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:

Most common

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 ~5–15% for good credit scores, higher for poor credit. Best for debts totalling £2,000–£25,000.

For card debt only

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.

High risk

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 genuine financial benefit when:

  1. 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.
  2. You close the consolidated accounts. The most common consolidation trap: people consolidate card debt into a loan, then slowly run the cards back up — ending up with both the loan AND the card balances. Close or cut up the consolidated accounts immediately.
  3. You don't extend the term excessively. A lower monthly payment sounds appealing, but if you extend from 3 years to 7 years, you might pay more total interest despite a lower rate. Always compare total cost of credit, not just monthly payment.
  4. You've addressed the underlying behaviour. Consolidation is a tool, not a solution. If the debt was caused by overspending, consolidation without a budget change leads back to the same position — but with an additional loan.

When Consolidation Is a Mistake

⚠️ Common consolidation traps

Running up new debt: Consolidating and keeping cards open leads to double debt. Close the accounts immediately after consolidation.

Using a secured loan for unsecured debt: Never 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 consequence for consumer debt.

Ignoring early repayment charges: Some personal loans charge ERCs. Calculate whether the consolidation saving exceeds the exit cost from existing loans.

Very poor credit score: If your credit score is low, consolidation loan rates will be high (20–40% APR) — potentially worse than your current rates. A debt management plan through StepChange may be more appropriate.

How to Calculate Whether Consolidation Saves You Money

Example: You have three debts:

DebtBalanceAPRMonthly Interest
Credit card A£2,50028%£58
Credit card B£1,80022%£33
Overdraft£70040%£23
Total£5,000Avg ~27%£114/month

A consolidation loan at 9% APR over 3 years: monthly payment ~£159, total interest ~£724. Compare to continuing minimum payments on current debts: could take 15+ years and cost £3,000+ in interest. The consolidation saves approximately £2,000+ and clears debt 12 years faster.

Frequently Asked Questions

It's harder but not impossible. With a poor credit score, mainstream lenders may decline or offer high rates. Options include: credit union loans (often more accessible and cheaper than payday-style lenders); secured loans (risky — only if you have equity and fully understand the risk); or — more appropriately — a free Debt Management Plan through StepChange, which achieves similar outcomes (one payment, potentially frozen interest) without a new loan.
Not automatically. You need to actively pay off and then close (or cut up) the credit card accounts after the loan funds arrive. If you leave the cards open with a zero balance, the temptation and opportunity to run them back up remains. Close them immediately after consolidation — this removes the risk and simplifies your credit profile, though you'll need to build up a credit history with new accounts over time if needed.
A personal consolidation loan can be arranged in as little as 24–48 hours online. Repayment of the consolidated debt then takes the loan term — typically 1–5 years depending on the amount and your chosen monthly payment. A 0% balance transfer completes within 3–7 working days and then runs for the promotional period. The key metric isn't how quickly you consolidate — it's having a plan to clear the resulting balance before the rate rises.
Important: Consolidation can help or harm depending on your situation. If in doubt, get free advice from StepChange or Citizens Advice before taking on new debt. Secured loans put your home at risk. Not financial advice.
