According to your internal analysis, revealed under a Freedom of Information request on 19 Feb 2020, 145,000 heat pumps are needed a year in our city to make the 2050 government target, and 300,000 a year to meet our carbon neutrality targets. What steps are you taking to achieve this goal?
The installation of heat pumps forms part of the wider retrofitting of London’s building stock and I have developed an extensive programme of activity to deliver this. My Retrofit Accelerator - Homes and Energy Leap programmes are actively supporting retrofit activity and heat pump installation. I am also funding work to help identify the best building typologies for retrofitting heat pumps in existing buildings.
My zero carbon buildings policies are also driving the uptake of heat pumps in new developments. In 2018 there was a substantial rise in the number of developments deploying heat pump technologies, with 44% of referable applications committing to instal them. This trend is expected to continue as the electricity grid decarbonises.
But I alone cannot deliver the scale of uptake required. I have repeatedly called on government to create a regulatory and policy framework to drive low carbon heating that is supported by an appropriate financial package of support. This should now be an extremely urgent priority for the government and whilst, I am pleased to see that in the budget the government has announced an extension to the domestic Renewable Heat Incentive and committed to a new Low Carbon Heat Support Scheme this only provides a very small part of the overall support that will be needed to meet our targets. This assumes London is eligible to apply.
