Do I need planning permission for aluminium sliding patio doors?

Looking to renovate or improve your home? Our aluminium sliding patio doors offer several benefits, including uninterrupted views to the outside and exceptional weather resistance, making them a great addition to any property. Now you’re in the decision-making stage, you may be wondering whether you need planning permission for patio doors.

It’s unlikely you’ll need planning permission to install aluminium sliding patio doors but there are some cases where permission may be required, so we’ve put together a blog which will hopefully answer any questions you may have.

When do I need planning permission?

You will need planning permission if:

  • You’re building something new.
  • You’re making a change to an existing building which exceeds the permitted development requirements.
  • You’re changing the building use (e.g., from commercial to residential).
  • You live in a listed building, in an Areas of Outstanding Natural Beauty (AONB), or a conservation area.

Permitted Development Rights

Permitted development rights allow you to improve or extend your home without applying for planning permission. It’s still a good idea to double check even when you think you don’t need planning permission as they can ask you to tear down any non-approved buildings and it could be costly if you don’t get it when you should have done.

Do I need planning permission for aluminium sliding patio doors?

If you’re simply adding aluminium sliding patio doors to your property by using an existing opening or widening one, then it’s highly unlikely you will need planning permission as it should fall under permitted development. It is worth checking that the area is capable of withstanding extra weight from your new sliding doors and that they don’t affect the principal elevations of your home.

If you’re planning on having an extension with aluminium sliding doors, then we would recommend checking whether you need planning permission for your extension. Most rear and side extensions cannot be more than 4m wide or 4m high, so if your extension exceeds these dimensions, you will need to apply for planning permission.

However, permitted development can have some restrictions, for example, if you live in an AONB, a flat, listed building, or a conservation area you will require planning permission before you can go ahead with any work. For some areas, you will have to work with specific materials for your project to match the character and charm of your surroundings. But there’s no need to worry, we will work with you to ensure your aluminium patio sliding doors perfectly suit the area.
