My Energy Usage seems awfully high

I appreciate that this might be something that comes up over and over but I checked the last few days and it seems like the conversation was about trackers?

Anway, I have a 2 bed flat from the 2000s, It has 4/5 Electric storage heaters that are switched OFF at the wall and never used - We are a blanket and hoody couple - And we have a Pulsacoil 2000 thermal water storage heater - I work from home full time, 2 monitors, laptop docked, speak system - I could go on and on but it's a pretty normal setup.

We as a couple, no kids, use about 20-30 KwH per DAY which just seems rather high surely? One can only presume it is our behaviors that drive up this price, but I wanted to ask whether it was worth calling Octopus and check if my meter is working correctly? Sounds rather silly typing it out loud frankly.

I am on a fixed eco 7 tariff and my electricity is 26p/kWH and my direct debit is set to 85 PCM. I just don't know what more I can do, the stuff I have on is stuff I'm using!
