UCL’s winter break takes place from 5.30pm on Wednesday 23 December 2025 until 8am on Monday 5 January 2026. Please read our guidance on closing workspaces and notifying Security about any out of hours access requirements.
As we head towards the end of the calendar year and many of us take a break away from UCL, please ensure that you and your teams are prepared to close and switch off safely by the end of Tuesday 23 December.
This article also has information on organising out of hours access to a specific building if this is required, including the deadline to submit any requests for access.

Guidance on closing laboratories and making constantly running equipment safe
The following procedures apply to the UCL’s main sites, defined as all buildings except those of the postgraduate medical institutes and sites away from central London. Before leaving for your break, Laboratory Superintendents and others where appropriate, unless otherwise instructed by the Head of Department should ensure that:
- all lights, heaters and computers are switched off in their department.
- all gas and water taps are turned off and that hoses connecting apparatus to water taps are securely wired both to the water supply and to the apparatus.
the Security Office has received by 12pm (midday) on Wednesday 17 December a copy of a list of places, such as laboratories with constant operating equipment, where there is a possible danger from flooding or fire via securitysystems@ucl.ac.uk
the Security Office has received by 12pm (midday) on Wednesday 17 December written details via securitysystems@ucl.ac.uk of persons who can be contacted in cases of emergency (other than those already on the Control room database).
Laboratory Managers can use this form to let UCL Estates know what level of heating and venting their laboratories need over the break:
Closing your lab for the break? Let UCL know
Out of hours work: stay in touch, stay safe
We’d like to remind everyone about the need to take care when working during periods of closure. Any procedures which have been assessed as having a significant level of risk should not be carried out by persons working alone. We also ask you to consider the environmental impacts of running campus buildings for a very small number of occupants.
If any members of staff are unsure of their personal access to a building out of hours, they can clarify this by contacting Security Systems. You can also download SafeZone, UCL’s mobile app that allows all students and staff to alert, contact, and directly speak to the Security team in the event of an emergency.
UCL Security would like to stress the importance for individuals to maintain internal security within their departments. Any incident which appears suspicious should be reported to the Security Control Room on the UCL Emergency Number (020 7679 2222, or extension 222 from an internal landline) or via SafeZone. Reporting via SafeZone works across all’UCL locations. If you want to contact the security desk for Marshgate and One Pool Street buildings in the Olympic park, dial +44 (0)208 0168 555 or 68555 from a UCL telephone.
