Ask an Property Solicitor. Get an Answer ASAP.
A tenant may appeal within 21 days of the order being made.
If they fail to leave today as per the order, you would need to apply for a warrant of possession.
I would suggest you instruct court bailiffs to apply for the warrant and the eviction for you e.g. https://thesheriffsoffice.com/instruct-us/instruct-us-evict-tenant-squatter
