It is possible to make changes after receiving planning permission and there are a number of options for this;
- Non-material amendments - for very minor changes that do not materially alter the size and scale of the development
- Minor material amendments - for less minor changes whose scale and nature results in a development which is not substantially different from the one which has been approved.
- Time limit extensions - to change the expiry date of a planning permission
These are changes that are very minor and do not materially alter the size and scale of the building, including its footprint and would not alter the description of the development or the red edge area of the application. This process only applies to planning permissions and no other forms of planning consents.
Changes need to be 'non-material', wholly acceptable, uncontroversial and be of very limited impact. They will usually relate to changes to the openings (windows and doors), materials, internal alterations, fences and walls, layout of bin and cycle storage and parking spaces, minor changes to the design of a building.
You can apply using a standard form on the Planning Portal website and you can include more than one change on the same application. We will normally deal with these applications within 28 days and notify you of our decision.
Minor material amendments
These are changes that are more significant than the 'non-material' amendments described above and are described as being changes whose scale and nature results in a development which is not substantially different from the one which has been approved.
Requests for this procedure can only be made where the original planning permission has a condition stating that'
'The development permitted shall be constructed in complete accordance with the specifications in the application and approved plans listed below, unless otherwise agreed in writing by the local planning authority'
or similar wording. Otherwise, you will need to first apply for a non-material amendment.
Changes will still need to be minor and may include changes to the building that result in small reductions to its scale, height or footprint but still not alter the description of the development or the red edged area of the application. Changes need to be wholly acceptable, uncontroversial and be of limited impact. Slight increases to the footprint or scale of buildings may be acceptable under this process but only where there is no impact upon neighbouring properties.
