Questions
Costs & savings FAQs
How much do solar panels cost?
It depends on your roof, your electricity use and whether you add a battery. As a guide, our solar-and-battery packages start from £3,950 for a typical two-bedroom home, £4,950 for three bedrooms and £7,250 for four bedrooms, supplied and fitted. Use our calculator for a quick estimate, then we'll give you a fixed written quote.
What will solar actually save me?
Savings depend on how much you generate, how much of it you use yourself, your tariff and whether you have a battery. We work it out from your real bills rather than guessing, and our calculator gives you an indicative figure in under a minute.
Is there VAT on solar panels and batteries?
Solar panels and battery storage installed in homes in Great Britain currently benefit from 0% VAT. This relief is due to run until 31 March 2027. Our quotes always make the VAT position clear.
Can I get paid for the electricity I export?
Yes. Under the Smart Export Guarantee (SEG), larger energy suppliers must offer a tariff that pays you for electricity you send to the grid. Rates vary by supplier, and you'll normally need an MCS-certified installation to qualify.
