I think space is key in this issue too.
I live in central Tokyo where apartments are miniscule and storage space is like gold-dust. DH, DD(6), DS(3) and myself live in a small (think tiny, then halve, then halve again and you'll about have it) 2-bed apartment.
I have no choice but to be ruthless with what we buy/own/keep.
That said, I don't find it at all boring/dull/unhealthy/abnormal/any other derogatory word for clean and tidy that people may mention to have a spotless house apartment.
In fact, I quite enjoy that liberating feeling that someone else wrote about that comes from knowing that I use and need everything I own (pushes firmly out of mind the enormous suitcase of baby clothes that are just too damn cute to throw/donate/sell), well, almost everything.
I work full-time and get naff all very little help from DH when it comes to housework. What works for me is daily routine: So:
After work, pick up DC from nursery/after-school club, dinner goes on,
laundry in washing machine,
school bags unpacked and packed for next day,
Make sure DD is settled with homework, DS with entertainment of some sort
Finish making dinner (bulk cook at weekend and freeze)/ eat / wash & dry dishes and make sure all kitchen surfaces are clean, all food put away, floor has no food stains etc
Bathe DC
Washing finished by this point, so hang out and/or dryer on
1 hour with kids (play, chat, story, bed)
Ironing previous day's laundry, folded & put away
TV time, evening tipple, make sure cushions plumped and room looks nice and bed
Bath cleaned daily when I am in shower in the morning (Japan, so wet-room style bathroom).
Toilet room is cleaned with disposable toilet wipes (cheap as chips here, assuming you can get them in UK?) every 2 days.
Beds made every morning, clothes hung up after they're taken off (DC trained, DH luckily naturally tidy-ish).
Hoover every few days (apartment so small takes 5/10 minutes to do entire place).
Big cupboard blitz during holidays.
Sorted. hth. Someone.
