What is a guarantor loan?
A guarantor loan is a type of personal loan where a second person (the guarantor) agrees to make the repayments if the borrower cannot. The guarantor is typically a family member or close friend with a good credit history and stable income. Their involvement reduces the lender's risk, which means borrowers with poor or limited credit can access loans they would otherwise be refused.
Guarantor loans are FCA-regulated and fall under the Consumer Credit Act 1974, which protects both the borrower and the guarantor. The lender must ensure the guarantor understands their obligations before the agreement is signed.
How does a guarantor loan work?
The borrower applies for the loan and nominates a guarantor. The lender assesses both parties: the borrower's ability to repay (income, expenses, existing debts) and the guarantor's creditworthiness and ability to cover the repayments if needed. If both pass the lender's checks, the loan is approved.
The borrower makes the monthly repayments as normal. The guarantor is only contacted if the borrower misses a payment. At that point, the guarantor becomes liable for the missed payment and potentially the remaining balance. Both the borrower's and the guarantor's credit files are affected by the loan — on-time payments help both credit scores, while missed payments damage both.
Who can be a guarantor?
Requirements vary between lenders, but most require a guarantor to meet the following criteria:
- Be aged between 21 and 75 (varies by lender)
- Have a good credit history with no recent defaults, CCJs, or IVAs
- Be a UK resident, usually a homeowner (though some lenders accept tenants)
- Have sufficient income to cover the loan repayments if needed
- Not be financially linked to the borrower (some lenders exclude spouses or partners)
What are the risks for the guarantor?
Being a guarantor is a serious financial commitment. If the borrower defaults, the guarantor becomes legally responsible for the entire remaining debt. This is not optional or negotiable — the guarantor signed a legally binding agreement. The specific risks include:
- Full liability: The guarantor is responsible for the full outstanding balance, not just missed payments
- Credit damage: If the borrower misses payments, this can affect the guarantor's credit score, even before the lender contacts the guarantor
- Reduced borrowing capacity: The guarantor loan may appear on the guarantor's credit file as a contingent liability, potentially reducing how much they can borrow for themselves
- Relationship strain: Financial obligations between friends or family members can damage relationships if things go wrong
What interest rates do guarantor loans charge?
Guarantor loan rates are typically between 25% and 50% APR. While this is higher than mainstream personal loans (which start around 3% APR for excellent credit), it is significantly lower than many alternatives available to borrowers with bad credit, such as payday loans or doorstep lending. The rate reflects the higher risk associated with lending to borrowers who have credit difficulties, even with a guarantor in place.
How much can you borrow with a guarantor loan?
Most guarantor loan lenders offer between £1,000 and £15,000, with repayment terms of 1 to 7 years. The amount you can borrow depends on both your income and your guarantor's financial position. Some lenders may offer higher amounts if the guarantor is a homeowner with substantial equity.
Alternatives to guarantor loans
Before committing to a guarantor loan, consider whether other options might be more suitable:
- Credit union loans: Credit unions often lend to people with poor credit at rates capped at 42.6% APR, without needing a guarantor
- Secured loans: If you own property, a secured loan may offer better rates than a guarantor loan
- Credit builder cards: If you do not need to borrow urgently, a credit builder card used responsibly can improve your score over 6-12 months, opening up cheaper borrowing options
- Specialist bad credit lenders: Some lenders now offer personal loans to borrowers with adverse credit without requiring a guarantor, at rates that may be comparable to guarantor loans
