Half of your bill is likely to be for heating. If you can keep the heat in, you’ll lose less energy.


Here’s how:

Walls

Depending upon the type of walls you have, you could benefit from cavity, solid exterior or interior wall insulation, see our insulation page for more details.

Windows

Benefit from double-glazing, secondary glazing or a thermal seal inside.

Floors

Carpets can help keep in warmth. You can also install insulation beneath floorboards.

Draughts

There are simple measures you can make cheaply with materials from your local DIY shop:

  • Sash windows: foam, metal or plastic draught or brush strips
  • Exterior doors: try brush or hinged flap draught excluders for the base. A letterbox brush and keyhole cover helps too
  • Interior doors: use door brushes or a homemade draught excluder snake
  • Unused chimneys: a chimney balloon will work, remember to remove it in summer or before re-using the fireplace
  • Gaps around pipework: apply silicone mastic, wall filler or expanding foam
  • Floorboards and skirting boards:fill gaps with flexible fillers, clear or brown silicone mastic, decorator’s caulk
  • Cracks in walls: use cement or hard-setting decorator’s wall filler
  • Loft hatches: put strips of draught excluder around the edges of the frame and insulate the hatch itself.

Heating systems

Making sure that your heating system is maintained and working properly will keep your costs down.

Central heating and boilers

Bleed radiators and do not block them with furniture. Use room thermostats, Thermostatic Radiator Valves (TRV)’s & programmers correctly. If you are struggling to understand them, contact our Energy Team or download this useful guide.

Storage heaters

Set correctly (input is for storing heat, output for releasing heat) and ensure heat can flow freely:

  • The output setting of your storage heater should be turned off at night and also turned off when you are out of the room or out of the house
  • Don’t use the boost setting except when you really need the extra heat
  • Avoid using supplementary plug-in heaters – it’s better to turn up the input on your storage heater and store more heat
