Umbrella company liability is no longer only a payroll back-office issue. From April 2026, construction labour supply chains using umbrella companies face a sharper question: who is responsible if PAYE tax is not properly paid? While umbrella companies are often treated as a way to simplify temporary worker payroll, London Construction Magazine analysis shows that the 2026 PAYE changes move tax risk closer to recruitment agencies and, in some cases, end clients who rely on umbrella labour.
Quick answer: From 6 April 2026, where a worker is supplied through an umbrella company, the recruitment agency closest to the end client can become responsible for PAYE if the umbrella company fails to pay correctly. If there is no agency and the end client contracts directly with the umbrella company, the end client can carry the liability.
What Is an Umbrella Company?
An umbrella company is an employment intermediary used to pay temporary workers. In construction, umbrella arrangements often sit between the worker, recruitment agency and the contractor or client needing labour. The worker may attend site for a contractor, but the umbrella company may be the employer for payroll purposes.
The arrangement can be useful where workers move between assignments, agencies and projects. But it can also make responsibility harder to see. A worker may think the agency is responsible. The agency may think the umbrella company is responsible. The contractor may think payroll is outside its concern. The 2026 changes make that assumption more dangerous. For construction projects, this matters because labour supply is not separate from project control. The way workers are appointed, checked, paid and recorded affects site compliance, access control and the evidence trail around who was allowed to work.

What Changed From April 2026?
The key change is that PAYE responsibility can move up the labour supply chain. Where an umbrella company is used, the agency with the contract closest to the end client can be responsible for accounting for PAYE and National Insurance on payments made to workers. Where there is no agency in the chain, the responsibility can fall on the end client.
In plain English, the industry can no longer assume that a non-compliant umbrella company leaves everyone else untouched. If the umbrella company fails to pay the correct payroll taxes, HMRC may have a route to pursue another party in the chain. That is why this change is important for construction. The sector uses large volumes of temporary, agency and subcontract labour. Projects often move quickly. Labour can be supplied through several layers. If the payroll chain is not checked properly, a project may carry hidden tax and compliance risk before the worker even reaches the gate.
Where Liability Can Sit in the Chain
| Supply Chain Position | What It Means | Construction Risk |
|---|---|---|
| Umbrella company | Employs or pays the worker through PAYE. | Non-compliance can expose other parties if payroll taxes are not properly paid. |
| Recruitment agency | Supplies workers to the end client and may contract with the umbrella company. | The agency closest to the end client can carry PAYE exposure if the umbrella company fails. |
| End client | The business receiving the worker’s services. | If there is no agency and the client contracts directly with the umbrella company, liability can move to the client. |
| Main contractor | May be the end client for labour supply or may control site access and labour evidence. | Poor labour-chain checks can create financial, tax and audit risk. |
| Worker | Relies on the chain to deduct and pay tax correctly. | Workers may face confusion over payslips, deductions, holiday pay, expenses and who is actually responsible. |
Why Construction Needs to Pay Attention
Construction is especially exposed because labour supply chains are often complex. A worker on site may have been sourced by one party, paid by another and supervised by a third. That creates gaps. If the commercial team does not understand the labour chain, the project may not know where payroll responsibility, worker verification and evidence actually sit.
This is not only a tax issue. It also affects procurement, mobilisation, site access and workforce records. If a project cannot clearly show who supplied the worker, who employed or paid the worker, what card or competence evidence was checked and which contract controlled the arrangement, the project has a weak compliance trail. That links directly to worker verification. A site can check a CSCS digital card at the gate, but that does not automatically prove the payroll chain is compliant. Site access evidence and labour supply evidence need to work together. The site-entry side is explained in CSCS Digital Cards: Can They Get You on Site?.
What Agencies Should Check
Recruitment agencies supplying construction labour should treat umbrella company selection as a compliance decision, not only a commercial arrangement. The agency should know which umbrella companies it uses, how PAYE is operated, what worker deductions are made, how payslips are produced and what evidence can be provided if HMRC asks questions later.
A low-cost umbrella provider may look attractive until the risk lands back with the agency. The commercial saving can disappear quickly if unpaid tax, worker complaints, weak contracts or poor records create liability after the labour has already been supplied. For construction agencies, due diligence should include checking umbrella provider status, contracts, payroll processes, insurance, payslip transparency, worker communication and how quickly evidence can be produced. It is not enough to say “the umbrella company deals with payroll” if the law now allows liability to move up the chain.
What Contractors and Clients Should Ask
Contractors and clients using agency labour should ask more direct questions. Who is supplying the worker? Is an umbrella company involved? Which agency has the direct contract? Who is responsible for PAYE? What records will be available? What happens if the umbrella company fails? Are indemnities, audit rights and evidence requirements built into the contract?
These questions matter before mobilisation, not after a payroll problem appears. Once labour has been used and money has moved through the chain, recovery and evidence become harder. In construction, the best control is usually at appointment stage: appoint the right people, define the chain clearly and make sure the evidence exists before work starts. The same principle appears across construction compliance. Safe delivery depends on early arrangements, competent appointments and clear evidence, not just site paperwork after the event. A wider dutyholder overview is set out in CDM Regulations Explained: What Construction Professionals Need to Know in 2026.
What Workers Should Watch
Workers should also pay attention. A worker paid through an umbrella company should understand who employs them, who pays them, how tax is deducted, how holiday pay is shown, what deductions are made and whether the payslip is clear. If the arrangement is confusing, that is already a warning sign.
Construction workers often focus on the rate advertised by the agency, but the take-home amount can be affected by tax, National Insurance, umbrella margin, holiday pay treatment and other deductions. The advertised rate and the paid amount should be understandable. If the worker cannot work out who is responsible for what, the chain may not be transparent enough. The 2026 changes are aimed at poor compliance in the umbrella market, but they also make one thing clear for workers: payroll should not be a mystery. The worker should be able to see who is paying them, what deductions are made and where to raise problems.
Evidence-Based Summary
Umbrella company liability now matters directly to construction because PAYE risk can move beyond the umbrella provider and into the labour supply chain. From April 2026, agencies and some end clients need to understand who is responsible for payroll tax, how workers are paid and what evidence proves compliance. The practical lesson is simple: cheap or unclear labour supply is no longer just a procurement risk; it can become a tax, compliance and project governance risk.
FAQ: Umbrella Company Liability
What is an umbrella company in construction?
An umbrella company is an employment intermediary often used to pay temporary workers supplied through agencies. It usually employs the worker for payroll purposes and pays wages through PAYE.
Who is liable if an umbrella company does not pay PAYE correctly?
From April 2026, liability can move to the recruitment agency closest to the end client, or to the end client where there is no agency and the client contracts directly with the umbrella company.
Does this affect main contractors?
Yes, where the main contractor is the end client for labour supply or relies heavily on agency and umbrella labour. It should understand the chain and keep clear evidence.
Does a CSCS card prove the payroll chain is compliant?
No. A CSCS card can support worker competence and site entry checks, but it does not prove that PAYE, National Insurance, holiday pay or umbrella deductions are being handled correctly.
What should workers check on umbrella payslips?
Workers should check who is paying them, what deductions are made, how holiday pay is treated, what the umbrella margin is and whether PAYE and National Insurance are clearly shown.
