Mortgages
A debt consolidation remortgage lets you combine existing debts, such as credit cards or personal loans, into your mortgage as a single monthly payment. Here's how it works, the risks involved, and how to work out if it suits your circumstances.
A debt consolidation remortgage is when you replace your existing mortgage with a new, larger one and use the extra borrowing to pay off other debts, such as credit cards, personal loans, or overdrafts. Instead of managing several separate payments, you're left with a single monthly mortgage payment.
This works because mortgage interest rates are typically much lower than the rates charged on unsecured borrowing. However, spreading the debt over a much longer mortgage term usually means paying more interest overall, even where the rate is lower.
Whether a debt consolidation remortgage makes sense depends on your total debt, your equity, your income, and how quickly you'd otherwise clear the debt. Speak to an advisor to work through the numbers for your own situation.
A debt consolidation remortgage involves replacing your existing mortgage with a new, larger one. The extra borrowing covers the value of your outstanding debts, which are then paid off in full. Instead of managing multiple creditors with different interest rates and payment dates, you're left with a single mortgage payment each month.
This works because mortgage interest rates are typically much lower than other forms of borrowing, such as credit cards, personal loans, or overdrafts. That gap is why debt consolidation remortgages remain one of the most common reasons people remortgage, but it isn't a decision to take lightly. You're converting unsecured debt into debt secured against your home, so your property is at risk if you can't keep up with the new, larger mortgage payment.
When you remortgage to consolidate debt, your new lender pays off your existing mortgage balance and provides the additional funds needed to clear your other debts. You can either use the funds yourself to pay off your creditors, or in some cases, the lender or your broker will pay creditors directly on your behalf.
For example, if you owe £150,000 on your current mortgage and have £30,000 in credit card and loan debt, you'd be looking at a new mortgage of around £180,000. Your existing creditors get paid in full, and you're left with one monthly payment to your new mortgage lender.
To be eligible for a debt consolidation remortgage, you need enough equity in your home. Equity is the portion of your property's value that you own outright, calculated by subtracting your mortgage balance from your property's market value.
If your home is worth £300,000 and you owe £150,000, you have £150,000 in equity. Most lenders will let you borrow up to around 80-90% of your property's value (loan-to-value, or LTV) through a remortgage, though this depends on the lender's criteria and your individual circumstances. The best terms are typically reserved for those borrowing 60% or less of the property's value.
This is the part to understand properly before you go ahead. When you consolidate debts into your mortgage, you're converting unsecured debt into secured debt. Credit cards and personal loans are usually unsecured, meaning that while there are consequences for not paying them, your home isn't directly at risk.
Once those debts become part of your mortgage, they're secured against your property. Missing payments on secured debt can put your home at risk of repossession, and it also reduces the equity you hold. This is the single most important consideration when deciding whether a debt consolidation remortgage is right for you.
The interest rate on a debt consolidation remortgage is usually much lower than a credit card or personal loan, but you'll often repay over a far longer term. Before deciding, ask your advisor to show you the total amount repayable, not just the change in your monthly outgoings.
Not sure where to start?
Every situation is different. Speak to an advisor who can look at your debts, your equity, and your income before you make a decision.
Understanding the potential benefits helps you weigh up whether consolidation could work for your circumstances.
The most immediate benefit is often a reduction in your monthly outgoings. This happens for two reasons: lower interest rates and a longer repayment term. Replacing high-interest debts like credit cards with borrowing at a mortgage rate, spread over a longer term, can free up a meaningful amount of cash each month.
Managing multiple debts means multiple due dates, interest rates, and creditors to keep track of. For many people, this mental load is as challenging as the financial burden itself. After consolidating, you have one payment, one due date, and one statement to track, which can make budgeting more manageable.
Credit card debt, particularly when you're using a high proportion of your available credit, can affect your credit score. Paying off credit cards through a remortgage reduces your credit utilisation, which often improves your score over time. This can help you access better terms in future, whether for a mortgage or other borrowing.
If you consolidate onto a fixed-rate mortgage, you'll know exactly what you're paying for the duration of the fix. This protects you from interest rate rises during that period and can make long-term budgeting easier.
It's just as important to understand the downsides as the benefits. A debt consolidation remortgage isn't right for everyone, and overlooking the risks could lead to serious financial problems.
This is the most significant financial drawback. While your monthly payment usually drops, you'll typically repay over a much longer period, often 15-25 years, instead of the 3-5 years typical of a personal loan or the shorter effective repayment period of credit card debt. Spreading debt over a mortgage term can mean paying more interest overall, even though the rate is lower.
The real comparison depends on how you'd realistically repay the debt without consolidating. If you'd otherwise only make minimum payments for years, consolidation might save you money overall. If you could clear the debt quickly through focused effort, consolidation often costs more in total interest.
This can't be stated strongly enough. Your home may be repossessed if you do not keep up repayments on your mortgage or any other debt secured on it. Credit card companies can pursue you for unpaid debt and damage your credit score, but they can't take your home directly. Once debt is secured against your property, that protection disappears.
This is particularly important if your financial difficulties stem from unstable income or circumstances likely to continue. Consolidating might ease pressure in the short term, but if you can't sustain the new payments, you risk losing your home.
Adding debt to your mortgage increases your loan-to-value ratio. If this pushes you into a higher LTV bracket, you'll likely face less competitive terms than you would at a lower LTV.
If your current mortgage has an early repayment charge, you'll need to factor this into your decision. These charges can be significant in the early years of a fixed deal and may outweigh any short-term benefit from consolidating. It's worth checking your mortgage offer or speaking to an advisor about whether waiting until your fixed period ends makes more sense.
Remortgaging isn't free. You'll typically encounter valuation fees, legal or conveyancing fees, and sometimes an arrangement fee, alongside any early repayment charge on your existing mortgage. Some credit cards and loans also charge early settlement fees. These costs need to be weighed against the potential benefit of consolidating.
If your current mortgage deal has an early repayment charge, it's often worth checking whether waiting until the fixed term ends makes more financial sense than consolidating straight away.
It's worth assessing your personal circumstances carefully before deciding whether a debt consolidation remortgage is right for you. Adding debt onto your mortgage can affect your finances for years to come and will reduce the equity in your property, so it deserves proper thought rather than a quick decision.
Weighing it up
You have substantial high-interest debt
If you're paying a high rate of interest on £15,000 or more of unsecured debt, the rate reduction from consolidating can be significant enough to justify the approach.
Your current mortgage deal is ending
If you're about to move onto your lender's standard variable rate anyway, you're already looking at remortgaging. Adding debt consolidation at this point can minimise disruption and extra cost.
You're struggling with monthly cash flow
If multiple debt payments are making day-to-day finances unmanageable, the breathing room from consolidation can help prevent worse outcomes like missed payments and damaged credit.
You have sufficient equity
If consolidating keeps your loan-to-value below around 80%, you'll likely still access competitive terms. Those with more equity are in the strongest position.
Your financial situation is otherwise stable
If you have reliable income and the main challenge is managing multiple payments rather than fundamental affordability, consolidation can work well.
Weighing it up
Do the maths
A simple framework for working through the numbers before you decide.
Total your current debts
List every debt you're considering consolidating, along with the balance and current monthly payment for each. This gives you a clear starting point for comparison.
Understand your current mortgage position
Work out your current mortgage balance, your property's approximate value, and your current loan-to-value ratio. This tells you how much equity you have to work with.
Calculate your post-consolidation position
Add your existing mortgage balance to the debt you want to consolidate to see your new borrowing requirement, and work out what LTV bracket this places you in. Moving into a higher bracket can affect the terms available to you.
Compare the total costs
Ask your advisor for illustrations that show the total amount repayable under each option, not just the change in your monthly outgoings. Compare this against a realistic estimate of what you'd pay if you kept your debts separate, including all fees and any early repayment charges.
Consider the wider picture
Numbers don't capture everything. Think about the reduced stress of simpler finances, the risk of having more debt secured against your home, and whether you'd realistically pay off the debts quickly without consolidating.
If your situation is complex, such as multiple debts or a less straightforward credit history, a specialist lender may be needed. Specialist lenders often work through mortgage brokers and can help in cases where standard lenders won't. Here's what lenders look at when assessing an application.
Under Financial Conduct Authority rules, lenders must assess whether you can afford the new mortgage repayments. They'll look at your income, existing commitments, and essential expenditure, including:
Lenders also stress-test your application, checking you could still afford the payments if interest rates rose.
Your credit history matters more with debt consolidation, because lenders can already see that you've accumulated debt. They'll look at recent late payments or defaults, your credit utilisation, the length of your credit history, and recent credit applications. You don't need perfect credit to consolidate debt through remortgaging, but more serious credit issues will limit your options and likely mean less competitive terms. Some specialist lenders focus on borrowers with imperfect credit, though this comes at a cost.
Most mainstream lenders cap debt consolidation remortgages at 80-85% loan-to-value. Some will go higher, but options become more limited above that. The lower your LTV, the more lenders will compete for your business and the better the terms you're likely to access.
Your property serves as security for the loan, so lenders need to be confident in its value and saleability. Standard properties in good condition present no issues. Complications can arise with non-standard construction, properties requiring significant repair, flats in certain buildings, properties with short remaining leases, or very high or low value properties.
You'll need to prove your income. Employed applicants typically provide recent payslips, a P60, and sometimes an employment contract. Self-employed applicants usually need two to three years of accounts or tax calculations, plus tax year overviews. Lenders want to see stable income that comfortably supports the new mortgage payment.
How it works
Most debt consolidation remortgages complete within four to eight weeks, from initial enquiry to completion.
Initial assessment
Get an accurate property valuation estimate, total the debts you want to consolidate, check your credit report, and calculate your current and post-consolidation loan-to-value. A broker can run initial affordability checks at this stage.
Finding the right deal
Your advisor searches for suitable products, weighing up the rate bracket for your LTV, fixed vs variable options, term length, arrangement fees, and each lender's attitude to debt consolidation.
Formal application
You'll provide proof of identity and address, income documentation, bank statements, details of the debts you're consolidating, and information about your property and current mortgage. The lender runs a credit check at this stage.
Valuation
The lender arranges a valuation to confirm your property supports the loan amount requested. This might be an automated valuation, a desktop valuation, or a physical inspection, depending on the lender and your circumstances.
Underwriting
The lender's underwriters review your complete application and may come back with questions or requests for extra documentation. Responding quickly helps keep the process moving.
Mortgage offer
Once underwriting is complete, you'll receive a formal mortgage offer setting out the terms of your new mortgage. Check the loan amount, product fees, and terms and conditions carefully.
Legal completion
Your solicitor or the lender's conveyancer handles the legal work, including title checks, searches, redeeming your existing mortgage, and registering the new one.
Completion and debt payoff
On completion day, your new lender pays off your existing mortgage and releases the additional funds for debt consolidation, which are used to pay off your creditors. Keep documentation of every payment made, as some lenders ask for proof that debts have been cleared.
Before committing to consolidation through remortgaging, it's worth considering whether one of these alternatives might suit your situation better.
A secured loan sits behind your main mortgage as a separate loan secured against your property. This can be useful if your current mortgage has a good rate you want to keep, if early repayment charges make remortgaging expensive, or if you only need to borrow a smaller amount. Alternatively, a further advance lets you borrow more from your existing lender without changing lenders or your current terms. Secured loan rates are typically higher than mortgage rates but lower than unsecured lending, and the application process is often quicker than remortgaging. You'll still have two payments to manage, and your home is still at risk if you don't keep up with payments.
If your debt is mainly on credit cards and you have good credit, a 0% balance transfer card could give you breathing room to pay down debt interest-free for a set period, though you'll typically pay a transfer fee. This only works if you can clear or significantly reduce the debt within the promotional period. If you can't, you'll face a much higher rate once it ends.
An unsecured personal loan used to consolidate multiple debts won't put your home at risk and offers a fixed repayment period, typically one to seven years. Monthly payments will usually be higher than mortgage consolidation because the term is shorter, but you'll typically pay less interest overall.
If you're struggling with debt and concerned about affordability, a debt management plan through a free debt charity might help. Organisations such as StepChange and National Debtline can negotiate with creditors on your behalf to freeze interest and arrange affordable payments. This affects your credit score and can take time, but it doesn't put your home at risk and provides structured support. If you're finding things difficult, free and impartial guidance is also available from MoneyHelper on 0800 138 7777.
For more serious debt situations, an IVA is a formal agreement with creditors to pay back what you can over a fixed period, with the remaining debt written off. This is a significant step with lasting credit implications and should only be considered after professional debt advice.
Sometimes the best approach is keeping debts separate but tackling them directly. The avalanche method focuses extra payments on the highest-interest debt first, while the snowball method clears the smallest debts first for quicker wins. Both require discipline and enough income to make meaningful extra payments, but neither puts your home at risk.
Some mistakes come up again and again. Here's how to avoid them.
Many people focus only on the reduction in monthly payments without working out how much more they'll pay in interest over the extended term. Ask for illustrations showing the total amount repayable, not just the monthly figure, and compare the total cost of keeping debts separate against consolidating.
Rushing to consolidate while locked into a mortgage with a substantial early repayment charge can wipe out any benefit and leave you worse off. Check your current mortgage terms first, and calculate whether waiting until your fixed period ends makes more sense.
If you clear your credit cards through consolidation but then run them up again, you'll end up in a worse position than before, with the same mortgage debt plus new card debt. Address the spending patterns that led to the debt before consolidating, and consider closing cards or reducing limits afterwards.
Different lenders take different views on debt consolidation and offer different terms for similar circumstances. Going with the first offer you find could cost you. Compare a wide range of lenders, or work with a broker who can do this on your behalf.
Not all debts make sense to consolidate. Low-interest car finance or a 0% credit card deal might be better left as they are. Evaluate each debt individually, and only consolidate the ones where the saving genuinely justifies the approach.
Arrangement fees, valuation costs, legal fees, and any early repayment charge can add up significantly. Get clear quotes for all costs before committing, and factor every fee into your comparison.
A longer term means lower monthly payments, but it also means paying interest for longer. Consider keeping the term as short as you can comfortably afford, or take a longer term initially and make overpayments when you're able to.
A few situations call for extra consideration when looking at a debt consolidation remortgage.
If you're self-employed, you'll typically need two to three years of accounts or tax returns to verify your income. Lenders calculate income differently: some use net profit, others use salary plus dividends, and some average income over multiple years. Recent changes in income can complicate applications, though some specialist lenders offer more flexibility.
If you've had late payments, defaults, or more serious issues in recent years, high-street lenders may decline your application. Specialist lenders exist for exactly these situations, though terms will typically be less competitive. The severity, recency, and whether issues have been resolved all affect your options.
Most lenders have maximum ages at application and at the end of the mortgage term. If you're approaching these limits, consolidation might require a shorter term or a specialist later-life product. For borrowers over 55 with substantial equity, equity release offers another way to access property wealth, though it works very differently from a standard mortgage.
If you bought through shared ownership, Help to Buy, or a similar scheme, consolidating debt through remortgaging is more complex. You may need permission from the housing association, or be limited in the loan-to-value you can achieve. Speak to an advisor before assuming consolidation is possible in these situations.
If you own multiple buy-to-let properties, lenders assess your overall portfolio position alongside the specific property being remortgaged. Debt consolidation against a buy-to-let property is possible but assessed differently from a residential mortgage, so make sure any advisor you work with understands both sides.
We're a broker, not a lender, and we're upfront about what that means. We don't make lending decisions or set rates. Instead, we compare a wide range of lenders to find suitable products, present your application in the best light, and guide you through the process.
Most brokers, including us, receive commission from lenders when a mortgage completes. This doesn't affect the rate you pay, as lenders offer the same terms whether you apply directly or through a broker. We'll always be transparent about any fees before you commit to working with us.
You can apply for a remortgage directly with lenders if you prefer. This might suit you if your situation is straightforward, you're confident comparing products, you have time to research and apply, and your current lender already offers a good deal.
A broker tends to add the most value when your circumstances are complex, you have credit issues, you want to compare a wide range of lenders, you're unsure which lenders will accept you, or you want support through the process.
If you're considering a debt consolidation remortgage and want to explore your options, here's how working with us typically works.
Checking your eligibility won't affect your credit score. We use soft searches initially, which aren't visible to other lenders. A full credit check only happens once you proceed with a formal application.

Common questions
Yes, though your options will be more limited and terms less competitive than for those with good credit. Specialist lenders focus on borrowers with credit issues, but you'll still need sufficient equity and demonstrable affordability. The worse your credit and the more recent the issues, the fewer options you'll have. Working with a broker experienced in adverse credit cases helps identify which lenders are most likely to accept your application.
This depends on your property value, existing mortgage, income, and the lender's criteria. Most lenders cap debt consolidation at 80-90% of property value (loan-to-value). Your borrowing is also limited by affordability, meaning what you can demonstrate you can repay based on your income and outgoings. As a rough guide, lenders typically allow total mortgage debt of around 4-4.5 times your income, though this varies by lender.
In the short term, remortgaging involves credit checks that can temporarily lower your score. However, consolidating debt often improves your score over time because you're paying off credit cards (reducing utilisation) and making regular, on-time payments on a single account. The impact varies based on your starting position and how you manage your finances afterwards.
Most applications complete within four to eight weeks from submission to completion. Straightforward cases with all documentation ready can complete faster. Complex situations, valuation issues, or slow responses to queries can extend this. Starting the process early and responding quickly to requests helps keep things moving.
You can usually consolidate most unsecured debts including credit cards, personal loans, overdrafts, and store cards. Some lenders have restrictions on consolidating certain debt types or may require proof that consolidated debts are paid off. Car finance with an outstanding balance might need to be settled separately. Your broker can advise on what's possible for your specific debts.
You can still remortgage, but you'll typically need to pay any early repayment charges on your current mortgage. These charges can be substantial in the early years of a fixed deal. Speak to an advisor about whether the benefits of consolidating outweigh these charges, or whether waiting until your fixed period ends makes more sense. Many lenders allow you to arrange a new mortgage a few months before your current deal ends.
It depends on your circumstances. Remortgaging to release equity can sometimes work out cheaper, but it means moving your entire mortgage balance onto a new rate and may involve exit fees on your current deal. A secured loan leaves your existing mortgage untouched, which can be better if you have a competitive rate locked in. It's worth comparing both options with actual figures for your situation before deciding.
Yes, though you'll need to provide more documentation than employed applicants. Most lenders want two to three years of accounts or tax returns. Some specialist lenders offer options with just one year's accounts. Income calculation methods vary between lenders, so finding one whose methodology works favourably for your situation matters. Accountant-certified accounts carry more weight than self-certified figures.
Typical fees include valuation (£150-£1,500), legal or conveyancing (£500-£1,500), an arrangement fee (£0-£2,000), and any early repayment charge on your existing mortgage. Some products have no arrangement fee but slightly less competitive rates. Your broker should provide a clear breakdown of all costs before you commit so you can factor them into your decision.
Generally, no. Most residential mortgage lenders don't allow business debt consolidation, as this crosses into commercial lending territory. If you have both personal and business debts, you might consolidate personal debts through remortgaging while addressing business debts separately. Some specialist products exist for business owners, but these typically involve commercial lending structures.
Usually yes, though the type varies. Some lenders accept automated valuations using property data for straightforward cases. Others require physical inspections, especially for larger loans or unusual properties. The valuation confirms the property value supports your borrowing request. If the valuation comes in lower than expected, it could affect your LTV and therefore the terms available to you.
Most mortgages allow overpayments up to a certain level each year without penalty, and some products are more flexible than others. If you want the option to pay down the consolidated debt faster when possible, look for products with good overpayment features. Making overpayments can significantly reduce the total interest paid over the mortgage term.
Once you've used the remortgage funds to pay off your credit cards, those accounts will show as settled. What you do with the cards afterwards is up to you. Some people keep them open for emergencies while being careful not to rebuild debt, while others close them entirely. If you're concerned about temptation, closing cards or reducing limits can help prevent falling back into debt.
Some lenders offer interest-only options for debt consolidation, particularly for higher-value properties or specific circumstances. However, many mainstream lenders require capital repayment mortgages for debt consolidation purposes. With interest-only, you're not paying down the debt, only the interest, so the full amount remains due at the end. This increases long-term costs and risk.
If your property is worth less than when you bought it, you'll have less equity available and might be in negative equity if you owe more than it's worth. This significantly limits your remortgaging options. In these situations, you might need to explore other debt solutions or wait for property values to recover before consolidation becomes viable.
Yes, lenders ask the purpose of additional borrowing as part of their assessment. Debt consolidation is an accepted reason, but lenders may want details of the debts being consolidated. Some may require proof that debts have been repaid after completion. Being upfront about the purpose helps ensure you get appropriate products and advice.
