The seven grounds (s174(2))
s174(2) Town and Country Planning Act 1990 — seven specified grounds for enforcement appeal: Ground (a) — planning permission ought to be granted for what is enforced against (planning merits, same test as fresh application); Ground (b) — the breach of planning control alleged has not occurred (factual challenge — works didn't happen, or differ from alleged); Ground (c) — the matters do not constitute a breach of planning control (legal challenge — works permitted development, ancillary use, not 'development'); Ground (d) — at the date of the notice, no enforcement action could be taken because of time immunity (4-year rule operational/dwelling; 10-year rule change of use/condition breach — see [[four-year-vs-ten-year-rule-london-enforcement]] + LURA 2023 change); Ground (e) — copies of the notice were not served as required by s172 (procedural challenge); Ground (f) — steps required to comply exceed what is reasonably necessary to remedy the breach or any injury (proportionality challenge); Ground (g) — period for compliance falls short of what should reasonably be allowed (time challenge — too short to comply). Grounds (a) + (g) most common combination — appeal merits + buy compliance time even if merits fail.
Procedure + strategic considerations
Appeal must be lodged before notice takes effect (28 days from service typically). Appeal automatically suspends enforcement notice pending decision — works can continue to exist meantime, but no new related works permitted. Procedure: PINS s174 appeal portal, fee £0, all grounds + statement of case submitted with appeal. LPA submits enforcement notice + officer report + evidence. Procedure usually written reps (£3–10k consultant); hearings/inquiries for complex cases (£12–60k). Timeline 28–50 weeks. Critical strategic point: Ground (a) requires deemed planning application — PINS charges deemed application fee (£462 householder, higher for larger schemes) at appeal stage. Ground (a) failure means notice upheld + costs typically not awarded. Ground (d) immunity is decisive if proved — case dismissed entirely + Certificate of Lawfulness issued. Builderr practice on enforcement appeals: always plead Grounds (a) + (g) minimum; add (b)(c)(d)(f) where evidentially supportable; never plead unsupportable grounds — Inspector dismisses + costs risk.
