Dear Paul74 Firstly we are sorry to hear you are disappointed with the service our company offers. I would like to explain that as a company, prebooked work, and due to the large geographical area our engineers cover, it is our policy that the engineer will call to advise when they are about to attend site. We also advise the client of this. The engineer did try to call but no response, he then called our office and we also tried to call you, but no reply. At this point we then instructed the engineer to move to his next job, unfortunately out of your area. The boiler will have several water carrying components and any of them could fail at anytime. We would not be able to comment until we could investigate where the leak is coming from. Parts fitted would be covered under warranty for 12 months. So if leak is related we would cover this, but if unrelated then any repairs would be chargeable. As the new leak happened some 7 months after the original then it may well be a completely different issue Paul, over the weekend we have tried to contact you but without success. We would be happy to discuss your individual case with you to achieve a satisfactory resolution. Our contact details are 01634 372180 within office hours.
