Who it's for
If any of these apply to you, miOhm was built for you.
You've been asked for a carbon report
A tender or enterprise client has requested your Scope 2 emissions data and you don't know where to start.
Your energy bills are unpredictable
You know your energy costs are significant but you have no visibility into when or why your consumption spikes.
You're aware of CBAM or ESOS
Regulatory deadlines are approaching and you need to be able to demonstrate your carbon footprint with credible data.
You want to win more tenders
Enterprise clients are increasingly filtering suppliers by sustainability credentials. You want to be ahead of that curve.
How it works
No sustainability expertise needed. No spreadsheets. No consultants.

miOhm gives UK SMEs the same quality of energy and carbon intelligence previously only available to large enterprises.
Half-hourly consumption dashboard
Visualise your electricity usage across every 30-minute period of the day. Toggle between 7, 30, and 90-day views or pick a custom date range to understand short-term spikes and long-term trends.
Peak vs off-peak breakdown
See exactly how your consumption splits between peak and off-peak hours every day. Stacked bar charts make it immediately clear when your business is using the most expensive, highest-carbon electricity.
Automatic Scope 2 carbon calculation
Your Scope 2 emissions are calculated automatically using DEFRA grid emission factors applied to your real half-hourly meter data — not estimates or industry averages.
Scope 2 carbon report (PDF)
Download a professionally formatted PDF report aligned to the GHG Protocol Corporate Standard. Accepted by enterprise procurement teams for supplier carbon data submissions.
Report history
Every report you generate is logged with its period, total emissions, and generation date. Re-download any previous report instantly — useful for audits, tender submissions, and board reporting.
Energy cost estimator
See your estimated annual energy spend alongside your carbon figures, calculated from Ofgem average unit rates. Hover any bar on the chart to see the estimated daily cost of your consumption.
Week-on-week trend indicators
Every summary card shows how your consumption and emissions compare to the previous week — so you know immediately whether you are improving or need to investigate.
Tariff insight with donut chart
See exactly what percentage of your energy is consumed during peak hours with a live donut chart. Get a personalised monthly saving estimate for shifting flexible loads to off-peak periods.
Anomaly highlight with cost estimates
miOhm automatically flags your three highest consumption days, shows how far above your average they were, and estimates the cost of each spike — helping you identify faults before they compound.
Annual carbon projection
Projects your full-year Scope 2 emissions at your current rate, benchmarks them against the UK SME average, and shows a progress bar so you can see at a glance where you stand.
Carbon reduction target tracker
Set a percentage reduction target and a deadline year. miOhm tracks your progress with a live progress bar and tells you whether you are on track — turning reporting into active management.
Peak usage email alerts
Get notified automatically when your consumption spikes more than 20% above your 30-day average — so you can investigate equipment faults, leaks, or inefficiencies before they compound.
The regulatory context
This isn't optional. The timeline is set and the requirements are clear.
