UK voluntary carbon market · solar

Your panels already work hard.
Now make them pay twice.

Every kilowatt-hour your solar generates avoids carbon — and that avoided carbon has a value. CarboniQ turns the clean power you already produce into verified carbon certificates, sells them to businesses offsetting their footprint, and pays the income back to you.

No change to your existing setup Independently verified credits No upfront cost

The simple version

You generate clean power. Someone, somewhere, needs to account for theirs.

Businesses that can't yet cut all of their emissions buy carbon credits to balance the books — each credit representing one tonne of CO₂. Your solar is creating exactly that kind of saving. We connect the two.

A second income from one roof

Feed-in and export tariffs pay you for electricity. Carbon income pays you for the emissions you avoid — a separate, additional revenue line from the same panels.

Verified, not vague

We work to recognised carbon standards and independent verification, so the credits you sell are credible and the income you earn stands up to scrutiny.

We do the heavy lifting

Metering, calculations, verification, finding buyers, getting you paid. You hand us the generation data; we handle the market.

*Illustrative only. Real income depends on your verified generation, the grid's carbon intensity, the standard your credits are certified under, and the market price when they're sold. Not a guarantee or an offer.

From sunlight to settled

Four steps, and most of them are ours.

We've built CarboniQ so you barely have to lift a finger after the first conversation. Here's the whole journey.

Read the detail

We measure your generation

A small meter or your existing monitoring records exactly how much clean power your system produces — the basis for every credit.

We convert it to carbon

Each unit of generation is translated into avoided CO₂ using recognised methodology, then independently verified into sellable credits.

We find the buyers

We sell your verified credits to organisations balancing their footprint on the voluntary carbon market — and handle the contracts.

You get paid

Income lands with you on a regular cycle. Track it through your dashboard; withdraw when you like.

Built for portfolios and single roofs alike

Whoever owns the panels, there's value on the roof.

Commercial installers

Offer carbon income as a selling point on every quote, and earn a recurring line from the base you've already built.

Housing associations

Turn rooftop solar across your stock into a verified income stream that can be reinvested in tenants and retrofit.

Private businesses

Make your sustainability investment pay back faster, with income and a credible, reportable carbon story.

Homeowners

A genuinely passive top-up on your panels — no new kit on the roof, no contract lock-in, no fuss.

Why now

The UK is putting its weight behind carbon markets.

In April 2025 the government set out plans to strengthen voluntary carbon and nature markets and raise their integrity — positioning the UK as a global hub for green finance. Markets like these are projected to be worth up to $250 billion by 2050.

That direction of travel matters. It means more demand for high-quality, verified credits — the kind your solar can supply — and a clearer rulebook for the businesses buying them.

Understand the market
  • One credit = one tonne of CO₂. A standard, tradable unit that the whole market understands.
  • Independent verification. Credits are checked by third parties so buyers can trust what they're paying for.
  • Retired once, counted once. When a credit is used it's retired, so the same saving can't be sold twice.
  • Honest claims. We follow UK guidance on green claims, so nothing we say on your behalf overstates the impact.
