Guarantor Loans in the UK: What to Know Before You Borrow

Updated July 2025

Guarantor loans are often marketed as a solution for people with bad credit or no credit history. They can provide access to borrowing when other lenders refuse, but they also place a significant legal and financial burden on the person who agrees to guarantee the loan. In the UK, these products have grown in popularity due to stricter lending rules and rising living costs, but that has also led to more cases of financial strain for both borrowers and guarantors. Understanding exactly how they work, the potential risks, and the safer alternatives available is essential before you commit.

What Is a Guarantor Loan?

A guarantor loan is a type of unsecured personal loan where someone else, typically a friend or family member, agrees to repay the debt if you do not. The loan approval is based largely on the guarantor’s creditworthiness rather than your own credit record.

How It Works:

Who Can Be a Guarantor?

Most lenders require guarantors to meet specific criteria, such as:

For example, a parent who owns their home outright and has a long history of on-time mortgage payments is likely to be accepted. However, if the guarantor has existing debts or a limited income, they could struggle to meet repayments if you default.

What Are the Risks?

Guarantor loans are high-risk for both borrowers and guarantors.

Frequently Asked Questions

Can a guarantor withdraw after signing?

Once the loan agreement is signed and funds are released, the guarantor generally cannot withdraw. They are legally bound to the terms until the loan is repaid in full.

Do guarantor loans improve my credit score?

Yes, if you make repayments on time. However, missed payments will harm your score and could also impact your guarantor's credit record.

Can the lender take the guarantor to court?

Yes. If the borrower defaults and the guarantor fails to pay, the lender can take legal action against the guarantor to recover the debt.

Is there a cooling-off period?

In most cases, there is a 14-day cooling-off period under UK consumer credit law, allowing either party to cancel before funds are drawn.

Final Thoughts

Guarantor loans can be a lifeline for those with limited borrowing options, but they are not a decision to take lightly. The financial and personal consequences can be long-lasting for both borrower and guarantor. Always review safer alternatives first and ensure both parties fully understand the commitment.
