Kate Sullivan
Introduction
Kate Sullivan is a former registered mental health nurse who worked on a low secure rehabilitation ward in the United Kingdom. In April 2026, a Nursing and Midwifery Council (NMC) fitness to practise panel struck her name off the nursing register after finding that she had an undeclared personal and sexual relationship with a colleague, including sexual intercourse in the workplace, and had breached professional boundaries with a vulnerable patient. The panel found the proved facts amounted to misconduct and that her fitness to practise is currently impaired.
Background Information
Sullivan was a registered mental health nurse, a title regulated in the United Kingdom by the NMC, and worked on a low secure rehabilitation ward, a setting that treats patients who are detained or otherwise vulnerable and who typically require structured, supervised care. The NMC case against her carried the reference 16G0174W. Public records of her training, earlier employment and personal history are limited; the determination is the principal published account of her career. The substantive hearing opened on 5 January 2026 and closed on 10 April 2026, and Miss Sullivan did not attend the hearing or engage with the proceedings.
The Controversy or Incident That Led to Their Cancellation
Adjudicated vs. alleged. The NMC panel found the listed charges proved after hearing evidence; charges 7, 8b, 8d, 8e and 10c were found not proved and the NMC offered no evidence on charge 9d, so any conduct connected to those remains an unproven allegation. Sullivan was never criminally charged. The findings are regulatory adjudications, not criminal convictions.
The charges considered by the panel arose from her conduct on the low secure rehabilitation ward. The panel found proved that from on or after October 2020 Sullivan was in a personal relationship with a colleague and failed to disclose that relationship to her employer, and that she engaged in sexual intercourse with the colleague in the workplace on three specified dates in 2021 and 2022. It further found that on more than one occasion she breached professional boundaries with a patient referred to as Patient B, and that on 22 March 2022 she left the ward with the colleague to take Patient B off the ward for bloods, leaving insufficient male staffing and without managerial support.
The panel also found proved clinical charges concerning a patient referred to as Patient A: that on 2 May 2022 Sullivan refused to examine Patient A, and that between 6 and 9 May 2022 she refused tobacco or tobacco alternatives to Patient A. On the leadership side, it found she demonstrated poor leadership, including manipulating the rota and going on breaks with the colleague, arrangements the panel later described as manipulated staffing to spend time with him. It found she failed to complete Datix reports, the NHS incident-recording system, for serious incidents in which patients had sexually assaulted staff. Finally, it found that on multiple occasions she behaved unprofessionally toward colleagues, including using offensive language about them and breaching their confidentiality.
On the facts, the panel found charges 1a, 1b, 2a, 2b, 2c, 3a, 3b, 3c, 4a, 4b, 5, 6, 8a, 8c, 8f, 9a, 9b, 9c, 10a, 10b and 10d proved. It found charges 7, 8b, 8d, 8e and 10c not proved, and the NMC offered no evidence on charge 9d. The panel concluded that the proved facts amounted to misconduct, comprising a serious and wide-ranging pattern of behaviour spanning clinical failures, boundary violations, leadership failings, and unprofessional conduct toward colleagues.
Public Reaction and Consequences
The determination records the panel’s assessment rather than any wider public debate. On mitigation, the panel noted Sullivan’s previous good character and history, including private health-related context, but did not regard those matters as carrying material mitigating weight given the breadth and seriousness of the misconduct found proved. On aggravation, it cited her abuse of a position of trust, her very limited insight into her failings, a pattern of misconduct over a period of time, conduct which put vulnerable patients at risk of suffering harm, conduct which put colleagues at risk of harm, and the way she manipulated circumstances and staffing arrangements in order to pursue her own objectives.
The panel determined that Sullivan’s fitness to practise is currently impaired on grounds of both public protection and the public interest, finding deep-seated attitudinal concerns, very limited insight and a real risk of repetition. For those reasons it imposed the most severe sanction available, a striking-off order removing her name from the register, with the decision dated 10 April 2026.
Current Status
As of the decision date of 10 April 2026, Sullivan stands struck off the NMC register, meaning she is erased from it and may not work as a registered nurse in the United Kingdom. Her current registration status can be checked against the NMC’s public register. She was never criminally charged in connection with the conduct, and the findings against her are regulatory adjudications rather than criminal convictions.
Impact on Their Career/Life
Erasure ends Sullivan’s registered nursing career in the UK unless she successfully applies for restoration, a route that is discretionary and requires the NMC to be satisfied she is fit to return. A striking-off order also carries reputational consequences that follow a practitioner: the determination is publicly published and discloses her identity. The panel’s findings on insight and risk of repetition, together with her non-engagement with the hearing, weigh against any early return. Beyond the register, the determination is the only published record of the matter, and it does not report on her life afterwards.
