Buying your first home in the UK can feel impossible. On a £280,000 home, a 10% deposit is £28,000, and even a 5% deposit is £14,000. But thousands of people manage it every year with the right strategy, the right accounts, and enough time. Here's how to build your deposit from scratch.
How Much Deposit Do You Actually Need?
Most lenders require a minimum of 5% deposit, though 10-15% gets you significantly better mortgage rates. On a £200,000 property: 5% = £10,000, 10% = £20,000, 15% = £30,000. The difference in mortgage interest rates between 5% and 10% deposits can be substantial, which translates to thousands over the mortgage term. Beyond the deposit, budget for: stamp duty (in England and Northern Ireland, first-time buyers pay nothing up to £300,000 and 5% on the portion from £300,001 to £500,000; there is no relief above £500,000), solicitor fees (£1,000-£2,000), survey costs (£300-£700), and moving costs. A realistic total budget is deposit plus £3,000-£5,000 for additional costs. Our stamp duty calculator shows what you would pay.
Use a Lifetime ISA
The Lifetime ISA (LISA) is the most powerful tool for first-time buyers. You can save up to £4,000 per year and the government adds a 25% bonus: up to £1,000 a year. Over 4 years, that's £16,000 saved plus £4,000 in bonuses = £20,000. The rules: you must be 18-39 to open one, the property must cost £450,000 or less, and you must have had the LISA open for at least 12 months before using it. The penalty for withdrawing for any other purpose (except retirement after 60) is 25%, which means you lose more than just the bonus. Only open a LISA if you're confident you'll use it for a first home. The government has consulted on replacing it with a new First Time Buyer ISA, but no launch date has been confirmed, and you can still open and pay into a LISA.
Create a Realistic Savings Plan
Work backwards from your target. If you need £15,000 in 3 years, that's £5,000 per year or £417 per month. Can you afford that? If not, extend the timeline or reduce the target (smaller property, different area, shared ownership). Here's a framework:
- Calculate your target: Property price × deposit percentage + £4,000 for fees.
- Set a timeline: Be realistic. 2-5 years is typical for most first-time buyers.
- Monthly amount: Total target ÷ number of months.
- Automate: Set up a standing order into a LISA and/or savings account on payday.
- Review quarterly: Are you on track? Do you need to adjust the amount, timeline, or target?
Where to Save Your Deposit
Your deposit savings should go into a Lifetime ISA first (up to £4,000/year for the 25% bonus), then overflow into a Cash ISA or high-interest savings account. Don't invest your deposit money in stocks unless your timeline is 5+ years. A market crash the year before you want to buy could wipe out 20-30% of your deposit. For money you need in 1-3 years, cash is king. Look for the best easy-access or fixed-rate savings accounts. At 4% interest, for example, £15,000 earns £600 a year.
Boost Your Savings
If your regular income isn't enough, look for ways to accelerate:
- Reduce your biggest costs: Housing is usually #1. Could you move somewhere cheaper, get a flatmate, or move back with family temporarily?
- Side income: Freelancing, tutoring, selling items, weekend work. Even £200/month extra is £2,400/year.
- Windfalls: Tax refunds, work bonuses, birthday money, inheritance. Direct 100% into the deposit fund.
- Cut subscriptions ruthlessly: Audit every direct debit. Cancel anything you don't actively use.
- Use cashback sites and loyalty schemes: TopCashback, Quidco, and loyalty cards add up over years of spending.
Alternative Routes to Homeownership
If a full deposit feels unreachable, consider these options:
- Shared ownership: Buy 25-75% of a property and pay rent on the rest. Deposit is only needed on your share.
- First Homes scheme (England): Some new-build homes are sold at a 30-50% discount to local first-time buyers, but availability is limited, so check with your local council.
- Family support: Some lenders accept family deposits held in a linked savings account (e.g., Barclays Springboard).
- Guarantor mortgages: A family member guarantees part of the mortgage, allowing you to borrow more with a smaller deposit.
- Right to Buy: If you're a council or housing association tenant, you may be able to buy your home at a significant discount.
FAQ
How long does it take the average first-time buyer to save a deposit?
It varies hugely with income, rent and region. Many buyers take several years, London usually takes longest, and northern England and Wales are typically faster. A savings goal calculator will show how long your own target would take.
Should I overpay my deposit or get on the ladder sooner?
It depends on prices where you want to buy and on mortgage rates. A bigger deposit gets you a better rate and lower monthly payments, but waiting years to save it means paying rent for longer, and prices may rise in the meantime. Compare the monthly cost of both options with our mortgage calculator before deciding.
Can I use a Help to Buy ISA for my deposit?
Help to Buy ISAs closed to new applicants in November 2019. If you already have one, you can still save into it until November 2029 and claim the bonus until November 2030. The Lifetime ISA is now the main alternative.
