A low charges (e.g. 0% on each contribution and c. 1% annual management fee and no other charges other than, perhaps, a once off arrangement fee of a few hundred €) PRSA or personal pension plan (Retirement Annuity Contract/RAC) might be suitable. Given the timeframe to retirement consideration should be given to the most suitable/appropriate type of fund (e.g. possibly a medium risk/reward rather than anything with more volatility). The SSIA to PRSA transfer incentive is also certainly worth checking out if he and/or you qualify. If in doubt get independent, professional advice.
