Strong growth of motor and household sales made up for weak life results at the Co-operative Insurance Society.

The society made a pre-tax loss of £254.1m for 2001, a deterioration from a £49.6m loss the previous year.

General insurance premium income increased to £599.4m in 2001 from £457.7m in 2000. Of this, its motor book and other business saw premiums rise to £405.3m from £273.5m.

The society is to develop products and services with environmental benefits.

Examples include giving policyholders cheaper premiums in return for considering the environmental impact when they claim for a new fridge.
