A new round of funding worth nearly £11.5 million to expand a programme that makes homes and public buildings in London more efficient has been announced.

The cash will be used to install energy-saving measures across the capital, with improvements including LED lighting, boilers, insulation and double glazing.

So far more than 400,000 homes and 350 public buildings including schools, hospitals, libraries and town halls have been retrofitted as part of Mayor Boris Johnson’s Retrofitting Programme.

He said: “We need to do everything possible to make the most of our resources, reduce carbon emissions and create a more secure, cost-effective and sustainable heat and power supply across London.

“Retrofitting older homes and buildings has a pivotal part to play in this while also helping to save us all money on fuel bills.”
