How to Make Changes to My Planning Permission Decision

So your planning permission has been granted, congratulations!

This is usually an exacting process where you and your architect worked closely to deliver plans that you loved and would be passed by the local authority. But nothing is ever set in stone.

Sometimes, you change your mind after speaking to friends and family or you have to seek approval for minor modification because little details arise after starting the construction. But starting again and submitting a whole new planning permission application would be a waste of your time and money.

There must be an easier way?

Yes, it’s possible to make changes to existing planning permission and change approved planning permission. Our handy guide below will show you the easiest ways to make amendments after receiving planning permission.

1. Making a Non-Material Amendment Application

The good news is there is a process for making small changes to planning permission that will not have a major impact on your project. For example, moving a window on an extension further along a wall which does not relate to material planning considerations, i.e. overlooking and loss of privacy. This can be amended with a Non-Material Amendment Application to your council.

This simple solution means you can make small changes to an extension, conversion or new build without the hassle of going through the planning process all over again. The Non-Material Amendment application gives you the power to think about the permission you were granted and see if it all makes sense. Having done that, there might be small parts of the design that you want to amend. This could be for a number of reasons, namely:

• Your architect or builder advised you to make changes
• On reflection, you decided to make small amends to your plans

The process might be drawn out but the fact that you can make small changes to planning permission fairly easily puts you in control of the situation. So if anything needs to be changed then, be reassured that you can always submit an application with your architects’ assistance and have a good chance of success.

However, the changes you make in a non-material amendment must not go against any of the existing conditions. Don’t waste valuable time and money chasing amendments that won’t be granted. Seek professional advice prior to submitting your Non-Material Amendment Application and note that if you’re looking to make planning permission changes that would be classed as material, you need to follow a different process.

2. Making a Minor Material Amendment Application

Some changes to planning permission will have a material impact on the build and the way that it is received. When granting planning permission, the council will consider the impact of your proposed building on your neighbours and the appearance of the neighbourhood. These rules are there to protect everyone.

Your architect will submit very detailed plans to the local authority that will outline exactly what you propose to do. This may or may not be passed in its original form by the authority, and from there you will need to make a decision.

If you want to make a change that would be considered as material, then you need to submit an application to change the permission in one of two ways:

• Modifying an existing permission condition
• Removal or variation of a condition of the planning permission

It’s important to understand what might constitute a minor material amendment so you can see what application you might need to submit. Remember that a minor material amendment is one that impacts on your neighbours or the neighbourhood itself.

For example, moving an extension closer to the boundary is likely to be classed as a material amendment because of the potential impact on your neighbour. If in doubt, speak to your architect so you can make the right application and save time, effort and money.

But here’s the interesting thing: If your existing planning permission does not have a condition known as ‘approved plan’ then you are in a slightly better position. Approved plans mean that you have to work from the plans submitted by your architect to the letter. However, if this condition isn’t part of your existing permission, then you may be able to submit a Non-Material Amendment Application and make the changes without affecting the conditions. This will undoubtedly be a quicker and easier process – with more chance of success.

The Bottom Line on Making Changes to Your Planning Permission

If the planning permission changes you want to make fall outside of those outlined above, then it really is back to the drawing board. Your only option is to then submit a new planning application to seek permission for the design you want.

Luckily, many local authorities are sympathetic to this and allow you to send in a FREE re-submission. This is usually dependent on the following factors:

• It has to be for the same development
• It has to be submitted within 12 months of the original permission
• It doesn’t change the character of the development
• You’re only allowed one ‘free’ re-submission
