We had our old gas combi-boiler replaced. Our engineer Ben was “The Best”. He did a thorough job survey, explained options for models, sizes and necessary details, sent a written quote within hours. A 10 years manufacturer’s warranty from Worcester-Bosch was included. Due to a malfunction of our old boiler we needed the job done asap. Ben worked out a very acceptable installation date. The work was done within one day as promised. No dirt, no fuzz – you hardly realised his presence.
