Did you know? In our experience, 9 out of 10 times an older property will get a poor EPC rating (below an 'E') due to an old boiler that is only providing hot water and not acting as the main heating system for the property. Don't get caught out. Upgrading to a decent boiler and heating system will not only save the earth but save you £££ over the long run. Our recommended brands are Baxi boilers and Worcester Bosch boilers, which come with a 5-10 year guarantee, giving you that much needed peace of mind during the cold, harsh winters.
