measurable.energy is a UK-based company helping businesses track, analyze, and reduce energy waste. The company’s smart devices, including intelligent plug sockets and fused spurs, automatically monitor electricity consumption and curb unnecessary usage. Founded in 2018 by Dan Williams and Josh Eadie, the company transforms everyday electricity use into insights that cut costs and reduce carbon emissions.

Dan Williams, co-founder and CEO, brings deep expertise in energy efficiency and environmental technology. With a PhD on the environmental and energy impact of Microsoft’s software services, he spent over a decade developing sustainability strategies for organisations including Google, Telstra, Heathrow Airport, and the BBC. His experience highlighted how even small, overlooked energy usage in offices and facilities could add up to significant environmental impact.

Tracking Hidden Energy Waste

Many businesses focus on large-scale efficiency projects while overlooking the smaller devices that silently drain electricity. Williams noticed that there was no simple way for organisations to identify these sources of waste. “Most companies don’t even realise how much energy is being used by plugged-in devices that aren’t actively in use,” he says. “Our goal was to make it visible and manageable without adding complexity to day-to-day operations.”

measurable.energy uses smart devices that monitor standby power and optimize usage automatically. The system gathers detailed data, giving businesses a clear picture of where energy is being wasted. “We wanted something that works quietly in the background, helping teams make real changes without having to change the way they work,” Williams adds.

The approach has shown measurable results. Clients using the devices have reported up to a 20% reduction in electricity usage and carbon emissions. These savings are particularly impactful for businesses operating multiple sites or large facilities, where small efficiencies multiplied across dozens of devices can lead to substantial environmental benefits.

Technology That Works

The technology itself is straightforward but sophisticated. Each smart plug or fused spur connects to a secure network and continuously monitors electricity flow. Machine learning algorithms analyze usage patterns and identify opportunities for reduction, automatically switching off devices that are unnecessarily drawing power.

“Many businesses struggle to find actionable energy insights in real time,” Williams explains. “We provide clarity on energy use and allow organisations to act immediately. Our technology doesn’t require energy experts on site, it just works.”

The devices also generate reports for sustainability teams, helping them demonstrate compliance with environmental targets and provide data for ESG reporting. This capability is especially valuable as companies face increasing scrutiny from regulators, investors, and customers to show measurable progress in carbon reduction.

Proven Impact

Since its launch, measurable.energy has helped a variety of organisations improve efficiency and sustainability. The University of Reading reduced electricity usage by 872 kWh in just two months with the smart devices. Wernick Group achieved a 23% reduction in carbon emissions within four months of deployment. These examples demonstrate that small, targeted interventions can create tangible impact when combined with data and automated monitoring.

Williams emphasizes that the impact goes beyond numbers on a report. “We are helping businesses make sustainability a natural part of daily operations,” he says. “It’s not about installing technology for technology’s sake; it’s about creating lasting behaviour change that benefits both the environment and the company’s bottom line.”

Scaling Sustainability

measurable.energy is expanding its reach to support more businesses across industries. Williams sees potential for the technology in offices, manufacturing sites, and retail spaces. “The underlying principle is the same everywhere — visibility enables action,” he notes. By scaling its devices and analytics, the company can help organisations of all sizes take control of energy use.

The company is also exploring ways to integrate its technology with existing building management systems, making energy reduction seamless and automated. Partnerships with sustainability consultancies and corporate clients ensure that the devices are used in contexts where they can have the most impact.

Simplifying Efficiency

For Dan Williams, the broader mission of measurable.energy extends beyond individual energy savings. He envisions a future where businesses of all sizes can actively reduce their environmental impact without complex planning or disruption. “We want energy efficiency to feel effortless,” he says. “Our clients shouldn’t need to hire specialists or run complex programmes to make real change.”

The company’s approach also addresses a wider challenge: many businesses want to demonstrate progress toward sustainability goals, but data and reporting can be fragmented or unreliable. measurable.energy consolidates the data, provides clarity, and shows measurable outcomes in real time. This combination of action and accountability is increasingly important in a world where stakeholders expect transparency in environmental impact.

Driving Change

Under Williams’ leadership, measurable.energy has combined technology, usability, and insight to make a meaningful difference. By focusing on often-overlooked energy waste and offering simple ways to act, the company allows organisations to reduce costs, meet sustainability targets, and demonstrate leadership in environmental responsibility.

Williams highlights that success is not measured solely by energy savings but by the broader contribution to climate goals. “Every watt we save is a step toward a cleaner, more sustainable future,” he says. “Our mission is to make energy efficiency both practical and impactful for every business, from small offices to large facilities.”

measurable.energy stands as an example of how technology can simplify sustainability and empower businesses to act decisively. By turning everyday energy consumption into data-driven opportunities for reduction, Dan Williams and his team are helping organisations cut emissions, save costs, and lead by example in the energy transition. The company’s approach proves that small, informed actions, when scaled across multiple sites and devices, can collectively create significant environmental benefits.
