What is the minimum deposit for a house in the UK?

The minimum deposit is typically 5% of the property price. For a £250,000 house, that's £12,500. However, rates are much better with larger deposits, and some lenders require 10% minimum.

Is a 10% deposit enough to buy a house?

Yes — 10% is a solid deposit that gives you access to more lenders and better rates than 5%. You'll get significantly lower interest rates than with 5%, though 15-25% unlocks even better deals.

How much deposit do first-time buyers need?

First-time buyers typically need at least 5% deposit. Some government schemes can help, and there are specific first-time buyer mortgages available. Most first timers put down 5-15%.

Do I need a bigger deposit for a buy-to-let?

Yes — buy-to-let mortgages typically require a minimum 25% deposit, with better rates available at 40%+. Lenders see BTL as higher risk than residential mortgages.

Deposit Size Decision

When 5% Makes Sense

✅ First-time buyer wanting to get on ladder ✅ Confident income will increase ✅ Plan to overpay or remortgage to lower LTV ✅ Market conditions favour buyers

When to Save More

✅ Can wait 1-2 years to save more ✅ Want lower monthly payments ✅ Prefer financial security ✅ Buying new build (often need 10-15% anyway)

Key Takeaways

Point	Detail
Minimum	5% for most, 10-15% for some properties
Ideal	10-15% balances rate vs waiting time
Best rates	25%+ deposit
Buy-to-let	25% minimum
First-time buyers	Use LISA for 25% bonus
Don’t forget	Other buying costs need budget too
