My noble friend will be aware of the boiler upgrade grant scheme, which was just launched in May. That will provide capital grants to support the installation of low-carbon heat technologies away from fossil-fuel heating. As for how long it will take to replace all those heat boilers, it will take time because, as my noble friend says, the task is enormous—but we are investing £6.6 billion over the course of this Parliament to improve energy efficiency and decarbonise heating.
My Lords, can the Minister assure the House that future government initiatives for reducing greenhouse gas emissions from buildings will also include climate adaptation measures such as addressing overheating and poor indoor air quality, as recommended by the Climate Change Committee?
The noble Baroness makes a very good point. These questions are really for the Department for Levelling Up, Housing and Communities, but the Government are committed to the new home standards and there is a review of building regulations under way, which is probably the best route, rather than legislation.
