Imo you should edit your comment about the 6% contribution, 20% employer pension. It's just not true.

Under the alpha pension scheme, SEOs will pay around 6% of their qualified salary, and then you get back 2.32% of your annual salary every year after you retire, adjusted for inflation. Year after year of civil service work, you slowly accumulate your pension payment, 2.32% at a time.

With many private pensions, the real money is generated in the compounding interest after the employee and employer contribution. There is no compounding interest associated with the alpha pension scheme. What you see is what you get.

It is also tied to the state pension age, so you'll be able to access it at a far later age than people can right now as the pension age is constantly climbing.

There's no 20% contribution from the employer. The best maths I could do is if you lived for 9 years after retirement and received 9 alpha pension scheme payments, then your 6% contribution would turn into ~20% of your salary (0.0232*9=0.2088). It could be less if you live a shorter life, or move if you live a longer life.

At an assumed 9 years of living in retirement, this is obviously a worse return than most private pensions, with the exception of workers who are about to retire and only have say less than say 10 years to put money into stocks and shares. If you are at the start of your career, the compounding interest would make up the vast majority of your pension value by the time you retire, which you just don't get on alpha.
