This year, important changes to Part L (Conservation of Fuel & Power) of the Building Regulations for England and Wales come into force in April, and will be implemented in October. These changes will make C energy rated windows the minimum standard for replacement windows in existing homes.

Crystal Windows has been offering A and C rated windows for over a year.
