What is a debt consolidation mortgage?
It is not a separate product. It is an ordinary mortgage where part of the money raised is used to repay other borrowing — credit cards, personal loans, car finance or an overdraft. Some lenders describe it as capital raising for debt consolidation, which is a more honest name for what is happening.
The appeal is straightforward. Unsecured borrowing is usually charged at a much higher rate than a mortgage and repaid over a few years, so the monthly commitment can be heavy. Spread the same balance over a mortgage term at a mortgage rate and the monthly figure falls sharply. What has actually happened, though, is that the debt is now secured on your home and will take far longer to repay.
How does remortgaging to consolidate debt work?
There are three routes, and which one suits you depends mostly on your existing mortgage rather than the debt itself.
- Remortgage with capital raising — You move your whole mortgage to a new lender and borrow more than you currently owe, with the extra used to clear the unsecured balances. Usually the cheapest route when your existing deal is ending anyway.
- Further advance — You borrow additional money from your current lender alongside your existing mortgage. Useful when you are locked into a rate you do not want to lose, though the advance is often priced higher than the main loan.
- Second charge mortgage — A separate loan secured behind your main mortgage, from a different lender. The rate is higher, but your main mortgage is untouched — which can work out cheaper overall if leaving it early would trigger a large early repayment charge.
Most lenders pay your creditors directly at completion rather than sending the money to you, so they can be certain the debts are actually cleared.
Can you consolidate credit cards into your mortgage?
Frequently, yes. Credit card balances are the most common thing people consolidate, largely because the rates are the highest and the minimum payments can keep a balance alive for years.
The thing to be honest with yourself about is what happens to the cards afterwards. The single most common way consolidation goes wrong is that the balances are cleared, the cards stay open, and eighteen months later there is unsecured debt again — on top of a larger mortgage. If the cards are closed or put genuinely out of reach, consolidation stands a much better chance of doing what you wanted.
Can you consolidate personal loans and car finance?
Personal loans usually can be, though the arithmetic is less compelling than with credit cards because loan rates are lower and the term is already fixed and finite. If a loan has two years left to run, moving it onto a twenty-year mortgage will reduce the monthly payment and increase the total cost considerably.
Car finance depends on the agreement. A hire purchase or PCP agreement is not simply a debt you can clear — there may be a settlement figure, and with PCP the car may not be yours to keep. Check the settlement position with the finance company before assuming it can be folded in.
Potential advantages
- One payment instead of several — Simpler to manage, and for some households that alone reduces a lot of stress.
- A lower monthly commitment — Often substantially lower, which can free up genuine breathing room in a tight budget.
- A lower interest rate on the balance — Mortgage rates are typically far below credit card rates, so the cost per pound borrowed falls.
- Improved monthly affordability — Clearing unsecured commitments can improve how future lenders assess you, provided the balances do not rebuild.
Potential disadvantages
- You are securing debt against your home — This is the important one. Unsecured debt is unpleasant to fall behind on; secured debt puts your home at risk if you do not keep up repayments.
- You will usually pay more in total — A lower rate over a much longer term commonly costs more overall than a higher rate over a short one.
- Costs to set it up — There may be product fees, valuation fees, legal fees, an early repayment charge on your current deal, and our advice fee.
- It does not address why the debt built up — If spending consistently exceeds income, consolidation treats the symptom and buys time rather than solving the problem.
- Your equity reduces — Borrowing more against the property leaves less equity, which matters if values fall or you want to move.
Why the lowest monthly payment is not necessarily the cheapest option
Almost every debt consolidation conversation starts with "what would my new monthly payment be?" It is the wrong first question, because the answer is always encouraging — stretching any debt over a longer term lowers the monthly figure. That is arithmetic, not a good deal.
The better question is what it will cost in total, and over how long. Take £20,000 of unsecured debt being repaid over four years. Move it onto a mortgage over twenty years and the monthly payment falls dramatically, but you are now paying interest for sixteen additional years. Our calculator shows both figures side by side for exactly this reason.
That does not make consolidation wrong. If the monthly relief is what keeps a household stable through a difficult period, that has real value. It just needs to be a decision made with the total cost in view, and ideally with a plan to overpay once things ease.
What lenders look at
- Loan to value — Most mainstream lenders cap capital raising for debt consolidation at around 80–85% of the property value, and some stop at 75%. The more equity you have, the wider the choice and the better the rate.
- Affordability — The lender assesses the new total payment against your income, stress tested at a higher rate. Because the consolidated debts are being cleared, they usually drop out of the calculation — which is often what makes the numbers work.
- Credit history — Recent missed payments narrow the field considerably, though specialist lenders will often still consider it. Older, settled issues matter much less than people expect.
- Why the debt arose — A one-off event reads very differently to balances that have climbed steadily for three years.
- Early repayment charges — If you are inside a fixed rate, leaving it early may cost a percentage of the balance. Sometimes that alone makes a further advance or second charge the better route.
Secured versus unsecured debt
It is worth being clear about what changes. Unsecured debt — credit cards, most personal loans, overdrafts — is not tied to any asset. If you fall behind, the consequences are serious: default notices, damage to your credit file, court action in some cases. But your home is not directly at stake.
Secured debt is different. Once a balance forms part of your mortgage, it is secured against your property, and persistent non-payment can ultimately lead to repossession. That is the trade you are making in exchange for the lower rate and the lower monthly payment, and it deserves proper thought rather than a quick yes.
When people typically explore consolidation
- A fixed rate is ending anyway — There is no early repayment charge to pay, so the additional borrowing can be arranged as part of a remortgage you were doing regardless.
- Income has dropped — Reduced hours, a change of job or going self-employed can make previously comfortable commitments unmanageable.
- Debt built up through a specific event — A car replacement, a period of illness, a separation, or a run of unavoidable costs.
- Several high-rate balances at once — Where the combined interest is the real problem rather than the size of the debt.
- Preparing to move house — Some buyers consolidate to improve affordability before applying for a larger mortgage, though lenders look closely at this.
If your debts are large relative to your income, or you are already missing mortgage payments, more secured borrowing may well make things worse. Free, impartial advice is available from Citizens Advice Scotland, StepChange or your local council money advice team, and there are Scottish options such as the Debt Arrangement Scheme that may suit you better. We would tell you that plainly rather than arrange something unsuitable.
Why advice matters here
Debt consolidation is one of the areas where the gap between the best and worst outcome is widest. The same £20,000 can be added over ten years or twenty-five, at a mainstream rate or a specialist one, through a remortgage or a second charge — and the difference in total cost runs to many thousands of pounds.
Consolidating debt into a mortgage is a regulated activity, and we have to assess whether it is genuinely suitable for you rather than simply available. In practice that means we will sometimes tell you not to do it, or to consolidate less than you asked about, or to keep the term short even though it means a higher monthly payment. That is the point of advice.
