Daylight saving
GMT is London’s winter clock. Right now London is on BST (UTC+1), not GMT. It switches to GMT on Sunday, October 25, 2026 and back on Sunday, March 28, 2027.
IST doesn’t change for daylight saving.
If you mean the clocks in London and Mumbai, whatever they’re on: Mumbai is 4½ hours ahead of London now, then 5½ hours from Sunday, October 25, 2026, then 4½ hours from Sunday, March 28, 2027.
IST here means India Standard Time. The same letters are also used for Irish Standard Time (Ireland in summer, UTC+1) and Israel Standard Time (UTC+2).
