# No-Deposit Mortgages Return in the UK: The Appeal and the Risk

A handful of UK lenders are again offering 100% mortgages, home loans that require no deposit, aimed at first-time buyers priced out by years of saving. They can get renters onto the housing ladder sooner, but they also carry a real danger the market spent a decade avoiding: negative equity. Here is how they work and what to weigh.

For most of the past decade, buying a first home in Britain has meant one daunting prerequisite: a deposit, often tens of thousands of pounds saved up front. Now a small but growing number of lenders are offering a way around it. Banks and building societies have brought back [100% mortgages, loans that cover the entire purchase price with no deposit, aimed at first-time buyers, according to the Guardian](https://www.theguardian.com/money/2026/jul/17/first-time-buyers-mortgage-loans-banks-building-societies). Their return is notable, because these products all but vanished after the last housing crash.

## What a 100% mortgage is

A normal mortgage requires a deposit, commonly 5% to 10% of the price, with the lender providing the rest. On a £250,000 home, a 10% deposit is £25,000 to find before you even start. A 100% mortgage removes that hurdle: the lender advances the full price, so you can buy without a deposit at all.

To manage the extra risk, lenders wrap conditions around these deals. Several are aimed at renters who can prove a solid track record of paying rent on time; others require a family member to act as a guarantor, effectively pledging their own savings or property as backup if the borrower cannot pay. The interest rates on no-deposit loans are typically higher than on mortgages where the buyer puts money down, and the size of the loan is usually capped. The specific rates and terms vary by lender and change frequently, so any figure quoted today may not last.

## The appeal

The case for them is real. Rents in Britain are high, and a would-be buyer can spend years paying a landlord while trying, often failing, to save a deposit as prices rise. A 100% mortgage short-circuits that: instead of building someone else's wealth through rent, the buyer starts building their own equity immediately. For people with a stable income but no lump sum, and no wealthy relative to tap, it can be the only realistic route onto the property ladder.

## The risk that sank them last time

The danger is captured by one phrase: **negative equity**. If you borrow the entire value of a home and prices then fall, you can quickly owe the bank more than the property is worth. [Negative equity means you would still owe money even after selling the house, and it can leave you a "mortgage prisoner," unable to move or switch to a cheaper loan because no lender will refinance a mortgage worth more than the home, as MoneyHelper explains](https://www.moneyhelper.org.uk/en/homes/buying-a-home/negative-equity-what-it-means-and-what-you-can-do-about-it). A buyer who put down a deposit has a cushion against a price dip; a no-deposit buyer has none.

This is not hypothetical. In the financial crisis that began in 2007, UK house prices fell sharply, and many people who had bought with little or no deposit, some with mortgages for more than 100% of a home's value, were left trapped owing more than their houses were worth. That experience is exactly why these loans disappeared, and why their comeback deserves a clear-eyed look.

## How to think about it

None of this is advice to take one or avoid one; it is a matter of understanding the trade-off. A 100% mortgage is, in effect, a bet that house prices will hold or rise and that you can comfortably make every payment, with no margin for error if either assumption fails. It suits someone with secure income who plans to stay in the home for many years, long enough to ride out a downturn, far less someone who might need to sell soon or whose finances are tight. The product genuinely helps buyers who have been shut out of the market; it also removes the safety buffer a deposit provides. Anyone considering one should weigh both sides, and read the specific terms carefully. Boursel does not give borrowing or investment advice.
