Andy Burnham Cash ISA Rules: What Changes for UK Savers in 2027?

Searches for Andy Burnham cash ISA rules are mainly about whether people will still be able to put £20,000 a year into tax-free cash savings. The answer is changing from 6 April 2027.

For the 2026/27 tax year, an adult can still subscribe up to £20,000 across eligible ISAs and can put the full amount into cash if they wish.

From 6 April 2027, people below the age-based exemption will be limited to £12,000 of new Cash ISA subscriptions each tax year, while the overall adult ISA allowance remains £20,000.

Existing Cash ISA balances are not being cut to £12,000. The change applies to new annual subscriptions, not to money already protected inside an ISA.

For business owners, directors and sole traders, the main issue is how personally owned surplus cash is divided between tax-free cash savings, investments and taxable savings accounts.

Did Andy Burnham Introduce the Cash ISA Changes?

No. The reduction was announced before Andy Burnham became Prime Minister. His government inherited the policy and is now responsible for whether it remains unchanged.

That distinction matters because the change is no longer simply a political proposal. The regulations implementing the new limits were made in September 2026 and are scheduled to come into force on 6 April 2027.

The current position therefore should be treated as a confirmed future rule unless the government formally changes it.

What Are the Cash ISA Limits Before and After April 2027?

Rule	2026/27	From 6 April 2027 for those below the age exemption	From the qualifying age tax year
Overall adult ISA allowance	£20,000	£20,000	£20,000
Maximum new Cash ISA subscriptions	£20,000	£12,000	£20,000
Remaining overall ISA allowance after maximum cash subscription	£0	£8,000	£0
Existing Cash ISA balances capped at this level?	No	No	No

The remaining £8,000 is not a separate bonus. It is simply part of the existing £20,000 overall ISA allowance that cannot be placed into a Cash ISA by someone subject to the £12,000 limit.

When Does the £20,000 Cash ISA Limit Apply From Age 65?

The higher Cash ISA limit applies from the start of the tax year in which a person turns 65.

That means someone who turns 65 on 10 October 2027 can use the higher cash limit from 6 April 2027. Someone who turns 65 on 6 April 2028 would first qualify in the 2028/29 tax year.

State Pension status does not determine the allowance. The test is the relevant age rule, so a person does not need to be receiving the State Pension to qualify.

What Happens to Existing Cash ISA Savings?

Money already inside a Cash ISA does not have to be withdrawn simply because the annual cash subscription limit falls.

A saver with £75,000 already held in Cash ISAs on 5 April 2027 could keep that balance within the tax-free wrapper.

If that person is subject to the £12,000 limit, they could then add up to £12,000 of eligible new Cash ISA subscriptions during 2027/28, assuming they have not used that part of their allowance elsewhere.

Interest earned inside the Cash ISA does not use up the annual subscription allowance.

Care is needed when moving old ISA money. A formal ISA transfer is normally different from withdrawing money personally and paying it back in. Withdrawing first can affect the tax wrapper or use subscription room unless flexible ISA rules apply.

Can Someone Still Use More Than One Cash ISA?

Yes. A person can subscribe to more than one Cash ISA, provided their combined subscriptions stay within the relevant annual limit and each provider accepts the account.

Opening several accounts does not create several allowances. The limit applies to the person across their Cash ISA subscriptions.

Can Couples Put £24,000 Into Cash ISAs From April 2027?

Yes, if both partners are individually subject to the £12,000 limit and both have the full allowance available.

ISA allowances are individual rather than household allowances. Two eligible adults could therefore subscribe a combined £24,000 into Cash ISAs during the same tax year.

If one partner qualifies for the £20,000 age-based cash limit and the other is limited to £12,000, their combined potential Cash ISA subscriptions could be £32,000.

Will ISA Transfers Still Be Allowed?

Transfers will continue, but an important restriction starts in April 2027.

For people below the age exemption, transfers from Stocks and Shares ISAs or Innovative Finance ISAs into Cash ISAs will be restricted. Transfers from Cash ISAs into non-cash ISAs can still be made, and Cash ISA-to-Cash ISA transfers remain possible.

The restriction is removed from the qualifying age tax year.

What Is the 22% Charge on Cash Held in Non-Cash ISAs?

From April 2027, interest or an equivalent finance return paid on cash held inside a Stocks and Shares ISA or Innovative Finance ISA will face a flat-rate charge linked to the savings basic rate, currently set at 22% for 2027/28.

This does not mean the Cash ISA itself is taxed at 22%, and it is not a charge on the cash balance. It applies to the interest generated by cash sitting inside a non-cash ISA.

For example:

Example	Amount
Cash left uninvested	£8,000
Interest at an illustrative 4%	£320
22% charge on that interest	£70.40
Interest remaining after the charge	£249.60

The Personal Savings Allowance does not offset this specific charge.

Money market funds also face additional anti-circumvention rules. They can form part of an eligible investment portfolio, but a non-cash ISA cannot be structured so that 100% of its relevant investments are money market funds.

What Can Someone Do With the Remaining £8,000?

A person using the maximum £12,000 Cash ISA limit still has choices. They do not have to invest the remaining £8,000.

Possible options include:

• Investing some or all of it through a Stocks and Shares ISA
• Using an Innovative Finance ISA where suitable
• Using a Lifetime ISA if eligible and appropriate
• Keeping cash outside an ISA
• Leaving part of the annual ISA allowance unused

The right choice depends on risk, access needs and time horizon. Short-term emergency or business money should not automatically be moved into investments simply to use an allowance.

Someone keeping more money outside an ISA may also want to compare accessible savings products. A regular saver account example can help illustrate why headline interest rates need to be considered alongside monthly deposit limits and accessibility.

How Could the Lower Cash Limit Affect Tax on Savings?

The practical tax effect depends on how much interest a person earns outside ISAs and what tax-free savings allowances remain available.

Someone placing an additional £8,000 in a taxable savings account at 4% would earn £320 in annual interest. If that interest is fully covered by an available Personal Savings Allowance, there may be no extra tax.

If the allowance has already been used, tax could arise on the interest. From April 2027, planned savings income rates are 22% for the basic savings rate, 42% for the higher savings rate and 47% for the additional savings rate.

The effect therefore varies by household, depending mainly on taxable interest and available allowances.

How Could the £8,000 Difference Add Up Over Time?

If someone wants to save £20,000 a year entirely in cash, the £8,000 that can no longer go into a Cash ISA may instead sit in taxable savings.

Savings tax rate	Tax paid over 5 years	Estimated balance shortfall after 5 years	Tax paid over 10 years	Estimated balance shortfall after 10 years
22%	£1,101	£1,160	£4,258	£4,794
42%	£2,079	£2,192	£7,931	£8,938
47%	£2,321	£2,447	£8,821	£9,944

These are illustrations, not forecasts. Actual rates, balances, allowances and tax positions can change.

If savings figures appear unexpectedly in a PAYE code, it is sensible to compare the tax calculation with the actual account records and check whether an ISA tax-code error may be involved.

Do the New Rules Affect Households With £10,000 in Savings?

Not automatically.

A household having £10,000 in savings is different from an individual subscribing more than £12,000 of new money into Cash ISAs in one tax year.

Someone putting £10,000 into a Cash ISA during 2027/28 would remain below the new £12,000 cash subscription limit. Existing savings above £12,000 also do not have to be removed from a Cash ISA.

The rule becomes most relevant to people who regularly add more than £12,000 of new cash to ISAs each year.

What Do the Changes Mean for Directors and Business Owners?

A limited company cannot use a director’s personal ISA allowance. Company cash and personal savings should be kept separate.

A director must first receive money personally through an appropriate route, such as salary or a lawful dividend, before placing personal funds into an ISA. Paying a dividend and then putting the money into a Cash ISA does not remove any dividend tax already due.

The ISA protects future qualifying returns inside the wrapper. For business owners, liquidity should come before maximising an ISA allowance.

Money needed for VAT, Corporation Tax, wages, suppliers or near-term operating costs should remain available rather than being extracted simply to meet a 5 April deadline.

Sole traders should also separate accessible reserves from long-term savings. Some emergency cash may remain in ordinary savings accounts where immediate access matters more than tax efficiency.

Could the 28 October 2026 Budget Change the Cash ISA Rules?

The Autumn Budget is scheduled for 28 October 2026, so there is naturally speculation about whether the new government could revisit ISA policy.

As of 9 October 2026, there has been no official announcement cancelling the £12,000 Cash ISA limit, the transfer restriction or the charge on cash interest in non-cash ISAs.

Because the implementing regulations have already been made, savers should plan on the basis that the April 2027 rules will take effect unless a formal change is announced.

The Budget could still introduce new savings measures or change future policy. A separate first-time-buyer ISA is also being developed to replace the Lifetime ISA for new applicants once available, but that process does not itself cancel the Cash ISA reforms.

Rumours alone are not a reason to make a rushed investment decision.

What Should Savers Do Before 6 April 2027?

The 2026/27 tax year remains under the current rules. Anyone considering their position can use the following timeline:

Period	Practical Step
Before 28 October 2026	Review current ISA subscriptions and avoid acting solely on Budget rumours
After the Budget	Check whether any ISA policy has formally changed
Before 5 April 2027	Consider whether using available Cash ISA allowance fits personal cash needs
From 6 April 2027	Apply the new cash limit, age rule and transfer restrictions
During 2027/28	Track subscriptions across providers and review tax on non-ISA interest

Using an allowance should not override emergency-fund needs, debt priorities or investment risk.

Conclusion

The Andy Burnham cash ISA rules do not remove the £20,000 overall adult ISA allowance, but they change how much many savers can put into cash from 6 April 2027.

For people below the age exemption, the key figure is £12,000 of new Cash ISA subscriptions a year. Existing balances remain protected, couples retain separate allowances, and those reaching 65 qualify for the higher cash limit from the start of the relevant tax year.

The practical priority is to separate short-term liquidity from long-term investing and plan around confirmed rules rather than Budget speculation.
