I changed my dual fuel tariff with EON recently. New one is fixed until
next October. With my new deal came a "Energy saving monitor" - it tells me
how much electricity I'm using.

I've checked the readings of the monitor against my meter readings. The
monitor tells me I'm using approx. 15% less than my meter readings.

Are these monitors that inaccurate ? Or could my meter be over reading my
usage ?

Any thoughts ?

TIA
