It's called 'My First Mortgage' and it's designed specifically for first-time buyers who've got a smaller deposit but can comfortably afford the monthly payments.
This is genuinely significant. Santander is the UK's fourth-largest mortgage lender, and when a bank of that size moves into territory that's traditionally been the preserve of smaller building societies, others tend to follow. We could be looking at the start of a real shift in what's available to first-time buyers.
But before you get too excited, let's look at what this product actually offers, who it's really designed for, and the genuine risks you need to understand.
What Santander is Offering
The headline figures are straightforward: you can borrow up to 98% of the property value with a minimum deposit of £10,000. It's a five-year fixed rate at 5.19%, with no product fee, a free valuation, and £250 cashback on completion. Maximum borrowing is £500,000, and the longest term available is 40 years.
One particularly important feature: gifted deposits are accepted. This is a bigger deal than it might sound. About half of first-time buyers in the UK receive some help from family towards their deposit. The only other 98% product currently on the market – Skipton's Track Record mortgage – is primarily designed for people who've been renting and uses their rental history to assess affordability. Santander's approach is more traditional, using standard income multiples (up to 4.45 times salary) but with a much smaller deposit requirement.
The Restrictions You Need to Know About
This is where things get more selective. Above 95% LTV, Santander will only lend on existing houses. That means:
Flats are excluded – if you're looking at apartments, maisonettes, or anything with a share of freehold, you'll need a 5% deposit minimum and would be looking at their 95% products instead.
New builds are excluded – again, you'd need 5% for a new build house with Santander. This reflects a consistent pattern across lenders who view new builds as carrying slightly more risk at very high LTVs.
Self-employed buyers aren't eligible for this specific product, though Santander does offer other options for self-employed borrowers at lower LTVs.
Northern Ireland and shared ownership are also excluded.
What this means in practice is that if you're a first-time buyer in a city like Manchester, Birmingham, Leeds or London where most entry-level properties are flats, this particular product isn't available to you. Two-thirds of Santander's first-time buyers last year purchased houses rather than flats, which is why they've designed the product this way – but it does limit who can actually use it.
Understanding the Real Cost
Let's be clear about the trade-off here. Borrowing more means paying more. On a typical purchase, you might be looking at around £100 more per month compared to a 95% mortgage at a lower rate. Over a five-year fix, that adds up to roughly £6,000 in additional payments.
However, you'd also have needed around £4,000 less for your deposit. So the real additional cost of that smaller deposit is closer to £2,000 over five years. Whether that's worth it depends entirely on your circumstances – specifically, how long it would take you to save that extra £4,000 while paying rent, and what house prices might do in the meantime.
Santander's own research shows the average first-time buyer with them put down a deposit of more than £85,000 last year. That figure can feel completely unattainable if you're trying to save while paying rent, covering bills, and possibly managing childcare costs. This product is designed to provide an alternative route for people who can afford monthly payments but struggle to build a large deposit.
The Risks You Must Understand
This is the section that matters most, and it's worth reading carefully.
Negative equity risk is real.
If you buy a £280,000 house with a 96% mortgage, you own roughly £10,000 of equity. If property prices drop by just 5-6% over the five-year fixed term – which is entirely possible – you could find yourself owing more than the house is worth. This isn't a theoretical concern; it's happened before and it can happen again.
Remortgaging could be difficult.
When your five-year fix ends, if your loan-to-value is still very high or you're in negative equity, your options for remortgaging will be limited. Most competitive mortgage deals are available at 90% LTV or below. You might find yourself stuck on a higher rate because you can't access better products.
Selling could be complicated.
If you need to move during those five years – job relocation, relationship changes, family needs – and your house is worth less than what you owe, you'd need to bring cash to the table to complete the sale. That's a difficult position to be in.
You're locked in.
The five-year fix comes with early repayment charges, which is standard for fixed-rate mortgages. But combined with the potential for negative equity, it means you really need to be confident this is a long-term move.
Mortgage industry experts are clear on the best approach here: treat this as a longer-term plan, keep a financial buffer, and where possible use overpayments to bring your loan-to-value down towards 95% or 90% over time. That's where pricing typically gets more competitive when you come to remortgage.
Who This Mortgage is Actually Designed For
Reading between the lines, Santander has a specific type of buyer in mind:
You're employed (not self-employed)
You're looking at buying a house, not a flat
You've got £10,000 saved or gifted
You want to get on the property ladder now rather than spending another few years saving while rental costs keep rising
You're comfortable committing to this property for at least five years
If that describes you, this could be a genuine opportunity. If it doesn't, there may be other options that fit better.
Why Getting Advice Matters
Products like this are exactly why working with a mortgage broker makes sense. A broker can stress test your affordability, check all the criteria properly, compare this against other options you might not have considered, and help you plan for what happens at the end of the fixed rate so you're not caught out later.
The difference between this product working well for you or becoming a financial headache often comes down to whether it was the right fit in the first place. That's not something you can always figure out from a website or comparison tool – it needs proper consideration of your individual circumstances.
What This Means for the Market
When Santander moves, other lenders pay attention. Halifax, Nationwide, and NatWest will all be watching how this product performs. If it's successful, expect to see similar offerings appear over the coming months. This could be the beginning of more choice and competition at the higher LTV end of the market, which has been limited for a long time.
For now, if you're a first-time buyer who's been frustrated by the deposit barrier, it's worth exploring whether this – or any of the other high-LTV options now available – could work for your situation.
