Hi @Natalie837 ,
The gov.uk site should tell you what you need to know https://www.gov.uk/guidance/tier-4-stay-at-home#travel
Nb "Traveling to a Tier 4 area from a Tier 1, 2 or 3 area
You should not travel into a Tier 4 area from another part of the UK except for legally permitted reasons such as: work...." (and a few other exceptions.)
Scroll down & you will read "Guest accommodation providers.... may remain open for the specific purposes set out in law......" - i.e. for people who need to travel for essential reasons; work, moving house, caring, funerals etc, - not leisure/holidays/family jollies!
