We measure.
Not model.
Not estimate.
Most energy consultancy tells you what a building should be doing based on assumptions. We connect to your distribution boards and record what it is actually doing — every thirty seconds, across every circuit that matters, for 72 continuous hours. The difference between those two things is where your money goes.
Three approaches.
One fundamental difference.
There are broadly three ways a hotel group can assess its energy performance. Each has genuine value. But only one starts with what's actually happening inside your building.
These approaches are not competing alternatives — they serve different purposes. Bill analysis tells you what you spend. Modelling tells you what you could spend after major investment. Measured load analysis tells you what you are wasting right now, and exactly where it is going.
Two stories.
Both true. Both invisible
without measurement.
During a survey of guest room electrical equipment, our assessor was in a room recording equipment ratings when a dishwasher completed its cycle. He opened it.
Inside: a single fork and a single glass.
He asked one of the housekeeping team who had run it. The answer: all of them did it. Sometimes just a cup. Sometimes a plate. A full dishwasher cycle, run as routine, regardless of what was inside.
270 rooms. 270 dishwashers. Running full cycles for single items of cutlery, every day, across every floor.
At roughly 1.4kW per cycle, one unnecessary cycle per room per day represents approximately £15,000–£20,000 in avoidable annual electricity cost. The fix: a conversation with housekeeping management and a simple protocol change. Capital cost zero.
No bill analysis would find this. No building model would predict it. It only exists if someone is in the room, paying attention, and curious enough to open the door.
Boiler House — Continuous Load
Bedroom Block — Demand Led
Both profiles are from the same hotel, measured simultaneously. The bedroom block responds to demand — load rises and falls with occupancy. The boiler house does not. It runs at near-constant draw regardless of whether the hotel is full, half-empty, or in the middle of the night. That flat line is money. Measured, not modelled.
The incoming supply data showed total site consumption behaving broadly as expected — rising during the day, falling overnight. Nothing in the billing data suggested a problem.
Distribution board level monitoring told a different story. The boiler house was drawing near-constant electrical load at 3am as it was at 2pm on a busy afternoon. VSDs had been fitted — the correct equipment was in place — but the settings were wrong, or had been bypassed. The plant was running continuously at full output regardless of whether the heating and hot water system had any demand to meet.
Boiler house electrical consumption: approximately £95,000 per annum.
Projected consumption with correctly configured controls: approximately £81,500.
Identifiable annual saving: £13,000–£15,000.
Cost to implement — a controls engineer to review and reset existing equipment: £4,000–£5,000.
Payback period: 3–4 months.
This finding was invisible to the incoming supply meter. It required board-level measurement to isolate, and engineering experience to interpret. The equipment to fix it already existed on site. It simply needed someone to find the problem first.
"In excess of 50% of the hotel's energy consumption is associated with plant systems operating continuously rather than in response to demand." — Measured finding, large operational hotel
Every circuit
that matters.
We connect logging equipment to the distribution boards that tell the real story — not just the incoming supply, but the individual circuits serving plant rooms, lighting, guest floors and back-of-house areas.
Actual energy consumption at 30-second intervals across each monitored circuit. The number that determines your bill.
How consumption changes — or doesn't — over 72 hours including overnight and weekend periods. The flat line is the finding.
The efficiency with which electrical power is being converted to useful work. Poor power factor means you're paying for energy that does nothing.
Supply voltage levels across the monitoring period. Confirms whether voltage optimisation equipment is performing as expected.
The maximum and minimum demand within each period. The gap between them — and the shape of the minimum — reveals whether systems are responding to demand or running regardless.
Data tells you where to look. On-site observation tells you what's actually there — the equipment ratings, the control settings, the operational practices that no meter can record.
Simple to commission.
Rigorous in execution.
The survey is non-intrusive. No modification to existing systems. No disruption to operations. Equipment is powered from local socket outlets and can be installed during normal working hours.
Initial conversation
We discuss the property — its size, age, plant configuration, any known issues — to identify which distribution boards will yield the most useful data. This is a technical conversation, not a sales process.
Equipment installation
Portable logging equipment is connected to the main incoming supply and selected distribution boards. Non-intrusive, non-disruptive. Typically completed in a single morning.
72-hour continuous monitoring
Data is recorded at 30-second intervals across the full monitoring period — covering operational hours, overnight, and where possible across a weekend. This captures the complete pattern of how the building uses electricity.
On-site observation
While equipment is installed, a detailed walkthrough identifies what's operating, how it's controlled, and what the physical condition of plant and lighting actually is. The data points to where to look. The walkthrough finds what's there.
Analysis and report
Load profiles are analysed against on-site observations. Every finding is grounded in measured data. Savings estimates are derived from the actual load, the actual tariff, and engineering physics — not benchmarks or assumptions. Recommendations are ranked by payback period with realistic implementation costs.
The first survey
is free.
We offer one complimentary measured electrical survey per portfolio — because we are confident the data will speak for itself. No obligation, no assumptions, no generic recommendations. Just 72 hours of measurement and an honest report of what we find.
