Home equity loans in the UK: equity and secured borrowing explained

Key considerations

What is home equity?

Home equity is broadly the current value of a property minus the mortgage and any other loans already secured against it. It represents the homeowner's financial interest in the property at a particular point in time, before allowing for selling costs or changes in value.

For example, if a home were valued at £300,000 and the mortgage plus any other secured borrowing totalled £180,000, the estimated equity would be £120,000. This is a simple illustration, not a valuation, loan offer or amount that could automatically be borrowed.

Equity can increase when secured balances are repaid or the property rises in value. It can fall if further borrowing is secured on the home or the property's value decreases. Because both values can change, an equity calculation is always a snapshot.

How can you estimate the equity in your home?

Start with a realistic estimate of the property's current market value. Recent comparable sales, a local estate agent's opinion or a professional valuation may provide context, but a lender can use its own valuation method and may reach a different figure.

Then obtain current balances for the first mortgage and every other loan or legal charge secured against the property. Subtract the total secured balances from the estimated property value. Do not use the original mortgage amount or an outdated statement, because repayments and added borrowing can change the balance.

The result does not allow for possible early-repayment charges, sale costs or other liabilities. It is useful for an initial conversation, but the lender's valuation and criteria will be more relevant to any application.

What does loan-to-value mean?

Loan-to-value, usually shortened to LTV, compares borrowing secured against a property with the property's value. If total secured borrowing were £180,000 on a property valued at £300,000, the combined LTV would be 60%. The remaining 40% would represent estimated equity before other costs.

For a second-charge application, a lender may consider the combined LTV after including the proposed new loan. A lower property valuation or higher mortgage balance would increase that percentage and reduce the apparent equity. Lenders set their own maximums and other criteria, so the calculation does not predict acceptance or terms.

LTV describes the security position; it does not show whether monthly repayments are affordable. A homeowner can have substantial equity and still be unable to support further borrowing from income after normal expenditure and existing commitments.

What is a home equity loan in the UK?

“Home equity loan” is used more commonly in some overseas markets than as a formal UK product name. In the UK, people using the term often mean a secured homeowner loan, second-charge mortgage or second mortgage: a separate loan secured against a property that already has a first mortgage.

A second-charge loan normally provides a lump sum and is repaid through monthly instalments over an agreed term. The first mortgage stays in place, and the homeowner makes a separate payment for the new agreement. Both lenders hold legal charges over the same property.

The word “second” describes the usual priority of the legal charge, not a replacement for the original mortgage. If the property were sold after repossession, the first-charge lender would normally be repaid before the second-charge lender. A remaining shortfall can still be owed by the borrower.

Does having equity mean you can borrow against it?

No. Owning a home or having estimated equity does not guarantee approval. A lender may assess the property, current secured borrowing, requested amount and purpose as well as income, expenditure, existing commitments, credit information and foreseeable changes in circumstances.

For regulated mortgage borrowing, affordability cannot be based only on the equity in the property or an expectation that house prices will rise. The proposed payment needs to appear sustainable alongside the first mortgage, essential household spending and other credit commitments.

The amount that might be available, if any, can therefore be much lower than the headline equity figure. Treat equity as one part of the assessment rather than a spending budget or entitlement to credit.

Why might someone consider a second-charge loan?

A homeowner may consider a second charge when they need to fund a defined purpose and want to leave the existing first mortgage in place. This may be relevant where replacing the first mortgage could mean losing its current rate or paying an early-repayment charge.

Possible purposes can include planned home improvements or consolidating eligible debts. The purpose being permitted does not make secured borrowing automatically suitable. The amount, useful life of the expense, repayment term, full cost and lower-risk alternatives should all be considered.

Debt consolidation needs particular care because it can turn credit cards or personal loans into debt secured against the home. A lower monthly payment achieved through a longer term can also increase the total amount repaid, and repaid credit accounts can be used again unless the cause of the balances is addressed.

Second charge, further advance or remortgage?

A second-charge loan is a separate agreement from a new lender or lending arrangement and normally sits alongside the existing mortgage. A further advance is additional borrowing from the current mortgage lender, potentially with its own rate and terms. Remortgaging replaces the existing mortgage with a new mortgage and can include extra borrowing.

A remortgage can change the rate applied to the whole mortgage balance and may involve arrangement, valuation or legal costs plus an early-repayment charge on the current deal. A further advance leaves the existing mortgage in place but adds borrowing through the same lender. A second charge also leaves the first mortgage in place but creates a separate legal charge and payment.

None of these routes is always cheapest. Compare the rate, APRC, fees, term, monthly payment, total amount repayable and early-settlement conditions for each realistic option. Include the combined cost of every mortgage and secured loan that would remain after completion.

How much can a home equity loan cost?

The cost depends on the amount, interest rate, fees and repayment term. The offered rate may reflect the property and combined LTV as well as affordability, credit information, the loan request and the lender's criteria. Bank Rate provides economic context but is not the rate an individual borrower receives.

A longer repayment term can reduce the monthly amount but allow interest to build over more years. Fees added to the balance may also attract interest. Compare the APRC and total amount repayable rather than focusing only on the headline rate or whether the payment is lower than another option.

Check whether the rate is fixed or variable, when it can change, whether overpayments are allowed and whether early-repayment charges apply. Read the personalised illustration and offer carefully before deciding.

What are the risks of borrowing against home equity?

A secured loan places a legal charge on the property. If repayments are not maintained, the home may ultimately be repossessed. The risk needs to be considered across both the first mortgage and new loan, because the household remains responsible for both payments.

Using equity reduces the financial cushion between the property's value and the total secured borrowing. If the home later falls in value, selling or refinancing may become more difficult. The repayment plan should not rely on future house-price growth or assume another loan will be available later.

Test whether payments would remain manageable if income fell, essential costs rose or a variable rate increased. Consider how long the commitment lasts and whether it extends into retirement or beyond the useful life of what the money funds.

Is a home equity loan the same as equity release?

No. In everyday speech, “releasing equity” can mean raising money against a property. In the regulated UK market, “equity release” normally refers to specialist later-life products: lifetime mortgages and home reversion plans. These are different from a standard second-charge repayment loan.

A lifetime mortgage is generally repaid when the last borrower dies or moves permanently into long-term care. If interest is not paid, it can be added to the loan and compound over time. A home reversion plan involves selling all or part of the property to a provider under the plan's terms.

Later-life equity release can affect inheritance, means-tested benefits, care plans, moving home and future financial choices. Specialist advice is required. Homeowners who can make monthly payments may have other options, but those alternatives have their own affordability requirements, costs and property risks.

What should you check before borrowing against your home?

Start with the amount genuinely needed and the purpose it will serve. Gather accurate property, mortgage and household information, compare property-backed borrowing with unsecured and non-borrowing alternatives, and take time to understand the full commitment.

• Estimate the current property value using realistic evidence.
• Obtain up-to-date balances for every mortgage and secured loan.
• Calculate estimated equity and the current and proposed combined LTV.
• Do not treat the equity figure as a guaranteed borrowing limit.
• Compare a second charge with a further advance, remortgage and relevant unsecured options.
• Review the interest rate, APRC, fees, term, monthly payment and total amount repayable.
• Check whether fees are added to the loan and charged interest.
• Understand the rate type, overpayment rules and early-repayment charges.
• Test affordability if income, household costs or interest rates change.
• Clarify whether a product is a repayment loan or specialist later-life equity release.
• Remember that missed payments on secured borrowing can put the property at risk.
