A fitness to practise process runs through five broad stages: a concern is raised, it's screened, it may be formally investigated, it may reach a panel hearing, and it ends in an outcome ranging from no further action to conditions, suspension, or removal from the register. Most concerns never make it past the first two stages.

Every UK healthcare regulator, the GMC, NMC, GDC, GPhC, HCPC, GOC, GCC, and GOsC, runs a version of this same basic structure, even though the specific committee names and timelines differ slightly between them. Understanding the shape of the process, before you're ever in it, makes a genuinely stressful situation at least predictable.

How common are these concerns, really?

The GMC's own 2025 annual statistical report gives a clearer picture than most professionals expect, and it's worth knowing the real numbers rather than an anxious guess.

• 13,465 concerns about doctors were triaged by the GMC in 2025, out of 410,566 registered doctors, up 25% on 2024's 10,769, the largest year-on-year increase in 20 years.
• 90% were closed at triage, 12,146 of the 13,465, without meeting the threshold for a full investigation.
• Only 997 concerns progressed to a formal investigation that year.
• Of the cases that reached a tribunal, 160 hearings were held in 2025: 124 resulted in a finding of impairment, 48 doctors were struck off, 68 suspended, 7 given conditions, and 1 saw no further action. Of the 34 found not impaired, 11 still received a warning.

The clear takeaway: the overwhelming majority of concerns raised never come close to a hearing, let alone erasure. That doesn't make an open concern any less stressful to live through, but it's a genuinely different picture from the one most professionals imagine.

What actually triggers a concern?

A concern can come from almost anywhere: a patient complaint, a colleague's report, a criminal conviction, a self-referral, or information shared by an employer during a disciplinary process. The regulator doesn't need the concern to come from a formal complaint specifically, information from any credible source can open a case.

Not every concern relates to clinical competence. A significant share involve conduct, honesty, or health, areas that surprise professionals who assume "fitness to practise" only means clinical skill.

How does the initial screening work?

Once a concern is received, the regulator screens it to decide whether it meets the threshold for a full investigation. Many concerns are closed at this stage because they don't raise a genuine question about fitness to practise, or because they're better handled by the professional's employer directly.

If a case does proceed, you'll typically be notified in writing and asked to respond. This is usually the "investigation letter" moment many professionals search for guidance on, and it's the point where getting proper advice from your defence organisation matters most.

What happens during a formal investigation?

During this stage, the regulator gathers evidence: your response, relevant records, witness statements, and sometimes an independent expert opinion on clinical matters. This stage can take months, which is often the most difficult part psychologically, since a case can sit open for a long time before any decision is reached.

Throughout this stage, actively engaging, responding on time, seeking guidance, beginning genuine reflection on what happened, is consistently treated more favourably than silence or a purely defensive posture. This isn't about admitting fault prematurely; it's about demonstrating the kind of engagement a regulator is specifically looking for.

Does every case go to a hearing?

No. Many cases conclude with no further action, a warning, or agreed undertakings, without ever reaching a formal panel hearing. A hearing is reserved for cases where the regulator believes fitness to practise may currently be impaired and a panel needs to make that determination directly.

Where a hearing does happen, for doctors specifically, it isn't actually run by the GMC itself. The GMC investigates and presents the case, but the hearing is run by the Medical Practitioners Tribunal Service (MPTS), a separate, independent body. This separation of investigator from decision-maker was introduced following the Shipman Inquiry, specifically to ensure the body deciding a doctor's fate isn't the same one that built the case against them. Other regulators run an equivalent structure under their own committee names, the NMC's Fitness to Practise Committee, for instance, though not always with a fully separate external body.

A tribunal hearing works through three distinct stages, each with its own question and its own possible outcome: first, whether the alleged facts are proven; second, whether those facts amount to genuine impairment of fitness to practise; and third, if impairment is found, what sanction is appropriate. A professional can contest any one of these three stages without conceding the others, disputing the facts doesn't require also conceding impairment, and conceding facts doesn't require conceding they amount to impairment.

What standard of proof actually applies?

Every UK healthcare regulator applies the civil standard of proof, the balance of probabilities, not the "beyond reasonable doubt" standard used in criminal courts. In practice, this means a panel needs to be satisfied it's more likely than not that something happened, often described as a 51% threshold, considerably lower than the criminal standard many people assume applies.

This lower threshold surprises a lot of professionals, and it's worth understanding clearly rather than discovering it partway through a case. It means a regulator doesn't need to eliminate reasonable doubt to find a fact proven, only to show it's more probable than not. This is precisely why the strength and specificity of your own evidence and account matters so much, a case decided on probability, not certainty, rewards a clear, well-evidenced response far more than a purely defensive one.

What determines the outcome?

This is the part worth understanding most clearly. Panels consistently weigh insight, whether you genuinely understand what happened, your part in it, and its impact, alongside evidence of remediation, concrete, evidenced steps you've already taken to address it. A case with identical facts can produce very different outcomes depending on how convincingly these two things are demonstrated.
