Consolidating Debt Onto Your Mortgage: Read This First

Rolling credit cards and loans into your mortgage can lower your monthly payments. It can also turn debt you could walk away from into debt secured on your home. Here is the honest picture.

Updated June 2026Borrowing7 min read

Rolling your credit cards and loans into one payment secured on your home can lower what you pay each month, and for some people it genuinely helps. But it can also turn debt you could otherwise walk away from into debt secured against your house, and quietly cost you far more over time. Before you do it, read this.

What consolidating debt onto your home means

Debt consolidation here means using a secured loan, a second charge mortgage, or a remortgage to pay off unsecured debts like credit cards, overdrafts and personal loans, replacing several payments with one. Because the new borrowing is secured on your property, it usually comes with a lower interest rate than the debts it clears.

The appeal: one lower monthly payment

The attraction is real. Instead of juggling several payments at different rates and dates, you have one payment, often at a lower rate and spread over a longer term, which can ease the pressure on a stretched budget month to month. For some households, that breathing room is exactly what they need.

The catch nobody likes to say out loud

There are two big risks, and they are easy to miss:

  • Unsecured debt becomes secured. A credit card is not tied to your home. Move it onto a secured loan and it is. If you then cannot keep up the payments, your house is at risk in a way it was not before.
  • A lower rate can still cost more. Spreading a short term debt over twenty or twenty five years means paying interest for far longer. Even at a lower rate, the total you repay can be much higher than if you had cleared the debt over a few years.

A simple way to see the real cost

Imagine clearing a debt you would have paid off in three years and instead spreading it over twenty. The monthly payment falls, which feels like a win, but you are now paying interest on that balance for two decades. That is why a lower monthly payment and a lower interest rate can still add up to more money out of your pocket overall. Always look at the total cost, not just the monthly figure.

When consolidation can genuinely help

It can be the right move in narrow circumstances: when the maths genuinely works once you compare the total cost, when you keep the new term as short as you can afford rather than stretching it to the limit, and crucially when you deal with whatever caused the debt, so you do not run the cards back up and end up worse off with your home now on the line.

Safer things to try first

  • Free, impartial debt advice from StepChange, National Debtline or MoneyHelper, Dealing with debt. This costs nothing and could save you from a decision you regret.
  • A nought percent balance transfer for credit card debt, if your credit allows it.
  • Talking to your existing lenders, who may agree a manageable plan.

Get proper advice before securing debt on your home

Securing debt against your home is a serious step, and a regulated adviser must check it genuinely leaves you better off before recommending it. If you are struggling with debt right now, speak to one of the free services above first. If consolidation still looks like the right answer after that, take regulated mortgage advice so it is done with your eyes open.

If you want someone to look honestly at whether consolidating is right for you, rather than just sell you a loan, Debbie at DS Financial can talk it through. For the mechanics of the borrowing itself, see what a second charge mortgage is and second charge vs remortgage.

General information, not financial advice. A second charge mortgage or secured loan is secured against your home, which may be repossessed if you do not keep up the repayments.

FAQs

Debt consolidation FAQs

Is it a good idea to consolidate debt onto my mortgage?
Sometimes, but not always. It can lower your monthly payments, but it secures previously unsecured debt against your home and can cost much more in total interest over a longer term. Get free debt advice or regulated mortgage advice before deciding.
Will consolidating debt lower my monthly payments?
Usually yes, because the rate is often lower and the term longer. But a lower monthly payment is not the same as paying less overall. Always compare the total cost, not just the monthly figure.
Does consolidating cost more in the long run?
It can. Spreading a short term debt over twenty or twenty five years means paying interest for far longer, so even at a lower rate the total repaid can be significantly higher. Keeping the term short helps limit this.
Can I consolidate debt with bad credit?
It may be possible through a specialist secured loan, but rates will be higher and your home will be at risk. Free debt advice should be your first step, as there may be a better route that does not involve securing debt on your home.
Is my home at risk if I consolidate debt onto it?
Yes. Moving unsecured debt onto a loan secured against your property means the home can be repossessed if you fall behind, which was not the case with credit cards or personal loans.
Where can I get free debt advice?
Free, impartial help is available from StepChange, National Debtline and MoneyHelper. They can review your whole situation at no cost and suggest options you may not have considered.
