Secured loans (second charge mortgages)

A secured loan, often called a second charge mortgage, is borrowing that’s secured against your property, but it sits behind your existing (first charge) mortgage. In practical terms, it’s a separate loan agreement with its own repayments, interest rate and term—without replacing your main mortgage.

This guide explains how second charge mortgages work, when they can be useful for homeowners, what to consider before proceeding, and the documents commonly required.

Who secured loans are for

Secured loans are typically considered by people who want to raise funds using the equity in their property while keeping their main mortgage in place.

They may suit:

• Homeowners with equity who want to access cash for a specific purpose
• People who are on a low fixed rate and don’t want to disturb it
• Borrowers who can’t remortgage easily (for example, due to early repayment charges, credit history changes, complex income, or affordability constraints)
• Self-employed borrowers, where income can be harder to evidence for mainstream mortgages
• Some landlords (including buy-to-let investors) where a second charge structure may be an option—subject to lender criteria

What a second charge mortgage is (and how it differs)

Your property can have more than one charge registered against it.

• Your first charge mortgage is the primary loan.
• A second charge mortgage is a separate secured loan, with the lender taking a second legal charge.

Because it’s separate, you generally continue paying your existing mortgage as normal, and you make additional repayments on the secured loan.

Common uses for secured loans

Second charge mortgages are often used for:

• Home improvements and renovations
• Debt consolidation (bringing multiple debts together into one repayment plan)
• Large one-off bills or planned expenses
• School fees, weddings, or other major costs
• Business-related needs (where the lender accepts the purpose)
• Cashflow support for some self-employed borrowers

How secured loans work (the typical journey)

While each lender has its own process, a second charge application usually involves the following stages:

1) Discuss your goals and borrowing needs

You’ll need to explain what you’re trying to achieve, how much you want to borrow, and how you plan to repay.

2) Lender assessment of equity, affordability and credit

Lenders will consider:

• Loan-to-value (LTV) based on the property value
• Affordability, including income and existing commitments
• Credit profile, including how you’ve managed credit historically

3) Property valuation

Depending on the lender and loan size, valuation may be:

• Desktop/automated valuation (often faster)
• A physical survey in certain cases

4) Consent and legal steps

Because your property already has a first charge, consent from the first mortgage lender is typically required. The second charge is then set up and registered.

5) Completion and drawdown

Once everything is agreed and the legal process is completed, the funds are released according to the lender’s process.

Secured loans vs remortgaging: when a second charge can be better

A second charge isn’t automatically the right choice for everyone. However, it can be attractive where:

• You want to keep your current mortgage rate (particularly if you’re on a low fixed rate)
• Early repayment charges (ERCs) or switching costs make remortgaging expensive
• You need access to equity without restructuring your main mortgage
• Your circumstances mean a mainstream remortgage may be harder (for example, affordability or credit considerations)

It’s also worth comparing alternatives such as product transfers (where available) or other ways to access funds, depending on your situation.

Costs to consider: looking beyond the headline rate

With any secured borrowing, the true cost depends on the full package—not just the interest rate.

When assessing a second charge, consider:

• Total cost of credit (including interest over the term)
• Fees (broker/advice fees, lender fees, valuation costs, and legal/registration costs)
• Whether fees are added to the loan or paid upfront
• How the cost changes if you settle early or make overpayments

A clear breakdown of all charges helps you compare options fairly.

Documents commonly requested

Second charge lenders typically require evidence to support affordability and identity. Common documents include:

• Photo ID and proof of address
• Mortgage statements for your existing first mortgage
• Details of income (for example, payslips for employees)
• For self-employed borrowers: SA302s and/or tax year overviews, plus relevant bank statements
• Information about debts if the purpose is debt consolidation (including any DMP arrangements, if applicable)

Exact requirements vary by lender and your circumstances.

Advantages of secured loans

A secured loan can offer benefits such as:

• Access to larger borrowing amounts than many unsecured options
• A structure that can be suitable where you want to avoid disturbing your main mortgage
• Potentially more flexibility for certain borrowers where mainstream mortgage criteria are harder to meet
• A way to release equity while keeping repayments on the first mortgage separate

Disadvantages and risks to understand

Second charge mortgages are secured against your property, so the risks are important to consider.

Key disadvantages include:

• If you can’t keep up with repayments, the lender may have the right to take action to recover the debt, which can include repossession
• Higher total interest if the loan is taken over a longer term
• The process can involve consent, valuation and legal steps, which can add time and cost

If you’re considering a second charge, it’s essential to ensure the repayments are genuinely affordable for the full term.

Secured loans vs unsecured loans

A secured loan is backed by your property, while an unsecured loan (such as a personal loan) is not.

Because secured borrowing reduces lender risk, it can sometimes offer:

• More borrowing capacity
• Different pricing structures compared with unsecured products

However, the trade-off is that secured loans carry property-backed risk.

Summary

A secured loan (second charge mortgage) is separate borrowing secured against your property behind your existing mortgage. It can be a useful way to access equity while keeping your main mortgage in place—particularly where remortgaging isn’t straightforward or would be costly.

Before choosing a second charge, it’s important to compare the full cost of credit, understand the documents and process, and make sure the repayments are sustainable.
