UK Lifetime ISA: First Home Purchase Process in 2026
How to use a Lifetime ISA to buy your first home in 2026 -- the 25% government bonus, property price limit, conveyancing process, and what happens if plans change.
The Lifetime ISA (LISA) remains one of the most generous savings products available to UK first-time buyers. A 25% government bonus on top of your own savings is hard to beat -- but the rules are strict, and the penalty for getting it wrong is punishing. This guide explains exactly how the LISA works for a first home purchase in 2026, from opening the account through to completion day.
What Is the Lifetime ISA?
The Lifetime ISA was introduced in 2017 as a replacement for the Help to Buy ISA (which closed to new applicants in 2019). It is a government-backed savings account designed for two purposes:
- Buying your first home
- Saving for retirement (accessible from age 60)
You can open a LISA if you are aged between 18 and 39 (inclusive). Once open, you can contribute until age 50. The government adds a 25% bonus on top of everything you save, up to a maximum contribution of £4,000 per year -- meaning up to £1,000 bonus per year.
The bonus is paid monthly (on contributions made in the previous month), so your savings grow with the bonus adding up throughout the year rather than in one annual payment.
The Numbers: How the Bonus Accumulates
| Year | Your Savings | Government Bonus | Total |
|---|---|---|---|
| 1 | £4,000 | £1,000 | £5,000 |
| 2 | £4,000 | £1,000 | £10,000 |
| 3 | £4,000 | £1,000 | £15,000 |
| 4 | £4,000 | £1,000 | £20,000 |
| 5 | £4,000 | £1,000 | £25,000 |
If you open at age 18 and save the maximum every year until you buy at age 32 (14 years), you could accumulate £70,000 (£56,000 your money + £14,000 bonus) -- all before investment growth on a Stocks and Shares LISA.
The LISA does not count towards your standard annual ISA allowance of £20,000... wait, it does. The £4,000 LISA limit is part of your overall £20,000 ISA allowance, not in addition to it. So in any tax year, the maximum you can save across all ISAs is £20,000, of which up to £4,000 can go into a LISA.
Who Can Use a LISA for a Home Purchase?
To use your LISA to buy a first home:
- You must be a first-time buyer: You must never have owned a home (in the UK or abroad) before. This includes property you may have inherited or received as a gift.
- All co-buyers must be first-time buyers: If you are buying jointly, every buyer on the mortgage must be a first-time buyer with their own LISA (or without any property ownership history). One buyer having previously owned a property disqualifies the use of LISA funds for that purchase (though the other buyer may still use their own LISA if they personally meet the criteria -- check with your LISA provider).
- The property must cost no more than £450,000: This is the current cap, unchanged since 2017. In many areas of the UK the cap is not a major constraint, but in London and the South East, many properties now exceed this limit.
- You must buy with a mortgage: The property must be purchased using a mortgage. You cannot use a LISA for a cash purchase.
- The LISA must have been open for at least 12 months: You cannot open a LISA today and use it next month. There is a 12-month minimum holding period before you can use the funds for a first home purchase.
The 12-Month Rule: Open Early
The 12-month clock starts from the date you made your first payment into the LISA -- not from when you opened it.
This means if you are planning to buy in the next year or two, you should open a LISA and make at least a small contribution now, even if you cannot afford the full £4,000 yet. Opening with £1 starts your clock.
Many providers allow you to open a Cash LISA online in minutes. The minimum investment varies by provider -- some accept as little as £1, others require £50 or £100 to open.
Cash LISA vs Stocks and Shares LISA
There are two types of LISA:
Cash LISA: Works like a savings account. Your money earns interest plus the 25% government bonus. No risk of losing your savings. Suitable for shorter time horizons (buying in 1--3 years) where you cannot afford investment volatility.
Stocks and Shares LISA: Your savings are invested in funds (stocks, bonds, or a mix). Over the long term, investments tend to grow faster than cash savings, and the 25% bonus makes this even more compelling. Suitable for longer time horizons (buying in 4+ years) where you can ride out market fluctuations.
The risk of a Stocks and Shares LISA: If markets fall close to when you need to buy, you could end up with less than you contributed. Some first-time buyers switch from a Stocks and Shares LISA to a Cash LISA as they get closer to purchase.
The 25% Withdrawal Penalty -- Why It Is Worse Than It Sounds
Here is the maths that trips people up:
- You contribute £1,000 to your LISA
- The government adds £250 bonus
- Total in your LISA: £1,250
- You need to withdraw for a non-qualifying reason
- Penalty: 25% of £1,250 = £312.50
- You receive: £937.50
You put in £1,000. You get back £937.50. You have lost £62.50 of your own money.
This happens because the 25% penalty is designed to recover the 25% bonus, but it is applied to the total balance (including the bonus) rather than just the bonus itself. In percentage terms, the government is recovering more than it gave you.
The only situations where a withdrawal is penalty-free are:
- Buying your first home (and meeting all the conditions above)
- Reaching age 60 (for retirement)
- Being diagnosed with a terminal illness
Note: The government temporarily reduced the penalty from 25% to 20% during the Covid period (2020--2021) to allow penalty-free withdrawals. This temporary reduction has ended. The penalty is back to 25%.
The Purchase Process: How the LISA Funds Are Released
The LISA purchase process involves your conveyancer (solicitor or licensed conveyancer) -- the funds are never paid directly to you.
Here is the step-by-step process:
Step 1 -- Instruct your conveyancer: When you find a property and have an offer accepted, instruct a conveyancer to handle the legal work.
Step 2 -- Inform your LISA provider: Tell your LISA provider you intend to use your LISA for a home purchase. They will provide you with forms and guidance.
Step 3 -- Conveyancer submits a request: Your conveyancer contacts your LISA provider using a HMRC-approved process (the "conveyancer's declaration"). They confirm the purchase meets the criteria (first-time buyer, mortgage, price under £450,000, property is residential).
Step 4 -- Funds transferred: The LISA provider transfers the funds directly to your conveyancer's client account. This typically takes 30 days from the request, so your conveyancer needs to request early enough not to delay exchange or completion.
Step 5 -- Completion: Your conveyancer uses the LISA funds (along with your deposit and mortgage funds) to complete the purchase.
Important: You never handle the money yourself. If you withdraw from your LISA and then use cash for the deposit, that is an unauthorised withdrawal and the penalty applies.
If Your Plans Change
If the purchase falls through: If you have requested the LISA funds but the sale does not complete, your conveyancer returns the funds to the LISA provider. Providing the funds were not released to you personally, no penalty applies. The funds go back into your LISA.
If you decide not to buy: If you decide you no longer want to buy a home and want your LISA money, the 25% penalty applies unless you are 60 or terminally ill.
If you want to buy above £450,000: If you find your dream home above the £450,000 price cap, you cannot use the LISA for that purchase. Your options are:
- Withdraw with the 25% penalty (and accept the loss)
- Leave the LISA untouched and use other savings for the deposit, then use the LISA at age 60 for retirement
- Keep saving in the LISA for a different, eligible property in the future
Combining LISA with Other Schemes
Help to Buy Equity Loan: No longer available for new applicants in England (closed March 2023).
Mortgage Guarantee Scheme: You can use a LISA deposit alongside a government-guaranteed mortgage. No conflict.
Shared Ownership: You can use a LISA to buy a shared ownership property, provided the full market value (not just your share) is £450,000 or less.
First Homes Scheme: First Homes properties are discounted by at least 30% from market value. You can use a LISA for a First Homes purchase provided the discounted purchase price is under £450,000.
Joint purchase where one buyer has a LISA and the other does not: Both buyers must be first-time buyers for the LISA to be used, but only the buyer with the LISA needs to have one. The other buyer does not need a LISA. However, both must be first-time buyers.

Can I open a LISA if I already have a Help to Buy ISA? Yes. You can hold both, but you can only use one of them for a home purchase -- not both. If you have a Help to Buy ISA, you can transfer it to a LISA (subject to provider rules), or keep both and choose which to use when buying.
Can I transfer my Cash LISA to a Stocks and Shares LISA? Yes. You can transfer between LISA providers and between Cash and Stocks and Shares versions. The 12-month clock is not reset by a transfer -- it runs from your first contribution.
What if the property I am buying is a new build? New builds are eligible as long as the purchase price is £450,000 or less. The LISA funds process is the same -- your conveyancer requests the funds from your provider.
I am buying with a partner who already owns a property. Can I still use my LISA? If your partner has previously owned a property, they are not a first-time buyer and cannot use their LISA for this purchase. Your status as a first-time buyer means you may still be able to use your own LISA -- but check carefully with your LISA provider and conveyancer, as HMRC rules require all buyers to be first-time buyers for the LISA to be used. This is a complex area and professional advice is recommended.
Can I withdraw from my LISA to fund a self-build? Self-builds are eligible if the land is purchased with a mortgage, the property is for your residential use, and the total costs are within the £450,000 limit. The rules around self-builds and LISAs are complex -- check with your provider.
How long does the LISA withdrawal take during a purchase? The transfer from your LISA provider to your conveyancer typically takes up to 30 days from when your conveyancer submits the request. Plan ahead -- if your conveyancer submits the request too close to completion, delays can cause problems.
Can I put my LISA in trust? No. A LISA is an individual account and cannot be placed in trust. It is personally owned by you.
What happens to my LISA if I die before using it? Your LISA forms part of your estate. The funds (including bonus) can be withdrawn without the 25% penalty on death. They would be subject to Inheritance Tax if your estate exceeds the nil rate band.
Is the LISA bonus taxable? No. The government bonus on a LISA is tax-free. Interest or investment growth within the LISA is also tax-free (like all ISA savings).
Can I use a LISA if I am buying abroad? No. The LISA first home purchase benefit only applies to UK residential property. Using it for a foreign property purchase would be an unauthorised withdrawal with the 25% penalty.
