Planning Permission

Whether you are building an extension, converting a loft or even constructing a house from scratch, you may have to consider applying for planning permission. Here we explain more about planning permission and the process involved in getting it.

What is planning permission?

Planning permission (also known as planning consent) is approval given by your local authority that enables you to make changes to, or start the construction of, a building.

Do I need planning permission?

There are several factors to consider when it comes to deciding if planning permission is needed. The type of property you own, the changes you want to make and its location are just some of the things that will influence the decision.

How long does it take to get planning permission?

It usually takes around 8 weeks for a planning permission application to be reviewed. However, it can take longer for more complex projects or if your local authority has a backlog of applications to process.

Do I need an architect for planning permission?

You do not legally require an architect to apply for planning permission on your behalf. However, due to their experience in handling this part of the process it could make things much easier for you to manage.

This is because they will have submitted countless planning applications for previous projects, so they are more likely to have a good relationship with your local authority and will have a better understanding of what it is likely to be accepted and rejected, saving you time and money.
