Can you get a mortgage with bad credit if you have a large deposit?

A bad credit history can make buying a home feel out of reach. However, it doesn’t automatically rule you out of getting a mortgage—especially if you can put down a larger deposit.

When you have adverse credit, lenders focus heavily on risk. A bigger deposit can reduce that risk by lowering the amount you need to borrow, which may improve your overall mortgage options.

This guide explains how lenders tend to view bad credit, how a large deposit can affect affordability and loan-to-value (LTV), and what you can do to strengthen your application.

How a large deposit can improve your chances with bad credit

Mortgage lenders assess applications using a combination of affordability and risk. With adverse credit, the “risk” part is often the hardest to overcome.

A larger deposit can help in several ways:

• Lower LTV (loan-to-value): The more you put down, the smaller the loan. A lower LTV can make you a less risky borrower.
• More protection for the lender: If house prices fall, a smaller loan relative to the property value can reduce the lender’s exposure.
• More flexibility on product selection: Some lenders may be more willing to consider applicants with credit issues when the deposit reduces their risk.

In practice, the deposit you can offer may influence which lenders consider you and how competitive the mortgage terms can be.

What “bad credit” means to mortgage lenders

Lenders usually don’t just look at a credit score. They look at the type of credit issue, how recent it is, and how your finances have behaved over time.

Common credit markers include:

• Missed or late payments
• County Court Judgments (CCJs)
• Defaults
• Debt management plans
• Individual Voluntary Arrangements (IVAs)
• Bankruptcy

Even if two borrowers have the same “bad credit” label, the details can lead to very different outcomes.

Why timing and stability matter

Many lenders place weight on whether the issue is:

• Recent vs. historic
• Resolved vs. ongoing
• Supported by a stable pattern of payments since

A larger deposit can help, but lenders will still want to see that your current income and spending are manageable.

Specialist lenders and why they may be more suitable

High-street lenders often have strict criteria. Specialist lenders may be more accustomed to assessing applications with adverse credit.

That doesn’t mean every specialist lender will accept every credit history, but it can mean there’s often a wider range of approaches to underwriting.

When you have a large deposit, it can be especially important to match your circumstances to the lender type that is most likely to consider your application.

How much deposit do you typically need?

There isn’t a single deposit figure that guarantees acceptance, because each lender has its own LTV limits and affordability checks.

However, as a general rule, where there is adverse credit, lenders often expect a higher deposit than they would for a standard application.

Some borrowers aim for:

• Around 15–20%: may be a starting point for some adverse-credit scenarios
• 25%+: can further reduce LTV and may broaden options
• 30%–40%: can make a significant difference to risk for certain cases

These are not guarantees. The key point is that a larger deposit can improve your position, but it works alongside affordability, property value, and the specific credit history.

Will you pay higher interest rates?

Often, yes. Mortgage pricing is influenced by perceived risk, and adverse credit can lead to higher interest rates.

That said, a larger deposit can sometimes help offset the risk element by reducing LTV. This may improve the range of products you can access.

It’s also worth looking beyond the headline interest rate. Total costs can be affected by:

• Fees (where applicable)
• The term of the mortgage
• Whether the product is fixed or variable

How to strengthen your application before you apply

Before submitting an application, it’s worth taking steps that can improve how lenders view your credit file and overall reliability.

Check your credit report for accuracy

Errors happen. Review your file for issues such as:

• Accounts that don’t belong to you
• Incorrect payment statuses
• Outdated information

You can also use soft searches to understand what lenders may see.

Keep credit utilisation under control

If you have credit cards or revolving credit, try to keep balances relatively low compared to your limits. Many lenders prefer to see utilisation that isn’t excessive.

Avoid multiple applications in a short period

Repeated applications can create additional searches on your file. Space applications out where possible and ensure you’re targeting the right lender approach.

Make sure your current payments are consistently on time

Even if you can’t change past events, lenders will look closely at your current behaviour. A steady pattern of on-time payments can support your application.

Consider an explanation where appropriate

In some cases, providing context for a credit impairment can help. The goal is clarity—what happened, what you did to address it, and what your finances look like now.

Documentation lenders may expect

A mortgage application with adverse credit typically still requires the same core documents as any standard application, plus anything that helps explain or evidence your situation.

Commonly requested items include:

• Proof of income (e.g., payslips or tax information)
• Identification
• Evidence of deposit funds
• Bank statements
• Information relating to the credit issue (for example, CCJ details or discharge paperwork)

What’s required can vary by lender and the nature of the credit history.

Frequently asked questions

Can I get a mortgage with bad credit and no deposit?

In most situations, it’s extremely difficult. A deposit is often used to reduce lender risk, and adverse credit can make that requirement more important.

If you don’t have a deposit, it may be worth exploring alternative routes such as family-assisted options or other structures—depending on your circumstances.

Is there a cooling-off period for fixed-rate mortgages?

Fixed-rate mortgages generally don’t have a universal “cooling-off” period in the way some other products do. You’ll usually be tied to the mortgage terms once it completes, and early repayment may be subject to charges.

Does having a large deposit automatically mean you’ll be accepted?

No. A large deposit can improve your position, but lenders still assess affordability and the details of your credit history. Acceptance depends on the full picture.

Why a broker can help when credit is less than perfect

When your credit isn’t ideal, the process can be more complex than a standard application. Different lenders weigh credit issues differently, and the most suitable option may not be obvious.

A broker can help by:

• Understanding how your deposit and credit history may be viewed
• Identifying lender types that are more likely to consider your circumstances
• Helping you avoid unnecessary applications that could create further credit searches
• Supporting you with the paperwork and presentation of your case

Summary

A large deposit can be a powerful factor when you have bad credit. By reducing LTV and lender risk, it may improve the range of mortgage options available.

However, lenders will still look at the type of credit issue, how recent it is, and whether your current finances show stability. Strengthening your credit file, preparing documentation, and targeting the right lender approach can make a meaningful difference to your outcome.
