I opted out of SERPS about 15 years ago and have about 25 years to go untilI retire. With the political pressure from the ageing population (by 2030) and probable poor performance from private/flexible pensions, there must surely be an argument for opting back in. Appreciate peoples thoughts.

My wife has just had a leaflet from her pension company about just this issue. Best use for it is to start a fire. After reading it I was lead to the conclusion that whether to opt back in or staying opted out is equivalent to choosing red or black, except in your case the roulette wheel will take twenty five years to spin (up to 6 Governments, any one of which can change policy). You may be better off, you may not and as no one can forsee the future it will be luck whether you choose correctly or not - remember endowments?!!
