When you buy a car on finance, you have two main routes. You can take the finance offered by the dealer in front of you, or you can arrange it independently online before you visit. Both have advantages. Neither is always cheaper. The answer depends on your situation.
A lot of the advice out there comes from one side or the other. This guide is written by a car money saving platform, not a broker or a dealer, so we can focus on when each option works best and how to use both to get the best rate.

Dealer finance is arranged at the dealership when you buy the car. The dealer introduces you to one or more lenders they work with. You fill in the application there, often get a decision the same day, and drive away with the car and finance sorted in one visit.
A car finance broker works independently. They compare deals from a panel of multiple lenders and find options matched to your credit profile. You apply online, get quotes, and then go to the dealer (or private seller) with your finance already arranged.
The core difference is range. A dealer typically works with a handful of lenders. A broker searches across 20 or more. More lenders means more competition, which often means a better rate for you.
| Dealer Finance | Online Broker | |
|---|---|---|
| Number of lenders | Usually 2 to 5 | Typically 20+ |
| Speed | Often same-day decision | Decision in minutes, but you arrange before visiting the dealer |
| Manufacturer promotions | Yes, including 0% APR deals on new cars | No access to manufacturer-backed rates |
| Part-exchange | Handled in one visit | You arrange the sale of your old car separately |
| Rate competitiveness | Varies. Can be competitive, can include markup | Usually competitive because lenders compete for your business |
| Bad credit options | Limited. Most dealers work with mainstream lenders only | Often better. Many brokers include specialist bad credit lenders |
| Pressure to decide | Can feel pressured. You are in the showroom, excited about the car | No pressure. You compare at home, in your own time |
| Transparency | Historically mixed. FCA reforms have improved this | Rate is set by the lender, not adjusted by the broker |
Dealer finance is not always more expensive. There are specific situations where it genuinely wins.
Manufacturer 0% or low-rate promotions. Car manufacturers sometimes subsidise the interest rate on specific new models to boost sales. These 0% or 1.9% APR deals are only available at authorised dealers and are not something a broker can access. When they are genuine (and they usually are), they are hard to beat. Check the overall price of the car though, because the discount on finance is sometimes offset by a higher sticker price or less room to negotiate.
Same-day convenience. If you want everything done in one visit, dealer finance is simpler. You pick the car, arrange the finance, and drive away. No separate applications, no waiting for funds to clear.
Part-exchange integration. If you are trading in your current car, a dealer handles the valuation, the finance settlement (if your old car is still on finance), and the deposit transfer all in one go. With a broker, you would need to arrange the sale of your old car separately.
Specific dealer-only stock. Some cars are only available at certain dealers. If the car you want is right there and the finance is competitive, there may be no benefit to going elsewhere.
For most people financing a used car, an online broker will usually find a better deal. Here is why.
More lenders, more competition. A broker compares your application across a wide panel of lenders. Each lender sees the same applicant and competes on rate. This competition is what drives the price down. A dealer with three lenders on their panel cannot offer that same level of competition.
Better for non-perfect credit. If your credit is fair or poor, a broker is usually the better route. They work with specialist lenders that most dealers do not have access to. A dealer might decline you or offer a very high rate, while a broker could find a specialist lender willing to offer something more competitive. See our bad credit car finance page for more.
No markup risk. Historically, some dealers earned higher commissions by adjusting the interest rate upward. The FCA has cracked down on this (more below), but using a broker removes the question entirely. With a broker, the rate is set by the lender based on your credit profile. The broker earns a fixed commission regardless of your rate, so they have no incentive to push it higher.
You negotiate from a position of strength. Walking into a dealership with finance already approved means you can focus on negotiating the price of the car rather than being steered towards a finance package. If the dealer offers something better, great. If not, you already have your deal sorted.
No showroom pressure. Arranging finance online, at home, in your own time means you can compare properly. There is no salesperson across the desk, no urgency to sign today, and no emotional attachment to the car in front of you clouding your judgement.
The best strategy is not to pick one or the other. It is to use both and let them compete.
Check your eligibility online first Before you visit any dealer, run a soft search eligibility check via Brumble. This shows you what rate and terms you could get from a panel of lenders, with no impact on your credit score. This is your benchmark.
Visit the dealer with your quote in hand Look at the car, test drive it, and ask what finance they can offer. Do not mention your existing quote yet. Let them present their best deal first.
Compare on the same terms Look at the APR, the total amount payable, and the monthly payment on both quotes. Make sure the deposit, term length, and finance type match so you are comparing like for like. Our guide to car finance APR explains what rates to expect.
Pick the cheaper deal If the dealer beats the broker, take their offer. If the broker is cheaper, tell the dealer you have a better rate elsewhere. Some dealers will try to match it. Either way, you win.
Most people walk into a dealer with no benchmark. They have nothing to compare the dealer's offer against, so they cannot tell whether it is competitive or not. Getting a broker quote first takes five minutes and gives you the one thing that changes the entire negotiation: a number to beat.
Until recently, some car dealers in the UK used something called discretionary commission arrangements. This meant the dealer could adjust the interest rate on your car finance upward to earn a bigger commission. The higher the rate you paid, the more the dealer earned. You would never know this had happened.
The FCA banned these arrangements in January 2021. Since then, dealers have been required to use fixed commission models, where the commission they earn does not change based on the rate you are offered. This was a significant improvement for consumers.
In 2024 and 2025, the FCA went further, investigating historical cases where drivers may have been overcharged. If you took out car finance before January 2021, you may be able to claim compensation. The outcome of the FCA's review is still developing.
What does this mean for you today? Dealer finance is fairer than it used to be. The worst practices have been banned. But the structural advantage of a broker still exists: they search more lenders, which creates more competition on your rate. The FCA reforms made dealer finance better. They did not make it the best option in every case.
Whether you are comparing a dealer quote against a broker quote, or two broker quotes against each other, here is what to look at.
| What to Check | Why It Matters |
|---|---|
| APR | The total yearly cost of borrowing, including interest and fees. Lower is cheaper. But make sure you are comparing the personal APR you have been offered, not the representative APR the lender advertises. |
| Total amount payable | The true cost of the deal from start to finish. This is the number that matters most. It includes the deposit, every monthly payment, and any balloon payment or fees. |
| Monthly payment | Important for your budget, but do not compare on this alone. A lower monthly payment can hide a longer term and more interest. |
| Term length | Make sure both quotes use the same term. A 48-month deal will always have lower monthly payments than a 36-month deal, but it costs more overall. |
| Finance type | Compare HP with HP and PCP with PCP. Comparing HP against PCP is not a like-for-like comparison because PCP has a balloon payment. |
| Fees | Check for arrangement fees, option-to-purchase fees, or early settlement charges. These all add to the total cost and are sometimes buried in the small print. |
If you are buying a used car, it is also worth running a vehicle history check before you commit. This confirms there is no outstanding finance on the car, it has not been written off, and it has not been reported stolen.

Not always. Dealers can offer manufacturer-backed promotions (like 0% APR on new cars) that brokers cannot access. But on used cars, or when there is no promotion running, a broker will often find a lower rate because they search across more lenders. The only way to know for certain is to get a quote from each and compare the total amount payable.
Since January 2021, the FCA has banned discretionary commission arrangements where dealers could adjust your interest rate to earn more. Dealers now earn fixed commissions that do not change based on the rate you pay. Before 2021, rate adjustments were common and could add hundreds or thousands of pounds to the total cost. If you took out finance before 2021, you may be able to claim compensation.
Sometimes. If you have a competing offer from a broker or bank, some dealers will try to match or beat it to keep the sale in-house. There is more room to negotiate on the price of the car than on the APR itself, but having a benchmark quote gives you leverage either way. Our guide to getting the best car finance deal covers negotiation tips.
Yes. Getting an eligibility check before visiting the dealer gives you a clear benchmark. You know what rate and terms you could get elsewhere, so you can tell whether the dealer's offer is competitive or not. A soft search via Brumble takes minutes and does not affect your credit score.
A broker is a company that compares car finance deals from a panel of multiple lenders on your behalf. They do not lend you the money themselves. Instead, they find the lender offering the best terms for your credit profile. Brokers earn a commission from the lender, not from you. Using a broker is free and does not cost you anything extra compared to going directly to the lender.
Yes. When you arrange finance via a broker, the funds are sent to the dealer you choose. You are not limited to specific dealerships. This means you can find the car you want from any dealer and pay for it with the finance you arranged independently. The dealer does not need to be involved in the finance side at all.
A bank personal loan can offer competitive rates if you have strong credit, and because it is unsecured, you own the car from day one. Dealer finance (HP or PCP) uses the car as security, which means you do not own it until the agreement ends, but it can be easier to get approved for. The best option depends on your credit score, how much you want to borrow, and whether you want the flexibility of PCP. Our guide to how car finance works compares all three.
Yes, and this is often where brokers have the biggest advantage over dealers. Brokers work with specialist lenders who focus on bad credit car finance. Most dealerships only work with mainstream lenders, so if your credit is poor, they may decline you or offer a very high rate. A broker with a wider panel is more likely to find a lender willing to work with your situation.
An eligibility check from a broker uses a soft search, which does not affect your credit score. The dealer may also offer a soft search initially. A hard search only happens when you formally apply for a specific deal. As long as you only formally apply once (with whichever option is cheaper), your credit score is only affected once.
Yes, but the broker does not handle the part-exchange directly. You would either agree a part-exchange value with the dealer you are buying from, or sell your car independently. Selling independently often gets you more money. You can get competing offers via Brumble to see what your car is worth before deciding which route to take.
