. The most credible candidates in any pool typically have multiple options at any given time, and the firms that win them are the ones that move with seriousness and that present the role in a way that respects the candidate’s time and standing.

The search process: what good looks like

A well-run CEO search has six phases that each need to be done deliberately rather than treated as administrative steps.

Phase 1: The brief. Two to three weeks. The board, the chair and the search firm work through the role specification, the candidate pool framing, the compensation envelope, the timeline, and the assessment process. The goal is not just to produce a document but to align everyone involved on what the search is actually for. Searches that compress this phase typically pay for it later.

Phase 2: Market mapping and candidate identification. Four to six weeks. The search firm runs structured market mapping across the relevant pools, identifies named candidates, and begins discreet engagement. The board sees periodic updates on the shape of the candidate pool — which pools are richest, where the gaps are, who is genuinely open to a conversation. Candidates do not yet know they are being considered formally; the engagement is exploratory.

Phase 3: Shortlist development. Three to four weeks. The strongest candidates from the market mapping are engaged formally and proceed through structured assessment. The shortlist that emerges is typically four to six candidates — large enough to give the board genuine choice, small enough that each candidate can be assessed seriously. Shortlists that go above six candidates often signal that the brief was not tight enough.

Phase 4: Board interviews and assessment. Three to four weeks. The shortlist meets the chair, the rest of the board, and (where applicable) major shareholders or PE sponsors. The assessment process should be structured rather than relying on impressions — competency-based interviews, case-style discussion of specific firm challenges, references checked at meaningful depth. The board makes its preferred-candidate decision at the end of this phase, not informally during it.

Phase 5: Selection and offer. Two to four weeks. The preferred candidate is offered the role, the offer is negotiated, and the candidate accepts. Compensation, equity, notice period, start date, board appointment timing — all of this is finalised in this phase. Boards that have not pre-aligned on the compensation envelope often find this phase compressing as the offer evolves through negotiation.

Phase 6: Onboarding and handover. Four to twelve weeks (or longer where the candidate has a long notice period). The candidate works through their existing notice while the firm prepares the onboarding plan, the previous CEO’s handover, the board’s introduction to the new CEO, and the first hundred days. This phase is where succession planning either delivers the value of the work that has gone before or fails to.

The total timeline runs to twenty to thirty weeks. Boards can compress this — but compression typically costs either candidate quality or onboarding rigour, and sometimes both.

Assessment: how to evaluate CEO candidates

CEO assessment is harder than executive assessment more generally because the role is harder to observe directly. Three dimensions matter most.

The substantive track record. What the candidate has actually done in previous roles — the businesses they have run, the strategic decisions they have led, the financial outcomes they have delivered, the teams they have built. References at depth are the evidence here. Not just one-line recommendations but structured reference conversations with previous chairs, board members, key executives and significant shareholders. The strongest assessment processes contact six to ten references across multiple roles, not the two or three references the candidate volunteers.

The judgement quality. How the candidate makes decisions, particularly under uncertainty. Case-style discussion of specific firm challenges — strategic decisions the firm is currently working through, capital allocation questions, executive team gaps, customer or market shifts — surfaces this much better than generic competency interviews. Strong CEO candidates engage with these questions substantively; weaker candidates default to abstract frameworks or to recapping what they have done in previous roles.

The fit with the firm’s specific situation. A CEO who has been excellent at one firm is not automatically the right answer for another. Sector experience matters, but sector adjacency often matters more — a candidate who has run a similar-sized firm in a related sector may be a better fit than a candidate who has run a much larger firm in the exact same sector. Stage fit matters: scale-up CEOs and mature-business CEOs are different animals. Ownership structure fit matters: PE-backed CEOs operate differently from corporate-subsidiary CEOs and from founder-shareholder firms. The assessment process should test these dimensions explicitly rather than assuming they will sort themselves out.

Three things tend to mislead CEO assessment. Personal chemistry with the chair can outweigh evidence on substantive fit if the assessment is not structured to surface the latter. Pattern-matching to the previous CEO — looking for someone like the predecessor — is rarely useful and often counterproductive. Discounting candidates who do not interview brilliantly can mean missing strong candidates whose strengths are operational rather than presentational. Boards that are aware of these traps assess more rigorously.

Compensation: structuring the package

CEO compensation has four components in most UK firms, and each interacts with the others in ways that benefit from being thought through together rather than negotiated piece-by-piece.

Base salary. The fixed annual cash element. Base salaries vary enormously by firm size, sector and ownership structure. For UK SME and mid-market businesses, CEO base salaries typically run from £150,000 to £400,000; for larger private companies and PE-backed portfolio firms in the £20m–£100m revenue range, £400,000 to £750,000 is more typical; for FTSE 250 firms, base salaries run substantially higher and are subject to disclosure and shareholder approval. The base salary anchors the rest of the package and signals where the firm sees the role in the market.

Annual bonus. Performance-related cash, typically a percentage of base salary triggered by financial and non-financial metrics. Bonus structures should be tied to outcomes the CEO can genuinely influence, and should not create perverse incentives that conflict with longer-term value creation. Strong bonus structures combine financial metrics (revenue growth, EBITDA, cash flow) with non-financial metrics (strategic milestones, customer outcomes, talent and culture indicators) in proportions that match the firm’s situation.

Long-term incentives. Equity-linked compensation, typically vesting over three to five years. For listed companies, this is share options, performance share plans or restricted stock. For private companies, it is direct equity, sweet equity (in PE-backed structures), or phantom equity that tracks valuation. The structure of long-term incentives determines whether the CEO’s interests are genuinely aligned with shareholders over the relevant timeframe — and the design carries weight, particularly in PE-backed structures where the equity model is often the dominant economic component for the CEO.

Benefits and other terms. Pension contribution, healthcare, car allowance, life assurance, relocation support where relevant. These elements rarely drive the headline negotiation but they signal the firm’s seriousness and they matter to candidates who are evaluating the offer holistically. Strong offer packages handle these elements at a level that matches the seniority of the role.

Two compensation considerations recur in CEO negotiations. Notice period and termination provisions matter both ways — the firm wants protection against a CEO leaving abruptly, and the candidate wants protection against being terminated without proper transition. Six to twelve months is typical for the CEO seat. Joining payments compensating for unvested awards being left behind at the previous firm are common at senior levels and should be addressed deliberately rather than treated as add-ons; they can change the headline economics of the package materially.

Onboarding: the first hundred days

The first hundred days of a new CEO’s tenure are where the work done before the appointment either delivers value or fails to. Three things typically determine the outcome.

The chair-CEO working relationship. The single most important relationship in the firm, and the one most likely to set the tone for the new CEO’s first year. Strong onboarding includes structured time between the chair and the new CEO before the formal start — covering the chair’s view of the firm, the boundaries between chair and CEO territory, the cadence of their working relationship, and any matters from the previous CEO’s tenure that the new CEO needs to understand. Boards that leave this conversation to define itself in the first hundred days often find friction emerging that compounds rather than resolving.

The executive team relationship. The new CEO inherits the existing executive team and must decide quickly which members are partners in the next phase, which need development, and which need to be replaced. The first hundred days are when this assessment happens — typically through structured one-on-ones, observation of executive committee discussions, and reference work back through the previous CEO’s view of each member. Strong onboarding gives the new CEO the time and information to make this assessment rigorously rather than reactively.

The communication to the firm and to stakeholders. Customers, employees, shareholders, key partners — all of them are watching the new CEO’s first hundred days for signals about what changes and what stays the same. The first formal communications, the first town halls, the first board meeting, the first investor presentation — these set the tone for the year. Strong onboarding plans this communication deliberately rather than treating it as something that will happen naturally.

Boards that invest in the onboarding plan typically see the new CEO settling into the role faster, the executive team aligning more readily, and the strategic priorities the appointment was meant to address moving forward sooner. Boards that treat onboarding as the candidate’s responsibility once they have started often see the opposite.

Common pitfalls in CEO searches

Six patterns recur in CEO searches that go off-track. Each is avoidable with deliberate planning at the start.

Starting too late. The most common failure mode. Boards that have not done succession planning end up running compressed searches under pressure, with predictable consequences for candidate quality and assessment rigour.

An unclear role specification. Specifications that drift through the search — adding criteria, removing criteria, changing emphasis — signal to candidates that the board has not done the work, and the strongest candidates withdraw. The fix is to do the specification work before the search opens.

Letting the chair-CEO relationship define itself. The most consistent source of first-year friction. Strong searches address the relationship explicitly during the offer stage; weaker searches discover the friction in the first ninety days.

Compensation anchored on the firm’s history rather than the market. Boards that treat the previous CEO’s package as the natural reference point often find the strongest candidates declining because the offer is below the relevant market. The fix is to benchmark against the firm’s actual recruitment market, not its own internal history.

Pattern-matching to the previous CEO. Looking for someone like the predecessor — same background, same style, same trajectory — is rarely the right answer because the firm’s situation has changed. The fix is to specify what the firm needs from the next CEO, not what the previous CEO did well.

Treating onboarding as the candidate’s problem. The first hundred days determine whether the appointment succeeds, and they need to be planned by the board and the chair as deliberately as the search itself. Boards that hand the new CEO a calendar and a list of stakeholders rarely get the value of the work that went into the search.

How Exec Capital approaches CEO searches

Exec Capital runs CEO searches as integrated commercial-and-governance work. The substantive search — market mapping, candidate identification, engagement, shortlisting — runs alongside the structural work the board needs to do: the role specification, the chair-CEO relationship, the compensation envelope, the onboarding plan. We work on a retained basis for CEO mandates, and the engagement runs through to the candidate’s first day in role rather than ending at offer acceptance.

Our CEO practice covers UK owner-managed and PE-backed businesses, scale-ups, mid-market firms, and corporate subsidiaries. Where the appointment is into an FCA-regulated firm, we layer the regulatory dimension over the commercial brief — see our SMF1 CEO hiring guide for how we approach regulated CEO appointments. Where the firm operates in a sector with specific regulatory or governance frameworks beyond SMCR — healthcare, education, energy, public sector adjacent — we build that dimension into the search from the brief.

Every CEO mandate is led personally by Adrian Lawrence FCA. The role is too consequential — and the candidate-firm fit too important — to be handed to a junior consultant or generalist. For boards beginning CEO succession or refreshing how they have approached previous searches, we offer a structured initial conversation that walks through the role specification, the candidate pool framing and the realistic timeline before any formal mandate begins. There is no commitment from this conversation; boards often use it to check their thinking before deciding whether to commission a search.
