^fragalino Thanks.
I know it partly comes from jealousy. All my friends who work for private firms are now all talking about retiring at 50. Most are in better health than me and talking about how they will enjoy their time when they retire. Some of their plans are being funded through company pensions, some through inheritance.^
I think this is where you are getting confused.
This won't be to do with their pension scheme, as, generally, the LGPS IS better. I am guessing it is because they are higher earners than you.
You can retire earlier if you want as well. And the penalty is the actuarial reduction. When your friends retire early, the penalty is the fact that they will have made contributions for less years, which will result in less money.
So they are also being penalised.
Your reference to "funded through company pensions" suggests they are getting something you are not. As above; they aren't. Simply put, the LGPS says "look, this is what you could have if you work until age XX. You want to retire early, ok, so it'll be less, it'll be £xx". Private companies on the other hand, don't offer you any guarantee of how much you'll get in retirement. It's not their retirement and they're not interested. They say "ok, here's x amount per month that we'll pay into your pension pot each month. You can pay some in too. Depending on investment performance it might be worth £x at age 67. You want to retire early? Fine, it'll obviously be much less then."
I really think you need some proper financial advice.
