How to Read an MOT History Report
Pass vs Fail
A pass means the car met the minimum legal standards on the test date. A fail means it did not. One or two failures over a car's lifetime is normal, especially for older vehicles. Multiple consecutive failures suggest poor maintenance.
Advisories (The Most Important Part)
Advisories are items the mechanic noticed but that have not yet deteriorated enough to fail the test. These are your crystal ball for future costs. Common advisories and what they mean:
| Advisory | What It Means | Typical Cost When It Fails |
| Brake disc worn but above limit | Brakes need replacing soon | £300-600 |
| Tyre tread depth approaching limit | New tyres needed soon | £60-150 per tyre |
| Suspension arm bush worn | Suspension component deteriorating | £150-400 |
| Slight oil leak | Engine seal wearing, monitor | £100-500 depending on source |
| Exhaust corroded | Exhaust may need replacing | £150-500 |
| Anti-roll bar linkage worn | Suspension component | £80-200 |
CarCostCheck automatically calculates the estimated cost of all current advisories, so you do not need to research each one individually.

Mileage Readings
Every MOT records the odometer reading. In a genuine car, mileage increases steadily at roughly 8,000-12,000 miles per year for an average driver. CarCostCheck plots these on a graph, making anomalies obvious:
- Mileage drops between tests: The odometer has been wound back (clocking). This is fraud.
- Flat mileage for years: The car was barely driven (possible, but unusual) or clocked before the most recent test.
- Sudden large increase: May indicate heavy use in one year, or a previous clock followed by genuine use.
Red Flags in MOT History
- Structural advisories or failures: Corrosion to structural components, chassis damage, or subframe issues. These are expensive and can indicate the car is reaching end of life.
- Recurring failures: The same item failing repeatedly suggests a systemic problem that quick fixes are not solving.
- Long gaps between tests: If the car went several years without an MOT, it was either off the road (SORN) or driven illegally. Either raises questions.
- Brake system warnings: Brake binding, fluid leaks, or servo failure advisories are safety-critical.
