What Is Debt Consolidation?
Debt consolidation combines multiple debts into a single new loan or credit facility - ideally at a lower average interest rate - so you make one monthly payment instead of several. It doesn't reduce what you owe; it restructures how you owe it.
There are three main ways to consolidate debt in the UK:
Unsecured Consolidation Loan
A personal loan used to pay off multiple debts. Fixed monthly payments, fixed term, fixed rate. No asset at risk. Rates from around 5-15% for good credit scores, higher for poor credit. Best for debts totalling £2,000-£25,000.
0% Balance Transfer Card
Move credit card balances to a 0% card. No interest for 12-29 months. Small transfer fee (1-3%). Only works for credit card debt, not loans or overdrafts. See our balance transfer guide.
Secured Loan (2nd Charge)
Borrow against your home. Lower rates but your home is at risk if you miss payments. Only appropriate for very large debt amounts where unsecured options aren't available. Avoid for lifestyle or consumer debts.
When Debt Consolidation Works
Consolidation produces a real financial benefit when all four of these apply:
- The new rate is lower than your current average rate. If you have credit cards at 22-28% APR and can consolidate into a personal loan at 8%, you save significantly in interest. Calculate your current weighted average rate before deciding.
- You close the consolidated accounts. The most common trap: people consolidate card debt into a loan, then slowly run the cards back up - ending up with both the loan AND new card balances. Close or cut up the consolidated accounts immediately.
- You don't extend the term excessively. A lower monthly payment sounds appealing, but if you stretch from 3 years to 7 years, you might pay more total interest despite a lower rate. Always compare total cost of credit, not just the monthly payment.
- You've dealt with the underlying behaviour. Consolidation is a tool, not a fix. If the debt came from overspending, consolidation without a budget change just puts you back in the same position - with an extra loan on top.
When Consolidation Is a Mistake
Running up new debt: Consolidating and keeping cards open leads to double debt. Close the accounts right after consolidation.
Using a secured loan for unsecured debt: Don't put your home at risk to pay off credit card debt. If you can't repay the secured loan, you lose your home - a disproportionate outcome for consumer debt.
Ignoring early repayment charges: Some personal loans charge exit fees. Calculate whether the consolidation saving actually beats the cost of leaving your current loans early.
Very poor credit score: If your score is low, consolidation loan rates will likely be high (20-40% APR) - potentially worse than what you already have. A debt management plan through StepChange may suit you better.
How to Calculate Whether Consolidation Saves You Money
Here's a practical example with three debts:
| Debt | Balance | APR | Monthly Interest |
|---|---|---|---|
| credit card A | £2,500 | 28% | £58 |
| credit card B | £1,800 | 22% | £33 |
| Overdraft | £700 | 40% | £23 |
| Total | £5,000 | Avg ~27% | £114/month |
A consolidation loan at 9% APR over 3 years: monthly payment around £159, total interest around £724. Staying on minimum payments across all three debts could take 15+ years and cost £3,000+ in interest. The consolidation saves roughly £2,000 and clears the debt 12 years faster.
