Is £ 819.87 for 9 months of electricity too much?

A house with gas hot water & heating shouldn't be using that much electricity. Can you confirm there's no water immersion heater in use. I pay 10.9p per kWh by the way!

Definitely no immersion heater

Then you really need to do some detective work to find out where all that electricity is going. Unless you're leaving a 70" OLED TV on all day long, there's something eating up the kWh. A cheap realtime energy monitor that clips on the feed into your consumer unit will help diagnose the culprit.

Or just look at the flashing red light on the meter.  In the daytime with just the fridge, freezer and a few items on standby or charging, the background consumption should be somewhere around 150 - 300W.  The light will tell you how many impulses (flashes) correspond to 1kWh.  If says '800 Imp/kWh' then 300W would mean a flash every 15 seconds, so if it's doing St. Vitus's Dance you'll know that something is using far more.

You can then narrow it down by switching circuits off at the consumer unit one at a time and seeing what stops the rapid flashing.
