The catches are real, though: the £450k property cap excludes much of the South East, and the penalty for non-qualifying withdrawals removes more than just the bonus.\n\nHere's the practical 2026 guide.\n\n## What changed in 2026\n\n- **Property cap held at £450,000 since 2017** — UK average house price grew roughly 35% over that period. The cap now excludes a meaningful share of London and South East starter homes.\n- **Cash LISA rates** competitive again at 4.5–5.0% from Skipton, Moneybox — the only two major Cash LISA providers.\n- **Stocks & Shares LISA platforms** include Moneybox, AJ Bell, Hargreaves Lansdown — TER ranges 0.20–0.45% depending on platform and underlying funds.\n\n## Who can open a LISA\n\n- UK resident\n- Age 18–39 at opening\n- Can contribute until age 50\n- One LISA per person per provider; can split your £4,000 across cash and stocks if you want — though the bonus is the same regardless\n\n## How the bonus works\n\n- Contribute up to £4,000 per tax year\n- Government adds 25% bonus the following month (so April 2026 contribution earns the bonus by mid-May)\n- Bonus is paid into the LISA itself; it then grows alongside your contribution\n\nIf you start at age 22 and contribute £4,000/year through age 50, that's:\n- £112,000 of your contributions\n- £28,000 in government bonus\n- Plus growth on both\n\nAt a 7% real return over 30 years, the £140,000 of contributions+bonus could compound to £400,000+ for retirement (or be drawn down earlier for a home purchase).\n\n## Qualifying uses\n\n1. **First home purchase** — property must be ≤ £450,000, you must be a genuine first-time buyer (no prior property ownership anywhere globally), buying with mortgage. Funds withdrawn 12+ months after first contribution; sent directly to conveyancer.\n2. **At age 60+** — withdraw for any reason, no penalty.\n3. **Terminal illness** — penalty waived.\n4. **On death** — penalty doesn't apply; passes to estate.\n\n## Non-qualifying withdrawal — the penalty math\n\nWithdraw for any other reason and you pay 25% penalty on the *total balance*, not just the bonus.\n\nIf you contributed £4,000 and got £1,000 bonus (£5,000 total), and then need to withdraw early:\n- 25% penalty: £1,250\n- You receive: £3,750\n- Net loss vs contribution: £250 (6.25% effective penalty)\n\nSo the penalty isn't just \"give back the bonus.\" It's \"give back the bonus plus a bit more.\" Plan accordingly.\n\n## LISA vs SIPP — which to fund\n\nFor first-time buyers under 40:\n- **LISA wins** if you'll genuinely buy a home in the next 5–10 years and the property fits the £450k cap.\n- **SIPP wins** for higher-rate taxpayers because 40% relief beats 25% bonus, even if you have to wait until 57 to access.\n\nIf you're certain you'll buy, but unsure if it'll fit the cap, run both. Worst case at LISA: you get 25% bonus on contributions but suffer the 6.25% penalty if you can't use it for the home → still net positive vs not contributing at all.\n\n## Cash LISA vs Stocks & Shares LISA\n\n- **Cash LISA**: 4.5–5.0% interest (May 2026), FSCS protected. Right for a near-term (1–4 year) home deposit.\n- **Stocks & Shares LISA**: market-linked. Right for retirement-focused contributions or 7+ year horizon. Drawdown risk if used for short-term home deposit.\n\nIf your home purchase timeline is uncertain, split — half cash, half S&S.\n\n## Comparison: LISA vs other options\n\n| Option | Annual limit | Bonus / Tax relief | Withdrawal flexibility |\n| --- | --- | --- | --- |\n| LISA | £4,000 | 25% bonus | First home or age 60 |\n| Stocks & Shares ISA | £20,000 (incl. LISA) | None | Anytime, tax-free |\n| SIPP | £60,000 (subject) | 20–45% relief | Age 55 (57 from 2028) |\n| Help to Buy ISA (closed) | (closed to new applicants) | 25% bonus | First home only |\n\n## What to actually do\n\n1. **If you're 18–39 and plan to buy a first home in 5–10 years** — open and max LISA. £4k/year × 25% = £1k/year of free money.\n2. **If you're a higher-rate taxpayer** — fund SIPP first up to your relief, then LISA, then ISA.\n3. **If you're 40+** — LISA isn't open to new applicants. Use ISA + SIPP combinations instead.\n\n## FAQ\n\n**Can my partner and I both have a LISA for one purchase?**\nYes — both partners qualifying as first-time buyers can use their LISAs toward one purchase. £8k/year of contributions × 25% = £2k/year of bonus.\n\n**Does the £450k cap count price or what we pay?**\nPurchase price. Includes any premium for fixtures/fittings if treated as part of the price.\n\n**What if my house price slightly exceeds £450k?**\nDon't qualify. You can withdraw with the 25% penalty and use net for the deposit, but that's almost always worse than just having had the cash in an ISA.\n\n## Where to go next\n\nFor related guides see [ISA vs SIPP UK in 2026](/blog/isa-vs-sipp-uk-2026), [Best UK investment apps for 2026](/blog/best-uk-investment-apps-2026), and [How to buy your first house in 2026](/blog/how-to-buy-first-house-2026).","hue":286,"metaTitle":"Lifetime ISA Guide 2026: Bonus, Property Cap, Drawbacks","metaDescription":"Lifetime ISA in 2026 — how the government bonus works, eligibility, the £450k property cap problem, and when LISA beats SIPP for first-time buyers.","keywords":["lifetime isa guide 2026","lifetime isa bonus","lisa property cap","first time buyer isa","lisa eligibility","lisa withdrawal penalty","lisa vs help to buy","lisa vs sipp","lisa for retirement","cash lifetime isa"],"tldr":["**The Lifetime ISA pays a 25% government bonus on contributions up to £4,000 per year** — so up to £1,000/year free for ages 18–39 (contributions allowed till 50).","**Property cap is £450,000** — set in 2017 and unchanged since.
