Deposit Requirements for Buying a House

At Towerstone, we provide specialist property accountancy services for homeowners, landlords, and property investors. We have written this article to explain typical deposit requirements and options, helping you make informed decisions.

This is one of the first questions almost everyone asks when they start thinking about buying a home. It sounds simple but the answer depends on far more than a single percentage. Your deposit requirement is shaped by your circumstances the type of buyer you are the lender you choose and the wider housing market at the time you apply.

In the UK there is no single fixed deposit rule. Some buyers need very little upfront cash while others need a substantial amount. Understanding why that difference exists helps you plan realistically and avoid disappointment later.

In this guide I will explain how deposits work in the UK what lenders usually expect how different buyer types are treated and what options exist if your savings are limited. This is written in clear UK English and reflects how mortgage lending works in practice.

What a Deposit Actually Is

A deposit is the part of the property price you pay from your own money. The rest is usually funded by a mortgage.

If you buy a £250,000 house and put down a £25,000 deposit you borrow £225,000. That means your deposit is 10 percent of the purchase price and your mortgage covers the remaining 90 percent.

Lenders look closely at this split because the deposit reduces their risk. The more you put in the safer the loan appears from the lender’s perspective.

The Minimum Deposit Most Buyers Need

For most buyers in the UK the minimum deposit is 5 percent of the purchase price.

This means:

£200,000 house needs at least £10,000

£300,000 house needs at least £15,000

These 95 percent mortgages do exist but they are not available to everyone and the interest rates are usually higher.

A 5 percent deposit is often the entry point rather than the ideal position.

Why Many Buyers Aim for 10 Percent

A 10 percent deposit is very common and often more achievable than people expect.

At this level:

£250,000 house needs £25,000

£300,000 house needs £30,000

With a 10 percent deposit you usually get access to:

More mortgage products

Better interest rates

Greater lender flexibility

Many lenders view 10 percent as a more comfortable starting point especially for first time buyers.

Deposits of 15 to 20 Percent

If you can put down 15 or 20 percent your position improves further.

At this level:

Interest rates are usually lower

Monthly payments are reduced

Mortgage approval can be easier

For example a 20 percent deposit on a £300,000 house would be £60,000. This reduces the loan significantly and lowers long term interest costs.

While not essential this level of deposit gives you strong buying power.

First Time Buyer Deposit Requirements

First time buyers are often able to buy with smaller deposits than other buyers.

Many lenders and government schemes are designed specifically for first time buyers.

In practice:

5 percent deposits are most common for first time buyers

10 percent deposits give more choice and stability

Being a first time buyer also helps because you have no chain which lenders and sellers often prefer.

How Loan to Value Affects Your Deposit

Lenders use something called loan to value often shortened to LTV.

This is the percentage of the property price that you borrow.

For example:

95 percent LTV means a 5 percent deposit

90 percent LTV means a 10 percent deposit

80 percent LTV means a 20 percent deposit

Lower LTV usually means lower risk for the lender and better mortgage terms for you.

Why Your Income Matters as Much as Your Deposit

Even with a large deposit you still need to pass affordability checks.

Lenders look at:

Your income

Your regular outgoings

Any debts or credit commitments

Your credit history

If your income does not support the mortgage repayments the lender may ask you to borrow less. That can increase the deposit you need to make up the difference.

This is why deposit and income always work together.

Do You Need a Bigger Deposit If You Are Self Employed?

Self employed buyers often face slightly stricter checks but not necessarily higher deposit requirements.

Most lenders will still accept:

5 percent to 10 percent deposits

However they will usually want:

At least two years of accounts

Stable or growing income

Clear financial records

If income is irregular some lenders may prefer a lower loan to value which can mean a higher deposit.

Buying as a Home Mover

If you already own a property your deposit often comes from equity in your existing home.

For example:

Your current home sells for £300,000

Your mortgage balance is £180,000

Your equity is £120,000

That £120,000 can form the deposit for your next purchase.

Home movers often put down 15 percent or more without realising it because equity builds over time.

Buying With a Partner

Buying jointly can reduce the deposit pressure.

Two incomes can:

Increase borrowing capacity

Reduce the need for a larger deposit

However the deposit is still based on the purchase price not on how many people are buying.

Joint buyers often find it easier to reach 10 percent or more because they are saving together.

Can a Deposit Be Gifted?

Yes a deposit can usually be gifted by family.

This is extremely common in the UK.

Lenders typically allow:

Parents or grandparents to gift deposits

The money to be non repayable

You will usually need a signed declaration confirming that the gift is not a loan and that the giver has no ownership interest in the property.

Gifted deposits do not reduce how much deposit you need but they help you reach it sooner.

Can You Use a Loan as a Deposit?

In most cases no.

Lenders do not usually allow:

Personal loans

Credit cards

Payday loans

to be used as deposits.

This is because borrowing your deposit increases risk and affects affordability.

Some specialist lenders may consider complex arrangements but for most buyers the deposit must come from savings or gifts.

Government Schemes and Deposits

There are schemes designed to help buyers with smaller deposits.

These include:

Shared ownership which often requires 5 percent of the share

First Homes which offers discounted purchase prices

These schemes reduce the deposit required but come with conditions and long term considerations.

Buy to Let Deposit Requirements

Buy to let mortgages usually require larger deposits.

Most buy to let lenders expect:

At least 20 percent

More commonly 25 percent

This is because rental properties carry different risks and are assessed differently to residential homes.

First time landlords often underestimate this difference.

Does Credit History Affect Deposit Size?

Yes it can.

If you have:

Missed payments

Defaults

County Court Judgments

some lenders may:

Require a higher deposit

Offer higher interest rates

Restrict product choice

A clean credit history gives you access to lower deposit options.

Extra Costs Beyond the Deposit

It is important not to confuse the deposit with the total cash needed.

You will also need money for:

Solicitor fees

Surveys and valuations

Mortgage arrangement fees

Stamp duty if applicable

Moving costs

Many buyers focus on the deposit and forget these additional expenses which can add several thousand pounds.

What Happens If the Property Is Down Valued?

Sometimes a lender values the property lower than the agreed purchase price.

If that happens:

The mortgage is based on the lower value

You may need to increase your deposit

Or renegotiate the purchase price

This is another reason having a small buffer beyond the minimum deposit is sensible.

Is a Bigger Deposit Always Better?

A bigger deposit usually helps but it is not always the right answer.

Putting all your savings into a deposit can leave you with no emergency fund. Lenders do not require you to use every pound you have.

The right deposit is one that balances:

Good mortgage terms

Affordable monthly payments

Financial security after completion

Common Misunderstandings About Deposits

Many people believe you always need 10 percent which is not true. Others think a 5 percent deposit guarantees approval which it does not.

Some assume first time buyers get special treatment automatically while others think deposits can come from anywhere.

Most confusion comes from not understanding that deposit rules depend on both lender policy and individual circumstances.

My Professional View

In my professional experience most buyers need between 5 and 10 percent to buy a home in the UK. Buyers with stronger finances often put down more because it makes the mortgage cheaper and easier rather than because it is required.

The biggest mistake is focusing only on the minimum. Planning for a realistic deposit and the extra costs leads to a much smoother buying process.

Final Thoughts

So how much deposit do you need for a house in the UK?

For most buyers the answer is between 5 and 10 percent of the purchase price. Some will need more depending on income credit history or property type while others can buy with less through specific schemes.

The right deposit is not just about getting a mortgage approved. It is about setting yourself up to buy confidently without stretching your finances too far.

Speaking to a whole of market mortgage adviser early on is one of the best ways to understand exactly what deposit you will need based on your own situation and goals.
