Remortgaging to pay off debt explained

Remortgaging can be an option for homeowners who want to replace their existing mortgage deal and use some of the new borrowing to clear other debts. For many people, the appeal is that mortgage interest rates can be lower than those on credit cards and many unsecured loans, and a remortgage may allow debts to be repaid over a longer period.

That said, remortgaging to pay off debt isn’t automatically the best choice for everyone. The right decision depends on the cost of the new mortgage, the amount you can borrow, your repayment affordability, and how long you plan to stay in the property.

How does a remortgage work when you’re clearing debt?

A remortgage is essentially switching your current mortgage to a new mortgage arrangement. When the purpose is to repay debt, the process usually looks like this:

• You apply for a new mortgage deal (often with a different lender, but not always).
• The new mortgage pays off your existing mortgage balance.
• Any additional funds you’re approved to borrow may be used to repay eligible debts (for example, credit cards or personal loans).
• Your mortgage repayments continue, now based on the new loan amount and the new interest rate/product terms.

In some cases, your current lender may offer a remortgage option or product switch that could still help you consolidate debts. In other cases, moving to a new lender may provide more suitable terms.

What debts can a remortgage be used to clear?

Remortgaging to pay off debt typically involves consolidating unsecured borrowing. Common examples include:

• credit cards
• personal loans
• overdrafts
• store cards

Lenders and mortgage products can differ in what they will allow to be repaid using remortgage funds, and they may require evidence of the debts and how the money will be used. It’s important to be clear about the debts you want to clear and how much you owe.

Will I be able to remortgage to clear debt?

Whether you can remortgage for debt consolidation depends on lender criteria and your personal financial position. Lenders will typically look at factors such as:

• Your income and employment situation (including whether it’s stable and how it’s evidenced)
• Your monthly outgoings, including existing debt repayments
• Your credit history and repayment behaviour
• The value of the property and the amount of equity you have
• How much you want to borrow and the overall affordability of the new mortgage

Even if you were approved for a mortgage when you bought the property, your circumstances may have changed since then—such as changes in income, additional commitments, or changes to your credit profile.

Equity and property value matter

Most remortgage arrangements require you to have sufficient equity in the property (or enough value relative to the mortgage balance you’re seeking). Equity can come from:

• paying down your mortgage balance over time
• property value increases since purchase

The more equity you have, the more flexibility you may have in terms of lender choice and product options.

Affordability checks: what lenders typically assess

When you remortgage to consolidate debt, the lender will still run an affordability assessment. That usually includes:

• your gross income and how reliable it is
• your regular committed spending
• your current debt repayments
• the proposed new mortgage payment
• any other financial commitments (for example, childcare costs or other loans)

A key point is that consolidating debt doesn’t remove the need to demonstrate affordability. If the new mortgage payment (including any fees and the effect of borrowing more) is too high relative to your income and expenditure, the application may not be approved.

How to maximise your chances of approval

While every lender has its own criteria, there are practical steps that can help strengthen an application when the goal is to clear debt:

• Avoid taking on new credit before the remortgage application.
• Keep debt repayments up to date and address any arrears.
• Be prepared with accurate documentation for income, outgoings, and the debts you want to clear.
• Use realistic figures for how much you want to borrow and what you can afford.
• Consider the overall plan, not just the debt payoff—your mortgage term, interest rate type, and monthly payment matter.

Things to consider before you remortgage to pay off debt

Remortgaging can reduce certain costs, but it can also extend the time you’re paying off borrowing. Before proceeding, consider:

• Do you have enough equity?
• What will the remortgage cost overall? (including fees and the total interest over the term)
• Will you clear the debt amount you expect?
• Will your monthly outgoings increase or decrease?
• Can you comfortably afford the new mortgage payments if interest rates change (for variable products) or if your circumstances shift?
• How long do you plan to stay in the property? Early exit costs or product changes can affect value.
• Is a fixed or variable rate more suitable for your situation and risk tolerance?

Alternatives to remortgaging for debt consolidation

A remortgage isn’t the only way to consolidate debt. Depending on your circumstances, alternatives may include:

• Unsecured personal loans (often with higher interest rates than mortgages)
• Debt management options through appropriate debt solutions
• Borrowing from family (where feasible and structured clearly)

Each option has different costs, repayment terms, and risks. The best approach depends on the size of your debts, your credit profile, and your ability to maintain repayments.

Remortgaging to pay off debt FAQ

Can I extend the term length of my mortgage to clear debt?

In some situations it may be possible to change the mortgage term when remortgaging. Extending the term can reduce the monthly payment, which may help affordability. However, a longer term can also mean paying more interest overall, so it’s important to compare the full cost and not just the monthly figure.

What are the alternatives to remortgaging?

Common alternatives include unsecured personal loans and other debt solutions. These may be more expensive than mortgage borrowing, and repayment terms are often shorter, which can affect monthly affordability.

Will checking options affect my credit score?

In general, initial eligibility checks carried out as part of advice may not impact your credit file in the same way as a full mortgage application. A formal application typically results in a lender credit search. The exact impact depends on how checks are performed and by whom.

Will bad credit stop me from remortgaging to pay off debt?

Bad credit can reduce the number of lenders and products available, but it doesn’t always rule out remortgaging. The key is whether you can meet affordability requirements and lender criteria, and whether the overall mortgage structure is acceptable.

Is it possible to consolidate debt without increasing risk?

It may be possible to structure a remortgage in a way that supports stability—such as choosing a repayment strategy you can sustain and selecting a rate type that matches your circumstances. The main risk to manage is whether the new mortgage payment remains affordable over time.
