Planning Permission and your Conservatory

01 June 2022

The warmer weather is upon us here in the UK, which usually pushes homeowners towards thinking about new additions to their property. One of these is a conservatory, a small extension added to the front or back of a house that has glass panes for the walls and door. Of course, there are plenty of variations on the design and size of a conservatory, but some may require planning permission.

Building without planning permission

To build a conservatory without planning permission, it needs to meet certain criteria. A single-storey extension like a conservatory can be built without you needing to contact your local council if:

  • • It is no more than 4 metres high (or 3 metres high if it’s within two metres of your property boundary).
  • • It does not cover more than half of your garden.
  • • The highest point is not higher than the eaves of your property’s roof.


When you need planning permission

If you are designing a structure that is larger than what has been outlined above, you will need to contact your local council to ask for planning permission. The criteria for extensions has eased up since 2019, but you cannot build a conservatory that is larger than the above measurements without seeking permission first. If you do and are reported or the council finds out, you could be fined and asked to stop construction or remove the structure.

Though small additions to your home can be achieved without planning permission, it would be best to check with your local authority in your council’s planning department and seek a lawful development certification as proof that your development was legal at the time you built it. This will stop any future issues if someone decides to complain about your construction down the line.

How to get planning permission

To obtain planning permission, you will need to submit a request to your local council. Since 2008, all local planning departments use the same application form, which is a form called 1APP. It can take around 8 weeks to be approved.

Householder planning permission is used for homeowners to gain permission to alter or extend their individual house within their property’s boundary.

A householder application for planning permission in England, for the erection of a larger single storey rear house extension, is £96. Further costs then apply to approve details and the materials that will be used, which is £116 per application.

You’ll also need to take into account any costs for planning drawings, which can be in the thousands. Overall, expect to pay around £2000-£3000 for a modest extension on a domestic dwelling. Planning permission can also expire, so it’s crucial that you finish your project within the timeline to avoid more fees.

When applying, you will be expected to provide several documents and copies of those documents. Contact your local planning department for more information and to begin the process if you need planning permission for a larger conservatory that doesn’t fall within the limitations of a smaller extension.
