UK household debt has grown dramatically. According to The Money Charity, average UK adult unsecured debt (excluding mortgages) reached £4,500+ in 2024. Credit cards average 25-35% APR. Buy-now-pay-later (Klarna, Clearpay) has normalised debt.
The FCA monitors over-indebtedness with the Debt Service Ratio (DSR).
What is DSR?
DSR = (Total monthly debt payments) ÷ (Monthly net income).
Includes: - Mortgage or rent - Personal loans - Credit card minimum payments - Overdraft fees - Store card payments - Buy-now-pay-later commitments - Car finance (HP, PCP)
The 3 thresholds
| Zone | DSR | Diagnosis |
|---|---|---|
| 🟢 Healthy | 0-30% | No compromise on saving capacity |
| 🟡 Caution | 30-45% | Financial stress |
| 🔴 Over-indebted | 45%+ | Urgent action required |
The 3 strategies to lower DSR
1. 0% balance transfer card
If you have credit card debt at 25-35% APR, balance transfer cards offer 12-30 months at 0% intro APR (Barclaycard Platinum, Tesco Bank, Santander). Transfer fee typically 2-3%, but the math is massive.
Example: £8,000 at 28% APR vs £8,000 at 0% for 24 months with 3% transfer fee. Standard interest cost: ~£2,500. Transfer cost: £240. Savings: £2,260.
2. Personal loan consolidation
Multiple debts: M&S Bank, Tesco Bank, Sainsbury's Bank, mainstream banks offer 6-12% APR fixed for 1-7 years.
3. Avalanche vs Snowball
Avalanche: sort by APR (highest first). Snowball: sort by balance (smallest first).
When to consider IVA, DRO, or bankruptcy
If DSR exceeds 60% and refinancing isn't possible, the UK offers legal frameworks:
Debt Management Plan (DMP)
Informal agreement via charity (StepChange, Citizens Advice). Free, voluntary. Doesn't affect credit but registered.
Individual Voluntary Arrangement (IVA)
Formal 5-6 year agreement with creditors. Requires Insolvency Practitioner. Stays on credit file 6 years.
Debt Relief Order (DRO)
For low-income, low-asset, low-debt situations (debt < £30,000). Cheaper than bankruptcy. Stays 6 years.
Bankruptcy
Discharges most debts. Stays on credit file 6 years. Costs ~£680 court fee.
NOT shameful — legal tools when situations are unsustainable.
