There's no single "best" debt consolidation strategy — the right approach depends on how much you owe, the interest rates involved, your credit profile, and whether you're simplifying manageable debt or facing genuine financial difficulty. Here's an honest, structural comparison of the main options available to UK borrowers.
1. Unsecured debt consolidation loan
Combines multiple debts into one fixed-rate personal loan with a single monthly payment. Best suited to those with a reasonable credit profile who can access a rate meaningfully lower than their blended existing rate. See our full guide to using a debt consolidation loan the smart way, and model your specific numbers with our Debt Consolidation Savings Calculator.
2. 0% balance transfer credit card
Moves credit card debt onto a new card offering 0% interest for a promotional period, usually in exchange for a one-off balance transfer fee. Works best for smaller, credit-card-specific debts that can realistically be cleared within the promotional window — less suitable for larger debts or a mix of loan and credit card balances.
3. Secured (homeowner) consolidation loan
Uses your home as security to access potentially lower rates and larger consolidation amounts, but puts your property at risk if repayments aren't maintained — see our comparison of personal vs secured loans before considering this route, given the meaningfully higher stakes involved.
4. Mortgage further advance or remortgage to consolidate
Some homeowners release equity via a mortgage further advance or remortgage specifically to clear higher-interest unsecured debt. This can lower the overall interest rate significantly, but spreading short-term debt over a much longer mortgage term can increase the total interest paid over time if not managed carefully — always compare total cost, not just the rate.
5. Free debt management plan via a charity
For those genuinely struggling rather than simply wanting to simplify manageable payments, a free debt management plan (DMP) arranged through a charity such as StepChange can consolidate payments into a single affordable amount, sometimes with creditors agreeing to freeze interest, without taking on any new borrowing at all.
Comparing the options at a glance
| Strategy | Best for | Key risk |
|---|---|---|
| Unsecured consolidation loan | Reasonable credit, moderate debt | Term extension increasing total cost |
| 0% balance transfer card | Smaller, card-specific debt | Interest resumes sharply after promo period |
| Secured consolidation loan | Larger debts, strong equity | Home at risk |
| Mortgage further advance/remortgage | Significant debt, willing to extend mortgage term | Short-term debt spread over decades |
| Free debt management plan | Genuine financial difficulty | None — but affects credit file during the plan |
A word on discipline, regardless of strategy
Every consolidation strategy shares one common risk: continuing to spend on cleared credit accounts, effectively creating new debt on top of the consolidated amount. Whichever route you choose, pair it with a firm commitment to close or avoid using cleared credit facilities.
The bottom line
The "best" debt consolidation strategy genuinely depends on your specific numbers and circumstances — there's no universal answer. Compare the total cost (not just the monthly payment) across at least two or three realistic options, and if you're struggling rather than simply simplifying, speak to a free debt charity before committing to any new borrowing.
