- Founded in 2006, Best.Energy, specialises in helping multi-site businesses reduce their building’s energy usage through innovative energy management solutions;
- Headquartered in Bristol, the company achieves significant energy reductions for businesses across multiple sectors in over 40 countries;
- The £6.25m funding package will support specialist impact investor, Future Business Partnership’s (FBP) investment into the company in a majority buyout alongside management;
- The global energy efficient building market is set to grow at a compound annual growth rate (CAGR) of 11.3% from 2026-2034, driven by the need to reduce energy consumption, lower carbon emissions, and improve long-term operational efficiency of buildings[1].
London, 16 April, 2026: OakNorth, the digital bank for entrepreneurs, by entrepreneurs, has provided a £6.25m funding package to support Future Business Partnership’s investment into Bristol‑based energy efficiency specialist, Best.Energy.
Founded in 2006, Best.Energy is a UK-based energy efficiency specialist that helps multi-site organisations cut energy use, costs, and carbon through its proprietary IoT hardware, cloud software, and AI-enabled services. Its technology, including its “Eniscope” platform and “Air” range of sensors and controls, provides real-time, asset-level visibility of energy consumption, enabling businesses to identify and eliminate waste – typically delivering double-digit percentage savings on energy bills. The company has grown from a Cornish start-up into a global energy management player, with its technology deployed across thousands of sites in more than 70 countries and supporting blue-chip clients across sectors including restaurants, retail, leisure, manufacturing, and education.
The £6.25m funding package from OakNorth will support European specialist impact investor, Future Business Partnership’s (FBP) investment into the company in a majority buyout alongside management, as well as support Best.Energy’s future growth via a bespoke Revolving Credit Facility (RCF). The transaction will see the successful exit for leading independent provider of private equity and venture capital to SMEs, Percipient Capital.
Troy Wrigley, CEO of Best.Energy, said: “It’s remarkable to think that over 30% of the energy businesses pay for is wasted – they just don’t know which 30%. That’s why we invented our unique energy saving platform. It shows you exactly where the waste is and enables you to eliminate it. With the backing of FBP and the support of OakNorth, we’re well-positioned to accelerate our growth and help more organisations globally reduce energy costs and achieve their net zero ambitions.”
Tracey Huggett and Vish Srivastava, Managing Partners of FBP, commented on the transaction: “Best.Energy is exactly the sort of business in which FBP was built to invest in. Our peers across the PE industry are always focusing on cost efficiencies for their portfolio, in this macro environment more than ever, and Best.Energy can enable them to save money and save carbon, a win-win for business and for the planet. Having the support of OakNorth on this transaction and working with Stewart Haworth who brings deep expertise in supporting private equity-backed businesses, gives us additional confidence as we look to scale the company and maximise its impact.”
Stewart Haworth, Senior Director of Debt Finance at OakNorth, added: “We’re delighted to support FBP and the management team at Best.Energy on this transaction. Having worked extensively with private equity investors, we understand the importance of flexible, tailored financing solutions that can support both acquisition strategies and long-term value creation. The energy efficiency market is seeing significant and sustained demand, with strong double-digit growth projected over the coming years. This creates a compelling opportunity to back high-quality, scalable platforms like Best.Energy, which combine proven technology with immediate, tangible ROI for customers. We look forward to supporting the business through its next phase of growth.”
Best.Energy and Percipient Capital was advised by SRC Corporate Finance (Lead Advisory) and DMH Stallard (Legal). Future Business Partnership were advised by Alvarez and Marsal (Corporate Finance), Roedl and Partner (Accountancy and Financial Advice), Burness Paull (Legal), K&L Gates (Legal), Johnston Carmichael (Tax), Greenheart (Impact and Accountability), Cantec Energy (Technology), SiCol (Supply Chain Risk), Brown & Brown and Bridge Specialty (Insurance), Cyber DueDil (Cyber Risks), Hanuman Partners (Compliance) and Suntera (Compliance).
