Making a planning application

If you haven't already, you'll need to register for a planning application account before being able to make a planning application.

If you have already registered, you can begin your application.

A planning application cannot be progressed until all the necessary supporting information and the appropriate fee is received by us. If we do not receive all the relevant information and the correct fee, your application will be made invalid and we will write to you.

Applying online

Registering on the Planning Portal is easy and you can complete your application form, upload supporting documents and pay fees via this service.

The simplest way to submit a planning application is online via the National Planning Portal where you can also:

  • work on your application in draft before submitting it to us;
  • receive immediate delivery and acknowledgement;
  • make savings on postage and printing costs;
  • find an online help function when completing applications; and
  • have an online record of your completed applications.

The Planning Portal

As well as being able to make planning applications, the Planning Portal provides information, guidance and answers to common questions.

You can email the Planning Portal directly by using,

Site Location Plans

An Ordnance Survey (OS) site location plan must be submitted with all applications.

Copies of OS plans are currently available from:

Hertfordshire Archives and Local Studies and Welwyn Garden City Library Information Service can print the latest OS maps which can be used in your planning application and you can also buy historic maps for a particular site.

Hertfordshire County Council can provide Ordnance Survey maps for planning applications.


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 scale. The requirements for what must be submitted are set out in the National Planning Practice Guidance Notes.
