How to Save for a House Deposit in 2026

Quick answer

Saving a house deposit in 2026 comes down to three moves: pick a realistic target, use the Lifetime ISA to get a free 25% top-up while you can, and keep the money somewhere safe and growing rather than idle in a current account. Help to Buy is gone, so the LISA bonus is now the single biggest free boost available to a first-time buyer — and on the full £4,000 a year it is worth £1,000 of government money you would otherwise leave on the table.

This guide gives you a concrete plan: how much to aim for, how the LISA works in practice, where to keep the cash, and how to make the deposit grow faster without taking risks you cannot afford.

How big a deposit do you actually need?

Lenders express your deposit as loan-to-value (LTV). A 10% deposit means a 90% LTV mortgage; a 5% deposit means 95%. The headline rule is simple: the bigger your deposit, the cheaper your mortgage, because lenders price in bands and step the rate down as your LTV falls.

Here is roughly what a deposit looks like on three common price points:

A 5% deposit gets you on the ladder, but a 10% deposit usually unlocks a noticeably better rate, and pushing towards 15% or 25% better still. If you can stretch your timeline by a few months to cross from 5% to 10%, the saving over the life of the mortgage often dwarfs the extra you put in.

Crucially, the deposit is not the whole bill. You will also need cash for conveyancing and legal fees, a survey, mortgage arrangement fees and moving costs — easily a few thousand pounds. First-time buyers in England and Northern Ireland benefit from stamp duty relief up to a threshold, but budget for it on higher-priced homes.

The Lifetime ISA: your biggest free boost

Now that Help to Buy has closed, the Lifetime ISA (LISA) is the headline government product for first-time buyers. The mechanics are generous and worth understanding precisely:

• You can pay in up to £4,000 a year (this counts within your overall £20,000 ISA allowance).
• The government adds a 25% bonus on what you pay in — so the full £4,000 attracts £1,000 of free money.
• The bonus is paid monthly, and it then grows alongside your own contributions, tax-free.
• You can open one between ages 18 and 39 and keep paying in (and earning the bonus) until you turn 50.

There are conditions you must respect:

• The property must cost £450,000 or less.
• It must be your first home — you must never have owned property anywhere.
• The account must have been open at least 12 months before you withdraw for the purchase. This is the rule that catches people out: open one early, even with £1, to start the clock.

The sting is the withdrawal penalty. If you take money out for anything other than a qualifying first-home purchase (or reaching age 60), you pay a 25% charge — which, because of how the percentages work, claws back slightly more than the bonus and dips into your own contributions. So only put money into a LISA that you are confident you will use for a deposit.

Two people buying together can each hold a LISA, doubling the bonus to £2,000 a year between them. Model how the bonus compounds over your saving period with the

Cash LISA or stocks-and-shares LISA?

LISAs come in two flavours. A cash LISA behaves like a savings account: your balance cannot fall, and you earn interest plus the bonus. A stocks-and-shares LISA invests your money, which can grow more over many years but can also fall in value.

The rule of thumb is timeline-driven. If you plan to buy within the next one to three years, choose a cash LISA — you cannot risk a market dip wiping out part of your deposit right before completion. If your purchase is genuinely five or more years away, a stocks-and-shares LISA may grow more, but you must be comfortable with the ups and downs. For most active deposit-savers, who want to buy soon, cash is the sensible default.

Where to keep the rest of your deposit

Money beyond your £4,000 LISA contribution needs a home too. The same timeline logic applies: deposit cash you will need within a year or two belongs in safe, accessible places, not the stock market.

A sensible structure for many savers:

1. Cash LISA — fill the £4,000 to capture the full £1,000 bonus first; nothing else beats a guaranteed 25% top-up.
2. Cash ISA or easy-access savings — for the rest of your annual saving, keeping interest tax-free where possible.
3. Fixed-rate savings — if you are certain you will not need the money for, say, a year, a fixed bond can pay a little more.

Always use your tax-free ISA allowance before ordinary taxable savings, so the interest is not eroded by tax. See how different rates and regular top-ups build up over your saving window with the

Make a realistic plan with real numbers

The difference between "I'd like to buy a house one day" and actually doing it is a number and a date. Work backwards:

1. Set a target deposit. Pick a price you could realistically buy in your area, choose an LTV (aim for 10% if you can), and that is your deposit goal — then add a few thousand for fees.
2. Set a date. When do you want to buy?
3. Divide. Target deposit minus what you already have, divided by the months remaining, gives your required monthly saving — before the LISA bonus, which then accelerates it.
4. Stress-test it. Is that monthly figure sustainable alongside your rent and bills? If not, extend the date or lower the target.

Because the LISA bonus and savings interest both compound, your money grows faster than a simple division suggests. See exactly how much regular saving plus the bonus and interest will accumulate by your target date using the

Ways to save faster

• Automate it. Set a standing order into your LISA and savings on payday so the money is gone before you can spend it.
• Fill the LISA first, every year. A guaranteed 25% bonus beats any interest rate; missing a year's allowance means missing up to £1,000 of free money you cannot reclaim later.
• Cut the big three, not the small ones. Rent, transport and food move the needle far more than skipping coffees. Could a temporary house-share or a cheaper commute free up hundreds a month?
• Funnel windfalls. Bonuses, tax refunds and gifts go straight to the deposit pot.
• Check for help. Some employers, and some shared-ownership or first-homes schemes, can reduce the deposit you need. Explore what is available locally.

What about the schemes that replaced Help to Buy?

With the Help to Buy equity loan gone, it is worth knowing what does still exist, because the right scheme can shrink the deposit you need or the price you have to fund.

Shared ownership lets you buy a share of a property (often between 25% and 75%) and pay rent on the rest, with the option to "staircase" — buying more of the home over time. Because you only need a deposit on the share you buy, the cash required upfront is much smaller. The trade-offs are the rent on the unowned portion, service charges, and restrictions on selling, but for buyers priced out of the open market it can be a genuine route in.

First Homes schemes, where available, offer eligible first-time buyers and local people a discount on the market price of certain new-build homes, with the discount passed on to future buyers too. Availability is local and limited, so check what is offered in your area.

Lender-specific low-deposit and guarantor options also exist, including mortgages aimed at buyers with only a 5% deposit and arrangements where a family member's savings or property help secure the loan. These do not replace saving a deposit, but they can lower the bar.

None of these is as simple as the old equity loan, and each has conditions, so research carefully. But the headline point stands: the absence of Help to Buy does not mean there is no help — it means the Lifetime ISA is your main savings booster, with shared ownership and local schemes as routes to needing less deposit in the first place.

Protecting your deposit while you save

Saving the money is only half the job; keeping it safe and accessible is the other half. A few principles protect a deposit fund:

• FSCS protection. Cash held with an authorised UK bank or building society is protected up to the Financial Services Compensation Scheme limit per institution. If your deposit is large, spreading it across providers keeps it all protected.
• Avoid lock-ups you cannot afford. Fixed-rate bonds pay more but tie your money up. Do not lock away cash you might need for the purchase before the term ends.
• Mind the LISA withdrawal rules. Remember the 12-month account-age rule and the 25% penalty for non-qualifying withdrawals. Only put money you are confident you will use for the home into a LISA.
• Keep an emergency buffer separate. Do not pour every spare pound into the deposit and leave yourself with nothing for a car repair or a job gap. A small accessible emergency fund stops you raiding the deposit — or worse, the LISA with its penalty.

How long will it realistically take?

The honest answer depends on three levers: how much you can save each month, the return you earn, and how big a deposit you are targeting. The encouraging part is that the LISA bonus and compound interest both work in your favour, so the timeline is usually shorter than a simple "target divided by monthly saving" suggests.

A useful exercise is to model two or three scenarios — a comfortable monthly amount, a stretch amount, and your absolute maximum — and see how each changes your buy-by date. Often the difference between saving an extra £100 a month is a year or more off the timeline, which can be powerful motivation. Equally, lowering your target from a 10% to a more modest deposit, or looking at a slightly cheaper area, can bring the date forward dramatically. Run these scenarios through the

and the to find the combination that is both achievable and fast enough to keep you motivated.

A word on inflation and house prices: while you save, property prices may move, so a fixed cash target can become a moving goal. This is an argument for not over-extending your timeline — the longer you save, the more the target may drift. Saving aggressively early, capturing the LISA bonus each year, and buying when you have a solid 10% rather than holding out indefinitely for 20% is, for many people, the pragmatic path onto the ladder.

A worked example

Suppose two first-time buyers want a £250,000 home with a 10% deposit (£25,000) plus £4,000 for fees — £29,000 total — in three years. They have £5,000 already, leaving £24,000 to find over 36 months, or £667 a month between them.

If they each pay £333 a month into a cash LISA, they together hit roughly £4,000 each in year one and earn the full bonus, with the government adding up to £2,000 a year between them. Once you fold in the bonus and interest, their own contributions need to be lower than the raw £667 to reach the target — the free money does part of the work. Plug your own figures into the

and the to find the monthly figure that gets you there on time.

The bottom line

Saving a deposit in 2026 is a solved problem if you act deliberately: set a real target and date, open a Lifetime ISA early to start the 12-month clock and capture the 25% bonus, keep near-term money in cash, and automate your saving so it happens without willpower. Help to Buy may be gone, but the LISA bonus is free money for first-time buyers — and the sooner you start, the more of it you collect.
