Buying your first home in London can feel like a massive financial leap, but with the right approach, it’s more achievable than many people realise.
With property prices high and deposit requirements steep, getting onto the property ladder starts with smart saving strategies that suit your personal circumstances.
At The Mortgage and Protection Hub, we help first-time buyers across London understand their mortgage options, explore government support schemes, and create a realistic savings plan tailored to their goals.
If you’re ready to start saving for your first home, here’s what you need to know.
How Much Do You Need to Save?
For most first-time buyers, the biggest hurdle is the deposit.
Most lenders require a minimum of 5% of the property’s value, although a larger deposit (such as 10% or 15%) can secure better mortgage rates and lower monthly repayments.
Let’s say the purchase price of a property is £400,000. A 10% deposit would be £40,000. But remember, you also need to factor in extra costs, like:
- Legal and valuation fees
- Stamp duty (first-time buyers pay none up to £425,000)
- Moving expenses
- Furniture and renovations
By planning ahead for these additional costs, you’ll avoid surprises and stay in control of your budget.
Open a Dedicated Savings Account
A separate savings account is one of the most important tools when building your deposit. Options to consider include:
- Lifetime ISA – Save up to £4,000 per tax year and receive a 25% government bonus. You must be under 40 to open one, and the money must go towards buying your first home or retirement.
- Fixed term savings – These often offer higher interest but may limit access to funds.
- Easy-access accounts – Great for flexibility if you think you might need to dip into savings occasionally.
Avoid withdrawing money unless absolutely necessary. Keeping your deposit ring-fenced makes it easier to stay disciplined and track your progress.
Set a Realistic Monthly Budget
Review your income and expenses to create a clear, consistent savings plan. Small changes in your spending habits can add up quickly.
- Set a monthly savings goal and move money automatically via direct debit.
- Cut back on non-essential costs like subscriptions or takeaways.
- Consider putting unexpected income (bonuses, refunds, birthday money) into your deposit fund.
Even saving an extra £100 per month can make a huge difference over time.
Automate Your Savings and Track Your Progress
Make Saving Effortless with Direct Debits
Once your monthly budget is set, you can turn intention into action by setting up an automatic direct debit from your current account to your dedicated savings account on payday.
This “pay yourself first” approach removes temptation, smooths out your cash flow and keeps your deposit savings growing even when other expenses crop up.
Many first-time buyers find that automating transfers helps them stay on track to hit their savings goals without feeling the pinch.
Track Your Deposit Fund in Real Time
Use a simple spreadsheet or a budgeting app to log every payment into your Lifetime ISA, fixed term account or easy-access pot.
Watching the balance climb month by month keeps motivation high and shows how close you are to the magic figure lenders require for a mortgage deposit.
Regularly compare your progress with the average deposit needed for the purchase price you have in mind so you know when you can realistically start viewing properties.
Celebrate Milestones and Keep Momentum
Break your larger target into smaller markers, such as each extra £5,000 saved or every percentage point of the purchase price secured.
Celebrate each milestone with a low-cost reward, then refocus on the next one. This simple habit turns a daunting total into manageable steps and keeps your savings journey enjoyable.
Key takeaway: Automating payments and monitoring your progress transforms saving from an occasional task into a steady habit, helping first-time buyers in London reach their house deposit sooner and secure better mortgage deals when they apply.
Explore Government Support Schemes
There are several government schemes aimed at helping first-time buyers in London:
- Shared Ownership – Buy a share of a home and pay rent on the rest. Ideal for those with smaller deposits.
- First Homes Scheme – Purchase a new build property at a 30%–50% discount if eligible.
- Stamp Duty Relief – Save money on upfront taxes if your property costs under £425,000.
These schemes can reduce the amount you need to save and improve your access to better mortgage deals.
Consider a Gifted Deposit
If a family member is in a position to help, a gifted deposit could significantly speed up the process.
- Most lenders accept this, provided a formal letter confirms the gift is not a loan.
- A higher deposit can reduce your loan to value ratio, unlocking better mortgage terms and potentially lower interest rates.
Even a small contribution from family can make a big impact when combined with your savings.
Look for Ways to Earn Extra Cash
If you’re struggling to reach your savings goals through budgeting alone, think about ways to earn extra money:
- Take on freelance work or a part-time side hustle
- Sell unused items online
- Look for temporary weekend jobs or tutoring opportunities
Put any extra income directly into your deposit savings to stay on track.
Know What You Can Afford
It’s easy to get swept up in property searches and dream homes, but make sure you focus on what you can realistically afford.
- Use affordability calculators to see how much you could borrow
- Consider less expensive boroughs or shared ownership options
- Factor in all ongoing costs, from mortgage repayments to household bills
Starting with a modest first home is often the best way to get on the ladder, especially in London’s competitive market.
Speak to a Mortgage Adviser Early
Talking to a mortgage adviser early in your journey can give you clarity and confidence. They can:
- Help you set savings goals based on your target property
- Advise on lender eligibility criteria
- Explain how your credit rating, deposit size, and income affect your options
- Recommend the right first-time buyer schemes for your circumstances
You don’t need to wait until you’ve saved the full deposit, getting advice early can help shape a smarter saving plan.
