|---|---|---|
| 60+ days before | Slightly inflated | Too early |
| 21–28 days before | CHEAPEST prices ✓ | Sweet spot! |
| 7–14 days before | Prices creep up | +15% |
| Auto-renewal | HIGHEST prices | +£80–120 markup! |
Strategy 3: Voluntary Excess Sweet Spot
| Voluntary Excess | Annual Premium | Recommended? |
|---|---|---|
| £0 | £650 | No — overpaying |
| £100 | £580 | Good for most |
| £250 | £520 | ✅ Best balance |
| £500 | £490 | Only if savings available |
Strategy 4: Black Box for Under 25s (Save £300-600)
| Age | Standard Policy | Black Box Policy | Saving |
|---|---|---|---|
| 17–19 | £1,800–2,500 | £900–1,400 | £900–1,100 (50%) |
| 20–22 | £1,200–1,600 | £700–1,000 | £500–600 (40%) |

⚠️ Warning on Fronting: Naming a parent as main driver when you're the actual main driver is illegal and voids your insurance. The named driver must genuinely use the car sometimes.
