@alwayshavebeenfemale ((((HUG)))). I'm very sorry to hear about your DH/DW. (I'm going to use DH until you tell me otherwise or it gets too messy with acronyms) The last thing you need right now is to be worrying about sodding bills.
just a few suggestions...
check that your 'estimated usage' for this year (that they're using to calculate things) is inline with your actual usage for last year. Some people have found the companies are estimating usage WELL above previous years actual usage!
I'm sorry, but this is a delicate question. Was your DH using any medical equipment that had to be plugged in?
Are you on a fixed tariff or on the variable? How long ago did that change?
(just while I think if it too, have you applied for the single persons rebate on council tax?)
there are a LOT of threads on energy saving for this winter, have a look through and see what you could do. In an old stone house you possibly/probably would benefit from long, heavy curtains over your external doors, sealing some of the windows closed, using film on the windows & heavy curtains. (Sorry hard to know what you do/don't have in place). Rugs if you have hard floors.
do you have a fireplace/wood burner? Getting dried wood delivered is worth the cost this year & gathering & drying for next year.
then obviously layers/slippers/thermals etc
electric heated throws are 'all the thing'. Apparently the thin cheap ones are good as they drape around your body better & apparently they're cheap to use.
electric blanket for your bed?
taking up knitting/crochet, it keeps you warm while you do it, you can make all kinds of things AND it occupies your mind!!

I wish we could just 'live chat' on here sometimes.
look after yourself xx
