So I called CBS and explained that my elderly fathers central heating was problematical and the house was cold. Paul the CBS engineer arrived on time and from the first hello was extremely courteous and polite, I explained the issue and he diagnosed the problem, Paul explained the remedy and how he would actually be fixing it which he did within an hour and as well detailed the cost that it would incur. I found Paul again to be a true professional in his field and would have no hesitation in recommending CBS to anyone who requires their services. SJP

Fantastic!!! This was the 3rd company I had attempted to contact this morning following my boiler breaking down during a weather warning with heavy snow. I have twin babies and was so worried for them as the house became so cold so quickly. Their receptionist was so lovely after I broke down on the phone explaining I had twin babies and she rearranged the engineers calendar so someone could come out to us this morning. The engineer was professional and polite and followed all of the covid guidance throughout the appointment. I cannot thank Carshalton Boilers enough for how understanding they were

As a company we found them very helpful and reasonably priced. We had a gas leak in a feed pipe buried in a concrete floor which was not repairable. A replacement pipe was installed above ground very neatly.
Darren who was the engineer that did the installation was polite, helpful, tidy and did a very good job. All in all we would use them again.

Prompt, friendly and excellent value. My boiler has had a few issues and they're always available even with covid going on and it being the middle of winter. Much better than British Gas Homecare, very impressed!
