Replacing boiler and radiators

Verified Review

Jim is very knowledgeable and professional - excellent and prompt communication before, during (I was overseas when works were being done) and afterwards. I'm very happy with the installation of new boiler and radiators - would highly recommend this company

Couldn't work out why central heating wasn't turning on

Verified Review

Jim was super friendly and helpful, came over a couple of hours after I put my issue on here. He didn't complain about having to clamber over my crap to get in the boiler cupboard, and sorted the issue out super fast. Was really clear and up front about what he was doing which turned out to be really simple. Will definitely call him again if I need to!

Boiler repair

Verified Review

Amazing work by James! He was quick to respond to a breakdown in my boiler and had it up and running again in a couple hours, even when a gas valve replacement was needed. Excellent customer service, he is happy to go the extra mile to deliver an outstanding service

Boiler installation

Jim could not have been more helpful or punctual - he was tidy and considerate and took the time to talk through different options and explain everything. Very communicative and made the whole process very smooth. I would not hesitate to recommend Jim and will certainly be calling him if I have plumbing/boiler issues in the future.
