£19.90
Your bill went up again. Do you know which appliance is to blame? UK energy prices keep climbing — and most of us have no idea which of our appliances is quietly driving the bill up.
Standby power and forgotten appliances can account for a meaningful chunk of a typical household's electricity bill — often without anyone realising. This monitor takes the guesswork out completely: no more guessing which switch to flip, just real numbers from your own home.
