Make sure you understand your finances before saving for a deposit

Before you start saving for a house deposit, it’s important to get a clear picture of your financial situation. Look through all your accounts, including current accounts, credit cards, and savings accounts, to understand exactly how much money you have and whether you’re carrying any debt. If you’re buying or saving with a partner, review both of your finances together so you know your combined starting point. Make sure to close any old or inactive accounts you no longer use, as these can affect your credit profile.

Once you have a full overview of your finances, it becomes much easier to plan your deposit savings and set realistic goals.

What is a House Deposit?

Before you begin your home-buying journey, it's important to know how deposits work.

A house deposit is the upfront amount you pay when buying a home. It forms part of your overall purchase price and impacts how much you need to borrow through a mortgage. Most lenders require at least 5% - 10%, but the more you can put down, the better your mortgage rates and monthly payments are likely to be.

For Shared Ownership, deposits can be much lower because they’re based only on the share you’re buying.

How Much House Deposit Do I Need?

The deposit required to buy a home can vary, so it's important to know what affects the ammount you'll need.

The deposit you need depends on:

Your mortgage lender
The type of home
Whether you’re buying a full home or a Shared Ownership share

For a full market sale, many buyers aim for 10% - 15% to access better deals.

With Shared Ownership, deposits are often much smaller — sometimes as little as £3,000 - £5,000, because they’re calculated on the value of your share rather than the whole home.

Shared Ownership Deposits

How much deposit do I need for a shared ownership property?

Shared Ownership deposits are often much lower than those needed for buying a home outright. Instead of saving a deposit based on the full property value, you only need a deposit for the share you’re purchasing — for example, 10%, 25%, 40% or 50%. This means many buyers secure a home with a deposit of just a few thousand pounds.

The exact amount will depend on your mortgage lender and the share you choose, but Shared Ownership typically makes getting onto the property ladder more accessible and affordable for first‑time buyers.

How to Save a House Deposit

How to stay on track when saving your deposit

Saving for a deposit can feel overwhelming, but breaking the process into manageable steps makes it much easier. Setting up a dedicated savings account, reviewing your monthly spending, and reducing high‑interest debts can all help free up more money to save. You can also take advantage of government schemes like the Lifetime ISA, and automate monthly savings so you’re consistently building your pot. Even small, regular contributions add up quickly over time.

Can Your Deposit Affect Your Mortgage?

How your deposit affects your mortgage and overall affordability

Your deposit has a direct impact on the mortgage you can get, and understanding this is key when planning your home‑buying budget. In the UK, a larger mortgage deposit can unlock better interest rates, reduce your monthly repayments, and increase the number of lenders willing to offer you a mortgage. It also strengthens your affordability assessment, giving you a better chance of approval.

For Shared Ownership buyers, the deposit requirements are often much smaller, making it easier to secure a mortgage with a lower upfront cost. This makes Shared Ownership a popular option for first‑time buyers looking to get on the property ladder with a more achievable deposit amount.
