Why you need to look at your electricity bills

Another vacated property means another electricity bill. The trick on their part is that as we're out of contract they can bill us the massive out-of-contract rates until it gets finalised. In this instance being charged 20p per kWh for both night and day rates.

The first bill arrives post contract. It's been estimated that this empty unit used 100 night units @20p and 400 day units @20p as well as 50 night units at the new contract price of 10p and 400 day units at the new price of 15p.

Nuh-uh we used 50 night units and 300 day units. A new invoice is sent and we're credited out 100 night units @10p and 500 day units @15p. Can you see the flaw?

We were charged for the 50 night units we used at 20p (£10)* and then an additional 50@20p and 50@10p (£15 total) and credited 100@10p (£10)

We were charged for the 100 day units we used at 20p (£20) and then an additional 300@20p and 400@15p (£120) and credited 700@15p (£105)

Or £30 over

At least when I pointed this out they instantly saw it and another new invoice is on its way. Given the way Electricity Suppliers change prices mid-invoice I do wonder how many in the same situation would  just note the credit and think it okay.
