Make a planning application

Detailed information for specific application types

In addition to information that must be submitted with all planning application types, you may have to provide extra information in specific cases.

The information below gives details of documents that must accompany some specific types of application. Go to our overview of information for specific application types for a summary list.

Existing and proposed site sections and finished floor and site levels

You will only need to provide this with applications that involve a change in ground levels or where the development is proposed next to ground levels that are changing.

On sloping sites you must show how the proposals relate to current ground levels where ground levels may be modified.

Drawings must be at a scale of 1:50 or 1:100, and show a cross section through the proposed buildings. Where a proposal involves a change in ground levels, drawings must show both existing and finished levels. Drawings must include details of floor levels, building height and relationship to site boundaries.

Your plans must also show:

  • how proposed buildings relate to existing site levels and neighbouring development
  • existing site levels and finished floor levels– with levels related to a fixed datum point off site – and also in relation to adjoining buildings

Levels should also be taken into account when preparing design and access statements.

Roof plans

You will only need to provide this with applications where a roof would be created or altered by the proposed development.

Drawings must be at a scale of 1:100 or 1:200, and show:

Agricultural appraisal

You will only need to provide this with applications that propose new dwellings for agricultural workers, or the removal of agricultural occupancy conditions on existing dwellings.

You should include functional and financial evidence that shows there is an agricultural need for a permanent dwelling and there are no suitable dwellings available in the locality.

For removal of conditions, you should be submit evidence that there is no long-term need for an agricultural workers dwelling in the locality. This should show e property has been publicised for sale and let to other relevant interests in the locality.

Air quality impact assessment

You will only need to provide this with applications for developments of 10 or more residential units, or 500 square metres of non-residential floor space within the Air Quality Management Area.

Biodiversity survey and report

You will only need to provide this with applications where the type and location of development are such that the impact on biodiversity may be significant and existing information is lacking or inadequate.

You do not need a biodiversity checklist for:

  • advertisement consent
  • change of use of an existing building
  • internal subdivision of an existing building
  • minor works, such as the erection of a fence, wall or gate, or a dropped kerb
  • a lawful development certificate
  • prior notification of agricultural or forestry development

Where your checklist shows the need for a biodiversity report, the report should assess the impact of your proposed development on wildlife. It should include proposals for mitigation or compensation measures, including the protection of habitats and provision of new habitats.

The report must include an assessment of existing structures or potential natural habitats where they are to be removed or naturally affected by the proposals.

Environmental impact assessment

You will only need to provide this with applications that are likely to have significant effects on the environment.

Your assessment must give details of the likely significant effects.

Regulations set out a procedure for determining which projects should be subject to an Environmental Impact Assessment – go to Planning Practice Guidance: Environmental Impact Assessment for information.

Flood risk assessment

You will only need to provide this with applications for developments on sites of more than 1 hectare in flood zone 1, and all new developments within flood zones 2 or 3.

To the location of flood zones, go to the Environment Agency: flood map for planning.

Your assessment should:

  • set out the risks of all forms of flooding to and from the development
  • show how flood risks will be managed
  • look for opportunities to reduce the probability and consequences of flooding
  • cover the need for safe access to and from the development in the event of flooding
  • include the design of surface water management systems including sustainable drainage
  • take account of climate change

Health impact assessment

You will only need to provide this with applications for developments of 50 or more residential units, or 1,000 square metres of non-residential floor space.

The health impact would also include the safety of an environment.

You will need to measure the wider impact of your development upon healthy living, and the demands that will be placed upon health services and facilities.

Heritage statement

You will only need to provide this with applications for listed building consent, or conservation area consent, or developments likely to affect designated or non-designated heritage assets.

The statement must include:

  • a description of the asset
  • an evaluation of the importance and significance of the asset
  • how your proposal will affect the asset

Where relevant, heritage statements should be supported by photographs, phasing plans, historic photographs or drawings, historic maps and other sources. The amount of information provided should be proportionate to the significance of the asset and the scale of works proposed.

Land contamination assessment

You will only need to provide this with major applications – especially on brownfield sites – and applications that require an environmental impact assessment, or where development is proposed for a site known to have potential contamination issues.

The information must be site specific.

Lighting assessment

You will only need to provide this with applications – except for householder developments – where you propose to incorporate external lighting.

The assessment must include:

  • a layout plan that shows how beams of light will be orientated
  • the proposed equipment design
  • light spillage beyond the property boundary

Parking and access arrangements

You will only need to provide this with applications likely to result in a loss or gain of parking provision.

Your site plan must show existing and proposed:

  • parking
  • cycle storage
  • access arrangements for vehicles and pedestrians

Retail or leisure impact assessment

You will only need to provide this with applications for retail or leisure developments over 2,500 square metres, or likely to have a significant impact on smaller centres, or when they are not in a central location, nor in accordance with a development plan.
