Why can my co-signer not be my Guarantor?

Your co-signer might not complete the guarantor criteria. They may not be based in the UK, be a homeowner or may not have sufficient income. Furthermore, may not have sufficient credit history to be eligible to your landlord or letting agent.

Someone who might not be prepared to be your guarantor could be your co-signer as they are taking on a lesser risk than if they were a full guarantor.
