Do you need planning permission for a conservatory in 2023?

At a time when many householders are considering renovating their property instead of a costly move, one of the biggest questions we get asked is: ‘Will I need planning permission for my conservatory?’ So, here’s a guide about the various rules and regulations around conservatory installation in the UK.

The simple answer is no, you don’t need to submit a planning application provided your conservatory meets certain conditions. If it does, it is regarded as ‘permitted development’ and can be built without permission. However, if the plan for your conservatory goes beyond these conditions you will probably need to apply for permission. At Oakley Green Conservatories, our knowledgeable team is on-hand to assist you with any planning application should it be required.

When won’t I need planning permission?

Some of the planning rules mentioned above include the conservatory width must be within the walls of the original house; the conservatory must cover less than 50% of your land area; the conservatory’s height must be lower than the roof of your existing house; the conservatory must not face on to a road and the conservatory must not including balconies, raised platforms or verandas. These are the main conditions likely to apply to the average single-storey extension.

What about boundaries? How close can a conservatory be to one?

It’s worth checking boundaries very carefully before you start work, as any infringement may be regarded as trespass, causing all sorts of problems. However, if the eaves of your conservatory are less than three metres high and the conservatory doesn’t cover more than 50 per cent of the area around your property, it can reach the edge of the boundary without falling foul of regulations approval.

When does a conservatory need planning permission?

As we’ve mentioned, if your conservatory meets certain conditions you won’t need to apply for planning permission. This is known as ‘permitted development rights’. In some parts of the country, such as conservation areas and national parks, such rights might be restricted, and you may well have to apply for planning permission. If you’re unsure, it’s always a good idea to contact your local authority’s planning department to check.

What happens if I have to apply for planning permission?

Once you’ve checked with your local planning authority, you’ll need to submit an application and, in most cases, you will receive an answer within eight weeks. However, this could be longer.

Is there a cost?

There is. And application fees vary in England and Wales so again you should check with your local authority.


It’s unlikely you’ll need conservatory planning permission as long as you meet all the permitted development rules.
