We had quite a few quotations to do the work. However, Andy stood out as he took time to discuss our boiler needs and came across very well as he took time to explain what available on the narket and indicative costs. Andy is approachable and friendly. He knows his job and wash honest regarding his availability. It was worth waiting for Andy to become available to fit our new boiler. Andy explained the different types and bolier brands to enable us to make an informed decision. He offered a fixed price lump sum quote. Andy cleaned up after his work daily. He installed an intelligent nest for free. I would not hesitate to recommend him. Great Engineer.
