Before you apply, we recommend all applicants request pre-application advice. We offer a paid for pre-application advice service. This service will provide you with time to meet with a planning officer and discuss your plans and suggest any improvements that may help your application to be approved.

It is also important to make sure you have all the documents and plans needed to make a planning application. If your planning application is submitted without the relevant documents it may be deemed invalid and this could result in your losing 25% of your deposit.

Applying for planning permission, via the Planning Portal, is quicker and easier. Registration is simple and you can complete your application form online, upload supporting documents and pay the appropriate fee online by credit or debit card, or over the phone.

National and Local Validation checklists (15 April 2015) - Validation checklists for planning applications.

Community Infrastructure Levy (CIL)
All planning applications must provide sufficient information to allow the city council to determine whether the development is liable to pay the Community Infrastructure Levy. Applicants are therefore required to complete the CIL Additional Information Form which must be submitted with their application(s).

Developer Contributions
Sometimes planning permission for new developments will include obligations to help support local services.

Solent Disturbance and Mitigation Project
All applications for planning permission or prior approval for new residential development across the city received after Monday 7 July 2014 will need to provide a means of mitigating the development’s impact upon the ecological importance of the Special Protection Areas within and around the Solent.

Most planning applications require a location plan and a site plan (also known as a block plan), to be submitted as supporting documents. The most common reason for planning applications being rejected is that the accompanying plans are invalid. You can buy plans from one of the Planning Portal's accredited suppliers
