Perplexity: both observations

For this mandate, I would shortlist a hybrid panel : one specialist payroll executive-search firm, one PE/HR-leadership search firm, and one broad international search firm. The role is unusual because it combines deep UK payroll operations with cross-border integration, provider management, controls and PE value-creation experience.

Recommended shortlist

| Firm | Why shortlist | Best use |

| --- | --- | --- |

| Portfolio Payroll / The Portfolio Group | The strongest pure payroll-specialist option: it recruits Payroll Directors, Heads of Payroll, Global Payroll Managers and Payroll Transformation Leads, and offers dedicated executive search for senior payroll roles. theportfoliogroup +1 | Lead specialist search for candidates who have actually run multi-entity payroll, shared-service transitions and payroll-provider rationalisation. |

| Oakleaf Partnership | Its dedicated payroll practice covers permanent and interim roles up to Global Payroll Directors and Global Payroll Implementation Managers, with UK and international sourcing capability. oakleafpartnership +1 | A strong second specialist firm, particularly if you need interim integration leadership alongside the permanent hire. |

| Robert Walters Executive Search | A credible broad executive-search option with UK reach; its executive-search model uses market mapping, confidential outreach and assessment to reach less visible senior candidates. [Trusted domain robertwalters.co](https://robertwalters.co.uk/our-services/executive-search.html) | Useful where the successful candidate may come from finance transformation, shared services, HR operations or PE-backed group functions rather than a conventional payroll title. |

| Berwick Partners (Odgers Berndtson) | A leading UK HR senior-leadership and executive-search consultancy, with access to a global HR talent pool through the Odgers group. [Trusted domain berwickpartners.co](https://berwickpartners.co.uk/hr/) | Best if you want a retained, board-level search and expect the role to sit close to the Group CFO/CHRO agenda. |

| Marble Hill Partners | Explicitly partners with UK PE investors, portfolio companies and CEOs to hire senior leaders for growth, transformation, value creation and exit; its remit includes Chief People Officer and HR Director searches. [marblehillpartners](https://marblehillpartners.com/) | Strong choice if the mandate is explicitly PE-led and requires someone credible with investors and an integration/value-creation plan. |

| Bronzegate | A London-based specialist executive-search and interim firm focused on PE-backed portfolio companies, particularly finance, technology and transformation leadership. [linkedin](https://linkedin.com/company/bronzegate-search) | Worth including for PE-network access and transformation-oriented candidates, though payroll depth should be tested carefully. |

Suggested panel structure

• Retained search: Berwick Partners, Marble Hill Partners or Robert Walters Executive Search.

• Specialist payroll search: Portfolio Payroll and Oakleaf Partnership.

• PE/transformation overlay: Marble Hill Partners or Bronzegate.

• Interim cover: Oakleaf Partnership and Portfolio Payroll, both of which can source interim payroll leadership while the permanent Group Payroll Director is recruited. oakleafpartnership +1

What to test in candidates

For your specific situation, prioritise evidence of:

• Running payroll across multiple acquired UK and European entities, including TUPE, entity onboarding, harmonisation and de-duplication.

• Managing or replacing payroll bureaux, EOR providers and in-house teams; including SLA, pricing, data-migration and exit management.

• Designing a target operating model: shared services versus local payroll, centralised controls, calendar governance, and payroll-system strategy.

• UK compliance depth—RTI, auto-enrolment, statutory payments, P11D/benefits, HMRC audits—and practical awareness of EU country payroll differences.

• Controls and assurance: SOX-style controls where relevant, reconciliation, segregation of duties, year-end controls, and audit remediation.

• PE experience: integration at pace, cost synergies, reporting to a board or investment committee, and working alongside CFO/CHRO transformation leads.

Briefing approach

Run the specialist firms on a contingent or exclusive specialist brief , but reserve the broader retained search for a tightly defined “Group Payroll & Payroll Transformation Director” mandate. Ask each firm for anonymised examples of multi-country payroll integration, provider consolidation, and PE-backed payroll transformation—not simply director-level payroll placements.

The clearest first calls would be Portfolio Payroll, Oakleaf Partnership, Marble Hill Partners and Berwick Partners ; add Robert Walters if you want a wider transformation and shared-services talent pool. robertwalters.co +4

For this mandate, shortlist a small mix of one specialist payroll recruiter plus two or three PE-focused finance/transformation search firms . The role is unusual: it needs genuine multi-country payroll operating credibility, provider-management experience, and the political/controls skills to integrate acquired businesses—so avoid treating it as a standard senior finance hire.

Recommended shortlist

| Firm | Why shortlist | Best use |

| --- | --- | --- |

| Portfolio Payroll / The Portfolio Group | The UK’s largest specialist payroll recruiter, recruiting from payroll administrator through to Payroll Director, including international payroll, pensions, reward and payroll-systems implementation specialists. It also has dedicated executive and interim/contract teams. theportfoliogroup +2 | Essential first call for market mapping and access to payroll-specific talent; ask for its executive-search team, not general payroll consultants. |

| Bronzegate | A London-based specialist executive search and interim firm focused specifically on finance, technology and transformation leadership for PE-backed portfolio companies. [linkedin](https://www.linkedin.com/company/bronzegate-search) | Strong fit for a PE value-creation and post-acquisition integration lens. |

| Marble Hill Partners | Works with UK PE investors and CEOs on C-suite and C-1 searches, and explicitly identifies CFOs, integration directors, transformation directors and group people directors with post-acquisition integration experience. [marblehillpartners](https://marblehillpartners.com/) | Particularly relevant if the mandate includes operating-model design, provider consolidation and cross-border integration. |

| Broster Buchanan | Partners with PE firms and portfolio companies on leadership and specialist appointments across finance, IT and business transformation, including CFOs, transformation directors and programme leads; offers permanent and interim capability. [brosterbuchanan](https://brosterbuchanan.com/market/private-equity/) | Good option if you want a broader transformation/search partner and possible interim cover during the integration. |

| Robert Walters | A major UK accounting-and-finance recruiter with senior finance search capability, including CFO/Finance Director appointments for public and PE-backed companies. [robertwalters.co](https://www.robertwalters.co.uk/expertise/accounting-and-finance.html) | Useful for scale, speed and access to senior finance leaders who can stretch into payroll ownership—but probe payroll depth carefully. |

| Robert Half | Recruits permanent and interim finance leaders for PE, VC and founder-led businesses, spanning CFO through financial controller and transformation-oriented roles. [roberthalf](https://www.roberthalf.com/gb/en/finance-accounting-recruitment/finance-leadership) | Strong for interim payroll/finance leadership or a dual-track permanent-plus-interim search. |

How to split the mandate

• Run Portfolio Payroll as the payroll-specialist track. It is the clearest choice for candidates who have actually led UK and European payroll operations, outsourcer transitions, payroll-platform implementations, controls and compliance. theportfoliogroup +2

• Run Bronzegate or Marble Hill as the PE/integration track. Their positioning is closer to your situation: PE-backed companies, value creation, transformation and post-acquisition leadership. linkedin +1

• Consider Robert Half or Broster Buchanan for interim capacity. A fractional or interim Group Payroll Director can stabilise providers, map country-by-country obligations and design the target operating model before a permanent appointment lands. roberthalf +1

What to test candidates on

• Multi-country payroll ownership: UK plus EU payroll jurisdictions, local providers, EOR/AGG arrangements, currency, statutory reporting and cross-border data flows.

• Provider consolidation: experience moving from multiple acquired-company vendors to a managed model—without disrupting pay dates, pensions, benefits or works-council-sensitive changes.

• Controls and assurance: payroll calendars, segregation of duties, SOX-style or PE reporting controls, HMRC/P11D, pension auto-enrolment, audit readiness and error remediation.

• Integration leadership: TUPE/employee communications, legacy-team rationalisation, system migrations and working with CFO, HR, IT and deal teams.

• PE operating style: comfort with rapid value-creation plans, board reporting, KPI design and a lean central team.

Practical approach

Invite three firms to pitch : Portfolio Payroll, Bronzegate and Marble Hill Partners. Ask each for five anonymised, comparable placements—Group Payroll Director, Head of International Payroll, Payroll Transformation Director, or CFO-1 payroll leadership roles—plus evidence of cross-border provider consolidation and PE-backed delivery. Keep Robert Walters or Robert Half as a contingency or interim-search partner rather than leading the specialist permanent mandate. roberthalf +3
