Heat, bills and EPC
What it does for your heat loss, bills and EPC
Draughts carry warm air straight out of a home, and thermal bridges create cold spots where heat bypasses the insulation. Sealing and fixing them reduces heat loss and makes rooms feel warmer, while controlled ventilation keeps the air healthy and the fabric dry.
See the EPC points and savings for your home in the EPC plannerU-value before and after, typical heat and bill saving, and EPC points — worked out for your property.Price

Questions
Pipe, tank and cylinder insulation: your questions answered
Why insulate pipes and tanks?
Insulated hot pipes and cylinders keep heat where it's needed, and lagging pipes in cold lofts protects them from freezing.
What are radiator reflector panels?
Panels fitted behind radiators on external walls to reflect heat back into the room.
Can pipe insulation be added to another job?
Yes — it's usually done alongside loft or heating work.
