How Much Deposit Do You Need to Buy a House in the UK in 2026?

If you're trying to buy your first home in 2026, the deposit is almost always the hard part. Mortgage rates have come off their peak, lenders are competing hard for low-deposit borrowers, and the government's deposit-support schemes are now permanent — but house prices keep grinding higher, and the cash you need up front has never been a bigger multiple of a typical salary.

This guide answers the question precisely: how much deposit you actually need, what that is in pounds where you're buying, and which schemes can close the gap. Every figure is cited to a primary source.

The short answer: 5% is the floor, more is cheaper

You can buy a UK home with a 5% deposit. That's the practical minimum, and it's deliberately supported by policy: the government's Mortgage Guarantee Scheme, made permanently available from July 2025, gives lenders a partial government guarantee so they can keep offering 91–95% loan-to-value mortgages to first-time buyers and home movers, on properties worth up to £600,000. (It doesn't cover buy-to-let, second homes or interest-only mortgages.)

But 5% gets you in the door; it doesn't get you the best rate. Lenders price mortgages in loan-to-value (LTV) bands, and the interest rate steps down as your deposit grows. The headline rate savings usually land at the 90%, 85%, 80% and 75% LTV thresholds. So the working rule for 2026 is:

• 5% deposit — minimum to buy; highest mortgage rates
• 10% deposit — meaningfully better rates than 95%
• 15% deposit — opens up much of the mainstream market
• 20–25% deposit — among the cheapest rates available

A bigger deposit does two things at once: it shrinks the amount you borrow and the rate you pay on it. That's why saving past a band boundary is often worth the wait.

What a deposit actually costs in pounds (2026)

The Office for National Statistics put the average UK house price at £270,000 in the 12 months to April 2026, up 3.8% on the year (ONS — Private rent and house prices, UK: June 2026). National averages diverge sharply, though, so the same percentage buys a very different deposit depending on where you are:

• England: £291,000 (up 3.9% in the 12 months to April 2026)
• Wales: £212,000 (up 3.5%)
• Scotland: £192,000 (up 2.8%)
• Northern Ireland: £198,000 in Quarter 1 2026 (up 7.4%)

All four figures come from the same ONS June 2026 bulletin. Apply the standard deposit percentages and the cash requirement looks like this:

Area (avg house price)	5% deposit	10% deposit	15% deposit	20% deposit
UK (£270,000)	£13,500	£27,000	£40,500	£54,000
England (£291,000)	£14,550	£29,100	£43,650	£58,200
Wales (£212,000)	£10,600	£21,200	£31,800	£42,400
Scotland (£192,000)	£9,600	£19,200	£28,800	£38,400
Northern Ireland (£198,000)	£9,900	£19,800	£29,700	£39,600

(Deposit figures are simple percentages of the cited ONS average prices.)

Two things jump out. First, the gap between a 5% and a 20% deposit on an average English home is over £40,000 — that's the real cost of waiting to save a bigger deposit, and the real value of the schemes that let you buy with 5%. Second, Scotland and Wales need roughly £15,000–£20,000 less for the same percentage than England, which is why "how much deposit" is really a "where are you buying" question.

Why the deposit is the hard part

Deposits feel impossible in 2026 because house prices have outrun wages for two decades. Nationwide's affordability research quantifies it bluntly: a 20% deposit is now equivalent to 110% of the pre-tax income of a typical full-time employee — a record high, up from 102% a year earlier (Nationwide — affordability special report). In other words, the deposit alone now costs more than a full year's gross salary.

The same report shows the first-time-buyer house-price-to-earnings ratio at 5.5, above the 2007 pre-crisis peak of 5.4 and well above the long-run average of 3.8. The regional spread is enormous — London sits at 9.0, while Scotland (3.4) and the North of England (3.5) remain close to their historical norms. And once you've bought, the running cost is steep too: a typical first-time-buyer mortgage payment now takes 31% of take-home pay, per the same Nationwide research.

This is the backdrop to every deposit decision in 2026: the cash hurdle is at a record high relative to incomes, which is exactly why the low-deposit routes below matter so much.

The 5% deposit routes are wide open in 2026

The good news is that low-deposit lending is healthier than it has been in years. Nationwide reports that high loan-to-value lending (deposits of 15% or less) reached its highest level for over a decade (Nationwide — house price review and outlook for 2026), and lender competition for low-deposit borrowers has pushed product choice at 90–95% LTV to its widest in years, according to Moneyfacts.

The two routes worth knowing:

1. The Mortgage Guarantee Scheme (a.k.a. "Freedom to Buy"). Permanent since July 2025, it backstops lenders offering 91–95% LTV mortgages on homes up to £600,000 to first-time buyers and movers (GOV.UK). You apply through a normal lender; the guarantee happens behind the scenes.
2. Standard 95% products. Many high-street lenders now offer 95% deals outside the scheme. With a 5% deposit you'll pay a higher rate than a 10% or 15% borrower, but the door is open.

The catch with 5% is rate, not access. Because your loan-to-value is high, you'll pay more interest — so if you can stretch to 10% you'll usually save meaningfully on the monthly payment.

Government help: the Lifetime ISA

The single most valuable deposit-building tool for most first-time buyers is the Lifetime ISA (LISA). The rules, straight from GOV.UK:

• You can pay in up to £4,000 a year, and the government adds a 25% bonus — up to £1,000 a year.
• You must be 18–39 to open one and make your first payment before you're 40; you can keep paying in (and earning the bonus) until you're 50.

The conditions for using it on a home are set out on the withdrawal rules page:

• The property must cost £450,000 or less.
• You must be buying with a mortgage, through a conveyancer or solicitor.
• You must buy at least 12 months after your first payment into the LISA.

The big watch-out: if you take the money out for any other reason (other than a first home, turning 60, or terminal illness), there's a 25% withdrawal charge — and because that charge applies to your contributions plus the bonus, you can end up with less than you originally paid in. The LISA is brilliant for a deposit; it's an expensive place to park money you might need for something else.

A worked LISA example: pay in the full £4,000 this tax year and the government tops it up to £5,000. Do that consistently and the bonus compounds into thousands of pounds of free deposit — the best risk-free return available to a first-time buyer, provided the eventual purchase stays under the £450,000 cap.

Don't forget the costs that sit alongside the deposit

The deposit isn't the only cash you need on completion. Budget separately for:

• Stamp duty. First-time buyers in England and Northern Ireland pay 0% up to £300,000 and 5% on the slice from £300,001 to £500,000, with the relief withdrawn entirely above £500,000. The rules differ in Scotland and Wales. We break down every band, with worked examples, in UK Stamp Duty in 2026: What Buyers Actually Pay, and you can get a figure instantly with the first-time-buyer stamp duty calculator.
• Legal and conveyancing fees — typically £1,000–£2,000.
• Survey — a few hundred pounds for a condition report, more for a full building survey.
• Mortgage product/arrangement fees — often £999–£1,499, sometimes addable to the loan.

A useful rule of thumb: have the deposit plus roughly 2–3% of the purchase price set aside for everything else.

So how big a deposit should you actually aim for?

There's no single right answer, but the trade-off is clear:

• If you can only reach 5%, the market is open — buy when the numbers work, and remortgage to a lower LTV band later as you pay down the loan and prices (hopefully) rise.
• If you're close to a band boundary (say a 12% deposit), it's usually worth pushing to 15% to drop from 90% to 85% LTV deals — the rate saving can outweigh a few more months of saving.
• If you have 20%+, you're into the cheapest part of the market; beyond about 25% the rate savings flatten, so extra deposit is better thought of as reducing your debt than chasing a better rate.

Whatever band you land in, the most expensive mistake is overpaying for the property itself. Every £10,000 you overpay is £10,000 of deposit and borrowing you didn't need to commit — and it doesn't come back when you sell.

How Offrly fits
