Universities
We expect that the majority of university students, other than those who need or choose to remain at university, will now have returned to their family home during the ‘student travel window’, , although they are permitted to temporarily move to a “vacation household” during the period that began on 3 December up to 7 February. We have published guidance on how they can do so safely.
We have also published guidance to universities and students on how students can return safely to higher education in the spring term. This guidance sets out how we will support higher education providers to enable students to return as safely as possible following the winter break, by staggering this process and to facilitate testing for all.
If you live at university, you should not move back and forward between your permanent home and student home during term time.
Universities should follow guidance on reopening buildings to ensure they have safety measures in place to minimise the spread of the virus.
If you’re a student, you can meet in groups of more than your household as part of your formal education or training. Students should expect to follow the guidance and restrictions. You should socially distance from anyone you do not live with wherever possible.
