Diamond's car insurance policy: is it good or bad?

We analyse and rate the 58 most important elements of standard car insurance policies to come up with the overall policy score. We assess how important each individual element is to drivers when choosing and using a car insurance policy, and weight it accordingly when calculating our total policy score. 

Initially, we score all of the product elements out of five, reflecting how competitive each provider is in this area compared with other insurers. Weightings are then applied to the higher and lower element scores to enhance/reduce their impact in the overall product score.

Table last updated in January 2019. Next update in January 2020.
