The Lifetime ISA for First-Time Buyers: How It Works in 2026

A Lifetime ISA (LISA) helps first-time buyers save for a home by adding a 25% government bonus on top of what you pay in — up to £1,000 free each tax year on savings of up to £4,000. You can open one aged 18 to 39 and keep contributing until you turn 50. To use it for a first home the property must cost £450,000 or less, you must be a genuine first-time buyer, and the account must have been open at least 12 months. The catch: withdraw for anything other than a first home or before age 60 and you pay a 25% charge.

In short: the LISA is free government money toward a first home under £450,000 — brilliant if you follow the rules, costly if you break them.

How the Lifetime ISA bonus works

The Lifetime ISA pays a 25% government bonus on your contributions, up to a maximum of £1,000 a year. You can pay in up to £4,000 per tax year, and that £4,000 counts toward your overall annual ISA allowance. The bonus is paid monthly on what you contribute, and it earns interest or investment growth alongside your own money. Because the bonus applies every year you save, starting early and paying in the full £4,000 each year maximises the free money you receive before you buy.

• Pay in up to £4,000 per tax year
• Government adds a 25% bonus — up to £1,000 free per year
• Save the maximum for five years and that is up to £5,000 in bonuses alone
• Your contributions plus the bonus also earn interest or investment growth
• The £4,000 counts toward your total annual ISA allowance

Who is eligible for a Lifetime ISA?

To open a LISA you must be a UK resident aged between 18 and 39. Once open, you can keep paying in — and earning the bonus — until the day before your 50th birthday. To use the money for a first home you must be a genuine first-time buyer, meaning you have never owned a property anywhere in the world. If you are buying with a partner, you can each hold your own LISA and use both toward the same home, doubling the potential bonus, provided you both qualify as first-time buyers.

The £450,000 property cap

The home you buy with LISA funds must cost £450,000 or less, and this cap is the same across the whole UK. If the purchase price is even slightly above £450,000 you cannot use your LISA toward it without triggering the withdrawal charge. In higher-priced areas such as London and the South East, this cap can be limiting, so factor it into where and what you plan to buy before you commit years of saving to a LISA. The property must also be bought with a mortgage, not cash, and become your main residence.

The withdrawal penalty trap to avoid

This is the LISA's sharpest edge. You can withdraw money without penalty only to buy your first home, from age 60 onwards, or if you are terminally ill. Any other withdrawal — an emergency, a change of plan, or buying a home over £450,000 — triggers a 25% government withdrawal charge. Crucially, because the charge is 25% of the amount withdrawn (not just the bonus), it can leave you with less than you originally paid in. Treat LISA money as locked away for your first home, and keep a separate emergency fund elsewhere.

“The 25% withdrawal charge is not the same as losing the 25% bonus — because it applies to the whole withdrawal, it can claw back more than the bonus gave you, leaving you out of pocket on your own savings.”

Cash LISA vs stocks and shares LISA

You can hold your LISA as cash, where it earns interest like a savings account, or as stocks and shares, where it is invested and can rise or fall in value. A cash LISA suits buyers with a short horizon — say, buying within a few years — because the money should not fall in value. A stocks and shares LISA may suit those saving over a longer period who can ride out market ups and downs for potentially higher growth. Either way, the 25% government bonus applies the same. Match the type to when you plan to buy.

LISA vs Help to Buy ISA

The Help to Buy ISA closed to new savers in 2019, so first-time buyers today open a LISA instead. If you still hold a Help to Buy ISA, it is worth understanding the differences. The LISA generally offers a bigger bonus (25% on up to £4,000 a year versus the Help to Buy ISA's lower monthly limits) and a higher property cap outside London. However, you cannot claim the bonus from both schemes toward the same purchase. Anyone holding an old Help to Buy ISA should compare carefully before transferring or choosing which to use.

• Help to Buy ISA closed to new applicants in 2019 — LISA is the current option
• LISA: 25% bonus on up to £4,000/year (up to £1,000 free annually)
• LISA property cap is £450,000 UK-wide
• You cannot use the bonus from both schemes on the same home
• Existing Help to Buy ISA holders should compare before switching

A worked example

Imagine you open a LISA at 25 and pay in the full £4,000 every tax year for five years. You contribute £20,000 of your own money, and the government adds £5,000 in bonuses — before any interest or growth. That £25,000-plus becomes a substantial deposit on a home priced at or below £450,000. A couple who each do the same could combine two LISAs for a deposit of over £50,000 from contributions and bonuses alone, transforming what they can afford and the mortgage rates they can access.

How to open and use a LISA to buy

Opening a LISA is straightforward: choose a cash or stocks and shares provider, confirm you are aged 18 to 39 and a UK resident, and start paying in. Remember the account must have been open at least 12 months before you can use it toward a home, so opening one early — even with a small deposit — starts that clock ticking. When you buy, you do not receive the money yourself; your conveyancer requests the funds directly from your LISA provider and applies them to the purchase on completion. Tell your conveyancer early that you are using a LISA so they can handle the paperwork and timing correctly.

• Open a LISA aged 18–39; keep paying in until age 50
• The account must be open 12+ months before you can use it to buy
• Your conveyancer requests the funds from the provider — you do not withdraw them yourself
• The bonus is included in the money released toward completion
• Tell your solicitor early that a LISA is funding part of the purchase

Common mistakes first-time buyers make with a LISA

The costliest error is treating a LISA like an ordinary savings account and withdrawing in an emergency — the 25% charge can leave you worse off than if you had saved elsewhere. Others open a LISA too late and are caught out by the 12-month rule when they find a home quickly. Some overlook that the £450,000 cap can rule out their target area, and a few forget the money must fund a mortgaged main residence, not a cash purchase or buy-to-let. Keep a separate emergency fund, open the account early, and check the cap against local prices before committing.
