Do You Need Planning Permission for a Conservatory?

Currently, around 18% of homes in the UK have a conservatory — that’s around 1 in 5 households.

This is a fairly high number, but it’s not overly surprising due to both the aesthetic and functional benefits of this additional living space. And with summer fast approaching, there is no better time of year to consider adding a conservatory to your home.

That being said, if you are considering building a conservatory on your property, it’s a good idea to find out what is involved, and in particular, whether you need planning permission.

What is Planning Permission?

In the UK, if you want to build or modify the use of your land or buildings, you need to first obtain planning permission.

Planning permission takes into consideration the visual and aesthetic effect of any new building or extension on existing homes in a particular area. This is not to be confused with building regulations, which are the minimum standards of design, construction and alternations to any buildings.

You can build some structures without applying for planning permission and often conservatories and single-storey extensions can fall into this category.

Do Conservatories Need Planning Permission?

Unfortunately, there is no universal response to this question. Whether you need to apply for planning permission for your conservatory will depend on the exact specifications of your chosen conservatory.

Fortunately, for those who are looking to build a conservatory in 2020, the UK government relaxed the laws concerning conservatories as they wanted to help homeowners to improve upon their homes rather than have to move to bigger properties.

The UK law now states that you can:

  • Create additions up to 6m without planning permission (on terraced and semi-detached homes)
  • Add large structures of up to 8m without planning permission on detached homes

However, it is worth noting that your neighbours can still object to your plans under the “Neighbour Consultation Scheme”, so it is advisable to talk to them if you are planning to build a conservatory. It is also advisable to try and choose a design that is in keeping with the area.


On a related note, you can now build a conservatory without planning permission as long as:

  • It is no higher than 4m or 3m if within 2m of a boundary
  • Your chosen conservatory does not take up over half of your garden
  • Any side extensions do not take up more than half of the total width of your home
  • The roof ridge of the conservatory is not higher than the eaves of your property’s roof
