What credit score do I need for car finance?

Your credit score plays a significant role in car finance — it affects whether lenders approve your application, how much they're willing to lend, and crucially, the interest rate you're offered. A stronger credit score typically means a lower APR and a cheaper deal overall. But the system is more confusing than it needs to be, partly because there are three different credit reference agencies in the UK, each with their own scoring scale, and partly because lenders don't publish the exact scores they require.

This guide explains how credit scores work in the context of car finance, what the three agencies' ranges mean in practice, how your score affects the APR you're offered, and what you can do to improve your position before applying.

The three UK credit reference agencies — and why they all give you different scores

In the UK, there are three main credit reference agencies: Experian, Equifax, and TransUnion. Each one collects financial data about you — payment history, credit accounts, electoral roll registration, court judgments, and more — and uses it to calculate a credit score. Lenders typically check one, two, or all three when you apply for finance.

The important thing to understand is that each agency uses a different scoring scale, so a score of 700 means something very different depending on which agency generated it. A score of 700 with Experian (which scores up to 999) is in the "poor" band. A score of 700 with Equifax (which scores up to 700) is a perfect score. And a score of 700 with TransUnion (which scores up to 710) is near-perfect.

This is why comparing your scores across agencies in raw numbers is meaningless — you need to understand where each score sits within its own range.

What score do I need for car finance?

There is no single universal minimum credit score for car finance. Every lender sets its own criteria, and those criteria aren't published. A lender might approve someone with a "fair" credit score but decline someone with a "good" score if other factors — income, employment history, existing debt — paint a less reassuring picture.

That said, the general relationship between credit score band and finance availability is consistent across the industry:

Excellent / Very good credit. You'll typically have access to the widest range of lenders and be offered the most competitive interest rates. Most mainstream car finance products will be available to you, and lenders will compete for your business.

Good credit. You'll be approved by most mainstream lenders. The rates offered may be slightly higher than those available to applicants with excellent credit, but the difference is often modest.

Fair credit. Approval is generally still achievable, but the pool of willing lenders narrows and interest rates will be higher. Some lenders who specialise in this credit tier may offer suitable products.

Poor credit. Mainstream lenders are unlikely to approve. Specialist lenders exist for this market, but rates are significantly higher. A larger deposit or a guarantor can improve the position.

Very poor / bad credit. Approval is difficult without a specialist lender, guarantor, or substantial deposit. This is also the territory where CCJs, defaults, or bankruptcy will appear on your file.

How does my credit score affect the APR I'm offered?

This is where the score has a direct financial impact. Car finance in the UK is priced by risk — lenders charge higher interest rates to borrowers they consider higher risk, and lower rates to borrowers they consider lower risk. Your credit score is one of the primary inputs into that risk assessment.

The difference between a competitive APR and a high-risk APR on a car finance agreement can be substantial. On a £12,000 car financed over four years, the difference between 8.9% APR and 24.9% APR amounts to thousands of pounds extra in interest over the term. Improving your credit score before applying — even moving from "fair" to "good" — can translate into meaningful savings over the life of the agreement.

Lenders are required to offer their advertised representative APR to at least 51% of approved customers. If your credit profile means you fall outside that 51%, the lender can legally offer you a higher rate. This is why the rate you're actually offered when you apply may differ from the rate advertised.

Hard searches vs soft searches — and why this matters

When you apply for car finance, lenders typically perform a credit search to assess your application. There are two types:

A hard search leaves a visible mark on your credit file that other lenders can see. Multiple hard searches in a short period can lower your credit score and may signal to lenders that you've been applying for credit in multiple places — which can itself be seen as a risk signal. Hard searches typically remain on your file for 12 months.

A soft search checks your credit information but does not leave a visible mark on your file. It has no impact on your credit score. Other lenders cannot see it.

This distinction matters enormously for car finance shopping. If you apply formally to multiple finance providers in quick succession, each hard search compounds the impact on your score. The smart approach is to use eligibility checkers — tools that use a soft search to give you an indication of your likelihood of approval and the rates you might be offered — before making any formal applications.

Carsa's finance eligibility check at carsa.co.uk/car-finance uses a soft search, so checking whether you're likely to be approved will not affect your credit score in any way.
