Does the gap change during the year?

Yes, because of daylight saving. Until 27 Mar 2027: BST is 10 h ahead of HST. From 27 Mar 2027 to 30 Oct 2027: BST is 11 h ahead of HST. From 30 Oct 2027 to 25 Mar 2028: BST is 10 h ahead of HST.

HST does not change its clocks. BST next changes its clocks on 28 Mar 2027 (forward 1 h, to UTC+1), then on 31 Oct 2027 (back 1 h, to UTC+0).
