Over the last few years, UK mortgage lenders have been pretty cautious when it comes to high loan-to-value (LTV) deals. Traditionally, most have insisted on at least a 10% deposit before they’ll consider an application. But things are slowly shifting. Lending above 90% LTV has picked up and is now at its strongest point in quite some time, helped along by lenders easing some of their affordability rules.
A few lenders have now even brought back 100% mortgages – meaning no deposit at all. These can be a lifeline for first-time buyers who are struggling to save a lump sum, though they do usually come with higher costs and more in-depth affordability checks.
Overall, it’s a reassuring shift for buyers who don’t have a big pot of savings. High-LTVs and no-deposit mortgages are definitely reappearing, but they’re not quite back to being everyday options – at least not for now.

Understanding 100% Mortgages and High LTVs
High-LTV mortgages let you borrow nearly everything. A 100% mortgage lets you borrow literally everything – i.e. “no deposit” required. And the reason these products are back on the table is blunt: the UK property market has boxed buyers into a corner. Prices are rising faster than most people can save, living costs are eating away any chance of building a deposit, and the traditional “save 10% first” advice has become increasingly unrealistic. For a huge number of first time buyers, high-LTV and zero-deposit mortgages aren’t just helpful – they’re the only lifeline left.
Lenders know this too. That’s why, backed by schemes like the Mortgage Guarantee Scheme and a renewed appetite for risk, they’re creeping back into the high-LTV space. But make no mistake: these mortgages come with a price. Higher rates. Stricter affordability checks. Smaller safety nets. If you go down this route, you’re trading a quicker path into a home for a tighter financial squeeze. It can get you through the door – but only if you’re ready for the pressure that comes with it.
Why Are These Mortgages Making a Comeback?
Several factors are driving this revival:
- House prices are still high in many parts of the UK. This makes it hard for people who don’t have a lot of money saved up to make big deposits. High-LTV mortgages lower the amount of money you need to put down up front.
- Government-backed mortgage guarantee plans make it easier for lenders to offer high-LTV products. They lower the risk for lenders. These plans are mostly for first-time buyers who can only put down a small amount of money.
- A few lenders are adding more high-LTV products to their lines. Some give you cash-back or make the rules more flexible as incentives. This helps bring in buyers who can’t save up a full deposit.
- More and more people want to build their own homes or have them built for them. Specialist lenders for self-build projects offer staged funding. These choices can work with deposits that aren’t too big at first, but they have different rules for lending.
What the Numbers Say: High-LTV Mortgage Activity in 2025
The rise of high-LTV and near-100 mortgages in the UK is supported by real market data from 2025.
In Q3 2025, gross mortgage advances reached £80.4 billion, a 36.9 % increase from the prior quarter, one of the strongest growth periods in recent years.
- High-LTV lending is clearly on the rise: mortgages with LTV over 90 % made up 7.4 % of all new mortgage advances in Q3 2025, the highest share recorded since mid-2008.
- Earlier in 2025, LTV > 90 % lending was already at 6.7 % in Q1, showing a consistent trend upwards rather than an isolated spike.
While official data do not separately list 100 % LTV mortgage counts, we do know that:
- Mortgages with LTV above 95 % accounted for about 0.5 % of total lending in 2025.
- This confirms that pure no-deposit deals remain rare but are back on the market after years of near-absence.
Another trend is higher leverage overall:
- By late 2025, 44.7 % of new mortgages involved borrowers taking loans at more than four times their annual income, reflecting ongoing affordability pressures.
Taken together, these figures show that high-LTV borrowing is increasingly part of the UK mortgage market, especially for first-time mortgage buyers and those with limited deposit savings.
Looking Ahead: Projections for 2026
Industry forecasts suggest the mortgage market will continue growing in 2026, but with more stability and moderation compared to the strong surge seen in 2025:
- Total gross mortgage lending is expected to rise modestly to around £300 billion in 2026, up from an estimated £288 billion in 2025.
- The number of property transactions is forecast to remain stable or slightly lower, indicating that growth may be driven more by mortgage refinancing and larger average loan sizes than by more buyers entering the market.
- A significant wave of remortgaging activity is anticipated, with around 1.8 million fixed-rate deals set to expire in 2026, potentially boosting overall lending volumes.
- Mortgage arrears are projected to fall by about 5%, suggesting that borrowers are handling debt responsibly even with higher leverage.
While specific forecasts for high-LTV share are not routinely published, these expected trends imply:
- 100 home loans and High-LTV mortgages and are likely to remain available, but not dominate the market.
- Falling interest rates – if they continue to drop could make higher-LTV borrowing more affordable, which might modestly increase uptake among well-qualified buyers.
- Mortgage lenders are expected to remain cautious, maintaining strict affordability and credit assessment standards even as product availability expands.
Should You Consider a No Deposit Mortgage?
Not everyone can afford loans with a 100% home financing or a very high loan-to-value ratio
- For example, raising the interest rates on 90 and above deals by 0.25 to 0.5 or more will usually cover 90 to 100 mortgages with a higher lending risk. This will raise monthly payments.
- If you borrow more, you’ll have to spend more money each month, which is why the affordability test is so strict.
- The risk of negative equity goes up when the value of the property goes down, making it harder to sell or remortgage it in the future.
- Other lenders want mortgage payment protection or mortgage indemnity guarantees, which are extra fees that are currently being paid.
Before applying for a mortgage, it’s a good idea to use a first time buyer mortgage calculator to work out much they you can afford to borrow and how much they can afford to pay each month. This will give you a chance to see what the actual payments will be and, more importantly, to see if they can still afford the loan if rates go up.
Who Benefits Most From No Deposit Home Loans?
Here are a few benefits offered by high LTV mortgages:
- First-time buyers who don’t want to wait years to save up for a deposit can benefit from the small savings that high-LTV mortgages offer.
- Deposits in areas with high prices or markets that are quickly rising are very hard for customers to deal with.
- People taking on self-build projects, as specialist lenders can release money in stages and allow deposits to be timed around the build.
- Home movers, who may rely on the equity in their current property rather than putting down additional savings.
Role of Self-Build Mortgage Lenders
Self-build projects can be harder to manage because they depend on funds being released at the right moments.
High-LTV self-build mortgages can help keep the project moving by supporting cash flow at each stage.
Lenders usually base their decision on the strength of the plans, the experience of the builders, and a clear and realistic project plan for completing the building works.
Risks and How to Mitigate Them
- Try not to stretch your borrowing to the very last pound, especially for short-term fixes or lifestyle upgrades.
- A good mortgage broker can make life easier by helping you find a mortgage that actually fits your situation as a first-time buyer in the UK.
- Use the first time buyer mortgage calculator tools to create scenarios that will help you plan your repayments easily.
- You may have to pay an upfront product fee for high LTV mortgages, so factor in this additional expense.
Conclusion
100% home loans and no-deposit mortgages are becoming more visible in the UK because many people are finding it harder to save for a large deposit. For first-time buyers, UK residents, and self-builders, these options can make buying a home possible when it would otherwise be out of reach.
Even so, mortgage lenders are still cautious. Interest rates are often higher, and they check affordability closely. Before you commit to anything, make sure you understand the repayments and the risks by using a first-time buyer mortgage calculator and an mortgage affordability calculator.
