Boiler replacement

"I found Gareth as he was recommended by Keston as an approved installer. My boiler broke down in January during one of the coldest weeks. Gareth came on the same day I called. He sent me a quote that evening. I confirmed the next day and he came to install my new boiler the following day. He was on time, tidy and very professional. He did what he said he would do. There were no bad surprises. His price was very competitive. I would use Gareth again and have already recommended him to a friend."


We had a leak on our boiler recently. Flush came round the same day and provided an excellent service to get it all sorted. They were highly efficient and friendly and gave excellent advice on how to manage such situations in the future. I would really recommend them. - Boiler Repair
