Underperforming pension funds will be barred from winning new business under a crackdown to be announced by Jeremy Hunt in the Budget.

The Chancellor will use his March 6 statement to outline plans to block poorly performing funds from taking on new business from workplace pension schemes.

Funds will also be forced to disclose how much of savers’ money is invested in Britain to drive more domestic investment.

Mr Hunt wants to boost returns for savers while directing more cash towards productive, higher-returning assets under plans first announced in last year’s Mansion House speech.

Additionally, the Chancellor will use the Budget to hand entrepreneurs a boost following an outcry over changes to Britain’s angel investor scheme.

The Treasury faced a backlash after raising the income threshold used to define so-called high net-worth individuals from £100,000 to £170,000 this year, cutting off investment ownership protections for thousands of angel investors.

The Telegraph understands that the previous thresholds of £100,000 for income, or £250,000 for net assets, will be reinstated.

Campaigners said women were disproportionately affected because many did not meet the higher-income thresholds.

Mr Hunt will also make it easier for unlisted firms such as theatre production companies to raise cash from entrepreneurs.

The pensions performance clampdown, which will follow a similar system in Australia, will see new powers handed to regulators that could spark a wave of scheme mergers.

A consultation on handing more powers to the City watchdog and the Pensions Regulator will be launched by the Financial Conduct Authority (FCA) in the spring.

However, most changes will not be made until the next parliament because the shake-up needs parliamentary approval.

Mr Hunt said the transparency drive would mean employers and savers “can see how their money is invested and how the returns compare to other schemes.”

Current rules are inconsistent and do not require funds to disclose detailed information about British investments. The overhaul would apply to so-called defined contribution (DC) schemes, where returns depend on stock market performance instead of salary averages.

The Treasury wants DC pension funds to disclose their levels of investment in British businesses, as well as their costs and net investment returns by 2027.

Mr Hunt said: “British pension funds appear to contribute less to the UK economy than international counterparts do as they invest less in our domestic businesses. These requirements will help focus minds on how to improve overall returns and outcomes for savers.”
