What happens when a professional you trust makes a mistake that costs you dearly?
Professional negligence claims give people a way to hold professionals accountable when their failures cause serious financial loss, legal trouble, or even life-changing harm.
A solicitor missing a critical deadline, a doctor misdiagnosing an illness, or an accountant making costly tax errors, aren’t just minor oversights. They can disrupt lives, damage businesses, and leave individuals struggling with consequences they never expected to face.
Clients who have suffered due to professional negligence need legal support that cuts through complexity and gets results.
Our team at Kearney Law Group carefully assesses every case, looking at where the duty of care was breached and the impact it had.
Proving negligence isn’t just about showing a mistake was made—it requires clear evidence that the failure directly caused harm.
The right legal guidance ensures no detail is overlooked, giving clients the strongest possible claim.
Compensation can’t undo what’s happened, but it can provide financial relief and hold professionals accountable for their actions.
What is Professional Negligence?

Professional negligence happens when a professional fails to meet the level of skill, care, or diligence expected in their field, causing harm or loss to a client.
A study conducted by the UK Legal Ombudsman revealed that complaints related to professional negligence have steadily increased, particularly in the legal and financial sectors.
Many of these cases involve poor legal representation, mishandling of client funds, or incorrect tax advice that leads to serious financial penalties.
Another report by the Financial Conduct Authority (FCA) found that financial mismanagement from advisors resulted in millions of pounds in client losses, underscoring the severe consequences of professional negligence in the financial sector.
Several legal principles govern professional negligence claims, with courts requiring claimants to prove four key elements:
- Duty of Care
A professional is expected to provide services with a reasonable level of skill and diligence. The duty of care is established based on the nature of the professional-client relationship.
For example, solicitors have a legal duty to act in the best interests of their clients, while doctors must provide treatment that meets established medical standards.
- Breach of Duty
The professional’s actions—or lack thereof—fell below the expected standard in their field. This is often assessed using industry guidelines, regulatory requirements, and expert testimony from other professionals in the same field.
- Causation
The claimant must prove that the professional’s breach directly led to the harm or financial loss suffered. In legal terms, this is known as but-for causation—would the claimant have suffered the same loss if the professional had met their duty of care?
- Damages
The claimant must demonstrate that they suffered a tangible loss due to the negligence.
This can include financial losses (such as a failed investment due to bad financial advice), physical harm (such as injury resulting from medical malpractice), or reputational damage (such as a business facing lawsuits due to an architect’s design flaw).
Professional negligence claims are more than just legal disputes; they are about accountability. Clients place trust in professionals, often making life-changing decisions based on their advice.
When that trust is broken due to negligence, the impact can be severe.
Recent cases in the UK courts highlight the growing scrutiny over professional failings, with judges increasingly ruling in favour of claimants when strong evidence is presented.
Common Examples of Professional Negligence
Professional negligence can take many forms across different industries. Mistakes made by professionals often have severe consequences, ranging from financial ruin to personal injury or legal complications.
Below are some of the most common examples of professional negligence across key industries.
Legal Professionals
Solicitors and barristers play a critical role in protecting the rights of individuals and businesses.
When legal professionals fail to provide competent advice or properly handle a case, the impact can be devastating.
Some common forms of negligence in the legal field include:
- Missed Deadlines
In legal proceedings, deadlines are crucial. Missing a limitation date for filing a claim can mean losing the right to sue altogether.
Courts are strict about procedural deadlines, and failing to meet them can result in cases being thrown out.
- Incorrect Legal Advice
Clients rely on solicitors for accurate guidance. Poor advice regarding contracts, property transactions, or legal disputes can cause significant financial losses. - Mishandling Client Funds
A solicitor has a duty to manage client funds responsibly. Misuse of funds, even if unintentional, can lead to serious legal and financial consequences for the client. - Failure to Prepare a Strong Case
Solicitors are expected to conduct thorough research and present the best possible case for their clients.
A poorly prepared case can result in lost claims, unfair settlements, or wrongful convictions.
Medical Practitioners
When doctors, surgeons, or other healthcare professionals make mistakes, the consequences can be life-altering.
Medical negligence is one of the most serious forms of professional negligence and can lead to long-term physical, emotional, and financial hardship for patients.
Some common examples include:
- Misdiagnosis
A doctor failing to correctly diagnose an illness can result in delayed treatment or improper medication, leading to worsened health conditions.
According to the General Medical Council (GMC), misdiagnosis is one of the most frequent complaints made against medical professionals in the UK. - Surgical Errors
Operating on the wrong body part, leaving surgical instruments inside a patient, or performing unnecessary procedures are all considered gross negligence. - Prescribing Incorrect Medication
The wrong prescription or dosage can cause severe health complications, allergic reactions, or even death. - Failure to Obtain Informed Consent
Doctors must fully inform patients of the risks and benefits of a treatment or surgery. If a patient is not properly informed and suffers harm, it can be grounds for a negligence claim.
Accountants and Financial Advisors
Financial professionals hold a position of trust, managing money, investments, and tax affairs on behalf of their clients.
When they act negligently, individuals and businesses can suffer significant financial losses. Common examples of financial negligence include:
- Providing Inaccurate Financial Advice
Poor investment guidance or mismanagement of client funds can lead to substantial losses, particularly for businesses and individuals planning for retirement. - Failure to Detect Fraud or Accounting Irregularities
Accountants are expected to detect financial irregularities, including fraud and tax evasion. Failing to do so can lead to legal trouble and financial penalties for their clients. - Errors in Tax Filings
Incorrect tax filings can result in large fines from HM Revenue & Customs (HMRC).
This is particularly critical for businesses, where a miscalculation can lead to penalties and audits.
According to research by the Financial Conduct Authority (FCA), financial misconduct is a growing concern in the UK, with mismanagement of client funds and poor financial advice being among the top complaints.
Many claims arise from accountants or advisors failing to conduct due diligence before making financial decisions on behalf of their clients.
Architects and Engineers
Construction professionals are responsible for designing and overseeing projects that must meet safety standards and regulatory requirements.
When mistakes occur, the financial and legal repercussions can be immense.
Some common examples of negligence in the construction industry include:
- Design Flaws
An architect’s design must be structurally sound. If the design contains errors that compromise safety or function, it can lead to project delays, costly repairs, or even building failures. - Failure to Adhere to Building Regulations
Architects and engineers must ensure that buildings comply with planning permissions and safety regulations. Non-compliance can result in hefty fines and legal disputes. - Inadequate Project Management
Mismanagement of a construction project, including failure to coordinate teams or secure necessary permits, can lead to financial losses and contract disputes.
A report from the Royal Institute of British Architects (RIBA) highlighted that construction-related professional negligence cases have increased due to stricter regulations and higher expectations in project planning and execution.
A single miscalculation or oversight can lead to legal battles and substantial compensation claims.
How Do I Prove a Professional Negligence Claim?

Establishing a professional negligence claim requires demonstrating that the professional's conduct fell below the standard expected, directly causing your loss.
This often involves:
- Expert Evidence
Obtaining testimony from other professionals in the same field to establish the standard of care and how it was breached. - Documentation
Gathering all relevant records, communications, and contracts that outline the professional relationship and the services provided. - Demonstrating Loss
Providing clear evidence of the financial loss, physical harm, or other damages suffered due to the professional's breach.
What is the Time Limit for Bringing a Professional Negligence Claim?
In the UK, the standard time limit for initiating a professional negligence claim is six years from the date of the negligent act or omission.
However, if the negligence is discovered later, you may have three years from the date of discovery to bring a claim, provided this does not extend beyond 15 years from the original incident.
It's essential to seek legal advice promptly to ensure compliance with these time limits.
What Compensation Can I Expect from a Professional Negligence Claim?
The compensation, or damages, awarded in a successful professional negligence claim aims to place you in the position you would have been in had the negligence not occurred. This can include:
- Financial Losses
Reimbursement for direct financial losses incurred due to the negligence. - Loss of Opportunity
Compensation for missed opportunities or profits that would have been realized. - Non-Financial Losses
Damages for pain and suffering, emotional distress, or loss of enjoyment, particularly in medical negligence cases.
What Should I Do If I Suspect Professional Negligence?
If you believe you've been a victim of professional negligence:
- Seek Legal Advice
Consult with a solicitor experienced in professional negligence claims to assess the merits of your case. - Gather Evidence
Collect all relevant documentation, correspondence, and records related to the professional's services. - Act Promptly
Be mindful of the statutory time limits for bringing a claim to ensure your right to compensation is preserved.
