The Ombudsman received a total of 19 complaints about Irish Life Assurance, six of which were fully upheld.
It was followed by Irish Life Health on seven complaints and Permanent TSB on six complaints.
Both Irish Life Assurance and Irish Life Health are owned by the Great West LifeCo Group.
The Financial Services Ombudsman's Overview of Complaints for 2018 reveals that the office received a total of 5,588 complaints last year.
56% of these related to banking products, with mortgage complaints accounting for 32% of all such grievances last year.
33% of complaints were about insurance products, while 6% related to pension schemes and 5% were about investment products.
The Financial Services Ombudsman said a total of 4,443 complaints were resolved last year.
Of these, 2,331 complaints were resolved through the office's informal mediation process with 1,219 getting redress and/or compensation.
– Payment of €223,463 in relation to a claim under a serious illness policy which had initially been rejected
– Payment of €122,500 to a family whose claim in relation to their father's whole of life policy had been rejected

– Compensation of €1,500 to a couple from a mortgage provider in relation to a delay in providing their house deeds
– Refund of AVCs paid, and compensation of €1,000 due to incorrect advice provided by a pension scheme administrator.
The Ombudsman also said that 234 legally binding decisions were issued following adjudication and of these, 127 were fully, substantially or partially upheld.
Financial Services Ombudsman Ger Deering said he regretted to see that insurance companies continue to void policies in a manner which he considered to be "unreasonable and disproportionate".
"Where a person has an insurance policy cancelled by an insurance company due to alleged non-disclosure, or for whatever reason, this can have serious implications and render it very difficult, and in some instances almost impossible, for that person to get any sort of insurance cover subsequently," Mr Deering said.
He said he firmly believes the voiding of an insurance policy is something that should not be done lightly.
"To avoid the risk of non-disclosure and the potential voiding of policies, I hold the view that insurance companies and insurance intermediaries should ask questions prior to the inception of a policy in a clear manner and ensure that customers are clear on what they are being asked and the potential consequences of answering incorrectly," he added.
Mr Deering also said the large volume of complaints received by his office resulted in a longer than wished for processing time.
But he welcomed the recent confirmation by the Minister for Finance that an additional 35 positions will be added to the office.
He said this will greatly assist it to keep pace with the speed of change, to eradicate waiting times to have complaints resolved, and to achieve the objectives set out in its Strategic Plan.
The Ombudsman also welcomed the fact that the vast majority of complaints were resolved through the informal mediation process as this provides a faster outcome that is acceptable to both parties involved.
