Debt Consolidation in the UK: Is It Actually Worth It?
Consolidation loans can save you thousands or cost you more. Here's how to tell the difference, with UK-specific rates and worked examples.
TL;DR
Consolidation works when the new loan rate is meaningfully lower than your existing debts and you don't extend the term too much. A £8,000 consolidation at 7.5% over 4 years saves thousands versus credit cards at 23%. But stretching to 7 years doubles the interest. Run the numbers before committing.
Debt consolidation sounds like a magic trick: combine all your debts into one payment and suddenly everything is easier. Sometimes it is. Sometimes it costs you more. Here's how to tell the difference.
What debt consolidation actually means
You take out a single new loan, use it to pay off all your existing debts, and then make one monthly payment on the new loan. That's it. The appeal is straightforward: instead of juggling five different creditors with five different rates and five different due dates, you have one.
In the UK, consolidation usually means an unsecured personal loan from a bank or building society. Some people remortgage or take a secured loan, but that puts your home at risk if you can't pay. We'd say avoid that unless you've spoken to a proper debt adviser first.
When consolidation saves you money
Consolidation works when the interest rate on your new loan is lower than the average rate across your existing debts. If you're paying 22 to 25 per cent on credit cards and can get a personal loan at 6 to 8 per cent, the maths is obvious.
For example: say you owe £8,000 across three credit cards averaging 23 per cent APR. Minimum payments would take over 20 years and cost thousands in interest. A £8,000 personal loan at 7.5 per cent over 4 years costs about £1,270 in total interest. That's a real saving.
Use our Loan Consolidation Calculator to run the numbers with your actual debts. It compares the total cost of your current payments against a consolidated loan.
When consolidation costs you more
Here's where people get caught out. If you stretch the repayment term to get a lower monthly payment, you might pay more in total interest even at a lower rate. A £8,000 loan at 7.5 per cent over 4 years costs £1,270 in interest. Stretch that to 7 years and the interest jumps to £2,260. Lower monthly payment, higher total cost.
The other risk: if you consolidate your credit card debt and then start spending on the now-empty cards, you end up with more debt than you started with. This is common enough that debt advisers call it the consolidation trap.
Consolidation vs. balance transfers vs. formal solutions
If your debt is mostly on credit cards and your credit score is decent, a 0 per cent balance transfer card might save you more than a consolidation loan. Some balance transfer deals offer up to 36 to 38 months at 0 per cent. The catch is the transfer fee (typically 1.5 to 3.5 per cent) and the need to clear the balance before the offer ends.
If your debts are large enough that you can't realistically pay them off in a few years, consolidation might not be the answer either. A Debt Management Plan, IVA, or DRO could be more appropriate. We cover those in our UK debt solutions guide. Free advice from StepChange (0800 138 1111) can help you figure out which route makes sense.
How to check if consolidation works for you
Start with two numbers: your total debt and your average interest rate. If you can get a consolidation loan at a meaningfully lower rate without extending your repayment term too much, it's probably worth it.
Check your debt-to-income ratio with our DTI Calculator. Most lenders want to see a ratio below 35 to 40 per cent before approving a personal loan. If your ratio is higher, you might struggle to get approved at a competitive rate.
Then run the comparison in our Loan Consolidation Calculator. It shows the total interest paid under both scenarios so you can make an informed choice.
