Our tenancy agreement is due to expire at the end of November. the Agency asked us on line if we wanted to extend a further 12 months. we replied yes then we discovered we are pregnant with our first child! we now want to change from a one bedroom to a two bedroom. but the agency say that even though they have a 6 month delay on tenancy agreement renewals – because we indicated to continue on email that is legally binding and we can’t be released from our tenancy. we haven’t signed a new tenancy agreement and feel that we are now on a rolling tenancy and can give a months notice. anyone know where we stand legally?
