Is it still worth buying additional pension from the TP scheme, blocks of £250 it says, when i retire in the summer of 2019 aged 60 on a final salary system? I am already buying back 6 added years by the old system, from 2002. I have 35 years of teaching in the service. I realise that the new option is not as good as the old one. So what I was wondering is there any financial benefit in doing this as opposed to just saving for the next few months? I intend to take my maximum lump sum next summer to gain the tax free benefits.
