Draught Proofing

Draught proofing

Approximately 15% of a household's heat can be lost through draughts, which occur where there are unwanted gaps in the construction of your home and where openings are left uncovered.



Why draught-proof your home?

Draught-proofing is one of the cheapest and most efficient ways to save energy in your home. By draught-proofing your home you will retain more warm air inside, improve comfort and save energy and money.

Draughts are a bit like ventilation in that they let fresh air into your home. Good ventilation is essential as it helps reduce condensation and damp, however draughts are uncontrolled - letting in too much cold air and allowing too much heat to escape. To draught-proof your home you should block unwanted gaps to save warm air and use less energy to heat your home.

Is my home suitable?

A home energy assessor should check the draughts in your home, particularly around windows, doors, pipework, loft hatches, chimneys and floorboards. Generally, if you can feel cold air coming in around your windows and external doors, it means that warm air is also escaping and your home is suitable for draught-proofing.

How much could I save?

Draught free homes are also comfortable at lower temperatures so you could turn down your thermostat, potentially saving you another £65 per year.


When draught-proofing your home, an installer would generally complete all work in one visit including windows, doors (as well as keyholes and letterboxes), chimneys and fireplaces, floorboards, skirting boards and suspended floorboards, loft hatches, pipework, old extractor fans, ceiling to wall joints and cracks in the walls.

They should also ensure that there is appropriate ventilation in rooms where there is a large amount of moisture, such as kitchens and bathrooms, and where there are open fires or flues. The entire installation process will generally take no more than half a day, providing that the areas that need draught proofing are easily accessible.
