Energy efficient windows can help reduce heat loss, saving you money in the long term. However, windows that provide a poor level of thermal efficiency will be a source of heat loss.

Ratings range from A – C with ‘A’ being the most efficient.

There are many energy rating schemes for windows, the most widely known being the British Fenestration Rating Council, the British Standards Institute and CERTASS.
