A secured loan is a form of borrowing where a property you own is used as security for the debt. The lender holds a legal charge against the property, meaning that if repayments are not maintained, the lender can pursue the property to recover what is owed. In exchange for this security, lenders typically offer lower interest rates and larger loan amounts than would be available on an unsecured basis, and over longer terms. For homeowners with equity in a property, a secured loan is often the most cost-effective way to borrow a substantial sum.
In formal and regulatory documentation, secured loans are referred to as second charge mortgages. The two terms describe the same product. Understanding what “second charge” means helps explain both how the product works and why it carries the risks it does. This guide covers the fundamentals: how secured loans are structured, when they make sense, what they cost, and what borrowers need to be aware of before applying.
At a Glance
- A secured loan uses your property as security: the lender holds a legal charge on it. The charge is registered at HM Land Registry, giving the lender a formal interest in the property that persists until the loan is repaid in full. If the borrower defaults, the lender can ultimately apply for repossession and sale of the property to recover the outstanding balance: what a secured loan is.
- The loan sits alongside an existing mortgage as a separate borrowing arrangement. Two separate monthly repayments run concurrently: one to the mortgage lender, one to the secured loan lender. The existing mortgage continues on its current terms and is not disturbed: how secured loans work.
- Rates and loan amounts depend on equity (LTV), income, and credit history. Rates typically range from around 5% to 18% or above. Fees including arrangement, valuation, and legal costs add 4% to 6% of the loan amount to the total cost. The term has a significant effect on total interest paid: what secured loans cost.
- Your property may be repossessed if repayments are not maintained. FCA regulation requires lenders to consider forbearance before taking enforcement action, but this does not eliminate the risk; it adds process. The repossession risk applies for the entire life of the loan: risks and benefits.
- The product is regulated by the FCA under the same rules as mortgages. Since March 2016, secured loans have been regulated as second charge mortgages with full affordability assessments, standardised documentation, and a mandatory seven-day reflection period between formal offer and completion: regulation and eligibility.
What Is a Secured Loan?
A secured loan is a loan where repayment is backed by a legal charge on a property. The charge is registered at HM Land Registry, giving the lender a formal interest in the property that persists until the loan is repaid in full. If the borrower defaults, the lender can ultimately apply for repossession and sale of the property to recover the outstanding balance. This legal security is what allows lenders to offer lower rates than unsecured products, larger loan amounts, and longer repayment terms.
Most secured loans in the consumer market are second charge mortgages: they sit behind an existing first charge mortgage rather than replacing it. The “second charge” describes where this lender ranks in the queue for repayment if the property is ever sold following a default. The first charge lender (typically the mortgage provider) is repaid first; the second charge lender receives whatever remains. This additional risk is why second charge mortgage rates are higher than first charge mortgage rates, even though both are secured on the same property. The second charge mortgage guide covers the legal charge structure and what it means in practice in more detail.
How a Secured Loan Works
When a secured loan is taken out, the lender carries out a property valuation to establish its current market value, assesses the borrower’s income and affordability, and reviews the credit history. The combined loan-to-value ratio, the total of the existing mortgage plus the new loan as a percentage of the property value, is the primary measure of security. Most lenders will lend up to 85% combined LTV, meaning the combined debt must not exceed 85% of what the property is worth.
Once the loan is approved, a second charge is registered at HM Land Registry, the funds are released, and repayments begin. The existing mortgage continues on its current terms; the secured loan sits alongside it, not in place of it. Two separate monthly repayments run concurrently: one to the mortgage lender, one to the secured loan lender. When the loan is fully repaid, the second charge is removed from the property title. For a step-by-step walkthrough of the application process, the how to apply guide covers each stage. For an explanation of how the LTV position works, the LTV ratios guide goes into detail.
Before the loan
One lender, one charge
The property has a single first charge registered against it, held by the mortgage lender. The borrower makes one monthly repayment. Any equity above the mortgage balance is unencumbered.
After the loan
Two lenders, two charges
A second charge is registered alongside the first. Two lenders each hold a legal interest in the property. Two monthly repayments run in parallel. The total secured debt is higher; the equity buffer is smaller.
What Secured Loans Are Used For
Secured loans are typically used when a borrower needs to raise a significant sum, more than an unsecured personal loan would provide or at a lower rate, and has sufficient equity in a property to support the borrowing. The following are the most common purposes in the UK market.
Home improvements
Extensions, conversions, kitchen and bathroom renovations, and energy efficiency upgrades are among the most common uses. Borrowing against the property for work that adds to its value is a natural application of secured finance.
Protecting a favourable mortgage rate
Borrowers who fixed their mortgage at low rates and want to raise capital without losing that rate will take a secured loan alongside the existing mortgage rather than remortgaging. This avoids repricing the entire mortgage balance at current market rates.
Debt consolidation
Combining multiple high-rate debts into a single secured loan can reduce monthly outgoings and total interest paid. This carries an important caveat: debts that were previously unsecured become secured against the property, which significantly raises the consequences of default.
Avoiding early repayment charges
Where an existing mortgage has a substantial early repayment charge, a secured loan raises capital without triggering it. The secured loan vs remortgage guide compares the total cost of each route in detail.
Business capital
Self-employed borrowers and small business owners sometimes use secured loans to fund business investment where business finance is unavailable or more expensive. The loan remains personal borrowing secured against a residential property.
Borrowers with adverse credit
Because the loan is secured against property, lenders can accept applicants with adverse credit histories who would be declined for unsecured borrowing. The security reduces the lender’s exposure, which is reflected in the rates offered. The secured loans for bad credit guide covers this in detail.
What Secured Loans Cost
The cost of a secured loan depends on three main variables: the loan amount, the interest rate (APR), and the term. The rate offered depends on the combined loan-to-value ratio, the borrower’s credit profile, and the lender’s own risk appetite. Rates in the second charge mortgage market typically range from around 5% to 18% or above, with lower LTV positions and cleaner credit histories attracting the more competitive end of the spectrum.
The term has a significant effect on both the monthly payment and the total interest paid. A shorter term means higher monthly payments but less total interest; a longer term reduces the monthly burden but increases the total cost substantially. The chart below illustrates how these trade-offs play out across different loan amounts and APRs. Figures are illustrative.

Beyond the headline rate, secured loans carry additional costs: arrangement fees (typically 1% to 2% of the loan), valuation fees, legal fees on both sides, and broker charges if a broker is used. Together these can add 4% to 6% of the loan amount to the total cost. The secured loan fees guide covers every fee type in detail, and the APR guide explains how rates are calculated and what they do and do not include.
Regulation and Eligibility
Secured loans (second charge mortgages) have been regulated by the FCA under full mortgage regulation since March 2016, following the implementation of the EU Mortgage Credit Directive. This means every lender and broker offering or arranging second charge mortgages must be FCA-authorised and must follow the same responsible lending rules that apply to first charge mortgage providers. These include a full affordability assessment, the provision of a standardised European Standardised Information Sheet (ESIS) before a binding offer is made, a mandatory seven-day reflection period between formal offer and completion, and regulated conduct if the borrower encounters financial difficulty.
Eligibility for a secured loan is assessed across several dimensions simultaneously. Lenders look at the equity in the property (the combined LTV position), the borrower’s income and affordability, their credit history, and the property type and condition. Unlike unsecured lending, where only the borrower’s creditworthiness matters, the property’s value and saleability are also part of the assessment because the lender’s security depends on being able to realise that value if repayment fails. The eligibility criteria guide explains in detail what lenders assess and what the thresholds look like in practice across each dimension.
Risks and Benefits
Secured loans offer genuine advantages over unsecured borrowing for the right borrower in the right situation. They also carry risks that are materially more serious than those associated with unsecured credit. Both sides of this picture need to be understood before any application is considered.
| Dimension | Potential benefit | Key risk |
|---|---|---|
| Property security | Enables lower rates and larger loan amounts than unsecured products would offer for the same borrower profile. | The property may be repossessed if repayments are not maintained. Lenders can and do pursue repossession following sustained default. |
| Rate and cost | For borrowers with equity and reasonable credit, rates are typically materially lower than unsecured personal loan rates for the same amount. | Rates are higher than first charge mortgage rates. Extending the term to lower monthly payments significantly increases the total interest cost. |
| Loan amount | Amounts of £10,000 to £250,000 or more are available, depending on equity, far beyond what most unsecured lenders will provide. | Taking on a large secured debt increases the total amount at risk if circumstances change. Over-borrowing relative to realistic income is a common cause of default. |
| Credit flexibility | The security of the property allows lenders to consider borrowers with adverse credit who would be declined for unsecured products. | Adverse credit borrowers typically face higher rates. Converting previously unsecured debt to a secured loan raises the stakes significantly if repayment becomes difficult. |
| Term flexibility | Terms of up to 25 years are available, providing flexibility in managing monthly cash flow. | Longer terms mean more total interest paid. A loan that looks affordable monthly may cost significantly more in total than a shorter-term alternative. |
| Credit file impact | Clean repayment history on a secured loan contributes positively to the credit file over time. | Missed payments carry negative markers that remain on the credit file for six years. A default can significantly restrict access to future credit. |
The most important risk is repossession, and it deserves clear framing. A secured loan uses the borrower’s home as security. This is not a formality; it is the legal mechanism that makes the product work. If repayments are not maintained, the lender has the right to pursue the property. FCA regulation requires lenders to consider forbearance before taking enforcement action, but this does not eliminate the risk; it adds process. The risks of secured loans guide and the what happens if you cannot repay guide cover the default and enforcement process in detail.
Secured Loans vs the Alternatives
A secured loan is not the right product in every situation where a borrower wants to raise money. Several alternatives are worth considering, each with different cost and risk characteristics.
A remortgage replaces the existing mortgage with a larger one, releasing equity as cash. It typically achieves a lower blended rate than a secured loan because the additional borrowing is at first charge rates, but breaking an existing mortgage deal may trigger a substantial early repayment charge, and the timing relative to the existing deal’s end date matters significantly. The secured loan vs remortgage guide covers this comparison in detail, including a calculator for comparing total costs.
An unsecured personal loan involves no property security and therefore no repossession risk. For amounts up to around £25,000 and borrowers with good credit, an unsecured loan may be competitive in rate terms and avoids putting the property at risk. For larger amounts or borrowers with impaired credit, the secured route typically offers materially lower rates and greater availability. The secured vs unsecured loans guide covers the decision framework for choosing between them.

What is the difference between a secured loan and a second charge mortgage?
There is no difference. They are two names for the same product. “Secured loan” is the consumer-facing term used in advertising and on comparison sites; “second charge mortgage” is the regulatory and legal term used in FCA documentation, HM Land Registry filings, and formal credit agreements. Since March 2016, both have referred to an identical product regulated under the same FCA mortgage rules that apply to first charge mortgages. The second charge mortgage guide explains the terminology, the legal charge structure, and what the regulatory change in 2016 meant for borrowers in detail.
The word “second” in second charge mortgage has a precise legal meaning: it describes the order in which the lender ranks for repayment if the property is ever sold following a default. The first charge lender, the mortgage provider, ranks first. The second charge lender ranks second, receiving only what remains after the first charge is satisfied in full. This hierarchy is why second charge rates are higher than first charge rates and why the equity buffer above the combined debt matters.
How much can I borrow with a secured loan?
The maximum available loan amount is determined by two independent constraints: the equity in the property (the combined LTV limit) and the affordability assessment (whether income is sufficient to service the repayments). Lenders typically lend up to 85% combined LTV, though the practical mainstream ceiling is closer to 80%. On a property worth £320,000 with a mortgage of £200,000, the maximum combined borrowing at 80% LTV would be £256,000, meaning up to £56,000 could be borrowed on a secured loan alongside the existing mortgage. The actual offer may be lower if the affordability assessment produces a smaller figure.
The LTV and equity calculator shows the equity position and maximum borrowing for a specific property value and mortgage balance. The eligibility checker provides a broader assessment that includes income and credit profile factors alongside the LTV position.
Can I get a secured loan with bad credit?
Yes, in many cases. Because the loan is secured against property, lenders can accept borrowers with adverse credit histories, including missed payments, defaults, CCJs, and in some cases discharged bankruptcy, where an unsecured lender would decline. The security of the property reduces the lender’s exposure, which is what allows this broader acceptance. The trade-off is that adverse credit typically results in a higher rate and a more restricted choice of lenders. The severity, recency, and whether adverse markers are satisfied or outstanding all affect what is available and at what rate.
For borrowers with adverse credit, using a soft-search eligibility check before submitting a formal application is particularly important: it gives an indication of likely acceptance and rate without leaving a hard search on the credit file. Multiple formal applications that are then declined add negative markers and compound the difficulty. The secured loans for bad credit guide covers the adverse credit landscape and the lender market in detail.
How long does a secured loan take to arrange?
A typical secured loan takes four to eight weeks from formal application to funds received. The process involves a property valuation, full underwriting, legal work to register the second charge at HM Land Registry, and a mandatory seven-day reflection period between formal offer and completion. Cases where an automated valuation is used rather than a physical inspection, and where documentation is complete at the point of application, tend to progress at the faster end of this range. Cases with non-standard properties, complex income situations, or solicitor delays run towards the upper end.
The process is not sequential: the valuation, underwriting, and legal tracks run simultaneously from around day ten, and the total timeline is determined by whichever track takes the longest. The how long a secured loan takes guide covers each stage, why they can stall, and the practical steps that most reliably keep the process on schedule.
Squaring Up
A secured loan is a way of borrowing a significant sum against property equity. The legal charge the lender holds is what makes the lower rates and larger amounts possible, and it is also what makes this a more serious commitment than unsecured borrowing. Both the property valuation and the affordability assessment must satisfy the lender before the loan can proceed. The rate offered depends primarily on the combined LTV position and the borrower’s credit profile. Fees add materially to the total cost and must be factored into any genuine cost comparison. The fundamental risk, that the property may be repossessed if repayments are not sustained, applies for the entire life of the loan and needs to be the starting point for any decision about whether to proceed.
