Energy efficiency

Doors
Fit draught excluders around the edge of your external doors and add an internal flap to stop draughts through the letterbox. Even the keyhole can let in draughts, so add an escutcheon plate.

Insulation
If you lay down a 150mm (6in) layer of fibre insulation in your loft, you could save up to 20% of your annual heating costs. It will also make the bedrooms 'feel' warmer. Topping up thin layers of old insulation to at least 150mm (6in) is also a good idea.

Hot water tank
Make sure your hot water tank is fitted with an insulation jacket - it only costs around £10.

Radiators
Fit insulated foil sheet behind radiators that are fitted to outside walls. You should also check the system is working at its best by regularly bleeding the radiators of trapped air.

Central heating
A modern combination or condensing boiler is a big money saver if you plan to stay in the same house for the medium to long term. It's also worth updating your heating controls by fitting thermostatic radiator valves. These allow you to heat just the rooms you need and adjust the temperatures precisely.

Advanced timer units for the boiler can cut down on wasted heat by adjusting the on-off times to your needs.

You can even switch to different times for the weekends.

Energy-efficient light bulbs
Compact fluorescent lamps (CFLs) will save you money, cutting electric bills by up to £10 per year. Always turn out the lights when you leave a room.

Windows
Up to 25% of the lost heat in a home is caused by draughty windows. Add draught excluders around the outside edges of window frames and get into the habit of drawing the curtains at night to keep the heat in.

Appliances
Buy energy efficient appliances to lower your electricity consumption. Look at the coding on freezers, fridges, washers and other appliances: 'A' rated machines are much more efficient than 'E' or 'F' rated appliances.
