What to include in your application

Before you send in your application, please check the national requirements set by the The Town and Country Planning (Development Management Procedure) (England) and the National Planning Policy Framework, and the local requirements, outlined below and in full in the Horsham District Planning Framework.

To find out which information you need to submit, use our Planning application checklist.

National requirements

The Town and Country Planning (Development Management Procedure) (England) Order 2015 (DMPO) requires, as a minimum, the following information for a valid planning application:

  • A completed application form submitted either electronically or in writing on the correct national standard application form
  • The correct fee
  • A location and site plan drawn at a metric scale of 1:1250 or 1:2500 with the site area outlined in red, including all land necessary to carry out the development.
  • The ownership certificate
  • Notices of all owners of the application site
  • Elevation plans, floor plans and section plans if the proposal involved building operations
  • Roof plans are required for loft conversions or dormer windows
  • An agricultural land declaration (where necessary)
  • A design and access statement (where necessary)
  • An Environmental Impact Assessment (EIA) will be required but this usually relates to large scale development likely to have significant effects on the environment. Please check with us if you are unsure
  • Advert details plan, required for all advertisement consent applications

Local requirements

The Local Validation List provides guidance about the level and type of information required to be submitted with a planning application which will are required alongside the national requirements list above. The requirements are proportionate to the nature and scale of your proposal.

Please read this document carefully before submitting your application. Indicative thresholds and criteria are given to help, but please note that not all the information itemised in the local list will be required for every application.

If in any doubt about what information needs to be submitted then please contact the Council for advice. Advice on precise requirements for a specific proposal can also be obtained as part of the Council’s pre-application advice service.

Planning application checklist


Once your application has been submitted, it will be registered and the Validation Team will check that everything that is required to validate the application has been provided.

If information is required that has not been provided, we will get in touch with you or your agent to inform you of this and to explain how the required information can be provided.

Once an application is deemed valid, you or your agent will receive an acknowledgement letter by email (if an email address has been provided) or post. This will let you know the name of the planning officer who will be determining your application.

The opportunity to make significant changes to an application after validation is limited. Revised plans which require re-consultation may not be accepted because the reconsultation may not be able to be carried out and a decision made inside the 8, 13 or 16 week target.

Applicants however may be able to make changes to the proposals and plans to address issues raised by Officers and Consultees if time permits during the process of consideration.

In every case the submission of revised details must be accompanied by a written explanation and schedule clearly setting out the proposed changes. Fresh drawings or modifications that significantly alter the nature or description of the proposal will not normally be accepted after validation. If such a change is unavoidable, the Council may ask for a new application. Where an application has been validated but needs significant alteration to make it acceptable, or where pre-application advice to overcome problems has not been followed, the Council will consider the application as submitted and this may result in a recommendation of refusal. The applicant may, however, withdraw the application and submit a new application for a revised scheme before a decision is made. There is normally no fee for the first such resubmission.
