I am due to retire next summer and as I've been supply/part time teaching for the last 10 years I'm now looking at different ways in which I can boost my pension. I will take advice from Wesleyan when I get round to filling in the form, but for now can someone explain the advantages of taking out additional pension. I've been on the TPS website and used their calculator, which works out as a £4,900 lump sum to get an extra £250 per annum on to my pension. Would this be for a maximum of 20 years pay out? As I've said I need someone who is au fait with all this to explain it to me more fully. Thanks in anticipation.
