Planning permission for windows and doors
Planning permission for windows and doors, and other regulations
Planning permission is generally not required when installing new doors or windows to your property, unless yours is a listed property, in which case you may require listed building consent.
You do not need to apply for planning permission for windows and doors, if:
- You are carrying out repairs or minor improvements on them.
- You are installing new windows and doors that are of a similar appearance to the current ones, both in construction and design.
- Windows that are on an upper floor side elevation must be obscure-glazed and non-opening or 1.7 metres above the floor level.
In addition to general doors and windows, you do not have to apply for planning permission if you want to install a skylight. There are limitations, however, which are:
- Skylights may not protrude more than 150mm beyond the roof slope.
- Skylights may not be higher than the highest part of a roof.
- If skylights are located on a side elevation, they must be obscure-glazed.
- If side elevated, the skylight must be non-opening or more than 1.7 metres above the floor level.
As of 1st April 2002, Building Regulations apply to all glazing that is replaced. These building regulations cover energy efficiency, thermal performance, safety, air supply, means of escape and ventilation.
A window that is placed on the exterior of a property is classed as a “controlled fitting” under the Building Regulations, which means that in order for Building Control not to be notified, glazing must be fitted by an individual registered under the Competent Person Scheme. An individual registered under this will be approved to carry out work to Building Regulation standards.
If you choose to install glazing through DIY means or somebody not registered under this scheme, you need to seek prior approval from Building Control.
If you live in a listed building and want to replace the windows or doors, permitted development is allowed, but only if listed building consent is granted. Building Regulations apply to listed buildings. It is a criminal offence to carry out any work on a listed property where listed building consent is required but not granted.
