Question to the Department for Levelling Up, Housing & Communities:

To ask His Majesty's Government what is the total amount of hectares of contaminated brownfield sites.

The figures requested are not held centrally. Brownfield Land Registers (BLRs) are currently the best resource for the amount of brownfield sites in a local authority area that are suitable for housing, irrespective of their planning status.

National planning policy expects local planning authorities to give substantial weight to the value of using suitable brownfield land within settlements; including by supporting appropriate opportunities to remediate despoiled, degraded, derelict, contaminated or unstable land.
