Lifetime ISA Investment Options: Cash or Stocks and Shares?

A Lifetime ISA can hold cash, stocks and shares, or a combination of both, according to gov.uk. A cash version earns interest and does not move with markets, while a stocks and shares version can rise or fall in value. The 25% government bonus, the £4,000 limit for the 2026-27 tax year and the withdrawal rules are the same for both forms.

The site's rules data was last checked against gov.uk on 26 September 2026. Figures typed in this guide may not yet reflect a later change, and the descriptions of gov.uk pages are summaries that may also lag. The current figures are on the ISA rules at a glance page. General information only, not financial advice.

What can a Lifetime ISA hold?

gov.uk says you can hold cash or stocks and shares in your Lifetime ISA or have a combination of both (GOV.UK Lifetime ISA overview). The same page says you can put in up to £4,000 each year until you are 50, and that the government adds a 25% bonus, up to a maximum of £1,000 per year. The page gives one limit and one bonus for the Lifetime ISA, not separate figures for cash and stocks and shares. gov.uk says you must be 18 or over but under 40 to open one (who can open a Lifetime ISA).

Money can leave the account without the charge in three situations: buying a first home (property of £450,000 or less, bought at least 12 months after the first payment), being 60 or over, or terminal illness with less than 12 months to live. Other withdrawals attract a 25% charge (withdrawing money from your Lifetime ISA). These rules apply whichever form is held.

How does a cash Lifetime ISA work?

A cash Lifetime ISA works like a savings account inside the ISA wrapper: the money earns interest at a fixed or variable rate set by the provider, and the balance does not move with markets, subject to the provider's terms and any FSCS cover. The pages read for this guide do not say whether a given Lifetime ISA is covered by the FSCS, so ask the provider or FSCS (its investments page does not mention ISAs).

The trade-off is that interest may not keep pace with inflation over long periods, and rates change. Cash Lifetime ISA rates vary between providers and over time, so this guide does not quote a current figure.

How does a stocks and shares Lifetime ISA work?

A stocks and shares Lifetime ISA invests the money paid in, and the bonus, in financial markets. What can be held depends on the provider. Some offer a short list of ready-made portfolios labelled by risk level, some offer a wider range of funds, and some allow individual shares. Options that providers may list include:

tracker or actively managed funds;
mixed-asset funds that combine shares, bonds and other assets;
ethical or ESG-screened funds;
individual shares, with some providers.

The value can fall as well as rise, and past performance is not a reliable indicator of future results. The bonus does not protect against a fall in value.

A worked example: cash and stocks and shares compared

The figures are assumptions for the arithmetic, not forecasts and not statements about any provider. A saver pays £1,200 a year into a Lifetime ISA for 10 years. The bonus at 25% is £300 a year, so £1,500 goes in each year. Payments are assumed to arrive at the end of each year and growth to compound annually, with results rounded to the nearest pound.

Money in over 10 years: £1,500 × 10 = £15,000.
Cash at an assumed 3.5% a year: about £17,597.
Stocks and shares at an assumed 6% a year after charges: about £19,771.
Difference: £2,174.

A stocks and shares result is not fixed. If the value fell by 20% at the end of year 10, the £19,771 would become about £15,817, which is below the cash result and only a little above the £15,000 that went in. A fall during the saving period, or just before the money is needed, can therefore change the picture. The Lifetime ISA calculator can run other amounts and assumed rates, and its results are illustrations, not forecasts.

How can providers be compared?

Points that differ between providers:

Charges. Platform charges and fund charges vary. Using the same example, if the assumed 6% were 5.5% because of a 0.5 percentage point higher charge, the 10-year result would be about £19,313, which is £458 less. Small differences in charges compound over time.
Fund range. Whether the provider offers the kinds of investments being looked for.
Ease of use. Whether the platform is straightforward, particularly for a first-time investor.
Withdrawal process. For a home purchase, gov.uk says the ISA provider pays the funds directly to the buyer's conveyancer or solicitor, so how the provider handles that is worth asking about.
Bonus timing. The pages read do not say when the bonus is credited, so ask each provider.

Availability, charges and fund ranges change, so check current terms with any provider.

Can the account be moved between forms?

gov.uk says that moving a Lifetime ISA to another type of ISA before 60 triggers the 25% withdrawal charge. The pages read do not say how a switch from a cash Lifetime ISA to a stocks and shares Lifetime ISA, or the reverse, is treated. gov.uk's transferring your ISA page says there are restrictions on the transfers you can make if you have a Lifetime ISA, without describing them. Ask the provider before moving.

What is not guaranteed?

Investment returns on a stocks and shares Lifetime ISA.
The rate on a cash Lifetime ISA, which can change.
The bonus rate, the limits and the property cap, which are set by the government and can change.
Charge-free access outside the three situations above.

The £4,000 limit is lower than the overall ISA allowance of £20,000, and counts towards it. The Lifetime ISA is not described by gov.uk as a pension, and the pages read do not compare the two.

What to check and questions to ask a provider

Is the account cash, stocks and shares, or both, and what can it hold?
What are the charges, both platform and fund?
Is the interest rate fixed or variable, and for how long?
When is the bonus credited?
How does the withdrawal process work for a first-home purchase?
Can the account be moved between a cash and a stocks and shares version, and would the withdrawal charge apply?
Is the account covered by the FSCS?

Frequently asked questions

Can a Lifetime ISA hold cash and investments together?

Yes. gov.uk says a Lifetime ISA can hold cash or stocks and shares, or a combination of both. The same limit of £4,000 and the same bonus apply.

Are cash Lifetime ISAs covered by the FSCS?

The pages read for this guide do not say. FSCS cover depends on the provider and the account, so ask the provider or FSCS about a particular Lifetime ISA.

Can I switch from a cash to a stocks and shares Lifetime ISA?

gov.uk says moving a Lifetime ISA to another type of ISA before 60 triggers the 25% charge. The pages read do not say how a switch between the two Lifetime ISA forms is treated, so ask the provider first.

Can a stocks and shares Lifetime ISA lose money?

Yes. The value can fall as well as rise, and the bonus does not protect against a fall. In the worked example, a 20% fall at the end of 10 years reduced the result to about £15,817.
