First-time buyers usually need a minimum deposit of 5% of the purchase price, which is £12,500 on a £250,000 home. Lenders price by loan-to-value bands, so a 10% or 15% deposit normally gets you a lower rate than a 5% one. Here is how deposits work, and the schemes that can help if you are still saving.
Purchasing your first home is a significant milestone, and understanding the deposit requirements makes the whole process smoother. In the UK, the minimum deposit for first-time buyers typically starts at 5% of the property’s value. However, aiming for a larger deposit can offer several advantages.

Minimum Deposit Requirements
While a 5% deposit is generally the minimum required, some lenders may have higher requirements, especially during economic uncertainties. For instance, certain lenders might insist on at least a 10% deposit.
It’s essential to research and consult with mortgage advisors to understand specific lender criteria.
Average Deposit Among First-Time Buyers
According to UK Finance data, the average first-time buyer deposit in England is around 22% of the purchase price, although plenty of buyers put down far less.
This percentage can vary based on factors like property location and individual financial circumstances.
Benefits of a Larger Deposit
A strong credit score makes a big difference. Lenders use your credit history to assess how reliably you’ve managed debt in the past. The higher your score, the better your chances of being offered a larger loan at a more competitive rate. If your score is less than perfect, don’t worry; there are still options, but the amount you can borrow may be slightly lower.
Deposit Size
Why Using a Mortgage Broker Is Key for First-Time Buyers
Saving for a deposit larger than the minimum required can be beneficial:
- Better Mortgage Rates: Lenders often offer more competitive interest rates to buyers who can provide a larger deposit, reducing monthly repayments.
- Increased Borrowing Power: A substantial deposit can enhance your mortgage affordability, potentially allowing you to purchase a more expensive property.
- Lower Loan-to-Value (LTV) Ratio: A higher deposit decreases the LTV ratio, which can result in more favorable mortgage terms.
Government Schemes to Assist First-Time Buyers
To support first-time buyers in accumulating deposits, the UK government offers several schemes:
- Lifetime ISA (LISA): Individuals aged 18-39 can save up to £4,000 annually, with the government adding a 25% bonus, up to £1,000 per year. This can significantly boost your deposit savings over time.
The Scottish Sun
- Deposit Unlock Scheme: This scheme let first-time buyers purchase new-build homes with a 5% deposit, but it closed to new completions in April 2026. Current alternatives include Own New Rate Reducer and New Build Boost.
