The Lifetime ISA is one of the few unambiguously generous tax-advantaged products in the UK — a 25% government bonus that genuinely is free money for first-time buyers and young retirement savers. 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.
Here's the practical 2026 guide.
What changed in 2026
- 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.
- Cash LISA rates competitive again at 4.5–5.0% from Skipton, Moneybox — the only two major Cash LISA providers.
- Stocks & Shares LISA platforms include Moneybox, AJ Bell, Hargreaves Lansdown — TER ranges 0.20–0.45% depending on platform and underlying funds.
Who can open a LISA
- UK resident
- Age 18–39 at opening
- Can contribute until age 50
- 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
How the bonus works
- Contribute up to £4,000 per tax year
- Government adds 25% bonus the following month (so April 2026 contribution earns the bonus by mid-May)
- Bonus is paid into the LISA itself; it then grows alongside your contribution
If you start at age 22 and contribute £4,000/year through age 50, that's:
- £112,000 of your contributions
- £28,000 in government bonus
- Plus growth on both
At 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).
Qualifying uses
- 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 Funds withdrawn 12+ months after first contribution; sent directly to conveyancer.
- At age 60+ — withdraw for any reason, no penalty.
- Terminal illness — penalty waived.
- On death — penalty doesn't apply; passes to estate.
Non-qualifying withdrawal — the penalty math
Withdraw for any other reason and you pay 25% penalty on the total balance, not just the bonus.
If you contributed £4,000 and got £1,000 bonus (£5,000 total), and then need to withdraw early:
- 25% penalty: £1,250
- You receive: £3,750
- Net loss vs contribution: £250 (6.25% effective penalty)
So the penalty isn't just "give back the bonus." It's "give back the bonus plus a bit more." Plan accordingly.
LISA vs SIPP — which to fund
For first-time buyers under 40:
- LISA wins if you'll genuinely buy a home in the next 5–10 years and the property fits the £450k cap.
- SIPP wins for higher-rate taxpayers because 40% relief beats 25% bonus, even if you have to wait until 57 to access.
If 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.
Cash LISA vs Stocks & Shares LISA
- Cash LISA: 4.5–5.0% interest (May 2026), FSCS protected. Right for a near-term (1–4 year) home deposit.
- Stocks & Shares LISA: market-linked. Right for retirement-focused contributions or 7+ year horizon. Drawdown risk if used for short-term home deposit.
If your home purchase timeline is uncertain, split — half cash, half S&S.

What to actually do
- 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.
- If you're a higher-rate taxpayer — fund SIPP first up to your relief, then LISA, then ISA.
- If you're 40+ — LISA isn't open to new applicants. Use ISA + SIPP combinations instead.
FAQ
Can my partner and I both have a LISA for one purchase?
Yes — both partners qualifying as first-time buyers can use their LISAs toward one purchase. £8k/year of contributions × 25% = £2k/year of bonus.
Does the £450k cap count price or what we pay?
Purchase price. Includes any premium for fixtures/fittings if treated as part of the price.
What if my house price slightly exceeds £450k?
Don'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.
