Either Marsh or Willow Tit.
No interactions present.
Upper area of wing towards back also looks paler than outer edges. Flanks look rusty buff rather than grey buff. Both of these would be consistent with Willow Tit according to the books I have just checked.
Wish we had them over here (north of Ireland)
As far as it is posible to say from these photos it certainly looks likely to be a Willow Tit (pale wing panel, all white cheeks, large bib, dull black crown).
If I'm lucky enough to see a tit that looks similar in my area I can pretty much guarantee that it will be a Marsh Tit now because there are no longer any Willow Tits in the area (North London).
