Motor insurance is provided as a private contract between the supplier and the customer. Individual motor insurance quotations are not a matter in which I would have any direct involvement or responsibility.
There is no legal provision to compel an insurance company to reveal the reason a quote was refused. However, I understand that, in practice, where a quote is refused or considered to be so exorbitant as being tantamount to a refusal, there is a Declined Cases Agreement in place, operated by the Irish Insurance Federation, whereby a quote can be secured. The Declined Cases Agreement exists to facilitate motorists meeting their obligation to have third party liability motor insurance.
