According to your internal analysis, revealed under a Freedom of Information request on 19 Feb 2020, 160,000 homes a year need to be retrofitted with measures like wall insulation to meet our carbon neutrality targets. How will you take steps to achieve this?

To accelerate and build the London market and supply chain for carbon neutral homes, I recently launched my Retrofit Accelerator-Homes programme. This provides Boroughs and Housing Associations with technical expertise to undertake whole house/deep retrofit projects including the fabric of the building and renewable energy technologies. My Energy Leap programme also focuses on reducing energy grid consumption to near net-zero through whole-house refurbishments.

My Warmer Homes programme provides qualifying households with up to £4,000 to improve the energy efficiency of their homes, including those in the private sector. My £500m Energy Efficiency Fund (MEEF) is also providing low-cost financing solutions to London Boroughs and other bodies to delivery energy efficiency and renewable generation projects across London.

However, I do not have powers to enforce and regulate the energy performance of existing buildings in London. Government needs to step up and bring in broader building regulation with effective enforcement, or devolve these powers to me, to allow me to deliver high performance standards. Government must also ensure London receives a fair share of the funding made available for energy efficiency in homes.
