Most private tenants have an assured shorthold tenancy. If this is the case, your landlord does not need to have a legal reason to evict you. If they want to evict you, your landlord must give you the correct amount of notice and must follow the correct legal procedure. If the correct procedure has been followed, the courts will have to give possession to your landlord.
Think carefully before you decide what to do. If there’s not much time left on your agreement, your landlord might decide to give you notice rather than do the work. But if you’ve still got months to go, and your home is unsafe, it may be worth taking action – even if it means that you have to leave at the end of your contract.
Beware: If your landlord can prove a legal reason for eviction (for example because you have been withholding rent) your landlord may be able to evict you more quickly. Depending on the seriousness of the problem, it may be unwise to take action in this situation. Always try to talk to an adviser before you decide what to do.
