Lifetime ISA for First-Time Buyers: The Free £1,000 Government Bonus Explained

The Lifetime ISA (LISA) is one of the most valuable savings products available to UK first-time buyers. The government adds a 25% bonus to every pound you save — up to £4,000 per year. That means up to £1,000 in free money annually, just for saving toward your first home. If you're eligible, not using a LISA is leaving money on the table.

You must be between 18 and 39 to open a LISA. You can save up to £4,000 per year and receive a 25% bonus on contributions. The bonus is paid monthly on contributions made. To use the LISA for a property purchase, the property must cost £450,000 or less, you must have owned it for at least 12 months before buying, and you must be a first-time buyer.

Save £4,000/year × 5 years = £20,000 of your own contributions. Government bonus: £5,000. Total saved in 5 years: £25,000 — before any investment growth or interest. Add 5% annual growth on a Stocks and Shares LISA and that £25,000 could be £30,000–£32,000 in real terms. That's a meaningfully larger deposit made possible entirely by starting a LISA at 25 rather than 30.

A Cash LISA offers a fixed interest rate (currently 3–4% from providers like Moneybox). A Stocks and Shares LISA invests in funds with higher long-term growth potential but short-term volatility. If your timeline to buying is less than 3 years, a Cash LISA is safer — market dips close to your purchase date could reduce your pot. If you have 5+ years, a Stocks and Shares LISA's growth potential typically outweighs the volatility risk.

If you withdraw from a LISA for anything other than a first home purchase or retirement (age 60+), you pay a 25% withdrawal penalty. This claws back the government bonus plus a small portion of your own contributions. Effectively: only open a LISA if you're genuinely saving for a first home or retirement. It's not an emergency fund.

The LISA's annual allowance (£4,000) also resets on April 5. If you open a LISA before April 5 and deposit even £1, you qualify for this tax year's bonus on that £1. Many first-time buyers open their LISA the final week of the tax year specifically to lock in eligibility and start receiving monthly bonus payments from April 6 onward.
