If you’re looking to make major changes to an existing building, chances are that you have asked yourself ‘do I need planning permission?’ The answer is more than likely ‘yes!’, but don’t worry, we’ve put together a handy guide on the different types of planning permission that you may need. 

Planning permission is the consent of your local authority on your proposed project and is in place to deter inappropriate development. The council considers all local and national planning policies together with the views of statutory consultees and the local community when dealing with applications for planning permission.

You’ll probably need planning permission if you want to:

  • Build something new
  • Make a major change to your building, such as building an extension
  • Change the use of your building

Whilst gaining planning permission can be time-consuming, it is an integral part of the building process and getting it will save you a lot of stress in the long run. There are different types of planning permission and so it’s important to know which type your project will require before you start.

Outline Planning Permission

Before applying for planning permission for your project, it’s important to know whether this is the kind of proposal that is likely to be approved by the local planning authority; this is where outline planning applications come in.

Outline planning applications are submitted before substantial costs are incurred developing a detailed design of your project. This type of application is a blueprint for your design and allows fewer details about the proposal to be submitted and will not usually require plans.

However, whilst fewer details are needed, your application still needs to provide enough information about the building’s overall proportions, access and effect on the surroundings as well as other aspects, for the council to be able to make an informed decision on the development in principle.

Outline permission is not a permission to start work on site. The permission notice will state which matters have been reserved for later approval. When all of the reserved matters have been approved, your work can begin.

Reserved Matters

If you have been granted outline planning permission, you may, within three years of the outline approval, make an application for the outstanding reserved matters. This application will be made up of the information excluded from the initial outline planning application. Reserved matters will typically include information about the layout, access, scale and appearance of the development.

Full Planning Consent

Full planning consent is the most common type of planning application. This is when you submit the full details for your project including detailed drawings of the site and what it is you are planning to do to the local authority for approval.

Examples of when you would need to apply for full planning consent include:

  • Structural alterations
  • Building in your garden
  • Demolishing an existing building
  • Extending your property (dependant on size)
  • Changing the main use of a building

Retrospective Planning Permission 

If you have made a change to your property that would have required planning permission but you have not had approval, a local authority can request that you submit a retrospective planning application for the work that has already been carried out. 

Once you submit your retrospective application, your local authority will then consider the application in the same way that they would any other application. 

You may secure planning permission retrospectively if your application proposal is considered to be acceptable. However, if this is not the case and permission is refused, then planning enforcement action may follow. Whilst retrospective planning permission can work well for some projects, it’s best to make sure that you have permission before you undertake your build to avoid any unnecessary headaches.
