The 50% brownfield discount

For a typical 50-dwelling scheme in West Berkshire, successfully evidencing previously developed land status saves £99,750 in levy. That’s the whole point of the PDL evidence workflow — the statutory definition (any building on the site since 1 July 1948, excluding agriculture) is broader than the local brownfield register, and most sites qualify in full or in part when historic OS maps and aerial imagery are reviewed.
