An excellent shot of Reed Warbler!..a somewhat compressed posture from my experience, normally looking more attenuated!....and what appears to show a very short bill for scirpaceous? Can see how it might confuse those with a fertile mind.
Overall colouration, rather plain looking tertials, uneven spacing to primary tips, tertials not overhanging the secondaries, and old looking primaries (as opposed to neat, crisp new ones with prominent white tips) all support reed warbler.

I think the colouration fits reed warbler better than any other acro, PP is fine for reed, bill shape admittedly is strange, but look at the nostril shape, also, much better for reed than marsh.
Let's not forget that it was photographed in London too. That doesn't rule out marsh or anything else, but it makes reed much, much more likely.
I would second that. Admittedly the bill is the short side for Reed warbler, but its shape does not favour Marsh warbler at all (the latter species typically shows a thicker based billn the lower mandible being oftn noticeably "swollen").
Here is a collection of Marsh warbler photographed recently, note the difference in overall colouration (grey-olive-straw colours in Marsh vs rich brown in Reed), bill shape and wear of plumage (especially the clear white tips to the primaries and the broad fringes to the tertials in pristine condition).

Hello Tib,
The swollen mandible is not well presented because the head is bended a little bit and not perfectly side on , but noticeably very thick and short, also the 3rd pic of the first MW set the bill of the MW is also does not show the swollen bill?

Nostrils are quite round in marsh and quite oval in reed - nicely illustrated here:
