“WAG Heating Services installed a new boiler at my home. They were very professional and completed a really good job, I’m very pleased with the standard of work, they were also very tidy and were respectful of my home. I would not hesitate to use them again and would thoroughly recommend them.”
“Found WAG heating on checkatrade and have not been disappointed with any of their work. Originally fitted a boiler which they had quoted the best price for. Installation was very professional, turning up on time and left everything very tidy. Following this job they also installed a new bath and completed some electrical work in the garden. All work was exceptionally done. Some additional electrical work had to be completed due to some errors by the previous electricians, this work was done without any extra charge. Very impressed with the service and would highly recommend!”

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.

Professional & reliable
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.

Trustworthy, quick, and reasonable
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.

Friendly, reliable and professional service
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.

Excellent work
WAG Heating Service fitted my new boiler a few years ago and regularly service it. Today I asked them to install new Google Nest thermostats so I could control the temperature with my app. They completed this very quickly and cleaned up and left no mess and I’m very satisfied with their work. Excellent company. I do not hesitate to recommend them for any work you may want done.

Great work at a great price!
Stuart did an excellent job converting an old heating system to a modern combi boiler, going above and beyond to ensure old utilities would work with the new higher water pressure. Included in the installation, Stuart flushed the old dirty water from the system which has dramatically increased the speed in which the boilers take to heat up which will no doubt save us money on our gas bill. Friendly and courteous throughout, he took the time to explain how the new system worked which was really appreciated and he even fixed a broken radiator valve for us which had stopped an old radiator from heating up. All the work was completed for the pre-agreed price and to an excellent standard. I'll definitely be getting WAG Heating Services back for future plumbing works and boiler services.

Highly recommended
I contacted WAG Heating Services when I decided to change my old boiler for a Bosch one. After some searching I found that WAG Heating Services were both a local company and a Bosch accredited installer. When I called them, I found Leigh to be very friendly, polite and accommodating when we looked at a date and time for a visit in order to see the site and assess the work to be done. The first visit was by Stewart who was very pleasant and well informed in his responses. The quote arrived promptly. It was straight forward, with the prices for every item clearly marked and it also contained a simple, easy to understand list of other optional items and their respective prices. When I then contacted WAG again to discuss and confirm my choices, Leigh was very kind, patient, knowledgeable and clear in explaining to me the various alternatives I had thus helping me to finally make my mind up. We chose a date for the works to start and they kept to it. Their work was very neat and it was completed in the promised window of time. I whole heartedly recommend their services.
