I take it your landlord told you this ?

and I have been told that Jenalyn will need reference checking or a guarantor to be named on the tenancy agreement.

Accommodation (renters) If the sponsor rents a flat or house, the tenancy agreement should be provided. If the applicant is not a signatory to the tenancy agreement, then an additional statement from the landlord (or estate agent) should be provided that attests to his agreement that the premises will be occupied by an additional person. If an existing tenancy agreement is to be used, it should have at least six months before expiry. If the tenancy agreement does not have at least six months before expiry, then an additional statement from the landlord showing intent to renew at the same terms should be provided.
