What documents to I need to make a planning application?
Your planning application must be made up of:
- The necessary plans of the site
- The required supporting documentation
- The completed form
- The correct fee.
The local planning authority will not be able to process your application unless the mandatory supporting documentation has been provided. You can also attach any other relevant documentation which you think will help the local authority determine the application.
What supporting documentation must be provided depends on the application type, development type and local planning authority.
There are two levels of mandatory documents, national and local. If you’re applying online, the service will tell you what mandatory documentation you need to provide and allows you to attach the relevant documents. Most applications will require you to provide a location plan and a site plan.
In addition to the national list, your LPA may produce a list which details any specific documentation that is required to accompany the application. The requirements may vary according to the type of application, i.e. household, full, outline, etc. If you are applying online, this list is available from the supporting documents screen or your local planning authority’s website.

Common Questions
Foundations are required to carry and distribute the load of the building safely. Therefore, all buildings should have adequate foundations. The factors that need to be considered when designing a foundation are:
- Type of soil
- Adjacent structures
- Trees
- Drains and sewers
- Size and construction of the new building
- Ground condition
- Landfill sites
It is advisable to contact a structural engineer or speak to a building control body about plans for new foundations.
A roof window (or skylight) is fitted flush within the slope of a roof, while a dormer projects outward, creating additional headroom and floor space.
Both can be installed under permitted development but must meet specific size and position limits to qualify.
Also consider building regulations for a new dormer, find out more on Planning Portal
The failure to obtain planning permission or comply with the details of a permission is commonly known as a 'planning breach'.
A planning breach usually occurs when:
- A development that requires planning permission is undertaken without the permission being granted - either because the planning application was refused or was never applied for
- A development that has been given permission subject to conditions breaks one or more of those conditions.
If the breach involves a previously rejected development (or the retrospective application fails) the council can issue an enforcement notice requiring you to put things back as they were.
There are statutory time limits for enforcement, these vary based on when the breach took place.
If the breach took place prior to 25 April 2024
- Change of use of a building, or part of a building, to use as a single dwelling house - Enforcement action can no longer be taken once the unauthorised use has continued for four years without any enforcement action being taken
- Operational development relating to building, engineering or mining - Enforcement action can no longer be taken from four years, beginning the date where the operations were substantially completed.
If the breach took place on or after 25 April 2024
- Change of use of a building, or part of a building, to use as a single dwelling house - Enforcement action can no longer be taken once the unauthorised use has continued for ten years without any enforcement action being taken
- Operational development relating to building, engineering or mining - Enforcement action can no longer be taken from ten years, beginning the date where the operations were substantially completed.
Other time limits:
There is no time limit for enforcement on breaches of planning control relating to relevant demolition.
For any other breach of planning control, ten years beginning with the date of the breach. This predominantly applies to changes of use.

Planning permission is not required for internal changes such as changing a bathroom to an accessible wetroom, however, if you live in a listed building, you will have to apply for listed building consent for any significant works, whether internal or external.
Building regulations approval will likely be required for changes to a make a bathroom accessible, specifically when the change will impact the structure of the room, drainage and electrical systems. It is recommended to have work completed by a member of the competent person scheme.
Planning permission is not normally required for steps in a garden, however, permission may be required if the steps are part of a larger project such as a raised deck attached to the front of the house.
If the external steps are attached to the house and a roof is constructed, this will become a porch which has different rules attached. Read full details on the planning rules for porches in our common projects section.
Different rules may apply if you live in a designated area such as a conservation area or if the building you live in is listed.
External steps will not normally require building regulations approval unless they are part of the access to the building. If they are then you must ensure that you do not reduce the level of accessibility to the house.
You should contact your local planning authority for further project advice, alternatively, you can apply for a lawful development certificate for confirmation that any changes you make do not require planning permission.
