Apply for planning permission

COVID-19 Service Update

Updates due to coronavirus

We are able to manage the planning application process and all other electronic communications but face to face meetings are cancelled until further notice.

Last updated: 14 September 2021

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.

From 1 September 2021 our local validation requirements for planning applications will be changing, as agreed by the Planning & Rights of Way Panel on 11 February 2020. Check what documents you need to supply from 1 September 2021.

Apply for planning permission

You can apply for planning permission either online or by post.

Applying for planning permission online, 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.

Any applications that are made invalid, or where the additional information requested is not submitted within the time frame given, will be returned in the post along with 25% administration cost taken from the planning fee.

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:

There are also National and Local Validation checklists for planning applications.

Apply for planning permission

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 (SDMP)

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.

Apply by post or email

You also can apply by post or email if you wish. To do this, download the appropriate planning application form from the Planning Portal website. Fill this form out and email or post it, along with the correct supporting documents, plans and notice, to:


Address: Infrastructure Planning and Development, Southampton City Council, Civic Centre,
Civic Centre Road, Southampton, SO14 7LY

How can I make payment?

If you have submitted your application via the Planning Portal and you have a portal reference number (starts with PP) then you will need to pay via the Planning portal site.

Otherwise, you can pay for planning applications online.

You will need:

  • Application reference number
  • Site or planning location address (first line and postcode)
  • Credit or debit card

Pay for a planning service

If you unable to make payment by these options, please email quoting the site address and advise you are unable to pay online.

Remember: If you do not use the correct Planning Portal Reference Number (starting PP) and/or the location address of the property for which you are applying for planning permission when making payment, it could delay acknowledgement of your payment and the validation of your planning application, and may also result in further payment requests.
