High Court Allows Housing on Floodplains Despite Safety Failures

The High Court of England and Wales ruled that housing developments may proceed on floodplains even if they fail the sequential test, a safety measure intended to prevent construction on high-risk land. The judgment allows Persimmon Homes to build 190 houses in north Somerset, despite the site being located in flood zone 3a and the existence of 12 safer alternative sites.

The court determined that planning inspectors have the authority to weigh the wider benefits and lifetime safety of a development against a failed sequential test. This decision overturned objections from the Environment Agency and the North Somerset Council, who brought the case to court to block the development.

Local officials and the Environment Agency argue the ruling creates a dangerous legal loophole. In response, the flooding and flooded communities all-party parliamentary group is campaigning for amendments to the National Planning Policy Framework. The group intends to ask Housing and Planning Minister Matthew Pennycook to change the framework to prevent this ruling from becoming a national precedent for speculative housing applications.
