    1. Insulate your loft

    A quarter of heat is lost through the roof in an uninsulated home. If your loft has no damp or condensation problems, it’s a fairly easy job. use rolls of insulation, fitting between joists, then add a second layer across the joists. Look for the insulation’s ‘r’ rating – go for 6.1r upwards.

    2. Wrap cylinders and pipes

    Hot water pipes exposed? You’re wasting money and hot water by not giving them ‘jackets’ – foam tubes that cover the exposed pipes between your hot water cylinder and boiler. Find out your pipe diameter before buying.

    3. Insulate behind radiators

    Fit self-adhesive foam strips around windows, or metal or plastic strips with brushes attached. External doors can be a major source of draughts, so cover your keyhole; fit a letterbox flap or brush and use a brush draught excluder at the bottom. Gaps at the sides can be dealt with in the same way as windows.

    5. Fill those cavity walls

    If your home was built between 1920 and 1990 it probably has cavity walls. You could save up to £150 a year on your
    heating bills by having them filled. Find a reputable installer at the national insulation association (

    6. Layer up

    Buy knitted or faux fur blankets and snuggle under them rather than whacking up the thermostat when it gets cold.
    Think about your flooring too – carpets and rugs feel warmer underfoot, especially on bare floorboards.
