Boiler Installation, Servicing and Maintenance
I have used WAG Heating without exception since 2019. They have installed two boilers for me in that time and they carry out annual servicing and maintenance on each of them. Leigh responds to WhatsApp requests for service and prioritises his response according to the urgency of the situation. All work has been carried out carefully and thoroughly, and the workforce have due respect when entering the property (i.e. shoe removal without being asked etc). The company keep up-to-date with technical developments and in my experience have always specified a fit-for-purpose and lasting solution.

Leigh installed a new boiler for me in September last year, and I was so impressed with their work that I also had them return this year for the annual service. From start to finish, they’ve been professional, reliable and incredibly helpful. The boiler installation was completed without hidden costs. He took the time to explain everything clearly and cleaned the place once the work was done. I’m confident in his work and would recommend WAG Heating Services to anyone needing boiler installation or servicing. They’ve definitely earned my trust, and I’ll continue to use their services in the future.

Leigh and Stuart from WAG Heating Services helped us fix a problem in our newly fitted bathroom. They came up with a solution and worked professionally and efficiently. I hope to use them again for my other bathroom!

We wouldn't use anyone else. Trustworthy, quick, and a reasonable price. Leigh and his team replaced our whole heating system and boiler. They also helped rectify issues caused by a shoddy builder. Always happy to advise, tidy, and arrives on time. Have used them multiple times and will continue to do so. We use WAG for our annual boiler service as well.

Leigh and Stuart installed my boiler, Nest controller and controls for underfloor heating several years ago and have maintained the system ever since. I have always found their service to be top notch. Everything was explained clearly, costs itemised and works delivered to a high level of quality. They have provided great value and are extremely professional, personable and reliable. I would not hesitate to recommend them.

We had Leigh & his team from WAG over to change our old boiler & put the new one from the kitchen into the loft. Also we had all the radiators changed throughout. The guys were all brilliant & did a great job. Very professional & tidy! Would highly recommend them.
