Planning permission for renewable energy sources
We declared a climate emergency in 2019. Encouraging greener buildings is a top priority in our climate change strategy. We encourage installing renewable energy and heating systems. Also, retrofitting homes and business premises in Southwark.
You can usually install renewable energy and heating systems sources such as photovoltaic (PV) panels, air or ground source heat pumps without needing planning permission. This applies if the system meets certain conditions, including the size and location of the system, and heritage rules.
If you're unsure if your proposal needs planning permission, use our checker service.
If you want to be certain that your project does not need planning permission, you can then apply for a lawful development certificate (LDC).
Pre-application service
If your proposal needs planning permission, use our free pre-application service for renewable energy, heat and retrofit projects.

Boiler upgrade scheme
Through the boiler upgrade scheme, you could get a grant to cover part of the cost of replacing fossil fuel heating systems with a heat pump or biomass boiler.
Adding solar panels to your property
You do not usually need planning permission to install solar panels on your home. The panels should be fitted as close to the roof as possible, and must not be higher than the pitch of the roof. You can apply for a lawful development certificate to make sure your panels are permitted development.
If you want to install solar panels and live in a conservation area or a listed building, you will need to apply for planning permission.
When installing solar panels on your property, consider:
- installing panels on south, east or west-facing roofs (don't fit them on a north-facing roof as it gets too little sunlight)
- if anything is blocking the light, for example, a large tree or a nearby building (this could limit the amount of energy generated by the panels)
- installing only if your roof pitch angle is between 30 and 40 degrees (if you want to install panels to a flat roof, you may need planning permission)
