Cash ISA Changes on the Cards as Andy Burnham Could “Scrap” Policy, Says Expert

Millions of British savers could be handed an unexpected reprieve as Andy Burnham’s new Labour Government considers whether to abandon controversial plans to cut the amount people can place into a Cash ISA.

The policy, originally announced under the previous government, is scheduled to take effect in April 2027. Under the existing plans, people aged under 65 will be restricted to putting £12,000 a year into a Cash ISA, compared with the current £20,000 overall ISA allowance. The remaining £8,000 could still be invested through other types of ISA, including Stocks and Shares ISAs.

But the arrival of Burnham and Chancellor John Healey has thrown the future of the policy into doubt.

Financial experts believe the new government could decide to reverse the restriction altogether, potentially restoring the full £20,000 Cash ISA allowance.

For millions of cautious savers, that could represent a major change.

A major ISA decision is looming

The Cash ISA has long been one of Britain’s most popular savings products.

Its appeal is simple.

People can save money in cash while receiving interest without paying income tax on that interest inside the ISA wrapper. For savers who dislike investment risk, the product provides a straightforward way of building up a financial cushion.

But the previous government wanted to encourage more people to invest their money rather than leave it in cash.

The decision to reduce the Cash ISA allowance was therefore intended to change people’s behaviour.

From April 2027, under the existing rules, those aged under 65 will still have a £20,000 annual ISA allowance, but only £12,000 of that can be placed into a Cash ISA. The remainder would need to go into other eligible investments if the saver wants to use the full allowance.

The policy was designed as a nudge towards investing.

However, it has attracted criticism from parts of the financial-services industry, which argue that forcing cautious savers towards investments could discourage saving rather than encourage responsible investing.

Burnham could reverse the decision

That is where the new government comes in.

Morningstar reports that Healey could revisit the policy and potentially scrap the planned reduction, restoring the full Cash ISA allowance. The publication notes that experts see the Autumn Budget as an important moment when the new government could reveal its position on ISAs and wider personal-finance policy.

There is, however, no confirmed decision from Burnham to scrap the policy.

That distinction is important.

At present, the idea remains speculation rather than a government announcement.

The new administration inherited a large number of financial-policy commitments and is now reviewing them as it prepares its first major Budget.

The Cash ISA restriction is therefore one of several measures that could be reconsidered.

Why the policy was introduced

The argument behind the original restriction is relatively straightforward.

Britons have historically held enormous amounts of money in cash deposits.

While cash provides security, it does not directly provide capital to companies in the same way that investments in shares and funds can.

The Government therefore wanted to encourage more households to move some of their savings into investments.

The theory is that if more British households become investors, more capital could ultimately flow into businesses and productive assets.

This could support economic growth.

But there is an obvious problem.

Not every saver is an investor.

Someone saving for a house deposit in two or three years may reasonably prefer cash because they cannot afford to see their savings fall sharply during a stock-market downturn.

Likewise, older savers or people with limited financial experience may be uncomfortable taking investment risk.

Critics therefore argue that the Government should not treat cash saving as inherently undesirable.

The £12,000 limit could hit cautious savers

The planned restriction is particularly significant for people who regularly save large amounts.

Imagine someone capable of putting aside £20,000 each year.

Under the existing system, they could place the entire amount within an ISA, subject to the relevant rules.

Under the planned 2027 system, a saver under 65 could put only £12,000 into a Cash ISA.

They would have to decide what to do with the remaining £8,000.

They could invest it.

They could use another tax-efficient product.

Or they could simply leave it in an ordinary savings account, where interest above the applicable Personal Savings Allowance could potentially become taxable.

For a cautious saver, none of these options is necessarily attractive.

This is why financial experts have questioned whether the policy will actually produce the behavioural change ministers want.

Stocks and Shares ISAs are also changing

The Cash ISA restriction is not the only change coming.

The Government has also introduced measures designed to prevent people from simply moving cash into a Stocks and Shares ISA to get around the new £12,000 limit.

From April 2027, interest on cash held within Stocks and Shares ISAs will face a 22% tax charge, according to current rules. There are also specific provisions concerning “cash-like” investments and money-market funds.

That means savers will have to pay much closer attention to how their ISA is structured.

For many people, this could make the traditionally simple ISA system significantly more complicated.

Rachael Griffin, a tax and financial-planning expert at Quilter, has argued that although encouraging investment is a legitimate objective, the ISA system works best when it remains simple and easy to understand.

That criticism could become increasingly important if the Burnham Government decides to review the policy.

Experts divided over the future

There is no universal agreement about what Burnham should do.

Some experts believe restoring the £20,000 Cash ISA allowance would be sensible because it would preserve consumer choice and prevent the Government from effectively forcing cautious savers towards riskier assets.

Others argue that the restriction is necessary if Britain wants to change its long-standing culture of cash saving.

The Investment Association, which represents the investment-management industry, has strongly focused on encouraging greater investment and has published work examining how the ISA system could be used to turn savers into investors.

The debate therefore reflects a much larger question about Britain’s economic strategy.

Should government actively encourage people to invest?

Or should individuals be allowed to choose how much risk they want to take with their own money?

The Autumn Budget could provide the answer

The most important date may be October 28.

That is when Chancellor John Healey is due to deliver the Autumn Budget, according to Morningstar’s analysis.

The Budget will be the first major opportunity for Burnham’s government to demonstrate how its political promises will be financed.

That makes ISA policy particularly interesting.

A decision to restore the £20,000 Cash ISA limit would be popular with many cautious savers, but it would also represent a retreat from the previous government’s attempt to encourage greater investment.

Keeping the £12,000 limit would maintain continuity but could expose Labour to criticism from savers and parts of the financial industry.

Burnham therefore has a political choice to make.

There could be a wider ISA shake-up

The Cash ISA allowance is not the only possible change under discussion.

Morningstar has reported that the new government could also consider a lifetime cap on ISA savings or even revive the idea of a British ISA designed to encourage investment in UK companies.

A lifetime ISA cap would be particularly controversial.

There are more than 5,000 people estimated to have ISA holdings worth at least £1 million, according to HMRC figures cited by Morningstar.

From the Government’s perspective, wealthy ISA holders could represent a potential source of additional tax revenue.

But changing the rules retrospectively or imposing a lifetime limit could undermine confidence in the ISA system.

Savers need to believe that the rules surrounding long-term tax-efficient accounts will remain reasonably stable.

The “British ISA” could return

Another intriguing possibility is the revival of the British ISA.

The concept was originally proposed under Conservative Chancellor Jeremy Hunt as a way of encouraging British households to invest more directly in UK companies.

The previous Labour government abandoned the proposal after taking office.

But Andy Haldane, the former Bank of England chief economist and an adviser to Burnham’s Government, has subsequently argued that a domestic-investment bias could help address Britain’s weak “home bias” in household investment.

A revived British ISA could therefore become part of a broader attempt by Burnham to increase investment in the UK economy.

That would represent a significant shift in emphasis.

Instead of simply encouraging people to invest, the Government could attempt to influence where their investments go.

Why Burnham may be reluctant to make big changes

Despite the speculation, there are reasons for Burnham to proceed cautiously.

Personal-finance rules affect millions of people.

Frequent changes create confusion.

And every new restriction creates the possibility of unintended consequences.

Morningstar’s Michael Diamantopoulos argues that the Government has limited room for sweeping personal-finance changes given its wider political commitments and fiscal constraints. He suggests that Burnham’s Government may prefer policies with significant political symbolism but limited fiscal cost.

That could make the Cash ISA issue particularly attractive.

Restoring the allowance would be highly visible.

But it would not necessarily require a huge increase in government spending.

The political calculation could therefore be tempting.

What savers should do now

For savers, the most important point is that the £12,000 restriction has not yet taken effect.

The current rules remain in place until the planned April 2027 changes.

Financial guidance from Hargreaves Lansdown notes that under the planned rules, people under 65 will have until April 5, 2027, to make use of the current ability to put up to £20,000 into Cash ISAs.

That means savers should not make major financial decisions based purely on speculation about what Burnham might announce.

The Government could retain the policy.

It could amend it.

Or it could scrap it.

Until ministers formally announce a change, the scheduled rules remain the relevant framework.

A political gift for Labour?

There is an interesting political dimension to the debate.

Burnham has sought to position himself as a Prime Minister who understands everyday financial pressures.

Restoring the £20,000 Cash ISA allowance would allow Labour to portray itself as protecting ordinary savers.

It could be particularly attractive to households that have no desire to become stock-market investors.

But Labour would need to explain why it had reversed a policy specifically designed to encourage investment.

That contradiction could be exploited by critics.

Reform UK could argue that Burnham is abandoning efforts to improve Britain’s investment culture.

The Conservatives could claim that Labour is simply reversing policies without offering a coherent alternative.

The Government would therefore need a clear economic justification.

Conclusion

The future of the Cash ISA has suddenly become much less certain.

Under the existing timetable, the annual Cash ISA limit for people under 65 is due to fall from £20,000 to £12,000 in April 2027, while the overall ISA allowance remains £20,000.

But experts believe Andy Burnham and Chancellor John Healey could reconsider the decision.

Restoring the full £20,000 allowance would be welcomed by many cautious savers and would simplify the system.

Keeping the £12,000 limit would preserve the previous government’s strategy of nudging households towards investment.

There are also more ambitious possibilities, including an ISA savings cap or the revival of a British ISA.

For now, however, savers should treat claims that Burnham will “scrap” the Cash ISA changes as speculation rather than confirmed government policy.

The real answer is likely to come with the Autumn Budget.

And when it does, millions of British savers will be watching closely.

For Cash ISA holders, the £20,000 allowance may not be gone for good — but until the Chancellor confirms a reversal, the planned £12,000 limit remains firmly on the table.
