Material and non-material amendments

Any changes that you would like to make to a scheme that has been granted planning permission needs our consent. Non-material amendments are those which we consider to be minor and not material to the decision previously taken. Such amendments must be very small and not change your permission in any significant way.

If the amendments are not acceptable because they are considered to be material changes, you will have to submit a further planning application for a revised scheme and gain a new planning permission.


Examples of material amendments

As a general guide, the following are some examples of what may count as material amendments:

  • The application site area (red line) differs from the original application.
  • The application description differs from the original application.
  • The proposal would result in changes to the appearance of the building.
  • The amendment significantly increases the size of any part of the development.
  • The development moves more than 1 metre in any direction.
  • The height of the building or structure is increased.
  • The amendment locates any part of the development closer to a neighbour.
  • The amendment results in a fundamental change in the design of the building.
  • The amendment changes windows or doors which increases overlooking in any way.
  • The amendment would result in a greater visual intrusion to neighbours.
  • There were any relevant objections which would be compromised by the proposed amendment.
  • There has been enforcement action taken.
