Contributions from housing developers see around £7 billion a year invested back into communities, building more homes and vital infrastructure, such as schools and hospitals, and helping to deliver more than 30,000 affordable homes last year. But, as my hon. Friend has raised with me a number of times, the system is still too long-winded and complex. To fix that, we will introduce a flat rate, non-negotiable single infrastructure levy. As set out in the “Planning for the future” White Paper, that will accelerate house building, aim to raise more revenue than under the current process and deliver at least as many on-site affordable homes. We will publish more details on this soon.
