Opening a Lifetime ISA is one of those tasks that sounds more complicated than it is. Most people can do it in under fifteen minutes on their phone. The harder part is knowing which provider to use and making sure you understand the rules before you commit — because once money is in a LISA, the restrictions on getting it out are real.
This is the practical walkthrough: where to open one, what to expect, and the things worth knowing before you start. Not financial advice — but a clear, honest guide to the process.
The LISA is not a standard savings account. Before opening one, three things are worth being clear on.
First, the age limit. You must be between 18 and 39 to open a Lifetime ISA. Once open, you can contribute until age 50. But if you have not opened one before your 40th birthday, the option closes permanently. If you are approaching 40 and think a LISA might be useful, open one now — even with £1 — and decide later how much to put in.
Second, the withdrawal restriction. You can only withdraw without penalty in two situations: to buy your first home (property must be £450,000 or under, purchased with a mortgage, after the account has been open for 12 months), or for retirement from age 60. Withdraw for any other reason and a 25% penalty applies to the full amount including the bonus — which can leave you with less than you originally contributed.
Third, the 12-month rule. You cannot use your LISA toward a property purchase until 12 months after your first contribution. The clock starts on the date of that first payment, not when you open the account. Open and contribute as early as possible.
There are four main types of LISA provider and the right one depends on what you are saving for and how hands-on you want to be.
Moneybox is the most popular app-based option and the one I would suggest for most first-time buyers who want a simple, guided experience. The app is well designed, the onboarding is clear, and the ready-made investment portfolios remove the fund selection decision. Fees are 0.45% per year plus underlying fund costs.
AJ Bell is my preference for people who want a lower-cost option with broader investment choice. The platform fee of 0.25% makes it cheaper than Moneybox at larger pot sizes, and you have access to a wide range of funds rather than just a curated selection. Better suited to people comfortable making their own investment decisions.
Hargreaves Lansdown suits people who already use HL for other investments and want everything in one place. The fund range is the widest available. Fees are slightly higher than AJ Bell but the platform quality is excellent.
Moneybox Cash LISA is worth considering if you are buying within 1-2 years and cannot afford for the value to fall before you need it. A Cash LISA pays interest rather than investing in funds — no investment risk, but lower long-term growth potential.
Opening a LISA is straightforward with any of the major providers. The process is broadly the same across all of them:
The government bonus is added monthly — typically within 6-8 weeks of your contribution. You will see it appear in your account as a separate entry.
The maximum is £4,000 per year, and the government adds 25% on top (up to £1,000). Contributing the full £4,000 every year maximises the bonus. If that is not affordable, any amount generates the bonus proportionally — £2,000 gets you £500 in government contributions.
Monthly contributions of £333 per month hit the annual maximum. Many people find it easier to set up a standing order for a round number — £300 per month, for example — and make a top-up contribution near the end of the tax year if they have capacity.
The LISA allowance does not carry over between tax years. Unused allowance from 2025/26 cannot be added to 2026/27's £4,000 limit. Each tax year is independent.
