What to check when hiring plumbers in Welwyn
MyTrustedTraders ranks on independent public evidence. No ads, no paid placement. Use these checks alongside the evidence on each profile before you decide who to contact.
- Agree the call-out fee, the hourly or fixed rate, and whether parts are charged on top, in writing, before an emergency plumber starts. Out-of-hours overcharging and 'while I'm here' add-ons are common complaints.
- Be wary of a plumber who, on a first visit, says your whole system or boiler must be replaced. Get a second opinion and an itemised quote (parts and labour separately) before agreeing to major work.
- Gas and boiler work is a separate, regulated trade, not general plumbing. Make sure anyone working on a gas appliance is specifically registered to do gas work, and ask to see that registration before they start.
- For the water-regulations side of plumbing, a WaterSafe-approved plumber is vetted, qualified to the water regulations and insured. You can check yours or find one free at watersafe.org.uk.
- Look for consistent reviews across several named sources, not one polished profile.
