When you need planning permission

Find out if and when you need planning permission, including advice on net zero and sustainable building.

You will most likely need planning permission when you build something new or make a major change to your building, for example building an extension or change the use of your building. There are some exceptions.

Check 'in this section' on this page for more information on if you need planning permission and what to do.

Climate action planning guidance

The Climate Action Supplementary Planning Document explains how to make buildings more energy efficient, reduce carbon emissions, use sustainable design standards and covers measures to mitigate climate change. We've created templates and checklists to guide applicants on Sustainable Design and Construction Statement requirements for different types and scale of minor development proposals.

The Islington Permitted Development Guide for Net Zero Works (PDF) explains the planning rules for making changes to homes and buildings to improve energy efficiency and save energy. It explains when you can make changes without planning permission, such as replacing windows or installing solar panels. These are called 'permitted development rights' and come from national legislation. The guide explains how the legislation applies in Islington.

The Retrofit Handbook helps households use less energy, improve heat retention, and adapt to the impacts of climate change. It covers planning requirements, DIY measures, estimated costs, how these measures apply to common types of home in the borough.

Windows in listed buildings and conservation areas

If your property is a listed building or in a conservation area, and you would like to repair, upgrade or replace your windows, then you are likely to need planning permission and / or listed building consent to undertake the works.

This guidance will help residents to find the best option and make a successful application for their windows. This is to align with the council's target of being a Net Zero Carbon borough by 2030.
