Quick answer
The Lifetime ISA lets you save up to £4,000 a year with the government adding a 25% bonus — up to £1,000 of free money annually — towards your first home (or retirement from 60). The catches are real: you must open it between 18 and 39, the account needs to be open 12 months before you buy, the property must cost £450,000 or less and be bought with a mortgage, and withdrawing for anything else triggers a 25% penalty that takes the bonus plus around 6.25% of your own money. Big changes are coming: following a consultation launched on 23 June 2026, the LISA will be replaced by a new First-Time Buyer ISA from around April 2028 — no upper age limit, no withdrawal penalty — but existing LISAs continue indefinitely, and you can still open one now (many savers open one with a small amount today just to start the 12-month clock). Rules as of July 2026.
Your home may be repossessed if you do not keep up repayments on your mortgage.

How the Lifetime ISA works
The LISA is the most generous savings incentive available to under-40s — and the one with the sharpest edges. The core rules as of July 2026:
| Rule | Detail |
|---|---|
| Who can open one | UK residents aged 18–39 (you can keep paying in until 50) |
| Annual limit | £4,000 per tax year — counts within your overall £20,000 ISA allowance |
| Government bonus | 25% on everything you pay in — up to £1,000 a year, paid monthly, which then earns interest or growth itself |
| Types | Cash LISA (savings interest) or Stocks & Shares LISA (invested — better suited to longer horizons) |
| Penalty-free uses | A first home costing £450,000 or less (account open 12+ months), or withdrawal from age 60 |
| Anything else | 25% government withdrawal charge on the amount taken out |
You can hold a LISA alongside a cash ISA, a stocks & shares ISA and the rest of the family in the same tax year — the £4,000 simply eats into the shared £20,000 allowance. Couples get a quiet superpower here: the limits are per person, so two first-time buyers can each run a LISA and put both pots plus both bonuses toward the same home.
The bonus maths: what the 25% is actually worth
Worked example
Save the full £4,000 a year for four years: you’ve put in £16,000, the government has added £4,000, and every monthly bonus instalment has been earning interest along the way — call it £20,500–£21,000+ in a decent cash LISA. A couple doing the same both hit that: £8,000 of free money on £32,000 saved, before interest. Against Portsmouth- or Leicester-level first-time buyer prices, four years of two-person LISA saving essentially is a 10% deposit — with the state contributing a fifth of it.
The strategic implication of monthly bonus payment is worth noting because the replacement scheme changes it (below): under the current LISA, bonuses compound from the month they land. Savers on multi-year timelines get meaningfully more than the headline 25% by the time they buy.
Using it to buy: the rules and the process
Every condition must be met to withdraw penalty-free for a purchase:
- Genuine first-time buyer: you’ve never owned property anywhere in the world — including inherited property or a share of one.
- £450,000 cap: the home must cost £450,000 or less. Even £1 over and the withdrawal is penalised (more below).
- 12-month rule: the LISA must have been open at least 12 full months. Find your dream home in month ten and the funds are effectively locked behind the penalty — the reason for the “open one with £1 today” tactic.
- Mortgage required: the purchase must use a residential mortgage — not cash, and not a buy-to-let mortgage.
- UK property, and you must intend to live in it.
The process itself runs through your conveyancer: they request the funds and bonus from your LISA provider and apply them at purchase — the money goes solicitor-to-purchase, not into your bank account. Build in a couple of weeks of lead time when your purchase is heading to exchange, and tell your broker and solicitor early that LISA funds are involved.
One rule that surprises couples: buying jointly with someone who isn’t a first-time buyer doesn’t block you from using your LISA, provided you qualify and the property is under £450,000. That’s the opposite of first-time buyer stamp duty relief, where a single non-first-timer on the purchase disqualifies everyone — the two schemes test the same words differently, and mixing them up is a common (expensive) assumption.
The withdrawal penalty — and the reform that’s finally fixing it
Here’s the maths most people only run after it’s cost them. The 25% charge applies to the whole withdrawal — your contributions and the bonus together — and because the bonus only makes up 20% of your pot, the charge claws back more than the government ever gave you:
| Step | Amount |
|---|---|
| You save | £4,000 |
| Government adds 25% | +£1,000 → pot is £5,000 |
| You withdraw for a non-qualifying reason: 25% charge | −£1,250 |
| You receive | £3,750 — £250 less than you paid in |
That’s a 6.25% loss of your own money, and it applies whatever the reason: emergency, house purchase falling through, buying over £450,000, or simply needing the cash. There’s no hardship exemption — the only penalty-free exits are a qualifying home purchase, age 60, or terminal illness. This structural sting is exactly what the reform addresses:
The reform: LISA out, First-Time Buyer ISA in (April 2028)
Following the Autumn Budget 2025 announcement, the government launched its consultation on the replacement First-Time Buyer ISA on 23 June 2026 (running to 18 August). What’s confirmed or proposed so far: the withdrawal penalty is scrapped — you’d access your own money freely, forfeiting only the bonus; no upper age limit (the LISA’s 18–39 gate goes); the retirement element is removed — it’s a pure first-home product; and the bonus would be paid as a lump sum at purchase rather than monthly, which means no compounding on bonuses while you save — a genuine downgrade hidden in the good news. Whether the £450,000 cap rises is still unanswered. Meanwhile: existing LISAs continue indefinitely — contributions, bonuses and all — you can still open one right up to launch, and LISA balances won’t be transferable into the new account (Help to Buy ISA balances will). We’ll update this guide as the consultation concludes.
So should you still open a LISA now? For most people saving toward a first home, yes: two more tax years of 25% bonuses with monthly compounding beat waiting for 2028, and opening with even £1 today starts the 12-month clock. The main caution is certainty — if there’s a real chance you won’t buy (or will buy over £450,000), the penalty means a LISA can cost you money where an ordinary ISA can’t. That’s the trade the reform exists to fix; until 2028, it’s still yours to weigh.

The £450,000 problem
The property cap has been frozen since the LISA launched in 2017, while average UK prices have risen by roughly a third — a squeeze felt hardest in London and the South East, where ordinary first homes now brush the limit. The cliff-edge is absolute: buy at £450,001 and your withdrawal is non-qualifying, triggering the full penalty on money you saved specifically to buy a home. Savers near the line have three honest options: target sub-cap properties (the cap is on price, not postcode ambition), use the LISA pot without the penalty by keeping it for retirement and funding the deposit another way, or accept the penalty knowingly where the home matters more than the charge. The Treasury Select Committee has called for the cap to rise and the 2026 consultation is reviewing it — but as of July 2026, £450,000 stands, and planning should assume it does.
LISA vs Help to Buy ISA: the handover
The Help to Buy ISA — the LISA’s predecessor — closed to new savers in 2019, but existing holders can keep contributing until 2029, so plenty of buyers still hold both questions in one head:
| Lifetime ISA | Help to Buy ISA (existing holders) | |
|---|---|---|
| Bonus | 25%, up to £1,000/year, paid monthly | 25%, capped at £3,000 total, paid at purchase |
| Save per year | £4,000 | £200/month (£2,400/year) |
| Property cap | £450,000 UK-wide | £250,000 (£450,000 in London) |
| Bonus usable for exchange deposit | Yes — funds released to your conveyancer | No — bonus arrives at completion only |
| Future | Replaced April 2028; accounts continue | Transferable into the new FTB ISA at launch |
For most savers who qualify for both, the LISA wins on every line that matters — higher limits, bigger total bonus, higher cap outside London. You can only use the government bonus from one scheme per purchase, though a common play is transferring HTB ISA savings into a LISA (it uses your £4,000 annual allowance) to consolidate. And when the FTB ISA launches, HTB ISA money gets a transfer route in — LISA money doesn’t.
Over 40? Your options while the age gate lasts
Turn 40 without a LISA and the door is currently closed — one of the scheme’s most criticised rules given the average first-time buyer’s age keeps rising. The incoming FTB ISA removes the age limit entirely, which is genuinely good news for over-40 savers — but it’s an April-2028 fix. Until then the practical toolkit is: ordinary ISAs for tax-free saving (no bonus, no penalty), family gifted deposits, shared ownership to shrink the deposit needed, and the low-deposit routes in our no-deposit mortgage guide. And if you’re 39, the maths is simple: open the LISA now — beat the birthday, keep contributing until 50.
Fitting the LISA into your mortgage plan
The LISA is deposit-side; the mortgage is the other half, and the two interact more than savers expect:
- Time the 12-month rule against your buying timeline — and remember the funds route via your conveyancer, so the money isn’t in your account for proof-of-deposit; lenders and brokers handle LISA-funded deposits routinely, just declare it early.
- A LISA deposit combines happily with a gifted deposit, personal savings, and (for eligible buyers) schemes like shared ownership or First Homes — the full menu is in our first-time buyer schemes guide.
- Know your borrowing before you set your target. A £25,000 pot means nothing without knowing the mortgage it anchors — get the realistic figure from our borrowing guide, then a mortgage in principle when you’re within a few months of buying.
- The whole journey — from savings account to keys — is mapped in our complete first-time buyer guide.
The bottom line
The Lifetime ISA remains the best deal in first-home saving — 25% free money, compounding monthly — wrapped in rules that punish the unwary: a 12-month lock, a frozen £450,000 cap, and a penalty that takes 6.25% of your own money if life changes your plans. The 2026 reform fixes the penalty and the age gate, but not until April 2028, and at the cost of bonus compounding — so for most committed first-time savers, the move is still: open now, start the clock, take the bonuses while they compound.

Lifetime ISA: FAQs
Is a Lifetime ISA worth it in 2026?
For most people genuinely saving toward a first home under £450,000: yes — a guaranteed 25% bonus with monthly compounding is unmatched by any savings account, and two more tax years of bonuses remain before the replacement scheme launches. The caution is commitment: if there’s a real chance you won’t buy, or will buy above the cap, the 25% withdrawal charge means you’d get back less than you put in — around 6.25% of your own money lost. Certain savers win big; uncertain savers should weigh the penalty honestly or use an ordinary ISA.
What happens to my Lifetime ISA when the new First-Time Buyer ISA launches?
Nothing bad. Existing LISAs continue indefinitely after the FTB ISA launches (expected April 2028) — you keep contributing, keep receiving the 25% bonus, and keep the retirement option. You can also still open a new LISA any time before launch. Two details to know: LISA balances won’t be transferable into the new account (Help to Buy ISA balances will), and the new scheme pays its bonus as a lump sum at purchase rather than monthly, so current LISA savers keep the better compounding deal.
Can I have a Lifetime ISA and a cash ISA at the same time?
Yes. You can pay into a LISA alongside cash and stocks & shares ISAs in the same tax year — the £4,000 LISA limit simply counts within your overall £20,000 annual ISA allowance. You can only hold and pay into one LISA per tax year, though, and only one scheme’s government bonus can be used per home purchase.
Can I use a Lifetime ISA to buy with my partner if they’ve owned before?
Yes — this is one of the LISA’s friendliest rules. Your partner’s ownership history doesn’t affect your entitlement: if you personally qualify as a first-time buyer, you can use your LISA and bonus toward a joint purchase, provided the property costs £450,000 or less. Note the contrast with first-time buyer stamp duty relief, where every buyer on the purchase must qualify — couples in this position often keep the LISA bonus but lose the stamp duty relief, which is worth budgeting for.
Can I use a Lifetime ISA for a buy-to-let?
No. A qualifying LISA purchase must be your first home, bought with a residential mortgage, with the intention of living in it — buy-to-let purchases (and cash purchases) don’t qualify, so using LISA funds for one means taking the 25% withdrawal charge. The only penalty-free alternative uses are withdrawal from age 60 or terminal illness. If property investment is the goal, save in a standard ISA instead and see our buy-to-let guides for the lending side.
What happens if the house I’m buying costs more than £450,000?
The withdrawal becomes non-qualifying and the full 25% charge applies — even at £450,001, and even though you’re using the money for exactly the purpose the scheme intended. Your options near the line: target homes under the cap, leave the LISA untouched for retirement and fund the deposit another way, or take the penalty as a known cost of the home you want. The government is reviewing the frozen cap as part of the 2026 consultation, but no increase has been confirmed.
