Aluminium bifold doors are a great choice for those looking to renovate or improve their home. They offer many great benefits including giving you an uninterrupted view of your garden. Whilst you’re debating whether to install aluminium bifold doors, you may be wondering whether you need to ask for planning permission for your new bifold doors.
It is unlikely you will, but there are certain cases where you would be required to apply for planning permission. Hopefully, in this blog we can answer some of your queries.

When do I need planning permission?
You will need planning permission if:
- You’re erecting a new building.
- 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 AONB (Areas of Outstanding Beauty), or a conservation area.
Permitted Development
Permitted Development is a government scheme that allows you to extend or renovate your home without applying for full planning permission. It is important to double check even if you think you don’t need planning permission. It could be troublesome and costly if you don’t get permission when you should have done.
Do I need planning permission?

If you are adding bifold doors to your property by widening the existing opening or creating a new one, it is highly unlikely you will need permission as it should fall under ‘permitted development’. But you may want to check the area is structurally safe and capable of withstanding extra weight from your new bifold doors. Aluminium bifold doors are one of the easiest installations to get approved. As long as the bifold doors don’t affect the principal elevations of your home, then you should be good to go!
If you’re planning on extending your home and including aluminium bifold doors, then it’s best to check whether you need planning permission for your extension. With a few exceptions, rear and side extensions typically cannot be more than 4m long or 4m in height. If you exceed these heights, you will need to apply for planning permission. Even if you don’t, it’s worth contacting your local authority to double check.
There are some restrictions to permitted development. If you live in a flat, listed building, a conservation area, or in an AONB, these will require planning permission before any significant works can go ahead. For certain areas, a property will need to include specific types of material to match the character and charm of the surroundings. We will work with you to ensure our bifold doors match the area.
