How Smart Plug Sockets Are Cutting Commercial Energy Waste by Up to 50%

Walk through most commercial buildings after hours and you’ll find a quiet drain on the electricity bill: printers on standby, monitors left charging, kitchen equipment idling overnight. None of it looks like much on its own. Add it up across a whole building, though, and it is.

Our data, from sites we manage across the UK, shows that up to 50% of the electricity running through standard plug sockets in a typical commercial building is wasted on equipment nobody’s using.

The fix doesn’t need a building refit. AI-powered smart plug sockets, delivered through our partner measurable.energy, work out which circuits are wasting power, measure it in real time, and automatically cut supply to idle equipment — without anyone having to remember to switch anything off.

In practice, that’s worth somewhere between £493 and £2,530 per site per year, with most installations paying for themselves in 6 to 23 months.

It’s a small, unglamorous change. It’s exactly the kind of saving we look for first, before any conversation about generating your own power or switching contracts. The cheapest kWh is still the one you don’t use.
