Single glazed windows, or those installed before April 2002, could be losing heat and therefore money. Switching to energy efficient windows can save energy and reduce your heating bills by up to £461.00 per year*
The British Fenestration Rating Council states:
'If you live in a single glazed house and install Energy Efficient Windows, you could reduce the energy you use by 0.30 tonnes or 18% - almost reaching the Government target of 20% reduction per household.
Add to this other simple energy saving measures – such as insulating your home and turning down the central heating by 1° C - and you could be making a real impact on reducing your carbon footprint.
