Guarantor Loans Explained: How They Work and What to Consider

If you've been offered a "guarantor loan" or seen one come up while comparing borrowing options, it's worth understanding exactly how they work before deciding whether one is right for you, for both you and whoever might act as your guarantor.

What is a guarantor loan?

A guarantor loan is a type of unsecured loan where a second person, the guarantor, agrees to make the repayments if you're unable to. Lenders sometimes offer these to applicants who might not qualify for a standard loan on their own, often because of a limited or poor credit history.

Who can be a guarantor?

Requirements vary by lender, but a guarantor is typically expected to:

• Be a UK resident, usually 21 or over
• Have a good personal credit history
• Have a stable income and pass their own affordability check
• Not be financially linked to you (e.g. not your partner, in some cases)

Many guarantor loan providers ask for a homeowner, though this isn't universal, so check the specific lender's criteria.

What does the guarantor actually agree to?

This is the part that's easy to underestimate. If you miss payments, the lender can and will ask your guarantor to cover them instead. This isn't a formality; it's a real financial and legal commitment. Before agreeing to be someone's guarantor, or asking someone to be yours, both sides should be genuinely comfortable with what happens if repayments are missed.

What are the risks?

• To the borrower: missed payments can damage your credit file, and defaulting can seriously affect your relationship with your guarantor.
• To the guarantor: you could be legally required to repay someone else's debt, and missed payments may also affect your own credit file, even though it isn't your loan.
• To both: guarantor loans often carry higher APRs than standard personal loans, reflecting the higher risk profile of applicants who need one.

Questions worth asking before you go ahead

• What happens, step by step, if a payment is missed?
• Is the guarantor's liability capped, or could it grow with added interest and fees?
• Can the guarantor be released from the agreement, and under what conditions?
• What is the total amount repayable over the full term, not just the monthly figure?

Is a guarantor loan the right choice?

It depends entirely on your circumstances. If you have someone willing and able to act as guarantor and you're confident in your ability to repay, it can be a way to access credit you might not otherwise qualify for. If you're unsure, it's worth exploring other options first.
