Should I Open a LISA Before 2028? The Grandfathering Window Closing Soon
There is a deadline approaching that very few 18-to-39-year-olds in the UK are paying attention to. In April 2028, the government is scrapping the Lifetime ISA and replacing it with a new First-Time Buyer ISA. The rules will be different. The bonuses will be different. And the key detail almost no one is talking about: if you open a Lifetime ISA before April 2028, you are grandfathered in — permanently. Even if you put in just £1.
That means the decision is not really about whether you want a LISA right now. It is about whether you want the option of having one on the current, more generous terms — before the window closes forever.
This is a classic do-it-now-or-lose-the-option moment. And most people in the eligible age bracket will not act, because the deadline feels distant, the form-filling feels like effort, and there is always something more urgent to deal with today. That is exactly how HMRC's changes work best: they rely on inertia.

What Is a Lifetime ISA and Why Does It Exist
The Lifetime ISA (LISA) launched in April 2017 as a government-backed incentive to help younger people either buy their first home or save for retirement. It sits alongside other ISA types — Cash ISA, Stocks & Shares ISA, Innovative Finance ISA — and has its own rules and its own very specific government bonus.
Here is how it works:
- Eligibility: You must be aged 18 to 39 to open one. Once open, you can keep contributing until you are 50.
- Annual limit: Up to £4,000 per tax year.
- Government bonus: 25% on everything you contribute — up to £1,000 free money per year. Pay in £4,000, the government adds £1,000. Over 10 years, that is up to £10,000 in free bonuses alone.
- Two qualifying uses: Buying your first home (property priced up to £450,000) or accessing the money from age 60 as a retirement fund.
- The catch: Withdraw for any other reason and you pay a 25% government penalty — which on a boosted balance actually works out as a 6.25% loss on your original contributions. Not a tax, but close to one.
For first-time buyers specifically, the LISA is genuinely one of the best free money offers available in the UK. No equivalent product gives you an instant 25% return on contributions — not a pension (higher earners excepted), not an ISA, not anything else. The bonus is paid monthly. It compounds. It builds.
The Stocks & Shares LISA is particularly underused. Most people open a Cash LISA and leave it in savings. But you can invest your LISA contributions in index funds, ISA-style — growing the bonus-enhanced contributions in global equities over a 10-15 year horizon. The compounding potential is significant.
What Changes in April 2028: LISA vs First-Time Buyer ISA
The government announced in the Autumn 2025 Budget that the Lifetime ISA will be replaced from April 2028 by a new product: the First-Time Buyer ISA (FTBI). The full details are still being consulted on, but the key differences expected are:
| Feature | Lifetime ISA (current) | First-Time Buyer ISA (from 2028) |
|---|---|---|
| Age to open | 18–39 | 18–39 (expected) |
| Annual contribution limit | £4,000 | £4,000 (expected) |
| Government bonus | 25% (up to £1,000/year) | 25% — but capped at lower property price |
| Property price cap | £450,000 | £350,000 (proposed) |
| Retirement use | Yes (from age 60) | No — first-time buyer only |
| Withdrawal penalty | 25% (on total including bonus) | Being redesigned — likely lighter |
The property price cap change is significant. In London and the South East, the median first-time buyer property price is well above £350,000. A FTBI capped at £350,000 is largely useless for buyers in the most expensive markets — exactly the buyers who most need the bonus subsidy. The LISA's £450,000 cap, imperfect as it is, covers a far wider range of realistic first-time purchases.
The loss of the retirement option is the other major downside. The current LISA is a dual-purpose product — it helps you buy a house AND builds a retirement pot if life takes a different direction. The FTBI removes that flexibility entirely. If your house purchase falls through, gets delayed, or you decide not to buy — the FTBI is essentially trapped money with no retirement exit.
The Grandfathering Clause: Why Opening Now Matters
Here is the mechanism that makes this genuinely urgent:
If you open a Lifetime ISA before April 2028, you keep it under current LISA rules — permanently.
The FTBI replaces the LISA for new applicants. Existing LISA holders are not forced to convert. You keep the £450,000 property price cap. You keep the retirement withdrawal option from age 60. You keep the ability to contribute until 50. You keep the 25% bonus on all contributions up to £4,000 per year.
The practical implication is straightforward: if you are between 18 and 39 right now, opening a LISA before April 2028 with as little as £1 locks in access to the better product on the better terms. You are not committing to anything. You are not locking away significant money. You are simply preserving your option.
Opening a LISA today, putting in £1, and leaving it empty costs you nothing. Failing to open one and discovering you want one in 2029 — after you've turned 40, or after the window has closed — costs you access to up to £10,000 in government bonuses over a decade. That asymmetry is massive.
The question is not whether you are definitely buying a house within five years. The question is: are there circumstances in which having a LISA would benefit you? If there are — and for most people in their 20s and 30s the honest answer is yes — then the right move is to open one before April 2028 and decide what to do with it later.
Who Should Open a LISA Before the Deadline
Not everyone. But the bar is lower than most people think.
Open one now if:
- You are between 18 and 39 and have any realistic chance of buying a first home in the next 15 years
- You are in your late 30s and approaching the eligibility cutoff — this is your last window
- You want a flexible retirement savings vehicle that sits alongside your pension
- You can put away even £25/month without straining your finances — the 25% bonus turns that into £31.25 each month
- You are buying in London or the South East where the £450,000 cap matters and the £350,000 FTBI cap would exclude your realistic purchase
Think carefully before opening one if:
- You have high-interest debt — clearing 20% APR credit cards beats a 25% one-off bonus once you factor in timing
- You are very close to 40 but have minimal time to build contributions — crunch the numbers to make sure the bonus outweighs the reduced flexibility
- You need the money in fewer than 5 years for something other than a house — the 25% withdrawal penalty is punitive for near-term needs
Do not open one if:
- You already own a property — the first-time buyer rule is strict
- You are 40 or older — not eligible to open one
For the majority of people in their 20s and early 30s with any intention of home ownership in the UK, the answer is: yes, open one now, even with minimal contributions, to preserve optionality before 2028.
Best LISA Providers 2026
Not all LISA providers are equal. There are three meaningful differences to compare: whether they offer a Cash LISA, Stocks & Shares LISA, or both; the quality of the investment options if you want the S&S version; and the platform's broader ISA and investment offering if you want to consolidate accounts.
| Provider | LISA Type | Best For | Min to Open | Apply |
|---|---|---|---|---|
| Moneybox | Cash + Stocks & Shares | App-first, small regular savers | £1 | Open Moneybox LISA |
| Hargreaves Lansdown | Stocks & Shares | Wide fund choice, established platform | £1 | Open HL LISA |
| AJ Bell | Stocks & Shares | Lower fees, integrated account | £500 lump or £25/mo | Open AJ Bell LISA |
| Nutmeg | Stocks & Shares | Managed portfolio, hands-off | £100 | Direct application |
Moneybox
Moneybox offers both Cash LISA (for those who want zero market risk) and Stocks & Shares LISA (for long-term investing). Their app is the best in class for younger savers — simple weekly top-ups, clear bonus tracking, round-up savings integration. The Cash LISA rate is competitive in the current environment. If you want to open a LISA for £1 today just to lock in the product before 2028, Moneybox is the easiest path. The onboarding takes under 10 minutes.
Hargreaves Lansdown
Hargreaves Lansdown is the UK's largest investment platform, and their LISA offering benefits from that depth. You can access thousands of funds, investment trusts, and ETFs within the LISA wrapper — including Vanguard's index fund range, which many LISA investors use as a default strategy. The platform UX is robust and the customer service is well-reviewed. If you already have a Stocks & Shares ISA or pension with HL, adding a LISA to the same account is a clean experience. Annual platform charge is 0.45% on the first £250,000 (capped).
AJ Bell
AJ Bell is strong for cost-conscious investors. Platform charges are 0.25% (capped at £42/year for a LISA), meaningfully cheaper than HL for smaller pots. They offer a comparable fund range including index ETFs, and the integrated account structure — holding LISA, ISA, and SIPP in one place — is useful for people thinking about coordinating their long-term financial planning. The minimum is higher than Moneybox, so not ideal for the purely-opening-for-£1 approach, but excellent for regular monthly investors.
How to Open a LISA: Step by Step
The process is genuinely straightforward. The whole thing takes 15–20 minutes.
- Confirm eligibility. You must be 18–39 and a UK resident. You must not have previously used a LISA to buy a property.
- Choose your provider. If you want Cash LISA: Moneybox. If you want Stocks & Shares LISA: Moneybox, HL, or AJ Bell depending on your fee sensitivity and existing accounts.
- Complete the application. National Insurance number, UK address, bank details. For S&S LISAs you'll answer a few investor risk questions. No credit checks involved.
- Make your first contribution. Even £1 counts. This formally opens the account. The government bonus is paid monthly once HMRC processes the contribution — typically within 6–8 weeks of your first deposit.
- Set up a regular contribution if you want to. Most providers allow standing orders from £25/month. You don't have to — but if you can, start small and increase over time. The bonus compounds.
That is it. The LISA is open. You are grandfathered into the pre-2028 rules regardless of whether you ever make another contribution. The pressure is off. Decisions about property timelines and contribution levels can wait. The single irreversible decision — opening before April 2028 — is done.
The Psychology of Doing Nothing
Most people who are eligible to open a LISA have heard of it. Most of them have not opened one. This is not a coincidence — it is the status quo bias operating exactly as designed.
Inaction feels like a non-choice. It requires no decision, no forms, no effort, no account logins. The cost of inaction is invisible today — it shows up in 2029 when you realise the FTBI's £350,000 property cap excludes the house you want to buy, or in your early 60s when you realise you could have had a second retirement pot growing tax-free for 25 years.
The FOMO here is rational, not manufactured. The deadline is real. The grandfathering clause is real. The financial difference between opening before April 2028 and not doing so is quantifiable: up to £10,000 in government bonuses over a decade, on top of compounded investment returns on a boosted pot.
Opening for £1 today costs you nothing. It creates asymmetric optionality — significant upside if you use it, zero downside if you never contribute again. That is an extremely rare proposition in personal finance.
The Bottom Line
The Lifetime ISA is being replaced by a less generous product. Anyone aged 18–39 who opens one before April 2028 keeps the better product on the better terms — the £450,000 property cap, the retirement withdrawal option, the full 25% bonus. That window is closing, and once it does, it does not reopen.
If you are in the eligible age bracket, the question is not whether you are definitely buying a house. It is whether you want to preserve the option. For most people under 39, the honest answer is yes.
The move: open a Moneybox LISA today for £1. It takes 15 minutes. The account exists, you are grandfathered in, and you can decide what to do with it when you have more information about your own plans. The only version of this story where you lose is the one where you wait until 2028 and find the window has closed.
