Excellent Boiler Service

Our boiler failed us and Shane came to upgrade & install a new boiler - his honest advice saved us a lot of money & his expert installation was perfect, he flushed and cleaned all the radiators and had everything working wonders. He came recommended to us and would definitely recommend to others. Thank you Helen
