A secured loan is one where you offer an asset, usually your home, as collateral. If you cannot repay, the lender can sell that asset to recover the money. An unsecured loan requires no collateral, so if you default the lender pursues you through the courts rather than seizing property. Secured loans offer lower interest rates and larger amounts; unsecured loans are safer for the borrower but cost more.
Short Summary
Secured loans in the UK are most commonly second-charge mortgages, where your home is used as security. Losing your home is a real possibility if you default, so this type of borrowing should only be considered when you are confident you can afford the repayments.
Unsecured personal loans from high-street lenders such as Barclays, HSBC, and Nationwide typically range from £1,000 to £25,000, with terms of one to seven years. Your interest rate depends primarily on your credit score.
The representative APR advertised by a lender is available to only 51 per cent of successful applicants. If your credit score is below average, you may be offered a higher rate. Always check your eligibility before applying to avoid unnecessary hard searches on your credit file.
For home improvement borrowing, a secured loan against your home may be appropriate if the project adds value. For everyday expenses, short-term borrowing, or consolidating smaller debts, an unsecured loan is generally the safer choice.
If you are considering a secured loan specifically to consolidate unsecured debts, get free advice from Citizens Advice or StepChange first. Turning unsecured debt into secured debt backed by your home increases your risk significantly.
What is a secured loan?
A secured loan is a loan backed by an asset you own, most commonly your property. The lender registers a legal charge against that asset, which gives them the right to sell it and recover the outstanding balance if you stop making repayments.
In the UK, secured loans on property are usually arranged as second-charge mortgages (separate from your main mortgage) and regulated by the FCA. The loan amounts available are typically larger than unsecured loans, often from £10,000 up to £100,000 or more, with repayment terms of up to 25 years.
What is an unsecured loan?
An unsecured loan does not require you to offer any asset as security. The lender assesses your creditworthiness using your credit report, income, and existing debts, and agrees to lend based on the risk of you not repaying.
If you default on an unsecured loan, the lender cannot automatically seize your property. They will pursue the debt through a County Court Judgement (CCJ), which can be enforced in various ways, including attachment of earnings. Your property is not at direct risk unless a court later orders a charging order against it, which is rare for smaller debts.
How do secured and unsecured loans compare?
| Feature | Secured loan | Unsecured loan |
|---|---|---|
| Asset required | Yes (usually your home) | No |
| Typical loan amount | £10,000 - £100,000+ | £1,000 - £25,000 |
| Typical term | 5 - 25 years | 1 - 7 years |
| Interest rate (APR) | Lower (often 5 - 15%) | Higher (often 6 - 40%+) |
| Risk to borrower | Home repossession if you default | CCJ; no direct asset risk |
| Credit score requirement | Moderate (asset reduces lender risk) | Higher credit score usually needed |
| FCA regulated | Yes | Yes |
When should I choose a secured loan?
A secured loan makes sense when you need a large amount (typically over £25,000), a long repayment term, and your credit score would make unsecured borrowing expensive or unavailable. Home improvement projects that add tangible value to your property are a common and reasonable use.
However, you must be certain you can sustain the repayments throughout the term. Job loss, illness, or a change in circumstances could put your home at risk. The longer the term, the greater the total interest paid, even at a lower rate. A £30,000 secured loan at 8 per cent over 15 years costs significantly more in total interest than the same loan at 12 per cent over five years.
When should I choose an unsecured loan?
An unsecured loan is appropriate for smaller amounts, shorter terms, and situations where you do not want to put your home at risk. Personal loans from Barclays, HSBC, Nationwide, and other high-street lenders are straightforward and regulated.
If you have a good credit score, you can access competitive rates on unsecured loans, often starting around 6 to 8 per cent APR for amounts between £7,500 and £15,000. Use a soft-search eligibility checker on MoneySavingExpert's loan eligibility calculator before applying, so you can see your likely rate without affecting your credit file.
Can I get a secured or unsecured loan with bad credit?
For secured loans, a lower credit score is less of a barrier because the lender holds your property as security. However, the interest rate you are offered will be higher to reflect the increased risk.
For unsecured loans, a poor credit history limits your options significantly. Mainstream lenders will likely decline your application. Specialist lenders such as Amigo Loans, Everyday Loans, and 118 118 Money serve borrowers with poor credit but charge considerably higher APRs, sometimes over 40 per cent. Consider whether the total cost of borrowing is worth it before proceeding.
FAQ
What happens if I cannot repay a secured loan?
If you miss repayments on a secured loan backed by your home, the lender will first attempt to contact you and offer a repayment arrangement. If arrears continue, they can apply to court for repossession. The FCA requires lenders to exhaust reasonable alternatives before seeking repossession, but the risk to your home is real if you do not engage with the lender early.
Is a mortgage a secured loan?
Yes. A mortgage is a form of secured loan where the property being purchased (or already owned) acts as collateral. If you default on your mortgage, the lender can repossess and sell your home to recover the outstanding balance.
Can I pay off a secured or unsecured loan early?
Yes, but check for early repayment charges. Under the Consumer Credit Act 1974, you have the legal right to repay any regulated loan early. Most lenders charge a fee, typically equivalent to one or two months' interest. For regulated mortgages (including second-charge mortgages), early repayment charges can be higher, particularly in the early years of a fixed-rate deal.
Will a personal loan affect my mortgage application?
Yes. A personal loan reduces your disposable income and increases your total debt, both of which affect the amount a mortgage lender will offer you. Avoid taking out unsecured loans shortly before a mortgage application. If you have existing personal loans, pay them down before applying where possible.
What is a guarantor loan and is it secured or unsecured?
A guarantor loan is a type of unsecured loan where a third party, usually a family member or close friend, agrees to repay the debt if you cannot. It does not require an asset as collateral, but the guarantor's credit score and finances are at risk if you default. Guarantor loans are typically used by borrowers with limited or poor credit histories.
