Quick Answer
The minimum deposit for a mortgage in the UK is typically 5% of the property price. However, putting down a larger deposit (10–20% or more) can improve your chances of approval and give you access to better interest rates.
What Is a Mortgage Deposit?
A mortgage deposit is the amount of money you pay upfront when buying a property.
The rest is borrowed from a lender as a mortgage.
Example:
Mortgage: £237,500
Property price: £250,000
5% deposit: £12,500

How Deposit Size Affects Your Mortgage
Your deposit determines your Loan-to-Value (LTV) ratio.
What Is LTV?
LTV = Mortgage amount ÷ Property value
Example:
- £250,000 property
- £25,000 deposit (10%)
👉 90% LTV
Lower LTV = lower risk = better rates
How Much Deposit Do You Really Need?
While 5% is the minimum, many buyers need more in reality.
You may need a larger deposit if:
- You have bad credit
- Your income is lower
- You have high monthly expenses
- The property is considered higher risk
Deposit Requirements for First-Time Buyers
First-time buyers often start with:
- 5%–10% deposits
- Government schemes (if available)
- Help from family (gifted deposits)
However, lenders will still apply strict affordability checks.
What Is a Gifted Deposit?
A gifted deposit is money given by a family member to help you buy a home.
Lenders usually require:
- A signed declaration
- Proof the money is a gift (not a loan)
Can You Get a Mortgage with No Deposit?
In most cases, no-deposit mortgages are not available in the UK.
However, some niche options exist, such as:
- Family-backed mortgages
- Guarantor mortgages
These still involve risk and strict criteria.
Extra Costs to Budget For
Your deposit is not the only upfront cost.
