How Do I Know if I Need Planning Permission for a Conservatory?

Building a conservatory can be one of the best ways to create more space and extend your home. However, it’s not always as simple as just being able to build a conservatory onto the back of your home; you may need planning permission, but how do you know whether that’s the case or not?

Whether or not you need planning permission could depend on what it is you’re thinking of doing, as you are able to build certain types of structures without having to obtain planning permission at all. We understand the confusion this can cause for people, and that’s why we’re here to help you understand what it is you can do, and what you will need planning permission for. 

The reason behind planning permission is to take into consideration the visual and aesthetic effect an extension will have on the building and the surrounding buildings, so whether planning permission is required or not will depend on your conservatory project’s specifications. Essentially, in order to build a conservatory on your property without planning permission, you will need to make sure that it doesn’t impact negatively on your neighbours; although your neighbours will still be told and can raise objections if they have any, as per the Neighbour Consultation Scheme

The UK law was updated in May 2019 to provide us with a much more relaxed take on obtaining planning permission for such as a conservatory or a single-storey extension, as these should now fall under the permitted developments of your home. The law now states that:

  • Terraced and semi-detached home can make additions of up to 6m without obtaining planning permission.
  • Detached homes can now add large structures of up to 8m without obtaining planning permission.

According to the Planning Portal, established by the UK Government, you can build a conservatory onto your home as long as it fits within the following guidelines:

  • No more than half the area of land around the “original house” would be covered by additions or other buildings.
  • No extension forward of the principal elevation or side elevation front a highway.
  • No extension to be higher than the highest part of the roof.
  • Single-storey rear extensions must not extend beyond the rear wall of the original house by more than eight metres if a detached, or more than six metres for any other house.
  • If the house is in Article 2(3) designated land or a Site of Special Scientific Interest, this limit is reduced to four metres if a detached house, or three metres for any other house.
  • Maximum height of a single-storey rear extension of four metres.
  • Extensions of more than one storey must not extend beyond the rear wall of the original house by more than three metres or be within seven metres of any boundary opposite the rear wall of the house.

Before starting the construction process of your new conservatory, we would always advise that you check the specifications to ensure that your conservatory will fall under the permitted developments, and will not require applying for planning permission. If you’re unsure about anything, please speak with your conservatory installation team to discuss your options and give yourself peace of mind.
