Planning permission for solar panels: Everything you need to know
A really common question we get asked by potential customers is: “Do I need planning permission for solar panels?” The good news is, in most cases, you don’t need planning permission for solar panels. But there are a few things worth knowing before you take the next step which we’ll look at in this article.
+ Most solar panel installations are “Permitted Development”
Across the UK, most standard domestic solar panel installations fall under something called permitted development rights. This means you don’t have to apply for formal planning permission with the council, as long as your system meets certain conditions.
Here’s what that usually means:
- The panels shouldn’t stick out more than 200mm from the roof surface.
- They should be installed in a way that minimises their visual impact.
- They shouldn’t be placed higher than the highest point of the roof (excluding chimneys).
If you’re adding panels to a flat roof, things can get a little more complicated – some flat-roof systems do require planning, especially if the panels are raised up at an angle on a frame. That’s something we can advise on during a survey.
+ Listed buildings and conservation areas
If you live in a listed building, or your property is within a conservation area (parts of Christchurch, old town Poole or old town Weymouth, for example), then the rules are tighter. You may need to apply for planning permission or listed building consent.
But don’t worry – this doesn’t mean solar panels are off the table. We’ve helped homeowners in these areas find creative solutions that meet regulations. For example, we worked with a customer near Bournemouth who had a period property. Working with the council, we designed a discreet, all-black panel layout that got approved and now powers their home beautifully.
+ Commercial properties and agricultural land
If you’re a business owner in Dorset, the rules depend on the size and placement of your solar installation. For larger systems or installations, you’ll usually need planning permission.
That said, smaller systems on commercial rooftops often qualify as permitted development too. We’ll help you assess what applies and, if needed, guide you through the planning process.
We know the word planning can sound daunting – but that’s where we come in. At Cooper & Cooper Solar, we’ve been installing solar panels for over 15 years and have dealt with our fair share of properties requiring planning permission. We’ll help check all the details for you, give honest advice, and handle the paperwork if permission is needed.
