Planning & Infrastructure Bill: Chalk Stream Amendment
Support the Chalk Stream Amendment to the Planning & Infrastructure Bill
Part 3 of the Planning and Infrastructure Bill would allow developers to cause environmental harm to rare habitats such as chalk streams if they pay into a general fund to offset this environmental harm elsewhere. The Bill will imminently return to the Commons after completion of its Report stage in the Lords.
The House of Lords has voted in favour of an amendment to the Bill by the Bishop of Norwich to provide greater protection for chalk streams.
What is the Planning & Infrastructure Bill?
The Planning and Infrastructure Bill is a proposed law introduced to Parliament in March 2025, which aims to speed up the delivery of new homes and infrastructure projects. It includes measures to reform the planning process and streamline the planning process for nationally significant infrastructure projects. Controversially, it also introduces a new approach to prevention of environmental harms by developments.
Part 3 of the Bill introduces a new, entirely unknown approach to mitigation which will significantly weaken our existing environmental protections. It would allow developers to pay into a fund to offset harm, instead of following important rules to avoid harming the environment. Known as the Environmental Delivery Plan (EDP), this approach allows environmental harm caused by development in particular locations to be offset by paying into the fund. However, in the case of rare and locally specific habitats such as chalk stream rivers, damage caused by development in these locations cannot be undone or mitigated elsewhere. The Bill does not explicitly include safeguards for irreplaceable habitats, to exempt them from the EDP approach, leaving them vulnerable to irreparable harm from developments.
Amendment 94: the Chalk Stream Amendment
The House of Lords has supported the amendment by the Bishop of Norwich to provide greater protection for chalk streams in the Planning and Infrastructure Bill.
Rejecting the government’s assurance that they are providing protection, the Bishop of Norwich said: “I am not convinced by [the Government’s] arguments; … Amendment 94 seeks to protect chalk streams, this precious habitat which we are the custodians of. It aims to restore biodiversity and create a planning system that works with nature, not against it. At present, I am afraid, the Bill before us fails to do this for chalk streams.”
The Government now has the opportunity to improve legislation with strong measures to make sure our globally important chalk streams are properly protected as it delivers its growth agenda, including house building and infrastructure improvements.
Please write to your MP today to urge them to support Amendment 94, the chalk stream amendment.
