Aviva having takent over from UK, I have just had to renew my upgrades. Last year Uk charged £250.94 for 3 minor medical, 90 day extention and being over 70. Aviava boast that they have no age limit, so I had only to renew the first 2. Imagine my shock when they quoted £488.80, the 90 day extension was over £300! Having complained to Nationwide, they are looking into it but Aviva maintain that these are fair charges. As I can get a complete package from another insurer for more than £100 less, I have told them where to stick it. So far thier last response was to send a leaflet for complaints to the Ombudsman. So if you use this service and need upgrades, beware!
