The appointment comes in the week that the Government published a bill outlining the planned changes.
Under government plans, the state pension age for men and women will rise to 68 by 2050. The link between earnings and the basic state pension would also be restored.
Although NAPF broadly supports the plans, it said that it wants to reduce their ‘complexity'.
Under NAPF's proposals the two current state pensions - the Basic State Pension and the State Second Pension - would merge into a single payment that is easier for the public to understand and budget for.
Penrose steps in to partially fill the void left by the exit of NAPF head of press and PR Jane Dawson, who has recently gone on sick leave.
Agency partner Ben Curson heads the account, working with account director - and former NAPF head of press and PR - Andy Fleming and account manager Clare Milton.
‘This is a critical time for the pensions community,' said NAPF chief executive Joanne Segars, to whom the Penrose team reports.
NAPF is the most vocal lobby group on pensions. Approximately ten million working people in the UK are enrolled in private pension schemes run by NAPF company members.
