The registers that matter
- Gas Safe Register: the official list of businesses legally allowed to work on gas in Great Britain, Northern Ireland, the Isle of Man and Guernsey.
- WaterSafe: brings together approved contractor schemes and is backed by UK water companies. Approved plumbers know the water fittings rules and can certify certain work.
- Trade bodies: the Chartered Institute of Plumbing and Heating Engineering (CIPHE), and SNIPEF for Scotland and Northern Ireland.
Differences across the nations
England and Wales follow the Building Regulations and the Water Supply (Water Fittings) Regulations. Scotland has its own building standards and Scottish Water byelaws, and Northern Ireland has its own building and water fittings regulations. The registers above work across the UK, and a good plumber will know the rules where you live.
Water and sewerage companies
Your water company is responsible for the public supply and sewers, and often for shared drains outside your boundary. For low pressure across your street, a leak in the road or a public sewer problem, contact your water company before booking a plumber.
