We have had Blue Sky through
Poliseek for the past two years. During that period we have had one minor at-fault claim which was handled well. Recently, I was involved in a minor accident for which the other driver was responsible, but which I had reported to Blue Sky in case I needed their help in getting it resolved. Again, I was very pleased by the professionalism of the person I worked with.
I believe Blue Sky achieves its low rates by being the kind of insurance company that "bundles" policies and sells them to other re-insurers. This is pretty common in the insurance industry so it is not something that should cause concern. I'm not 100% sure of this, but my Blue Sky card says that my insurance is through Companion Casualty, which, itself, is an arm of Blue Cross South.
However, I don't really care who pays the bills as long as the Claims phone number is answered by a competent and polite person who gets the job done. In both cases in which I contacted Blue Sky that has been the case.
