When ever you begin to think of doing any building works the 1st step is to find out whether you need planning permission. There are certain works that are exempt under some councils so it is always best to speak to your local planning office.
When you need it
You’ll probably need planning permission if you want to:
build something new
make a major change to your building, eg building an extension
change the use of your building
To find out if your project will need planning permission, contact your local planning authority (LPA).
Applying for planning permission
You can apply for planning permission online.
If your project needs planning permission and you do the work without getting it, you can be served an ‘enforcement notice’ ordering you to undo all the changes you have made.
When you don't need it
Some building projects don’t need planning permission. This is known as ‘permitted development rights’.
Building projects that normally have permitted development rights include:
industrial premises and warehouses - though there are some limits and conditions
some outdoor signs and advertisements - though there are special rules around these
demolition - but before you begin you must get approval to demolish from your local planning authority
There are other projects that might not need planning permission, eg projects that will have no impact on your neighbours or the environment. If you think this could apply to your project, check with your Local Planning Authority.
