More than three-quarters of customers stay with their general insurers when policies are up for renewal, a new study reveals.

About 14% obtain quotes from another insurer but decide against switching, Roy Morgan Research’s survey of 10 insurance providers shows.

CGU has the most loyal customer base, with 85% renewing without approaching another insurer. It is followed by RACV Insurance (82.8%), Commonwealth (82.6%), RACQ Insurance (82.3%) and Suncorp-owned Apia (82.2%).

Suncorp Insurance places sixth (81.7%), followed by IAG-owned NRMA Insurance (79.6%), Allianz (74.9%), AAMI (72.7%) and GIO (69%).
