Draught-proofing cost and savings
The low-cost measures that seal gaps around doors, windows and floors, and the modest but quick heating saving they deliver.
Draught-proofing seals the unwanted gaps that let cold air in and warm air out, around doors, windows, letterboxes, floorboards and unused chimneys.
It is one of the cheapest measures and can be partly done yourself, though a professional job covers more of the house.
Typical UK cost

Payback
Because it is inexpensive, draught-proofing is one of the fastest measures to pay for itself.
