Great list, bossykate.
To add, always try to cook for more than one meal and freeze extras.
For tidying, leave things at the bottom of stairs that need to go upstairs and vice versa. That way, they accumulate into a pile until you find the time to bring them up/down to be put away, all at once.
Direct debits, as much as possible.
Cleaning materials permanently stored in kitchen and bathroom. You can do bits as you use the rooms eg for bathroom, wipe down mirrors and taps damp with condensation. Wipe floor when dcs are having their bath. Throw bleach in toilet before you go for work.
Hoovering is ambitious, if you can. Otherwise, a dustpan and brush is great for spotcleaning and cosmetic jobs.
This will give you a half-bearable house, not immaculate.
