It is a pleasure to witness the pride he takes in his work from which, of course, the customer benefits big time! I thoroughly recommended Calderbank Heating! Alec offers an excellent service, he really takes the time to understand your needs and explains the options available to you in order to provide a solution to your heating and plumbing needs. Whether that be a brand new boiler. Highly recommend Alec as a very knowledgeable heating engineer and a skilled plumber. He combines these abilities to produce a solution for a homeowners heating and hot water problems.
