The deposit is often the biggest hurdle for first-time buyers. While the headline figures can be intimidating, there are more options available in 2026 than ever before. This guide breaks down exactly how much you need and why it matters.
The 5% Minimum
In 2026, many lenders still offer mortgages with just a 5% deposit. This is the minimum required for a standard residential mortgage. For a £300,000 property, this means a deposit of £15,000. While this makes getting on the ladder faster, it's important to understand the trade-offs.
What is LTV?
LTV stands for 'Loan to Value'. If you have a 5% deposit, your LTV is 95%. Lenders use this ratio to determine your interest rate - the lower the LTV, the lower the risk and the better the rate.
The 'Sweet Spot' Thresholds
Interest rates don't drop gradually; they drop in tiers. You'll see significant improvements in the deals available to you at these LTV thresholds:
- 90% LTV (10% Deposit): A noticeable drop in rates from 95% LTV.
- 85% LTV (15% Deposit): Access to much more competitive products.
- 60% LTV (40% Deposit): Usually where the very best market rates are found.
Ways to Boost Your Deposit
If you're struggling to save the full amount, consider these common 2026 strategies:
Lifetime ISA (LISA)
The government adds a 25% bonus to your savings (up to £1,000 per year) if used for your first home.
Gifted Deposits
Family members can 'gift' you a portion or all of your deposit. Lenders will require a signed letter confirming it's not a loan.
Don't Forget the 'Hidden' Costs
Your deposit isn't the only cash you'll need. Make sure you have a separate 'buffer' for:
- Solicitor/Conveyancing fees (£1,000 - £2,000)
- Property Survey (£400 - £1,000)
- Mortgage Arrangement fees (£0 - £1,500)
- Removal costs and initial furniture
