THE ACTUARY LENS
When does mileage improve motor insurance pricing?
Mileage improves the exposure denominator. For high-intensity books, time, road, purpose and occupancy determine the risk carried by each mile.
The product directory now distinguishes availability, source evidence, scale and financial outcomes. Products and downloads use the release shown below.
MOT evidence record: 19 Sept 2026. 1,268,479 vehicles matched across December 2024–December 2025.

Availability, source evidence, commercial scale and profitability answer different questions. An acquisition, run-off or customer saving does not establish underwriting profitability.

Base risk + miles driven × risk intensity
STATS19 is road-safety evidence, not insurer claims experience. Aggregate comparisons can support segmentation tests; they do not establish causality.
RISK CONTEXT
Great Britain · 2023–2025. Police-reported injury collisions and traffic exposure; these are not insurer claim rates.
2023–2025 · Great Britain · all hours = 1.00
Higher collision-to-flow index in each year
Higher collision-to-flow index in each year

Below-average index in each year
Collision share ÷ traffic-flow share, calculated independently for each year. Indicative exposure signal; not an insurance claim rate.
Derived · 2023–2025 · Great Britain
Relative exposure signal; not an insurer claim rate or a direct per-mile estimate.
MOT EVIDENCE LAB
Great Britain · December 2024–December 2025. Official DVSA anonymised test results, using the latest normal test per vehicle.
December 2024–December 2025 · 1,268,479 matched vehicles
There is a 7.9× difference between the 90th and 10th percentiles of annualised mileage in this cohort.
Derived from odometer change, annualised for test intervals of 300–430 days. Normal tests only; latest test per vehicle; 100–100,000 plausible annual miles retained.
Derived · December 2024–December 2025 · Great Britain
December cohort only. Test interval restricted to 300–430 days and plausible annual mileage to 100–100,000 miles.
Derived · December 2024 and December 2025 · Great Britain
Lifetime annualised mileage is a repeatability check. Broad MOT classes cannot isolate taxi, small van or people-carrier use without further classification.
The postcode area identifies the test station—not the keeper. Rural, city and transport-access comparisons require validation.
