If an outright possession order is granted you have to leave the accommodation by the date given in the order.
If you have an assured shorthold tenancy the date is usually 14 days after the date of the court hearing. However, if you are in an exceptionally difficult situation (such as if you are ill or have very young children) you may be able to convince the judge to delay this for up to 6 weeks. If you want to do this you should tell the judge about it at the hearing.
If you have a secure tenancy with the council or an assured tenancy with a housing association, the possession date is usually 28 days after the date of the hearing.
If you have not left once the date given in the possession order has passed your landlord can only evict you by applying to the court for bailiffs to remove you from the property and change the locks. It usually takes two to four weeks before the bailiffs do this, but you may only get a few days’ notice.
