Al-R, I know, I have one...and still felt well renumerated after I had a couple of years service under my belt.
Don't get me wrong here, I'm not knocking anyone...I'm just saying understand what you're getting and do the maths before you start hopping over the fence.
The old police pension is based on 1⁄60th of your average pensionable pay for each year of pensionable service up to 20 years, and 2⁄60ths of your average pensionable pay for each year over 20 years, up to a maximum of 40⁄60ths. Officers will pay 12.75% for this now.
The newer scheme, NPPS, is based on 1/70th of your final pensionable pay for each year of pensionable service up to a maximum of 35/70ths. Contributions of 10.5% by employee.
