Saving for a house deposit is one of the biggest financial goals most people will ever set. In the UK, the average first-time buyer needs around £33,000 outside London and over £100,000 in the capital. This guide breaks down exactly how to get there.
How Much Do You Actually Need?
The deposit size depends on where you buy and the type of mortgage you get.
| Region | Average First-Time Buyer Price | 10% Deposit | 5% Deposit |
|---|---|---|---|
| London | £425,000 | £42,500 | £21,250 |
| South East | £325,000 | £32,500 | £16,250 |
| South West | £275,000 | £27,500 | £13,750 |
| East Midlands | £220,000 | £22,000 | £11,000 |
| West Midlands | £230,000 | £23,000 | £11,500 |
| North West | £195,000 | £19,500 | £9,750 |
| Yorkshire | £185,000 | £18,500 | £9,250 |
| Scotland | £175,000 | £17,500 | £8,750 |
| Wales | £190,000 | £19,000 | £9,500 |
Tip: A larger deposit means a lower loan-to-value (LTV) ratio, which unlocks better mortgage rates. A 25% deposit can save you tens of thousands in interest over the mortgage term compared to a 5% deposit.
Lifetime ISA: Your Most Powerful Tool
The Lifetime ISA (LISA) is the single best way to save for a first home. The government adds a 25% bonus to everything you save, up to £1,000 per year.
How the Lifetime ISA Works
| Detail | Value |
|---|---|
| Annual limit | £4,000 |
| Government bonus | 25% (up to £1,000/year) |
| Can use for | First home (up to £450,000) or retirement |
| Age range | 18-39 to open |
| Penalty for non-qualifying withdrawal | 25% (you lose the bonus and pay extra) |
Worked example: You open a LISA at age 25 and save £333/month (£4,000/year). The government adds £1,000 each year. After 5 years, you have saved £20,000 and received £5,000 in bonuses — a total of £25,000. Combined with interest, you could have £27,000-£28,000.
Worked example 2: A couple both open LISAs and each saves £4,000/year. After 3 years, they have £24,000 in savings plus £6,000 in bonuses — £30,000 total. This covers a 10% deposit on a £300,000 property in many parts of the UK.
Important rules:
- You must be aged 18-39 to open a LISA
- You can save until you are 50
- The property must cost £450,000 or less
- You must use a mortgage (not cash purchase)
- You must have lived in the property for at least 12 months
- You can hold a Cash LISA or Stocks & Shares LISA
Help to Buy: What Remains
The Help to Buy equity loan scheme in England closed to new applicants in 2023. However, some elements still exist:
Schemes Still Available
| Scheme | Status | How It Works |
|---|---|---|
| Help to Buy (Equity Loan) - England | Closed | Government lent 20% (40% in London) as an equity loan |
| Help to Buy (Equity Loan) - Wales | Closed (2024) | Similar to England scheme |
| Shared Ownership | Open | Buy 25-75% of a property, pay rent on the rest |
| First Homes | Open | 30-50% discount on market price for first-time buyers |
| Own New - Rate Reducer | Open | Developer subsidises mortgage rate for first 2-3 years |
Shared Ownership: A Stepping Stone
Shared ownership lets you buy a share of a property (usually 25-75%) and pay rent on the remainder. You can buy more shares over time until you own the property outright.
How Shared Ownership Works
| Detail | Value |
|---|---|
| Minimum share | 25% (some allow 10%) |
| Rent on remaining share | Typically 2.75% of unsold share per year |
| Staircasing | Buy more shares in increments (usually 10%+) |
| Eligibility | Household income under £80,000 (£90,000 in London) |
Worked example: A flat costs £200,000. You buy a 25% share for £50,000 (with a 5% deposit of £2,500). You pay rent of £337.50/month on the remaining 75% (£150,000 × 2.75% ÷ 12). Your total monthly housing cost is much lower than buying outright or renting privately.
Pros:
- Lower deposit needed
- Lower mortgage required
- Can staircase to full ownership
- Still benefit from property price increases
Cons:
- Service charges apply
- Rent on unsold share is not building equity
- Staircasing can be expensive (revaluation needed)
- Harder to sell than a fully-owned property
Rent a Room Scheme
If you own a property (or plan to buy one with a spare room), the Rent a Room scheme lets you earn up to £7,500 per year tax-free from letting a furnished room.
How Rent a Room Works
| Detail | Value |
|---|---|
| Tax-free limit | £7,500 per year |
| Room must be | Furnished |
| Can be used alongside | Lodger or tenant |
| Applies to | Your main home only |
Worked example: You have a spare room in your house. You rent it out for £600/month (£7,200/year). Under the Rent a Room scheme, this is entirely tax-free. If you did not use the scheme, you would pay tax on the amount above the allowance.
Tip: Some mortgage lenders restrict or prohibit lodgers. Check with your lender before taking in a lodger.
Budgeting Tips That Actually Work
The 50/30/20 Rule (Modified for Saving)
| Category | Standard | Aggressive Saver |
|---|---|---|
| Needs (rent, bills, food) | 50% | 50% |
| Wants (socialising, hobbies) | 30% | 20% |
| Savings (deposit fund) | 20% | 30% |
Worked example: You earn £30,000/year (£1,950/month after tax). At the standard 20% savings rate, you save £390/month. At the aggressive 30% rate, you save £585/month.
Practical Budgeting Steps
Step 1: Track every penny for one month. Use an app like YNAB, Money Dashboard, or a simple spreadsheet.
Step 2: Identify your “leak” categories. Common culprits:
- Subscriptions you do not use
- Takeaways and eating out
- Impulse purchases
- Transport (Uber instead of bus)
- Monthly “treats” that add up
Step 3: Set up automatic transfers. On payday, move your savings to a separate account before you can spend it.
Step 4: Review and adjust monthly. Small improvements compound over time.
Realistic Savings Cutting
| Category | Monthly Saving | Annual Impact |
|---|---|---|
| Cancel unused subscriptions | £30-50 | £360-600 |
| Cook at home more | £100-200 | £1,200-2,400 |
| Switch energy provider | £20-40 | £240-480 |
| Use public transport | £50-100 | £600-1,200 |
| Negotiate bills (phone, broadband) | £15-30 | £180-360 |
| Reduce clothes shopping | £50-100 | £600-1,200 |

Regional Price Differences
Where you buy matters enormously. The same deposit goes much further in different regions.
| Region | Average FTB Price | 10% Deposit | Saving at £500/month |
|---|---|---|---|
| London | £425,000 | £42,500 | 85 months (7 years) |
| South East | £325,000 | £32,500 | 65 months (5.4 years) |
| Manchester | £210,000 | £21,000 | 42 months (3.5 years) |
| Birmingham | £220,000 | £22,000 | 44 months (3.7 years) |
| Leeds | £195,000 | £19,500 | 39 months (3.3 years) |
| Edinburgh | £230,000 | £23,000 | 46 months (3.8 years) |
| Glasgow | £165,000 | £16,500 | 33 months (2.8 years) |
| Cardiff | £195,000 | £19,500 | 39 months (3.3 years) |
Tip: If you work remotely, consider buying in a cheaper region. A £50,000 deposit in Glasgow gets you a much better property than the same deposit in London.
Additional Tips for First-Time Buyers
Check your credit score early. Lenders will check it. A good score can mean a better mortgage rate. Start building it 6-12 months before you plan to buy.
Get a mortgage Agreement in Principle (AIP). This shows sellers you are a serious buyer and helps you understand how much you can borrow.
Budget for extra costs. Beyond the deposit, you need:
- Solicitor fees: £1,000-£3,000
- Survey: £300-£1,500
- Stamp duty: £0 for first-time buyers under £300,000 (up to £500,000 threshold)
- Moving costs: £500-£2,000
- Mortgage fees: £0-£2,000
Consider a joint mortgage. Buying with a partner, friend, or family member can make it much more affordable. Be aware of the legal and financial implications.
Look into local schemes. Some councils and housing associations offer additional support for first-time buyers in their area.
The Bottom Line
Saving for a deposit is a long-term goal that requires discipline and planning. Use a Lifetime ISA to get free money from the government, cut your spending where you can, and be realistic about your timeline. The deposit is just the start — make sure you can also afford the monthly mortgage payments, maintenance, and running costs of homeownership.
