Draught exclusion and other insulation

There are several smaller ways homeowners can insulate their property. Often cheaper and easier to implement than measures that involve engineers and building work, here are some things you can do yourself:

Exclude draughts

  • It’s estimated that £30 could be saved each year by draught-proofing windows and doors.
  • To stop cold air entering and warm air escaping, fit draught excluders around all exterior doors, and interior doors where necessary.
  • Buy sealant strips for your doors and consider installing a brush trim to combat bigger gaps and letterboxes.
  • Putty, sealer and sealant strips can be used to block cracks and crevices in window frames.

Invest in soft furnishing and carpet

  • Reasonably priced and easy to install, thermal curtains and blinds will keep in the warm air and reduce draughts.
  • Installing carpeting with adequate underlay can also help prevent heat escaping through the floor.

Seal gaps

  • Filling in the gaps between skirting boards, around radiator pipes and between floorboards will increase insulation. For this you can use a silicone sealer.

Insulate your boiler

  • Ensuring heat doesn’t escape from your boiler will drastically increase efficiency. Padded jackets can reduce heating loss by up to 75%.
  • Lagging your hot water tank and any visible pipes between the tank and boiler could save you around £45 a year.

Help your radiators

  • Ensure that when your radiators are in use, the hot air is free to flow around the room. Remove any surrounding furniture and consider placing foil behind your radiators to reflect heat back into the room.
  • Fitting thermostat valves to control individual room temperatures will help to prevent the heating of rooms that are not in use.
