Buying your first home with a Lifetime ISA

A Lifetime ISA (LISA) is a savings account built around two purposes: buying a first home and saving for later life. For first-time buyers, its main attraction is the government bonus. The government adds 25% to whatever you pay in, up to a maximum of £1,000 a year, and the money can be put towards a deposit for a home worth up to £450,000 anywhere in the UK¹.

You can pay in up to £4,000 each tax year, and the government adds a 25% bonus on those contributions, up to a maximum of £1,000 a year¹. The account has been available since April 2017, and it is designed to encourage saving for two significant life events: buying a first home and retirement³.

The rules matter more here than with an ordinary savings account. The property must cost £450,000 or less, you must buy at least 12 months after your first payment into the account, and the money is paid by your provider directly to the solicitor or conveyancer handling your purchase, never to you¹. If you take money out for anything other than a first home, retirement after 60, terminal illness or death, a 25% withdrawal charge applies, which takes back more than the bonus put in¹. The Lifetime ISA is also due to be replaced by a new First Time Buyer ISA, expected in April 2028, though existing accounts continue under the current rules⁵.

How a Lifetime ISA helps first-time buyers: a 25% bonus of up to £1,000 a year

The core deal is simple: for every £4 you save, the government adds £1. The bonus is 25% of whatever you contribute, up to £1,000 per year, which is reached when you pay in the full £4,000¹. Half of all bonuses paid so far have been the maximum £1,000, which tells you most people who use the account save the full amount each year¹¹.

The bonus is paid annually on your contributions, not as a lump sum at the end. That means the money is added to your account each tax year, and any growth on it sits inside the ISA tax free. When the funds are used for a qualifying first-home purchase, the withdrawal is free of the withdrawal charge, and the whole pot, savings plus bonus, goes towards the purchase¹.

For a first-time buyer the practical effect is a larger deposit than saving the same amount outside the account. Someone saving the full £4,000 a year for three years pays in £12,000 and receives £3,000 in bonuses, since the bonus is worth up to £1,000 a year on a full contribution¹. A bigger deposit can also matter for mortgage availability, since lenders assess the loan against the deposit size, though the Lifetime ISA rules themselves say nothing about which mortgage you take, only that the purchase must qualify.

The bonus is not unlimited in time. You can receive it from age 18 up to the age of 50, but you must have opened the account before turning 40¹¹. After 50, no further contributions or bonuses are possible, though the money can stay invested and can be withdrawn without charge from age 60⁹.

Who can open one: ages 18 to 39 and UK residents

To open a Lifetime ISA you must be 18 or over but under 40⁸. In practice this is described as ages 18 to 39: once you reach 40, the chance to open one has passed, though anyone who opened one earlier can keep paying in until they turn 50⁹.

You must also be resident in the UK to open and continue paying into the account⁸. There is an exception for people who live abroad: you can still qualify if you are a member of the armed forces or a crown servant, for example a diplomat or overseas civil servant, or the spouse or civil partner of one⁸.

Only your own money can go in. The technical rules state that only individuals' own money may be contributed, usually in cash, with shares transferable from certain employee share schemes or from another ISA¹³. A parent cannot fund your Lifetime ISA for you, though they can gift you money that you then pay in yourself.

You can only pay into one Lifetime ISA per tax year⁹. The legislation puts it as a rule that a qualifying individual may only make a qualifying addition to a single Lifetime ISA in a particular year¹⁴. You can, however, hold Lifetime ISA accounts with more than one provider over the years, and transfer between them, which is covered later in this page.

The £4,000 Lifetime ISA allowance forms part of the overall £20,000 annual ISA allowance, not an addition to it⁷. So a full £4,000 Lifetime ISA contribution leaves £16,000 of ISA allowance for cash or stocks and shares ISAs in the same tax year. The £4,000 Lifetime ISA limit is set to remain unchanged until April 2031¹⁵. The general rules on who can open an ISA and the ISA allowance are covered elsewhere on the site.

The home must cost £450,000 or less

The single most important condition on the purchase is the price cap. Lifetime ISA funds can be put towards a home costing £450,000 or less, and this limit applies in all areas of the UK, with no higher cap for London or any other region¹. A Treasury committee report noted that the £450,000 cap supports most first-time buyers across the UK, but it is a hard limit: a purchase at £450,001 does not qualify³.

This is a sharp contrast with the older Help to Buy ISA, which capped the property at £250,000 outside London and £450,000 in London¹⁶. The Lifetime ISA's single national cap is more generous outside London and the same within it. It also differs from the First Homes scheme, where the first sale must be at no more than £250,000 after the discount is applied, or £420,000 in London¹⁸.

The cap applies to the purchase price of the home you are buying, and it is the price you pay that matters, not the value of any home you may previously have owned. If the price is above the cap, the withdrawal will not qualify, and the 25% withdrawal charge applies instead². Someone whose target area sits near the limit needs to be confident the purchase will complete at or below £450,000, because a price agreed during the purchase that is renegotiated upwards past the cap would break the condition.

The cap has been criticised in Parliament for the position it creates in high-priced areas, but no regional variation has been introduced, and the government's response of 4 September 2025 kept the limit as it stands³. The narrow guide to the Lifetime ISA property price limit goes into the details.

The 12-month wait and other conditions on your first payment

You must buy the property at least 12 months after you make your first payment into the Lifetime ISA¹. The account must be open for at least a year before you can withdraw to buy your first home, so anyone hoping to use the money for a purchase already underway will be disappointed⁹. A Financial Ombudsman Service case study makes the point concretely: a saver named Sean wanted to use his Lifetime ISA for a house purchase, but because the account was opened less than 12 months before, he had to pay the withdrawal charge²⁰.

The 12-month clock runs from your first payment, not from when you opened the account. If you open the account and leave it empty for six months, the wait starts only when money first goes in. This is worth knowing for anyone planning a purchase a year or more ahead: paying in something small early starts the clock, though the bonus is only earned on what you actually contribute.

Alongside the wait, the purchase must meet all of these conditions¹:

• You are a first-time buyer, buying the home as your main home
• The property costs £450,000 or less
• You buy the property at least 12 months after your first payment into the Lifetime ISA
• You buy with a mortgage, and the purchase is funded by a mortgage from a commercial lender, not a private loan from a connected person
• The withdrawal is paid to your conveyancer

The mortgage condition matters. The purchase must be funded by a mortgage, and legislation from April 2024 confirms that a first-home purchase will not qualify if it is funded by a loan from a person connected to you, such as a relative²². The exclusions are listed in the section on family mortgages below.

Buying with a partner or with more than one Lifetime ISA

Joint purchases are well provided for. The government's model conveyancer declaration sets out that Lifetime ISA funds can be used with other purchasers who may or may not be first-time buyers, with no limit on the number of individuals who can buy a single residential property²³. You can also buy as a joint owner with another person who may already own the property, or as a joint owner with one or more individuals who will use funds held in their own Lifetime ISAs²³.

If the person you are buying with also has a Lifetime ISA, you can both use your savings and your government bonuses, provided you both meet the first-home conditions¹. Two savers each paying in £4,000 a year for three years, with the 25% bonus, would build £30,000 between them before any growth. The technical note confirms that where two people are buying their first home together, they can each use a Lifetime ISA and each benefit from their government bonus¹³.

The rules are more relaxed than the Help to Buy ISA's in one respect: with a Help to Buy ISA, only one half of a couple had to be a first-time buyer for eligibility²⁴. With a Lifetime ISA, the account holder must be a first-time buyer, but the other purchasers on the deed do not have to be, which is what the model conveyancer declaration allows¹. Each first-time buyer could only open one Help to Buy ISA during that scheme's lifetime, whereas a Lifetime ISA holder can hold accounts with different providers over time²⁵.

If you hold both a Help to Buy ISA and a Lifetime ISA, you can only use the government bonus from one of them to buy your first home¹. Money can be transferred from a Help to Buy ISA into a Lifetime ISA, which consolidates the bonus in one place; transferring the other way, from a Lifetime ISA to a Help to Buy ISA, triggers the 25% withdrawal charge¹. The guide to moving a Help to Buy ISA into a Lifetime ISA covers the mechanics.

How to use the money: your solicitor or conveyancer claims it

Lifetime ISA money for a house purchase never passes through your hands. The technical note states that withdrawals must be paid from the ISA manager direct to a conveyancer¹³. Your solicitor or conveyancer applies to your provider on your behalf, the provider pays them, and the money goes towards the purchase at completion¹.

The process in order:

1. Your offer on a qualifying home is accepted and you instruct a solicitor or conveyancer
2. You tell your Lifetime ISA provider you intend to use the funds for a first-home purchase
3. Your conveyancer completes the provider's declaration, confirming the purchase meets the conditions, including the price cap and your first-time buyer status
4. The provider pays the funds to the conveyancer, within the window the rules allow
5. At completion, the money goes towards buying the home, alongside your mortgage and any other deposit funds

The legislation sets a 30-day period that runs from the date the account manager receives the information from your conveyancer²⁶. In practice this means the timing of the payment is tied to the conveyancer's paperwork, not to the completion date itself, so your conveyancer needs to submit the declaration in good time before the money is needed.

On the day of settlement, your solicitor confirms to your lender that the home is now officially in your name, obtains the loan funds, and gathers your contribution towards the cost of the home, which is where the Lifetime ISA money sits²⁷. In Scotland this stage is known as settlement, and the same arrangement applies: the conveyancer receives and distributes the funds²⁷.

The 25% withdrawal charge takes more than the bonus

Money taken out of a Lifetime ISA for anything other than a first home, retirement at 60 or over, terminal illness or death is an unauthorised withdrawal, and it carries a 25% charge¹. The charge is 25% of the amount withdrawn, not 25% of the bonus, which is why it claws back more than the government put in⁹. The Treasury committee's analysis is blunt: the charge causes holders to lose the government bonuses they have received, plus 6.25% of their own contributions¹¹.

The government's own worked example shows the arithmetic. Assuming no growth, savings of £800 earn a £200 bonus, giving a pot of £1,000. Withdrawing the entire pot triggers a charge of £250, leaving £750: the saver is £50 worse off than the £800 they paid in¹. For a partial withdrawal, the charge bites in the same way: to receive £120 in cash for a bill, you must withdraw £160, of which £40 goes in charge¹.

The charge exists by design. The government's position is that the withdrawal charge ensures the Lifetime ISA has been used for its intended purposes, homeownership for first-time buyers or later-life saving³. But the number of people caught by it has grown: unauthorised withdrawals reached 8% of all accounts opened in 2024/25, a figure that has increased year on year⁴.

There is one partial protection. If you have been charged the higher rate of 25%, the difference is paid back into your Lifetime ISA in certain circumstances, which recognises that the charge can take more than the bonus received². The dedicated page on the Lifetime ISA withdrawal charge explains when that refund applies and how to claim it.

Cash or stocks and shares, and how the account affects benefits and pensions

A Lifetime ISA comes in two forms: cash, or stocks and shares²⁸. A cash Lifetime ISA behaves like a savings account, with the bonus added each year; a stocks and shares version invests the money, so the value can fall as well as rise. The Treasury committee concluded that cash Lifetime ISAs may not be the best way to save for retirement, but that stocks and shares Lifetime ISAs can be a useful complementary retirement saving vehicle for some people, including the self-employed¹¹.

If you are saving for a house purchase, the choice has a different flavour. A purchase planned within a few years leaves little time to recover from a fall in investment values, which is why many first-time buyers hold the money in cash. The comparison between a Lifetime ISA and a stocks and shares ISA is covered separately.

The account interacts with means-tested benefits in a way that surprises people. A Lifetime ISA counts towards the calculation of Universal Credit, as other savings and investments do, and it is the realisable value that is used, meaning the amount after deduction of the withdrawal charge, not the full balance in the account³. The page on ISAs and means-tested benefits and the narrow guide to the Lifetime ISA and Universal Credit set out the thresholds.

On pensions, the FCA requires firms to give warnings before you open one. The rules require disclosure of the different savings objectives, house purchase and retirement, and a warning that if you save in a Lifetime ISA instead of enrolling in or contributing to a pension scheme, you may lose the benefit of employer contributions, and your entitlement to means-tested benefits may be affected²⁹. The comparison page on a Lifetime ISA or workplace pension weighs the two, including the fact that Lifetime ISA withdrawals in retirement are entirely free of tax¹¹.

The Lifetime ISA is being replaced by a First Time Buyer ISA

The government has confirmed that a new, simpler ISA product to support first-time buyers, the First Time Buyer ISA, will be offered in place of the Lifetime ISA once it is available⁵. The consultation on the new product was published on 23 June 2026, and independent reporting puts the replacement at April 2028³¹.

For existing holders, nothing is being switched off. The government has stated that it will remain possible to open a Lifetime ISA until the new product becomes available, and account holders can continue to save into their Lifetime ISAs in line with the existing rules indefinitely⁵. There is no requirement to close an account after a house purchase³. If you already have one, you will be able to continue saving into it under the current rules⁶.

The new product is aimed at over-18s buying their first home, and the detail of its terms is still subject to the consultation³⁰. What is clear is the direction of travel: the Lifetime ISA's dual purpose, house purchase and retirement, is being narrowed to a first-time buyer product, and the retirement side of the account is what the replacement gives up. Anyone choosing between opening a Lifetime ISA now or waiting should weigh the certainty of today's rules, including the 25% bonus and the £4,000 limit, against whatever terms the new product arrives with.

Opening, cancelling and moving an account

Opening is done through a provider: banks, building societies and investment platforms offer Lifetime ISAs, and the account is opened with proof of age and residency as for any ISA. The rules on how ISAs work and the ISA deadline at the end of the tax year apply, since the bonus is calculated per tax year.

If you change your mind immediately, there is a cancellation window. A Lifetime ISA for which the account manager receives notification of closure within 30 days after the applicable cancellation period start date is treated as never having been such an account³². From 6 April 2026, the FCA rules replaced the right to cancel with a fourteen calendar day pre-contract right to withdraw your offer³³.

Moving between providers is done by transfer, arranged through the new provider, and a transfer between Lifetime ISAs does not trigger the withdrawal charge¹. NS&I, for example, confirms that you can transfer an ISA balance to another provider by contacting the new provider, who arranges it³⁴. You can hold multiple Lifetime ISA accounts with different providers over the years, though only one can receive payments in any tax year³. The guides on how to transfer an ISA and transferring a Lifetime ISA cover the process, and the warning is always the same: never withdraw the cash and pay it back in yourself, as that is an unauthorised withdrawal.

On death, the Lifetime ISA ends on the date of death, and there is no charge to withdraw the funds¹. Since 6 April 2018, the account can remain open as a continuing account of a deceased investor while the estate is dealt with³⁵. The page on what happens to a Lifetime ISA when you die explains the position for the people handling the estate.

Protection and where to get help

Lifetime ISA providers are regulated by the Financial Conduct Authority, and the FCA's rules require firms to disclose the key terms before you open an account: the annual subscription limits, the tax treatment, the transfer process, eligibility for the government bonus, and the government withdrawal charge and the circumstances in which it might be incurred²⁹. If a firm failed to explain the charge properly, that can be the basis of a complaint.

Complaints go first to the provider, and then, if unresolved, to the Financial Ombudsman Service. The ombudsman has published a case study on exactly this situation: a consumer who faced an unexpected withdrawal charge when moving money between different types of ISA, and the ombudsman's consideration of whether the charge had been properly explained²⁰. The page on complaining about an ISA provider sets out the process and the time limits.

Cash held in a Lifetime ISA is protected by the same deposit protection that covers other savings accounts, up to the FSCS limit, while a stocks and shares Lifetime ISA is covered by the protections that apply to investments instead. The page on how your ISA is protected explains the difference and which applies to which type of account.

For Northern Ireland specifically, the Consumer Council notes that the Lifetime ISA is designed to encourage individuals to save for two significant life events, purchasing their first home and retirement, and publishes guidance for savers there³⁶. Free, impartial help is available from MoneyHelper for general savings questions, and for anything about a specific purchase, your solicitor or conveyancer is the person who handles the Lifetime ISA paperwork, so raising the account with them early avoids delays at completion.
