Can a family member be a guarantor on a business loan?

When a third-party guarantor works

Guarantees usually come from directors, but some lenders accept a third party — a family member — where the directors alone cannot support the borrowing, provided the guarantor has enough personal assets to make the guarantee meaningful. The lender will assess that person's financial position and creditworthiness just as they would a director's.

What it means for the guarantor

A guarantor takes on the same exposure a director would: if the company cannot repay, the lender can pursue them personally, up to any cap. That is a heavy commitment for someone with no control over the business. They should understand exactly what signing commits them to and take independent advice.

Handling it responsibly

Never pressure a relative into guaranteeing, and make sure they get independent legal advice — lenders often insist on it precisely to protect a non-director guarantor. Consider whether a no-guarantee route or company security avoids the need. Confirm the company can afford the loan on the affordability calculator so the guarantee is a backstop, not a plan.
