I bought Travel Insurance for my 70 something Ma from Crotty Insurance in Sandyford, the first year there was a requirement for a Health Document to be completed from her Doctor and has been plain sailing for annual renewal since then. Hopefully they will be able to help you.

There are exemptions in the Equal Status Act. From here:
5. Exemptions on all grounds
The Acts allow people to be treated differently on any of the grounds in relation to:
Insurance - Covering annuities, pensions, insurance policies and other matters relating to risk assessments but only if the differences are based on actuarial or statistical data or other relevant underwriting or commercial factors and are reasonable having regard to the data or other relevant factors;
Basically, an insurer can charge different rates if they have the data to support the assertion that the older age category poses a greater risk.
