Doors and draughts
Gaps round doors, windows and floors let warm air out. Sealing them is one of the cheapest jobs in the house.
The short answer
- About £250 for professional draught-proofing of windows and doors in a whole house, and less if you do it yourself
- About £55 a year saved on windows, doors and floors, plus about £45 a year for an unused open chimney
- About five years to pay back at the professional price. Seal the accidental gaps, never the vents
