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.
- More information about pre-application advice
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.
- Check the fees schedule
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.
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).
- More information on the Community Infrastructure Levy.
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.
- More information on the Solent Disturbance and Mitigation Project.
In order to comply with the provisions of the Habitat Regulations to ensure that development does not adversely affects the integrity of a European designation, new development which leads to a net increase in residential or hotel units must be subject to an appropriate assessment to demonstrate how mitigation measures will be implemented to achieve nitrogen neutrality.
The mitigation measures must be implemented and effective at the point of occupation of the development, and be legally secured for the duration of the development’s effects (based on Natural England’s published advice, generally taken to be 80 to 125 years).
The requirement applies to any proposal for:
- Class C use (dwellings, houses in multiple occupation, hotels, residential institutions including student accommodation) and also sui generis houses in multiple occupation
- Planning applications (full or outline) and prior approvals
- New development or changes of use
The requirement for mitigation measures is based on the net increase in the number of dwelling units (or equivalent).
In order for the council to conduct an appropriate assessment, the applicant must submit a nitrogen budget and provide the necessary information regarding the efficacy of mitigation measures with their application. View the nitrogen budget calculator on our Sustainability Checklist page. It is currently expected that all affected applications submitted after a Cabinet decision on Monday 13 June 2022 will be expected to demonstrate nitrate neutrality. Further guidance will follow.
