My Lords, the new homes we wish to be built must, at the same time, meet our greenhouse gas targets and contribute to lowering fuel bills. It is right that we help to ensure that those homes are financially viable for the people who are going to build them. As the Government have accepted, the on-cost for building homes to this standard is £3,000 for a three-bedroom semi. That figure, as the Government again have accepted, comes from a report in 2014, since when costs have come down dramatically. But we also need to ensure that we help the poorest in our communities to save on their energy bills. It is accepted that introducing these standards would result in a saving of £330 per annum for households, compared to houses built to existing building regulations. Equally, it would save those households any retrofit costs in the future, given that the Government have not ruled out raising building standards.
The Government have said that this is a regulatory burden on the small developer, although I remind noble Lords that these standards were agreed by the industry before they were withdrawn by the Chancellor. This was not the evidence given to the House of Lords Select Committee on National Policy for the Built Environment, where it was made clear that small housebuilders were saying that access to finance and the price of land were the major constraints on housebuilding. Let us be clear: regulations are not always to be seen as a burden. Regulations deliver a level playing field across the housing industry and drive innovation. It is regulations that will cut the fuel bills for the poorest in our community and help us to meet the greenhouse gas targets that this Government committed to so strongly and so welcomely in Paris. It is the job of this House to ensure that the Bills that leave here contain good regulation. That is what this amendment would do. I beg to move.
