If you want to leave your tenancy early because of coronavirus (for example, you are a student and have had to return home to be with your family), you must make sure you end your tenancy correctly.
Check the terms of your tenancy agreement and contact your landlord as soon as you can. If your tenancy does not allow you to end your tenancy you will need to try and come to an agreement with your landlord. Make sure you explain your reasons – they are more likely to be sympathetic if they understand the reasons you need to leave.
If you need to collect your belongings from a tenancy that you have already moved out of, take a look at this Welsh Government guidance first to make sure you are not breaking any rules.
