Energy efficiency:
Draught-proofing is a cost-efficient and simple way to make your home more energy-efficient.
When a professional draught-proofs your windows, doors, and floors, you can cut your carbon emissions by 215 kg annually. That’s about the same as taking a small car off the road for a year!

How does draught-proofing increase energy efficiency?
Draught-proofing fills gaps and cracks in your home, so any heat stays inside where it's needed. This means you don’t have to use your heating as much, which can:
Save energy.
Lower your bills.
Reduce your carbon footprint.
The cost to install draught-proofing can vary and is based on a few factors:
You can draught-proof your home yourself or have an expert do it for you.
On average, it costs around £250 for a professional to draught-proof an entire home. If you do it yourself, you will just need to pay for the right tools.

FAQ's - Draft Proofing
Draught-proofing is a simple way to make your home warmer and save money. It involves sealing gaps around doors, windows, floors and other areas where cold air and potentially moisture sneak in and warm air escapes 24/7 without any control. It also helps to keep your home dry and prevents problems like mould when ventilation is provided.
Draught-proofing improves comfort and saves the average UK house £30 per year on energy bills. Our advisers can help you find out if draught-proofing is right for your home. They can also connect you with accredited suppliers to get it installed or advise on how you can do it yourself.

How does draught-proofing work?
Draught-proofing works by closing up gaps where cold air enters your home. It is usually done on doors, windows and floors. When you close these gaps, it keeps the heat inside so you don’t need to use as much energy. However, all along the outside walls of the home is worth looking at, including pipes, cracks in render or unused holes. This helps lower your energy bills and makes your home snug. If done well and with the whole house needs in mind, it can also help stop damp and mould from forming, so you can enjoy a healthier home, too!
What does draught-proofing look like and where does it fit in your house?
Windows
Special draught-proofing strips stick around the edges of your windows. These look like rolls of tape or foam and can be matched to the colour of your window frame.
If your window doesn’t open, a tube of sealant can be used instead. Sealant comes in a variety of colours to match your window frame.
Doors
You can draught-proof your doors in a few ways:
One of the easiest ways is to cover the keyhole with a metal cover. This moves around so you can open your door with a key.
You can also use a letterbox flap or brush to stop any draughts.
Draught-proofing strips can be added to the edges and bottom of your door. You can also use foam or brush-like strips, like those used for windows.
Floors
To stop cold air from coming up through your floor, special strips or foam will cover any gaps where the floor meets the walls and between ground floor floorboards.
If there are bigger holes or cracks, you might need to fill them with a paste or putty.
