I cannot praise John and his assistant Steve on their work or customer care. They arrived earlier than expected which was not a problem for me and got straight on with the job. As this involved turning off the gas and water obviously this meant. no heating on quite a cold day As I am at the moment pretty much housebound, John kindly provided me with a small heater which was much appreciated. The job itself was carried out w th the minimum of disruption, and by mid afternoon was completed. John went through the controls with me and explained how to alter the settings. It was about half an hour later when I discovered that the bedroom radiator was only luke warm . I called John who returned within half an hour and sorted out the problem in minutes. if you need a firm you can 100% rely on for the quality of their work and outstanding customer service look no further than Paragas.
