No. We really don't.
People who speak Received Pronunciation (RP) may speak more in this way (look up Jacob Rees-Mogg if you really want to see how stupid it sounds) but they are a small minority of the British people.

Personally my go-to for RP would be Trevor McDonald.
However, RP can sound a bit silly with some pronunciations. The same is true with any accent.
Must be an age thing.
What bothers me is the emergence over the last 10 or 15 years is the new London accent that was previously Thames Estaury in the 90s and before that an actual bona fide London accent that my grandparents had.
The new accent is typified by -ah or -ar instead of -er.
The police recruitment adverts being the best example. Become a police office-aah instead of police office-er.
It wasn't really, though - it was just the first one you heard. Accents are always in flux.
(An interesting comparison for me is the Sex Pistols' car crash Bill Grundy interview against a modern London yoof accent. Major, major change just within my lifetime).
