BE WARMER, SAVE MONEY ON FUEL BILLS, FEEL GOOD ABOUT YOUR HOME AND GET A HIGH RETURN ON YOUR INVESTMENT. SAVE UP TO 2 TONNES OF CO2 PER PERSON PER YEAR.
Start with the easier and cheaper ways, like loft insulation, draught-proofing, and secondary or double glazing. This can cut 40 to 50% of heat loss, and the money saved on bills can offer a 7-12% return.
Good draught-proofing will keep you warm, but once fitted you need to keep your home ventilated by opening windows regularly on nice days – or you can fit mechanical ventilation.
The next level is wall and floor insulation. For most homes, external wall insulation is better than internal as it avoids the risk of trapping condensation between the wall and insulation material.
