“Had a burst pipe on a Sunday evening and Darren was at our door within 40 minutes. Fixed it quickly, mopped up the water, and even checked the rest of the pipework while he was here. Absolute lifesaver. Would recommend to anyone.”

“McAlister fitted our new Worcester boiler last month. From the initial quote to the final inspection, everything was professional and on time. The price was competitive and they handled the warranty registration for us. Really impressed.”

“We had our entire bathroom ripped out and refitted by Darren and his team. They were here every day at 8am sharp, kept everything tidy, and the finished result is stunning. Genuinely exceeded our expectations.”
Sinéad O.
“Called about a leaking radiator valve. They talked me through a temporary fix over the phone so I could stop the drip, then came out the next morning to replace the valve properly. Honest and helpful — they could have charged me for an emergency call but didn't.”

“We've used McAlister for everything — boiler service, new bathroom, outside tap, even unblocking the kitchen sink at Christmas. They're our go-to for anything plumbing. Reliable, friendly, and always leave the place spotless.”
