Does the gap change during the year?

Yes, because of daylight saving. Until 28 Mar 2027: BST is the same time as GMT. From 28 Mar 2027 to 31 Oct 2027: BST is 1 h ahead of GMT. From 31 Oct 2027 to 26 Mar 2028: BST is the same time as GMT.

GMT 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).
