## Before you hire a plumber
_What to check when choosing this kind of trade — general guidance, not a claim about this business:_
- 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.
- Look for consistent reviews across several named sources, not one polished profile.
- Check any verified credentials, and that the business details independently check out.
