Hello Kev, welcome to A4A.
Your landlord always has the ability to serve you notice to quit, with a minimum of 12 months notice expiring on the last day of the rental period. So if your tenancy runs 1st January and you were served notice today your tenancy would end 31st December 2011.
It's also perfectly reasonable for your landlord to offer you a new tenancy at any time which, were you to accept it, would immediately end the previous tenancy.
It's not reasonable to characterise any of that as bully boy tactics unles the landord makes the offer of the new tenancy contingent on your immediate acceptance or something like that, in which case I'd agee, but even then it might not be worth the fight as the change is inevitable and all you're losing is a few months of notice.
A much more interesting question is whether the enforceability of the agreement's new clauses could be challenged, because the landlord can't impose arbitrary rules.
So what specifically do you object to?
