How Affordable Is Solar Energy in the UK in 2025? (Spoiler: Very Affordable)

There was a time when installing solar panels meant emptying your savings account. But today, thanks to technological leaps and increased competition, solar is more affordable than ever — and smarter too.

The average cost of a domestic solar panel system in the UK now ranges from £5,000 to £8,000 — but the real story is how quickly that investment pays for itself. Between government-backed incentives, energy bill savings, and the ability to sell excess energy back to the grid through schemes like the Smart Export Guarantee (SEG), many homeowners are seeing payback periods of as little as 5 to 7 years.

Plus, One Plus Power offers flexible financing options that make solar accessible for virtually every budget. Whether it’s low-interest loans or pay-as-you-save plans, Managing Director Reece Driscoll is determined to ensure cost is never a barrier to going green.

"Solar is no longer reserved for the few," says Driscoll. "Our mission at One Plus Power is to make renewable energy a practical, affordable choice for every UK household."

And the savings? Substantial. Households typically save up to 70% on electricity bills after installing solar panels. With energy prices climbing year after year, these savings add up quickly, turning solar into one of the wisest financial decisions you can make today.

Switching to solar isn’t just affordable — it's financially empowering.
