Why?

About 12%* of the heat is lost through draughts in an average British home. Controlled ventilation also helps reduce condensation and damp by letting in fresh air when needed. Most work to tackle draughts can be done yourself and for very little money. Therefore, this is a cheap way of making rooms more comfortable, easier to heat and also reduces heating bills and emissions.

How?

Draughts happen where there are unwanted gaps in the construction of your home, and where openings are left uncovered. You’ll find draughts in any gaps that lead outside (for example around doors and windows). While it is important to block most of these, be careful in areas that need good ventilation. These include areas where there are open fires or open flues and any rooms where a lot of moisture is produced, such as the kitchen, bathrooms and utility rooms.

Draught-free homes feel comfortable at lower temperatures. This means that by reducing draughts in your home you can turn down your thermostat saving even more on your energy bills. Draught-proofing around windows and doors saves around £20 per year*. If you have an open chimney, draught-proofing your chimney when you’re not using it saves around £15 per year* for a typical gas-fuelled semi-detached property in England.

The costs vary depending on how much and which areas of your home you want to draught-proof.  Professional draught-proofing could cost around £200 for a typical semi-detached property. DIY draught-proofing will be cheaper. If you’re happy carrying out simple DIY tasks, this will be no problem. However, some homes, especially older homes with single glazing, will be more difficult. 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.
