1. Register with CIS

You must register with the Construction Industry Scheme (CIS) if you or your business uses subcontractors for construction work.

How to register as a contractor

You must first register as an organisation on the Government Gateway. You’ll need your National Insurance number and an email address.

You must then register as an organisation for HMRC online services. You’ll need the unique taxpayer reference number (UTR) for your business and a National Insurance number.

Contractors based abroad that do construction work in the UK must follow a different CIS registration process.
