Lifetime ISA UK 2026/27: First-Home Rules & What’s Changing

Last updated: October 2026 · General information only, not financial advice. Lifetime ISA rules are changing, so check GOV.UK before you open or withdraw.

A Lifetime ISA can be one of the best ways to save for your first home in the UK. The government adds 25% to what you pay in, which is up to £1,000 of free money every year. But it comes with strict rules, a withdrawal charge that can cost you more than the bonus, and some big news: the government plans to replace it with a new First Time Buyer ISA.

In this guide I’ll walk you through how the Lifetime ISA works for first-time buyers, the rules you must meet, how the 25% charge really works, who it suits (and who it doesn’t), and what the new First Time Buyer ISA means if you’re thinking of opening one now.

What is a Lifetime ISA?

A Lifetime ISA (LISA) is a type of ISA designed to help you do one of two things: buy your first home or save for later life. Here are the key rules from GOV.UK:

After you turn 50, you can’t pay in or earn the bonus any more, but the account stays open and any money in it can keep earning interest or growth.

How the 25% bonus works (with examples)

For every £4 you pay in, the government adds £1. So:

• Save £50 a month (£600 a year) and you get a £150 bonus
• Save £200 a month (£2,400 a year) and you get a £600 bonus
• Save £333.33 a month (£4,000 a year) and you get the maximum £1,000 bonus

If you saved the full £4,000 a year for 5 years, that’s £20,000 of your money plus £5,000 in bonuses, so £25,000 before any interest or growth. If you’re buying with a partner who’s also a first-time buyer, you can each have a Lifetime ISA and both use it for the same home.

Lifetime ISA first-home rules: what you must meet

To use your Lifetime ISA for your first home without a charge, GOV.UK says all of these must apply:

1. The home costs £450,000 or less.
2. You buy at least 12 months after your first payment into the Lifetime ISA.
3. You use a conveyancer or solicitor to act for you.
4. You’re buying with a mortgage. A private loan from family doesn’t count.

You also need to be a first-time buyer, which means you’ve never owned a home, anywhere in the world. Your conveyancer or solicitor asks your Lifetime ISA provider for the money, and it goes to them, not to you.

The £450,000 cap is the one to watch. It hasn’t changed since the Lifetime ISA launched in 2017, and in some areas, especially London and the South East, first homes can cost more. If there’s a real chance yours will cost more than £450,000, a Lifetime ISA may not be right for your deposit.

The 25% withdrawal charge (and why it costs more than the bonus)

This is the part most people misunderstand. If you take money out for any reason other than a first home, being 60 or over, or being terminally ill with less than 12 months to live, you pay a 25% withdrawal charge.

That sounds like it just takes back the bonus. It doesn’t. It takes 25% of the whole amount, including the bonus. Here’s GOV.UK’s own example:

• You pay in £800
• The government adds a £200 bonus, so you have £1,000
• You withdraw it, and the 25% charge is £250
• You get £750 back, which is £50 less than you put in

That’s why I’d only use a Lifetime ISA for money you’re confident will go towards a qualifying first home (or that you’re happy to leave until 60).

Is a Lifetime ISA worth it? Who it suits

It could suit you if:

• You’re 18 to 39 and definitely want to buy your first home
• You expect your home to cost under £450,000
• You’re likely to buy at least 12 months from now
• You’ll be buying with a mortgage
• You’ve already got an emergency fund elsewhere, so you won’t need to dip into it

It might not suit you if:

• You might buy above £450,000
• You’re not sure you’ll buy at all, and might need the money for something else
• You’re buying in less than 12 months
• You’re planning to buy without a mortgage
• You don’t have any other savings for emergencies

Cash Lifetime ISA or Stocks and Shares Lifetime ISA?

You can choose a Cash Lifetime ISA, which earns interest, or a Stocks and Shares Lifetime ISA, where your money is invested. The bonus is the same either way.

• Buying in the next few years? Cash is usually the safer choice, because your deposit can’t fall in value just before you need it.
• Saving for later life, or buying a long way off? Some people choose investments for the chance of more growth, accepting that the value can go down as well as up.

Lifetime ISAs keep their separate £4,000 annual contribution limit within the overall £20,000 ISA allowance. The April 2027 £12,000 Cash ISA limit applies to ordinary Cash ISAs, not Cash Lifetime ISAs. My ISAs explained guide covers that change.

Big change: the new First Time Buyer ISA

In June 2026 the government published a consultation on a new First Time Buyer ISA, which it plans to offer instead of the Lifetime ISA. It says the Lifetime ISA is too complicated and that many people end up paying the withdrawal charge.

Here’s what the consultation proposes (these are proposals, not final rules):

• No withdrawal charge. If your plans change, you can take your money out without a penalty. You just don’t get the bonus.
• No upper age limit. You could open one at 18 or over, including after 40.
• The bonus is paid when you buy your first home with a mortgage, based on what you’ve paid in (minus withdrawals), not on growth. The account must be open for at least 12 months.
• Cash and investment versions, with cash counting towards the £12,000 Cash ISA limit.
• Not yet decided: the bonus rate, the yearly limit, the house price cap and the launch date. The government says these will be set at a future Budget.

What happens to existing Lifetime ISAs?

• You can still open a Lifetime ISA until the new account is available.
• If you already have one, the government says you can keep saving into it under the current rules indefinitely.
• You can’t transfer a Lifetime ISA into the new First Time Buyer ISA, but you could use money from both for the same home. You’d only be able to pay into one of them in each tax year.

So should you open a Lifetime ISA now, or wait?

There’s no single answer, but here’s how I’d think about it. Opening a Lifetime ISA now starts your 12-month clock and makes qualifying contributions eligible for the 25% bonus under the current rules, under rules we know. Waiting means you might get a more flexible account with no withdrawal charge, but we don’t yet know when it’ll launch or how generous the bonus will be. If you’re confident you’ll buy under £450,000 with a mortgage, the known bonus today is hard to ignore. If you’re unsure whether you’ll buy at all, the flexibility of the new account may be worth waiting for. I’ll update this section when the details are announced.

How to use your Lifetime ISA when you buy

1. Tell your conveyancer or solicitor early that you’ll use a Lifetime ISA.
2. They request the money from your provider when you’re close to completion.
3. The money goes to your conveyancer, not to you, and is used for the purchase.
4. Leave plenty of time. Ask your provider how long it takes to release the money.

Budget for the other buying costs too, like the survey, solicitor and moving. My hidden costs of buying a house guide lists them all, and the bank statements for a mortgage guide helps you get mortgage-ready.

Lifetime ISA mistakes to avoid

1. Opening it too late. You need 12 months between your first payment and buying.
2. Forgetting the £450,000 cap when house hunting.
3. Using it as an emergency fund. The 25% charge can leave you with less than you paid in.
4. Paying into two Lifetime ISAs in the same tax year. You can only pay into one.
5. Not telling your conveyancer until the last minute.

Lifetime ISA for first-time buyers: FAQs (UK)

Can I still open a Lifetime ISA in 2026?

Yes. The government says you can still open one until the new First Time Buyer ISA is available. You must be 18 to 39.

What happens if my house costs more than £450,000?

You can’t use your Lifetime ISA for it without paying the 25% withdrawal charge. You could keep the money in the Lifetime ISA until you’re 60 instead.

Can my partner and I both use a Lifetime ISA?

Yes. If you’re both first-time buyers and both meet the rules, you can both use your Lifetime ISA savings and bonuses for the same home.

Can I use a Lifetime ISA with a Help to Buy ISA?

You can have both, but GOV.UK says you can only use the government bonus from one of them for your home.

Will my Lifetime ISA be closed when the new account launches?

Based on the consultation, no. The government says existing holders can keep saving under the current rules indefinitely.
