Anyone who has not reviewed their cover in more than three years needs to act now to get better value, according to Dermot Goode of Healthinsurancesavings.ie.
He also advised putting the children on different plans to the adults to save money.
Here is a selection of good value plans for two adults and two children, aged between two and eight.
Laya Healthcare: Essential Connect Family costs €800 per adult, and €150 per child.
The total family cost is €1,900, but there is an additional 3pc charge if you pay by direct debit. This is a good mid-level plan, but it has limited cover in hi-tech hospitals.
There is a €300 excess on private hospital admissions for the first claim only.
Aviva Health: Mr Goode recommends the Health Value Plan, which is €850 per adult and is a good mid-level plan. There is a €125 excess for the first five nights of any private hospital admission.
He advises putting the eight-year-old child on Family Focus at a cost of €150. This includes payments for three GP visits at €30 each. Level 2 Family Health is recommended for the two-year-old at a cost of €233.
The total cost for the family will be €2,083.
GloHealth: The Better Plan is recommended by Mr Goode for adults at €908 each, and €238 for the eight-year-old. The two-year-old gets free cover from Glo.
This is a decent mid-level plan. There is a €50 excess for day-case procedures, and a €100 excess for overnight admission to private hospitals. The total cost to the family will be €2,053.
Vhi Healthcare: The corporate plan called Company Plan is recommended. This will cost the adults €943 each and is a reasonable mid-level plan.
There is a €75 excess for all admissions to private hospitals. For the children, the best option is Parent & Kids at a cost of €131 each. The total cost to the family will be €2,148.
