There are two kinds of electricity monitor to have fun with. The first is a little gadget that goes in the wall socket and allows you to plug your TV (on standby), computer or other appliance into it to see how much power it uses over e.g. 24 hours. The other kind ‘clamps’ onto your electricity meter, with a display that can be located elsewhere to allow you to monitor electricity you are using. Turn on an electric oven to see it zoom. Both are really useful for encouraging switching off.
Electricity monitors work alongside your existing energy meter (but shouldn’t be confused with smart meters or prepayment meters).
According to the Energy Saving Trust you could find that your energy usage drops by between five and 15% in the first year of using an energy monitor, which could be a saving of £25 to £75 on a £500 bill.
