Maximising your returns
Good news: most solar panel installations in the UK don't require planning permission. They're covered under 'permitted development rights.'
When you don't need permission
Permitted development applies if:
Panels don't protrude more than 200mm from the roof surface
They're not higher than the highest part of the roof
You're not in a conservation area or listed building
When you might need permission
Listed buildings, conservation areas, and ground-mounted systems over a certain size may require planning approval.

Pro tip
Bigger isn't always better. A well-sized system matched to your usage patterns will often outperform an oversized installation.
