Energy management specialist Marshall-Tufflex is flavour of the month with one customer after saving the company more than £65,000 in just one week.

The client - a manufacturer of heating products - installed a Marshall-Tufflex Sinergy e-Tracker sub-metering unit to get an in-depth view of its energy usage over one week.

When the stats were examined the company discovered its electricity meters were making incorrect readings. The matter was taken up with the power supplier and a refund of £65,000 issued along with an assurance that future bills would be correct.

“To have saved the client so much money by doing something so simple is amazing," said Marshall-Tufflex business development manager Kristie Donachie.

The Sinergy e-Tracker is a portable kWh meter allowing users to monitor incoming power supply, specific circuits/equipment etc to show the pattern of demand over an hour, day, week or month.
