I live in a 2 bed flat and have been running 3 storage heaters on an economy 7 tariff for most of winter.
I have taken readings 6 weeks apart, and have calculated we’ve used £130 on the night rate alone (£180 total) . The only significant usage at night is the 3 storage heaters and an immersion heater.
This seems way higher than previous years! Luckily it’s warmed up now so I’ve switched them off.
I’d be interested in knowing anyone else’s rough monthly with storage heater use?
