It is possible to get out of the agreement at any time if you can come to a mutual agreement with your landlord. This is called ‘surrender’. To be valid, both sides must agree and it’s always best to put what’s been agreed in writing so everyone knows where they stand. If you have a joint tenancy all the joint tenants and the landlord must agree to the surrender.
If your landlord has already served you with a notice to leave your property and you find somewhere else to live before the end of that notice, your landlord will probably be happy for you to leave early. It is however always best to speak to your landlord and, if they do not agree, you will still need to end your tenancy using one of the methods above. Otherwise, you might find that you continue to be charged rent after you have left.
If you are not sure whether you need to serve a notice, or whether you have surrendered your agreement, get advice urgently.
