What Is a Diesel Claim?
In the wake of the VW dieselgate scandal, other car manufacturers are being investigated. A diesel claim looks at whether car makers have been lowering the emissions of their vehicles to cheat tests. This is either through the use of defeat devices, software or other means. Even the best diesel claim company is seeing if every manufacturer is implicated.
The Best Diesel Claim Companies
Based on the number of claimants, manufacturers and customer reviews, we’ve listed the following manufacturers so you can decide which is the best diesel claim company for you.
Pogust Goodhead (Most Claimants)
Also trading as My Diesel Claim, Pogust Goodhead is the best diesel claim company based on total number of claimants. Their website specifies that they have over 2 million drivers signed up to make a diesel emissions claim, which is far more than any other company.
In 2022, the company even represented claimants in the Volkswagen emissions scandal, helping reach an out of court settlement. They are looking into a range of vehicle manufacturers to see if they are also implicated. In terms of bold claims, Pogust Goodhead is the best diesel claim company, specifying up to £10,000 for each claimant. In reality, the actual settlement will most likely be much lower than this.
Bingham Long (Most Manufacturers)
Based in Liverpool, Bingham Long is the best diesel claim company for covering the most number of manufacturers. According to Money Saving Expert, they look at as many car makers as Posust Goodhead.

These include:
Audi
BMW
Ford
Mercedes
Vauxhall
Specifically looking at vehicles between 2007 and 2018, Bingham Long is the best diesel claim company in terms of criteria. The company specifies that you can make a claim even if you’ve repaired the defective software in your vehicle. As with all other solicitors, they offer a claim on a no win, no fee basis.
Leigh Day (Lowest Charges)
In terms of fees, Leigh Day is the best diesel claim company as they only charge a maximum of 30–36%, should they win the case against a vehicle manufacturer. Having worked alongside Pogust Goodhead to jointly help VW drivers receive compensation for their diesel cars, the company is dedicated to providing rightful compensation to affected diesel drivers.
For more realistic claim amounts, Leigh Day is the best diesel claim company as they specify claimants could be entitled to up to 75% of their car’s value. Depending on your circumstances with your diesel vehicle, the company says the settlement could be from 25–100% of payments made towards the car.
Best Diesel Claim Company Based on Reviews
While it’s all well and good looking at what the companies say about themselves, it’s worth honing in on customer reviews for a more realistic measure of which is the best company for a diesel claim. Based on Trustpilot and Feefo reviews, we’ve listed the best diesel claim companies below.
Leigh Day (4.7/5)

At the time of writing, Leigh Day has a Trustpilot score of 4.7, where 89% of reviews are 5 stars. Only 4% are 1 star, but these negative reviews mainly focus on a lack of communication. However, the company always responds to these reviews and offers to put these customers in touch with the right department.
In terms of customer satisfaction, Leigh Day is the best diesel claim company based on the highest portion of satisfied customers and reviews.
Milberg London (4.6/5)
Currently, Milberg London has a Trustpilot score of 4.6, but this was previously reported to be 4.7 on Money Saving Expert. 90% of their reviews are rated 4 or 5 stars, but 6% rated the company 1 star. The majority of the low scoring reviews are concerned with miscommunication or a lack thereof. Milberg London tries to explain to its customers that the courts require surveys to be filled in that are similar to information they have already supplied.
In terms of reviews, Milberg London is the second best diesel claim company available.
Pogust Goodhead (3.1/5 and 3.6/5)
Trustpilot reviews for Pogust Goodhead are sitting at 3.1, but this is only across less than 500 reviews. Feefo has over 12,000 reviews, where the company’s rating increases to 3.6. If you search for My Diesel Claim, this goes down to 1.3 on Trustpilot. Most of the low reviews are due to long lengths of time passing before manufacturers are taken to court or for misunderstandings in communication.
The 35% of 1 star reviewers on Trustpilot would argue the best diesel claim company is not Pogust Goodhead.
Many people seem to ask if My Diesel Claim is legit.
Does It Matter Which Diesel Claim Company I Choose?

Despite issues with communication being relatively widespread across different companies, it doesn’t actually matter where you file your claim. Most manufacturers are being targeted by multiple firms, so when legal proceedings reach court, all claims will be grouped together. This means every single law firm will be working together, pooling their resources to battle your case. In this way, it doesn’t necessarily matter if you choose the best diesel claim company or the worst on the list.
The only difference it will make is the amount you’ll receive in compensation when the case is settled. Each company sets a specific amount to help cover their costs and legal fees, though the majority will be taken from the vehicle manufacturer if they lose the trial. If you’re looking for a big payout, the best diesel claim company for you will be the one that charges the least.
Am I Eligible for a Diesel Emissions Claim?
To be able to make a diesel claim, you need to meet the following criteria:
Have, or have owned, a diesel vehicle between 2009 and 2020
You bought the vehicle or leased it on finance
It was new or second-hand
The vehicle was a company car in your name
It was bought within the UK
Providing your vehicle is covered under this criteria, you can make a diesel claim. Irrespective of the best diesel claim company for you, the compensation due is about suffering from an increase in emissions and how the car was not as advertised. When the vehicle is corrected, you might not benefit from the same fuel economy, which may have put you off buying the car if you had known.
While only VW and Mercedes have gone to the courts, there’s no certainty that every car maker will face the same fate. You can read up about the evidence against different vehicle manufacturers on our website.
