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

To ask His Majesty's Government whether the brownfield land register includes an assessment of the impact of the level of contamination on the viability of the land for development.

The Town and Country Planning (Brownfield Land Register) Regulations 2017 require local planning authorities to prepare, maintain, and publish a Brownfield Register. When including land on the register, local planning authorities must consider that land is suitable, available, and achievable for residential development. This will involve assessing a range of factors and constraints including any known land contamination and viability issues.
