The problem

Totals, not day against night.

About 70 UK sites, and reports that showed totals, not what each site used out of hours.

“I couldn’t see what we were using during the day, out of hours.”

Brendan Cornick, Portakabin
Portakabin’s offices in York

What the teams fixed

No new kit. A walk round with the numbers.

22 sites connected from January 2026. Each team saw its own energy, day and night.

Toilet heaters

Flat out, day and night. Now under control.

A storeroom

Heated to 26°C with the doors open. Sorted.

Drying rooms

Heated four hours early. Now 40 minutes.

Friday evenings

One named person switches off.

A modular building at dusk with every window lit

Next

Solar, gas and water, in the same view.

And a trial of automatic switch-off on one site.
