Debt Consolidation Loans UK (2026)
Roll multiple debts into one monthly payment — at a single, potentially lower, rate.
Debt consolidation is one of the most mathematically-appealing but most frequently misused UK borrowing products. Used correctly — to replace several high-APR credit cards with one lower-APR loan and a fixed payoff date — it saves hundreds or thousands of pounds in interest. Used badly — as a way to 'free up' credit cards that then get run up again — it doubles your debt. Below: when consolidation works, the maths to run first, and the cheaper alternatives most people should try first.
The maths of consolidation
Step 1: list every existing debt with balance, APR, and minimum payment. Step 2: calculate your weighted average APR = (sum of balance × APR) / total balance. Step 3: find a consolidation loan with an APR at least 3-5 percentage points below that weighted average. Step 4: make sure the new monthly payment is less than your current total minimum payments — but not so much less that the term has ballooned.
Example: £12,000 across three cards
| Debt | Balance | APR | Monthly minimum |
|---|---|---|---|
| Card A | £5,000 | 24.9% | £125 |
| Card B | £4,000 | 22.9% | £100 |
| Card C (store card) | £3,000 | 29.9% | £75 |
| Total | £12,000 | ~25.7% weighted | £300 |
| Consolidation loan (5 yr at 9.9%) | £12,000 | 9.9% | £254 |
In this example, consolidation saves around £46/month and guarantees clearing the debt in 5 years. At minimum payments on the cards, it would take 20+ years and cost roughly £14,000 in interest. At the 9.9% consolidation loan, total interest is about £3,240.
When debt consolidation is a bad idea
- Your weighted average APR is already under 10% — little room to save.
- You're considering consolidating into a secured loan (your home is at risk).
- You haven't changed the spending behaviour that caused the debt — consolidation then just doubles it.
- You're in a DMP or IVA — consolidation usually violates those arrangements.
Better options to consider first
- 0% balance transfer credit card — for total debt under £8,000 you can clear in under 21 months, this usually beats a consolidation loan.
- StepChange free advice — they often find solutions (DMP, IVA, or just negotiated reduced payments) that consolidation wouldn't provide.
- Credit-union consolidation loan — APR capped at 42.6% and often more generous to lower credit scores than mainstream lenders.
Questions answered
A single new loan used to pay off multiple existing debts — credit cards, store cards, overdrafts, other loans. You replace several monthly payments at varying rates with one fixed monthly payment at (hopefully) a lower overall rate. UK debt consolidation loans typically range from £5,000 to £25,000.
Only if two conditions hold: (1) the new loan's APR is meaningfully lower than the weighted average of your existing debts, and (2) you don't immediately run up new balances on the cleared cards. Consolidation without behaviour change just increases your total debt.
Short term: a small dip (5-15 points) from the hard search when applying. Medium term (3-12 months): usually a rise, because utilisation drops when you clear credit card balances and you're making on-time payments on a single tracked loan.
The same as any UK personal loan — depends on your credit score and loan size. Prime borrowers taking £10,000+ can get 6-9% APR; average credit 10-15%; poor credit 20%+. Compare the new APR against the weighted average of what you currently pay (add each debt's balance × APR, divide by total balance).
If your total debt is under £8,000 and you can clear it within 21 months, usually yes. A 0% balance transfer card charges a 3-5% transfer fee upfront and 0% interest for 21 months — cheaper than any personal loan if you pay it off on time. For larger amounts or longer horizons, a consolidation loan's fixed payments and longer term may be more realistic.
Almost never recommended. A secured debt consolidation loan (a 'second charge mortgage' or 'homeowner loan') turns unsecured debt into secured debt. If you miss payments, your home is at risk. Only consider if the APR difference is huge and your income is stable.
Only if the new term is similar to or shorter than the weighted average of your current debt terms. Many people consolidate into a longer term (7 years vs 3-4), which reduces the monthly payment but increases total interest paid over the loan. Run the numbers on total repayable, not just monthly.
Not typically. Individual Voluntary Arrangements (IVAs) and Debt Management Plans (DMPs) already freeze interest and consolidate payments. Taking a new loan to 'consolidate' existing debts under one of these arrangements is usually forbidden by the terms. Speak to StepChange or your IVA supervisor first.
Consolidation: you borrow new money to pay off existing debts, keeping full control. Debt management: a third party (typically a charity like StepChange) negotiates reduced payments with creditors; there's no new loan. Consolidation preserves your credit score better; debt management helps when you can't afford full repayments.
