The retirement age of 60 was introduced in the new firefighters pension scheme 2006—a scheme that the shadow fire Minister, Lyn Brown, helped to introduce as Parliamentary Private Secretary to the then Minister, and the same age that Lord Hutton said should apply to members of the armed forces and the police. It is, however, well below the retirement age set for most public sector workers, recognising the unique nature of the occupation. Lord Hutton also proposed actuarially fair early retirement terms, and that pensions should be calculated on a career average arrangement. He found that the firefighters pension scheme 1992 is the most expensive public service pension scheme, at 37.5% of pensionable pay. Currently, for every £1 a firefighter pays into the scheme, the taxpayer pays an extra £5.
