Yes, you can remortgage to pay off debt by releasing equity from your home as a lump sum, provided your payment history and affordability support the application. The central trade-off is plain: lower monthly outgoings now, but more interest over a longer term and your home at risk if payments are missed.

How does remortgaging to pay off debt actually work?
Remortgaging to pay off debt works by releasing equity as a lump sum from the value of your property, which is then used to repay debts. According to StepChange, a remortgage can also reduce the monthly mortgage payment, freeing up money for other debts.
A lender bases a remortgage application on your credit file, the value of the house and how much you want to borrow. StepChange explains that these three factors shape what offer, if any, a lender will make.
Mortgage debt consolidation acts as a single loan that lets you borrow money against your property to repay debts such as unsecured loans, credit cards and store cards. NatWest describes this as one loan secured against your home, replacing several unsecured debts with one monthly payment.
Debt consolidation can only be completed on a residential mortgage and is subject to eligibility and credit score. NatWest also states that debt consolidation cannot be taken on an interest-only repayment basis.
What debts can I consolidate onto my mortgage?
You can consolidate unsecured loans and hire purchase agreements with more than 12 months to run, credit cards, store cards and catalogue accounts unless they are at 0%, overdrafts and student loans. NatWest lists these as the debts that can be moved onto a mortgage.
You cannot consolidate unsecured loans or hire purchase agreements with less than 12 months to run, nor credit cards, store cards or catalogue accounts at a 0% interest rate. NatWest sets out these exclusions clearly.
The difference between secured and unsecured debt matters here. Unsecured debt is not tied to an asset, so a lender cannot automatically take your home if you miss payments. Moving unsecured debt onto a mortgage changes that risk, because the debt becomes secured against your property.
What are the real costs of consolidating debt this way?
The real costs are lower monthly outgoings now, set against more interest over the full term and reduced equity in your home. NatWest notes that borrowing on a mortgage to consolidate debts can reduce monthly outgoings, normally carries a lower interest rate than unsecured finance and can help with budgeting.
The cons are equally clear. NatWest warns that consolidating debts onto a mortgage can mean paying more interest over a longer term, putting the home at risk if payments are missed and reducing equity in the property.
The NatWest illustrative example makes the trade-off concrete. NatWest compares £15,000 at 7% over 5 years, which costs £297 per month and £2,821 in total interest, with £15,000 at 4% over 15 years, which costs £111 per month but £4,971 in total interest. That is an extra £2,150 in interest.
A lower monthly payment is not the same as a cheaper deal overall. The shorter term costs less in total interest, while the longer term eases monthly pressure but costs more by the end.
Will my credit history stop me remortgaging to clear debt?
No, you can remortgage even if you have debt, because what matters most is how well payments to those debts are being kept up. StepChange states that a clean payment record on existing debts is more important than the fact that debts exist.
Missed payments affect your credit file and can make it harder to get a new mortgage at a good rate. StepChange explains that missed payments to debts are recorded and weigh against you when a lender reviews the application.
Being in arrears on a mortgage or other debts affects the credit rating and makes a good mortgage offer unlikely. StepChange is direct on this point: arrears damage your credit rating and reduce the chance of a competitive offer.
Lenders apply their own eligibility and credit score checks beyond general statements. NatWest confirms that debt consolidation is subject to eligibility and credit score, which means each lender will assess your file differently.
Should I remortgage now or wait until my current deal ends?
It depends on the early redemption fee. StepChange explains that remortgaging before a current mortgage deal has ended can trigger an early redemption fee, also called an exit fee, which can be large enough to wipe out the benefit of consolidating.
Remortgaging can also reduce the monthly mortgage payment, freeing up money for other debts. StepChange notes this as a legitimate reason to remortgage, but the timing still matters because of exit fees.
Additional borrowing for existing customers does not need to be over the same term as the main mortgage. NatWest states this as an option for existing mortgage customers, which can change the timing calculation.
Is remortgaging to pay off debt ever a bad idea?
Yes, remortgaging to pay off debt can be a bad idea if you are financially struggling or have missed repayments. NatWest states that adding debts to the mortgage might not be advisable in those circumstances.
Putting your home up as security means missed payments put it at risk. NatWest lists this as one of the main cons of consolidating debts onto a mortgage, and it is the risk that changes everything.

How can a mortgage broker help me decide?
A mortgage broker can help by giving you one-to-one support from first conversation to completion, with a whole-of-market lender search and plain-English trade-off explanations. That means looking beyond a single lender’s criteria and checking how different lenders treat your income, credit file and property value.
Andrew Westwood Mortgage Broker offers remortgage advice and rate reviews, mortgage repayment and affordability guidance, and support for first-time buyers, home movers, self-employed borrowers and buy-to-let landlords. The value is clarity on what you can borrow, what it costs each month and what happens next.
Dealing with one named person rather than a call centre matters when the decision involves your home. A broker can walk through the mortgage repayment and affordability numbers with you, including the true cost of consolidating debt over the full term.
The decision to remortgage to pay off debt is not just about whether you can, but whether you should. A broker can set out the trade-offs without pressure, so you understand the monthly saving, the total interest and the risk to your home before you commit.
