Bjbear. I think it is a chiffchaff but always find these 2 difficult. I am making a comment in order that it doesnt disappear and you will hopefully get other opinions.
Actually, it looks like a female Blackcap to me!! See it's little brown cap?
Legs look darkish so I'd go with Chiffchaff too!
I was having the very same problem over the weekend. Good luck
Chiffchaff I would say. Here's a link.
I usually go off the song. But in this case the distinct cresent under the eye is the clue.
Yes, Chiffchaff (which is a warbler!).
A combination of subtle features all combine together to help with the identification:
-The eye ring is only obvious below the eye, contrasting with dark cheeks.
-The wings appear relatively short (though very difficult to judge from this angle).
-The supercilium, although quite long, is not particularly distinct.
-The legs are dark.
-The overall appearance is of a relatively 'dingy' birds without clean white underparts or any obvious yellow.
Lovely little visitor. Well caught
Legs aren't a positive feature...
Also, always use more than one feature. Especially if that feature is a variable one.

This is a cartoon I drew (years ago) about the perils of relying on just one identification feature:
