With energy prices going through the roof, and winters forecast to get colder it’s a good time to think about how to renovate your house to keep your energy bills down.

Replace draughty windows and doors

If you’ve got ill-fitting, draughty old windows and doors, you could be paying for heat that’s going straight out the window.

According to the Energy Saving Trust changing from single to double glazing could save you around £170 on your energy bills. They’ve developed a calculator to work out how much you could save.

There’s also a lower carbon footprint; typically, 680kg less CO2 is generated.

Seal gaps in the floorboards

If you’ve got stripped floorboards you could be losing as much heat as if you had the window open Cold air naturally circulates below ground floor floorboards, and the small gaps between boards in an average-sized room add up to the equivalent of a small window. Just filling gaps between floor and skirting boards will save around £20 – and 100kg of CO2 – annually, paying for itself in less than a year.

Draught-proof the front door

Draught-proofing outside doors can save a lot of heat and will only cost you a few pounds. There are four main things to think about:

  •  the keyhole – buy a purpose-made cover that drops a metal disc over the keyhole
  •  the letterbox – use a letterbox flap or letterbox brush
  •  the gap at the bottom – use a brush or hinged flap draught excluder
  • gaps around the edges – fit foam, brush or wiper strips like those used for windows

Over time, and with the extremely wet weather we’ve been having, your front door can warp and may need to be replaced. For maximum heat efficiency, and security, look for one with double glazing, and integrated security locks. And check that’s it’s guaranteed for at least 10 years.


Whilst not as efficient as double glazing for keeping in the heat, shutters can cut down draughts and add the perfect finishing touch to your windows. They’re also great for security when you’re out.
