Salary benchmarks
Our take
Sunsave, founded in 2022, is on a mission to make the power of solar accessible to every household in the UK. They're the first (and as of 2025 the only) company in the UK to offer an FCA-authorised solar subscription service - a model that's been very successful in places like Germany and the US.
70% of people in the UK are interested in solar, and Sunsave's model removes the biggest barrier to adoption - the ~£10k typical upfront cost and long payback period - so customers can save on their energy bills from day one. They offer an all-in-one subscription that includes finance, installation, monitoring and maintenance, really helping customers get the most out of their systems
Already, the company has attracted the attention of blue-chip VC funds such as Norrsken, IPGL, the UK Department of Energy, and household name entrepreneurs, including Michael Spencer and Stuart Rose. Alongside this, they raised a £13M Series A in July 2025, alongside a £100M debt facility to scale their subscription model.
They plan to also expand into complementary products like EV chargers and heat pumps, alongside tariff optimisation and energy insight software. The eventual aim is to build the company's first decentralised home energy platform and revolutionise households' relationship with energy.

Company values
- We're changing how people power their lives: We know that only doing what’s familiar or easy isn’t going to get us there, so we’re unashamedly ambitious and set audacious goals. We’re excited by the hard problems that come with accomplishing something difficult, and we do whatever it takes to get closer to achieving our mission
- We start with the customer: We’re here to help real people, so their voices are at the centre of everything we do. We know that we can’t create a hugely successful business without building things that people really love. So everything we do starts with us asking: ‘What’s best for the customer?’
- We make it happen: We act with urgency, constantly prioritising to make sure we channel our energy into what matters most. We believe every problem has a solution, and we take ownership to figure it out. When we don’t have perfect information it doesn’t slow us down: we act, learn and adapt
- We drive each other to be exceptional: We’re one team, made stronger by supporting each other, sharing openly, and holding ourselves and each other to the highest standards. We prize honest constructive feedback, and we value fresh perspectives and respectful differences of opinion. We win, lose and learn together, and don’t let silos or egos get in the way
