Professional Portal

Welcome to the Professional Portal; a hub of tools, services and guidance for those working in the planning and building industry.

Here you will find signposts to select areas of the Planning Portal that have been designed to help you plan and manage your project in an easy and accessible way. 

Use our calculators to determine whether an extension is within permitted development limits and calculate your application fee, access legislation and guidance; such as use classes and approved documents, buy plans and maps from one of our three providers, keep up to date with industry news and find contact details of your local council.

If you have a recommendation for information you would like to see on this page or to subscribe to our monthly architectural bulletin, please email us.
