Question to the Ministry of Housing, Communities and Local Government:

To ask the Secretary of State for Housing, Communities and Local Government, what steps she is taking to help ensure that local authorities have adequate (a) powers and (b) resources to (i) adopt and (ii) manage sustainable drainage systems.

The government is committed to securing the delivery of high-quality sustainable drainage systems to help manage flood risk and adapt to the effects of climate change.

The revised National Planning Policy Framework we published on 12 December 2024 amended an existing paragraph regarding incorporating sustainable drainage systems in new development to make clear that developments of all sizes are expected to make use of sustainable drainage techniques where the development could have drainage impacts. These systems should be appropriate to the nature and scale of the proposed development.

We will consider whether further changes are required to manage sustainable drainage systems provision through the planning system when we consult on further reform.

National Planning Guidance is clear that local authorities should be satisfied that all Sustainable Urban Drainage Systems have clear maintenance and adoption arrangements in place for the lifetime of a development.
