Part-Time COO

UK Part-Time Chief Operating Officer Search — Ongoing 2-3 Day Per Week COO Engagements at Scaling Firms, SMEs and PE-Backed Companies

Exec Capital provides retained Part-Time Chief Operating Officer search across the UK SME, scaling firm, and private equity backed firm community. The Part-Time COO is a specific senior operations function delivery model — typically structured as an ongoing single-employer engagement at 2-3 days per week, with the senior Operations leader holding the firm’s named COO role on a continuing basis but at materially less than full-time hours. Part-Time COO appointments are common at UK firms where senior operations leadership capability is essential — typically post-Series A scaling firms, owner-managed UK SMEs scaling operational complexity, PE-backed portfolio companies in scaling phases, and pre-IPO firms preparing the operating model for the listed-firm transition — but where the firm’s headcount, operational complexity, or budget does not yet warrant full-time COO engagement. The model is structurally distinct from the Fractional COO model (multi-client engagement on a day-rate basis serving 2-5 client firms), the Interim COO model (full-time but time-bound, typically 3-9 month gap-fill or transition assignments), the broader full-time UK COO recruitment market, and the senior PE firm-level COO role covered separately on our PE Chief Operating Officer recruitment page.

UK Part-Time COO appointments have grown materially through 2018-2024 alongside the increasing operational complexity of UK scaling firms, the maturation of UK PE-backed mid-market platforms requiring senior operational leadership through specific hold-period phases, and the broader recognition across UK SMEs that senior operations leadership is essential for scaling operational performance. Part-Time COO appointments give scaling firms access to senior COO leadership at C-Suite tier capability without the full-time budget commitment, with senior COO candidates frequently bringing strategic and operational capability built at FTSE 250 or major firm level to scaling firms at materially smaller scale.

The Part-Time COO Model — How It Differs From Fractional, Interim and Full-Time Arrangements

Understanding the structural distinctions between Part-Time COO, Fractional COO, Interim COO, and full-time COO models is essential at the brief stage because each model serves materially different firm scenarios and draws from different senior candidate pools.

Part-Time COO model — the COO is the firm’s named COO operating on an ongoing basis at 2-3 days per week (sometimes 3-4 days per week at slightly larger firms). The Part-Time COO holds the senior Operations role at the firm, attends senior leadership team meetings, owns the firm’s operational strategy and senior Operations decisions, and accepts personal accountability for the role in the same way as a full-time COO. The arrangement is structured as ongoing employment or as a continuing services agreement, with longer commitment expectations than interim engagements. Compensation is typically structured as pro-rated COO salary (calibrated against the equivalent full-time COO compensation at the firm’s scale) plus equity participation where applicable.

Fractional COO model — the Fractional COO operates on a day-rate basis serving 2-5 client firms simultaneously, with no single client firm holding the candidate’s senior COO role exclusively. The Fractional COO is the firm’s principal external operations senior support but is not the firm’s named COO. The Fractional COO model is the most common flexible operations leadership arrangement at UK SMEs and scaling firms. Cross-references with our Fractional COO recruitment page support firms specifically seeking the Fractional model.

Interim COO model — the Interim COO operates full-time on a defined 3-9 month assignment to fill a gap (departing COO succession, parental leave cover) or support a specific transition (post-acquisition operations integration, organisation restructuring, operational turnaround). The Interim COO holds the firm’s COO role for the assignment duration but operates with explicit time-bound engagement. Cross-references with our Interim COO recruitment page support firms specifically seeking the Interim model.

Full-time COO model — the standard COO appointment with the candidate operating full-time as the firm’s senior operations leader, typically structured as full-time employment with the standard senior compensation framework appropriate to the firm’s scale. Cross-references with our COO recruitment page support firms seeking full-time COO appointments.

The model selection matters because role expectations, candidate fit, and offer construction differ across the four models. Search engagement design needs to recognise these candidate-pool distinctions explicitly at the brief stage.

The COO Role and Distinction From Operations Director Positioning

The COO designation typically signals senior strategic operations leadership distinct from the Director-tier Operations Director seniority. Understanding the seniority distinction matters at the brief stage because senior COO and senior Operations Director candidates draw from materially different career backgrounds.

Chief Operating Officer (COO) positioning — the COO designation typically signals senior C-Suite tier operations leadership focused on strategic dimensions of the operations function: operational strategy and scaling operations design, organisation design and senior team architecture across operating functions, customer operations and customer success leadership, technology operations and IT infrastructure strategy, supply chain or service delivery senior leadership, and the senior commercial dimensions of operations function leadership. The COO typically operates as a senior C-Suite tier role with reporting line direct to the CEO and material accountability to the Board.

Operations Director positioning — the traditional Operations Director positioning operates at Director-tier seniority with focus on operational programme execution, day-to-day operations management, operational team leadership, and the operational dimensions of operations delivery. Operations Director appointments at major UK firms typically report into a COO at firms with senior operations function leadership in place. Cross-references with our wider Operations Director recruitment practice support firms specifically seeking Director-tier operations leadership rather than C-Suite tier COO appointments.

When UK Firms Use Part-Time COOs — Five Common Scenarios

UK Part-Time COO appointments typically arise in five common firm scenarios.

Scaling firm post-Series A through Series C

Scaling UK firms post-Series A through Series C funding (typically 50-300 employees, £5m-£40m revenue) frequently use Part-Time COO appointments as operational complexity grows beyond Head of Operations or Operations Director scope. Scaling firms at this stage typically need senior strategic operations leadership for scaling team architecture, customer operations design, technology operations infrastructure, organisation design through rapid growth phases, and the senior dimensions of operations function leadership during scaling.

Owner-managed SME at scale needing senior operations capability

UK SMEs at the owner-managed £5m-£50m revenue scale frequently use Part-Time COO appointments as the firm’s permanent senior Operations arrangement — particularly at firms where the founder-CEO recognises the importance of senior operations leadership but the firm’s headcount and operational complexity do not yet warrant full-time COO engagement. Part-Time COO appointments at owner-managed SMEs can extend across multi-year periods as the firm’s preferred ongoing arrangement.

PE-backed portfolio company in scaling phase

Private equity backed portfolio companies at the lower mid-market scale (typically £10m-£75m revenue, £2m-£15m EBITDA) frequently use Part-Time COO appointments during specific phases of the PE hold period — typically post-acquisition operational integration, scaling phase senior operations leadership, pre-exit operational professionalisation, and the senior Operations dimensions specific to PE-backed firm operations. Cross-references with our wider private equity recruitment practice support senior PE-backed firm appointments.

Pre-IPO firm preparing the operating model for listed-firm transition

UK firms preparing for IPO frequently use Part-Time COO appointments in the pre-IPO preparation phase to mature the senior Operations function for the listed-firm transition. Pre-IPO Part-Time COO scope typically includes operational reporting framework preparation for the listed-firm requirements, senior operations team development aligned with the IPO timeline, organisation design for the listed-firm operating model, and the senior Operations dimensions specific to the IPO transaction process.

Specialist sector firms at niche scale

Specialist UK firms in niche sectors — life sciences firms in early commercial deployment, specialist financial services firms at boutique scale, professional services firms at partnership scale, specialist technology firms at sub-£25m revenue — frequently use Part-Time COO appointments as the firm’s preferred ongoing arrangement reflecting the firm’s specific scale and structure.

The Part-Time COO Senior Candidate Pool

UK Part-Time COO senior candidates draw from specific senior career communities.

Senior COOs transitioning to portfolio-of-engagements arrangements — the principal Part-Time COO candidate pool. Senior COOs typically transition to Part-Time COO engagements after 15-25+ years of full-time senior operations function history at scale firms, frequently from FTSE 250, FTSE Small Cap, PE-backed UK firms, or major private firms. These candidates typically operate with one or two Part-Time COO appointments alongside selected non-executive director or advisory roles.

Senior COOs returning from international assignment — UK-trained senior operations leaders returning from major international assignments who choose to build Part-Time COO portfolios on UK return rather than returning to full-time senior employment. Repatriation candidates frequently bring extensive international business knowledge and cross-cultural senior leadership capability.

Senior consulting and advisory candidates with COO experience — senior consultants from major management consulting firms (McKinsey, Bain, BCG, Deloitte Consulting) with prior senior COO or operations function experience who transition to Part-Time COO appointments at scaling firms or PE-backed firms. Consulting background candidates typically bring strong analytical capability, organisation design experience, and senior advisory background that supports complex Part-Time COO scenarios.

Senior Operations Directors progressing to senior portfolio COO roles — senior UK Operations Directors who have built senior careers at FTSE 250 firms or major private firms and progress to Part-Time COO appointments as the senior career step beyond full-time Operations Director seniority.

Compensation Calibration at Part-Time COO Level

UK Part-Time COO compensation typically operates on a pro-rated basis calibrated against the equivalent full-time COO compensation at the firm’s scale.

Pro-rated base salary — at scaling UK firms (£5m-£25m revenue), full-time COO equivalent base salary typically operates in the £125,000-£200,000 range, giving a 2-day per week Part-Time COO base salary in the £50,000-£80,000 range. At PE-backed lower mid-market firms (£25m-£75m revenue), full-time COO equivalent base salary typically operates in the £175,000-£300,000 range, giving a 2-day per week Part-Time COO base salary in the £70,000-£120,000 range. At larger UK firms, the full-time-equivalent base salary scales with the firm’s size and complexity.

Day-rate structure as alternative — typical UK Part-Time COO day rates operate in the £1,000-£1,800 per day range at scaling firms and £1,500-£2,500+ per day at PE-backed and larger UK firms.

Equity participation — Part-Time COO engagements at scaling firms, PE-backed firms, and pre-IPO firms typically include meaningful equity participation alongside cash compensation. Equity participation frequently dominates total economic value at successful firm exits or IPO transactions.

Bonus arrangements — Part-Time COO bonus arrangements typically operate on a pro-rated basis aligned with the firm’s bonus framework. Performance criteria typically reflect the firm’s commercial KPIs alongside Operations-specific deliverables (operational efficiency metrics, customer operations performance, technology infrastructure milestones, organisation design delivery).

Total economic positioning — strong Part-Time COO senior candidates building portfolios of 1-2 senior Part-Time engagements alongside non-executive director appointments frequently achieve total economic positioning materially comparable to full-time senior COO compensation while operating with the flexibility advantages of portfolio-of-engagements arrangements. Senior Part-Time COOs at the most senior end of the market commonly operate with combined annual economic value exceeding £150,000-£300,000 across two Part-Time COO appointments plus 2-3 non-executive director appointments.

How Exec Capital Approaches Part-Time COO Search

UK Part-Time COO search at Exec Capital follows a retained methodology calibrated to the specific dynamics of senior part-time operations function leadership recruitment.

Brief development — initial work focuses on defining the firm’s specific Part-Time COO requirement (firm scale, sector context, scaling phase or PE-backed context), the specific scenario the appointment supports, the days-per-week expectation, the operations function scope under the COO (whether the role extends to customer operations, technology operations, supply chain, or focuses on broader strategic Operations leadership), the realistic compensation envelope including equity arrangements, and the candidate-fit dimensions specific to the firm’s senior team and Board.

Senior candidate identification — UK Part-Time COO candidate identification operates across senior COOs operating with established Part-Time COO portfolios, senior COOs transitioning to portfolio-of-engagements arrangements, senior consulting candidates with COO experience, senior COOs returning from international assignment to portfolio arrangements, and senior Operations Directors progressing to senior Part-Time COO seniority.

Engagement structure assessment — explicit assessment of the candidate’s preferred engagement structure (employment vs services agreement, days-per-week preference, board director appointment willingness, location and travel arrangement, restrictive covenant compatibility with the candidate’s other portfolio engagements) ensures fit between the firm’s structural preferences and the candidate’s portfolio arrangement.

Interview process — typically 3-5 rounds for Part-Time COO appointments, generally compressed compared to full-time COO process given the experienced senior candidate pool. Interview process typically includes CEO-led senior interview, peer C-Suite leader engagement (CFO, CRO, CTO, CPO), Board chair engagement (where applicable), and (at PE-backed firms) PE firm portfolio operations team engagement at advanced shortlist stage.

Offer construction and onboarding — Part-Time COO offer construction typically involves negotiation around days-per-week structure, base salary or day-rate calibration, equity participation arrangements, board director appointment, restrictive covenant compatibility with the candidate’s other portfolio engagements, and the practical onboarding logistics of senior part-time arrangement.
