From floor insulation to clever draught-proofing tips, here's the uSwitch guides on making your home more energy efficient with home insulation.

* Figures from the Energy Saving Trust. For loft insulation these are estimates based on insulating a gas-heated, semi-detached home with three bedrooms, showing savings when you insulate an uninsulated loft, and when you top up 100mm of insulation to 270mm. (The recommended depth for mineral wool insulation is 270mm but other materials need different depths.) For cavity wall insulation these are estimated figures based on insulating a gas-heated, semi-detached home with three bedrooms. The installed cost includes a subsidy of around £250 available from the major energy suppliers under the Carbon Emissions Reduction Target (CERT)
