Debt Consolidation UK — Is It a Good Idea?

8 min read · UK focused · Updated 14 Nov 2026

Debt consolidation means taking out one new loan or card to pay off several existing debts, so you have one payment instead of many. In the UK that is usually a personal loan, a 0% balance transfer card or a loan secured on your home. It is a good idea only if the new debt costs less in total than the old ones and you stop using the accounts you clear. A lower monthly payment on its own often means paying more interest over a longer time.

How debt consolidation works

You borrow enough to clear several debts, pay them off, and then repay the one new debt. The total you owe is the same on day one; what changes is the interest rate, the monthly payment and how long you pay for.

Say you have three credit cards and an overdraft. Each has its own rate, minimum payment and due date. If you take a personal loan for the combined balance and use it to clear all four, you are left with a single fixed monthly payment and an end date. That simplicity is part of the appeal. The bigger question is cost: whether the new rate, term and any fees add up to less interest than you would pay by clearing the original debts directly.

Ways to consolidate debt in the UK

Unsecured personal loan

The most common route. You borrow a fixed amount at a fixed rate over a fixed term, often one to seven years, and nothing is secured on your home. The rate you are offered depends on your credit file. Adverts show a representative APR, which only has to be offered to at least 51% of successful applicants, so check your personal rate with a soft-search eligibility checker before you apply.

0% balance transfer credit card

For card debt, a balance transfer moves what you owe to a new card that charges no interest for a set period. There is usually a one-off transfer fee of a few per cent of the balance. It works well if you can clear the balance before the 0% period ends; whatever is left then reverts to the card's standard rate. The balance transfer calculator shows the monthly payment that clears it in time, and our 0% balance transfer strategy guide covers the pitfalls.

Secured loan or remortgage

A homeowner loan or extra borrowing on your mortgage can offer a lower rate and a longer term. The trade-off is serious: unsecured card debt becomes debt secured on your home, so falling behind can put your home at risk, and spreading it over many years can mean paying much more interest overall. Think carefully before securing other debts against your home.

A debt management plan is not consolidation

A debt management plan also leaves you with one monthly payment, but there is no new borrowing. A provider shares your payment between creditors and asks them to freeze interest. It suits people who can't afford their current payments. Our consolidation vs DMP guide compares the two side by side.

Does debt consolidation save money? A worked example

It saves money when the rate drops and the term doesn't stretch. Here is £8,000 of credit card debt at an average 23.9% APR, compared with a personal loan at 9.9% APR and no fees:

The 3-year loan saves about £3,300 and finishes a year sooner, because the payment stays the same while the rate falls. The 5-year loan still beats the cards, but the lower monthly payment costs about £900 more interest than the 3-year loan. If the only rate you can get is close to what your cards charge, consolidation saves little or nothing. Arrangement fees and early repayment charges reduce the saving further.

When debt consolidation is a good idea

• You can get a clearly lower rate than the average across the debts you would clear.
• You can afford the payment on a realistic budget, without relying on overtime or new credit.
• The term is similar to how long you would take to clear the debts anyway, not years longer.
• You will stop using the cleared accounts. Keeping a card open can help your credit score, but only if you don't spend on it again.

When to avoid it

• You are already behind on bills or using credit to cover essentials. More borrowing is likely to make things worse; free advice comes first.
• The main benefit is a lower monthly payment from a longer term. That usually means more interest in total.
• The offer is secured on your home and you aren't sure you can keep up for the whole term.
• You are being charged upfront fees by a broker or "debt help" firm. Free debt advice is always available, and you should never have to pay to be told about your options.

If consolidation doesn't stack up, clearing the debts yourself can work just as well. The debt repayment calculator shows your debt-free date with the debts you have now, and debt snowball vs consolidation explains when each approach wins.

Does debt consolidation affect your credit score?

Applying for a loan or card leaves a hard search on your credit file, which can lower your score slightly for a few months, and several applications close together look worse. Most lenders offer an eligibility check that uses a soft search, which other lenders can't see. Once the loan is running, paying on time and lowering your total balances tend to improve your score. The real risk is running the cleared cards back up, which leaves you with the loan and the card debt. Our guide to improving your credit score covers rebuilding in more detail.
