The rules this checker tests, cited
England’s permitted development limits for a porch, checked against the official guidance on 2026-07-17. Every rule links to its source.
- A porch must not exceed 3 square metres of ground area (measured externally). GPDO Schedule 2, Part 1, Class D, paragraph D.1(a) (opens in new tab)
- A porch must not be taller than 3 metres above ground level. GPDO Schedule 2, Part 1, Class D, paragraph D.1(b) (opens in new tab)
- A porch must be at least 2 metres from any boundary of the house that faces a road. GPDO Schedule 2, Part 1, Class D, paragraph D.1(c) (opens in new tab)
Building Regulations are separate from planning. A porch at ground level under 30 square metres is usually exempt from Building Regulations, as long as the front door between house and porch stays in place and the porch glazing and electrics comply.
If permission is needed: usually a £548 application in England (fees from 1 April 2026, indexed each year, per the official fee guide (opens in new tab)). A Lawful Development Certificate for a proposed project is £274.

Common questions
Do I need planning permission for a porch in England?
Often not: A porch is permitted development if it stays within 3 square metres, no taller than 3 metres, and at least 2 metres from any boundary with a road. Every limit has to be met, the rights apply to houses (not flats), and they can be removed locally by an Article 4 direction or a condition on an earlier permission. A Lawful Development Certificate from your council is the way to be certain.
