What is the planning approval rate in Norwich?

97.3% of householder planning applications were approved in Norwich over 2025 Q2 to 2026 Q1, from 187 decisions. 5 were refused. These are the council's own statutory returns, not an estimate. Most people guess far lower, which is why plenty of good projects never get submitted at all.

Do I need planning permission for an extension in Norwich?

Often not. Many single storey rear extensions fall under permitted development, a national grant of permission you do not apply for. The Project Calculator will tell you which side of the line your project sits on in about a minute.

How long does planning permission take in Norwich?

91.0% of householder decisions here were made within the eight week target, comfortably ahead of the national picture. Add three to six weeks before that for survey, design and validation. Realistically, expect twelve to eighteen weeks from first call to a decision you can build from.

Is there an Article 4 direction in Norwich?

None have been published for Norwich on the government Planning Data platform, but that is a data gap rather than proof. Check the council's own policy map, because an Article 4 direction removes permitted development rights entirely.

How many applications get refused in Norwich?

2.7%, or 5 in the year. Refusals almost always come down to depth, bulk, overlooking, or a design that reads as bolted on rather than part of the house. Nearly all of them can be built in some form after a redesign.

Figures cover 2025 Q2 to 2026 Q1 and come from the MHCLG district planning application statistics, the returns every English planning authority is required to file. Article 4 and conservation area counts come from the government Planning Data platform. Last refreshed 2026-08-16.

What the numbers actually say

Householder planning in Norwich is far more predictable than most people assume. Over 2025 Q2 to 2026 Q1 the council decided 187 householder applications and approved 97.3%. 5 were refused. That puts it 3 of 45 in East of England on approval rate.

Speed is the other half of the story. 91.0% of those decisions landed inside the eight week statutory target, comfortably ahead of the national picture.

Permitted development here

No Article 4 directions for Norwich have been published to the government Planning Data platform. That is not the same as none existing. Plenty of authorities have directions in force that they have not published as open data, so check the council's own policy map before you commit to a design.

17 conservation areas are mapped in Norwich. Inside one you lose roof extensions under Class B entirely, and you lose the larger rear extension route.

The route most people miss

13 larger householder extension applications were made here in the year. That is the prior approval route which lets a terraced or semi detached house go beyond three metres without a full application, and 92.3% of them got through. It is a genuinely usable route and most homeowners have never heard of it.
