What are the best things I can do to save energy in my home?

Answer:

Insulation
• Did you know that nearly 50% of the heat lost from an average house is through loft spaces   and walls?
• By insulating these areas not only can you reduce your fuel bills, you can also make your   home warmer
• By installing loft insulation to a depth of at least 270mm (10"), you could save over a third   of your heating costs
• If your home is un-insulated, up to a third of your heat can be lost through the walls
• Insulating cavity walls provides one of the biggest energy savings in the home, reducing   heat loss through the wall by up to 60%.

Heating
• Upgrading your gas central heating could save you up to 40% on your heating bills (based on a 3   bed semi-detached house)
• Replacing a 15 year old boiler could save you a third on your heating bills
• By upgrading heating controls, you will improve the efficiency of your heating system and can cut   heating costs by up to 17%
• By fitting a full controls package you could save £100-£130 per year.

Glazing
• Around 20% of the heat lost from an average home occurs through the windows. By fitting   double glazed low emissivity with integral draught sealing this can be reduced by more   than half
• Replacing the single glazing in a typical semi-detached house with low e double-glazing   can save £80 to £100 per year.
