Tenancy terminated due Covid19

General Discussion

My letting agent has just advised me that a tenant has withdrawn from a tenancy days before due moving date after the property was held for a month with the reason because of Covid19. The tenant was an overseas tenant and decided against moving to UK because of high infection rate.Whilst I understand the reason behind the change of mind it seems wrong that a tenant can plan to proceed with a tenancy then have a change of mind a few days prior and the only loss is a reservation fee which the agent keeps and the landlord has the cost of a void period.
Surely there should be a financial penalty paid to the Landlord if a tenant decides to terminate prior to moving in after the property has been taken off the market and unavailable to other tenants.
