Couldn’t recommend Kieran enough! He came out to replace a faulty washing machine tap for me and had it sorted quickly and with absolutely no fuss. Really friendly, reliable and clearly knows what he’s doing. He explained everything as he went and left everything clean and tidy afterwards. Will definitely be calling him again for any future plumbing jobs. Thanks Kieran! ⭐️⭐️⭐️⭐️⭐️

We had a ceiling leak and needed an emergency plumber asap. A friend gave us Kieran’s number, and he sorted the whole thing so fast. He was punctual, friendly, and really professional, plus his communication was spot on. We were so impressed that we're actually getting him back to do more work for us now. Highly recommend Kieran if you want someone reliable who does a great job!
