Carshalton Boilers have once again provided a fantastic service. A seal went on the boiler, so the boiler had to be shut down. The part was ordered immediately, and Leigh the engineer came back 2 days later. Fitted the part and got us up and running again. I have used Carshalton Boilers for over 40 years, they have never let me down. I would not hesitate to recommend them. Consistent, honest and reliable. A pleasure to do business with them

Report
They have today been to service my elderly parents boiler and condemned it without giving them any information or support. They are now left on a freezing cold night with no hot water or heating and they are understandably very concerned as to what happens from here. They serviced the boiler less than 12 months ago with no mention of any issues. The customer service and empathy has been disgusting and I will be certainly be looking for a second opinion. When we got the boiler company out the next day they said it hadnt been serviced properly for years and they shouldnt have condemned it as

Excellent service from Darren who fitted the boiler and John the Electrician. Darren was thorough, knowledgeable, clean and tidy. He kept us updated during the 2 1/2 day installation. Thank you.

Positive:Responsiveness
The problem was an issue with the Gravity fed type system. It took a couple of Visits to get right to the problem but they fitted an expansion tank and the associated pipework, after a survey, took away the old tank in the loft and left it clean and tidy. Credit where credit is due.

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
