Energy monitoring and efficiency
services for UK industry

Five services. One method underneath all of them. We start with measurement, because you cannot make a business case out of a hunch.

Every one of these services is chosen and sized on the basis of what your own data says. Nothing on this page is sold as a package. Some sites need three of these. Most start with one.

Service 1 of 5

Energy monitoring: the great unifier

Every meter, machine and legacy system on one platform — including the equipment that speaks a different protocol to everything else.

The problem

Your site has meters from three different eras, a BMS that covers part of the building, machinery that reports in a protocol nothing else understands, and a monthly supplier bill that tells you what you spent but nothing about where it went. Asking which line costs the most to run turns into a week of manual work.

Why it matters

Without submetering you are managing energy at the level of the whole site, which means you can only ever negotiate on price. Every genuine saving we have found was invisible at site level and obvious at machine level. You are not short of savings. You are short of resolution.

What we do

We bring every meter, machine and legacy system onto one platform — including the awkward equipment. Long-range wireless networks such as LoRaWAN mean sensors can go where cabling cannot, and we use as much of what is already installed as possible rather than ripping it out.

What is included
✓Site survey and metering strategy
✓Submetering at machine, line or area level
✓Integration of existing meters, BMS and legacy equipment
✓LoRaWAN or wired sensor networks
✓A single monitoring platform, configured to your site
✓Automatic carbon footprint calculation against live grid data
✓AI-driven performance reporting across the full dataset
✓Supply, installation, operation and ongoing maintenance
How it works
1
Assessment
We read your half-hourly data and identify where visibility is missing.
2
Install
Sensors and integration go in around your production schedule. Any downtime is planned with you and is usually limited to the switchover.
3
Act
You get the platform, the reporting and a ranked list of what to fix first.
Proof

One site was using 58% of its total energy outside working hours, with nobody in the building, because the ovens had never been switched off and no one had quantified what that cost. Another was running heating and air conditioning against each other continuously. A third had a 60kW solar array sitting switched off and unnoticed. None of these were discoverable from a bill.

Questions we get asked
What data do you need to start?
Half-hourly consumption data, which your energy supplier is obliged to provide and which usually takes a few minutes to download. Twelve months is ideal, three is enough to be useful.
Will installation interrupt production?
Sensors and monitoring equipment install alongside a running operation. There is typically a short planned interruption at switchover, agreed with you in advance. This is the question we get asked most, and the honest answer is that it is a scheduled inconvenience rather than a risk.
Can you work with the meters we already have?
Usually, yes. Retaining existing infrastructure is the first thing we look at, because it keeps the capital cost down and speeds up payback.
What is submetering?
Metering below the level of your main incoming supply, at individual machines, lines or areas. It is the difference between knowing you spent £40,000 last month and knowing which asset spent it.
Service 2 of 5

Power factor correction and voltage optimisation

Guaranteed savings based on physics rather than behaviour change, forecast from your own site data before anything is installed.

The problem

UK grid voltage frequently arrives at industrial sites well above what any equipment on the floor requires. Did you know that UK devices can safely run on 220V because European standardisation grouped the UK’s 240V and Europe’s 220V into a single, flexible range? So when we measure 252 volts coming into a building, that excess does not make anything work better. It becomes heat, it shortens asset life, and you pay for every unit of it.

Why it matters

This is the least glamorous saving available and one of the most reliable. Unlike behavioural programmes it does not depend on anyone remembering to do anything, and unlike a capital replacement project it does not require you to change how you produce. Every month you leave it is money converted to heat in a switch room.

What we do

We deliver automatic voltage optimisation and power factor correction through EnergyAce, who have specialised in this since 2002 and have never once had to pay out against a predicted saving. The forecast is produced from your own site data before anything is installed, and it is guaranteed.

What is included
✓Site electrical survey and load analysis
✓Guaranteed savings forecast produced from your own data
✓Automatic voltage optimisation equipment, sized to your supply
✓Power factor correction where capacity is being wasted
✓Installation, commissioning and verification
✓Post-installation measurement against the forecast
How it works

Equipment goes in, and the saving is verified against the forecast.
Proof

Seven verified installations delivered with EnergyAce, totalling £72,728 in annual savings and 79 tonnes of CO₂. The full table is below, shown by segment.

Questions we get asked
Will reducing voltage affect how our equipment performs?
No. Equipment is designed to operate at a lower voltage than UK supply typically delivers. Bringing the voltage down to design specification removes stress rather than performance.
What is power factor correction?
Power factor is the ratio of the power doing useful work to the total power drawn. A poor power factor means you are drawing current that performs no work, consuming distribution capacity and, on many commercial tariffs, attracting a penalty. Correction equipment brings the two back into line.
Is the saving really guaranteed?
The forecast is produced from measurement of your own supply and is contractually guaranteed by EnergyAce, who have not had to pay out on one since 2002.
How long is payback?
Across the seven installations, between 1.29 and 3.12 years, with most under 2.2.

Solar maintenance and management

Nobody installs a power station and then ignores it for twenty-five years. Generation visible next to consumption, and a maintenance record an insurer will accept.

The problem

Except that is more or less what happens. An array goes on the roof, it generates for a while, and then it becomes part of the building. We have found a site running two arrays with two separate logins and no visibility of one of them at all. We have found a 60kW array that had simply stopped, unnoticed, for long enough that the lost generation ran into serious money.

Why it matters

Sixty kilowatts is roughly twenty kettles boiling continuously. An array that has quietly dropped offline is not a neutral event — it is an asset you paid for producing nothing while you buy the same energy from the grid. There is a safety dimension too: insurers are increasingly concerned about fire risk associated with rooftop solar, and “we assume it is fine” is not a maintenance record.

What we do

We bring existing arrays into the same monitoring platform as everything else on site, so generation is visible next to consumption rather than behind a separate manufacturer login. Alongside that we put a full digital maintenance archive in place, delivered with our partner Auto Watt: every inspection, repair and certificate held against the asset, accessible by scanning a QR code on a plaque beside the array.

What is included
✓Array performance monitoring, integrated with site energy data
✓Consolidation of multiple arrays and portals into one view
✓Underperformance and fault alerting
✓Digital maintenance archive with QR code access at the array
✓Inspection scheduling and records suitable for insurers
✓Generation versus consumption reporting
How it works
1
Audit
We establish what you have, what it should be generating and what it is actually generating.
2
Connect
Arrays are brought into a single monitoring view and the maintenance archive is set up.
3
Maintain
Faults are flagged as they happen rather than discovered at the next site walk.
Worth knowing

For anyone who has tried to produce five years of maintenance history for an insurer at short notice, the digital archive alone justifies it.

Questions we get asked
We already have monitoring from the installer. Why would we need this?
Manufacturer portals show you the array in isolation. The value is in seeing generation against site consumption, in one place, with the rest of your energy data — and in having something that survives the installer going out of business.
What does the QR code do?
It sits on a plaque beside the array. Scanning it opens the full digital maintenance record for that asset: inspections, repairs, certificates, dates. Useful for engineers on site, and useful when an insurer asks.
Do you maintain the panels yourselves?
We manage the monitoring, the records and the performance oversight, and coordinate maintenance through the network. The point is that somebody is accountable for the asset rather than nobody.

Alternative energy and biomass

Where heat is the load, electricity is the wrong answer. Biomass where there is wood waste to feed it, thermal storage where there is generation to bank.

The problem

If your process needs heat, electrifying it is expensive and often impractical. And if you are a joinery, a furniture manufacturer, a sawmill or an estate with forestry, you are very likely paying twice: once to have wood waste taken away, and again to buy the fuel that heats the building.

Why it matters

Heat-intensive processes are where the largest untouched energy costs sit on most industrial sites, and they are routinely left out of decarbonisation plans because the obvious solutions do not fit. Meanwhile the fuel is going into a skip.

What we do

Two routes, depending on what the site has. Biomass boilers where there is a heat demand and a wood waste stream to feed it — the performance is in the filtration, and with the right specification emissions are controlled to a standard that makes the technology genuinely net zero. Or high-temperature thermal storage where the site generates excess energy it currently exports or wastes, turning intermittent generation into something you can dispatch.

What is included
✓Heat demand and waste stream assessment
✓Biomass boiler specification, sizing and supply
✓Wood waste feedstock evaluation, including your own arisings
✓Emissions and filtration specification, with compliance guidance
✓Thermal storage feasibility and sizing
✓Integration with site monitoring so performance is measured, not assumed
How it works
1
Assess
Heat demand, existing fuel cost, available waste stream, site constraints.
2
Specify
The right technology and the right size, with a modelled cost and carbon case.
3
Install and monitor
Performance tracked against the model on the same platform as everything else.
The point about specification

Specification is the whole job, which is precisely why biomass should not be bought on price. Modern systems are a long way from the reputation the technology picked up from a handful of badly specified installations.

Questions we get asked
Is biomass actually clean?
With correct filtration, yes. The negative coverage biomass attracts almost always traces back to poorly specified or poorly maintained installations. Filtration and specification are where the money should go, and they are what we scrutinise.
We produce wood waste. Can we burn our own?
Often, yes, subject to the material and its treatment. It is the strongest case available, because you remove a disposal cost and a fuel cost in the same project.
What is thermal energy storage?
Excess energy is stored as heat at very high temperature and released as heat or converted back to electricity on demand. It suits sites with significant on-site generation and a mismatch between when they generate and when they use it.

Training and skills bootcamps

Funded green industry training that sends your team back with a written action plan for your own site, not a certificate.

The problem

Your team is being asked to deliver on net zero commitments with skills the organisation has never had to hire for. Hydrogen, carbon capture, energy management and industrial decarbonisation are all now board-level topics, and the people expected to act on them are largely learning as they go.

Why it matters

Most training in this space produces a certificate and nothing else. People come back to the same site with the same constraints and no clearer view of what to do on Monday.

What we do

We deliver green industry skills bootcamps, funded through the government’s Skills Bootcamp programme via local authorities, so cost to the employer is minimal or nil. Sessions are delivered by the suppliers who actually build and install these technologies, not by generalist trainers — and every delegate finishes with dedicated supplier time to produce a written action plan for their own site.

What is included
✓Green industry skills bootcamps
✓Hydrogen technologies
✓Carbon capture
✓Sessions delivered by specialist suppliers and manufacturers
✓One-to-one supplier time for every delegate
✓A site-specific action plan per delegate
✓Guidance on accessing local authority funding

What delegates leave with

A document their manager can act on — not a certificate.

Questions we get asked
What does it cost?
Skills Bootcamps are government funded through local authorities. For most employers the cost is minimal or nil, and we will help you establish exactly what applies in your area.
Who should attend?
Energy managers, sustainability managers, continuous improvement and production managers, and engineers with responsibility for plant. The content assumes technical literacy.
Can you deliver training on our site?
Yes, subject to numbers. Get in touch with the size of your team and what you need to cover.

Not sure which of these applies to you?

That is what the assessment is for. Send your half-hourly data and we will tell you which of these five is worth your attention, in what order, and roughly what each is worth.

If the answer is that you are already running efficiently, we will tell you that too.
