Who we are
about granyt
For years, corporates have had access to funded solar.
Our mission is to give UK SMEs the same access, and level the playing field.
Granyt stands out by combining innovative, tech-enabled financing models with expert guidance, tailored specifically for SMEs. Our end-to-end service simplifies the switch to solar, ensuring a seamless experience from initial consultation to ongoing maintenance. We recognise that navigating the solar energy landscape can be complex, especially for SMEs. That’s why Granyt prioritises transparency and education, ensuring our clients are well-informed at every step of their renewable energy journey
granyt's story
Granyt was founded by two friends — Caroline Haynes and Bernard Yu — who’d spent years advising on major infrastructure and financing billion-pound projects.
But it became clear that the businesses who needed help most — small and mid-sized manufacturers, logistics firms, bakers, brewers — were locked out. Climate finance was being routed to the giants, while SMEs faced rising energy costs and no affordable way to go green.
So we started Granyt with a simple mission:
To give UK SMEs the same funded energy transition that big corporates get — without the complexity or the cost.
But as we worked with more businesses, we saw something deeper: the ‘imperfect information’ paradox.
Commercial solar is a new, technical, fast-moving space — and most of the time, the seller knows more than the buyer. That creates risk, confusion, and bad decisions.
So we expanded Granyt. We don’t just provide funding — we guide SMEs through the whole journey: from early savings estimates to installation, monitoring, and long-term support. We’re not just a lender. We’re your solar partner.
Today, we’re a growing team of commercial solar experts, product builders, and financiers, working to unlock the energy transition for the businesses that keep the UK running.
