London’s homes and workplaces are responsible for 78% of the capital’s carbon emissions and virtually all will need some level of retrofitting over this decade, the Mayor of London, Sadiq Khan, has highlighted.

He has declared a “retrofit revolution” in London, announcing a new package of measures that will make buildings more energy efficient and tackle the climate emergency.

The capital’s social housing urgently needs upgrading to be as energy efficient as possible, the Mayor said, with improvements including better insulation, low-carbon heat and clean power sources, such as solar energy.

His new Innovation Partnership is intended to make it easier for social landlords and building firms to work together to upgrade ageing homes in the capital. The scheme will link up housing providers and builders through all stages of home retrofitting, from planning through to large-scale delivery.

The partnership has the potential value of £10 billion in retrofit works, the Mayor predicted, and this could create around 150,000 jobs over the decade.

Mr Khan has also been backed by the Department for Business, Energy and Industrial Strategy (BEIS) for London to lead the country by creating a national retrofit centre of excellence to help assist social housing providers gain access to funding for major retrofit projects.

Director of Policy and Places at the UK Green Building Council, John Alker, said: “Improving the carbon performance of our buildings is critical if we are going to meet our net zero goals, and although an enormous challenge it also presents a tremendous opportunity.”

The successful delivery of local retrofit programmes, he went on, will not only improve resident’s quality of life through upgrading the energy efficiency of their homes and tackling the danger of cold and damp, but it can also act as a catalyst for creating green jobs and upskilling the supply chain.
