Validation checks all relevant information and fee (where applicable) has been provided. Validation checks applications against the Cornwall Council Validation Guide:

Validation Guide

The guide is made up of:

National Requirements - required by legislation; and

Local Requirements – set by the Local Planning Authority (LPA).

Applicants can use the Validation Guide as a checklist to ensure all the relevant information has been prepared.

Where information is missing the application will be ‘invalid’ and further information requested.

Validation will take no further action until the applicant/agent provides the required information. Validation will return applications after 28 days if the applicant/agent does not provide the information required.

Interactive Mapping

We are not able to share constraint layers for contaminated land on the Intranet mapping.  A third party provides the data which prohibits it publication on our website.

The Business Regulatory Support Team offer a pre-application advice service which may assist.

The above page also gives an indication of validation timescales.

The DMPO defines ‘working day’ as ‘a day which is not a Saturday, Sunday, bank holiday or other public holiday.’ Any applications submitted on a non-working day or after 5pm on a working day will be classed as being received the next working day.

Accredited Agents Scheme

Using an Accredited Agent for householder developments may assist. Accredited Agents have proven to the Council that they can submit accurate applications. These are in line with the validation procedure. Visit the List of Accredited Agents page for further information.
