Lifetime ISA vs Help to Buy ISA: Which Is Better?

If you are saving for your first home in the UK, you have probably come across two government-backed savings schemes: the Lifetime ISA (LISA) and the Help to Buy ISA. Both offer a 25% bonus on your savings to help you build a deposit, but they work differently and suit different situations. This guide compares them in detail so you can decide which is right for you — or whether you should use both.

How the Lifetime ISA Works

The Lifetime ISA was introduced in April 2017 and is available to anyone aged 18-39. You can contribute up to £4,000 per tax year, and the government adds a 25% bonus on your contributions - up to £1,000 per year. The government pays the bonus annually in April.

You can use the LISA bonus for one of two purposes: buying your first home (the property must cost £450,000 or less) or retirement (you can withdraw after age 60). If you withdraw for any other reason, you face a 25% penalty on the amount withdrawn, which actually means you lose more than just the bonus - you lose 6.25% of your own contributions too. Note that the LISA scheme is currently under government consultation.

LISAs are available as cash LISAs (earning interest like a savings account) or stocks and shares LISAs (invested in the market). For a house deposit that you will need within the next few years, a cash LISA is generally safer. A stocks and shares LISA may suit you if your timeline is longer than five years or if you plan to use it primarily for retirement.

One important rule: your LISA must be open for at least 12 monthsbefore you can use the funds for a property purchase. This means you should open one as soon as possible, even with a small initial deposit, to start the clock.

How the Help to Buy ISA Works

The Help to Buy ISA was launched in December 2015 and closed to new applicants in November 2019. However, if you already have one open, you can continue to save into it until November 2029 and claim the bonus until November 2030.

With a Help to Buy ISA, you can save up to £200 per month (plus an initial lump sum of £1,000 when you first open the account). The government adds a 25% bonus on your savings, up to a maximum bonus of £3,000 (on £12,000 of savings). This means the most you can receive in bonus money is £3,000, compared to the LISA where there is effectively no lifetime cap.

The Help to Buy ISA bonus is not paid into your account as you save. Instead, it is claimed through your solicitor at the point of completion when you buy your first home. This means the bonus cannot be used as part of your exchange deposit - it only becomes available at the final stage of the purchase. The property price limit is £250,000 outside London and £450,000 in London.

Key Differences at a Glance

Pros and Cons of Each

Lifetime ISA Pros

• Higher annual contribution limit means faster saving
• No cap on lifetime bonus — keep earning £1,000/year until age 50
• Bonus paid annually in April, so it earns interest too
• Can be used for a property up to £450,000 anywhere in the UK
• Dual purpose — can switch to retirement savings if you decide not to buy
• Still open to new applicants

Lifetime ISA Cons

• 25% withdrawal penalty is harsh if you change your mind or need the money
• Must wait 12 months before using for a property - plan ahead
• Cannot be used for properties over £450,000
• Age restriction - must open before age 40

Help to Buy ISA Pros

• No withdrawal penalty - you can take your savings out at any time without losing your own money (you just forfeit the bonus)
• Simpler structure - straightforward savings account
• No minimum holding period for property purchases

Help to Buy ISA Cons

• Closed to new applicants since November 2019
• Much lower contribution limits (£200/month vs £333/month for LISA)
• Total bonus capped at £3,000
• Lower property price limit outside London (£250,000)
• Bonus only available at completion, not at exchange
• Cannot be used for retirement

Can You Have Both?

Yes! If you already have a Help to Buy ISA, you can also open a Lifetime ISA. However, there is an important restriction: you can only use the government bonus from one of them when buying a property. You cannot claim both the LISA bonus and the Help to Buy ISA bonus on the same property purchase.

In most cases, the LISA bonus will be more valuable because there is no cap and the contribution limit is higher. If you have both accounts, you could use the LISA bonus for your property purchase and withdraw your Help to Buy ISA savings (without the bonus) to add to your deposit separately.

Which Scenarios Suit Each Account?

Choose the LISA if:

• You are under 40 and can open a new account
• You want to maximise your government bonus
• You are buying a property under £450,000
• You have at least 12 months before you plan to buy
• You want the option to use it for retirement if your plans change

Keep using your Help to Buy ISA if:

• You already have one open and are close to buying
• You need flexibility — you might need to access the money for other purposes
• You are buying a property under £250,000 outside London and the £3,000 bonus meets your needs
• You cannot wait 12 months for the LISA holding period

Use both if:

• You want to maximise your total savings across multiple accounts
• You plan to use the LISA bonus for your home purchase and withdraw your Help to Buy savings (without bonus) as additional deposit money

Transferring from Help to Buy to LISA

You can transfer funds from a Help to Buy ISA into a LISA, but it counts towards your LISA annual contribution limit of £4,000. The transfer must also be done within the same tax year to count towards that year's allowance. Before transferring, consider whether you might benefit from keeping both accounts — the Help to Buy ISA savings can still be withdrawn without penalty and used towards your deposit, even if you do not claim the bonus from that account.

The Bottom Line

For the vast majority of first-time buyers in 2026, the Lifetime ISA is the better choice. It offers higher contribution limits, a higher overall bonus, and more flexibility with its dual home/retirement purpose. The only scenario where the Help to Buy ISA might edge ahead is if you need immediate access to your savings without penalty or if you are buying very soon and cannot wait for the 12-month LISA holding period.

If you are starting from scratch, open a LISA today - even with just £1 - to get the 12-month clock ticking. Your future self will thank you.
