My right hon. Friend raises a very important issue. As we increase the housing supply, it is important that the quality of new build homes continues to improve. We set out in our housing White Paper an ambition and a target of a housing market that works for everyone. We expect developers to deliver good-quality housing. We have already announced our intention for a new homes ombudsman to protect the rights of homebuyers and to hold developers to account. We expect all developers to build their homes to a good quality standard. These are homes that people will be living in for many years. They deserve those standards.
