The 28-day time limit for enforcement notice appeals is frequently missed by landlords who underestimate its urgency. An enforcement notice served by a local planning authority alleging an unlawful change of use (for example, from C3 single dwelling to C4 HMO without planning permission in an Article 4 direction area) must be appealed within 28 days of the date on which the notice was served — the Planning Inspectorate has no discretion to accept late appeals. Missing the 28-day window means the notice takes effect and the landlord must comply with it — typically requiring them to revert the property to its previous use (moving tenants out; converting the property back). Acting immediately on receipt of an enforcement notice is therefore critical.
For planning refusals (where a landlord applies for planning permission and it is refused), the time limits are more generous — 12 weeks for householder and minor applications, or 6 months for major applications — but planning appeals are still complex and benefit from professional input. A well-argued Written Representations appeal by an experienced planning consultant can reverse a refusal on sound planning grounds and avoid the cost and delay of a full planning inquiry.
Planning appeal methods, time limits, HMO-specific issues and grounds for enforcement notice appeal
The three appeal methods, the critical time limits, and when and how enforcement notice appeals work for landlords:
- Appeal methods, time limits and HMO planning specifics: Three appeal methods (England — PINS): (1) Written Representations (WR): the most common and fastest method for planning refusals; both parties (the appellant landlord and the LPA) submit written statements; the Planning Inspector considers all submissions on paper and may visit the site unaccompanied; decision typically within 24-36 weeks of the start of the appeal; suitable for most residential and minor commercial planning refusals including HMO change of use decisions. (2) Hearing: the Inspector holds a round-table discussion with both parties; less formal than an inquiry; more appropriate for moderate complexity cases; typically 36-52 weeks from start; suitable where there are material issues that benefit from oral discussion but not full advocacy. (3) Inquiry: formal hearing with evidence, witnesses and cross-examination; legal representation is typical; used for complex or major development cases; 52+ weeks; legal costs can be significant. Time limits for planning appeals (England): minor/householder applications — appeal within 12 weeks of the decision date; major applications — 6 months from the decision date; non-determination — 6 months from the statutory determination period deadline (usually 8 weeks for minor; 13 weeks for major); enforcement notice appeal — 28 DAYS from service of the notice (the single most critical deadline for landlords). HMO planning specifics: C3 to C4 change of use (3-6 unrelated persons): in England, this is permitted development UNLESS an Article 4 direction has removed PD rights in that area. In Article 4 areas, an LPA application is required. Refused C4 applications are commonly appealed. Key planning policy arguments for the appeal: housing need; lack of harm to residential amenity; LPA's policy not being consistent with national policy (NPPF); the property's suitability for small HMO use; no justification for refusal if comparable C4 uses exist nearby. C4 to sui generis (7+ persons or any HMO in full Article 4 area): always requires planning permission; LPA can and frequently does refuse; appeal available; more difficult to win as sui generis HMOs attract greater policy scrutiny. Wales: appeals go to PEDW (Planning and Environment Decisions Wales); similar WR/Hearing/Inquiry methods; Welsh planning policy (PPW and TAN guidance) applies. Scotland: appeals to DPEA (Directorate for Planning and Environmental Appeals); Scottish Planning Policy (SPP) and NPF4 from 2023 apply; similar process
- Grounds for enforcement notice appeal (TCPA 1990 s.174), costs and practical steps: If an LPA serves a planning enforcement notice, the landlord can appeal to PINS (England) on any of 7 grounds under Town and Country Planning Act 1990 s.174: (a) planning permission should be granted for the alleged breach as it stands — effectively a planning appeal against the LPA's refusal to grant permission; (b) the breach of planning control alleged in the notice has not occurred — for example, the LPA alleges unauthorised C3→C4 change of use but the property has always been used as a multi-person HMO (mixed occupancy can be difficult to establish); (c) the matters alleged do not constitute a breach of planning control — for example, the use is C4 but the LPA says it is sui generis when the correct classification is C4; (d) the breach of planning control is immune from enforcement by reason of the passage of time — 4-year immunity for operational development and change of use to a single dwelling; 10-year immunity for any other change of use (including C3→C4). This is a very important ground: if the HMO use has continued for more than 10 years without enforcement action, it may be immune — gather evidence of the duration of use (tenancy records; utility bills; council tax records in the HMO occupants' names; EPC records); (e) the enforcement notice was not properly served — if the LPA failed to serve the notice on all parties with an interest in the land, the notice may be invalid; (f) the steps required by the notice to remedy the breach are excessive or more than reasonably necessary; (g) the period specified in the notice to comply is too short. Enforcement notice appeal procedure (England): lodge online at the PINS appeals portal within 28 days of service; select WR/Hearing/Inquiry; pay no fee; submit grounds of appeal and supporting representations; LPA responds; Inspector decides. An enforcement notice is automatically suspended (does not take effect) during the appeal — the landlord can continue using the property as before while the appeal is determined. However, if the appeal is dismissed, the notice takes effect from the date of the appeal decision and the compliance period runs from that date. Costs in planning appeals: PINS can award costs where either party has behaved unreasonably — for example, an LPA that refuses permission without sound planning policy justification may be required to pay the appellant's professional appeal costs. Appellants who pursue appeals without reasonable grounds (for example, appealing a straightforward policy-compliant refusal of a hugely oversized development) can also have costs awarded against them. Submit a costs application at the start of the appeal if you believe the LPA has behaved unreasonably; the Inspector decides both the appeal and the costs application in one decision
Frequently asked questions
How long do I have to appeal a planning enforcement notice?+
Only 28 days from the date on which the enforcement notice was served — this is an absolute statutory deadline with no discretion for late appeals. If you receive a planning enforcement notice alleging unlawful use of your property (for example, HMO use without planning permission in an Article 4 area), you must lodge an appeal with the Planning Inspectorate within 28 days. The notice is automatically suspended while the appeal is being determined, meaning you can continue the current use during the appeal. Miss the 28-day window and the notice takes effect — you must comply or face prosecution. Contact a planning consultant immediately on receiving an enforcement notice.
What is the time limit to appeal a planning refusal for an HMO conversion?+
The time limit to appeal a planning refusal depends on the type of application: for householder and minor applications (including most HMO change of use applications in Article 4 areas), the appeal must be lodged within 12 weeks of the LPA's decision date. For major applications (10+ dwellings or 1,000m²+ development), the limit is 6 months. Appeals are lodged with the Planning Inspectorate (England) or PEDW (Wales) via their respective online portals. Written Representations is typically the most appropriate method for HMO refusal appeals — decisions typically take 24-36 weeks.
Can I appeal if the council claims my HMO use is time-barred by enforcement?+
Yes — if the alleged breach of planning control (such as a C3→C4 change of use) has continued for more than 10 years without enforcement action, you can appeal on the ground that the breach is immune from enforcement under TCPA 1990 s.174(d). Gather evidence demonstrating that the HMO use has been continuous for more than 10 years: historic tenancy agreements; utility bills in multiple tenants' names; council tax records; EICR or gas safety certificates from that period; planning correspondence. A Lawful Development Certificate (LDC) application to the LPA (or appeal to PINS if refused) is often the best route to formalise an established HMO use.
What does it cost to appeal a planning decision?+
Lodging a planning appeal with the Planning Inspectorate (England) or PEDW (Wales) is free — there is no appeal fee. However, the costs of preparing the appeal (planning consultant; architect; solicitor) can be significant. For Written Representations appeals, a planning consultant typically charges £2,000-£5,000 for a straightforward case. More complex appeals requiring expert evidence are more expensive. If the LPA has behaved unreasonably in refusing permission or the way it has handled the case, you can submit a costs application — if successful, the LPA must pay your reasonable professional costs.
