If you have signed a six month lease can the landlord want to move back into the house after one month?

The landlord can only seek possession during a fixed term of a tenancy (for example the first six months of a shorthold tenancy) on the grounds shown in italic type. Mandatory grounds - for which the landlord must have advised the tenant in writing before the tenancy began that s/he might be seeking possession: * Your landlord used to live in the house and wants it back (at least two months notice must be given) * The house has been repossessed and the mortgage company need to sell the house with vacant possession (at least two months notice must be given) * Your house is needed for a minister of religion and you were given notice of this when you moved in (at least two months notice must be given) * The tenancy is for a fixed term of not more than eight months and within a year before you moved in the house was let as a holiday home (at least two weeks notice must be given) * The tenancy is for a fixed term of not more than 12 months and within a year of moving in the house was let to students by the place where they were studying and you were given written notice of this before you moved in (at least two weeks notice must be given).
