How to Save for Your First Home in the UK

Saving for a house deposit is the first and often the most challenging step on the road to homeownership. With UK property prices averaging around £290,000 in early 2026, even a 10% deposit means saving £29,000. While that figure can feel daunting, having a clear plan, using the right accounts, and taking advantage of government schemes can make it much more achievable. This guide covers everything you need to know.

How Much Deposit Do You Need?

Most lenders require a minimum deposit of 5% of the property price. However, the more you can put down, the better your mortgage rate will be. Here is how deposit size typically affects your options:

• 5% deposit: The minimum accepted by most lenders. Mortgage rates will be higher because the lender is taking on more risk. For a £250,000 property, this means saving £12,500.
• 10% deposit: A significant improvement in available rates. You move into the 90% loan-to-value (LTV) bracket, which offers noticeably lower rates than 95% LTV products.
• 15% deposit: Access to even better rates. The 85% LTV bracket is often where you start seeing competitive deals from major lenders.
• 20% or more: The best rates are typically available at 80% LTV or lower. A 20% deposit on a £250,000 property is £50,000 — a stretch for many buyers but worth aiming for if your timeline allows.

Remember that a larger deposit does not just mean better rates — it also means lower monthly payments and less total interest paid over the life of the mortgage. Every extra percentage point you save can make a real difference.

Best Savings Accounts for a House Deposit

Where you keep your deposit savings matters. Here are the best options in 2026:

Lifetime ISA (LISA)

The Lifetime ISA is the standout choice for most first-time buyers. You can save up to £4,000 per year and the government adds a 25% bonus - that is up to £1,000 in free money every year. Over four years of maximum contributions, you would have £16,000 in savings plus £4,000 in bonus money, totalling £20,000 before interest.

To use a LISA for a property purchase, the property must cost £450,000 or less, you must be a first-time buyer, and the account must have been open for at least 12 months. You must be aged 18-39 to open one. If you withdraw money for any reason other than buying a qualifying property (or after age 60), you face a 25% penalty on the amount withdrawn, which means you lose your bonus and a portion of your own contributions. Note that the LISA scheme is currently under government consultation.

Cash ISA

A Cash ISA allows you to save up to £20,000 per year tax-free. While there is no government bonus, you do not pay income tax on the interest earned, which becomes significant at higher savings balances. The ISA allowance is shared across all ISA types — so if you contribute £4,000 to a LISA, you have £16,000 remaining for your Cash ISA allowance.

Regular Saver Accounts

Some banks offer regular saver accounts with higher interest rates - often 5-7% - provided you deposit a set amount each month (typically £25-£300). While the maximum balance is usually capped, these accounts are an excellent way to build the habit of saving and earn above-average interest in the meantime.

Fixed-Rate Savings Accounts

If you know you will not need access to your savings for a set period, a fixed-rate bond can offer higher interest rates than easy access accounts. Terms typically range from one to five years. The trade-off is that your money is locked away and you cannot access it early without losing interest or paying a penalty.

Government Schemes That Boost Your Deposit

Beyond the LISA, there are other government initiatives that can help first-time buyers:

• Shared Ownership: Buy a share of a property (25-75%) with a smaller deposit and pay rent on the remaining share. You only need a deposit on the share you are buying - for example, 5% of a 40% share of a £250,000 property is just £5,000.
• First Homes: New-build properties sold at a discount of 30-50% to first-time buyers. The discount is locked in for future sales too.
• Stamp Duty relief: First-time buyers pay no stamp duty on properties up to £300,000 and reduced rates up to £500,000, saving up to £10,000.

Practical Budgeting Tips

Building a deposit requires consistent saving, and that means getting serious about your budget. Here are proven strategies:

• Pay yourself first: Set up a standing order to transfer money into your savings account on payday, before you have a chance to spend it. Treat your savings contribution like a non-negotiable bill.
• Track your spending: Use a budgeting app or spreadsheet to track every penny for at least one month. Most people are surprised at how much goes to small, unnoticed expenses like subscriptions, takeaways, and impulse purchases.
• Cut the big three: Housing, transport, and food make up the majority of most people's spending. Consider downsizing your rental, switching to a cheaper commute, or meal planning to make the biggest impact.
• Reduce subscriptions: Audit your direct debits and cancel anything you do not actively use. Streaming services, gym memberships, and app subscriptions can add up to hundreds of pounds per month.
• Increase your income: Consider asking for a pay rise, taking on overtime, freelancing on the side, or selling items you no longer need. Every extra pound goes directly towards your goal.
• Use the 50/30/20 rule: Aim to spend 50% of your take-home pay on needs, 30% on wants, and 20% on savings. If you can push savings to 30% or higher, you will reach your goal significantly faster.

Planning Your Timeline

Understanding how long it will take to save your deposit helps you set realistic expectations and stay motivated. Here is a rough timeline based on different savings rates for a £25,000 deposit:

Adding a LISA bonus can shave months off these timelines. Saving £333 per month into a LISA gives you £4,000 per year in contributions plus a £1,000 bonus - that is £5,000 per year towards your deposit with only £4,000 coming from your own pocket.

Be realistic about your timeline but also ambitious. Set milestones (£5,000, £10,000, £15,000) and celebrate each one to maintain motivation over what can be a multi-year savings journey.

Common Mistakes to Avoid

• Not starting a LISA early enough: The 12-month waiting period means you should open a LISA as soon as possible, even with a small initial deposit.
• Keeping savings in a current account: Even in a low-rate environment, moving your savings to a higher-interest account over several years adds up to hundreds or thousands in extra interest.
• Dipping into savings: Keep your house deposit fund separate from your everyday spending and emergency fund. Make it slightly harder to access so you are less tempted.
• Not budgeting for additional costs: Your deposit is not the only expense when buying a home. Budget separately for solicitor fees, surveys, moving costs, and furnishing.

When to Seek Professional Advice

If you are unsure about the best savings strategy for your situation, a financial adviser can help you optimise your approach. They can advise on the best combination of accounts, tax-efficient saving, and help you build a realistic plan. This is especially useful if you have a complex financial situation such as self-employment income, existing investments, or debts that need managing alongside your savings.
