NMC Investigation Letter: First Steps for Nurses & Midwives

By CrownEthics Reviewed by qualified professionals 13 min read Updated 24 August 2026

If you've received a letter from the NMC saying a concern has been raised about your fitness to practise, the single most important thing right now is your written response to the investigation, a strong, considered response can close a case at Case Examiner stage before it ever nears a hearing. At CrownEthics, we built this guide around what actually happens at each stage, not generic reassurance.

Do this first

The first 48 hours

1

Contact your professional indemnity provider or union immediately. This is your first call, before drafting anything, whether the letter is a screening notice or a formal investigation letter.

2

Do not contact the person who raised the concern. However well-intentioned, this can be read as trying to influence the process.

3

Read the letter carefully, twice. Note which stage it represents, the specific allegation, and the response deadline.

4

Don't respond immediately from instinct. A rushed, defensive first draft is harder to walk back than a considered one submitted within the deadline.

5

Start gathering your own record of events while it's fresh, dates, context, and any relevant documentation.

How common is this, really?

The NMC now receives an average of around 590 referrals a month, according to its own published data. The overwhelming majority never come close to a hearing, only around 10% of cases that reach Case Examiners are referred on to a full Fitness to Practise Committee hearing.

~10%Proceed to a full hearing
15Months, the NMC's own end-to-end target

Worth knowing honestly: as of the NMC's own February 2026 data, 74% of cases were resolved within that 15-month target, the highest rate since December 2020, but this is a rolling performance metric, not a guarantee for any individual case. Some sources report complex cases still taking two to three years from first complaint to final hearing, so treat the 15-month figure as the NMC's own aim, not a promise.

The process, stage by stage

Every case moves through some or all of these stages. Open the one you're actually at.

1ScreeningMany close here+
The screening team checks three things: is there a written concern, is there evidence of a serious issue needing regulatory action, and is there clear evidence you're currently fit to practise. Many referrals close at this point without progressing further.
2InvestigationTarget: 25 weeks+
An investigator gathers witness statements, clinical records, employer reports, and formally invites your own written response. This response is one of the most consequential documents in the whole process.
3Case Examiners' decisionTwo examiners+
Two case examiners, one a nurse or midwife, one not, review everything and decide the outcome: no case to answer, private advice, a public warning (on the register 12 months), agreed undertakings, a consensual panel determination, or referral to a full hearing.
4Fitness to Practise Committee hearingGenerally public+
A panel of three, including a registrant and a lay member, hears the full case and decides whether fitness to practise is currently impaired, and if so, what sanction, caution, conditions, suspension, or striking-off, is proportionate.

What actually changes the outcome

Worked example

Two nurses each receive a letter about a similar medication error. Nurse A's response focuses on ward pressures at the time and disputes much of the detail. Nurse B's response acknowledges what happened, explains the specific cause, sets out the CPD and process changes already completed since, and reflects honestly on the impact. Same underlying event, materially different likely outcome, because Nurse B demonstrated exactly the insight and remediation Case Examiners are trained to weigh.

Nurse B's response didn't happen by accident, it followed a specific, learnable structure. Our Insight course teaches exactly that four-part framework Case Examiners are trained to weigh.

Recognising what went wrong is genuinely only half the task, Case Examiners are also looking for real evidence it's actually been addressed, not just a sincere-sounding explanation. That's precisely what our Remediation course helps you demonstrate.

Want the complete regulatory picture, not just this one stage? Our Fitness to Practise course covers the full process end to end, and it applies just as much to every other UK regulator as it does the NMC.

What panels are actually measuring you against

Case Examiners and Fitness to Practise Committee panels assess concerns against the NMC Code, not vague professional judgement. Knowing precisely which part of the Code your letter touches, and what it actually requires, changes how you write your response. Our NMC Ethics course maps the Code directly to real nursing and midwifery scenarios, so you can identify exactly where your case sits.

If an interim order is on the table

Where the NMC believes there's a serious, immediate risk, it can refer the matter to an Interim Orders Panel, which can suspend your registration or impose conditions while the wider investigation continues. This is precautionary, not a finding of guilt, but it moves fast and warrants immediate representation.

When the concern is about your everyday conduct, not one incident

Not every case centres on a single clinical decision. Sometimes the pattern under scrutiny is broader, delegation, documentation, communication with the wider team, standing conduct rather than a discrete event. Our NMC Professionalism course addresses exactly that side of the Code.

Questions answered

Frequently asked questions

How long does an NMC investigation usually take?+
The NMC's own target is resolving cases within 15 months end-to-end, and around 74% of cases met that target as of February 2026 data. This is a rolling performance metric, not a guarantee, and complex cases can take considerably longer. The investigation stage itself is targeted at 25 weeks.
Will an NMC concern definitely end my career?+
No. Only around 10% of cases that reach Case Examiners are referred on to a full hearing. Many cases close at screening or with no case to answer, and outcomes like advice, a warning, or undertakings are far more common than removal from the register.
What's the difference between a warning and undertakings?+
A warning is a formal, public record on the register, visible for 12 months, but doesn't restrict your practice. Undertakings are voluntary conditions you agree to, also published on the register, which do actively restrict or shape how you practise while they apply.
Can I keep working while under investigation?+
In most cases, yes. Your registration continues as normal unless an Interim Orders Panel has imposed restrictions or suspension, which is reserved for cases involving a serious, immediate risk.
Do I need a solicitor, or is my union or indemnity provider enough?+
Your professional indemnity provider or union is usually the right first call. A solicitor may become relevant for more complex or serious cases, particularly ahead of a Fitness to Practise Committee hearing, often on their recommendation.
What is a consensual panel determination?+
It's an outcome specific to the NMC process where a sanction is agreed between you and the NMC without a full hearing, used in appropriate cases where both sides agree on the facts and the right outcome, resolving the case more quickly than a contested hearing.
What happens if I don't respond to the letter?+
The investigation continues regardless, based on whatever evidence the NMC already has. Not responding removes your opportunity to shape the outcome with your own account, insight, and evidence of any action already taken.
Will my employer be told about the investigation?+
The NMC doesn't automatically notify your employer as a routine step. Many NHS Trusts and employment contracts carry their own separate duty to disclose an ongoing regulatory concern, and an interim order, if one is imposed, is recorded on the public register, which an employer can check.
