Do I need planning permission for a porch in Fylde?

Usually not, as long as it's under 3m², under 3m high, and at least 2m from the highway. Listed buildings are the exception — they always need consent.

How much does a porch cost?

A porch in London typically costs between £5,000 and £15,000 depending on materials. A simple UPVC porch is at the low end, a brick-built porch with a tiled roof at the higher end.

What is the maximum size for a porch under permitted development?

The maximum ground floor area is 3 square metres, with a maximum height of 3 metres.

Do I need Building Regulations approval for a porch?

In most cases, no. Porches are usually exempt from Building Regulations provided they are at ground level, under 30m², and have glazed walls.

Conservation Areas & Listed Buildings

In conservation areas, the same PD rules apply to porches, but you should use materials sympathetic to the area character.

Conservation areas

Properties in conservation areas often have reduced permitted development rights. Some project types (like side extensions) lose PD rights entirely. An Article 4 Direction can remove additional PD rights.

Listed buildings

Listed buildings (Grade I, II*, or II) have no permitted development rights at all. Any external alteration requires Listed Building Consent in addition to any planning permission. An architect experienced in heritage work is essential.

Check if your property is in a conservation area or has other planning constraints.
