Wiltshire Pension Fund has signed up to Club Vita but is yet to find out how its contribution figures correspond to its members’ longevity projections.
Scheme head David Broome said: “There are so many assumptions involved in valuing pension-fund contributions that anything that offers a degree of certainty is very, very welcome.
“The more the valuation of the Local Government Pension Scheme is backed by facts the better.
“I can look the pensions committee in the eye and say we have built into our contribution assumptions longevity data that is relevant to this area that is right down to the postcodes.”
The Wiltshire fund covers staff from around 60 different bodies and currently has 19,000 active members, 10,000 pensioners and around 15,000 deferred members.
Mr Broome expects the data to suggest possible contribution reductions of between 1% and 4%, and is cautiously erring towards the lower end of the scale.
He accepts that potential savings from the refined longevity data is unlikely to counteract the expected deficits across funds that will come into view from next year’s valuation.
“It will help around the edges, but it won’t work a miracle,” he said.
