Who you are insured with? InsuranceHouse.
Are you as happy as can be ? Yes, with the caveat that having insured a number of aircraft for around 12 years I’ve never made a claim.
Would you recommend them? Yes, subject to the above caveat.
Any that you would not recommend? QBE via SAAA. The turf wars between SAAA and RA-Aus meant that despite being a SAAA member for >12 years, being a >500h GA pilot with numerous ratings and endorsements and building via the SAAA’s process of TC inspections using their risk radar, they would not insure my latest build because I chose to register it with RA-Aus. (I’m no longer a SAAA member.)
