Apply for planning permission

Last Modified October 08, 2018

Submit an application online





Before you make your application, please refer to 'Planning Applications - Keeping your personal information safe'  




You can use the Planning Portal to submit and pay for your application online. Around 80% of our applications are submitted online.  There are guidance notes and video tutorials on the Planning Portal website to help you. If this is the first time you have used the Planning Portal service, you will also need to register. Registration is easy and you can complete your application form, upload supporting documents and pay fees online.

Downloading application forms

Some applications are not currently available to submit online. In these cases you can download planning application forms and submit them via email or through the post.

There are a number of different forms for different types of development. It is important you choose the correct form and fully complete all sections relevant to you. Application forms are available online, but please check with us if you are not sure which form to use. Alternatively, you can download the relative planning application form and send it to us.

Ownership and agricultural holding certificates

An ownership notice needs to be completed if you own the property / site.  If you do not own the site, then a notice is to be served to all owners of the application site / property.  Site owners are defined as freeholders or leaseholders with at least seven years of the leasehold left unexpired. The documents can be downloaded from the Planning Portal website.

Application requirements

There are requirements for what must be submitted as part of a planning application. These are set out in the National Planning Practice Guidance Notes (Part 1). For Householder applications, please also refer to the Local requirements and checklist (Part 2).

To process an application we require the information detailed in Parts 1 and 2 above to be submitted with the application. The period for deciding the application cannot start until all the information has been received.

If you are submitting a paper application, please make sure you provide one original plus one copy of the application form, together with one original plus one copy of the plans and supporting information.

If you are proposing a new residential development, please see our new guidance document for Waste storage provision for new Residential developments.


Please provide plans as a pdf, no larger than 5MB each. Please include the type of drawing, site name and paper size in your file titles. 

It is important that you provide accurate drawings with sufficient details to illustrate your proposal to us and the general public. These must be to a recognisable metric scale. Please ensure that you clarify on the drawing the page size you have to print in order to achieve this metric scale.

Site location and block plans

Most planning applications need a site location and block plan showing the site you are planning to work on in red and other land in the same ownership in blue.  You can obtain a plan from:

Community Infrastructure Levy 

New development will be potentially liable for the levy where it creates (1) a new dwelling of any size or (2) net additional floor space of 100m2 or more (in the case of other types of development with a Hertsmere CIL rate). This can include a change of use carried out under Permitted Development Rights. 

All full planning applications and applications for reserved matters (except householder applications for residential alterations and extensions) must now include a completed CIL Additional Information form and the CIL Assumption of liability form. For further information see Community Infrastructure Levy.  Where a building, or a part of a building, on the site has been in lawful use for a continuous period of at least six months within the past 36 months, the existing floorspace may be deducted from the proposed floorspace to arrive at the chargeable area for new residential units. Should new development be undertaken without the need for full planning permission, under permitted development rights, the development may still be CIL liable, where a new dwelling is created or where the new development would result in more than 100m2 of new build floorspace.  In such instances, a Form 5 notice should be submitted before development is commenced.  

Planning application fees

There are different fees depending on the type of application you are making.  Find out how much your planning application is using the Guide to Planning application fees.  You can also use the fees calculator and the volume calculator to help you.  Please note that planning application fees are due to increase on 17 January 2018.

How to pay

You can pay for your application in a number of ways.

  • By paying online via the Planning Portal when you apply online
  • By paying online (if you have already submitted your application). Please note that to make an online payment for planning fees you will need either your planning portal reference number or the planning application reference number.
  • By cheque, payable to Hertsmere Borough Council. Send it with your application to our main office.
  • By debit or credit card over the phone, once you have submitted your application. Telephone 020 8207 2277.
  • By asking a member of our Validation Team to contact you to obtain your card details. They will then complete the transaction for you using the online facility.

If you have a question about payment or application fees, contact our Validation Team on 020 8207 2277 or by email: admin.planning@hertsmere.gov.uk

Planning Applications - Keeping Your Personal Information Safe

Planning legislation (the Town and Country Planning Act 1990) requires Hertsmere Borough Council to make details of applicants and proposals for planning permission publicly available.  These details include some personal information, such as names and addresses.

You need to be aware that when you submit a planning application to us, the application, plans and any related documents or comments that you send to us are permanently kept as part of the public record.  We have a statutory duty to make them available for any member of the public to see (via our website www.hertsmere.gov.uk) and to have copies of.  This includes planning application documents and consultation responses received in paper format, which we scan and keep electronically.

Who processes my data?

The information that you provide with a planning application will be processed by Hertsmere Borough Council, which is the ‘data controller’ for the purposes of the Data Protection Act.

What is my data used for?

The information that you provide for a planning application, including personal data, will be used to deal with your planning application.

Who sees my data?

Planning legislation requires Hertsmere Borough Council to make details of applicants and proposals for planning permission available for public inspection.  They are available on the Hertsmere website.

The name of the owner of a property or land, plus the address of that property or land, must usually be publicly available.  Hertsmere Borough Council is required to publish any comments (with the name of the person making the comment) received on planning applications, and they may be reported to the Council’s Planning Committee in summary form.  All comments received are also available for inspection by the public, applicants and Councillors.

If you are making comments on a planning application, to reduce the chances of identity theft please remember to:

  • Include the minimum necessary personal information from correspondence – usually your name, address and, if you would like us to contact you in another way other than post, one form of other contact (telephone or email).
  • If you wish to send in comments by email, send them as an attachment to the email rather than in the email itself, so that your email address is not shown.
  • Hertsmere Borough Council will take into account unsigned comments on planning applications, but does require a name and a postal address.

Details such as signatures, personal telephone numbers and personal email addresses are redacted before being published on the internet.

Individuals have a number of rights under data protection law, including the right to request their information. You also have a right to make a complaint about our handling of your personal data to the Information Commissioner’s Office https://ico.org.uk/
