Being referred to the GMC by a colleague is a distinctly different experience from a patient complaint — and presents its own professional and personal challenges. The concerns that colleagues raise are often rooted in direct clinical observation and can be more detailed and specific than patient complaints. This guide explains how colleague referrals work and what to expect.

Can Colleagues Refer Doctors to the GMC?

Yes. Any person can refer a doctor to the GMC — including colleagues, employers, clinical supervisors, and responsible officers.

GMC Good Medical Practice imposes a positive duty on doctors to raise concerns about colleagues where patient safety is at risk.

A colleague who refers a doctor to the GMC may be fulfilling a professional obligation, not making a hostile complaint.

The GMC accepts referrals from any source and does not require the referrer to have a formal role or direct clinical relationship with the doctor concerned. The strength and specificity of the information provided affects how the GMC assesses the threshold question of whether to open a formal investigation.

Referrals from responsible officers — senior doctors with formal responsibility for revalidation and fitness to practise at NHS organisations — carry particular weight. Responsible officer referrals are typically backed by documented organisational evidence and formal processes.

What Concerns Can Colleagues Raise With the GMC?

A colleague can raise any concern that relates to a doctor's fitness to practise — including:

  • Clinical competence concerns. Persistent clinical errors, near-misses, poor clinical judgment, or a pattern of practice that falls below the required standard.
  • Health concerns. Concerns that a colleague's physical or mental health — including substance misuse — is affecting their ability to practise safely.
  • Conduct and probity concerns. Dishonesty, boundary violations, unprofessional behaviour towards colleagues or patients, financial irregularities.
  • Attitude and behaviour. Persistent bullying or harassment of colleagues, disrespectful treatment of patients, or conduct that undermines team working in ways that affect patient care.
  • Concerns about cover-up. A colleague aware that a doctor is attempting to conceal concerns, obstruct an investigation, or engage in cover-up behaviour can raise this with the GMC.

The guide to GMC referrals covers the referral process in further detail.

Whistleblowing Protections and Colleague Complaints

A colleague who raises concerns about a doctor's fitness to practise in good faith is protected from retaliation under whistleblowing legislation — specifically the Public Interest Disclosure Act 1998 and its successor provisions.

Attempting to retaliate against a colleague who has made a referral is a serious probity concern the GMC treats as an additional allegation.

A doctor under investigation who suspects a colleague has made the referral must not attempt to contact, pressure, or influence that colleague.

How the GMC Handles Colleague-Initiated Concerns

Colleague-initiated referrals are handled through the standard fitness to practise triage process. The GMC assesses whether the concerns, if true, would raise a serious fitness to practise question.

If the threshold is met, a formal investigation is opened and the doctor receives a Rule 7 letter.

The GMC does not typically reveal the identity of the referrer to the doctor under investigation — though in many cases the source is apparent from the nature of the concerns raised. The doctor is given the opportunity to respond to the specific allegations, not to the referrer's identity.

Colleague referrals backed by clinical documentation, incident reports, or employer investigation findings are treated as more credible than unsupported allegations. However, the GMC investigates on its own evidence base — it does not simply adopt the referring colleague's account.

Is a Colleague Complaint Treated Differently?

Not in terms of the formal process — the investigation follows the same stages regardless of who made the referral. However, colleague referrals often differ from patient complaints in their specificity and the availability of documentary evidence.

Where a colleague referral reflects an underlying workplace dispute — personality conflicts, competition, or a professional relationship breakdown — the GMC is aware of this possibility and considers it.

However, the existence of a difficult working relationship does not make the underlying clinical concerns less valid, and the GMC assesses the evidence on its merits.

Understanding how the GMC case examiners assess the evidence helps clarify how the investigation proceeds once the file is complete.

Responding Professionally to a Colleague Complaint

The emotional dimension of a colleague referral can make it harder to respond professionally. These principles consistently produce better outcomes:

  • Do not attempt to identify or confront the referrer. Any retaliation creates an additional conduct concern.
  • Respond to the allegations, not the source. Address the specific concerns on their merits — not the motives of whoever made the referral.
  • Take the concerns seriously. Even where you believe the referral is unfair, consider whether any changes to practice are warranted.
  • Obtain legal advice early. A regulatory solicitor can help structure a response that addresses the allegations effectively.
  • Do not discuss the investigation with colleagues. Discussing an ongoing GMC investigation in the workplace risks influencing witnesses and is itself a potential conduct concern.

Frequently Asked Questions

Can a colleague refer me to the GMC?

Yes. Any person can refer a doctor to the GMC. GMC Good Medical Practice imposes a positive duty on doctors to raise concerns about colleagues where patient safety is at risk — so a colleague referral may reflect a professional obligation, not a hostile act.

Will the GMC tell me who referred me?

Not typically. The GMC does not usually reveal the identity of the referrer. The doctor responds to the specific allegations — not to the referrer's identity.

Can I contact my colleague if I think they referred me?

No. Do not attempt to contact, identify, or confront a colleague you believe has made a referral. Any such conduct creates an additional serious probity concern. Whistleblowing legislation protects colleagues who raise concerns in good faith.

What if a colleague's referral is motivated by personal animus?

The existence of a difficult working relationship does not make the underlying clinical concerns less valid. The GMC assesses the evidence on its merits. However, context about the relationship can be relevant to the doctor's Rule 7 response.

Is a responsible officer referral treated differently?

Responsible officer referrals typically carry significant weight because they are backed by documented organisational evidence and formal processes. However, the GMC conducts its own independent assessment.

What duty do doctors have to raise concerns about colleagues?

Good Medical Practice imposes a positive duty on doctors to raise concerns about colleagues where patient safety is at risk. A doctor who fails to raise genuine patient safety concerns — where they have a reasonable basis — may themselves be in breach of GMC standards.

Can I discuss a GMC investigation with my colleagues at work?

No. Discussing an ongoing investigation in the workplace risks influencing witnesses, breaching confidentiality obligations, and creating additional conduct concerns.

How does the GMC assess conflicting accounts between doctor and colleague?

The GMC gathers its own evidence base — from the complainant, clinical records, and other sources. Where accounts conflict, the case examiners assess the overall evidence including documentary records, and may appoint an independent clinical expert.

What is whistleblowing protection in a GMC context?

A colleague who raises concerns in good faith is protected from retaliation under the Public Interest Disclosure Act 1998. Retaliating against a colleague who has made a referral is a serious probity concern the GMC treats as an additional allegation.

Can a colleague complain about my behaviour towards them?

Yes. Persistent bullying, harassment, or unprofessional behaviour towards colleagues — where it affects team working and patient care — can constitute a fitness to practise concern.

What should I do immediately after receiving a GMC letter about a colleague complaint?

Contact your medical defence organisation (MDU, MPS, or MDDUS) immediately. Do not respond to the GMC until you have received advice. Do not discuss the investigation with colleagues.

Can a colleague complaint be resolved without tribunal?

Yes. Many colleague-initiated concerns are resolved at the case examiner stage — through no case to answer, agreed outcomes, or undertakings. The outcome depends on the nature of the concerns and the quality of the doctor's response.

What happens if the colleague complaint is found to be malicious?

Where a complaint is made in bad faith — for personal malice rather than genuine patient safety concern — this is relevant to the GMC's assessment. However, the threshold for establishing bad faith is high.
