With the advent of the Green Homes Grant, more homeowners than ever are thinking about the benefits of retrofitting their properties. However, it’s increasingly clear that there’s a greater need to address the renovation and retrofit of older properties in the UK above and beyond the funding provided by the Green Homes Grant.

There are near to 30 million homes in the UK and these are responsible for 25% of the UK’s energy use. As more than 98% of these are energy inefficient, with Energy Performance Certificates (EPCs) of C or below, there is a significant need to carry out radical improvements.

The Grand Designs magazine team asks the experts to outline how to push forward with your home’s energy efficiency journey.
