Does the gap change during the year?

Yes, because of daylight saving. Until 1 Nov 2026: MST is 6 h behind BST. From 1 Nov 2026 to 14 Mar 2027: MST is 7 h behind BST. From 14 Mar 2027 to 28 Mar 2027: MST is 6 h behind BST. From 28 Mar 2027 to 31 Oct 2027: MST is 7 h behind BST. From 31 Oct 2027 to 7 Nov 2027: MST is 6 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). MST next changes its clocks on 1 Nov 2026 (back 1 h, to UTC−7), then on 14 Mar 2027 (forward 1 h, to UTC−6).
