Section B - home energy efficiency
For developments that do not require planning permission opportunities to incorporate energy efficiency during refurbishment and extension projects should be prioritised and adhere to the requirements of the Building Regulations, where relevant. There are several measures that should be considered including for example:
- cavity wall insulation
- loft insulation (150mm or more in non-converted roof spaces)
- replacement of boilers rated F or lower to condensing A rated boilers
- heating control upgrades; and
- draft stripping, floor insulation and thermally efficient glazing
You can read advice on retrofit measures commonly proposed in Westminster and where planning permission many be required in our retrofit how to guides.

Retrofitting historic buildings
With over 11,000 listed buildings and structures in Westminster, we recognise the importance of retrofitting the city’s historic building stock to both conserve our heritage and to incorporate measures to address sustainability issues for the future. We encourage retention and retrofitting historic buildings where a sensitive and tailored approach to design and specification is taken which will both optimise energy efficiency and ensure significance of heritage assets is conserved. Our adopted Environment SPD includes a chapter on retrofitting with advice on both small and large changes you can make to reduce the carbon footprint of historic buildings.
