New PAYE rules for labour supply chains that include umbrella companies are now one of the clearest compliance warnings for construction businesses, recruitment agencies and end clients using temporary labour.
GOV.UK guidance says the rules apply to new and existing labour supply chains, money paid to workers on or after 6 April 2026, agencies that contract with end clients to supply workers, end clients where there is no agency involved, and umbrella companies employing workers.
The practical change is direct. Where an umbrella company employs workers, the agency or end client is responsible for making sure PAYE is operated correctly. HMRC says it can recover underpaid PAYE from them if the umbrella company has not paid the correct amount.
That moves the issue beyond "which umbrella provider are we using?" and into a much harder question: can the labour supply chain prove that payroll, worker status and payment deductions are being handled correctly?
For construction, this matters because temporary labour chains are often fast-moving. Workers can move through agencies, umbrella companies, payroll providers, subcontractors and site managers before anyone sits down to check whether the structure is clean. That is exactly where risk builds.
Why it matters
Construction employers and labour users cannot treat umbrella compliance as somebody else's admin anymore.
The government's wider policy paper on umbrella company market reform says the measure is aimed at recruitment agencies using umbrella companies, end clients using umbrella workers where there is no agency, and umbrella companies processing worker pay. It also says the policy is designed to tackle non-compliance, protect workers from unexpected tax bills, and stop non-compliant operators undercutting businesses that follow the rules.
That is the commercial point. Bad payroll practice does not just create tax risk. It distorts pricing, damages worker trust and makes compliant businesses compete against suppliers who are only cheaper because they are not carrying the same obligations properly.
For recruitment agencies, the danger is obvious. If the agency controls which businesses enter the labour supply chain, HMRC expects the agency to take that responsibility seriously. Accreditation, supplier familiarity or a low margin will not be enough if the tax has not been accounted for correctly.
For end clients, especially in construction, engineering and labour-heavy work, the risk is practical. A project may need workers quickly, but speed does not remove responsibility. The business still needs evidence showing who supplied the worker, who employed them, who operated PAYE, what checks were done and what records support the decision.
For workers, the issue is even simpler: they need to be paid correctly, taxed correctly and protected from the fallout of non-compliant arrangements they did not design.
Practical takeaway
Businesses using temporary labour should treat the new rules as a reason to clean the labour file before HMRC asks for it.
The immediate checks are:
Map every labour supply chain where umbrella companies, agencies or third-party labour suppliers are involved.
Confirm who has the contract with the end client and who is legally responsible for PAYE checks.
Keep records of umbrella company due diligence, not just names on an approved supplier list.
Check worker payslips, deductions and assignment paperwork where risk is higher.
Review whether any non-UK element exists in the chain and whether extra checks are needed.
Make sure recruitment, payroll, finance and site/operations teams are working from the same supplier record.
Keep evidence of why a supplier was approved, when it was reviewed and who signed it off.
Build an escalation route for unusual deductions, worker complaints, low-margin labour pricing or unclear employment status.

Conclusion
The new PAYE rules make one thing clear: labour supply chain compliance is no longer optional background admin.
For construction businesses, recruitment agencies and end clients, payroll risk now follows the chain. If the umbrella company gets PAYE wrong, the agency or end client may be the one HMRC pursues.
The businesses best protected will be the ones that can show their checks, records and supplier decisions clearly.
The weak position is "we trusted the umbrella".
The strong position is "we checked the chain, kept the evidence and know who owns the risk".
