As a birder who stuggles with gulls. These are the same bird.

As the title suggests - taken a week or so ago in London

Many thanks

Hi Chris,
To me, the barred greater coverts, grey-toned scaps etc point towards this being a 1st-s (2nd cal year) Herring Gull.
Regards,
Harry
 
Sometimes Herring do have a rather solid dark greater covert bar, usually on the outer GC, but occasionally more than just the outer:

Your flying bird probably shows the other wing, compared to the one standing, and there seems to be a difference in pattern, in the amount of solid GC. Together with structure, primary projection and pale inner primaries to mention some character it´s a 2cy Herring Gull like Harry suggest.
