What permitted development does and doesn't cover
Planning Portal makes two high-impact points applicants miss: many householder PD rights do not apply to flats/maisonettes, and designated areas (conservation areas, National Parks, AONB) have more restricted PD rights.
Government householder PD technical guidance adds another: PD rights may be removed by an Article 4 direction or removed via conditions on the property's planning permission.
Check if your property has full PD rights.
PlanWiser's Property Checker shows Article 4 directions, conservation areas, and other constraints that restrict or remove PD rights.

If work is done without permission, people often assume time alone makes it safe. England changed enforcement time limits: government announced the four-year limit was removed and a single 10-year tariff applies to breaches occurring on/after 25 April 2024, with transitional arrangements.
If you need to regularise, Planning Portal explains retrospective planning permission is treated in the usual way and does not guarantee approval, and councils can issue enforcement notices following refusal.
Conditions and post-permission traps
Even when you have planning permission, conditions matter. Many permissions contain pre-commencement conditions and 'no development until' style requirements.
If you breach conditions, you can land in enforcement territory and may need to apply to regularise or discharge. Planning Portal includes 'failure to obtain or comply' as a planning responsibility topic and explains councils can issue enforcement if breaches persist.

These pitfalls cost people thousands in rework, enforcement, or resale problems:
- Assuming PD applies without checking property type (flats) or location (designated land)
- Ignoring Article 4 directions—they remove PD rights in specific areas
- Starting work before discharging pre-commencement conditions
- Assuming retrospective permission is automatic—it isn't; refusal can lead to enforcement
- Not getting an LDC for PD work—buyers and solicitors often want proof
Want formal proof your proposal is lawful?

LDC fee: Around £129 for proposed works (half the full householder fee).
Retrospective application: Same fees as a normal application—around £258 for householder—with no guarantee of approval.
Enforcement: If you're found in breach, you may face enforcement action requiring removal or regularisation.
Decision times: 8 weeks for most applications (13 weeks for unusually large/complex).
