Most people who bought a car on finance a few years ago do not keep the paperwork. If you are thinking about a car finance complaint, the first obstacle is often simpler than the legal questions: you cannot remember who the lender was, or you cannot find the agreement.
That is a common position, and it can be fixed. The FCA points to three routes for identifying a lender: old bank statements, the dealer, and your credit file. If those fall short, you can ask a lender or broker for the data it holds on you under UK data protection law. This guide walks through each step in order, starting with the quickest.

Why your agreement details matter
A complaint is easier for a lender to deal with when it can match you to a specific agreement. The FCA's car finance claims page starts the complaint process with finding your lender, and its list of lenders gives contact details and a template complaint letter.
The lender's name, the vehicle, the start date and the agreement number all help. Lenders also review agreements one at a time, as Volkswagen Financial Services explains on its commission complaints page, so if you financed more than one car you may need to identify the lender for each. For the wider picture on timing, see our guide on whether to wait or complain now.
Step 1: Check the paperwork and accounts you already have
Start with what is easiest to reach. Look through:
- The original agreement and any pre-contract documents the dealer gave you.
- Emails from the dealer or lender, including settlement or completion letters.
- Bank statements showing a regular monthly payment to a finance company during the period you had the car.
- Online accounts, apps or welcome packs from the lender.
The FCA names old bank statements as a way to identify your lender. They are often the quickest route, because a monthly payment normally carries the lender's name or a close variant of it.
Watch the name on your paperwork
The name you see may be a brand or trading name rather than the legal lender. Volkswagen Financial Services, for example, lists Audi Financial Services, SEAT Financial Services and Škoda Financial Services among the trading names it covers.
If a name is unfamiliar, search for it on the FCA's list of lenders before going further.
Step 2: Ask the dealer where you bought the car
The FCA lists contacting the dealer as another way to find your lender. The dealer arranged the finance, so it may be able to confirm which lender it used. Dealerships do close, merge and change hands over the years, so this works better for recent purchases than for older ones.
Give the dealer the vehicle registration, the approximate purchase date and your full name and address at the time. That is usually what it needs to search its records.
Step 3: Check your credit file
Your credit file may list your lender. The FCA suggests the Equifax Car Finance Checker, which it says includes most car finance records back to 2007. It adds that you can also check your credit file for free through Experian and TransUnion, and the Information Commissioner's Office explains how to access your credit file for free.
The FCA says the Equifax checker covers most records, not all of them. A missing entry therefore does not prove that you had no agreement.
Step 4: Make a free data request to the lender or broker
If you know or suspect who the lender was but need the details, you can ask for the personal data it holds on you. This is called a subject access request, or SAR. According to the ICO, organisations normally have one month to reply and normally cannot charge for responding.
The ICO adds that the month starts once the organisation has what it needs from you, such as proof of identity. A complex request can be extended by up to two further months, and the organisation must tell you within the first month if it is taking longer.
Send the request to the lender's data protection team. Many lenders publish a data protection address on their privacy or complaints pages. Volkswagen Financial Services, for example, lists one on its customer concern policy page. Putting the request in writing gives you a record of the date.
Wording you can adapt
Subject: Subject access request, motor finance agreement
Dear Data Protection Team,
I am making a subject access request under UK data protection law. Please send me a copy of the personal data you hold about me relating to any motor finance agreement, including the agreement itself, the payment history and any records of commission paid to the broker or dealer.
To help you find my records, my full name is [your full name], my date of birth is [your date of birth], and my address at the time was [your address]. The vehicle was [make, model and registration, if known], bought around [month and year].
Please reply within one month.
Yours sincerely, [your name]
What if you still cannot find your agreement?
Missing paperwork does not necessarily end the process. The FCA's rules for working out compensation allow for lenders that no longer hold a payment schedule, by using a simpler calculation basis. You can also complain with the details you do have. Volkswagen Financial Services asks complainants to include as much information as they can to help it find the agreement, and that is sensible advice for any lender.
If the person who took out the finance has died
The FCA says its scheme covers agreements held by customers who have since died, so beneficiaries may be able to claim. You can complain directly to the lender, use your own details, and make clear you are acting for someone else. Include the person's name, address, date of birth and any finance details you know. The lender is likely to ask for a copy of the will or the grant of probate.
Keep a record as you go
- Save copies of every letter, email and statement in one folder, with the dates you sent or received them.
- Note which routes you tried and what each one showed. It saves repeating work later.
- Do not give bank account details or passwords to anyone unless you are certain who they are. The FCA warns that scammers pose as lenders and offer fake compensation.
