What is debt consolidation?
Debt consolidation means combining multiple debts — credit cards, personal loans, overdrafts — into a single loan with one monthly payment and (ideally) one lower interest rate. The goal is to simplify your finances and reduce the total interest you pay.
Done well, it can save significant money and reduce financial stress. Done poorly, it can make things worse. Understanding the mechanics is essential before committing.
How debt consolidation works
You take out a new loan — personal loan, secured loan, or sometimes a 0% balance transfer credit card — and use it to pay off all your existing debts. You then repay the single consolidation loan over a set term.
Example: You have £3,000 on a credit card at 22%, £5,000 on another card at 19%, and a £2,000 personal loan at 15%. You consolidate all £10,000 into a single personal loan at 8% over 4 years. Monthly payments fall, total interest paid falls, and you have one simple payment.
Types of debt consolidation
Unsecured personal loan
Most straightforward option. No collateral required. Rates depend on credit score — typically 5–15% for good credit. Suitable for amounts up to £25,000–£50,000.
Secured loan (second charge mortgage)
Secured against your home. Lower interest rates (typically 4–9%) and higher loan amounts available. But your home is at risk if you can't repay. Appropriate only for larger amounts where the rate saving justifies the security risk.
0% balance transfer credit card
Transfer existing credit card balances to a card charging 0% for an introductory period (typically 12–28 months). Can be very cost-effective for credit card debt if you can clear the balance before the 0% period ends. A transfer fee usually applies (1–3%).
Remortgage to consolidate debt
Add unsecured debt to your mortgage. The lowest interest rate — but you're converting short-term unsecured debt into long-term secured debt. You may pay more in total interest even at a lower rate, and your home is at risk.
⚠️ Think carefully before securing debts against your home. Secured loans and remortgages for debt consolidation mean your property could be repossessed if you don't keep up repayments.
When debt consolidation makes sense
- You have multiple high-interest debts and can access a meaningfully lower rate
- Your credit score is good enough to qualify for a competitive consolidation loan
- You have the discipline not to accumulate new debt on the cleared cards/accounts
- The total cost (including any fees) over the loan term is less than your current path
When it doesn't make sense
- The consolidation rate isn't significantly lower than your current average rate
- You extend the term so much that total interest paid is actually higher
- You continue using the cleared credit cards and rebuild the same debts
- You have debt problems that require a more fundamental solution (IVA, debt management plan)
💡 Always calculate the total amount repayable under a consolidation loan vs your current path — not just the monthly payment. Lower monthly payments often mean a longer term and more total interest paid.
