No smart meter unfortunately, We were on estimates for a while previously but have started giving readings every month. We were apparently underpaying for a while last year so built up some arrears which are factored into the current direct debit they have been suggesting. I am over simplifying this as this was its own issue at the time after we were switched over to Eon and there was some miscommunication.
We have a tank which I believe is immersion, will double check sometimes I get these things crossed in my head. We have heaters around the house I think they are storage? They are electric. We do not use them however and have not turned them on at all so far this year, our flat is relatively well insulated for the most part and pretty cool during the summer so no need for AC and the like(Ground floor no direct sunlight).
We typically only use the heating during the winter minimally and I will be making some changes around the flat around windows and doors to minimise that usage this year.
In terms of our other bills though just for clarification, outside of 2 sim only contracts/home broadband/water/food/tv license/Car insurance/fuel(Low usage as work right next to where I live)/rent(low compared to anywhere in my city as my landlord is a godsend) we don't have much else. I have almost no debt just one loan payment a month with less than £600 remaining. We own our car/phones everything outright otherwise.
In terms of what we have in the house, I have one computer in the house (quite old now not spent money on this hobby of mine in years), one tv(almost never used). Mum has a tablet/phone. We only have an oven/hob/washing machine/fridge/toaster nothing fancy. No pets no miscellaneous products.
I wish we had a more efficient boiler/tank or something I'm sure that would be significant as I know immersion/storage are costly.
Also no offence taken, I hope the above helps there honestly isn't much I've missed out, its just been a chain of unfortunate events that have lead us into this situation.
