I may have misunderstood you earlier - don't want to give you false hope
If you have been given notice month 4 to vacate at end of 6 months then I am afraid that is legal
For my sins I work closely with a local letting agent, I will ask if they have anything suitable in the pipeline
During initial 6 months of tenancy agreement you cannot be given notice and after that if the tenancy becomes a periodic one the landlord may give two months notice and landlord's reason is totally irrelevant
