I thank my noble friend. He is right, to the extent that we recognise the constraints. We spent a lot of time early in government identifying what they were, working with the sector. We expect housebuilding activity to double in four years, but the supply of construction materials would need to increase by only about 20% to meet the demand, because housebuilding makes up only about 20% of the construction sector. We expect demand for construction products primarily used in housing, such as bricks, and green tech, such as PV panels and heat pumps, to increase at a high rate, and we see that as an opportunity for great British innovators to get going and improve the supply chains with us.
