The advisor wasn't sure but thinks not
I'm inclined to agree with your Financial Adviser.
The on-call hours
probably don't 'boost' service in that if your wife works a regular work week plus on call for a year, she will get one year service towards her pension.
That's how it works in other HSE roles that I am familiar with. Those who work on-call for a year don't get, for instance, 1.1 years of service (if that's what you are getting at?).
Where doing on-call could factor into her pension calculation is that it could increase her
'Pensionable Remuneration'.
It's probably the case that she is in a Final Salary Scheme so basic salary plus allowances will be factored into her pension calculation.
If one is in a Final Salary Scheme, one wants to get the 'service' and 'final remuneration' numbers as high as possible.
I know some, not all, on-call payments factor in to a medical consultants pension calculation, for instance.
As for your wife's service, she should also check to see if the role she works in is eligible for
Professional Added Years (PAYs) which could boost her service.
The pension department of your wife's employer will be best placed to advise if the on-call payment she is in receipt of is a pensionable emolument and any entitlement to PAYs . If she is, your Financial Adviser can factor these items in to any pension calculations/estimates they are completing for you. The pensions department of your wife's employer can also provide a pension estimate, but it may take a long time, as they tend to prioritise those right at the point of retirement.
I do recall reading somewhere that it does.
If you find out anything different to the above, please update the thread!
