Cavity wall and loft insulation, although unseen, can save up to 1/3 of your heating costs. Although you may have loft insulation, if it was installed a number of years ago, it may well be of inadequate thickness (less than 100mm), and topping up to a minimum of 250mm is essential for real economy. Loft insulation should be installed which allows proper ventilation from outside with walkways to tanks and areas of the loft that need regular access.
Cavity wall insulation is an effective energy saving measure which is promoted by DEFRA as one of the most cost effective ways of improving energy efficiency in the home.
