Draught proofing is an easy, cost-effective way to reduce heating bills and carbon emissions.
Windows: Use foam, metal or plastic draught strips, or brush seals for sash windows. Temporary secondary glazing is another option
Exterior doors: Fit brush or hinged-flap draught excluders, fitted along the bottom of the doors. If you don't have a keyhole cover, buy a purpose-made cover that drops a metal disc over the keyhole. Use a letterbox flap or brush, but remember to measure your letterbox before you buy
Interior doors: Cut draughts with ‘snake’ draught excluders, brushes or similar strips of material but remember leave kitchen and bathroom as ventilation is important
Remember to remove the draught-proofing if you decide to light a fire.
Around pipework: Apply silicone fillers or expanding foam as appropriate
Floorboards and skirting boards: Fill the gaps with flexible fillers, clear or brown silicone mastic, decorators’ caulk or similar products
Cracks in walls: Use cement or a hard-setting decorators’ wall-filler
Redundant extractor fan outlets: Old fan outlets may need to be filled with bricks or concrete blocks and sealed from both the inside and outside.
Loft hatches: Use strips of draught excluding material fitted around the edges of the frame, and don’t forget to insulate the hatch itself
Lighting and electrical fittings: Plug the gaps around the fittings with wall-filler
