Just to be able to advise you further could you tell us who your local council is? It sounds like you're being illegally evicted before your tenancy actually ends - your landlord has signed a contract which he is legally bound to he can't go changing his mind.
The proper procedure for evicting you depends on the type of agreement you have with your landlord, and the reasons why the landlord wants you to leave. In most cases, this will usually involve giving you notice and getting a court order. But if you live with your landlord or a member of your landlord's family, the rules may be different.
The only person who is legally allowed to physically remove you from your home is a court bailiff.
In most cases, your landlord should begin by giving you notice that they want you to leave. This might be called a notice to quit or a notice of seeking possession.
Depending on the type of agreement you have, the reason for the eviction, and the type of notice you are entitled to, you should get either:
two weeks' or two months' notice of seeking possession, or
a minimum of four weeks' notice to quit.
After your notice period has finished, your landlord has to apply to the court for a possession order. If you don't leave on the day the court says you should, your landlord must return to the court and ask for a bailiff's warrant. If you remain in your home after the end of your notice period, you may be liable for the court costs that your landlord has to pay to get the possession order and bailiff's warrant.
If at any point in this process, your landlord forces you to leave before the bailiffs arrive then you have been illegally evicted.
