The deposit question is the first one almost every buyer asks — and the answer is more flexible than many people assume. Here's everything you need to know about deposit requirements in 2026.
Saving a deposit is widely considered the biggest hurdle on the road to homeownership. But understanding exactly how much you need — and what that figure gets you — can transform the way you plan your purchase. The good news is that the UK mortgage market in 2026 has more options than ever, from 5% deposits right through to some lenders reintroducing 0% deals.
For most residential buyers, the minimum deposit accepted by UK mortgage lenders is 5% of the property's value. On a £300,000 home, that means £15,000 upfront. These 95% loan-to-value (LTV) mortgages are widely available and have become more accessible in 2026, with lenders competing aggressively for first-time buyer business.
Bear in mind that 5% deposit mortgages will carry higher interest rates than products at lower LTVs, so your monthly repayments will be larger. They are, however, a legitimate and well-used route onto the property ladder.
Example: Buying a £250,000 property with a 5% deposit (£12,500) means borrowing £237,500 at 95% LTV. Stepping up to a 10% deposit (£25,000) reduces your borrowing and typically unlocks a meaningfully lower rate — often saving hundreds of pounds per year.
The more deposit you can put down, the better the deal you'll generally access. Lenders price their mortgages around key LTV bands — 95%, 90%, 85%, 75%, and 60% being the most important. Each time you cross a threshold, you unlock a new tier of rates.
The most common mortgage type in the UK has an LTV of 75% or below, meaning many buyers are putting down at least 25%. The coveted 60% LTV band — where you're borrowing 60% and putting down 40% — represents the very best rates lenders offer. While most buyers won't have that level of equity at first purchase, it's worth knowing as a longer-term remortgage target.
Deposit Size vs. LTV — Quick Reference
- 5% deposit = 95% LTV — on a £250,000 property: £12,500
- 10% deposit = 90% LTV — on a £250,000 property: £25,000
- 15% deposit = 85% LTV — on a £250,000 property: £37,500
- 25% deposit = 75% LTV — on a £250,000 property: £62,500
- 40% deposit = 60% LTV — on a £250,000 property: £100,000
According to Halifax data, the average deposit paid by a first-time buyer in 2024 was £61,090 — representing roughly 20% of the average purchase price of £311,034. In London, average deposits were significantly higher, reaching £124,688. These figures reflect both the aspiration to access better rates and the reality of rising property prices across the country.
A small number of 100% LTV (0% deposit) mortgages have begun to reappear in 2026. In February 2026, Melton Building Society launched a 0% deposit mortgage, available exclusively through mortgage brokers and subject to strict manual underwriting. Guarantor mortgages — where a close family member uses their property or savings as security — also allow buyers to borrow without a cash deposit in some cases. These products carry higher risks and are assessed carefully by lenders, but they do exist for the right borrower.
If you're purchasing an investment property rather than a home to live in, expect to need at least 25% as a deposit — and ideally 30–40% to access competitive buy-to-let rates. Lenders consider rental properties higher-risk investments, which is reflected in stricter deposit requirements and higher interest rates across the board.
The Lifetime ISA (LISA) remains one of the most effective savings tools available to first-time buyers: the government adds £1 for every £4 you save, up to £4,000 per year — a bonus of up to £1,000 annually. Gifted deposits from family members are also accepted by many lenders, subject to anti-money laundering checks and a clear paper trail. Your broker can guide you on structuring a gifted deposit correctly to satisfy lender requirements.
