Tim quoted for the work and not only fixed the problem but identified why the leak had most likely started and resolved that as well. He was very responsive to questions and by exchanging photos via email came to fix the problem already having the parts with him. Making the actual repair work very quick and efficient.
Tim is so good and easy to work with I have asked him to service my boiler, solar thermal system, fire etc. Plus whilst talking to Tim found out that he is very knowledgeable and experienced with alternatives to gas fired boilers so am now discussing replacing the boiler with an air to water system.
Would highly recommend Tim to anyone.
