Because of our plan, half of homes now meet the Government's 2035 energy performance certificate band C goal, a significant jump from 14% in 2010. In 2010, low-cost measures were targeted, with 960,000 installations. In 2022, funding shifted to high-cost measures to benefit low-income households and less-efficient homes, resulting in approximately 200,000 installations last year.

The hon. Gentleman did not acknowledge that we have moved from 14% to 50% because of the actions of a Conservative Government. To answer his question directly, we are allocating around £20 billion to clean heat and energy efficiency over this Parliament and the next, which will benefit his constituents. That includes our Great British insulation scheme, worth £1 billion, which will deliver insulation measures to around 300,000 of the country's least energy-efficient homes, saving them £300 to £400 each year by March 2026.

I know mathematics is not a strong point for the Labour party, but I will go over the figures again: 14% to 50% over the course of the last three Parliaments, delivered by the actions of this Conservative Government. We have a plan to continue to deliver for the least well-off in those homes that need more energy efficiency measures. As I just said to the hon. Member's colleague, we are allocating £20 billion to clean heat mechanisms over this and the next Parliament, and we are going to continue to deliver for the British people.

We recently announced further details of the £6 billion extension that will be allocated from 2025 to 2028. This will support an extra 500,000 homes—prioritising those who need it most, but including new build—and is on top of support for 700,000 families to install improvements through the Great British insulation scheme and the energy company obligation by March 2026.
