Customer testimonials

"The smart sockets from measurable.energy support our Net Zero goal by reducing energy and carbon usage. They let us monitor consumption down to individual devices and report accurately — all with minimal input from our team."
Mark McGonigle
Energy Manager at Dalkia
"measurable.energy made it easy to cut energy and carbon costs across projects. Their sockets are simple to install, look smart, and help teams reduce usage with built-in carbon LEDs. After strong results at Woodburn, we plan to roll them out more widely."
Neil Morris
Environmental Advisor, Kier
"At Silbury House, integrating measurable.energy’s smart sockets into our refurbishment cut plug power use and carbon emissions. This often-overlooked area is now central to our sustainability strategy, supporting our net zero goals with real-time data and automation."
