Can I make a sepsis compensation claim?

You may be able to make a sepsis compensation claim if you, or someone you love, developed sepsis as a result of medical negligence. Sepsis is a life-threatening condition that can progress rapidly - and when it isn't identified or treated quickly enough, the consequences can be devastating and long-lasting.

A sepsis negligence claim can stem from a number of circumstances. People come to us for support when a healthcare professional failed to diagnose sepsis in time, didn’t act on warning signs, or where the right treatment was not put in place quickly enough to prevent the condition from getting worse. In some cases, sepsis may have developed following a hospital procedure or treatment, where better care could have stopped it from taking hold.

You might also be able to claim if a loved one died as a result of sepsis that was not diagnosed or treated appropriately. This is known as a wrongful death claim, and family members may be entitled to seek compensation. If you’re unsure whether your situation qualifies, it’s still worth speaking to us. We’ll listen carefully and tell you honestly whether you might have a case.

Example of a sepsis negligence claim

Imagine a patient admitted to hospital with a urinary tract infection whose deteriorating condition – including a rising heart rate and confusion – goes unaddressed for several hours. If the clinical team failed to recognise the signs of sepsis and delayed administering antibiotics and fluids, and the patient went on to develop organ damage as a result, this could form the basis of a valid sepsis compensation claim.

Covering the costs of recovery and helping you rebuild financial security.

Securing compensation after experiencing sepsis negligence is an important first step. It first acknowledges what you’ve been through and offers some validation of your experience. But it also helps make sure you have the financial support to access the treatment and care you need – both now and in the future.

A successful sepsis compensation claim may help fund:

  • Costs of ongoing medical treatment and specialist care
  • Rehabilitation and physiotherapy
  • Psychological support and counselling, including for post-sepsis syndrome
  • Adaptations to your home or specialist equipment
  • Loss of earnings, both past and future
  • Care and support costs
  • Travel and transport costs related to your recovery
Understanding the potential value

We supported Stephanie, who developed intra-abdominal sepsis after surgeons failed to notice and repair a serosal tear during her operation. We secured £50,000 in compensation, which helped her fund her recovery and gain some financial stability. But no two sepsis cases are the same. The value of a claim depends on the severity of your illness, the lasting effects on your health and independence, the impact on your ability to work, and the level of care and support you need going forward. Cases where sepsis has caused permanent organ damage, amputation, or long-term psychological harm can result in significant settlements.

Understanding interim payments

You shouldn’t have to wait until the end of your claim to get the support you need. We understand that waiting for a claim to conclude can put real financial pressure on you and your family – especially when you are dealing with ongoing care costs or are unable to work. Where possible, we will seek to secure interim payments on your behalf. These are payments made during the claims process, before the final settlement is reached, and can help cover immediate costs such as treatment, rehabilitation, or adaptations to your home.

You're not alone

We understand the challenges you might be facing.

We know from experience that the physical and emotional impact of sepsis can be severe. We also know that, after the experience you’ve been through, the idea of claiming sepsis compensation can seem incredibly stressful.

For many people though, receiving recognition for what they’ve been through – and the medical costs they’ve incurred – is an important part of the recovery process. In some cases, sepsis can sadly be fatal, so having financial support to cover the costs of an unexpected funeral can help take some of the strain away.

We’ve supported many clients in exactly this position. People come to us feeling unsure they have experienced sepsis negligence, and are sometimes worried about reliving a painful experience. They often need someone to listen carefully, explain things clearly, and take on the hard work on their behalf.

We promise to do this for you. We’ll handle every part of the claims process, keep you informed at every stage, and pursue the compensation that truly reflects the impact of what has happened to you and your family.

FAQs about sepsis compensation claims

What is sepsis?

Sepsis, sometimes called blood poisoning, is a serious and life-threatening condition that occurs when the body overreacts to an infection and begins to damage its own tissues and organs. The initial infection can be bacterial, viral, or fungal – and can start as something relatively mild, such as a chest infection or urinary tract infection. Sepsis can progress through three stages – sepsis, severe sepsis, and septic shock – and if not treated quickly, it can lead to organ failure and can be fatal.

What is the biggest concern with sepsis?

The biggest concern is that sepsis is diagnosed and treated as quickly as possible. It causes damage to tissues and organs that can lead to shock, multiple organ failure, and sometimes death. There are also serious longer-term complications, including kidney failure, gangrene requiring amputation, permanent lung damage from acute respiratory distress syndrome, and brain damage leading to memory problems or more severe symptoms. After surviving sepsis, some people also go on to experience post-sepsis syndrome, which can involve fatigue, muscle weakness, joint pain, depression, and anxiety.

What is the NHS protocol for sepsis?

Sepsis needs diagnosing and treating quickly. The UK Sepsis Trust developed the ‘Sepsis Six’ – a series of six clinical tasks, including administering oxygen, taking cultures, giving antibiotics, giving fluids, measuring lactate, and monitoring urine output – all to be carried out within one hour of a patient arriving at hospital. A failure to follow this kind of protocol promptly can be a significant factor in a sepsis negligence claim.

How long do I have to make a sepsis claim?

In most cases, you have three years from the date of the negligent treatment, or from the date you first became aware that negligence may have been involved, to start a sepsis compensation claim. There are exceptions – for example, if the person affected is a child, the three-year period does not begin until they turn 18. If the person lacks mental capacity, different rules may apply. We recommend seeking legal advice as soon as possible, as gathering evidence and building a case takes time.

What evidence is needed for a sepsis negligence claim?

Your solicitor will gather the evidence needed to support your claim on your behalf. This typically includes your medical records, test results, and clinical notes from the time of your treatment. We will instruct independent medical experts to review what happened and give their opinion on whether the care you received fell below the standard that should have been provided. You do not need to gather this evidence yourself – we will manage the process for you.

Can I claim if a loved one died from sepsis?

Yes. If a family member died as a result of sepsis that was not diagnosed or treated appropriately, you may be able to bring a claim on their behalf. This is known as a wrongful death claim. We understand how painful this situation is, and we will handle your case with the sensitivity and care it deserves. We will help you understand whether you have grounds for a claim and guide you through the process as gently as possible.

How many people are affected by sepsis in the UK each year?

In the UK, around 245,000 people are affected by sepsis each year, and at least 48,000 people lose their lives to sepsis-related illness annually – more than breast, bowel, and prostate cancer combined. Globally, sepsis claims around 11 million lives each year. These figures highlight why early diagnosis and prompt treatment are so critical – and why failures in care can have such serious consequences.

Who is most at risk of getting sepsis?

Anyone can get sepsis but those particularly at risk are: 

  • Infants and older adults. 
  • People over 75 years old. 
  • People with diabetes, weakened immune systems, or genetic disorders that affect the immune system. 
  • Individuals who have recently had a serious illness or undergone surgery. 
  • Women who have recently had a baby, miscarriage, or abortion. 

 

Other people potentially at risk include: 

 

  • Very frail individuals. 
  • People who misuse intravenous drugs or alcohol. 
  • Individuals with indwelling lines or catheters. 
  • People with cuts, burns, or operative wounds. 
  • Pregnant women or those postpartum, especially after a Caesarean section or forceps delivery.
What support is offered during my sepsis compensation claim?

From the moment you contact us, we’ll take the time to listen and understand your situation before advising on next steps. We handle every part of the legal process on your behalf, keeping you informed at every stage in plain, straightforward language. Where possible, we will seek to secure interim payments to help with immediate costs while your claim is ongoing. Our focus is on making the process as clear and manageable as possible, so you can concentrate on your recovery.

How much time do I have to claim?

It is important to seek legal advice as soon as you can because there are time limits to filing a sepsis negligence claim. 

These are typically within three years of the incident that caused the condition or from when the potential malpractice or negligence was discovered . 

There are some exceptions, for example if a case involves a child or a person who lacks mental capacity.
