If you’re thinking about installing the stylish doors, you need to consider whether you’re going to need planning permission.

The application process for planning permission can be a hassle, but you may not actually need it. Adding or replacing doors is one of the less complicated home improvements, so they usually don’t require any planning permission. However, they still need to meet the UK’s building regulations in order to be compliant.

Don’t worry, we’re here to help you work it out.

What is planning permission?

Since 1948, it’s been necessary for new developments to meet certain criteria and have proper permissions in place in order to be deemed lawful. Subject to certain conditions, it can either be granted or refused.

In general terms, you may need planning permission if you want to:

  • build something new
  • make a major change to a building (such as an extension)
  • change the use of your building

Will I need planning permission for my bi-folds and sliding doors?

Changing or adding doors (such as bi-folds or sliding) doesn’t normally require planning permission as it is usually considered a permitted development—particularly if there is no extension built for your doors.

However, these rights can be taken away by the local authority under certain circumstances, for example if your property is listed or in a designated conservation area.

What if I’m building a whole new extension?

If your doors are part of a new extension, then the whole project may also need planning permission, and here are three factors you’ll need to think about:

  • The location of your extension
  • Its size
  • The potential impact it will have on surrounding houses.

If your extension falls within the limits below, then no application for planning permission would need to be made:

  • for detached properties—a single-story rear extension of up to 8 metres
  • for non-detached properties—a single-story rear extension of up to 6 metres.

Consideration for your neighbours will have to be given when building a whole new extension, and this may affect whether or not you are granted planning permission. Let’s face it, your neighbour isn’t going to be best pleased if you’ve blocked out all of their sunlight…

How long does it take to be granted planning permission?

It varies depending on how many planning applications are in the pipeline, but it usually takes about 8 weeks to apply and acquire planning permission if it’s needed. Planning applications for householders cost £172, which is a set national fee.

Of course, if there are any objections then there may be delays in this process. If you are unsure about whether your new doors will need planning permission, and don’t want to waste any time, then we recommend going to your local authority.

Please note that these are just pointers. It’s your responsibility as a homeowner to find out whether planning permission is required for your property. We recommend contacting your local planning authority.
