Live in UK Civils since 2023. Three years of audited data through a single platform. Two industry awards. Zero leakage. The model works at scale — and the case for taking it across UK Construction, Ireland and Europe is no longer theoretical.
Group revenue €2.75bn. Pre-tax profit up 62% to €58.1m. The acquisition of Farrans extends UK infrastructure capability. AstraZeneca Dublin, Astellas Tralee, Moderna Oxfordshire, and four data-centre programmes across Sweden, Netherlands, Denmark and Croatia. The temporary labour exposure across that footprint is enormous. The assurance gap is bigger.

The benchmark. Every check below is operational at Sisk UK Civils today — replicable to UK Construction and Farrans-acquired entities from day one.
Three full operating years. £6.88M of audited spend. Two industry awards. Zero leakage. UK Civils since 2023 — the case study other contractors are now asking about.
The production database, exported. Every requisition, assignment, timesheet, and charge — running through one platform.
A VMS that delivers tables is a database. The Sisk × Nutral model delivers intelligence — patterns the site team can’t see, risks before they crystallise, and commercial levers that compound over time. Six worked examples, taken straight from your data.
Every month. Every supplier. Every payslip. The most recent audit (March 2026) is one of 36+ run for Sisk to date.
Chapter 11 ITEPA 2003 lets HMRC transfer unpaid PAYE/NIC debt up the supply chain — to the end client. UK Civils is protected by the existing umbrella PSL of 11 accredited providers. Every other Sisk BU is, today, exposed.
Nutral runs the labour supply chain. Workforce Assured runs the assurance and audit layer. Together they cover every form of temporary labour exposure Sisk faces — agency-supplied or sub-subcontracted — in every market Sisk operates in.
VMS-driven procurement, onboarding, timesheets, payroll audit, supplier management. Best deployed where agency spend is concentrated and recurring — UK Construction, UK Infrastructure (post-Farrans), and Ireland.
A six-strand Ethical Labour Partnership. Pre-mobilisation desktop assessments, integrated worker compliance checks, monthly payroll audits, on-site worker interviews, dedicated in-region advisor, with optional Nutral VMS layer where agency labour is in scope.
Hyperscale fit-out. Posted workers from multiple EU jurisdictions. M&E heavy. Highest exposure to ghost-worker and umbrella misclassification risk. Reference: WA Amazon multi-jurisdiction programme.
Long-cycle pharma builds. SQEP-critical trades. Cleanroom and process specialists. Reference: AstraZeneca Dublin, Astellas Tralee, Moderna Oxfordshire — all profile-fit for tighter agency control.
Where we already operate. Civils, highways, rail, energy. Post-Farrans acquisition the agency labour bill steps up materially. CIS & PAYE risk concentrated here. JSL exposure highest.
Variable ramp-up profile. Trade flow on/off site. Brick, concrete, finishes — high agency churn. Tight onboarding standards key. UK MSP model directly transferable.
NHS & HSE programmes. SC-cleared trades, security checks, patient-side restrictions. Vetting standards the highest. WA framework directly applies.
BTR / volume housing pipeline. Heavy use of self-employed CIS — primary false self-employment risk. Sectoral spend leakage typically 8–15%. MSP model captures it.
One in UK Tier 1 contracting. One across five European jurisdictions on data centre programmes. Different problem shapes, same operating model.
Six business units across UKCS. TEPMP. The HS2 BBV joint venture. Sizewell C CWA. Lower Thames Crossing under preparation. Migrated from a fragmented broker landscape to a single neutral, audited, transparent supply chain — using exactly the operating model now running at Sisk UK Civils, scaled up by an order of magnitude.
The architecture works because it’s commercially neutral, technology-led, and built by people who know construction. The same model can run any temporary workforce, anywhere. — Operating principle · validated across 6 BUs
Five jurisdictions, one ethical labour partnership. Multi-tier subcontracting structures, posted workers, agency labour, and migrant workforces — exactly the risk shape Sisk faces on Project Wildcat in Denmark, ZNL in the Netherlands, the Luleå programme in Sweden, and Pfizer Zagreb.
Standard PQQs miss what worker interviews catch. Documents tell you what should be happening. Workers tell you what is. We’ve built a methodology that works in five legal regimes — Sisk’s six is the same problem. — WA delivery principle · multi-jurisdiction programme
Three independent value pools. Sisk gets all three from one partner. The Nutral × Workforce Assured architecture isn’t a procurement saving — it’s a structural risk reduction with a commercial dividend.
The two-stage tender process delivered ~3% straight-through saving on the Civils labour spend — through harmonised margins, removal of broker tiers, and rate normalisation. Same approach scales to UK Construction and Ireland.
Chapter 11 ITEPA 2003 exposure becomes a contractual matter for the supplier, not a balance-sheet item for Sisk. False self-employment risk under CIS is monitored continuously, not annually.
Worker interview programme provides the lived-experience evidence required for credible MSA reporting. WA findings flow into Sisk’s Sustainability Report. Sisk’s 2030 roadmap goals get hard data, not declarations.
Indicative figures based on publicly available Sisk programme footprint and equivalent contractor benchmarks. Actual scope, pricing and commercial terms subject to discovery and joint design.
UK Construction. Ireland. Europe. One conversation. We’ll bring the data, the references, and a structured value-pool analysis tied to your operational footprint. No deck. No pitch. A working session.
