Excellent domestic boiler replacement job

When our old boiler failed, we found Graham through the Vaillant approved installer web site. Graham was efficient, friendly and very tidy and completed the job more quickly than alternative suppliers. We will use him for all of our future heating maintenance work.

We called Graham after discovering a leak in our existing hot water cylinder. Having isolated the system we found it difficult to locate a plumber and found Graham through the list of approved installers for the replacement hot water cylinder we had decided to fit. Graham responded very quickly to the call, gave us an informed opinion as to the merits of the cylinder we had identified, ordered the items and came to fit it all very promptly. His quote was very reasonable for the extensive work he had to do over two days. Graham is a very professional and amiable person, who thoughtfully goes to great lengths to protect the environment in the home in which he is working. He also takes the time to explain and discuss the work being done and to answer questions. I would fully endorse all the positive comments made by previous reviewers and would not hesitate to recommend him.

Graham fitted and configured the HoneyWell EvoHome controls. After a few emails discussing my requirements, Graham came to visit me at my property. He is extremely friendly and easy to speak to. He listened to everything I had to say and understood what I wanted to achieve. His quote was extremely reasonable and he did not try to misquote like many other installers had. He even bought a long an EvoHome Controller and actuator to test with. On the day of the install, Graham arrived when he said he would. He was very professional and his work was extremely neat and tidy. There was no mess at all. He was very accommodating of my children, he did not mind them watching him work. He even got a conversation out of my daughter and she talks to no one she doesn't know. After the installation, he made sure I was happy with the system and knew how it worked before he left. I would definitely recommend Graham and will use him for any future work.

After my old boiler gave up, I obtained 3 separate quotes for a replacement. Graham visited and came up with several options and in the end I went for a combination boiler. This entailed removal of the old boiler plus hot water tank, expansion tank, pump and associated pipework as well as installation and commissioning of the new boiler. Graham carried out the work to time and quote in a caring and professional manner and I would not hesitate to recommend him to anyone else.

EvoHome installation

We were umming and ahing about if we should go with the EvoHome heating control systems from Honeywell. Graham was one of their authorised installers who I found via the Honeywell website so I gave him a call. He came around to get the feel for the house and to talk about how the system would be configured and on the back of this gave an initial quote. We then went back and forward a few times (not on price but on the configuration), nothing was too much trouble for him, always willing to talk over the options and re-issue quotes. When he came to install the system he was polite as ever and very careful and thoughful in how he installed the control units, making sure we were happy with the location of a couple of bits and leaving everything neat and tidy. He made sure that we knew how the system worked before leaving but was happy to offer any amount of support via email or phone. PS the Honeywell EvoHome system is amazing! Just make sure you get Graham in to install it.

Graham is friendly, kind and courteous. His extensive heating experience and skill allowed him to provide a number of very different options for us to choose from in order to rectify a very oddly-configured heating system in the house we have just moved in to. The quality of his work is excellent, everything is neat and tidy (not to mention functional!). We will definitely be using his services in the future. I highly recommend him, and Interheating!

I have been using Graham and Interheating for over ten years. Whether its a boiler service, gas safe certificate, boiler repair or a full installation they are superb, reliable, courteous, professional and sensibly priced. They have never once in my tenure recommended work that doesn't need doing and always consider the wider implications of the advice given. I would have no hesitation in recommending Interheating as a firm to the public or wider businesses.

Graham gave us a quote that was substantially cheaper than British Gas. This was to replace a boiler, radiator and a few other bits. He included everything in his quote. Unlike some companies who hid additional charges in small print, he did an excellent job and provided good honest advice. I work from home and he was friendly, but also quite and unobtrusive. He was punctual and reliable. I have recommended him to everyone I know and will use him from now on. A good London plumber is hard to find!

I highly recommend Graham and his team. They provide a professional, efficient and friendly service. Graham clearly knows his trade and is happy to explain the work he is carrying out in as much detail as you need. Prices are totally transparent before work commences. We initially called Inter Heating as we were having a problem with our boiler that a previous company had failed to fix. Graham made sure to have a clear understanding of the problem, diagnosed the issue, and fixed the boiler, all in a polite, quick and efficient manner with no drama. We were impressed and have used them ever since.

I have used Interheating & Philip & Graham's services for years. I have used them in my own home, recommended them to friends & family & regularly use them on behalf of my clients at work. I have always found their advice to be helpful & honest, it is vitally important in my job that I trust the advice I am given, before I have to pass it onto my clients & with Interheating I feel secure in doing so. It is not often I feel so secure in recommending a company, their service & skill mean fabulous value for money.
