Sinead Hayes



I am a solicitor based in the Sheffield office. I undertook my training contract at Irwin Mitchell and qualified into the Medical Negligence team in September 2013.

I manage my own caseload and also assist Sarah Rowland and Anna Stacey on a wide range of cases, such as: birth injury claims, including those involving for still births and cerebral palsy injuries; fatal claims; delay in diagnosis of cancer; mental health claims and cases of surgical negligence. 

Charity and community work is also very important to me. I am a Trustee at Sheffield Mind, a charity that offers a range of services and support to people who have suffered from a mental health problem, enabling them to lead healthy and fulfilling lives. Being a Trustee enables me to play a part in maximising the quality of service that the charity provides, making sure service-users have the support, advice, guidance and skills to improve their quality of life.

I'm passionate about fundraising work. In 2012, I slept outside Sheffield Cathedral to raise money for the Archer Project, a charity that supports those affected by homelessness. Since joining Irwin Mitchell I've been involved in a number of fundraising events, including a recent fundraising walk for Macmillan Cancer Support and many cake sales in aid of Macmillan Cancer Support and Rotherham Hospice. I have also coordinated a large shoe collection for children living in orphanages in Malawi and Sri Lanka. At Christmas, I enjoy assisting with Irwin Mitchell's annual pantomime trip, in which a number of families enjoy a trip to our local theatre. 

I take an active role in supervising work placement students that come to the firm to gain work experience; I've also lectured at Sheffield Hallam University to students who are interested in law.

Notable Cases

  • Successfully secured a £132,000 settlement for an adult who had suffered from a severe pressure sore which led to a permanent chronic pain syndrome. This significantly impacted on the client’s daily lifestyle, and they struggled to return to their previous employment. 
  • Heavily involved in a case where the individual had suffered from an Erb’s Palsy injury due to a traumatic birth. This led to permanent damage and limited function in the arm and shoulder. We received an admission of liability from the Defendant NHS Trust and an award of £575,000 for the client.
  • Successfully secured a £115,000 settlement at a mediation for our client. The case involved a delay in diagnosing a heart condition which sadly wasn’t picked up until after the individual's death. The NHS Trust admitted liability and we were able to progress to mediation to reach a resolution for the family involved.
  • Heavily involved in a case in which our client had suffered from a spinal cord injury, leading to paraplegia. The case settled for a lump sum award of £1.7m and annual periodical payments. We also secured a Provisional Damages Order, entitling our client to return to Court at a later date in the event of a serious deterioration in her condition.

    Irwin Mitchell To Host Health Awareness Day In Rotherham

    “It’s often surprising to find out how many people are both unaware of the support that is on offer from charities and organisations and the difference this advice can make to their health and wellbeing. “We work with many people who have experienced life-altering physical and mental changes, often due to circumstances that were not their own making. Events like this in Rotherham allow anyone suffering from health issues to talk openly with the experts. “With local doctors and hospitals busier than ever too many of us put off visiting a health professional and neglect problems that could soon become serious. We are there to raise awareness of how to improve, not just your health, but your families and friends who make up the local community. “We’re delighted to have the support of some fantastic charities and prestigious organisations and be able to offer free health checks and advice to the general public.”
