How many grant applications and payments have been made since 23 May 2022 when the scheme opened?
Answer (Mayor of London, Sir Sadiq Khan: 21st January 2025
The Department for Energy Security and Net Zero (DESNZ) publish monthly statistics on this scheme and the most recent can be found at https://www.gov.uk/government/statistics/boiler-upgrade-scheme-statistics-november-2024.

Question (Thomas Turrell AM; Bexley and Bromley): 16th January 2025
There is a target of 2.2 million heat pumps needed to reach the Mayor's Net Zero goal, is this achievable and realistic?
Answer (Mayor of London, Sir Sadiq Khan: 21st January 2025
I have always said our 2030 Net Zero target is very ambitious, and I can’t do it alone. It will require the considerable and collective efforts of government, boroughs, and London’s amazing communities, businesses and citizens. The scale of the climate crisis means we owe it to this and future generations to do everything we can.
My London Energy and Greenhouse Gas Inventory was updated in November with the latest data from 2022 and shows a 37 per cent reduction on 1990 levels and a 44 per cent reduction on our peak emissions in 2000.
Whilst this shows progress, I am under no illusion that we are now looking at a very steep downwards trajectory to stay on track with my Accelerated Green Pathway to net zero.
One of the main actions that will support this is the decarbonisation of heat supply in buildings. This will take a considerable upturn in the number of heat pumps being installed, as well as connections to heat networks, between now and 2030.
It will require co-ordinated policy, funding and regulatory support, see MQ 2025/0018, to create a market and sector capable of delivering this level of activity.
None of that is easy or a given, but I will do everything in my power to make it happen.

Question (Thomas Turrell AM; Bexley and Bromley): 16th January 2025
What support do you require from Government to reach a target of 2.2 million heat pump installations?
Answer (Mayor of London, Sir Sadiq Khan: 21st January 2025
As outlined in my Accelerated Green pathway to net zero by 2030, published in January 2022, achieving 2.2 million heat pump installations by 2030 will need a supportive policy, funding and regulatory environment from the national government. This would have included, amongst other things, a national phase out of the installation of new gas boilers.
This would need to be complemented by a package of other measures such as grants, a rebalancing of levies on electricity and gas to better reflect their relative carbon intensity, and ensuring we have the heat pump supply chains and skilled installers in place to support a significant increase in the rate of installations.

Question (Thomas Turrell AM; Bexley and Bromley): 16th January 2025
In your Environment Strategy, there is a flow diagram on page 215 that has ‘city-wide deployment of low carbon heating systems eg heat pumps’ with the date ‘2030s’, this appears to be at odds with your target of 2.2 million heat pumps to be installed by 2030. Which target are you aiming for?
Answer (Mayor of London, Sir Sadiq Khan: 21st January 2025
The flow diagram in the Environment Strategy is from my first term when I increased London’s carbon emissions reduction target from an 80% reduction in 2050 to Net Zero in 2050. The wide deployment of low carbon heating systems in the 2030s was listed as being one of the important activities needed to meet that 2050 target.
I updated the London target to 2030 at the beginning of my second term and published the ‘Pathways to Net Zero Carbon by 2030’ document in January 2022. In my response I chose the Accelerated Green Pathway as my preferred pathway to net zero and that sets the trajectory for London’s decarbonisation.
The ‘2.2 million heat pumps’ is not a target but one of a number of activities listed in the ‘Pathways to Net Zero Carbon by 2030’ document to illustrate the speed and scale of activities required to achieve our net zero in 2030 target.
