Measurable Energy

measurable.energy designs and manufactures intelligent power outlets, fused spurs and accompanying software that monitor and control electricity used by plug-in appliances (plug load) in commercial buildings. Each device recognises connected equipment from its energy signature using machine-learning models, measures consumption at the appliance level, and automatically switches off idle, standby or wasteful loads according to learned usage patterns, schedules and rules, switching them back on when needed. The company states that plug load can account for up to 40% of office electricity use, roughly half of which is wasted, and positions its outlets as a lower-cost alternative to traditional building management systems.

Beyond energy reduction, the platform provides dashboards and reporting covering carbon output calculated with National Grid intensity data, anomaly detection intended to flag faulty appliances and overloaded circuits as a fire-risk control, space and asset utilisation insight derived from appliance activity, and occupant engagement features such as LED cues at the socket. The company reports integration with existing building management systems and IoT devices, and holds IASME Cyber Essentials Plus, IASME IoT Cyber Assurance Level 2 and BSI ISO 27001:2022 certifications.

Application areas cited by the company include construction sites and site compounds, commercial offices, retail, hospitality and educational settings. Its main business is in construction and commercial real estate, with additional demand from the public sector, hospitality, university campuses and NHS hospitals.

Founding story

Dan Williams and Josh Eadie began developing prototypes in March 2018 and founded measurable.energy in June 2018 to give businesses an accurate way to identify, measure and reduce small power waste. Both hold engineering doctorates; Williams worked with Microsoft software services during his doctorate and has built sustainability and energy strategies for organisations including Google, Telstra, Heathrow Airport and the BBC, while Eadie specialised in machine learning theory and robotics in partnership with Thales.

Business model

Hardware-plus-software: customers buy or deploy smart sockets and fused spurs and use the associated control centre, dashboards and reporting. The company references a subscription with a stated 2.4x return, and claims payback within a maximum of three years, with socket return on investment described in one account as short as 21 days.

Sales of intelligent power outlets and fused spurs combined with a software subscription for monitoring, automation and reporting.

Traction

The company reports 21.4 billion data points captured across 385.4 million hours of appliance-level monitoring and £47,500 of annual savings in its own offices through occupancy insights. Revenues grew more than tenfold between the January 2023 investment and October 2024, alongside commercial agreements with Balfour Beatty Vinci, Morgan Sindall and PKF Francis Clark. Customer cases cite a 40% energy cost reduction at St Peters Primary School and a 50% energy bill reduction in six months at Penningtons Manches Cooper.

Latest developments

In October 2024 the company announced a £4 million Series A follow-on co-led by Vertex Exploratory Fund and Clean Growth Fund, intended to fund UK and international growth ahead of a Series B anticipated in 2025, with Shang-Wei Chow of Vertex joining the board. Leadership has been expanded with Karen Bach as Chair (June 2023), Dave Wardell as Chief Commercial Officer (October 2023), plus a CFO and CMO. The company has also announced a partnership with Insight Systems on appliance-level energy waste across UK workplaces and published an article on further backing for its next phase.
