Hmn, it's pretty standard but it's not totally accentless - the vowels sound slightly Midlands/Northern to me … For completely RP (received pronunciation) British pronunciation I would choose a narrator like Juliet Stevenson In terms of podcasts, the narrator on the BBC's 'A History of the World in 100 Objects' or the David Mitchell video podcasts, or for casual modern British RP, Answer Me This (the 2 main presenters, Helen and Olly, not Martin who is from Birmingham). Those last 2 have the advantage of being very funny.
