Planning appeal methods and time limits

England: Planning Inspectorate (PINS); Wales: PEDW; Scotland: DPEA. Three methods — Written Representations (WR; fastest; 24-36 weeks; Inspector decides on papers); Hearing (36-52 weeks; round-table discussion); Inquiry (52+ weeks; formal; legal representation). Time limits: minor/householder — 12 weeks from decision; major — 6 months; enforcement notice — 28 days from service of notice (critical — cannot be extended). An enforcement notice is automatically suspended during the appeal.

HMO planning and enforcement notice appeal grounds

C3 to C4 change of use (3-6 persons): permitted development unless Article 4 direction applies. In Article 4 areas, LPA application required; refused applications commonly appealed via Written Representations. C4 to sui generis (7+): always needs planning permission. Enforcement notice appeal grounds (TCPA 1990 s.174): (a) permission should be granted; (b) breach not occurred; (c) not development; (d) time-barred — 4-year immunity for operational development; 10-year immunity for change of use including C3 to C4 (gather tenancy records; utility bills; council tax records); (e) notice improperly served; (f) steps excessive; (g) compliance time too short. Costs: awarded against a party that behaves unreasonably; submit costs application at start of appeal if LPA has refused without sound planning justification.
