There’s no obligation, and your home is surveyed before anything is agreed.


A typical home system can cover a large share of your annual electricity use, cutting bills from day one. Add a battery and you can store daytime power for the evening peak.
Panels also raise your home’s EPC rating, and you can earn money for the electricity you export through the Smart Export Guarantee.
- A typical 3-4kW system for a three-bedroom home costs a few thousand pounds, less than it did a few years ago
- Adding battery storage costs more up front but lets you use far more of what you generate
- VAT on domestic solar panels and batteries is currently 0%
- Most homes see their panels pay for themselves well within their 25-year lifespan


Panels must not stick out too far from the roof and there are extra rules for listed buildings and homes in conservation areas, so it’s worth checking with your local council if you think either applies.
Your installer will also register the system with your electricity network operator - you don’t need to do anything.

Choosing a solar panel installer is a major decision. Our checklist covers the essential steps, from verifying accreditation to comparing quotes and understanding warranties.
It depends on the size of your system, which way your roof faces and how much of the electricity you use at home. A typical three-bedroom house with a 3-4kW system can cover a large share of its annual electricity use, and adding a battery lets you use much more of what you generate rather than exporting it.
Usually not. Solar panels on houses are normally covered by permitted development rights, as long as they don't project too far from the roof. Listed buildings and homes in conservation areas have extra rules, so check with your local council if either applies to you.
A battery stores the electricity your panels make during the day so you can use it in the evening, when most homes use the most power. It costs more up front, but if you're out during the day it can make a big difference to how much of your own power you actually use.
Yes. Under the Smart Export Guarantee, licensed suppliers must offer a rate for the electricity you send back to the grid. Rates vary between suppliers, so it's worth comparing them once your system is installed.
Most panels are warrantied for 25 years and keep working well beyond that, losing only a small fraction of their output each year. Inverters typically need replacing once during that time, and batteries carry their own warranty of around 10 years.
A typical home installation takes one to two days once the survey and scaffolding are sorted. Your installer registers the system with your electricity network operator, so there's nothing you need to arrange yourself.
