Diminution refers to the loss in value of a motor vehicle after it has been involved in a road traffic accident. In effect it is the depreciation in value of your car as a result of the accident, as unfortunately even if a car is fully repaired after an accident, you will find that it is worth much less when you eventually go to sell your car. You can claim for diminution to recoup the loss in value in compensation and as this is paid by the third party’s insurers, it will not affect your no claims.

What is Diminution in value?

Diminution meaning: Diminution is the loss in value of a motor vehicle after its been involved in a road traffic accident.

The loss in value could be due to the vehicle inheriting accident history which will stay on record, repairs may have been serviced to a high standard but the quality of the repairs will not make any difference to the diminution in value.


Two virtually identical vehicles are offered for sale. One’s previously incurred damages in an accident and then repaired as good as new. The other has not.

A purchaser rightly so, would not pay the same cost for an accident damaged vehicle and would expect a price reduction before purchasing the accident damaged vehicle.

It’s the reduction in price we will claim back for you.

How much is my Diminution Claim?

Each case is expertly assessed on its own merit and the value of each diminution claim. We take into account a range of factors including the vehicle age, type and extent of damage.

If the extent of damage are severe and the younger the vehicle, the more a vehicle will lose in value.

Case Study 1 – We Fought Mr Hughes Corner And Won Him Compensation In Excess of £3,000

In December 2015, we were instructed to act for a Mr D Hughes from Tunbridge Wells.

Mr Hughes was involved in a Road Traffic Accident whilst driving his 2012 plated Lotus Elise 1.6 VVT-i. His vehicle was worth approximately £30,000 at the time of the collision.

Mr Hughes was proceeding correctly on the main road when a Vauxhall Astra being driven by a third party emerged from a side road and collided with the nearside of his vehicle.

After an initial dispute on liability, we were able to obtain a full admission following the disclosure of some witness evidence that we had obtained.

Mr Hughes had instructed us to pursue a claim for personal injury and associated losses.

Mr Hughes had organised the repairs though his own motor insurers by utilising his fully comprehensive policy. When we became aware that the repair costs were almost £6,750, we explained that we felt he would benefit from making a claim for Vehicle Diminution.

We obtained our own expert engineering evidence, instructing the engineer to specifically comment on the loss of value his vehicle had sustained following the repair work, which Mr Hughes had been satisfied had been completed to a good standard.

Given the area of damage and the effect the impact had on the structure of his car, the engineer assessed the loss of value at £3,400.

With the agreement from Mr Hughes, we sent the engineers report to the third party insurers.

The insurers returned to us with their own in house engineering evidence, claiming that the claim for Diminution was nominal, and as such the insurers put forward a figure of £1,200.

We duly took instructions from Mr Hughes and he agreed with our recommendation to reject the offer and return to the third party insurers with some questions for their engineer.

The engineer acting for he third party insurers only partially answered our questions and his response was received by us with an improved offer of £2,350.

Again, with the agreement of Mr Hughes, we returned to the third party insurers to reject their offer and put them on notice of our intentions to issue Court Proceedings.

Just before we had commenced Court Proceedings, we received a telephone call from the third party insurers offering Mr Hughes the sum of £3,050.

Mr Hughes was very happy with this latest offer as he did not particularly wish for us to proceed with the matter through the Courts.

Despite the difficulties posed by the regular issues raised by the third party insurers, his whole claim was settled within six months after we received his signed Instructions.

Case Study  2 – Miss Hobbs Won Compensation Worth £1,200 From Her Diminution Case

In 2016, we were approached by Miss C Hobbs of Pontefract.

Miss Hobbs informed us that her vehicle had been hit whilst parked outside her house. The accident occurred late at night when a drunk driver smashed into the side of her vehicle and one belonging to her neighbour.

Miss Hobbs was very proud of her vehicle. She had saved up for some time to buy her first car outright.

Her car was a 15 plated Vauxhall Corsa 1.4 ecoflex with five doors. It had a low mileage and was immaculate. The car had a market value of approximately £8000.

The damage sustained came to a figure of £3175.

Miss Hobbs had the vehicle fixed to a good standard. She utilised her fully comprehensive policy she had with her motor insurers.

She contacted us as a local law firm and enquired if we could help her. Miss Hobbs felt that she should be entitled to some compensation due to her vehicle becoming less desirable on the open market.

We agreed that her vehicle would be likely to qualify for a claim for Diminution as it was fairly new, had been well maintained and had sustained a significant level of damage.

We arranged for a motor engineer to inspect her vehicle. The report stated that the claim had lost a market value of almost £1200.

Miss Hobbs agreed to this figure,and the engineers report was disclosed to the third party insurers.

The insurers acknowledged the claim, but said that they had some investigations to make.

Under three weeks later, we received a cheque for the full amount claimed.

Much to the delight of Miss Hobbs, the claim was concluded within eight weeks.

Case Study 3 – Mr Turner Wins £2,250 Compensation For Damage To His Range Rover Evoque

In July 2016, we were asked by Mr D Turner from Peterborough to represent him for a claim in respect of vehicle Diminution.

Mr Turner had parked his 2015 plated Range Rover Evoque motor vehicle in a shopping centre car park.

When he returned to his vehicle, he found that his vehicle had been hit by a young gentleman who had misjudged his own parking manoeuvre, and his attempts to park in the space next to Mr Turner’s vehicle had failed miserably. This had resulted in the third party vehicle scraping down the whole offside of Mr Turner’s vehicle.

A frustrated Mr Turner approached us and asked us whether we could help him recover the loss in value to his car he felt the accident had caused him.

We duly obliged and instructed an expert motor engineer to review copies of the repair documentation that we had obtained from Mr Turner’s motor insurers.

The cost of the repairs came to just over £6,000. With Mr Turner’s vehicle having a pre-accident value of £26,000, the engineer expected that the damage and subsequent repair work had resulted in a financial loss of £2550.

Mr Turner agreed the engineers valuation and the report was submitted to the third party insurers.

For two months, the third party insurers refused to acknowledge Mr Turner’s claim before returning to us to say that they did not believe his case would qualify for a claim for Diminution. They suggested that as the damage to his vehicle had mainly been cosmetic, he had suffered no loss.

The engineers report that we had already obtained had addressed this issue. It stated that as it had been necessary to replace and repair a number of panels to Mr Turner’s vehicle, it’s sale on value had been effected due to the prejudice it would have incurred from a potential buyer.

We were satisfied that the third party insurers were simply trying their hand and that our engineer had put forward a comprehensive and reasonable argument to justify the financial loss to Mr Turner.

We wrote to the third party insurers asking them to reconsider their position. We explained that we would have no hesitation in issuing proceedings for Mr Turner. Within three weeks, the insurers had made an offer of £2,250.

Although this was slightly lower than the figure the engineer had placed on Mr Turner’s loss, Mr Turner wished to accept the offer and confirmed his instructions to us in writing.

His case was settled within 21 days following his acceptance of their offer.

  • Oakwood were really understanding and listened. Despite me having no injury, I did have a brand new car that I thought might have been effected. I wanted to be listened to and Oakwood Solicitors were reassuring and confident that they could help me.   If you have invested a lot of money on a new car through no fault of your own you’ve had an accident but not injured yourself, if your car has been repaired it will not have the same value it had prior to the accident. You have a right to claim that money back. Approach someone who will take you seriously. I was curious and followed this up, and was really happy to know that it could be done.
