Does the gap change during the year?

Yes, because of daylight saving. Until 28 Mar 2027: ART is 3 h behind BST. From 28 Mar 2027 to 31 Oct 2027: ART is 4 h behind BST. From 31 Oct 2027 to 26 Mar 2028: ART is 3 h behind BST.

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). ART does not change its clocks.
