Meter Energy Monitor

I actually did set it up as 13:00 not as I said 00:13. But I will reorder one and the worse case I can just use old fashioned math. 

Thanks for your help much appreciated

Surely you can work it out yourself via maths?

If you have a device that eats 200w of power if you leave it running for one hour and your unit rate is 10p per hour (for argument's sake) then that device will cost two pence per hour.

Or am I missing something?

The rating plate on an appliance may bear little resemblance to how much it actually uses.

For example, the amount of power a computer uses depends on what you are doing with it at the time.

I have a similar meter to yours - I find it quite accurate.

Do you have an electric heater, that say has 2 settings, for example 1000W (1kW) and 2000W (2kW)

If you do plug it into your meter - first do the low setting, and see if meter shows (for my example) close to 1000W - say run it 2 minutes.

Then repeat at higher setting and see that meter shows the higher amount.

Once you confirm that the meter is showing the accurate watt reading, you could say run the heater at 1000W for say 20 minutes - set the thermostat at the highest setting so that the heater runs continuously for the 20 minutes.

At 12.43p/KW - a 1000W heater will use, around 333W (0.33kw) of electricity. At 12.43p/kw, your meter should show 4.14p
If the meter is in pounds and pence, then I suppose it would show 0.04

You can do the same experiment with a lower watt appliance, but the heater will give you a fast answer if your meter is working or not.

As example, I have a fan in my home office which (accurately) is rated at 35W - which means I would have to run it say 9.5 hours to get a similar result of 4p. 

Hope that helps - good luck

At 12.43p/kWh - a 1000W heater will use, around 333Wh (0.33kWh) of electricity. At 12.43p/kWh, your meter should show 4.14p.

FTFY !

BTW, anyone getting electricity at only 12.43p/kWh is doing remarkably well these days.

Unfortunately My tariff ends in a month, going to be hit with about £250 more a year I think.
So looking at why my bill so high for a 1 bed flat, hoping to cut the cost somewhere
