What is the cost of joining the Mercedes emission claim?

We're acting on a Conditional Fee Arrangement ('No Win, No Fee' agreement)*. This means there's no cost to join the claim and in the event the claim is lost, you'll not owe any money to us or Mercedes.

If the claim is won, a final deduction of up to 30% plus VAT and the cost of the After the Event Insurance is taken from the compensation you're awarded to cover the cost of your lawyers, funder and insurer.

Full details regarding costs and liability are provided in the information pack included in the joining process for the claim. Once you’ve registered your interest, we’ll invite you to join the Mercedes claim.

*If your claim is unsuccessful, we will not ask you to pay or contribute to our legal costs provided that you have followed the terms of the signed CFA. There may be scenarios where you are liable to meet the charges even if you do not win. An example of this would be where you stop instructing us or provide us with information that you know to be false or misleading.

How much is the Mercedes emissions claim worth?

We’re not able to comment at this stage on the amount of compensation you’ll receive if the claim is won. Compensation may be specific to the age and model of the vehicle you’re claiming for and to determine this, we’ll need to obtain expert evidence. Having said that, we do think that you may have suffered financial loss due to acquiring an affected vehicle. We expect that the losses for an average vehicle in the claim will be several thousand pounds at least.

I have registered my interest on your website. What happens next?

We’ve currently issuing thousands of claims in the High Court in England and Wales on behalf of affected Mercedes vehicle owners. Once your eligibilty has been confirmed, we’ll ask you to agree to various documentation agreeing to how the litigation will be run (called a Litigation Management Agreement) and to delegate your Authority to a Claimant Committee – a group of claimants who’ll represent the entire group of claimants in this action. The documents will also include our terms of business and fee arrangement, which will be on a ‘No Win No Fee’ basis.

At the next step, you’ll be asked to complete a questionnaire about your vehicle. For that, we suggest you have to hand you log book (V5C), your purchase/lease invoice and any finance agreements with Mercedes-Benz Financial Services. Once you’ve completed that, we’ll review your information and will contact you if we need anything further.

Once you’ve registered, we’ll keep you updated with correspondence on your claim.

Please note: you cannot sign up with more than one law firm to claim for the same vehicle. If you do so, there’s a risk that more than one firm will issue your claim at court. This is considered an abuse of the court process and may expose you to pay costs.
