Lifetime ISA vs Pension for a House Deposit UK 2026: Which Builds It Faster?
Both a Lifetime ISA and a pension get a government top-up on what you pay in, but only one of them can fund a first-home deposit before you turn 55. This guide compares the LISA 25% bonus against pension tax relief for would-be first-time buyers, with 2026/27 figures, a worked example, and clear guidance on which to prioritise for a deposit.
TL;DR -- 30-Second Summary
- • Lifetime ISA: GBP 4,000 a year, 25% bonus (up to GBP 1,000), usable for a first home up to GBP 450,000
- • Pension: 20% basic-rate relief (40% for higher-rate), but locked until age 55 (57 from 2028)
- • For a deposit: the LISA wins because pension money cannot be withdrawn for a house
- • For retirement: a pension usually wins, especially for higher-rate taxpayers
- • Best of both: LISA for the deposit, workplace pension for retirement and employer match

How the LISA Bonus Builds a Deposit
The Lifetime ISA is the only one of the two products designed to fund a first home. Pay in the GBP 4,000 maximum and the government adds GBP 1,000, giving you GBP 5,000 of deposit money for every GBP 4,000 you save. The bonus is paid monthly on contributions, so it also starts earning interest or investment returns inside the account.
Because the bonus is flat 25%, it is the same whether you are a basic-rate or higher-rate taxpayer. That makes the LISA especially attractive for basic-rate taxpayers, for whom the uplift matches what they would get from pension relief, but with the crucial advantage that the money can be used to buy a home costing up to GBP 450,000.
Worked Example: Four Years of Saving
Suppose a 28-year-old basic-rate taxpayer saves the full GBP 4,000 into a Lifetime ISA for four tax years to build a deposit, ignoring investment growth to keep the comparison clear.
| Item | Lifetime ISA | Pension (for comparison) |
|---|---|---|
| Own contributions (4 x GBP 4,000) | GBP 16,000 | GBP 16,000 |
| Government top-up | GBP 4,000 bonus (25%) | GBP 4,000 relief (20% grossed up) |
| Total pot | GBP 20,000 | GBP 20,000 |
| Available for a house deposit now? | Yes -- full GBP 20,000 | No -- locked until age 55 |
The headline pots are identical at GBP 20,000 for a basic-rate taxpayer, because 25% of the net amount equals 20% relief grossed up. But only the LISA can release that GBP 20,000 for a deposit. The pension version stays locked for decades, which is why the LISA is the right tool for the deposit even though the up-front maths matches.
When the Lifetime ISA Wins
For anyone whose goal is a first-home deposit within the next several years, the LISA wins outright: it offers the same up-front bonus as basic-rate pension relief but lets you actually spend the money on a home up to GBP 450,000. Basic-rate taxpayers in particular give up nothing in top-up terms by choosing the LISA over a pension for this purpose.
The LISA is also tax-free on withdrawal, so the GBP 20,000 in the example above is fully available with no further tax, unlike a pension where only 25% comes out tax-free and the rest is taxed as income in retirement.
When the Pension Wins
For long-term retirement saving rather than a deposit, the pension usually wins. A higher-rate taxpayer gets 40% relief, well above the 25% LISA bonus, and a workplace pension often comes with employer contributions that a LISA cannot match. The GBP 60,000 annual allowance also dwarfs the GBP 4,000 LISA limit, so larger sums can be sheltered.
The sensible approach for many first-time buyers is to use both: keep contributing to the workplace pension to capture the employer match and relief, and run a Lifetime ISA alongside it dedicated to the deposit. That way the deposit goal does not derail retirement saving.
