If you are pulling a constant 16 amps on a 230volt ac supply then you will be using 16 x230 = 3680 watts.

3.68 Kwh @12p = 44 pence per hour.

44p x24hr = £10.56

What appliances are you running?

A little rusty but.....

240V RMS * 16amp = 3840w max power or 92.16 KwH per day at 100% useage

£100 per month bills at 12p per KwH indicates you use 834 KwH per month or 34.7 KwH per day. Drawing an average current of 6A over the course of a day (in reality there will be peaks and troughs)

Still quite high, do you have much by way of electric heating / water heating and how much is it used?

Sorry to correct the maths....

£300/0.12p/91 days=27.5kwh per day which is quite reasonable.

27,500w/24 hours=1145W then divide by 230 makes 5A per hour constant.

The 16A trip switch can be overloaded for short periods of time without tripping. It can usually draw 32A for about 20 minutes before tripping so the usage can vary quite a lot.
