Guarantor Loans UK Guide (How They Work, Lender Options, Risks)

How Guarantor Loans Work

A guarantor loan works similarly to a standard unsecured personal loan, but with an additional person who acts as a guarantor. The borrower (you) takes out the loan and is primarily responsible for repayments. The guarantor signs a legally binding agreement promising to cover the payments if the borrower defaults. Most guarantor loans in the UK are offered by specialist lenders such as Amigo Loans, TrustTwo, Buddy Loans, and Guarantor My Loan. Loan amounts range from £500 to £10,000 (some lenders offer up to £15,000), with repayment terms from 1 to 7 years. The APR on guarantor loans is typically between 10% and 50% — significantly lower than payday loans but higher than standard personal loans. The interest rate depends on the borrower's credit profile and the guarantor's financial strength. The guarantor must be a UK resident aged 18–75 (or up to 80 depending on the lender), have a good credit history, be a homeowner or have a stable rental history, and have sufficient income to cover the loan payments if needed. The guarantor does not receive the loan funds — they only act as security. Their liability is usually for the full loan amount, including interest and late fees, not just the missed payment.

Risks for the Borrower

For the borrower, the main advantage of a guarantor loan is access to credit that would otherwise be unavailable. However, there are significant risks. Higher APR than standard loans — even with a guarantor, rates are typically 10–50% APR, compared to 3–15% for mainstream personal loans. Relationship strain — if you cannot repay, the pressure falls on your guarantor, which can damage personal relationships. Damage to credit score — missed payments appear on both your credit report and (in some cases) the guarantor's report. Default consequences — if you default, the lender can pursue you and the guarantor for repayment, potentially leading to CCJs, bailiff action, or attachment of earnings. Limited lending options — some guarantor lenders have less favourable terms, such as higher early repayment charges or compulsory insurance products. Debt collection practices — some lenders are more aggressive in pursuing guarantors than borrowers. Before taking a guarantor loan, consider whether you can realistically afford the repayments. If there is any doubt, discuss it honestly with your potential guarantor. They need to understand they could be asked to pay the full loan amount plus interest and fees.

Risks for the Guarantor

Being a guarantor is a serious financial commitment with legal consequences. The guarantor is jointly and severally liable for the full loan amount. If the borrower misses a payment, the lender can demand payment from the guarantor immediately — without first pursuing the borrower. Key risks for guarantors: full repayment liability — you could be asked to repay the entire outstanding loan, including interest, fees, and late payment charges. Credit score damage — if the borrower defaults and you do not pay, the lender may register a default or CCJ against you. Some lenders report the loan on your credit file, which can affect your ability to borrow for yourself. Strain on relationship — money issues can damage family and friendship ties. Limited future borrowing — the guarantor loan counts as a financial commitment against your name, which may reduce how much you can borrow for a mortgage or other credit. No benefit from the loan — the guarantor does not receive any of the loan funds but bears the full risk. The FCA requires lenders to ensure guarantors understand their obligations and to carry out credit checks and affordability assessments on guarantors. Guarantors have a 14-day cooling-off period. If you are asked to be a guarantor, seek independent legal or financial advice before signing. Never agree to be a guarantor for anyone unless you are fully prepared and able to repay the full loan amount.

Alternatives to Guarantor Loans

Before involving a guarantor, consider whether other options work for you. Bad credit loans (no guarantor) — some lenders offer unsecured loans for poor credit without requiring a guarantor, though rates are higher. See our Bad Credit Loans guide →. Credit union loans — capped at 42.6% APR, often with financial education and no guarantor required. Membership eligibility varies by location or employment. Secured loans — borrowing against your home or vehicle can provide lower rates, but your asset is at risk. See our Secured Loans guide →. Credit-building credit cards — if you need a smaller amount, a credit-builder card (Aqua Classic, Capital One Classic, Vanquis Visa) can improve your credit score over 6–12 months. See our Credit Score guide →. Short-term loans — for emergency borrowing under £1,000, see our Short Term Loans guide →. DWP budgeting loan — interest-free loan for people on certain benefits, available from the Department for Work and Pensions. Family loan (informal) — borrowing directly from family without a formal guarantor arrangement. Put a written agreement in place to avoid misunderstandings. Debt management plan — if your need to borrow stems from existing debt problems, a DMP may be more appropriate than taking on new debt.

How to Apply for a Guarantor Loan

The application process for a guarantor loan involves both the borrower and the guarantor. Step 1 — check your credit report for errors using free services (MSE Credit Club, ClearScore, Credit Karma). Step 2 — discuss the commitment with your potential guarantor. Ensure they understand they may have to repay the full loan amount plus interest and fees. Step 3 — use eligibility checkers on lender websites (soft searches) to check both your and your guarantor's likelihood of approval without affecting credit scores. Step 4 — compare loan offers across multiple lenders on total cost, APR, loan term, and early repayment options. Do not focus only on the monthly payment. Step 5 — submit a full application. The lender will perform credit checks on both borrower and guarantor (hard searches). Step 6 — if approved, both parties need to sign the loan agreement. The guarantor has a 14-day cooling-off period. Step 7 — the loan funds are paid to the borrower's bank account, typically within 1–3 working days. The guarantor never receives the funds. Throughout the loan term, the borrower should make timely payments to protect both their own and their guarantor's credit record and relationship.

FAQs

Can I get a guarantor loan without a homeowner guarantor?

Some lenders require the guarantor to be a homeowner, but others accept tenants with good credit history and sufficient income. Lenders like TrustTwo and Guarantor My Loan may accept non-homeowner guarantors if their financial profile is strong.

What happens if the borrower and guarantor both stop paying?

The lender can pursue both parties for repayment through debt collection, secure a CCJ against either or both, and enforce via bailiffs or attachment of earnings. Defaults remain on both credit files for 6 years, severely limiting future borrowing.

Can a guarantor withdraw after signing?

There is a 14-day cooling-off period during which the guarantor can cancel without penalty. After that, the guarantor cannot withdraw unless the loan is fully repaid or the lender agrees to release them (which most lenders will not).

Does a guarantor loan appear on the guarantor's credit file?

Some lenders report the loan on the guarantor's credit file as a financial commitment. This can affect the guarantor's ability to obtain other credit, such as a mortgage, because the loan reduces their affordability.

Are guarantor loans FCA-regulated?

Yes. Guarantor loans are regulated by the FCA under consumer credit rules. Lenders must conduct affordability checks, provide clear information, and treat customers fairly. Both borrower and guarantor have FCA protections and access to the Financial Ombudsman Service.
