If you are looking to cut your energy bills one of the most obvious ways to do this is to trade in your old draughty windows for new double glazed ones, but this is not the only improvement you can make to cut costly fuel bills. According to the government-funded Energy Saving Trust, a fully draught proofed home could potentially save you up to £50 a year. Over time this adds up to a substantial saving, especially if you choose to draught proof your home yourself. The Draught Proofing Advisory Association states that draught proofing is, ‘one of the most self-financing forms of insulation, offering the quickest return on the original investment’.

You may think the task of draught proofing is difficult, but all it requires is for you to take a moment to consider where any unwanted gaps maybe located in your home. You may have become so used to them that you no longer notice they are there. Places to consider include:

  • Under interior doors
  • Letterboxes and keyholes
  • Loft hatches
  • Doors
  • Windows

You could pay hundreds of pounds for a professional to carry out the work for you, but if you are already familiar with DIY then draught proofing your home should not pose a challenge. Even if you have never carried out any DIY before, a visit to a nearby hardware store, or a few minutes spent online is all you need to start saving money on your bills.

Inexpensive draught proofing solutions

Interior door draught excluders

These simply rest in front, fix on, or under interior doors. They can be made from a variety of materials from old-fashioned cushioned fabric ‘snakes’ that rest in front of the gap between the door and the floor, to brushes, which are fixed with small screws to the door itself. Newer draught excluders that are double-sided can be cut to size and easily slid underneath the door when being fitted. All these items can be purchased for under £10.

Draughty loft hatches, doors and windows

Draughts here can easily be fixed with foam weather seal strip. This self-adhesive tape runs along the inside of the doorjamb, takes just a few minutes to apply and only costs a couple of pounds for a roll. Not much of an investment to stop a draughty loft hatch, or the front door from letting in gusts of wind.

Letterboxes and keyholes

Special letterboxes with sprung flaps can be brought for £5 to £10 and usually fit into existing screw holes. Keyhole covers can be purchased from any DIY store and are only a few pounds. These too are easily fitted and should stop your hallway from feeling like a wind tunnel.


Not all holes should be blocked up. Some areas of your home require good ventilation, such as the kitchen, or rooms where condensation is likely to build up like bathrooms and utility rooms. Professional advice should be sort when considering covering gaps or vents in these areas of your home.

As you can see, spending a few pounds and making some small and simple alterations to your home can potentially save you hundreds of pounds in the long run. Furthermore, if you carry out the work yourself, you’ll be earning back the money you spent on draught proofing in no time.
