The new BA 321Neo's do not have the exits for 235/240 pax like EZY do with 240 pax.
EZY's have the 4 larger overwing exits - BA have 2 which means 220 max pax (but the other 2 exits maybe fitted but deactivated as can be offered by AB)
As you may know the new 321neo is offered with a number of exit configurations with varying doors and/or overwing exit windows
