Thomas O’Neill

Introduction

Thomas O’Neill is a former UK doctor, a paediatrician, whose name was erased from the medical register — struck off — by a Medical Practitioners Tribunal Service (MPTS) tribunal on 19 February 2026, following his criminal conviction for a sexual offence against a child. The tribunal, sitting at a substantive hearing that began on 18 February 2026 and ended the following day, found his fitness to practise impaired by reason of his conviction. Erasure is the most serious sanction available to the regulator: it removes a practitioner from the register entirely, meaning he is no longer permitted to practise medicine in the United Kingdom. He was identified before the tribunal by his General Medical Council (GMC) registration number, 7429073. The case was a conviction case rather than a clinical-misconduct case; what ended his career was not the quality of his care but what the criminal courts had found against him and the tribunal’s assessment of it.

Background Information

O’Neill was a doctor registered with the General Medical Council, and by specialty a paediatrician — a children’s doctor. The published determination records the conviction that brought his registration to an end: on 17 February 2025, at Edinburgh Sheriff Court, he was convicted on charges arising from conduct between 1 November 2019 and 31 May 2020. He became subject to the sex offender notification requirements under sections 80 and 82 of the Sexual Offences Act 2003 as a result of the conviction, and on 27 March 2025 he was sentenced to a Community Payback Order with an 18-month supervision period. The determination does not set out the details of his employment history or clinical career; the regulatory case, as recorded, rests on the court record and the tribunal’s evaluation of it, with the aggravating observation that the offence was connected to his role as a paediatrician.

The Controversy or Incident That Led to Their Cancellation

Adjudicated vs. alleged. His conviction at Edinburgh Sheriff Court is a matter of court record. The tribunal’s findings are regulatory determinations of the MPTS.

The conduct at the heart of the case took place between November 2019 and May 2020. O’Neill, then a person who had attained the age of 16 years or over, coerced an older child — a 15-year-old — into looking at a sexual image and communicated indecently with the child for the purposes of obtaining sexual gratification or of humiliating, distressing or alarming them. The indecent communication took the form of repeatedly communicating verbally in a sexualised manner, sending sexually explicit messages by telephone and social media, and sending intimate images to the child. He was convicted of this conduct at Edinburgh Sheriff Court on 17 February 2025, contrary to sections 33 and 34 of the Sexual Offences (Scotland) Act 2009. The offence is properly described as coercing a child to look at a sexual image and indecent communication; it is not an allegation of rape or of physical contact, and it is stated here as the courts recorded it. All three particulars of the charge were found proved on the basis of the Certificate of Conviction.

Public Reaction and Consequences

O’Neill did not attend the substantive hearing and was not represented before it. The tribunal proceeded on the papers, and the picture it recorded was unambiguous. It found that the conviction lay at the higher end of the spectrum of seriousness, noting that it concerned a sexual offence against a child and resulted in his inclusion on the sex offenders register. Among the aggravating factors it identified were premeditated behaviour, abuse of his professional position, behaviour directed to a vulnerable person, and a reckless disregard for professional standards; it also noted that the offence was connected to his role as a paediatrician, which sharpened rather than softened the concerns. On the mitigating side of the ledger it found nothing to weigh: there was no evidence of insight, remorse or remediation of any kind.

The tribunal concluded that O’Neill posed a high current and ongoing risk to all three limbs of the overarching objective — the protection of patients, the maintenance of public confidence in the profession, and the declaring and upholding of proper standards of conduct and behaviour. His fitness to practise was found impaired by reason of his conviction. Having determined that suspension would be insufficient, it directed that his name be erased from the medical register and imposed an immediate order, so that the erasure took effect at once rather than after the usual 28-day appeal period.

Current Status

O’Neill is struck off the GMC register. The tribunal’s decision of 19 February 2026, at the end of the two-day substantive hearing, took the form of erasure with an immediate order. Erasure is otherwise indefinite, though it can be reviewed after a minimum of five years. The criminal-court consequences continue to run alongside the regulatory outcome: the Community Payback Order with its 18-month supervision period, imposed at Edinburgh Sheriff Court on 27 March 2025, and the sex offender notification requirements under sections 80 and 82 of the Sexual Offences Act 2003, which attach to him by operation of law following the conviction.

Impact on Their Career/Life

The erasure ends O’Neill’s career as a doctor in the United Kingdom: removed from the register, he is no longer permitted to practise medicine, and because the tribunal judged a lesser sanction insufficient, the removal took effect immediately. The tribunal’s finding that there was no evidence of insight, remorse or remediation meant that nothing he put forward — and he put forward nothing, having neither attended nor been represented — altered the outcome. The conviction and its consequences reach well beyond the register: the Community Payback Order, the supervision period, and the notification requirements place standing obligations on him under criminal law, and the sex offenders register entry follows from the nature of the offence rather than from any regulatory decision. Any application to return to the register can be considered only after the five-year minimum review period has elapsed, and nothing in the tribunal’s assessment suggests grounds on which such an application would be likely to succeed.
