Chiffchaff?

J spotted this little bird from the bathroom window early - for us! - this morning - another surprise garden visitor we’ve not seen before. ‘Picture this’ gives options of chiffchaff or willow warbler - please do say if you know.
The Anglica, grown from seed is clearly popular with the birds as well as the bees
Preparing this evening for a week away in the Lake District so I’m not sure I will get to enjoy your journals tonight- I’ll be playing catch up.
Thank you for your visits, comments and for the generous sprinkling of hearts and stars, they really are appreciated
