We’ve put together some tips on how to keep your house warm in winter, and have also asked a few experts for their pointers on staying snug.

1. Seal the skirting boards

‘It may seem like a small change, but using sealant to fill the gaps between the top and bottom of your skirting boards can really make a difference,’ says Claire Osborne, energy expert at uSwitch.

2. Fill the floorboards

Stripped floorboards look fantastic, but the small gaps between the boards can really let cold air in. Try using a silicone-based filler to prevent draughts sweeping in through the gaps.

3. Insulate the doors

Whether your door is old or new, it could still benefit from fitting draught-proofing strips between the door and the frame. This can work for both internal and external doors. For gaps between the bottom of the door and the floor, you can buy a special ‘brush’ or hinged-flap draught excluder.

4. Draught-proof loft hatches

Try installing draught strips around the frame to your loft hatch. The door itself can also be insulated, usually with a polystyrene slab on the upper side.

5. Seal the windows

Here’s another tip from Claire at uSwitch. ‘Draught-proofing strips work well around opening casements,’ she tells us. ‘Draughts also occur in cracks between the window frames and the surrounding walls – it’s worth considering using sealant or putty in these.’

6. Use heavyweight curtains

Thermal-lined curtains can help you keep the cold out more effectively, especially if you have single-glazed windows. At the very least, make sure your curtains are lined.

7. Draught-exclude the letterbox

If you don’t already have a second flap or ‘brushes’ in your letterbox, you could fit either of these, which will help keep the warmth in.

8. Cover the keyholes

You can fit a purpose-made cover that drops a metal disc over the keyhole to prevent any wind whistling through – simple but effective.

9. Install a chimney balloon


This will prevent any unnecessary draughts. If you don’t use the chimney at all, you could consider having it capped by a professional.

10. Repoint any brickwork

Any gaps in bricks on external walls can lead to unwanted and unnecessary wind coming into the home. You can top up mortar between the bricks to stop this happening (though it might be worth considering a professional to do this).

11. Before laying a carpet, fit underlay

The carpet and underlay for flooring that you choose can also make a big difference on your home’s insulation. According to the experts at Carpetright, getting the right underlay for flooring can save you as much as 15 per cent off your energy bills.

Jemma Dayman, Carpet Buyer for Carpetright tells us ‘Underlay is often overlooked, but it’s a really important element of the carpet-buying process. Not only does it insulate, it also provides cushioning, acts as a shock absorber protecting the actual floor itself, and as a sound barrier between floors.’
