Solar Panel Installation Permissions in the UK: Planning, Conservation Areas, and Grid Notification

Introduction: Navigating Solar Panel Installation Permissions in the UK

Understanding the permissions required for installing solar panels in the UK, particularly in terms of planning permissions, is essential for homeowners. Ensuring compliance with local regulations ensures there will be no nasty surprises around the corner.

Permitted Developments for Solar Panels

General Guidelines for Domestic Solar Installations

Typically, solar PV installations for domestic properties fall under permitted development, provided they meet specific criteria:

Conservation areas and listed buildings need to apply for planning permission.

• The property is not listed or within the curtilage of a listed building.

• The property is not in a conservation area visible from a public highway.

• The solar PV system does not protrude above the highest part of the roof.

• The system does not extend more than 0.2m from the roof slope.

Searching for Current Legislation

We at solarandbatterycompany.com always recommend checking current government legislation through search engines to ensure your planned installation complies with the latest standards.

Misconceptions About Solar Installation in Conservation Areas

Many homeowners assume that living in a conservation area automatically disqualifies their property from solar PV installation. However, if the solar panels are not visible from a public highway, the installation still qualifies as permitted development. Consulting with your council, ideally with guidance from your installer, is crucial to navigate this area accurately.

Seeking Planning Permission When Required

When to Consider Planning Permission

If your property falls under restricted scenarios, obtaining planning permission from your local council is necessary. This process can extend the installation time by up to six months and may incur additional costs for required designs and drawings.

Recent Developments and Governmental Discussions

Discussions in late 2023 indicated potential government moves towards relaxing permitted development regulations for solar installations. This could include more flexibility for listed buildings and greater autonomy for local councils in determining development parameters.

Notifying the Grid: Essential Steps for Solar Installation

Your solar installer will apply for the relevant grid permissions for you.

Notification Requirements Based on System Size

The grid must be notified of any installed system:

For systems below 3.64kWp per phase, a retrospective G98 notice can be issued by your installer.

For systems exceeding 3.64kWp per phase, a G99 application is necessary.

This notification is typically a procedural step and, depending on the system's specifics, approval is generally granted within 3-4 months by your DNO (Distribution Network Operator). More recently the grid has introduced a fast track option, where they will review the G99 application within 21 days.
