Draught-proofing is one of the cheapest and most effective ways to save energy – and money – in any type of building.

Controlled ventilation helps reduce condensation and damp, by letting fresh air in when needed. However, draughts are uncontrolled: they let in too much cold air and waste too much heat.

To draught-proof your home, you should block up unwanted gaps that let cold air in and warm air out. Saving warm air means you’ll use less energy to heat your home, so you’ll save money as well as making your home snug and warm.

How much could you save by draught-proofing?

Draught-proofing around windows and doors could save you around £45 a year*. If you have an open chimney, draught-proofing your chimney when you’re not using it could save around £65 a year*.

Draught-free homes are comfortable at lower temperatures – so you may be able to turn down your thermostat, saving even more on your energy bills.

 DIY or professional?

Draught-proofing costs will vary depending on how much and which areas of your home you want to draught-proof.

Professional draught-proofing could cost around £225 for your whole house*. DIY draught-proofing will be cheaper.

If you’re happy carrying out simple DIY tasks, draught-proofing will be no problem. However, some homes, especially older homes with single glazing, will be more difficult to draught-proof.

Professional draught-proofing is likely to save more energy because the installer will know exactly the right materials to use and where to use them.
