Increase Your Home's Energy Efficiency During Repair Work

There are plenty of changes you can make to your home to increase its energy efficiency without resorting to disruptive building work. Our Saving Energy pages can give you more information.

However, if you are carrying out repairs anyway, you could take the opportunity to include some energy-saving measures at the same time. Check first whether you need permission to make these changes (see Consents and Regulations for Energy Improvements).

There are three main areas of your house where you can add insulation:

  • Roofs
  • Walls
  • Floors

If your home needs repair work in any of these areas it's worth considering having insulation installed at the same time. This will be more cost-effective and, if you were considering installing it at some point anyway, can minimise any disruption.

Make sure that the materials you use are apppropriate to the construction of your home. For more information on adding insulation see our Saving Energy: Insulation pages.


Repairs to tackle any damp problems will improve the energy efficiency of your home. However, it's important to check that you're not missing out any areas and that the cause of the damp has been correctly diagnosed. See Understanding Decay.


If your windows or doors need repairing, having them draught-proofed at the same time will be particularly cost effective. It is also worth looking at any other areas of your home that might need draught-proofing. See Draught-Proofing for more information.


If you need to carry out any repair work on your heating system, consider upgrading the boiler to a more fuel-efficient model at the same time. If the work involves taking up a suspended timber ground floor at ground level you could take advantage by adding insulation to the floor structure at the same time. See our guidance on insulating floors.
