UK Debt Repayment Strategy Guide 2026
UK debt repayment 2026 - avalanche vs snowball with worked figures, priority debts first, balance transfers, consolidation loans, DMPs, IVAs and bankruptcy, free advice.
Step 1: List every debt
Before any strategy, you need a complete inventory. For each debt:
- Lender name + account number
- Current balance
- Interest rate (APR)
- Minimum monthly payment
- Type (credit card, personal loan, store card, overdraft, mortgage, etc.)
- Priority or non-priority
Step 2: Identify priority vs non-priority debt
| Priority debt | Non-priority debt |
|---|---|
| Mortgage / rent | Credit cards |
| Council Tax | Store cards |
| Energy bills | Personal loans |
| Court fines | Overdrafts |
| Tax owed to HMRC | Payday loans |
| Child maintenance | Buy now pay later |
| TV Licence | Catalogue debts |
Priority debts get paid first regardless of interest rate, because the consequences of not paying them are more serious: losing your home, having your energy supply affected, or enforcement through the courts. Missing non-priority debts leads to charges, default notices and credit damage.
Step 3: Choose avalanche or snowball
Avalanche method (least interest)
- Pay minimum on all debts
- Put all extra money towards the HIGHEST APR debt
- When it is cleared, move to the next highest
- Continue until all cleared
Snowball method (quick wins)
- Pay minimum on all debts
- Put all extra money towards the SMALLEST BALANCE debt
- When it is cleared, move to the next smallest
- Continue until all cleared
Worked comparison: £15,000 across 3 debts
| Debt | Balance | APR | Minimum payment |
|---|---|---|---|
| Credit card A | £8,000 | 22% | £200 |
| Credit card B | £5,000 | 28% | £150 |
| Personal loan | £2,000 | 12% | £75 |
With £600/month available (minimums £425 + extra £175), and each cleared debt's minimum rolled into the next target:
- Avalanche (target Credit card B first): clears in 34 months, £5,263 total interest
- Snowball (target Personal loan first): clears in 35 months, £5,731 total interest
- Avalanche saving: £468
Simulated month by month with interest at APR / 12 on the outstanding balance. Real cards compound and calculate interest in different ways, so treat these figures as illustrative.
Tactical tools to accelerate repayment
0% balance transfer credit cards
Move existing credit card debt to a new card with 0% interest for a fixed period, usually for a transfer fee charged as a percentage of the balance. Strategy:
- Apply for a 0% balance transfer card
- Transfer the balance and note the fee
- Work out the monthly payment to clear it in the 0% period: (balance + fee) ÷ months
- Set up a direct debit for that amount
- Stop using the original card
Worked example: £8,000 on a 22% APR card, moved to a 24-month 0% card with a 3% fee:
- Transfer fee: £240
- Monthly payment needed: £343 over 24 months
- Cost: the fee only, if cleared within the 0% period
- Repaying the original card over 48 months instead: about £4,098 interest
- Saving: about £3,858
Debt consolidation loan
A single loan used to pay off several debts. Worth considering only if:
- Its APR is lower than the rates you pay now
- The total cost over the full term is lower, not just the monthly payment
- You stop using the cards you clear
- You can afford the fixed monthly payment
When repayment isn't feasible: formal options
Debt Management Plan (DMP)
- Informal agreement with creditors to repay in smaller amounts, unsecured debts only
- Not legally binding - creditors can still ask for the full amount or take action
- Set up yourself, through a free advice service, or through an FCA-authorised company (some charge fees)
- Does not reduce the amount you owe
Individual Voluntary Arrangement (IVA)
- Legally binding agreement with creditors to pay all or part of your debts
- Regular payments to an insolvency practitioner, who works out what you can afford and how long it lasts
- On the Individual Insolvency Register until 3 months after it ends; on your credit record for 6 years
Debt Relief Order (DRO)
- England and Wales only, for debts under £50,000 with little spare income and few assets
- Free; lasts 12 months. See our DRO guide
Bankruptcy
- Usually a last resort
- England and Wales: apply online, £680 fee
- Normally ends one year after it starts (Insolvency Act 1986 s.279)
- On your credit record for 6 years
- Assets can be used to pay creditors; some jobs restrict people who are bankrupt
- Different process in Scotland and Northern Ireland

Frequently asked questions
What's the best UK debt repayment method - avalanche or snowball?
Both pay the minimum on every debt and put any extra towards one debt at a time. Avalanche targets the highest interest rate first; snowball targets the smallest balance first. Avalanche always costs the same or less interest; how much less depends on your debts. In our worked example (£15,000 across three debts, £600 a month) avalanche saves £468 and finishes 1 month sooner. Snowball can still suit people who need early wins to keep going.
Should I pay off debt or save?
Compare the interest rate on the debt with what your savings earn after tax. Paying off a debt "earns" its interest rate with certainty, so high-interest borrowing such as credit card debt usually comes first. Keep a small emergency fund so an unexpected bill does not go back on a card, and keep up priority bills before anything else.
How do balance transfer credit cards work?
You move existing card debt to a new card charging 0% for a set period, usually for a one-off fee that is a percentage of the balance. Divide the balance plus fee by the number of 0% months and pay that by direct debit. Worked example: £8,000 at 22% APR moved to a 24-month 0% card with a 3% fee costs £240 and needs £343 a month. Repaying the original card over 48 months instead would cost about £4,098 in interest. Check the rate that applies when the 0% period ends.
What's a Debt Management Plan (DMP)?
An informal agreement with creditors to pay back your debts in smaller amounts over a longer period, for unsecured debts only. You can set one up yourself or through a debt management company authorised by the FCA; some companies charge a set-up fee and a handling fee. It is not legally binding: creditors can still ask for the full debt later or take action (gov.uk). Free debt advice charities can help you set one up.
When does an IVA make sense?
An Individual Voluntary Arrangement is a legally binding agreement with your creditors to pay all or part of your debts, through regular payments to an insolvency practitioner. It can give you more control of your assets than bankruptcy. It goes on the Individual Insolvency Register until 3 months after it ends and stays on your credit record for 6 years (gov.uk). Get free advice first: an IVA is not the right answer for everyone.
Should I consider bankruptcy?
Usually as a last resort. In England and Wales you apply online and it costs £680; bankruptcy normally ends one year after it starts (Insolvency Act 1986 s.279), and it stays on your credit record for 6 years. Assets can be used to pay creditors and some jobs restrict people who are bankrupt. The process is different in Scotland and Northern Ireland (gov.uk).
How do I check what debts I have?
The UK has three main credit reference agencies: Experian, Equifax and TransUnion. You have the right to a copy of what each holds about you, free of charge - look for the "statutory report" on their websites; you do not need a paid subscription (ICO). Challenge anything wrong with the lender and the agency.
What's priority debt and why does it matter?
Priority debts are those where not paying can lead to losing your home, having your energy supply affected or enforcement through the courts: mortgage or rent, Council Tax, energy, court fines, tax owed to HMRC, child maintenance and the TV licence. Non-priority debts such as credit cards, personal loans, store cards, overdrafts and buy now pay later lead to charges and credit damage. Deal with priority debts first, whatever their interest rate.
Should I get a debt consolidation loan?
Only if the new loan's APR is lower than what you pay now across your debts, the total cost over the full term is lower (a longer term can cost more even at a lower rate), and you stop using the cards you cleared. Consolidating and then running the cards up again leaves you with more debt than before.
Where do I get free UK debt advice?
StepChange (stepchange.org, 0800 138 1111), Citizens Advice (citizensadvice.org.uk), National Debtline (nationaldebtline.org) and MoneyHelper (moneyhelper.org.uk), which is backed by government and lists free advice services. You do not need to pay a company for advice that these give free.
