As a real people watcher with a huge interest in British social history I find threads like this genuinely fascinating, but I am reluctant to post too much on them as some people always get incredibly defensive and chippy, and they can end up quite difficult threads. I am in complete agreement with what Emphatic said though.
These days (and since the 2nd World War generally, the classes have become much more blended, and (apart from perhaps those at the very very top and the very very bottom, both of whom pretty much perpetually live in their own untouchable bubbles) the subtle traits and behaviours between classes have become muted and less obvious in the last 30-50 years. The majority of us share a mix of watered down class habits and expectations blended with our own personal traits for tidiness or otherwise. We probably don't even realise on any conscious level that we are doing things for deep-seated reasons of class though.
The WC trait of excessive cleaning and tidying probably is/was also borne out of absolute necessity, as in a very small house with a very large family things could very quickly get out of hand. In huge rambling houses you can be free to be a messy git for a few weeks before it really catches up with you.
And of course in times gone by there would have been staff to clean up for you, and you'd be orf doing something fabulous and enriching like perfecting your serve, or reading some impressive hefty tome in French, and networking with other apparently fabulous people.
I always think that plaque you see in gift shops that says 'Dull women have immaculate houses' has its passive aggressive roots planted firmly in the British class system. Thankfully I've know plenty of women who disprove that sentiment from both angles, and (almost) all classes.
