If you’ve walked away from a car finance deal thinking “hang on… that wasn’t explained properly”, you’re not alone. Car finance can involve 3 different parties, and the complaint route depends on who did what.

This guide shows you how to work out whether you should complain to the dealer, lender, or broker, what timelines apply in the UK, and how to move things forward without getting passed from pillar to post.

Dealer, lender, broker: who’s responsible for what?

Most PCP and HP deals involve a chain:

The dealer (the showroom / car seller)

The dealer is the person you sat with. They’re the ones who typically:

• talk you through the monthly payment and deposit

• handle the sales conversation and paperwork signing

• explain (or fail to explain) key terms like mileage, balloon payments, and early settlement

You may want to complain about the dealer if you feel you were:

• pressured into signing quickly

• steered to focus only on the monthly payment

• not clearly told the total repayable, APR, or final payment

• told something verbally that doesn’t match the paperwork

The lender (the finance company)

The lender is the company that provided the credit agreement. They’re usually responsible for:

• approving the finance

• assessing affordability and eligibility

• overseeing how the finance was arranged under regulated rules

• issuing a formal complaint “final response”

In practice, if your complaint is about how the finance was set up (not just the car sale itself), the lender is often the key decision-maker.

The broker (the middleman who arranged the finance)

A broker might be involved if you used:

• a car finance website

• a third-party credit intermediary

• a service that compared lenders on your behalf

Some dealers also act as a “credit broker”, which is why the wording can be confusing. If a broker was involved, they may be responsible where:

• key costs or fees weren’t made clear

• the product didn’t fit your needs

• they pushed you towards a particular lender without being transparent

What can you complain about?

Most car finance complaints fall into a few common themes:

• Affordability concerns: the payments were clearly not sustainable based on your income and normal outgoings at the time.

• Key terms not properly explained: mileage limits and excess charges, balloon payments, voluntary termination, early settlement, or what happens at the end of PCP.

• Unclear total cost: you were shown a monthly figure but not properly walked through the total repayable and APR in a way you could reasonably understand.

• Commission-related unfairness: you weren’t told how intermediaries were paid, and you suspect it may have influenced the interest rate or the deal you were offered.

The Financial Conduct Authority has estimated that a very large number of UK agreements could be affected by commission-related issues in motor finance, covering agreements dating back to 2007. That’s why it’s worth checking even if the deal felt “normal” at the time.

The complaint process (UK): step-by-step

Step 1: Get your facts together (keep it simple)

You don’t need a perfect bundle of evidence. Start with:

• the finance agreement (PCP/HP paperwork, if you have it)

• any emails, texts, or screenshots from the sale

• a short timeline of what you remember being told

• what you were earning and roughly spending at the time (if affordability is the issue)

If you’ve lost paperwork, don’t panic — you can still complain and ask the lender for information they hold about your agreement.

Step 2: Complain to the right party (often the lender first)

If your complaint is about the finance (affordability, unfair terms, commission-related issues), complain to the lender first. That usually gives you the cleanest route to a formal outcome.

You can also complain to:

• the dealer (especially if the sales conversation was misleading), and/or

• the broker (if a broker sourced the finance and you think the arrangement process was unfair)

The important bit is: don’t let anyone “bounce” you endlessly. If the problem is how the finance was arranged, the lender should still deal with your complaint properly.

Step 3: Know the timeline for a final response

Normally, regulated firms have up to 8 weeks to issue a final response to a complaint. If they don’t respond in time (or you disagree with the result), you may be able to escalate.

Motor finance commission complaints have had some special timing rules in the UK. The FCA introduced temporary complaint-handling measures for certain motor finance commission complaints (covering specific periods), and these rules affected how long firms had to respond and how long you had to take things further. The practical takeaway is simple: dates matter. If your complaint sits in that commission-complaints window, you may have longer to escalate than the usual 6 months from the final response letter.

If you’ve already received a final response and you’re unsure what deadline applies, it’s worth acting quickly rather than waiting.

Step 4: Escalate if you’re not happy with the outcome

If the lender/broker is regulated and you receive a final response you don’t agree with, you may be able to take it to the Financial Ombudsman Service. In many cases, you’ll usually need to refer your complaint within 6 months of the final response letter — but for certain car finance commission complaints, the window can be longer depending on exactly when the final response was issued.

When to complain to the dealer vs lender vs broker (a quick cheat sheet)

Complaint to the dealer if…

• you were pressured into signing

• the salesperson told you something that wasn’t true

• major PCP/HP terms weren’t properly explained (mileage, balloon, end options)

• you feel the sale was misleading or rushed

Complaint to the broker if…

• they arranged the finance and didn’t clearly explain costs or terms

• they pushed you into a product that didn’t fit your needs

• you feel they weren’t transparent about how the deal was sourced

Complaint to the lender if…

• affordability checks were weak or didn’t reflect your situation

• you suspect the deal was unfair due to how it was structured

• you want a formal final response and a clear escalation route

• commission-related concerns are part of your complaint

What outcomes can you expect?

If a complaint is upheld, outcomes can include:

• a refund of some interest and charges

• compensation for unfairness

• adjustments that put you back in the position you’d likely have been in if things had been handled properly

There’s no single “standard” payout — it depends on your agreement, your circumstances, and what went wrong — but successful claims can range from £100s to £1,000s, and in some cases more.

FAQs

Can you complain if you took the finance out years ago?

Often, yes — but time limits can apply depending on the type of complaint and when you realised (or should reasonably have realised) there was an issue. If you’re unsure, it’s usually better to start the process rather than delay.

Will complaining affect your credit score?

Making a complaint itself shouldn’t impact your credit score. If you’re currently paying the agreement, keep paying as normal while the complaint is assessed unless you’ve received separate advice to do otherwise.

What if the dealer has closed down?

You can usually still complain to the lender, because the finance agreement is with them.

What if you don’t know who the lender was?

Your direct debit reference, old emails, or the agreement paperwork normally shows the lender. If you can’t find it, start anyway — you can still get help identifying the agreement.

Do you have to complain about yourself?

You can complain to yourself for free. If you’d rather not deal with the paperwork, follow-ups, and back-and-forth, you can use a specialist to handle it for you.

Is your data safe if you start a claim online?

Claim First sets out how it handles personal data in its Privacy Policy, and the website terms are covered in the Terms & Conditions.
