This was meant to be a simple flush out and radiator change, that turned into a major job of total heating system replacement. The engineer was courteous, caring ( boiler failed on the coldest day of the year !!!), incredibly professional and knowledgable. I can not thank him enough for his determination to get us up and running in the quickest time possible. His integrity ( and that of his staff )is unquestionable and I would thoroughly recommend this company wholeheartedly.
