How do you tell if someone is LOWER, MIDDLE or UPPER class?

By studying and analysing their speech.

Doesn't really work. People can learn to adopt different accents as they progress in life. I started out working class and if you believe we die in the class we're born, I guess I still am. But my profession is middle class and I don't have a regional accent.

I'm not poor and I vote UKIP?
Are you ok?

The really posh areas are consistently blue, UKIP only does well in depressed coastal ex-fishing villages and northern hell-holes where people have fears over mass migration.

It's important to realize that people in poor economic areas lean toward UKIP because they want someone to blame for the struggles they face in society and have been led to believe this blame falls on immigration.

I consider upper class people to be the gentry,telling apart the other groups is harder but house size, speech, level of education of parents, annual income, and an individual's culture can be used to identify the class of a person.

Speech is often the single most obvious and readily apparent indicator of class. No matter how hard some people might try to lose their native accents, they inevitably slip up and you can often detect a rare hint of their original accent. I can tell when someone is trying really hard to speak English properly despite not being from the south, I pay very close attention to their pronunciation, their choice of vocabulary, their grammar and sentence structure, and their overall attitude and the way they conduct themselves, including the topics they talk about and whether they abide by refined conversational etiquette.

Yes, you die in the class into which you were born. Class transitions occur very slowly over the course of several generations. Class transitions can never occur within one's own lifetime. Class has nothing to do with your profession your last sentence is invalid, because class isn't defined by your job.

It's not just about your accent. There's so much more to it than the way you pronounce words. As I've already outlined, I like to analyse various aspects of people's speech and overall behaviour, not just the accent.
