Lifetime ISA home purchase: does your UK first home qualify?

A Lifetime ISA can help fund a first home in the UK, but only if the buyer, property and withdrawal meet the scheme’s conditions. The purchase price, first payment date and mortgage arrangements matter. The money normally goes to your conveyancer, not your current account, and an ineligible withdrawal can trigger a charge.

• Check the property against the scheme’s price ceiling before relying on the savings.
• The waiting period starts with your first payment, not simply opening the account.
• Each buyer using a Lifetime ISA must qualify individually.
• Arrange the withdrawal through your conveyancer and keep separate money for other buying costs.

When can a Lifetime ISA fund a UK first home?

According to GOV.UK guidance checked on 27 October 2026, a qualifying property must cost £450,000 or less. The purchase must happen at least 12 months after the first payment into the Lifetime ISA, and it must involve a mortgage. A solicitor or conveyancer handles the release of the savings.

The property must be in the UK and intended as your home. HM Revenue & Customs’ conveyancer guidance, updated on 28 March 2018, sets out the residence and purchase requirements. This is not a general deposit subsidy that can be redirected towards any property.

Check your payment record before choosing a completion date

An unused account and a funded account are not interchangeable for the waiting period. Ask the provider to confirm the first payment date before assuming the money will be available. If the planned purchase comes too early, discuss alternative funding and timing with the conveyancer rather than withdrawing it yourself.

The mortgage also needs checking: GOV.UK excludes certain private mortgages involving relatives and connected family relationships. Having a loan agreement is not, by itself, proof that the purchase qualifies. Unusual financing arrangements warrant a specific eligibility check.

Does buying with someone else change eligibility?

You can buy with another person without both having identical savings arrangements. HMRC’s technical guidance allows a qualifying Lifetime ISA holder to buy jointly with someone who is not a first-time buyer. However, that does not make the other person eligible to use their own Lifetime ISA for the purchase.

If both purchasers want to use Lifetime ISA savings, each must meet the relevant conditions. Check both account histories and declarations separately. One buyer’s eligibility cannot substitute for the other’s, and combining deposits does not remove the property price ceiling.

Shared ownership has a separate valuation trap

For shared ownership, HMRC applies the £450,000 ceiling to the full sale value rather than just the initial share being bought. An affordable-looking share is therefore not enough to establish eligibility. Ask the conveyancer which property value applies before including the Lifetime ISA in your funding plan.

Joint ownership also differs from sharing an everyday savings account. Our explanation of withdrawal rights on UK joint savings accounts covers that separate issue. Agreeing how to save together does not resolve the legal conditions attached to each person’s Lifetime ISA.

How do you arrange the withdrawal without a charge?

Start with the provider’s house-purchase process and your conveyancer’s requirements. The conveyancer requests the funds using the required declarations, and the provider pays the conveyancer directly. Moving money into your current account first is not the qualifying house-purchase route.

1. Confirm the property price, first payment date, mortgage and personal eligibility.
2. Give your conveyancer the provider’s details, account number and amount required.
3. Supply the property address and purchase information for the declarations.
4. Agree when the request needs to be submitted and how delays will be handled.
5. Keep correspondence showing the request, release of funds and eventual completion.

HMRC’s conveyancer guidance says the provider should pay within 30 days of receiving the declaration. That is a planning consideration, not a reason to leave the request until the last moment. Ask about provider processing requirements before agreeing a timetable that depends on these funds.

The withdrawal must cover the property purchase price, rather than unrelated expenses. Legal bills, surveys, moving costs and mortgage charges need their own funding plan. Our guide to comparing mortgage product fees for UK first-time buyers explains why the advertised rate is only part of the borrowing cost.

What if the purchase changes or falls through?

A revised price, different property or delayed completion can affect the withdrawal arrangements. Tell the conveyancer and provider rather than assuming the original request still works. HMRC normally requires completion within 90 days of the conveyancer receiving the withdrawn money, with extensions available through the provider when the purchase continues.

If the purchase fails, the conveyancer returns the withdrawn funds directly to the Lifetime ISA provider. A shortfall can be treated as a chargeable withdrawal. Money already released for a purchase is therefore not a flexible pot for another purpose while you decide what to do next.

GOV.UK states that unauthorised withdrawals attract a 25% charge. The charge applies to the withdrawal, so it is not simply a cancellation of the bonus. Keeping the funds for a permitted later-life withdrawal may be an alternative, but it does not solve an immediate deposit shortfall.

Existing Help to Buy ISA holders also need to choose the appropriate bonus route. HMRC does not allow a buyer to combine that scheme’s government bonus with a charge-free Lifetime ISA first-home withdrawal. For separate savings needed during the move, check notice-account withdrawal restrictions before treating a balance as immediately available.
