Can you refinance car finance to get a better deal?

If you took out car finance 12, 18 or 24 months ago when your credit score was lower or your circumstances were less stable, there's a reasonable chance you're paying a higher APR than you'd be offered if you applied today. That's a frustrating position to be in — locked into a rate that made sense at the time but no longer reflects your financial profile.

The good news is that you're not necessarily stuck. Refinancing car finance — replacing your existing agreement with a new one on better terms — is a legitimate option for many UK borrowers. But it comes with conditions, costs, and genuine alternatives worth understanding before you act. Here's a complete guide.

What does refinancing car finance actually mean?

Refinancing car finance means settling your existing finance agreement early and replacing it with a new one, usually from a different lender, at a lower APR or on different terms. The process involves:

Requesting your settlement figure from your current lender — the amount required to pay off your existing agreement in full. Using the new finance to pay off that settlement figure. Starting fresh with the new lender at the new rate and terms.

The goal is usually one of three things: a lower monthly payment, a lower total cost of credit over the remaining term, or both. Whether refinancing achieves that depends on the numbers specific to your situation — particularly the settlement figure, the new APR, any early repayment charges, and the remaining term.

What is a car finance settlement figure?

A settlement figure is the total amount you need to pay your current lender to close your finance agreement early. It is not the same as the amount you still owe in remaining monthly payments.

Under the Consumer Credit Act 1974, you have a statutory right to request a settlement figure at any time (Section 94). Your lender is legally required to provide it within 12 working days. The figure includes:

The outstanding capital balance (the remaining amount you borrowed). Accrued interest to the settlement date. A statutory rebate of future interest you would have paid — meaning you don't pay all the interest for the full remaining term, just a proportion of it. Any early repayment charge, if your agreement includes one (typically up to 58 days' interest on agreements of more than 12 months remaining).

The settlement figure will be higher than the remaining payments you can see on your statement because it's calculated differently — using the actuarial method under the Consumer Credit (Early Settlement) Regulations 2004. The simplest approach is to contact your lender directly and request the figure in writing. Most lenders also provide it through their online portal or app.

When does refinancing make financial sense?

Refinancing makes sense when the savings from a lower APR over the remaining term outweigh the costs of exiting your current agreement and setting up a new one. It's worth considering when:

Your credit score has improved significantly since you took out the original agreement. If you were in the fair or poor credit band when you originally applied and have since moved to good or excellent, you may qualify for a materially lower rate today. The difference between a 18% APR and a 9% APR on a £10,000 balance with two years remaining is substantial — running the numbers is worthwhile.

Interest rates in the market have fallen since your agreement started. If you took out finance at a period when lender rates were high and market rates have since dropped, you may be able to secure better terms even without any change to your credit profile.

Your financial circumstances have changed and you need lower monthly payments. Refinancing over a longer term can reduce monthly payments even if the APR isn't meaningfully lower. Be aware that extending the term increases the total interest paid over the life of the agreement — lower monthly payments aren't the same as a cheaper deal overall.

You have a PCP agreement and want to switch to HP. Some buyers refinance out of a PCP deal mid-agreement to move onto a hire purchase structure, avoiding the balloon payment at the end and working towards outright ownership more simply.

When doesn't refinancing make sense?

Refinancing is not always the right move, and it's worth being clear about the scenarios where it isn't worth pursuing.

If your current agreement has significant early repayment charges relative to the interest saving, the maths may not work in your favour — particularly on agreements with less than 12 months remaining, where the future interest saving is small.

If your credit score hasn't improved since your original application, the new lender will likely offer a similar or higher rate, making the exercise pointless and leaving you with a hard search on your credit file for no benefit.

If you are more than halfway through your PCP or HP agreement, the interest front-loading on most car finance agreements means most of your interest has already been paid. Refinancing at this stage provides less benefit than refinancing earlier in the term.

If you are close to the threshold for voluntary termination (having paid 50% of the total amount payable on a PCP or HP agreement), it may be worth waiting to reach that threshold rather than refinancing. Voluntary termination under Section 99 of the Consumer Credit Act allows you to hand the car back and walk away with nothing further owed, which can be a better outcome than refinancing in some circumstances.

How to check whether refinancing will save you money

Before approaching any new lender, do the maths. You need three numbers:

Your current settlement figure (request it from your lender). The APR you're likely to be offered on a new agreement (use a soft search eligibility checker — this won't affect your credit score). The remaining term you want to finance over.

With those three numbers, you can calculate the total cost under your current agreement versus the total cost under a new one. The saving needs to be material enough to justify the effort and any early repayment charge on your existing deal. If the saving is modest — say, under £300 over the remaining term — the exercise may not be worth it. If it's £800 or more, it's very much worth pursuing.

Voluntary termination vs refinancing: which is better?

These are two different tools for two different situations, and it's worth understanding both before deciding.

Voluntary termination (under Section 99 of the Consumer Credit Act) allows you to return the car and end your PCP or HP agreement once you've paid 50% of the total amount payable. You walk away with no further obligation, subject to the car being in good condition with reasonable mileage. This is useful if you can no longer afford the payments, or if the car's value has fallen significantly and you'd rather return it than continue paying. It does not give you a path to a different car or different finance — it's an exit, not a restructure.

Refinancing keeps you in the car and restructures the debt. It's useful when you want to keep the vehicle but reduce the cost of the remaining finance. You're not exiting the market — you're renegotiating within it.

If you're considering voluntary termination, check whether you've reached the 50% threshold before doing anything else. Your lender can confirm the total amount payable and how much you've paid to date. It's also worth noting that voluntary termination affects your credit file — it's noted, though it isn't the same as a default or missed payment.

Part exchange as an alternative: trading in and starting fresh

For many drivers, particularly those 18–30 months into a PCP deal, there's a third option that's often overlooked: part exchanging the car and starting a completely new finance agreement on a different vehicle.

Here's how it works. The dealer pays off your settlement figure directly to your current lender. Any positive equity in the car — the difference between the car's current market value and your settlement figure — is applied as a deposit to your new agreement, reducing the amount you need to finance and therefore your monthly payments and total interest. You drive away in a different car on a new agreement at whatever rate your current credit profile qualifies you for.

This is particularly compelling if you originally bought a car that has held its value well, because positive equity effectively gives you a deposit you haven't had to save for. It's also simpler than refinancing — one conversation with one dealer, rather than managing a settlement, a new finance application, and the transfer of ownership separately.

If your car is in negative equity — worth less than the settlement figure — part exchange is still possible, but the shortfall is typically added to the new finance agreement. This increases the amount you're borrowing, which needs careful consideration.

The refinancing process: step by step

If you've decided refinancing is the right move, here's how to approach it without damaging your credit file unnecessarily.

Start by requesting your settlement figure from your current lender. Do this in writing so you have a dated record. The figure is typically valid for 28 days.

Next, check your credit score across all three agencies (Experian, Equifax, TransUnion) using the free tools available (Experian directly, ClearScore for Equifax, Credit Karma for TransUnion). Understand where you currently stand before approaching lenders.

Use soft search eligibility checkers to get an indication of the rates available to you from potential new lenders. A soft search has no impact on your credit file. Only proceed to a formal application — which triggers a hard search — once you're confident in the rate you're likely to be offered.

Compare the total cost of the new agreement (monthly payment multiplied by remaining term, plus any fees) against the total cost of your current remaining payments. Confirm the saving justifies any early repayment charge on your existing deal.

Apply formally to your preferred lender. Once approved, the new lender typically pays your settlement figure directly to your existing lender, and your new agreement begins.

What to watch out for

A few things are worth being careful about when refinancing.

Some lenders charge arrangement fees or documentation fees on new agreements. These add to the true cost and should be factored into your comparison.

Be cautious about extending the term significantly. A four-year agreement becoming a new five-year agreement from the midpoint means you're financing the car for seven years in total. Even at a lower APR, the total interest paid may be higher than simply completing your original agreement.

If your car is on a PCP, refinancing converts the deal structure. You'll need to clarify with the new lender whether the balloon payment is being rolled into the new balance or handled separately. Most refinancing on PCP deals effectively converts them to HP, which means you're committing to own the car outright at the end.

Only apply to one lender at a time. Multiple hard searches in quick succession can reduce your credit score and signal financial distress to lenders, which works against you.
