Autumn Budget 2026: Lifetime ISA penalty cut and new help for first-time buyers

First-time buyers have been handed a change to the Lifetime ISA rules in the Autumn Budget, with the Government cutting the withdrawal penalty from 25% to 20% for people buying a home above the current £450,000 property-price limit.

And there's more news for aspiring homeowners. Chancellor John Healey has confirmed that the annual cash ISA allowance will remain at £20,000, reversing plans to reduce it, while also outlining a new First-Time Buyer ISA to replace the existing Lifetime ISA for new savers.

There's also a new route onto the property ladder on the horizon, with the proposed Your First Home scheme potentially allowing eligible buyers to purchase a property with a deposit of just 2.5%.

But before you start reworking your savings goals, there are a few catches worth understanding. The LISA penalty reduction doesn't apply to every withdrawal, and the new savings and deposit schemes still have important details to be finalised.

Here's what's changing, who could benefit and what it means for the money you're putting aside for your first home.

What's changed for first-time buyers in Budget 2026?

The Autumn Budget has brought several changes for people saving towards their first home, from new ISA rules to plans that could make getting a deposit together a little easier.

Here's what you need to know:

• Lifetime ISA withdrawal penalty cut: The charge has been reduced from 25% to 20% for existing LISA holders buying their first home above the £450,000 property-price limit. The change takes effect from 28 October 2026, but the standard 25% charge still applies to other non-qualifying withdrawals.

• Cash ISA allowance stays at £20,000: The Chancellor has reversed plans to reduce the annual cash ISA limit to £12,000 for under-65s. Savers of all ages will retain the £20,000 allowance, giving people saving for a deposit more flexibility.

• New First-Time Buyer ISA planned: The Government intends to replace the Lifetime ISA for new savers with an account that pays the government bonus when you buy your first home, rather than while you're saving. The final bonus, contribution limits and launch arrangements are still to be confirmed.

• New 2.5% deposit scheme: The proposed Your First Home scheme could allow eligible buyers to purchase qualifying new-build properties in England with a deposit of just 2.5%, supported by a government-backed equity loan. Full eligibility details and the launch date are still being finalised.

While the announcements could make a difference to how people save and buy their first home, it's worth remembering that not all the changes are happening immediately. The LISA penalty reduction has taken effect, while the new First-Time Buyer ISA and deposit scheme remain in development.

And whether you're saving £50 a month or getting close to your deposit target, understanding which rules apply to you could make a real difference to how much of your money you get to keep.

Your First Home: Could you buy a house with a 2.5% deposit?

Getting a deposit together is one of the biggest hurdles facing first-time buyers, and the Government's proposed Your First Home scheme could help eligible buyers in England get onto the property ladder with just 2.5% saved.

The scheme would apply to qualifying new-build homes purchased through participating developers. Buyers would contribute a 2.5% deposit, with a government-backed equity loan covering a further 20% of the property's value and a mortgage making up the remainder.

The proposed equity loan would be interest-free for the first five years, although buyers would still need to repay the loan under the scheme's terms. Importantly, an equity loan isn't a grant, so the long-term cost matters just as much as the smaller deposit.

While the Government has announced the scheme's proposed structure, applications aren't open yet. Full eligibility requirements, including household income limits, local property-price caps, the terms of the equity loan after the interest-free period and the launch date, still need to be confirmed.

How much deposit would you need?

Let's take a £200,000 property as an example.

With a conventional 5% deposit, you would need to save £10,000.

With a 2.5% deposit, you would need £5,000.

Under the proposed Your First Home structure, the purchase could be funded through:

• A £5,000 deposit from the buyer.

• A £40,000 government-backed equity loan.

• A £155,000 mortgage.

That could make the initial deposit much more manageable, particularly for someone who can afford mortgage payments but has struggled to build savings while renting.

However, the equity loan isn't free money. It's a financial obligation that must eventually be repaid.

The final repayment terms will matter enormously when comparing the scheme against an ordinary mortgage.

Does a smaller deposit mean a cheaper home?

Not necessarily, and this is one of the most important things for first-time buyers to understand.

The proposed scheme could reduce the amount you need to save upfront, but it doesn't reduce the price of the property.

You'll still need to satisfy mortgage affordability checks, understand the terms of the equity loan and have enough money left for the costs of moving and maintaining your home.

If you're buying a new-build property, it's also worth comparing its price and long-term value with existing properties nearby.

Getting together a smaller deposit might help you buy sooner, but the mortgage, bills and maintenance will still need to fit comfortably into your budget afterwards.

Is the Lifetime ISA being replaced?

The Government has confirmed plans to replace the Lifetime ISA with a new First-Time Buyer ISA for people opening accounts in the future.

However, existing Lifetime ISA accounts are not being closed.

People who already have a LISA will be able to continue saving into their accounts and using them under the existing rules, including for retirement.

Eligible savers can also continue opening Lifetime ISAs until the replacement product becomes available.

That's particularly important for people who have already spent years building a deposit and are worried about what happens to the government bonuses they've earned.

You don't need to rush into withdrawing your savings simply because a new scheme has been announced, especially when doing so could trigger a withdrawal charge.

What are the current Lifetime ISA rules?

A Lifetime ISA, often called a LISA, allows eligible people aged 18 to 39 to open an account and save towards their first home or retirement.

You can currently contribute up to £4,000 each tax year, with the Government adding a 25% bonus worth up to £1,000 annually.

To use your savings towards a first home without a withdrawal charge, the property must currently cost no more than £450,000, your LISA must have been open for at least 12 months, and you must meet the other qualifying conditions.

The existing rules also allow penalty-free withdrawals from age 60 or in certain circumstances involving terminal illness.

The Government has been reviewing the property-price limit as part of its ISA reforms, but a new cap hasn't been independently confirmed in the published guidance.

For now, £450,000 remains the existing Lifetime ISA property-price limit.

Who benefits from the Lifetime ISA withdrawal penalty cut?

The Autumn Budget has announced a reduction in the Lifetime ISA withdrawal charge from 25% to 20% for existing savers purchasing their first home above the £450,000 property-price limit.

The change applies from 28 October 2026 and means affected buyers will no longer lose part of their original contributions through the withdrawal charge, assuming no investment losses.

Previously, someone who saved £4,000 into a Lifetime ISA would receive a £1,000 government bonus, bringing the balance to £5,000. Withdrawing that money to buy a property above £450,000 would have triggered a £1,250 charge, leaving them with £3,750.

Under the new 20% charge, the same withdrawal would result in a £1,000 deduction, leaving them with their original £4,000.

That means the buyer loses the government bonus, but not an additional portion of their original contributions in this example.

Importantly, the Government hasn't increased the £450,000 property-price cap itself. Instead, it has reduced the charge for people buying above that limit.

The standard 25% withdrawal charge still applies to other non-qualifying withdrawals, including accessing LISA savings for an unexpected household expense. Existing savers should therefore check which rules apply before withdrawing money.

What is the new First-Time Buyer ISA?

The Government plans to introduce a new First-Time Buyer ISA designed specifically for people saving towards their first home.

Unlike the existing Lifetime ISA, which adds the government bonus while you're saving, the proposed new account would award the bonus when you purchase a qualifying property.

This would allow people to withdraw their own contributions without the existing LISA-style penalty if their circumstances change.

For example, somebody saving £50 a month towards a deposit who suddenly needs £500 for an unexpected expense could access their money without losing part of those contributions through the current withdrawal charge.

They wouldn't receive a government first-home bonus on money withdrawn for another purpose, but their original savings wouldn't be reduced by the same penalty.

The proposed scheme would also remove the current upper age limit for opening an account, potentially making government-backed first-home savings available to people who start their homebuying journey later in life.

Will the new First-Time Buyer ISA offer a 25% bonus?

The Government intends the new account to include a bonus for eligible first-time buyers.

However, the exact bonus percentage, annual contribution limit and maximum qualifying property price have not yet been confirmed.

That means it's too early to assume the replacement will offer exactly the same £1,000 maximum annual bonus as the current Lifetime ISA.

These details will make a significant difference when comparing the two products.

When will the First-Time Buyer ISA launch?

The Government has been working towards introducing the replacement account in April 2028, although the final launch arrangements need confirmation.

Until the new product becomes available, eligible savers can continue opening and contributing to Lifetime ISAs under the existing rules.

What happens if you already have a Lifetime ISA?

If you've already opened a Lifetime ISA, you can continue holding and contributing to it under the existing arrangements.

The Government has said existing holders will be able to use their accounts for a qualifying first-home purchase or retirement, even after the replacement ISA launches.

However, the final rules about using or contributing to both products still need to be established.

There's also an important distinction between transferring money and withdrawing it.

A withdrawal from an existing LISA for a non-qualifying reason can still trigger the current charge, so don't assume you can move the money into another account without consequences.

Before making changes, check the terms with your provider and make sure you understand whether the transaction is treated as an eligible transfer or a withdrawal.

Cash ISA allowance to stay at £20,000 after Budget U-turn

Chancellor John Healey has confirmed that the annual cash ISA allowance will remain at £20,000 for savers of all ages, reversing plans to reduce the limit to £12,000 for people under 65 from April 2027.

The reduction had been announced in the previous Budget as part of efforts to encourage more people to invest in stocks and shares rather than keep their savings in cash.

However, the Chancellor has now abandoned that approach, meaning savers will continue to be able to put up to £20,000 a year into cash ISAs, within the overall ISA allowance.

For first-time buyers, this means the option to save larger amounts towards a property deposit in a tax-free cash account will remain available.

Unlike a Lifetime ISA, a standard cash ISA doesn't provide a government bonus towards a first home, but it also doesn't carry the LISA's specific withdrawal penalty. Whether you can access the money immediately will depend on the terms of the individual account.

Of course, not everyone has £20,000 to save each year, and that's worth remembering when looking at the headlines. Someone putting away £50 a month is still building £600 in savings over a year, before interest, and the most useful account will depend on their circumstances rather than how close they can get to the maximum allowance.

What is the new Starter ISA announced in the Budget?

The Chancellor has also announced plans to work with the financial services industry on a new Starter ISA designed to encourage people to begin investing.

This is separate from the proposed First-Time Buyer ISA that is intended to replace the Lifetime ISA.

The Starter ISA is aimed at helping first-time investors, rather than providing a dedicated government bonus for buying a property.

Further details, including eligibility, contribution limits, incentives and a launch date, have yet to be confirmed.

For somebody hoping to buy their first home in the next few years, it's particularly important not to confuse saving with investing. Investments can rise and fall in value, so an account designed for longer-term investing won't necessarily suit money needed for a deposit in the near future.
