Help To Buy ISA Vs Lifetime ISA: Key Differences, Bonus Limits, Rules, And 2028 Reforms

There’s one fact that settles the Help to Buy ISA vs Lifetime ISA debate: the Help to Buy ISA closed to new applicants in November 2019, so the Lifetime ISA is now the only account still offering a 25% government bonus toward a first home deposit for new savers in 2026.

Key takeaways

• The Help to Buy ISA closed to new applicants on 30 November 2019, though existing savers can contribute until 30 November 2029.
• The Lifetime ISA pays up to £1,000 a year in government bonus on £4,000 saved and stays open to UK residents aged 18 to 39.
• HM Treasury confirmed on 23 June 2026 that a new First Time Buyer ISA will replace the Lifetime ISA from April 2028, without a withdrawal penalty.

What’s the Real Difference Between a Help to Buy ISA and a Lifetime ISA?

A Help to Buy ISA and a Lifetime ISA differ mainly in contribution limits and bonus timing. Both still offer a 25% government bonus in 2026, but the figures diverge once you look closer.

Help to Buy ISA rules last changed when the scheme closed to new applicants in 2019, while Lifetime ISA terms remain open. Here’s how the two compare.

These limits sit inside the wider £20,000 annual ISA allowance, covering cash ISAs, stocks and shares ISAs, and Lifetime ISAs combined. Proposed cash ISA allowance reduction plans, currently under review, could shrink the room left for Lifetime ISA saving once other accounts are funded.

Figures above reflect the rates GOV.UK confirmed as of August 2026, and may change once the First Time Buyer ISA consultation concludes.

Which Is Better, a Help to Buy ISA or a Lifetime ISA?

For most first time buyers in 2026, the Lifetime ISA offers the stronger bonus. A Help to Buy ISA caps out at £3,000 total, regardless of how long someone keeps saving.

A Lifetime ISA saver contributing the full £4,000 allowance for four years collects up to £4,000 in bonuses over that period alone, well past the Help to Buy ISA’s lifetime cap.

The decision usually rests on three factors: how much someone can save each year, when the bonus needs to arrive, and how expensive the target property is.

Buying outside London for under £250,000 still works with either account, but a property between £250,000 and £450,000 needs the Lifetime ISA, since the Help to Buy ISA bonus does not apply above its lower price cap.

Timing matters too: a Lifetime ISA bonus arrives monthly and can go straight toward the mortgage deposit, while the Help to Buy ISA bonus only appears once the sale completes.

Martin Lewis has repeatedly pointed savers toward the Lifetime ISA over the Help to Buy ISA for this reason, given its larger and faster bonus.

Is the Lifetime ISA Being Replaced? The First Time Buyer ISA Explained

Yes, the Lifetime ISA is being replaced. HM Treasury confirmed on 23 June 2026 that a new First Time Buyer ISA will launch in April 2028, aimed solely at first home buyers rather than covering retirement saving as well.

The reform follows years of criticism over the Lifetime ISA penalty. The Treasury Committee reported in 2025 that savers withdrawing for reasons other than a first home purchase lose 6.25% of their own money, not just the bonus.

The £450,000 price cap has also stayed frozen since the scheme launched in 2017, shutting out buyers in higher cost areas including much of London.

Under the proposed First Time Buyer ISA, several changes stand out:

1. The withdrawal penalty is scrapped entirely, since the bonus would only be paid once a qualifying property purchase completes.
2. There is no upper age limit for opening an account, unlike the Lifetime ISA’s cutoff at age 39.
3. It covers first home purchases only, with no retirement saving option.
4. The property price cap is expected to match the current £450,000 limit, though this has not been confirmed.

Some savers assume existing Lifetime ISA holders will be forced to close their accounts once the new product launches.

That’s not the case: savers can keep contributing and earning the bonus with no cut-off date, even once the First Time Buyer ISA becomes available. The reform builds on proposals first floated in the Rachel Reeves cash ISA changes announced in the 2025 Budget.

Who’s Eligible for a Help to Buy ISA or a Lifetime ISA?

Nobody can open a new Help to Buy ISA in 2026, since current Help to Buy ISA rules closed the scheme to applicants in November 2019. A Lifetime ISA can be opened by any UK resident from age 18, provided they have not yet turned 40.

Both are still, fundamentally, first time buyer savings accounts, though only one still accepts new savers.

Many savings guides describe Lifetime ISA eligibility as running from age 18 to 40, but that’s slightly off. An account must be opened before the saver’s 40th birthday, which means 39 is the last age at which someone can open one, not 40.

Couples buying together do not need to choose one account between them. Each partner can open a separate Lifetime ISA, save independently, and combine both sets of bonuses toward one shared first home purchase, provided both meet the first time buyer definition individually.

Cash or Stocks and Shares: Which Lifetime ISA Suits You?

A Lifetime ISA can hold cash or stocks and shares, and the right choice depends on the saving timeframe. The Help to Buy ISA never offered this choice, since it was only ever available as a cash account.

• Cash Lifetime ISA: Suits savers within one to five years of buying, since the balance cannot fall in value.
• Stocks and shares Lifetime ISA: Suits savers with a longer runway of five years or more, since returns can outpace cash but carry investment risk.
• Tax treatment: Growth in both versions sits outside income tax and capital gains tax under the same tax free savings rules HMRC applies to other ISA types, a point covered further in this guide to stocks and shares ISA tax.
• Providers: Firms such as Skipton Building Society offer cash Lifetime ISAs, and all providers, cash or investment, must be regulated by the Financial Conduct Authority.

Anyone unsure which suits them should weigh up how soon the deposit is needed against how much investment risk they’re comfortable with.

Can You Have a Help to Buy ISA and a Lifetime ISA at the Same Time?

Yes, holding both accounts at once is allowed. The restriction applies to the bonus, not the accounts: only one government bonus can be claimed when buying a first home, even with both open. According to MoneyHelper, this rule applies regardless of which account holds the larger balance.

Both accounts count toward the overall £20,000 ISA allowance alongside cash ISAs and stocks and shares ISAs, since UK savers can spread contributions across several ISA types in one tax year.

Readers weighing up how many ISAs can I have across their full portfolio should note that only one Lifetime ISA can be funded per tax year.

Many savers holding both eventually complete a Help to Buy ISA to Lifetime ISA transfer rather than running two accounts long term.

How Do You Transfer a Help to Buy ISA Into a Lifetime ISA?

The transfer process itself is simple enough, though each provider sets its own rules for accepting a Help to Buy ISA balance.

1. Contact a Lifetime ISA provider that accepts transfers in from a Help to Buy ISA, since not every provider offers this.
2. Complete that provider’s transfer request form rather than withdrawing the Help to Buy ISA balance directly.
3. Confirm how much of the transferred amount will count toward the £4,000 annual Lifetime ISA limit for the current tax year.
4. Wait for the funds to move directly between providers, since a personal withdrawal triggers the 25% penalty instead.
5. Check the Lifetime ISA has been open for 12 months before relying on it for a house purchase, since the waiting period restarts on transfer.

Anyone transferring a balance above £4,000 in one go needs to plan the move across more than one tax year to avoid breaching the annual limit.

What Happens If You Withdraw From a Lifetime ISA Early?

A 25% government charge applies to most early withdrawals. This claws back not just the bonus but a slice of the saver’s own contributions too, which is why the Treasury Committee flagged it as a source of consumer harm.

Three situations avoid the penalty entirely:

• Buying a first home worth £450,000 or less, provided the account has been open for at least 12 months.
• Reaching age 60, at which point funds can be withdrawn freely for any purpose.
• Being diagnosed with a terminal illness with a life expectancy under 12 months.

Someone who saves £1,000 and receives a £250 bonus ends up with £937.50 after a 25% withdrawal charge, losing money compared with simply not saving in a Lifetime ISA at all.

This penalty, and the proposed reform that would scrap it under the First Time Buyer ISA, is why so many financial commentators have criticised the current system.

In Summary

For first time buyers still weighing up a Help to Buy ISA against a Lifetime ISA in 2026, the Lifetime ISA usually wins on bonus size and price cap alone.

Existing Help to Buy ISA holders can keep saving until November 2029, but new savers only have the Lifetime ISA available. In practice, choosing between a Help to Buy ISA and a Lifetime ISA now just means picking the stronger bonus.

FAQ

What are the disadvantages of a Lifetime ISA?

The main disadvantage is the 25% withdrawal penalty for non qualifying withdrawals, which claws back some of a saver’s own money, not only the bonus. Savers are also barred from opening one from age 40, and the property price cap excludes higher value homes.

What does Martin Lewis say about the Help to Buy ISA and Lifetime ISA?

Martin Lewis has consistently recommended the Lifetime ISA over the Help to Buy ISA for anyone still able to choose, citing its larger bonus potential. He has also welcomed the First Time Buyer ISA reform, describing the removal of the withdrawal penalty as overdue.

What is the First Time Buyer ISA?

The First Time Buyer ISA is a new savings account proposed by HM Treasury to replace the Lifetime ISA from April 2028. It is designed exclusively for first home purchases, with the government bonus paid on completion rather than during saving, removing the current withdrawal penalty.

Can someone use a Help to Buy ISA and a Lifetime ISA together to buy the same home?

Yes, both can be used toward the same purchase, but only one bonus can be claimed. So the real choice isn’t which account to close, but which bonus to claim when completion day arrives.

What other ISA changes are happening in 2026 and 2027?

Several changes are under review beyond the Lifetime ISA reform, including adjustments to the overall ISA allowance structure. The full set of proposed new ISA rules covers cash ISA transfers, allowance splitting, and reporting changes expected to take effect across the 2026 and 2027 tax years.
