Landlords and tenants have certain rights and responsibilities - even if they're not mentioned in the tenancy agreement. Some rights and responsibilities apply to all tenancies. Others are set out in the legislation that applies to the particular type of tenancy you have.
Any written or verbal agreement you have with your landlord can only add to the basic rights that come from legislation. Your tenancy agreement cannot take any of these rights away, regardless of what it says. If a landlord (or someone acting on their behalf) tries to take away your legal rights, they may be guilty of harassment or illegal eviction.
