Do Construction Workers Need a Written Statement?
Employees and workers on a construction site need a written statement of employment particulars under Section 1 of the Employment Rights Act 1996, in the same way as staff in any other sector. This applies whether someone is directly employed by a housebuilder, a labour supply agency, or a specialist trade contractor, provided they meet the legal definition of employee or worker.
What causes confusion in construction specifically is the Construction Industry Scheme, or CIS. CIS is a tax scheme: it governs how a contractor deducts money from a subcontractor's payments and passes it to HMRC. It is not an employment status test, and registering someone under CIS, or verifying them through HMRC's system, does not by itself decide whether they are entitled to a written statement.
📌 The short answer
If someone is your employee or worker, give them a written statement, whatever their tax arrangement. If someone is a genuinely self-employed subcontractor running their own business, they fall outside the requirement, and CIS deductions do not change that answer either way.
