I'd switch the heating off if you go out and only heat rooms you are in while you are in eg we dont heat the bedrooms at night but leave the doors open after we've finished downstairs. Keep the door shut on heated rooms, draught excluders on them if you can.
Keep your curtains shut, I cant believe how many people leave them open.
Try 20 minutes morning and evening for water, put the stat at 55c. An hour is ages. Put an extra jacket on the tank if you can, they shouldn't emit lots of heat. You could have grown bananas in our airing cupboard when we moved in. It's just barely warm in there now.
Switch everything off, micowaves can use more electric per year running them for the clock than they use to cook.
Dont worry about low consumer items like the phone charger, look at high consumers like irons,electric hobs and ovens, vacuuming and hair dryers.
Google the manuals for the dishwasher and washing machine and see which cycle uses the least energy, then use it religiously.
Look into swapping tariffs if you can leave with no exit fees. Moneysaving experts energy club is whole of market, sometimes it's cheaper to use a separate supplier for each than go for a dual fuel deal.
