This year British Summer Time (BST) ends at 2am on Sunday 26 October 2025 and the clocks will go backwards one hour, to 1am Greenwich Mean Time (GMT).
This change impacts CDSP systems as follows:
- UK LINK, IX, GES, EFT, CMS and DDP – system clocks go backwards to GMT at the normal time of 2am BST – no outage is required and there are no anticipated customer impacts.
- Gemini – system clocks go backwards to GMT at the normal time of 2am BST. Please note there will be a restricted service during the first hour of GMT and some Gemini business processes are impacted.
More information about the Gemini business processes impacted by the clock change is available in NGT's Gemini clock change document below.
