What Is a Secured Loan? How They Work in the UK

What is a secured loan?

A secured loan is a type of borrowing where you use an asset — almost always your home — as security (collateral) for the debt. If you fail to keep up repayments, the lender has the legal right to repossess your property to recover the money owed. In the UK, secured loans are sometimes called homeowner loans, second charge mortgages, or simply second mortgages.

Unlike a personal loan, which is unsecured and based primarily on your income and credit score, a secured loan uses the equity in your property to back the debt. This typically means you can borrow larger amounts over longer terms and at lower interest rates than you would with unsecured borrowing.

How does a secured loan work?

When you take out a secured loan, the lender places a legal charge on your property. If you already have a mortgage, your mortgage lender holds the first charge. The secured loan lender holds a second charge — meaning they get repaid second if the property is ever sold or repossessed.

You receive the loan as a lump sum and repay it in fixed monthly instalments over an agreed term, which can range from 3 to 30 years depending on the lender and the amount borrowed. The interest rate can be fixed or variable.

How much can you borrow with a secured loan?

Secured loans in the UK typically range from £10,000 to £500,000, though some specialist lenders offer amounts up to £2 million. The amount you can borrow depends on several factors:

• Available equity — the difference between your property's current market value and your outstanding mortgage balance
• Loan-to-value (LTV) — most lenders cap the combined LTV (mortgage plus secured loan) at 80-90% of your property value
• Income and affordability — lenders must verify you can comfortably afford the repayments under FCA regulations
• Credit history — while secured loans are more accessible than unsecured borrowing for those with imperfect credit, your history still affects rates and maximum amounts

What can you use a secured loan for?

There are no restrictions on how you spend the funds from a secured loan. Common uses include:

• Home improvements — extensions, loft conversions, new kitchens, or structural work
• Debt consolidation — combining multiple debts into one lower monthly payment
• Large purchases — buying a vehicle, funding a wedding, or covering education costs
• Business purposes — using personal property equity to fund a business venture
• Raising a deposit — for a buy-to-let or second property purchase
• Tax bills — paying a large, unexpected HMRC liability

Secured loan vs remortgage: what is the difference?

Both secured loans and remortgages let you borrow against your property equity, but they work differently:

A remortgage replaces your existing mortgage with a new, larger one. You borrow more than your current balance and take the difference as cash. A secured loan sits alongside your existing mortgage as a separate debt.

A secured loan is often the better choice when you are locked into a good mortgage rate and would face early repayment charges (ERCs) for remortgaging, when you need funds quickly (secured loans typically complete faster), or when your credit situation has changed and you might not qualify for a competitive remortgage deal.

What are the advantages of secured loans?

• Borrow larger amounts — up to £500,000 or more, well beyond the £25,000-£50,000 cap on most unsecured loans
• Lower interest rates — typically cheaper than personal loans or credit cards because the lender's risk is reduced by the property security
• Longer repayment terms — spread over up to 30 years to keep monthly payments manageable
• Accessible with imperfect credit — the property security means lenders can be more flexible on credit history
• Keep your existing mortgage deal — no need to break a favourable fixed rate
• Faster than remortgaging — many secured loans complete in 2-4 weeks

What are the risks and disadvantages?

Other disadvantages include:

• Higher overall cost — longer terms mean you pay more interest over the life of the loan, even if the monthly payment is lower
• Arrangement fees — secured loans often carry broker fees, valuation fees, and legal costs that add to the total expense
• Early repayment charges — many secured loans carry ERCs if you repay early, particularly during an initial fixed-rate period
• Property valuation required — the lender needs to value your home, which adds time and cost
• Second charge implications — if you sell your property, the secured loan must be repaid in full alongside your mortgage

Who is eligible for a secured loan?

To qualify for a secured loan in the UK, you generally need to:

• Be a homeowner (or buying with a mortgage) with sufficient equity in your property
• Be aged 18 or over (some lenders have upper age limits of 70-85 at the end of the term)
• Have a regular income — employed, self-employed, or retired with pension income
• Pass the lender's affordability assessment, demonstrating you can comfortably manage the repayments alongside your existing financial commitments

Secured loans are available even if you have adverse credit, including CCJs, defaults, or a history of missed payments. Specialist lenders cater specifically to borrowers with imperfect credit, though rates will be higher.

How to apply for a secured loan

The application process typically involves:

1. Get advice from a broker — a specialist secured loan broker can search the whole market and find the best deal for your circumstances
2. Submit your application — providing details of your income, existing mortgage, property, and the purpose of the loan
3. Property valuation — the lender will arrange a valuation of your home (sometimes a desktop valuation, sometimes a physical survey)
4. Underwriting and approval — the lender reviews your application and makes a formal offer
5. Legal work — a solicitor handles the legal charge registration
6. Funds released — once everything is in order, the money is transferred to your account

The entire process typically takes 2-4 weeks from application to funds in your account, though this can vary depending on the lender and the complexity of your case.

Is a secured loan right for you?

A secured loan may be the right choice if you need to borrow a significant sum, want to keep your existing mortgage deal, or cannot access unsecured borrowing at a competitive rate. However, the risk to your home means you should always consider whether you can genuinely afford the repayments over the full term of the loan.

Speaking to a specialist secured loan broker is the best first step. They can assess your situation, compare deals across the whole market, and advise whether a secured loan is genuinely the most cost-effective option for your needs.
