Highlights
"Stephen found a leak with my shower. The leak had been so bad that we ended up re doing the entire bathroom. Everything looks amazing and I am very pleased. Stephen and Clive were very nice, easy to talk to, have constantly kept me updated with the process, worked very hard and delivered pretty much a whole new bathroom - when possible they even used my old natural Stone tiles (which meant extra effort on their side and would have been expensive to repurcahse) to save the cost. I would wholeheartedly recommend them to anyone."
"Thank you so much to Stephen for the brilliant job fitting a new flush to my toilet, complete with full cistern upgrade, and also unblocking a toilet and sink. Stephen was very quick to respond, and had completed all the work within hours of submitting my request! Friendly and professional, clean and tidy, with the highest quality workmanship, I would be very happy to go to Stephen for any future plumbing or drainage problems"
"Stephen was really responsive and managed to get out to us within a day which was great. He fixed the problem and was very polite in the process. I would definitely recommend him to anyone!"

Smart checks
Before you hire a plumber
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.
