If your home is damaged by flooding, your landlord is responsible for repairing the damage, this includes damage to the structure of the property and keeping the installations for the supply of water, gas, electricity, sanitation and heating in working order.
You must tell your landlord about the need for any repairs as a result of flooding as soon as possible, he or she must then carry out the repairs within a reasonable period of time.
If there has been extensive damage, you may have to leave your home while work is done but only if it is impossible for you to carry on living there. If you can move from room to room while work is carried out, then you will not have to leave.
If your home is so badly damaged that you do have to move out, your landlord does not have to provide you with somewhere else to go.
