Pre-application advice

Please read our information on how we are supporting residents and businesses, as well as information on affected services.


We are dealing with a high volume of enquiries.  Our staff are still working remotely and may be working different hours.

We are still providing pre-application advice and the "Do I need planning permission?" service.  We can provide pre-app advice:

  • as either a desktop only service or
  • an unaccompanied visit plus a virtual meeting or phone call.  This is charged as a pre-app with accompanying site visit.

You will need to submit:

  • a site location map with site edged red to a scale of 1:1250 or 1:2500
  • description/schedule or existing uses on the site
  • a site plan (to scale)
  • correct fee

Please note that we prefer electronic submissions.  Please send it to planning@cornwall.gov.uk.  We will send you an email with your reference number and instructions to pay: Pay for something - Cornwall Council

If you need to submit in hard copy, please send it to:

Cornwall Council Planning, PO Box 676, Threemilestone, Truro TR1 9EQ.

What are the benefits?

Pre-application discussions:

  • save time and money
  • reduce the number of unsuccessful planning applications
  • make sure you provide enough information with an application.

You can use our pre-application advice service before you submit a planning application. This service can include:

  • research the history of the site
  • a site visit if required
  • checks against Council policies and standards
  • a meeting with the applicant if needed. This could be a telephone discussion.
  • checks for further investigations
  • checks for key groups needed for consultation
  • a written response.

Our response will inform whether you should continue with your planning application.

Planning Performance Agreement

A Planning Performance Agreement (PPA) helps manage the planning process. The Local Planning Authority (LPA) and applicant can use it to agree:

  • timescales

  • resources

PPAs are useful at:

  • the pre-application stage
  • the planning application stage
  • the post decision stage
  • combination of these stages

For further information please see our Planning Performance Agreement Charter.

Community Engagement

Planning case officers offer advice on options for finding out local views. This is part of the pre-application or Planning Performance Agreement (PPA) discussions.

Community engagement is good practice and can:

  • identify local issues and concerns
  • inform Members and the public of a proposal early in the planning process
  • help local councils, developers and offers work together
  • show officers pre-application discussions with a developer
  • help developers to shape an application to address community issues
  • make the submission and determination process smoother.

One option is our PACE Forum service.  Information on Pre-application Community Engagement (PACE) including:

  • details of the suitable options
  • how the forums run

can be accessed on using these links:

PACE Forums are not possible for confidential requests for pre-application advice.

We publish pre-application enquiries and responses. Exceptions are:

  • commercially sensitive and
  • confidential information.

We receive requests to disclose information under the:

  • Freedom of Information Act (FOI)
  • Environmental Information Regulations (EIR)

The Council will have to provide this information unless the information is exempt.  We will only withhold information if the information falls under one of the:

  • exemptions (FOI)
  • exceptions (EIR)

These are set out in legislation.

The applicant should complete a pre-application confidential/commercially sensitive checklist. You need to explain:

We will note these views. A final decision on whether the information will be withheld is the Council's.
