If you have been reading US personal-finance advice, you may have come across the term “home equity loan” and wondered what the UK equivalent is. The closest match is usually a second charge mortgage, but it is not the only way a UK homeowner can release money tied up in a property. Depending on your existing mortgage, the amount you want to borrow and the costs involved, a further advance or a remortgage may be more suitable.
The key point is that UK home equity borrowing is normally discussed in mortgage terms rather than under a single product called a home equity loan. Your equity is the portion of your property you effectively own: the current market value minus any mortgage debt secured against it. Having equity does not automatically mean you can borrow all of it, because lenders also look at affordability, credit history, property value and loan-to-value limits.
The closest UK equivalent: a second charge mortgage
A US home equity loan is typically a separate lump-sum loan secured against a homeowner’s property while the original mortgage remains in place. In the UK, a second charge mortgage works in a similar way. You keep your existing first mortgage and take an additional secured loan against the same property.
The “second charge” name refers to the order in which lenders have a claim over the property. If the home is sold or repossessed, the first mortgage lender is repaid before the second charge lender. Because the second lender takes more risk, rates can be higher than on a first-charge mortgage. As with other borrowing secured on your home, missed repayments can ultimately put the property at risk.
A second charge mortgage can be worth considering when your existing mortgage has an attractive rate that you do not want to give up, or when remortgaging would trigger a large early repayment charge. It may also be considered when the amount required is substantial enough that an unsecured personal loan is not practical.
How a further advance differs
A further advance means borrowing extra money from your current mortgage lender. Rather than taking a separate secured loan from another provider, you ask your existing lender to increase your borrowing. The additional amount may be placed on a different interest rate or product from your original mortgage.
This can be a relatively straightforward option if your lender offers competitive terms and you have enough equity and income to pass its affordability checks. It is commonly used for major home improvements, but lenders may allow other purposes subject to their criteria.
Do not assume a further advance will automatically be the cheapest choice. Compare the interest rate, arrangement fees, repayment term and total amount repayable with the alternatives. Extending a relatively modest amount over a long mortgage term can make the monthly payment look manageable while increasing the total interest paid.
Remortgaging to release equity
Another route is to replace your existing mortgage with a new, larger mortgage and take the difference as cash. This is often described as remortgaging to release equity. For example, you might owe £180,000 on your current mortgage and arrange a new mortgage for £220,000, with the additional borrowing used for an approved purpose after fees and any existing balance are settled.
Remortgaging can make sense if you are already near the end of your current deal, can obtain a competitive new rate and want to combine your borrowing into one mortgage. However, the headline rate is only part of the calculation. Valuation fees, product fees, legal costs and early repayment charges can change the result significantly.
If your current mortgage is on a particularly low fixed rate, replacing the whole balance with a higher-rate mortgage simply to raise a smaller amount of cash may be poor value. In that situation, comparing a further advance and a second charge mortgage becomes especially useful.
A practical example of how equity affects borrowing
Suppose your home is worth £350,000 and your outstanding mortgage is £210,000. On paper, you have £140,000 of equity. That does not mean a lender will let you withdraw £140,000.
If a lender were willing to lend up to 80% of the property value, the maximum total secured borrowing under that particular limit would be £280,000. With £210,000 already outstanding, there would be £70,000 of theoretical headroom before considering affordability, fees and the lender’s individual rules. A lender could still offer less, or decline the application entirely, after assessing your income, expenditure, credit record and the reason for borrowing.
This is why “how much equity do I have?” and “how much can I borrow?” are different questions. The first is mainly a property-value calculation; the second is a lending decision.
Is there a UK equivalent of a HELOC?
A home equity line of credit, or HELOC, is another common US product. It usually provides a revolving credit facility secured against the home, allowing the borrower to draw, repay and draw again up to an agreed limit.
The UK mortgage market does not have a single widely used mainstream product that maps neatly onto the typical US HELOC. Some flexible or offset mortgage arrangements can offer features that allow overpayments to be redrawn, but the rules vary and they should not be treated as direct HELOC equivalents. If flexibility is the main goal, check exactly how withdrawals, overpayments, interest and limits work before relying on a product description.
What should you compare before choosing?
Start with the total cost rather than the size of the monthly payment. A second charge mortgage, further advance and remortgage can all spread borrowing over many years, which may reduce monthly payments while increasing total interest.
Also check whether your current mortgage has an early repayment charge, whether a new deal would move your whole balance onto a different rate, and how much each option costs in fees. Think carefully before turning short-term spending or unsecured debts into borrowing secured against your home, because doing so can extend the repayment period and increase the consequences of falling behind.
For a meaningful comparison, ask for figures based on the same borrowing amount and similar repayment periods. That makes it easier to compare the true cost rather than choosing whichever option produces the lowest monthly figure.
Frequently asked questions
What is a home equity loan called in the UK?
The closest UK product is generally a second charge mortgage, which is a separate loan secured against your home while your original mortgage remains in place. A further advance or remortgage may achieve a similar goal in a different way.
Can I borrow against the equity in my UK home?
Potentially, yes. Lenders may allow additional borrowing if you have sufficient equity and meet their affordability, credit and property criteria. Available equity alone does not guarantee approval.
Is a second charge mortgage the same as remortgaging?
No. A second charge mortgage sits alongside your existing mortgage. Remortgaging replaces the existing mortgage with a new mortgage, which can sometimes be larger so that part of the equity is released as cash.
Which option is usually cheapest?
There is no universal cheapest option. The answer depends on your existing mortgage rate, early repayment charges, new interest rates, fees, borrowing term and personal circumstances. Comparing total repayment costs across the same time period gives a clearer picture.
Choosing the right UK route
For most people searching for a home equity loan UK equivalent, the useful comparison is not between identical products, because there is no exact one-to-one match. It is between three practical routes: keeping the first mortgage and adding a second charge mortgage, borrowing more from the existing lender through a further advance, or replacing the mortgage and releasing equity through remortgaging.
The best fit depends on what you already owe, the rate you are paying, how much you need and how long you expect to keep the borrowing. Before securing extra debt against your home, compare the full cost and consider regulated mortgage advice if you are unsure which structure suits your circumstances.
