We use a broker through our SM. We always get multiple quotes in a report from the broker. The report also lists those insurers who refused to quote. In our building the SC is authorised to spend up to $15k without an AGM Or SGM. So far our insurance has always been under this amount and the SC always proceeds with an insurer who meets our needs. The quoting process provides scrutiny. You should be able to ask the SM or SC for evidence of approaching the market to obtain the best quotes.
