What you need to know

How long have I got to implement a planning permission?  

You have three years to start on your development unless a condition attached to the planning permission says differently. If you haven’t started the development after three years, you will need to re-apply for planning permission.  

Can I get confirmation that a planning permission has started?  

For proof that a planning permission has started within three years, you can Apply for a Lawful Development Certificate

What should I do if planning permission is granted with conditions?  

You need to check the wording of the condition. If needed you should apply for approval of details before you start the development. This is known as ‘discharging conditions’. You can discharge more than one planning condition at a time. 

If you do not agree with a condition attached to your permission, you can submit a removal of condition application. However you will need to provide strong justification.   

You can also appeal against a condition that you disagree with

What if I need to make changes to a planning permission? 

There are two types of amendments you can apply for following the grant of planning permission:

How do I know whether the amendment is material or non-material? 

There are no set guidelines as to what can be considered as non-material or minor material. Each case is assessed on its own merits.  

You can find detailed guidance about both these types of applications. See the ‘Flexible options for planning permissions’ section of the Planning Practice Guidance website
