I need some help identifying which type of warbler this is please

QCan you please confirm whether this is a Willow Warbler or a Wood Warbler? Peter Stockton

ALeaf warblers (the small, usually greeny-brown ones in the genus Phylloscopus) are a tricky group. Of the regular British species, Chiffchaff and Willow Warbler are arguably the hardest to separate and Wood Warbler is a tad easier (if you can get a decent look). One thing we can say for certain, is that this is not a Wood Warbler, as the tail is too long and the wings are too short relative to it; the belly is just not pure white enough; and the supercilium (pale eyebrow) is not strong enough. This is either a Willow Warbler or Chiffchaff, and it would need a better look at the projection of the primaries of the wing (the pointy flight feathers; longer on Willow than Chiffchaff). However, it ‘looks’ like a Willow Warbler, with the bolder longer supercilium of that species. As Dominic Couzens would say, Willow Warbler is ‘high brow’ (eyebrow) and Chiffchaff is ‘riff raff’!
