Your landlord should let you stay at the property while repairs are happening, unless it isn’t practical. They should negotiate with you about moving out while repairs are being completed, letting you know how long repairs are expected to take, and when you’ll be able to move back in. It’s a good idea to get any agreements you make with your landlord in writing  (either by letter, email or text message).
Your landlord doesn’t have to provide you another place to stay, but if they ask to move out, you don’t have to pay rent until the property can be lived in again.
