Yes, but if you have shared finance, we need to be extra sure that having this loan wouldn't put either of you under any financial strain, and that you haven't had any problems paying bills in the past.
If you and your partner don't have shared finance, then the normal rules apply and we can accept them as long as they meet our criteria.
A suitable guarantor is someone who is aged 19-75, has a good credit history, and can afford to make the monthly payments if you don't.
Your guarantor doesn't need to be a homeowner, but if they are, we're more likely to accept them.
