Faulty meter?

Hi,
Just wondering what kwh consumption is average / reasonable p.a.?
We seem to be consuming around 12,000 kwh p.a., which seems awfully high for two people ( oil fired central heating, electric cooker)…
Thanks,

“with the average consumption in 2017 being as low as 3760 per household”

May be worth installing a smart meter if you don’t have one, so you can see your current usage etc…

Or purchasing the relevant one of these:
