Submitting a claim sounds daunting, but it's actually quite a standardised process. Here is your roadmap to getting it done without paying a third party.

## Step 1 - Gather Your Details
You'll need:
- Your vehicle registration number.
- The name of the lender (e.g., Black Horse, Santander, MotoNovo).
- Ideally, your agreement number (though lenders can often find you without it).

## Step 2 - Use a Template
Don't just write an angry email. You need to cite the correct regulations. While many drivers search for a martin lewis car finance claim letter template or a downloadable fca template letter car finance pdf, using a static document has downsides. You have to download, format, and fill in the details manually. 

Our free web-based generator is a superior, modern alternative to a static free fca template letter car finance pdf. Instead of dealing with formatting issues or editing complex text blocks, our tool automatically builds a legally robust, customised letter citing the exact FCA rules. It prompts you for the precise information needed and outputs a clean copy ready to send.
- Use our **Car Finance Refund Letter** to generate a legally robust letter.
- It asks the lender to disclose any discretionary commission and, if present, to refund the difference.

## Step 3 - Send it Off
Email is usually best as it creates a digital paper trail. Find the "Complaints" email address for your lender (we provide a list of these).

## Step 4 - Wait for the Acknowledgement
Lenders must acknowledge your complaint promptly. If they don't reply within 8 weeks, you have the right to take your case to the Financial Ombudsman Service (FOS).

## Step 5 - The Offer
If they accept liability, they will calculate a refund. You can accept it or challenge it if you think it's too low.
