UK voluntary carbon market · solar
Every unit of clean energy your solar, battery or heat pump produces or saves avoids carbon — and that carbon has a value. Carbonode turns it into verified certificates, sells them to businesses offsetting their footprint, and pays the income back to you.
The simple version
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.
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.
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.
Metering, calculations, verification, finding buyers, getting you paid. You hand us the generation data; we handle the market.
Earnings estimator
Pick who you are, tell us roughly what you've got, and we'll show an illustrative figure. Adjust anything — the numbers update as you go.
Rough figures are fine — you can refine them with us later.
*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
We've built Carbonode so you barely have to lift a finger after the first conversation. Here's the whole journey.
Read the detail →A small meter or your existing monitoring records exactly how much clean power your system produces or saves — the basis for every credit.
Each unit is translated into avoided CO₂ using recognised methodology, then independently verified into sellable credits.
We sell your verified credits to organisations balancing their footprint on the voluntary carbon market — and handle the contracts.
Income lands with you on a regular cycle. Track it through your dashboard; withdraw when you like.
Built for portfolios and single roofs alike
Offer carbon income as a selling point on every quote, and earn a recurring line from the base you've already built.
Turn low-carbon kit across your stock into a verified income stream that can be reinvested in tenants and retrofit.
Make your sustainability investment pay back faster, with income and a credible, reportable carbon story.
A genuinely passive top-up on your low-carbon kit — no new hardware, no contract lock-in, no fuss.
Why now
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 £200 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.
