measurable.energy, the UK tech company that designs and manufactures AI-powered plug sockets that reduce electricity costs and carbon emissions in offices by up to 50%, has secured a £4m Sterling tranche of new investment. The investment will accelerate the company’s rapid business growth in the UK and international markets ahead of its anticipated Series B fundraising in 2025.
The investment round has been co-led by Vertex Exploratory Fund, a fund under Vertex Holdings, alongside existing investor, Clean Growth Fund – the specialist UK clean tech venture capital firm. Vertex Holdings is a wholly-owned subsidiary of Temasek Holdings.
It is the Vertex Exploratory Fund’s first investment in the UK’s clean tech, and Vertex Exploratory Fund will help measurable.energy to expand the company’s presence overseas, in particular within South East Asia.
Other participants in the round include existing investors Bonheur ASA/Fred Olsen, The RO Group, Vectr7 and Roger Ferguson, a former economic adviser to President Barack Obama and a former Vice-Chair of the US Federal Reserve. Mr Ferguson, who sits on the Board of Alphabet Inc., has been a part of measurable.energy’s journey as an investor since 2023 and is supporting the company’s expansion within the US.
measurable.energy offers customers a smart plug socket equipped with proprietary hardware and AI-driven software to tackle the significant energy drain from small devices — those appliances that remain plugged in and running even when they’re not in use. In offices, plug power accounts for up to 40% of total electricity usage and around half of it gets wasted. measurable.energy’s energy efficiency technology eliminates this waste of electricity, helping companies to reduce their energy costs and carbon emissions by up to 50%.
The company’s main business lies within the construction and commercial real estate sectors, with growing demand from the public sector, hospitality, university campuses and NHS hospitals.
Clean Growth Fund made its first investment in measurable.energy in January 2023, alongside The RO Group, Vectr7 Investment Partners LLP, and MMC Ventures Limited. Since then, the company’s revenues have grown more than 10x, secured a series of major commercial agreements including Balfour Beatty Vinci, Morgan Sindall and PKF Francis Clark and strengthened its senior management team: Karen Bach was appointed Chair in June last year, with Dave Wardell joining in October last year as Chief Commercial Officer. Dan Williams, co-founder of measurable.energy, has been CEO since 2018.
Jonathan Tudor, Investment Partner at Clean Growth Fund said:
“Clean Growth Fund has been delighted with measurable.energy’s growth over the past 18 months. With the support of CGF, Vertex and their other investors, the company is in a strong position to win business overseas, in particular within SE Asia, the USA and Europe.”
“measurable.energy isn’t just another player in the energy efficiency space. The combination of its advanced hardware and AI software represents a significant leap forward in energy management technology. In today’s tech-driven world, where every watt of energy saved can contribute to a more sustainable future, measurable.energy is leading the charge with its technology.”
Shang-Wei Chow, Managing Director, Investment of Vertex Exploratory Fund who will be joining the Board as Director said:
“The Vertex Exploratory Fund actively seeks out disruptive frontier technologies with climate as one of the core themes in our investment strategy. measurable.energy stood out as one of the most promising startups in the UK in the climate space, offering a low-touch, intuitive, and compliance-ready solution that effectively reduces power waste. The company is at the forefront of providing the tools necessary to drive positive change and the Vertex Exploratory Fund is proud to partner with them on this journey.”
Dan Williams, co-founder and CEO of measurable.energy said:
"We are grateful for the continued support of our current investors and are excited to welcome Vertex as a new partner during this pivotal time in our growth journey. This investment reflects the confidence in our proven AI-powered technology, which has already made a real impact for businesses across the UK. As we look to the future, we are excited to build on this momentum and pursue our ambitious goals to enhance energy efficiency on a global scale. This is an exciting time for our team, and we’re ready to lead the change in energy management.”

Notes to Editors
What is measurable.energy’s smart socket technology?
- Smart Sockets: measurable.energy’s smart sockets are more than just power sockets. They are equipped with sensors and communication technology that automatically identify and monitor the usage patterns of connected devices.
- AI-Powered Detection: The system uses machine learning to analyse when plug power devices are idle or not actively in use. This intelligent analysis helps to determine patterns of usage and when power consumption can be safely turned off.
- Automatic Device-Level Control: Based on the AI’s findings, the smart socket automatically turns off power to devices that are not in use (and back on when they are). This eliminates unnecessary energy consumption without requiring any manual intervention from users.
- Energy and Cost Savings: By stopping the power flow to inactive devices, measurable.energy’s solution helps users save on their energy bills, reduce overall power consumption, and lower carbon emissions. The return on investment for socket customers is as short as 21 days.
