Bailiffs visit this week

Can anyone please help, after over 12 months of rent arrears, no fault of covid. Have possession order from Jan.
Have bailiffs going to serve eviction this coming Thursday, what happens if tenant doesnt answer door or has left property without our knowledge??

You need to arrange for a locksmith to accompany you and the bailiff so that they can gain access if the tenant has left or changed the lock. If you think the tenant is going to physically resist the eviction, you need to inform the bailiffs office so that they can arrange for the Police to attend.

Thanks yes have a locksmith accompanying me,dreadful outcome !!
