What Is a Lifetime ISA and How Does It Work?
The Lifetime ISA (commonly known as a LISA) is a government-backed savings account specifically designed to help people save for their first home or for retirement. Launched in April 2017, it has become one of the most valuable tools available to first-time buyers in the UK, offering a generous 25% government bonus on everything you save.
Here’s how it works in simple terms: you can save up to £4,000 per tax year into your LISA, and the government will add a 25% bonus on top. That means if you save the full £4,000, you’ll receive an extra £1,000 for free. The bonus is paid monthly, so you don’t have to wait until the end of the tax year to see it added to your account.
To be eligible to open a LISA, you must be aged 18 to 39. Once opened, you can continue contributing until you turn 50, even though you can no longer open a new one after 39. The account must have been open for at least 12 months before you can use the funds (including the bonus) to purchase a property.
The property you buy must cost £450,000 or less, which comfortably covers the vast majority of new build homes across England, Wales, Scotland, and Northern Ireland. You must be a genuine first-time buyer – meaning you’ve never owned a property or land before – and the property must be purchased with a mortgage. You’ll want to ensure you understand the full new build buying process so you know exactly when and how the LISA funds are released.

LISA vs Regular Savings: A Detailed Comparison
To truly appreciate the power of the Lifetime ISA, it helps to compare it directly against alternative savings options. The 25% government bonus makes an enormous difference to your total savings over time, but there are also some limitations you should be aware of.
| Feature | Lifetime ISA (Cash) | Regular Cash ISA | Standard Savings Account | Stocks & Shares ISA |
|---|---|---|---|---|
| Annual contribution limit | £4,000 | £20,000 | No limit | £20,000 |
| Government bonus | 25% (up to £1,000 per year) | None | None | None |
| Tax on interest | Tax-free | Tax-free | Taxable (above PSA) | Tax-free |
| Early withdrawal penalty | 25% penalty on amount withdrawn | None | None | None |
| Property price cap | £450,000 | N/A | N/A | N/A |
| Age requirement | 18–39 to open | 16+ (some 18+) | Any age | 18+ |
| Minimum holding period | 12 months | None | None (may have notice) | None |
| Access to funds | Property purchase or age 60+ | Anytime | Anytime (or with notice) | Anytime |
| Risk level | Low (cash LISA) | Low | Low | Medium to High |
| Best for | First-time buyers with 1+ year timeline | Flexible short-term savings | Emergency funds | Long-term growth (5+ years) |
The comparison makes the LISA’s advantage crystal clear: the 25% bonus is unmatched by any other savings product. A saver putting £333 per month into a LISA effectively earns a 25% guaranteed return, which no savings account or investment can reliably match. However, the £4,000 annual cap means you’ll need to use other accounts alongside your LISA if you’re saving more than that.
The Optimal Savings Strategy
The smartest approach for most first-time buyers is to maximise the LISA first, then save any additional money into a high-interest Cash ISA or regular savings account. This way, you get the full £1,000 government bonus each year while keeping the rest of your savings in a flexible, accessible account.

Year-by-Year Savings Projection with LISA Bonus
One of the most motivating things about the LISA is seeing how quickly your savings grow when the government bonus is factored in. The table below shows what happens if you save the maximum £4,000 per year, along with projections for lower contribution levels. These figures assume a cash LISA with a modest interest rate of 4% per annum.
| Year | Saving £4,000 per year (Your Total) | Total with 25% Bonus | Total with Bonus + Interest |
|---|---|---|---|
| Year 1 | £4,000 | £5,000 | £5,200 |
| Year 2 | £8,000 | £10,000 | £10,608 |
| Year 3 | £12,000 | £15,000 | £16,232 |
| Year 4 | £16,000 | £20,000 | £22,081 |
| Year 5 | £20,000 | £25,000 | £28,164 |
| Year 6 | £24,000 | £30,000 | £34,491 |
| Year 7 | £28,000 | £35,000 | £41,071 |
| Year 8 | £32,000 | £40,000 | £47,914 |
The numbers tell a compelling story. After just five years of maxing out your LISA contributions, you’d have over £28,000 – enough for a 10% deposit on a £280,000 new build home. That’s £8,164 more than you actually saved yourself, thanks to the government bonus and compound interest.
What If You Can’t Afford £4,000 Per Year?
Don’t be discouraged if you can’t max out the full allowance. Even smaller contributions receive the same 25% bonus rate:
- £100 per month (£1,200 per year): Grows to approximately £7,830 after 5 years (including bonus and interest)
- £200 per month (£2,400 per year): Grows to approximately £15,660 after 5 years
- £250 per month (£3,000 per year): Grows to approximately £19,575 after 5 years
- £333 per month (£4,000 per year): Grows to approximately £28,164 after 5 years (maximum)
The key takeaway: any amount you put in receives the 25% bonus. Even £50 per month adds up to £750 per year with the bonus included – that’s £150 of free money from the government every year.
Choosing the Best LISA Provider
There are two types of Lifetime ISA: Cash LISAs and Stocks and Shares LISAs. For most first-time buyers saving for a property purchase within 5 years, a Cash LISA is the safer and more appropriate choice. Here’s what to look for when choosing a provider.
Cash LISA Providers
When selecting a Cash LISA, the most important factor is the interest rate. Rates can vary significantly between providers, and over several years the difference can amount to hundreds of pounds. Top Cash LISA providers typically include:
- Moneybox: Popular app-based provider with competitive rates and a user-friendly interface. Allows contributions from as little as £1
- Skipton Building Society: One of the original LISA providers, offering a straightforward online account with historically competitive rates
- Nottingham Building Society: Offers a competitive Cash LISA with the option to manage your account online or in-branch
- Beehive Money (part of the Furness Building Society): App-based Cash LISA with competitive rates and easy management
Stocks and Shares LISA Providers
If you have a longer savings timeline (five years or more), a Stocks and Shares LISA could potentially deliver higher returns through investment growth. However, your capital is at risk – your investments could fall in value. Popular providers include AJ Bell, Hargreaves Lansdown, and Moneybox (which offers both cash and investment LISAs).
What to Compare When Choosing
- Interest rate (for Cash LISAs): The higher the better – check if it’s fixed or variable
- Fees: Most Cash LISAs are fee-free, but some Stocks and Shares LISAs charge platform or fund management fees
- Ease of use: Can you manage the account via an app or online? Is it easy to set up regular contributions?
- Withdrawal process: When it comes time to buy, how smoothly does the provider process the property purchase withdrawal? Some are faster than others
- Customer service: Read reviews and check satisfaction ratings – you may need support during the property purchase process
Regardless of which provider you choose, the 25% government bonus is the same across all of them. The provider only affects the interest rate, fees, and user experience. When you’re ready to buy, you’ll also want to understand how conveyancing for a new build works, as your solicitor plays a key role in releasing LISA funds.
Withdrawal Rules, Penalties, and Important Caveats
While the LISA is an excellent savings tool, it comes with strict rules about when and how you can access your money. Understanding these rules upfront will help you avoid costly penalties and plan your purchase timeline effectively.
Withdrawals for Property Purchase
To use your LISA funds for buying a home, all of the following conditions must be met:
- You must be a first-time buyer (never previously owned property or land in the UK or abroad)
- The property must cost £450,000 or less
- You must buy with a mortgage (not cash)
- The LISA must have been open for at least 12 months
- The property must be your main residence (not a buy-to-let)
When you’re ready to purchase, your solicitor or conveyancer will request the funds directly from your LISA provider. The money – including the government bonus – is sent to your solicitor to be used towards your deposit and completion costs. This process typically takes around 30 days, so factor this into your purchase timeline.
The Withdrawal Penalty
If you withdraw money from your LISA for any reason other than buying your first home (before age 60) or a terminal illness, you’ll face a 25% withdrawal penalty. This might sound like it just removes the bonus, but it actually takes more than that.
Here’s why: the 25% penalty is applied to the total amount withdrawn (your savings plus the bonus), not just the bonus portion. For example:
- You save £1,000, government adds £250 bonus = £1,250 total
- You withdraw the full £1,250
- 25% penalty on £1,250 = £312.50 penalty
- You receive £937.50 – that’s £62.50 less than you originally put in
This means an unauthorised withdrawal doesn’t just cost you the bonus – you actually lose some of your own money. This is a crucial point that catches many people off guard. The LISA should only be used if you’re confident you’ll use it for a qualifying property purchase.
What Happens If the Property Costs More Than £450,000?
If you find your dream new build home but it’s priced above the £450,000 cap, you cannot use the LISA bonus for that purchase. You would face the 25% withdrawal penalty if you take the money out. This is an important consideration when looking at properties, particularly in London and the South East where new build prices can easily exceed this threshold.
However, £450,000 comfortably covers the majority of new build homes across the UK, including many developments in and around major cities. To explore options within this range, start by searching for new build homes in your target area.
Buying with a Partner
If you’re buying as a couple and you’re both first-time buyers, you can each have your own LISA and both use the bonus towards the same property. That means up to £8,000 in annual contributions between you, with up to £2,000 in government bonuses each year. The £450,000 property price cap applies to the property itself, not per person, so both bonuses can be used regardless of the property price (as long as it’s under the cap).
Using Your LISA Specifically for a New Build Purchase
There are some important practical considerations when using a LISA to buy a new build property that differ from buying an older home.
Off-Plan Purchases and Timing
If you’re buying a new build off-plan, there can be a gap of 6–24 months between reserving and completing. This actually works in your favour with a LISA, as it gives you more time to save and accumulate bonus payments. However, you need to ensure your LISA has been open for at least 12 months before completion – plan ahead and open your LISA early. For guidance on the reservation stage, see our reservation guide for first-time buyers.
The Reservation Fee vs LISA Funds
When you reserve a new build, you’ll typically pay a reservation fee of £500–£2,000. This comes from your own funds – you cannot use LISA money for the reservation fee. The LISA funds are only released at exchange or completion (depending on the solicitor’s process) and go towards the deposit and purchase costs. Make sure you have separate funds available for the reservation fee.
LISA Withdrawal Timing
The process of withdrawing LISA funds for a property purchase takes approximately 30 days from when your solicitor submits the request. For new build purchases, your solicitor will typically coordinate this so the funds arrive in time for completion. However, new build completion dates can sometimes shift, so communicate closely with your solicitor and LISA provider to ensure everything aligns. Understanding the conveyancing process will help you manage these timings.
Developer Incentives and the LISA
Many new build developers offer incentives for first-time buyers, such as contributions towards legal fees, help with stamp duty, or even deposit contributions. These incentives can work alongside your LISA – there’s no conflict between using your LISA bonus and benefiting from developer schemes. This combination can significantly reduce your out-of-pocket costs.
| Scenario | Your Savings | LISA Bonus | Developer Incentive | Total Towards Purchase |
|---|---|---|---|---|
| 5 years saving, no incentives | £20,000 | £5,000 | £0 | £25,000 |
| 5 years saving + legal fees paid | £20,000 | £5,000 | £1,500 (legal fees) | £26,500 |
| 5 years saving + deposit contribution | £20,000 | £5,000 | £5,000 (deposit top-up) | £30,000 |
| Couple saving 5 years + incentives | £40,000 | £10,000 | £3,000 (mixed incentives) | £53,000 |
Frequently Asked Questions
Can I transfer an existing Help to Buy ISA to a Lifetime ISA?
You cannot directly transfer a Help to Buy ISA into a LISA. However, you can close your Help to Buy ISA, withdraw the funds, and then deposit them into your LISA (subject to the £4,000 annual contribution limit). Remember that once you close the Help to Buy ISA, you cannot reopen one as they are no longer available to new applicants. Also, the funds you transfer count towards your LISA annual limit, so plan your contributions carefully across the tax year.
What happens to my LISA if I don’t end up buying a home?
If you decide not to buy a property, your LISA remains open and your money continues to earn interest or investment growth. You can leave it until you turn 60, at which point you can withdraw everything (savings, bonus, and growth) completely tax-free for retirement. If you need the money before 60 and not for a first home, the 25% withdrawal penalty applies. This makes the LISA still useful as a retirement savings vehicle even if your property plans change.
Can I have a LISA and contribute to a pension at the same time?
Yes, absolutely. Your LISA contributions are completely separate from your pension contributions. Both have their own tax advantages, and there’s no conflict between the two. In fact, financial advisers often recommend maximising both – your LISA for your first home deposit, and your pension for long-term retirement savings. Your LISA contribution also counts towards your overall £20,000 ISA allowance for the tax year.
I turned 40 – can I still contribute to my LISA?
If you opened your LISA before turning 40, you can continue contributing until the day before your 50th birthday. The age 18–39 restriction only applies to opening a new account. If you’re approaching 39 and thinking about buying in the future, open a LISA now – even with just £1 – to keep the option available. The 12-month clock starts from when you open it, so acting early is always better.
Is the LISA bonus counted as part of my deposit by mortgage lenders?
Yes, most mortgage lenders will count the LISA bonus as part of your deposit. This means your LISA savings plus the 25% bonus contribute to your overall deposit amount, which affects your loan-to-value ratio and the mortgage rates available to you. For example, if you need a £25,000 deposit and have £20,000 of your own savings in a LISA, the £5,000 bonus brings you to your target without needing to find additional funds.
