Energy monitoring uncovers a 38% overcharge
Intelligent Gas and Power teamed up with Envisij to prove that an industrial campus was being overcharged by 38%. The evidence unlocked a £230,000 refund and much lower ongoing bills.

The challenge
What Intelligent Gas & Power needed to solve
- A large industrial campus had been in dispute with its supplier about suspected overcharging for years.
- Multiple 11kVa to 415V transformers made it hard to see what each tenant was actually using, especially outside working hours.
- The client needed to compare billed consumption against real usage, all the way down to individual circuits.
- Sub-metered data from the site had to be combined into a single total for the whole campus.
Background
About Intelligent Gas & Power
Intelligent Gas and Power is an energy broker that supports commercial, industrial and public sector clients. They partner with Envisij to give clients clear, real-time visibility of energy use at half-hourly meter level.
The solution
How Envisij helped
- Envisij worked with the facilities team to place monitoring points that captured both tenant level and whole site consumption from the same hardware.
- Half-hourly data from the contracted Meter Operator and Data Collector was sent to Envisij automatically each day.
- The Envisij dashboard put billed consumption and actual site consumption side by side.
- Trends were tracked for months to build a rock solid evidence pack.
The outcome
What changed
The data showed actual site consumption running 38% below what the supplier was billing. The client gathered a full year of readings, then escalated to the Energy Ombudsman when the supplier pushed back. An audit uncovered a long standing setup error in the half-hourly meter, and a £230,000 refund followed.
“Envisij was a game changer. The half-hourly data made discrepancies obvious within weeks and gave us the precise, undeniable evidence we needed to confront the supplier.”
