Ashley Cocker

Partner | Medical Negligence Solicitor

With over a decade of experience in medical negligence law, I support clients through some of the most complex and sensitive cases involving serious injury, misdiagnosis, and avoidable harm. As a Partner at Horsley Law, I lead on a wide range of clinical negligence matters, including:

  • GP & Doctor Negligence
  • Surgical errors
  • Birth Injuries
  • Hospital-Acquired Infections
  • Fatal cases and inquests
  • Delayed or failure to diagnose serious conditions

I have acted for clients across the UK and overseas, including time as Crown Counsel (Civil) with the St Helena Government, offering insight into public healthcare systems and international legal practice. Before joining Horsley Law, I worked at nationally recognised firms including Irwin Mitchell and Browne Jacobson, gaining valuable experience in high-value and complex litigation.
As a dedicated professional, I’m known for being easy to work with, meticulous in my approach, and clear in my communication. I build lasting relationships through trust and collaboration.

Whether supporting clients or partnering with medical experts, I bring a calm, solutions-focused mindset that ensures smooth and effective outcomes. Working hard to make the legal process clear and straightforward, so our clients feel informed, supported, and reassured—especially during emotionally challenging times.

Whether you or a loved one have experienced poor medical care, delayed diagnosis or life-changing injury, I’m here to help you secure the answers, accountability and compensation you deserve.

ashley cockerHelping clients get answers, accountability and fair compensation

I specialise in high-value, complex cases involving serious injury, diagnostic failures and fatal incidents. I work closely with clients, experts and professionals to achieve the best outcomes—whether that’s compensation, answers or accountability.
Key areas of expertise:

  • Orthopaedic injuries & surgical errors
  • Delayed cancer diagnosis
  • Brain and spinal injuries
  • Fatalities and inquests
  • Missed or incorrect diagnoses

My background includes roles at leading national firms such as Irwin Mitchell, Browne Jacobson, and Flint Bishop and also spent over three years serving as Crown Counsel (Civil) for the St Helena Government—giving me wide-ranging insight into healthcare systems, litigation risk management and public sector accountability.

Whether I’m advising a client or collaborating with a referring solicitor, expert witness or medico-legal consultant, I value clarity, trust and shared purpose.
Clients and experts often describe me as clear, thorough, and approachable. I take pride in being professional but personal—guiding clients through complex legal processes with sensitivity, strategy and care.

Let’s connect if our work aligns, or if you’d like to discuss a case, collaboration or referral as I’m always open to building new relationships with professionals, experts, and clients needing support in medical negligence or serious injury cases.
