Left pensioner without heating or hotwater for 11 months! Sent out engineer in October 2023 said it was "dirty gas". Calor gas replaced ALL the LPG parts including new tank, boiler still, not working. They were contacted a number of times during the 11 months they only came out twice. I had to get involved to support my mother in law. August 2024 they sent out engineer who said he cannot fix it and needs to head engineer so two more weeks wait as he is on holiday. The appointment date arrived but the head engineer did not! The engineer that arrived called the head engineer and was finally able to sort the problem at 11 months of waiting. The boiler has worked fine ever since. So I've asked for compensation for the unusually high bill and received the reply that the boiler was not at fault, there is nothing to suggest the boiler was the problem and here's £75 for a good will gesture. What an insult considering the bill was nearly £500 extra for the year and I would have thought the fact that the boiler started working after they fixed it would suggest the boiler was the problem. One person looked at the complaint and when I asked for it to be escalated to the next level I was told there is no next level! Do not go with Ideal Heating they sell you a product they are not willing to support you with until they absolutely must which mean you could also find yourself without heating or hot water for 11 months with extremely poor customer service.
