What Is Classed as a Serious Injury?

If you or a loved one have been injured in an accident that wasn't your fault, you may be entitled to seek compensation. The amount of compensation will depend on your individual circumstances, including the nature of the accident and the injuries you sustained. This often begs the question, 'What is classed as a serious injury when claiming compensation?' While there is no strict legal definition, there are several factors that can lead to an injury being treated as 'serious' under the law.

In most cases, an injury is deemed to be serious if it has a significant and lasting impact on a person’s physical or health. It may affect your ability to work, your day-to-day activities and your overall quality of life. In some cases, including those involving what are sometimes known as catastrophic injuries, the results can be life changing.

At Switalskis, our serious injury lawyers have helped many people to make a personal injury claim for a serious injury, to recover the costs of medical expenses, day-to-day care and lost earnings when dealing with the long-term consequences. Here, we outline what the court considers a serious injury based on our extensive experience handling serious injury claims, and explain how your injury affects how much compensation you could receive.

What qualifies as a serious injury?

There is no single legal definition for what qualifies as a serious injury. However, the court generally accepts that a serious injury involves a significant loss of sensory, motor or intellectual functions. These injuries often lead to a permanent disability or need long-term treatment. In many cases, a serious injury will lead to:

A long stay in hospital as an in-patient
The need for ongoing medical treatment and specialist care
A permanent change in how you live your daily life
An inability to return to the job you had before the accident

Such injuries are not just physical and may include serious harm. A serious injury can also be a severe trauma. When you make a serious injury claim, it should take into account the full extent of the harm caused, including both the physical pain and harm that follow a life-changing event.

What are the most common examples of a serious injury?

Every person and every accident is different. However, there are common examples of injuries that usually amount to a serious injury for the purposes of a claim. These include:

Traumatic brain injuries

A brain injury can happen in a car accident, a fall from height or an assault. The severity and effects of a brain injury will vary, but where it involves memory loss, changes in the injured person's personality or a loss of physical independence, the injury will be classed as a serious injury.

Spinal cord injuries

Spinal cord damage is often life changing, as it can lead to partial or full paralysis. People with spinal cord injuries may need specialist medical care, mobility aids and home adaptations, the costs of which may be recovered through compensation. Even where the accident does not result in paralysis, a spinal injury may be deemed serious for the purposes of a claim.

Amputations and loss of limbs

Losing a limb is a traumatic experience that has a lasting impact. Whether the amputation happened during the accident or was a medical necessity later, it is considered a catastrophic, life-changing injury. If you need specialist equipment or prosthetic limbs to maintain mobility, we can pursue interim payments during the claims process to support your recovery.

Severe fractures and internal injuries

Severe fractures often involve complex breaks that sometimes need multiple surgeries to correct. Where they cause internal injuries, such as damage to organs, this is deemed especially serious. They can lead to long term health problems, and our solicitors will make sure that serious injury compensation reflects the full extent of any such injuries.

Severe burns and scarring

Severe burns are incredibly painful and often lead to permanent scarring or loss of movement. The harm caused by these injuries will be a major factor in a serious injury claim, and any need for ongoing treatment will be covered by compensation.

Fatal accidents

The most serious accidents can result in someone's death. If a family member has died because of an accident, you may be able to bring a fatal accident claim for compensation . This can help cover funeral costs and provide financial support for those left behind.

How does a serious injury claim account for the lasting impact of an injury?

A serious injury does not just cause physical pain, but can have long-term and life-changing effects. It has an ongoing impact on every part of your life, all of which must be taken into account when considering compensation. You may find that you can no longer do the things you once enjoyed, and that simple tasks like getting dressed or cooking a meal will now need support. Some people need home adaptations, such as ramps or wet rooms, to move around their home safely, and these changes in daily life are a key part of any serious injury claim.

Many people with a serious injury cannot return to work. This leads to a loss of earnings which can cause a huge financial burden. Serious injury compensation is designed to help cover these losses and provide financial security for the future, whether your time off work is temporary or permanent. If you cannot return to work, we estimate the lost future earnings to ensure your compensation reflects your true losses.

When a person is seriously injured, they often rely on care from friends or family members, or require professional care. It's also possible to recover these costs when making a claim, and we'll work with medical experts to make sure that the full extent of your needs is accounted for in your compensation.

How much compensation can I claim?

The amount of compensation you may receive varies based on several factors. Compensation is split into two components: general damages that depend on the nature and severity of the injury, and special damages that account for past and financial losses. The latter can include the cost of ongoing medical treatment and rehabilitation, the impact on your ability to work and any need for specialist equipment and mobility aids.
