How the 73 Auto insurance estimate treats Somerset

73 Auto estimate, not a quote. Somerset's vehicle-crime index is 0.38 (its rate ÷ the national rate). The model floors the index at 0.5, so it treats Somerset like any other area at half the national rate or less. The collision part of the premium is multiplied by 0.52 (index^0.94) and the theft part by 0.50 (index^1).

Against the UK-average area (index 0.92), that makes the estimate for the reference driver (age 48, clean record, group 20 car) about 38% lower. The estimate uses your postcode district's index, listed below, not the authority figure directly. The area weighting was fitted to 7 published area premiums (leave-one-out error 13% against 19% with no area effect). See how 73 Auto estimates insurance.

Limitations

Police-recorded crime only: unreported offences are missing, and recording practice varies between forces.

The rate is per car registered to a keeper in Somerset, not per car on its streets. Where many commuters or visitors park, offences against their cars count here while the cars count elsewhere, which pushes the rate up.

Offences a police force did not assign to an area are shared across its areas by car numbers. Scotland and Northern Ireland are not covered.
