Great service as always. Where else could you ring at 7.15 am with water coming through the ceiling, panicking. A friendly voice says don't panic I will be there. He was, a new hot water tank fitted and working before lunch. Thanks Silas you're a star

Fantastic service. Extremely knowledgeable and honest. Came out to help us on Christmas Eve and got our clapped out boiler working for Christmas. So glad to have found such a wonderful plumber.
