Your site cabins are quietly eating away at your profit.
A heater and an air conditioner fighting each other in the same office. A drying room running all night for one wet coat. Sixty-four hours heating an empty compound, every weekend. None of it is anybody’s fault, and none of it is anybody’s job. That’s what AutoMate is for.
The Gaia guarantee
At least a 50% saving on the energy waste in the areas we control, or we credit the difference back.
Projects of six months or more. That’s the only condition. The guarantee, and what it costs

Measure it. Fix it. Scale it.
Measure it
DataMate measures the real site, free. Every circuit in the board, on your own cabins, until consumption settles, ending with the wastage report.
Fix it
AutoMate removes the waste. The same box, switched on, controlling the loads worth controlling. £25 per cabin or bay per week. Discounts available for upfront terms, ask.
Scale it
Roll the proven system across projects, accounts and cabin suppliers, so cabins arrive on site already fitted.
Not sure it applies to your compound? Check how your site compares first. It is a benchmark, not proof of what your site is doing; DataMate measures that. Take a look inside the demo portal if you would rather see the measurement on a real compound before anyone comes near yours.
One box, working constantly, not just when nobody’s there
One box per cabin, fitted at the distribution board. It measures every circuit all the time and controls the heaters, air conditioning, dehumidifiers, water boilers, lights and sockets, continuously, not only when the cabin is empty. Sometimes that means switching something off. More often it means running it later, in a different order, or for a shorter time. And we prove it in your own kWh.
Nobody is managing the energy in a welfare compound
Not because site teams don't care. Because the circuits are invisible, and there is nothing on site that knows whether a room is occupied.
Heaters run all night in empty rooms
The site office is occupied for part of the day and heated for all of it. Nobody is there to switch it off, and a thermostat has no idea whether anyone is in the room.
Heating and air conditioning fight each other
Two independent controls in one cabin, one calling for heat and one for cooling. Both run. Both appear on the bill, and neither shows up as a fault.
Drying rooms run all weekend, empty
A drying room draws more power than the site office next to it. It gets switched on and left. Nobody notices, because nobody can see the circuit.
These are the findings that come back from real boards, repeatedly. They are also why energy waste survives good intentions: none of it is visible from inside the cabin.
How it works, at the board
One control box per cabin, fitted at the distribution board. Four double-pole 25A contactors intercept the circuits worth switching. Everything else in the board gets a current transformer so it is measured, whether or not we touch it.
- Four 25A double-pole contactors
- Both poles of a contactor control identical appliances in the same cabin, never split across two rooms, even for the same type of load.
- Which loads get switched depends on the cabin
- In a standard cabin: the heater or the air conditioning, the water boiler, the sockets, the lights. In a drying room: the heaters, the dehumidifiers, the fans, the sockets. Where a cabin has both a heater and air conditioning they're separate circuits on separate contactors. Circuits routed through a contactor sit on a breaker of 25A or less. The full scheme, both cabin types.
- Critical circuits are never switched
- Wi-Fi and data comms, showers, life-safety circuits, and anything else you designate as critical are CT-monitored only.
- Every circuit is monitored, even where it isn't controlled
- CT1 to CT4 sit on the contactors. Additional CTs go on every other circuit in the board. Your project manager sees the whole board, not just the parts we switch.
- Only line conductors are intercepted
- Neutrals and earths are never switched and stay in the distribution board unchanged. Power runs bus bar → MCB → contactor → load.
- Installed by a qualified electrician
- Tested to BS 7671, with a New Installation Certificate handed over on completion.
- Then the rules do the work
- Timers, occupancy, and peak shaving. Not a thermostat, and not somebody remembering.
Your site manager sees every circuit in the portal. Ask AutoMate a question in plain English, or request a change and we'll handle it.
We supply a box. We don't supply cabins.
You keep your existing cabin supplier, always.
Our preferred route is the one that costs you least effort: we ship our units to your cabin supplier, and they fit them during cabin setup. The cabin then arrives on site already fitted. Nothing to arrange, no install to schedule around your programme.
That's what we call a Gaia Enabled cabin, their cabin, our box in it. Lead time to a supplier is 10 working days from receipt of purchase order.
You don't need your supplier involved to start, though. On your first sites we install free ourselves, and we already ship boxes to a major plant hire firm who fit them at manufacture.
Installation is included
At every stage, and never charged.
- Your first sites: we install free.
- More sites: still installed free as you add them.
- At scale: your cabin supplier fits them at manufacture; we attend to commission.
Always by a qualified electrician, tested to BS 7671, with a New Installation Certificate handed over on completion.
The guarantee, and what it costs
One guarantee, two limbs
We guarantee at least a 50% saving on the energy waste in the areas we control. And if our fees come to more than we've saved you across the project, we credit the difference, so you cannot end a project out of pocket.
Projects of six months or more. That's the only condition.
Assessed across the project and settled once at the end, not month by month. Savings are valued at your own electricity rate, agreed up front, and measured against your site's own benchmark.
Why we settle at the end
Savings peak in spring and autumn, not winter. Summer has little waste available to remove, and in winter the heating is genuinely needed. The same site read 37% across a summer (13 May to 31 July 2025) and 65% across a full year (13 May 2025 to 30 April 2026).
So an early report on a summer start will look thinner than the final position. Judging it month by month would penalise a project for the time of year it began.
We'd rather tell you that now than have you find it in month two.

The 57% is the whole period, including the diesel saved while the site ran on a generator. The £11,669 is on the grid basis only.
Electricity rates are supplied by each customer and range from 24p to 30p per kWh, so the rate is printed next to every £ figure. £ savings are not comparable between sites and are never averaged or totalled; compare on kWh and percentage.
