One of the biggest hurdles for first-time buyers or anyone looking to buy a home is coming up with the deposit. The amount you need to save for a mortgage deposit can vary significantly depending on factors like the property price, the type of mortgage, and your financial circumstances. In this guide, we’ll walk you through everything you need to know about mortgage deposits in the UK, including how much is typically required, ways to save, and tips for getting the best deal.

What Is a Mortgage Deposit?
A mortgage deposit is the amount of money you pay upfront towards the purchase of your property, which is not borrowed from the bank or lender. It represents a percentage of the total property price and is an essential part of securing a mortgage. The larger the deposit, the better the mortgage deal you are likely to secure, as it reduces the amount you need to borrow and shows lenders that you’re financially responsible.
How Much Deposit Do I Need for a Mortgage?
In the UK, the minimum deposit required for a mortgage typically starts at 5% of the property’s value. However, this is only available for certain types of mortgages and might not always be the best option. Here are some common deposit amounts and the implications for your mortgage:
1. 5% Deposit (95% Loan-to-Value)
What it is: A 5% deposit means you borrow 95% of the property value.
Who it’s for: First-time buyers or those with a smaller budget.
Pros: Easier to save up for a smaller deposit.
Cons: Higher monthly repayments, and you may face higher interest rates. Lenders may offer fewer deals with this low deposit.
2. 10% Deposit (90% Loan-to-Value)
What it is: A 10% deposit means you borrow 90% of the property value.
Who it’s for: Buyers who can afford to save a bit more and want to access a wider range of mortgage deals.
Pros: A more affordable monthly repayment than with a 5% deposit, and it may unlock access to better mortgage rates.
Cons: Still relatively high borrowing, and you'll need to save more compared to a 5% deposit.
3. 15% Deposit (85% Loan-to-Value)
What it is: A 15% deposit means you borrow 85% of the property value.
Who it’s for: Those who can afford to save a larger deposit and want to access even more competitive mortgage deals.
Pros: More attractive mortgage deals with lower interest rates.
Cons: Requires more savings upfront, but it can result in significant savings on interest over the life of the loan.
4. 20% Deposit (80% Loan-to-Value)
What it is: A 20% deposit means you borrow 80% of the property value.
Who it’s for: Buyers who can save up a substantial amount and want to get the best possible deals.
Pros: The best mortgage rates and lowest monthly repayments. A higher deposit can also increase your chances of getting approved.
Cons: Requires significant savings, but the long-term savings on interest can make it worthwhile.
5. 40% Deposit (60% Loan-to-Value)
What it is: A 40% deposit means you borrow 60% of the property value.
Who it’s for: Those looking for the most favourable mortgage rates or who have substantial savings.
Pros: Very low monthly repayments and the best rates on the market.
Cons: Requires a large deposit, which is often only achievable for those with significant financial resources.
Can I Get a Mortgage with a Smaller Deposit?
Yes, it's possible to get a mortgage with a smaller deposit, but the options may be limited. A 5% deposit (95% loan-to-value) is available, but these mortgages often come with higher interest rates, which means you could pay more over the term of your loan. Some government schemes, such as the Help to Buy initiative, may also allow you to secure a mortgage with a smaller deposit.
However, it’s important to be aware that a smaller deposit increases the risk for the lender, which is why they may charge higher interest rates or offer fewer options.
What Factors Affect the Size of My Deposit?
There are several factors that can influence how much deposit you need for a mortgage:
Property price: The higher the property value, the larger your deposit will need to be.
Your financial situation: Lenders will assess your income, savings, credit score, and employment status to determine how much they’re willing to lend and what deposit is required.
The type of mortgage: Some mortgages, like first-time buyer mortgages, may have lower deposit requirements or government-backed support.
Lender’s criteria: Different lenders may offer different deposit requirements based on their own criteria, so it’s important to compare mortgage deals.
How Can I Save for a Mortgage Deposit?
Saving for a mortgage deposit can seem like a daunting task, but with the right approach, it’s achievable. Here are some strategies to help you save:
Set up a dedicated savings account: Use a high-interest savings account or a Lifetime ISA (LISA) to maximise your savings and receive a government bonus (for first-time buyers).
Cut back on unnecessary spending: Create a budget and reduce non-essential expenses, such as dining out, subscriptions, or impulse purchases.
Increase your income: Consider taking on extra work or finding ways to increase your earnings, such as freelancing or selling unwanted items.
Consider family help: Some people receive gifts or loans from family members to help with their deposit, but it’s important to consider the terms of this assistance and whether it’s feasible.
Final Thoughts
The deposit you need for a mortgage in the UK depends on several factors, including the property value, the type of mortgage, and your financial situation. While the minimum deposit is typically 5%, a larger deposit can help you secure better mortgage deals and lower monthly payments.
It’s important to weigh up your options and choose a deposit level that suits your budget and long-term financial goals. Whether you’re a first-time buyer or looking to move up the property ladder, taking the time to save for a larger deposit can save you money in the long run.
