Building a conservatory, glass extension or orangery is a great, relatively low cost way to increase the appeal, size and value of your home. Before you begin installing your new conservatory, it’s important to find out whether you need planning permission.

Do I need planning permission for a conservatory?

The short answer is, it depends. - In many cases conservatories are classed as permitted developments, which means that they don’t need planning permission, as long as you meet the following conditions:

All conservatories (orangeries or glass extensions):

 Must not cover more than 50% of the size of the original house
 Must not be built fronting a highway
 Must not include any verandas, balconies or raised platforms
 Must not be higher than the highest part of the existing roof 

 Must not be more than four meters high

Conservatories built on the side of a proper must not:

 Be wider than half the width of the original house

 Have eaves higher than three meters if within two meters of a boundary

Conservatories built to the rear of the property must also not:

 Extend more than three meters beyond the rear wall of an original attached house and not more than four meters if it's a detached house 

 Have eaves higher than three meters if within two meters of a boundary

In addition, planning regulations for conservatories in World Heritage Sites, Areas of Outstanding Natural Beauty, Conservation Areas and National Parks, state that you must not:

 Clad the exterior walls of there property or conservatory

 Install a conservatory on the side of your property

Planning permission for a conservatory on a listed building?

If you live in a Listed Building, you should always ask your Local Building Authority whether or not you need planning permission for conservatories.

Ignoring planning regulations for conservatories can result in a £5,000 fine and having your conservatory altered or even demolished. You should also be aware that your conservatory needs to adhere to the latest UK building regulations.
