Appeal against validation requirements
If you do not agree that information we have requested is necessary, you may appeal against non-validation.
The Government has amended the Town and Country Planning (Development Management Procedure) Order 2015 in relation to applications and validation disputes. Statutory Instrument 2013/1238 (Town and Country Planning (Development Management Procedure) (England) (Amendment) Order 2013) introduced a right of appeal (article 10a) against the non-determination of applications.
You can challenge our request for more information by submitting a notice, under article 10a, providing evidence to back up the reason why it is considered that the information is not necessary.
If an apparently valid application is later found to be invalid because of a factual or legal inaccuracy, the original valid date for processing the application will be disregarded. The valid date will be reset once the inaccuracies have been resolved.
