Checking your roof, wall or garden
What your wall is made of decides whether the planning rules cover a panel at all. We check that first, before anyone gives you a price.

Send us your postcode and where you'd like the panel. We'll check it against the planning rules, tell you what it would generate at your address, and arrange a local electrician if you need a socket fitted.

Your name, postcode and email, plus the roof, wall or garden you have in mind. We reply by email with what the rules allow there and what it would make in a year.

That is what one 800 watt device makes on an unshaded south facing roof pitch near Exeter. Only the South East does better. Treat it as the most you could expect. What you save depends on how much electricity you are using while the panel is generating.

You can plug the panel in yourself. If you need a weatherproof socket outside, we get a local electrician to quote for that work.

The operator needs your name, your email and the address the panel went in at. We fill the form in with you.

The planning rules for solar equipment were rewritten on 27 August 2026. For houses and for blocks of flats, they no longer cover a plug-in panel fixed to a wooden wall, to a balcony, or to timber cladding. A twelve month transitional period runs to 27 August 2027, and until then you can follow either the old rules or the new ones.
A house that falls outside the rules can only get there through a planning application. The government expects that to cost a lot next to the price of the kit. We check the surface first so that you know where you stand before you spend anything.

All four figures below are for the same address near Exeter and the same 800 watt device. Where you put the panel makes more difference than which part of the country you live in.
PVGIS, four mountings, 0.8 kWp with 14 per cent system losses, unshaded, at one point near Exeter. Queried 13 September 2026. A region is not a point, and a coastal site is not an inland one.


South West England is one distribution licence area, and the operator for it is National Grid Electricity Distribution (South West) plc. Our map is a working one, so confirm yours on the operator's own postcode checker before you send anything. You can also ring 105. The call is free from anywhere in England, Scotland and Wales, and it puts you through to the company that runs the wires in your street.

Usually not, but it depends on your house. A plug-in panel relies on the permitted development right for small scale solar, and that right has limits on how far the panel sticks out, on conservation areas, on listed buildings and now on wooden surfaces. If your house meets the conditions, there is no application. If it does not, there is one. We tell you which applies to you before you spend anything.
One per household. The product specification allows one device per final ring circuit and then defers to the network rules, and Engineering Recommendation G98 Issue 2 Amendment 1 sets the limit at one per home.
No. Storage was left out of the interim product specification, both as a battery on its own and as a device with storage built in. A kit sold to you with a battery attached is outside what was approved in August.
We do not publish a price, because it depends on the kit you choose and on the socket work at your house. We would rather look at your house and give you a real figure.

Tell us the postcode and what the panel would be fixed to. We will write back with what the rules allow there and what it would make in a year. If it will not work at your house, we will tell you that.
