Gas Safe before you call a plumber in Wales
Source: Gas Safe Register · Checked: 2026-10-01 · Wales
If the job involves gas — boiler, fire, cooker, pipework — the person who works on it must be on the Gas Safe Register for that work. A general “plumber” title is not enough.
Before anyone opens a wall
1. Check the engineer on gassaferegister.co.uk for the right categories. 2. Ask for a clear written scope and quote before work starts. 3. Keep certificates and invoices; you may need them for warranties or a sale later.
Evening call-outs
Emergency and evening visits usually cost more than daytime rates — ask what the call-out fee covers before anyone travels.
For what to ask before they set off, see plumber and boiler call-out costs.
If a listing looks wrong or a firm no longer covers your town, report an update.
Common questions
- Does a plumber have to be Gas Safe?
- For gas work, yes. Check gassaferegister.co.uk for the right categories. A general plumber card is not a gas qualification.
- What should I keep after the visit?
- The invoice and any certificate. Landlords need a gas safety record. Warranties often need proof of an annual service.
