Those nice people at Ovo Energy have a comprehensive article on their website listing many ways to make your home more thermally efficient.

In answer to the question “How can I reduce the heat lost through windows?” Ovo Energy say “The easy answer is to install double glazing”, but they also offer other useful tips on draught exclusion on letterboxes and key holes on doors, as well as spelling out how much money you can save by installing double-glazing. Ovo Energy also highlight the specialist knowledge required to comply with planning laws covering conservations areas and listed building – expertise that we at County have in-house and are pleased to share with customers free of charge.
