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

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

The Chief Operating Officer is the executive most directly accountable for whether the firm actually delivers on what it promises — operationally, commercially, and at scale. The role has shifted substantially over the past decade as firms have grown more complex, customer expectations have tightened, and the operational dimensions of competitive advantage have become more visible. The modern COO at a UK mid-market business is doing a fundamentally different job from the COO at a £200m PE-backed group, and both are different again from the COO at an FCA-regulated firm holding SMF24 accountability. Hiring a COO is consequential because the appointment shapes the firm’s operational reliability for several years, defines the executive team’s capacity to scale, and is the single most common appointment that fails when boards under-specify the role at the front end.

This guide is written for chairs, CEOs, founders and shareholders working through COO succession at UK firms. It sets out what a COO appointment actually involves: when the firm needs a COO rather than a Head of Operations or Operations Director, what the role covers, what the candidate pool looks like at different company stages, how the search process should run, how to think about compensation and incentives, and what the first hundred days look like. For our COO recruitment service across the engagement models — permanent, interim, fractional — see COO recruitment. For COO appointments to FCA-regulated firms holding SMF24 (Chief Operations Function), see our SMF24 hiring guide.

The COO role and its variations

The COO seat looks different in different firms. The four most common patterns boards encounter are worth distinguishing because they attract distinct candidate pools and warrant different role specifications.

The COO as operational delivery leader. The most established version of the role. The COO owns the firm’s operational functions — operations, supply chain, customer operations, support, sometimes technology and HR — and is accountable for delivery, performance, scaling and operational excellence. The CEO sets strategy and runs commercial; the COO runs the engine room. This pattern is most common in established mid-market and larger businesses, particularly in services, manufacturing, logistics and complex B2B firms.

The COO as second-in-command. The COO operates as the CEO’s deputy across the breadth of executive responsibility — running day-to-day execution while the CEO focuses on external relationships, strategic direction, fundraising or M&A. This pattern is common in founder-led businesses where the founder-CEO needs operational support, in scale-ups where the CEO is heavily external, and in PE-backed structures during transformation periods. Strong “second-in-command” COOs typically have substantive prior CEO or general management experience, and the role often functions as a CEO-in-waiting position.

The COO as transformation leader. The COO is brought in specifically to lead operational transformation — system replacement, process redesign, post-acquisition integration, scale-up operational maturation, regulatory remediation. The role has a defined transformation scope alongside ongoing operational accountability, and the candidate is typically chosen for a specific track record of delivering similar transformations elsewhere. This pattern is common in PE-backed portfolio companies, post-merger businesses, and firms responding to material operational failures.

The COO as functional executive. The COO runs a specific bundle of functions at executive level — typically operations plus customer service, or operations plus technology, or operations plus HR — without the breadth of either the operational-delivery or second-in-command patterns. This is most common in smaller mid-market businesses where the executive team is narrower, and in firms where the CEO retains much of the operational accountability personally.

Boards approaching their first COO appointment, or refreshing the role after several years, benefit from clarifying which pattern the firm needs before the search begins. Each pattern has different implications for candidate pool, compensation structure, executive team positioning and onboarding.

When does a firm need a COO?

Not every firm needs a COO. Many UK businesses run effective operations through a combination of an Operations Director, functional heads, and a CEO who plays the operational integration role at executive level. The decision to upgrade to a dedicated COO at executive level should be deliberate. Five triggers typically signal the move is warranted.

Operational scale and complexity. Multi-site operations, multi-jurisdiction footprint, complex supply chains, large operational teams, growing customer base with material service expectations. At this scale the operational function needs strategic leadership for the same reasons the finance function does — the strategic decisions are too consequential for departmental management.

CEO capacity and focus. The CEO is the operational integrator by default in many firms. When the CEO’s external commitments — investor relations, M&A, fundraising, customer-facing strategy, regulatory engagement — grow beyond the time available alongside operational accountability, a COO typically becomes necessary. Boards often see this trigger only after the CEO has been over-stretched for a year, by which point operational performance has typically already deteriorated.

Strategic transition. Acquisition activity at scale, international expansion, business model evolution, technology platform replacement, post-merger integration. These transitions require operational leadership at executive level rather than departmental management.

Investor or capital structure changes. PE investment, growth capital raise, IPO preparation. PE sponsors in particular increasingly expect to see a COO in the management team as part of the operational-execution dimension of the investment thesis — partly because PE governance puts substantial weight on operational performance metrics and partly because the COO seat creates the executive accountability the sponsor needs visibility into.

Regulatory or governance demands. FCA-regulated firms with SMF24 (Chief Operations Function) responsibility have a baseline regulatory expectation of senior operational leadership. Operational resilience accountability under the FCA’s Operational Resilience policy similarly demands executive-level operational ownership.

Where none of these triggers applies, an Operations Director reporting to the CEO may be the right answer. Firms that appoint a COO without the underlying triggers often find the role under-defined and the appointment failing to deliver the value that justified it.

What a COO actually does

The substantive work of the COO role splits into five areas, with the proportions varying by which COO pattern the firm has appointed.

Operational delivery and performance. The foundational responsibility. The COO is accountable for whether the firm’s operations actually work — delivery against operational metrics, customer service performance, supply chain reliability, process efficiency, operational quality. This is the part of the role that least tolerates failure. A COO who delivers strategic vision but cannot maintain operational performance is in a weaker position than one who can.

Operational scaling and transformation. Building the operational capability the firm needs as it grows or evolves — system selection and implementation, process design and redesign, organisation structure, capability building, operational technology choices. Strong COOs combine continuity (keeping current operations working) with change (building what the firm needs next); weaker COOs typically over-emphasise one at the expense of the other.

Cross-functional integration. The COO is often the executive most directly accountable for whether the firm’s functions work together — operations and sales, operations and finance, operations and technology, operations and HR. This integration dimension is one of the most consistent distinctions between COO-level capability and Operations Director capability. Strong COOs are partners across the executive team; weaker COOs run operational silos.

Risk and resilience. Operational risk, business continuity, supply chain risk, third-party risk, operational resilience. This dimension has grown substantially in importance over the past five years, particularly post-pandemic and following increased FCA and PRA emphasis on operational resilience for regulated firms. COOs in regulated contexts may hold SMF24 personally; COOs in non-regulated firms still typically own operational risk at executive level.

Executive contribution. The COO sits on the executive committee and typically the board, contributing to decisions beyond the operational remit — strategy, M&A diligence, organisational design, talent and culture, technology investment. Strong COOs are partners to the CEO on these questions; weaker COOs are confined to the operational silo and are typically replaced sooner.

The COO candidate pool

The UK COO candidate pool is reasonable in size but has tightened at the senior end as demand has grown across mid-market and PE-backed businesses. Five pools recur across the searches we run.

Sitting COOs at peer firms. The most common pool — candidates currently holding COO at another firm of similar size, sector and complexity. They have demonstrated they can do the job, they understand what the role involves, and they bring direct sector experience. The challenge is that the most credible candidates in this pool have multiple options at any given time. Discreet introduction is the standard search method.

Operations Directors at larger firms stepping up. The natural step-up pool. An Operations Director or VP Operations at a substantially bigger business who is ready for the C-suite seat at a smaller firm. The candidate brings depth from operating in a more demanding environment, with the trade-off that they are taking the executive-leadership seat for the first time. Strong searches in this pool focus on whether the candidate has demonstrated the cross-functional integration and executive contribution alongside operational delivery.

Sector-specialist COOs from related industries. Where the firm operates in a sector with specific operational dynamics — financial services, healthcare, logistics, manufacturing, regulated industries — candidates who have run senior operational functions in similar contexts bring relevant breadth. Sector transferability matters and is real, but specific operational disciplines and stakeholder relationships often warrant sector experience.

Big Four and consulting firm transitions. Senior partners and directors from operations consulting firms transitioning into in-house COO roles. The pool brings strong methodology depth and broad sector exposure, with the requirement that the candidate has made the substantive transition from advisory to operating leadership.

Functional executives stepping across. Candidates whose recent senior roles have been in CFO, Chief Customer Officer or Chief Technology Officer roles where operations were a substantial part of their accountability, who are now ready to take on the breadth of the COO seat. These cross-functional candidates can be credible particularly where the firm’s operational function is integrated heavily with finance, technology or customer experience.

Engagement models — permanent, interim, fractional

We place COO appointments across all three engagement models, and each fits different situations.

Permanent COO appointments are the most common. The role is structurally part of the executive team and continuity matters for operational performance. Permanent searches run on the timeline and process described below, with retained engagement throughout.

Interim COO appointments are common during transitions — operational transformations, technology platform replacements, post-acquisition integrations, regulatory remediation, or to bridge a gap between a departing COO and a permanent successor. Interim engagements are full-time during the period but with a clear end date. The candidate is typically chosen for a specific track record of similar interim assignments rather than for long-term cultural fit, and the engagement runs from a few months to two years depending on the transformation scope.

Fractional COO appointments work in smaller mid-market firms where the operational dimension warrants executive-level leadership but the firm size does not justify a full-time appointment. Our fractional COO service is currently the strongest performer in our engagement-model network, reflecting the genuine UK market demand for fractional senior operational leadership at growth-stage and PE-backed scale-up businesses. Fractional COOs typically work two or three days per week across one or two firms, providing executive-level operational leadership without the full-time cost.

Across all three models, the substantive work is the same. The differences are time commitment, engagement structure and continuity expectations.

The search process

A well-run COO search has six phases. Total timeline runs to fourteen to twenty weeks for non-regulated COO appointments. For FCA-regulated firms requiring SMF24 approval, add four to twelve weeks for the FCA Form A approval window — see our SMF24 hiring guide for the regulated process detail.

The brief. Two to three weeks. The board, the CEO and the search firm align on which COO pattern the firm needs (operational delivery, second-in-command, transformation, functional), the role specification, the candidate pool framing, the compensation envelope and the timeline. COO specifications particularly benefit from clarifying which pattern matters most rather than presenting a generic COO role.

Market mapping and candidate identification. Three to five weeks. Structured market mapping across the relevant pools, named candidate identification, and discreet engagement.

Shortlist development. Two to three weeks. Strongest candidates from market mapping engaged formally and proceed through structured assessment. COO shortlists typically run to four to six candidates.

Interviews and assessment. Three to four weeks. The shortlist meets the CEO, the rest of the executive committee, the chair, and (where applicable) major shareholders or PE sponsors. COO assessment combines operational depth with executive-leadership capability and the integration dimension.

Selection and offer. Two to three weeks. Preferred candidate offered the role, offer negotiated, candidate accepts. COO compensation negotiations frequently involve substantive work on the variable compensation structure and equity component, particularly in PE-backed structures.

Onboarding and handover. Three to twelve weeks. The new COO works through their existing notice while the firm prepares the executive committee onboarding, the operational team’s introduction, and the first hundred days plan.

Assessment: how to evaluate COO candidates

COO assessment combines operational depth with executive-leadership capability. Three dimensions warrant particular attention.

Operational track record at scale. Strong COO candidates can articulate their operational contribution in defensible numbers — operational performance improvement, cost reduction, capacity scaling, customer service metrics, transformation outcomes. Case-style discussion of specific operational challenges the firm faces — process redesign, capacity scaling, technology platform replacement, organisational design — surfaces this much better than generic competency interviews. Candidates who default to abstract frameworks rather than engaging with specifics often turn out to have less operational substance than they present.

Cross-functional integration capability. The dimension that separates strong COOs from senior Operations Directors who have been promoted prematurely. Strong COOs operate across operations, finance, sales, technology, HR — integrating outcomes from across the firm rather than running a siloed operational function. References from CFOs, CMOs, CTOs and other C-suite executives the candidate has worked alongside provide the most reliable evidence of this dimension.

Executive contribution and influence. The COO needs to operate at executive level, partnering with the CEO and contributing to strategic decisions beyond the operational remit. References from previous CEOs and chairs the candidate has worked with provide the evidence here. COOs who have been operationally strong but who have struggled to influence at executive level often do not transition into the second-in-command pattern effectively.

One specific assessment trap recurs in COO searches: confusing operational management with COO leadership. Candidates who have run large operational functions effectively are not automatically candidates who can lead at executive level across the integration, transformation and strategic dimensions the COO seat requires. The assessment should test the executive dimension explicitly.

Compensation

UK COO compensation has the four standard components — base salary, annual bonus, long-term incentives, benefits — with the levels and structure varying significantly by firm size, sector and ownership.

SME and mid-market COOs (firms in the £15-50m revenue range) typically see base salaries from £130,000 to £220,000, annual bonus opportunity of 20-40% of base, and long-term incentive structures that vary by ownership. PE-backed firms typically include sweet equity participation; founder-led firms may grant equity to bring senior operational leaders aboard.

Larger private and PE-backed COOs (firms in the £50-300m revenue range) typically see base salaries from £200,000 to £400,000, annual bonus opportunity of 30-50% of base, and LTI structures dominated by sweet equity in PE-backed firms or significant equity grants in larger private firms. PE-backed COO appointments often involve material equity structures that can change the headline economics significantly.

Listed and FTSE 250 COOs see substantially higher compensation, structured around shareholder-approved remuneration policies. Base salaries run from £400,000 upward; LTI structures designed for multi-year value creation aligned to operational and commercial outcomes.

Sector premiums and specifics. Financial services COOs typically command higher compensation than equivalent COOs in other sectors, reflecting the regulatory dimension and SMF24 personal accountability where applicable. Industrial and manufacturing COOs typically see somewhat lower bases reflecting sector norms but with strong variable components tied to operational performance metrics. Technology and SaaS COOs often have heavier equity components reflecting venture and growth-equity structures.

Common COO search pitfalls

Six patterns recur in COO searches that go off-track.

Briefing an Operations Director rather than a COO. The most common failure mode. Specifications that emphasise operational delivery and team management without the strategic, integration and executive-leadership dimensions attract candidates whose seniority does not match the firm’s needs.

Confusing the COO patterns. Specifications that mix operational-delivery and second-in-command dimensions without making the priority explicit attract a confused candidate pool. The fix is to clarify the pattern before the search opens.

Underspecifying the CEO-COO relationship. The most important working relationship for the new COO. Specifications that do not address the relationship miss a dimension that strong candidates probe carefully. Boards that leave the chair-CEO-COO triangle to define itself often find friction emerging in the first ninety days.

Compensation anchored on internal precedent. COO compensation has shifted upward as the senior operational leadership market has tightened. Boards benchmarking against historical internal precedent or against Operations Director compensation often produce offers that strong candidates decline.

Pattern-matching to the previous COO. Looking for a COO who looks like the predecessor — same background, same sector, same career path — is rarely the right answer because the firm’s situation has typically shifted.

Underestimating the FCA approval timeline for regulated firms. COO appointments to FCA-regulated firms holding SMF24 require regulatory approval. Boards that have not factored four to twelve weeks of FCA approval into their timeline often face regulatory gaps. See our SMF24 hiring guide for the regulated firm timeline detail.

The first hundred days

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

The CEO-COO working relationship. The most important working relationship for the new COO. Strong onboarding includes structured time between the CEO and the new COO before the formal start — covering the CEO’s view of the operational trajectory, the boundaries between CEO and COO territory, the cadence of their working relationship, and any matters from the previous COO’s tenure that the new COO needs to understand.

The operational team review. The new COO inherits the existing operational organisation and must decide quickly which leaders are partners in the next phase, which need development, and which need to be replaced. The first hundred days are when this assessment happens — through structured one-on-ones, observation of operational reviews, and reference work back through the previous COO’s view of each member where possible.

The first operational review. Most new COOs face the question of where the firm’s actual operational performance sits versus where the previous COO had been reporting. Strong onboarding gives the COO the time and information to do this review rigorously rather than reactively — including operational performance metrics, customer service health, supply chain or third-party risk, technology platform stability, and the realistic operational forecast for the next twelve months.

How Exec Capital approaches COO mandates

Exec Capital runs COO searches as integrated operational-and-executive-leadership work. The substantive operational dimension — operational track record, transformation capability, cross-functional integration, risk and resilience — receives the same rigour we bring to any senior C-suite search. The executive leadership dimension is built in alongside it. We work on a retained basis for COO mandates, and the engagement runs through to the candidate’s first day in role.

Our COO practice covers UK SME, mid-market, PE-backed, scale-up and corporate businesses across financial services, professional services, technology, industrial, manufacturing, healthcare and consumer sectors. We run permanent, interim and fractional COO mandates — see our COO recruitment, interim COO and fractional COO service pages for the engagement-model detail. Where the appointment is into an FCA-regulated firm and the COO will hold SMF24, we layer the regulatory dimension over the commercial brief.

For boards beginning COO succession, considering whether the firm needs a COO at all rather than a strong Operations Director, or working through the COO-pattern question, 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. Every COO mandate is led personally by Adrian Lawrence FCA — there are no junior account managers running these searches at Exec Capital.
