As an LGPS member, you build up a pension that will increase in line with the cost of living for the rest of your life after you take it. You can exchange part of your pension for a tax-free lump sum that is paid when you take your benefits.
You can only choose to swap pension for lump sum when you first take your LGPS pension. You cannot change your decision later. It is important that you think carefully and make the right decision for you.
