Lifetime ISA vs Help to Buy ISA is a comparison that matters for UK first-time buyers who already hold a Help to Buy ISA or are deciding how to save for a future deposit. Both schemes were created to support first-home buyers and both offer a 25% government bonus, but they have different rules, deadlines, property price caps and contribution limits. This article explains how the two compare, what UK readers should know about their continued availability, and which scenarios may suit each. It is general financial education and not personal advice, drawing on GOV.UK and MoneyHelper guidance.

Rules and figures can change at fiscal events, and the Help to Buy ISA programme has firm closing deadlines. Figures referenced should be verified against the latest official guidance before acting.

What is a Lifetime ISA?

A Lifetime ISA, or LISA, is an Individual Savings Account for UK residents aged 18 to 39 designed to support first-home purchases and later-life saving. Up to £4,000 a year can be contributed, attracting a 25% government bonus of up to £1,000 per tax year. Funds can be withdrawn penalty-free for a qualifying first-home purchase up to £450,000 or from age 60. Other withdrawals usually trigger a 25% government Withdrawal charge.

What is a Help to Buy ISA?

A Help to Buy ISA, or HTB ISA, is a savings account introduced in 2015 to help first-time buyers save for a deposit. Up to £200 a month can be contributed, plus a £1,000 initial deposit, with a 25% government bonus paid at the point of property completion. The HTB ISA closed to new applicants on 30 November 2019, but existing holders can continue to save until 30 November 2029 and must claim the bonus by 1 December 2030. The minimum government bonus is £400 (on £1,600 of savings), and the maximum is £3,000 (on £12,000 of savings).

Lifetime ISA vs Help to Buy ISA: side-by-side comparison

How do the property price caps differ?

The Lifetime ISA has a single property price cap of £450,000 for any UK first-home purchase, regardless of region. The Help to Buy ISA has a £250,000 cap for properties outside London and a £450,000 cap for properties in London. This makes the LISA cap higher than the HTB ISA cap outside the Capital and matching it within London.

First-time buyers in higher-cost areas outside London may find the LISA cap more accommodating than the HTB ISA, while buyers under the £250,000 threshold may use either scheme based on other features.

How is the government bonus paid?

The Lifetime ISA bonus is paid by HMRC into the LISA on a monthly basis as providers submit data, building up alongside contributions and Investment growth. It is available for first-home purchase or for use from age 60. The Help to Buy ISA bonus is paid at the point of property completion. The conveyancer applies for the bonus after the saver closes the HTB ISA, and the bonus is paid into the property purchase, not directly to the buyer.

This means a LISA bonus can be invested and potentially grow inside a Stocks and Shares LISA, while a HTB ISA bonus has no opportunity to grow before it is applied to the purchase.

How do withdrawal rules differ?

Withdrawals from a Lifetime ISA that are not for a qualifying first-home purchase or after age 60 usually attract a 25% government withdrawal charge, which can reduce the amount received below the original contribution. Withdrawals from a Help to Buy ISA can be made at any time without a penalty, but the 25% government bonus is only paid where the funds are used towards a qualifying first-home purchase. Non-qualifying use of HTB ISA savings simply forfeits the bonus.

Can someone hold both a Lifetime ISA and a Help to Buy ISA?

Yes, both can be held at the same time, although the rules limit how both bonuses can be used. Only one scheme's bonus can be claimed for a single property purchase. Some savers have used the HTB ISA bonus for the property completion and transferred their HTB ISA balance into a LISA before claiming, but the rules require care and should be checked with both providers and GOV.UK before action.

What about transfers between HTB ISA and LISA?

Transfers from a Help to Buy ISA into a Lifetime ISA are permitted. The transferred amount counts towards the £4,000 annual LISA contribution limit and the £20,000 ISA allowance, and qualifies for the 25% bonus. Some savers have done this to consolidate balances or to take advantage of the LISA's higher annual contribution capacity. Transfers should be initiated through the LISA provider.

Which buyers may find the LISA more useful?

The LISA may suit UK residents aged 18 to 39 who are saving for a first home up to £450,000, particularly outside London where the HTB ISA's £250,000 cap may be lower than local property prices. The LISA also offers the option to keep the bonus for retirement saving from age 60, providing flexibility. Stocks and Shares LISAs allow investment of the bonus and contributions for those with a longer horizon. Returns inside a Stocks and Shares LISA can rise or fall.

Which buyers may find an existing HTB ISA more useful?

Existing Help to Buy ISA holders saving for a home under the relevant price cap, with a target completion before the 1 December 2030 bonus deadline, may find the HTB ISA still useful. There is no 25% withdrawal charge if plans change. The HTB ISA bonus is also paid at completion rather than monthly, which can suit some savers.

Hypothetical example of LISA vs HTB ISA

A hypothetical UK first-time buyer aged 28 already holds a HTB ISA with £6,000 and wants to buy a £350,000 home outside London. The HTB ISA bonus would not apply because the property price is above the £250,000 cap outside London. The buyer could transfer the HTB ISA balance into a LISA, which has a £450,000 cap, and receive the 25% bonus on the transferred amount. This is illustrative only and not a recommendation, and outcomes depend on individual circumstances and the latest GOV.UK rules.
