The energy your building cannot see.
Your meter shows a total. It does not show the printer left on all weekend, the monitor bank drawing power at midnight or the bottle fridge humming away in an empty room. We have partnered with measurable.energy to put that detail on the table, and to switch the waste off automatically.

Print was only part of it.
For years we have helped customers cut the energy their printing uses, mostly by moving them off laser and onto heat-free devices. That work pays off, but it only ever covered one plug in the building. Everything else stayed invisible. Partnering with measurable.energy lets us take the same approach to the rest of the room.
- Proven, cybersecure technology. measurable.energy build the sockets and the AI behind them, certified to Cyber Essentials Plus and BSI ISO 27001. We supply, install and support them for our customers, the same way we do with print hardware.
- It suits estates, not just single offices. One printer left on overnight is easy to miss. Across forty sites it stops being a rounding error.
- Nobody has to remember anything. The rules run themselves, so savings do not depend on staff changing habits or the last person out checking every desk.
"Sustainability is a core part of our business model here at Insight Systems. Our partnership with measurable.energy is a natural extension of that commitment. While we've helped organisations make significant energy savings through providing more sustainable print solutions, we recognise that printers are only one part of the workplace energy picture."David McCulloch, Managing Director & Co Founder, Insight Systems
Identify, control, eliminate.
measurable.energy break it into three stages. Each one runs on the same hardware, so there is no separate survey phase and no sensors to install around the building.
Identify
Every plugged-in device is recognised by its energy signature. Machine learning works out what it is, where it is and how it behaves, right down to the idle and standby patterns other systems never see.
Control
Schedules and rules power things down without anyone stepping in. Savings are tracked and verified as they happen, so the reporting is ready when you need it.
Eliminate
Live energy and carbon are tracked per appliance against National Grid intensity data. Unusual patterns get flagged, so faults and fire risks surface before they become incidents.
Two places we see it working hardest.
It suits any building with a lot of plugged-in equipment, but these are the two that overlap most with the customers we already look after.
Commercial offices
Hybrid workingDesks sit empty for half the week but the kit under them does not know that. measurable.energy report that up to 40% of electricity use in commercial buildings comes from plug load, much of it unmanaged.
- Included: A reported 20%+ cut in plug load energy and cost across an estate
- Included: Desk and room usage data without cameras or extra sensors
- Included: Evidence for carbon reporting at portfolio level
Schools and education
Budget pressureIT suites and classrooms run well past the last lesson. Every pound not spent on electricity is a pound that stays in the teaching budget, which is why this lands so well with trusts.
- Included: A reported 20%+ reduction in electricity spend across an estate
- Included: One standard applied across every site in a trust
- Included: An LED on each socket shows live status, which pupils can read
One school, on the record.
These are measurable.energy's published figures, with the head teacher on the record.
"In under two years the cost of the socket will be paid for. They're going to be saving me about £7,000 or £8,000 a year as a conservative estimate, which is amazing."
Figures and quote published by measurable.energy, January 2026. The 25% to 40% range they quote covers all three pilot schools, not St Peters alone. Read the full case study or browse the rest.
measurable.energy filmed Iain Gunn and his staff at St Peters a month after the sockets went in. The short version: the classroom computers and screens now switch off at 6pm and come back on at 7am, and nobody has to remember to do it.
The teachers call them the magic plugs, mostly because they never notice them. That is rather the point.
measurable.energy report that the Diocese is looking at extending the same setup to a further 35 schools, which is the kind of decision that only follows a pilot people are happy with.
