You won't need planning permission unless you want to install a very large system or a system on a listed building. For most UK homeowners, solar panels fall under 'permitted development rights', making the installation process straightforward.
Permitted Development Rights
What Are They?
Permitted development rights allow certain building works and changes to be carried out without needing to apply for planning permission. Solar panels have been included in these rights since 2008, significantly simplifying the installation process.Standard Requirements
