How much deposit do I need as a first-time buyer?
In the UK, lenders typically require a minimum 5% deposit of the property’s value, but many advisers recommend aiming for around 10% to secure better mortgage deals and lower interest rates. Larger deposits can improve your options and rates. Saving plans, budgeting and government help like a Lifetime ISA can make reaching your deposit goal easier.
For most first time buyers, the biggest barrier isn’t finding the perfect home, it’s saving the deposit.
Let’s follow Emma, a 29 year old first time buyer from Manchester. She worked out how much she needed to save, built her deposit and finally bought her dream home.
Step 1: Understanding what lenders want
When Emma first started browsing property listings, she quickly realised she needed to understand how deposits work.
Most lenders in England will accept a minimum deposit of 5% of the property value. For Emma’s £200,000 home, that would be £10,000.
However, mortgage brokers often recommend aiming for around 10%, about £20,000 in Emma’s case, to access a wider choice of mortgage deals and better interest rates.
Step 2: Saving for the deposit
This is the toughest but most rewarding part of any homeowner’s journey.
1. Setting a savings goal
Emma decided to save £20,000 over 18 months. That meant putting aside about £1,100 per month when including bonuses and some side income.
To make it less intimidating, she broke it down further:
- £250 per week or
- £36 per day (roughly the cost of a night out or a takeaway).
2. Building a realistic budget
Emma started by tracking her spending using a budgeting app. Within the first month, she realised she was spending nearly £250 a month on food deliveries and coffee.
She made small lifestyle swaps:
- Cooked at home and prepped lunches for work.
- Cancelled unused subscriptions (saving £40/month).
- Moved to a SIM only mobile plan (saving £25/month).
- Shared streaming services with her sister.
In total, she freed up about £400 a month, which she redirected straight into her deposit fund.
3. Using a Lifetime ISA
Emma opened a Lifetime ISA (LISA). A government savings account that gives you a 25% bonus on what you save, up to £4,000 per year.
Here’s how it helped:
- She deposited £4,000 each tax year.
- The government added £1,000 in bonuses annually.
- Over two years, that’s £2,000 in free money toward her deposit.
- This meant Emma only needed to personally save £18,000 to hit her £20,000 goal.
4. Side hustles and extra income
To boost her savings, Emma picked up freelance social media work on weekends. Even earning an extra £300 per month added up to £4,000 over the year.
She also sold old clothes and furniture online, earning another £600.
5. Keeping her money safe and separate
Emma opened a dedicated house fund savings account with a high interest rate and automated her transfers right after payday.

Step 3: Reaching the goal
After 18 months, Emma had hit her £20,000 target. £18,000 from her own savings and £2,000 from government bonuses.
| Source | Amount Saved |
|---|---|
| Monthly savings | £14,400 |
| Freelance work & side income | £3,600 |
| Lifetime ISA bonus | £2,000 |
| Total deposit | £20,000 |
When she finally transferred that deposit to her solicitor, it felt like all her hard work had paid off.
Step 4: Buying the home
With a 10% deposit ready, Emma’s mortgage application was smooth. She secured a lower interest rate, which saved her about £120 per month compared with a 5% deposit deal.
Within weeks, they accepted her offer on a charming two-bedroom terrace, her very first home.
