Riding the wrong way up one way streets legally

i went down a oneway street the other day in kensington but the copper just told me to get off my bike, i said i thought there was a trial going on kensington and he said that was rubbish, it was only in a town 'oop north', where is the information concerning the westminster trial oliver?

There is no trial taking place in the City of Westminster. The following six streets are affected in the Royal Borough of Kensington and Chelsea (lifted from the Evening Standard article, which lists only five streets--I haven't been able to find out which one the sixth street is):

Victoria Grove, W8
Thackeray Street, W8
Old Court Place, W8
Holland Street, W8
Gilston Road, SW10

• one more which I couldn't find
