Heatplex were great. They were able to help us out at short notice and get our old and faulty boiler working again. They were knowledge, easy to work with and efficient. Would recommend.

Joe was amazing at sorting our broken heating system, he is incredibly knowledgeable and very friendly. We have found him to be extremely reliable and assisting us with any follow up questions we needed help on. I always recommend him as the go to specialist in the SW London area.

We've used Joe for quite a few years now. He does our annual boiler and gas fire service plus we also used him when we had a leak under our bath and more recently to replace all of the valves on our radiators. We are more than happy with the services that Joe provides. He's responsive, honest, friendly and courteous. I find that it can be difficult to get good tradespeople at the moment, especially ones that are responsive and I'm so glad that we found Joe a few years ago and can rely on him!

Joe did a great job installing my new boiler, quickly, reliably and efficiently. He provided an excellent service, even sending me a how to video (twice after I lost the first one). He puts a lot of care into the job and I would highly recommend him!

I've been using Joe for years - since he was a one man band. He's serviced our own boiler, as well as carrying out service and safety maintenance on our rental property. He's always been honest, good value and very reliable. He's also a genuinely lovey guy. I've recommended him to lots of people over the years. It's been a pleasure watching his business grow over the year and he deserves every success.
