Employees will be able to save for their pension in Dutch-style collective funds, under plans unveiled by the government this week.
The changes, which could be introduced by 2016, would allow workers to pay into funds with thousands of others, pooling their risk and theoretically lowering the costs associated with the fund thus giving a higher return.
Ministers say the move to collective defined contribution (CDC) schemes could give better value than current defined contribution schemes, though returns cannot be guaranteed.
Will Aitken, senior consultant at Tower Watson, added that the move wasn't necessarily about improving pension pots but creating more stable outcomes. "Collective Defined Contribution is sometimes presented as a magic wand that can make everyone better off in retirement but the government has never been convinced of that," he said.
"Instead, it hopes that it can make pensions less of a lottery, rather than making them bigger on average."
The Private Pensions Bill was one of two pension bills unveiled during the Queen's Speech at the State Opening of Parliament.
The other, the Pensions Tax Bill, will implement reforms to annuities announced in Chancellor George Osborne's Budget in March, which allow people to draw their retirement income out in one go if they so choose.
The change will mean no-one with a defined contribution pension will have to buy an annuity, which would guarantee an income for life, with their pension pot.
The moves have received a mixed response from industry experts, with some praising the greater choice available to those approaching retirement age, with others unhappy with the raft and speed of changes the government is introducing.
Alan Hingham, head of retirement insight at Fidelity Worldwide Investment, said: "Fidelity is concerned that the sheer volume of new pension legislation – albeit well intentioned – is having a detrimental impact on consumers. We welcome the changes announced in the Budget and with the right support they should enable consumers to enjoy a much better retirement."
He added: "Customers we speak to are totally confused by their choices which leads to paralysis of action which benefits few."
With such a huge amount of changes to take in, financial advice network unbiased.co.uk said it is vital consumers get the correct information to make the right choice about their retirement.
"It's vital for consumers to have confidence that they are choosing the right option for them and it is even more important that they know where they can go to get help in making these decisions," a spokesperson said.
"Our latest research asked people about their retirement plans and only 38% said they were 'confident', while a quarter (25%) said they were 'anxious'.
The Queen's Speech also announced the Childcare Payments Bill, which will create a new tax-free subsidy for parents worth up to £2,000 a year and will be available from Autumn 2015.
The subsidy will be available to all parents who earn less than £150,000 a year and have children under the age of 12.
