Amending an application after the decision has been made

Whether your application has been permitted or refused, there are certain steps you may wish to take to amend it.

If your application has been approved, the degree to which you wish to amend the original application will have a bearing on the type of application you need to submit to us in order to make those changes.

The application types are typically a non-material minor amendment, a material minor amendment, a variation of condition or a full planning application.

Non material amendments

Where the overall dimensions of a building do not change,  there are no changes to any windows or doors, and the changes to not conflict with any conditions attached to the original permission we may consider changes as a non-material amendment.

For example this might include minor changes to an area of hanging tiles on a building, internal changes, or some minor changes to hard landscaping such as the positioning of a path.

Minor Material Amendments:

Where the dimensions of a building are not changed by more than 10% and the description of the development in the original permission has not changed then we may consider changes as minor material amendments.

For example if permission was granted for " a single storey rear extension" which on the approved plans was 3m wide, we would be likely to consider an increase in width of up to 3.3m as a minor material amendment. 

However, we would not consider the addition of a dormer window in the roof that was not included in the original application as a minor material amendment.

Please note

These are only guidelines, and each case will be considered in the context of the original approval.
