A HELOC is one way to access home equity, but it is not the only route and it is not the right fit for every borrower or every purpose. Depending on the amount needed, the timeline, whether revolving access matters, and the borrower’s appetite for securing debt against the property, one of the alternatives covered in this guide may be more appropriate, simpler, or cheaper.

This guide covers the six main alternatives to a HELOC available to UK homeowners: remortgaging, standard second charge mortgages, further advances from the existing lender, personal loans, credit cards, and equity release. Each section explains how the product works, when it suits, and when a HELOC may still be the better option. A comparison table at the end brings all the options together. The aim is not to argue for or against any particular product but to help the reader identify which route fits their specific circumstances.

Remortgage to release equity

Remortgaging means replacing the existing mortgage with a new, larger one and receiving the difference as cash. For example, a borrower with a £200,000 property and a £120,000 mortgage could remortgage to £160,000 and receive £40,000 (minus fees) to use as they choose. The new mortgage replaces the old one entirely.

The main advantage is the rate. First-charge mortgage rates are typically lower than second-charge rates (including HELOC rates), because the first-charge lender has priority in the event of repossession and therefore faces lower risk. Remortgaging also results in a single monthly payment rather than two separate payments (mortgage plus HELOC), which simplifies budgeting.

The main disadvantage is that the borrower loses their existing mortgage deal. If the current deal has a favourable rate that is still within its fixed or tracker period, remortgaging means giving it up and potentially paying early repayment charges on the existing mortgage. For borrowers on a competitive fixed rate with several years remaining, the cost of exiting the current deal can outweigh the benefit of the lower first-charge rate on the new mortgage. The process is also typically slower than a second charge application: a full remortgage involves a new mortgage application, a new valuation, new legal work, and a longer completion timeline. The guide to HELOC vs remortgage covers this comparison in detail.

Standard second charge mortgage

A standard second charge mortgage (also called a secured loan or homeowner loan) provides a lump sum secured alongside the existing mortgage. The existing mortgage remains untouched. The borrower makes separate monthly payments on the first-charge mortgage and the second-charge loan.

The main advantage over a HELOC is the wider lender market. The UK second charge mortgage market has many more providers than the HELOC market, which means more product variety, more competitive pricing, and more options for borrowers with adverse credit or complex circumstances. Fixed-rate products are widely available, giving payment certainty for the fixed period.

The main disadvantage compared with a HELOC is the loss of revolving access. The borrower receives the full lump sum at completion and the balance can only go down from there. If the full amount is not needed on day one (for example, for a phased home improvement project), a lump-sum loan charges interest on the full amount from completion, while a HELOC charges interest only on the amount drawn. For borrowers who need the full amount on day one, this distinction is irrelevant and a standard second charge is often the simpler route. The guide to home equity loan vs HELOC covers the full structural comparison.

Further advance from the existing lender

A further advance is additional borrowing arranged with the existing mortgage lender, added to the first-charge mortgage rather than taken as a separate second charge. The total mortgage balance increases, but everything remains on a single mortgage with a single lender. There is no second charge on the property.

The advantage is simplicity and cost. A further advance avoids the fees associated with second charge products (no separate product fee, arrangement fee, or broker fee for a second charge). The process may be faster because the lender already holds the mortgage and has existing information about the property and the borrower. The second charge vs further advance comparator can help assess which route is more cost-effective.

The disadvantage is availability and flexibility. Not all mortgage lenders offer further advances, and those that do may have restrictive criteria or offer less competitive rates than the open market. The rate on the further advance may be different from the rate on the existing mortgage, meaning the borrower has two different rates within the same mortgage. Eligibility is assessed against the lender’s current criteria, which may have changed since the original mortgage was arranged. If the lender’s criteria have tightened (for example, stricter affordability rules), the borrower may not qualify for a further advance even if they qualified for the original mortgage.

Personal loan

An unsecured personal loan provides a fixed amount (typically £1,000 to £25,000) at a fixed rate over a fixed term (typically one to seven years). The home is not used as security, which means there is no risk of repossession if repayments are not maintained (though the credit consequences of default are still serious).

The rate on a personal loan is higher than on secured lending products because the lender has no asset to recover if the borrower defaults. However, for smaller borrowing amounts, the total cost of a personal loan can be lower than a HELOC once the HELOC’s upfront fees (lender product fee, arrangement fee, and broker fee) are factored in. On a £10,000 borrowing requirement, for example, HELOC fees could total £1,500 to £2,500 or more before any interest is charged. A personal loan at a higher rate but with minimal fees may cost less overall for this amount.

Personal loans also avoid the complexity of a second charge, valuation, and legal work. The application process is simpler and faster. For borrowers who need a relatively small amount (under £15,000 to £20,000) and do not want to secure the debt against their property, a personal loan is worth considering as a straightforward alternative. The guide to alternatives to secured loans covers the unsecured options in more detail.

Credit card (0% or low rate)

For small borrowing amounts (under £5,000 to £10,000), a 0% purchase or balance transfer credit card can provide interest-free borrowing for a promotional period, typically twelve to twenty-four months. If the balance is cleared within the promotional period, the borrowing costs nothing in interest.

This suits specific use cases: paying for materials, furnishings, or smaller home improvement costs where the total amount is within the credit limit and the borrower is confident of clearing the balance before the promotional rate expires. It does not suit large projects, long-term borrowing, or borrowers who may not clear the balance in time, because the rate after the promotional period is typically 20% or above.

A credit card is not an alternative to a HELOC for significant borrowing. The credit limits are much lower, the post-promotional rates are much higher, and there is no structured repayment plan. But for the specific scenario of a small, short-term borrowing need, it can be the cheapest option available and avoids any form of secured lending.

Equity release (lifetime mortgage)

Equity release is a fundamentally different product category from a HELOC. A lifetime mortgage, which is the most common form of equity release, allows homeowners typically aged 55 or over to borrow against the property with no mandatory monthly repayments. Interest compounds over the borrower’s lifetime and is repaid (along with the original amount) from the proceeds of the property sale after the borrower dies or moves into long-term care.

The advantage for eligible borrowers is access to home equity without the burden of monthly repayments. Products compliant with the Equity Release Council include a no-negative-equity guarantee, meaning the borrower or their estate will never owe more than the property is worth. Some products allow voluntary repayments to control the interest accumulation.

The disadvantages are significant. Interest compounds over potentially decades, which can substantially reduce the estate value. The rates are typically higher than standard mortgage rates. And equity release reduces the inheritance available to beneficiaries. Equity release is a regulated advice area, and borrowers must use a qualified equity release adviser. It is not a substitute for a HELOC in most circumstances; it serves a different need (retirement income and flexibility) for a different demographic (older homeowners). The guide to HELOC vs equity release covers the detailed comparison.

Choosing between the options

The table below brings together all the main options for comparison. No single option is best for all borrowers. The right choice depends on the amount needed, the timeline, whether revolving access matters, the borrower’s existing mortgage position, and their appetite for securing the debt against the property.

The decision tree below works through the key questions in sequence. It is a simplified guide, not a recommendation, and the answer for any individual borrower will depend on their full circumstances.

Two rules of thumb emerge from this comparison. First, for smaller borrowing amounts (under £15,000 to £20,000), unsecured options (personal loan or credit card) are often simpler, cheaper overall once fees are considered, and avoid the risk of a second charge on the property. Second, for larger amounts where the full sum is needed on day one, a standard second charge mortgage is often more straightforward and more widely available than a HELOC. The HELOC’s distinctive advantage, paying interest only on the drawn balance and having revolving access during the draw period, is most valuable when the borrowing is phased, ongoing, or uncertain in total amount.

Frequently asked questions

Which alternative is cheapest?

It depends on the amount, the term, and the borrower’s circumstances. A remortgage often offers the lowest interest rate because first-charge rates are lower than second-charge rates, but the borrower may face ERCs on the existing mortgage and the process is slower. A personal loan avoids secured lending fees but carries a higher rate. For small amounts, a 0% credit card is cheapest if the balance is cleared within the promotional period.

The most reliable way to compare is to calculate the total cost (not just the monthly payment) for each option over the expected holding period, including all fees. The APRC captures the interest and lender fees for secured products but may not include broker fees, so those need to be added separately. For unsecured products, the APR is a more straightforward comparison metric.

Can I combine options?

Yes, and this can sometimes be the most practical approach. For example, a borrower who needs £50,000 in total could remortgage to release £40,000 (at the lowest rate) and take a personal loan for the remaining £10,000 (avoiding the need for a second charge). Or a borrower could use a HELOC for a phased home improvement project and a 0% credit card for furnishing costs. Each product is assessed independently, though the total monthly commitment across all borrowing is factored into each affordability assessment.

The main consideration when combining is the total cost across all the products and the total monthly commitment. Multiple borrowing arrangements mean multiple payments, multiple sets of terms, and multiple sets of fees. Keeping the structure as simple as practically possible reduces the risk of losing track of the overall position.

What if I have been declined for a HELOC?

The standard second charge mortgage market is larger and has more providers than the UK HELOC market, so a second charge mortgage may be available where a HELOC was not. This is particularly relevant for borrowers with adverse credit, where the wider lender market for second charge products includes more specialist providers. The guide to secured loans for bad credit covers the options.

For smaller amounts, a personal loan avoids the secured lending criteria entirely and may be accessible where a HELOC was not (though the rate will be higher). If the decline was due to an affordability issue rather than a credit issue, reducing the borrowing amount, clearing other debts to improve the affordability position, or waiting for income to improve may make a difference on a future application.

Is a HELOC always better than a personal loan?

Not for smaller amounts. The upfront fees on a HELOC (lender product fee, arrangement fee, and broker fee) can total several thousand pounds. For borrowing amounts under £15,000 to £20,000, these fees can make the total cost of a HELOC higher than a personal loan at a higher rate but with minimal fees, particularly over a shorter term. The break-even point, the amount at which the HELOC’s lower rate saves more than its higher fees cost, depends on the specific rate, fees, and holding period.

A personal loan also avoids the risk of a second charge on the property, which means the home is not at risk if repayments cannot be maintained. For borrowers who value this protection, or who are borrowing a relatively small amount for a short period, a personal loan may be the more appropriate choice even if the headline rate is higher. The guide to HELOC fees and costs covers the fee picture in full.

Can I switch from a HELOC to one of these alternatives later?

Yes. The HELOC products currently available in the UK do not carry early repayment charges, so the borrower can repay the HELOC in full at any time and replace it with a different product without incurring an exit penalty. The costs of switching are limited to the fees on the new product.

Common reasons for switching include: wanting to lock in a fixed rate after a period on a variable HELOC, consolidating the HELOC balance into a remortgage when the existing mortgage deal ends, or repaying the HELOC from the proceeds of a property sale or other windfall. The guide to refinancing a HELOC covers the options and costs involved in switching.
