The Duty of Candour is a legal requirement for all NHS and CQC-registered providers in England to be open and honest with patients when a notifiable safety incident causes moderate to severe harm or death. It was introduced for NHS bodies in November 2014 and extended in April 2015 to all other Care Quality Commission-registered providers.
If you're reading this, there's a good chance something in your care feels wrong. A test result was missed. A referral was delayed. A medication caused harm. Or a clinician has spoken to you in fragments, with half-explanations and no clear account of what happened. That uncertainty is exhausting, and you don't have to accept it.
The NHS Duty of Candour matters because it turns honesty from a vague ideal into something patients can demand. It gives you a framework for asking direct questions, expecting proper follow-up, and challenging providers who try to smooth over serious mistakes with a quick apology and nothing more.
Silence after harm isn't just upsetting. In the right circumstances, it's a failure of duty. Patients deserve the truth, a record of what happened, and a clear explanation of what will be done next.

Introduction A Patient's Need for Openness
You leave an appointment knowing something has gone badly wrong, but nobody says it plainly. One person tells you the complication was “unfortunate”. Another says the team is “reviewing things”. You ask what happened and get a careful answer that sounds polished but empty. You're left doing the hardest part alone, trying to work out whether this was bad luck, poor care, or a mistake nobody wants to name.
That's where many patients get stuck. Not because they don't know something happened, but because the system often speaks in a way that blurs responsibility. It gives snippets instead of facts. It offers sympathy without substance.
The Duty of Candour exists for exactly this kind of moment. It's the formal mechanism that should stop organisations retreating into vagueness after a serious safety incident. It says patients should be told what is known, what will be investigated, and what will happen next. That matters because people can't make decisions, protect themselves, or pursue a complaint if the provider controls all the information.
You are not being difficult by asking for a clear explanation. You are asking for the standard of openness the system is supposed to provide.
Patients often assume candour is just a nicer word for apology. It isn't. A proper candour response should create a record, trigger follow-up, and give you something concrete to work with. If the provider says sorry but won't explain the event, won't confirm things in writing, or won't tell you what review is happening, that's not good enough.
You don't need to be a lawyer to use this. You need a practical grip on what the duty is, when it applies, and how to push for compliance when a provider starts dodging.
Understanding the NHS Duty of Candour
The short version of what is Duty of Candour NHS is this. It's the rule that says healthcare providers must be open with patients when serious harm has occurred through a safety incident. In England, the statutory duty was introduced for NHS bodies in November 2014 and then extended in April 2015 to all other CQC-registered care providers under Regulation 20 of the Health and Social Care Act 2008 (Regulated Activities) Regulations 2014, as set out in the MDU guide to the duty of candour.
Professional honesty versus legal duty
There are really two levels here.
The first is the everyday professional duty. Clinicians should be honest with patients as a basic part of decent care. If something has gone wrong, they shouldn't hide behind jargon or wait for a formal complaint before speaking plainly.
The second is the statutory duty, which is the legal one. This is not optional. Once the legal threshold is reached, the organisation must act. That includes telling the patient what is known, explaining what further enquiries will happen, offering an apology, and keeping a written record.
A simple way to think about it is this:
- Professional duty is the ordinary expectation that staff act with candour.
- Statutory duty is the law stepping in after a serious safety incident and requiring a formal response.
If a provider tries to treat a serious incident like a casual bedside conversation, they're missing the point. The legal duty is supposed to produce accountability, not just softer language.
Who has to follow it
This applies broadly across organisations delivering regulated care in England. That includes NHS bodies and other providers registered with the Care Quality Commission. So if you were treated by an NHS trust, a private hospital, or another regulated care provider, the duty may still apply.
Patients often make the mistake of focusing only on individual clinicians. In practice, the duty sits on the organisation. That matters because you're not chasing a personal favour from one doctor or nurse. You're asserting a legal expectation against the provider itself.
Practical rule: address your request to the organisation as well as the clinician. Ask the trust, practice, or provider to confirm whether the statutory Duty of Candour has been triggered.
That keeps the issue where it belongs. On the record, and at organisational level.
When Is the Duty of Candour Triggered
The legal trigger is a notifiable safety incident. That phrase sounds technical, but the patient-side question is simpler. Did something happen in your care that caused serious harm, or create a situation where serious harm followed and the provider now has a duty to be open about it?
Patients often hesitate here because they think they need to prove negligence first. They don't. Candour is about openness after a serious incident. It is not the same thing as winning a legal claim.
What a notifiable safety incident means in practice
In plain English, think about situations like these:
A treatment error with lasting consequences
A medication mistake leads to a serious reaction and extended recovery.A missed diagnosis that allows harm to worsen
A provider overlooks clear warning signs, and the delay leads to a much more serious condition by the time you are properly assessed.A procedure complication that should be disclosed formally
Something goes wrong during surgery or another intervention, and the impact is more than minor or short-lived.Psychological harm that is prolonged and significant
The duty isn't limited to visible physical injury. Mental health consequences can matter too where the harm is serious enough.
You do not need to use the provider's internal terminology perfectly. Patients get too hung up on naming the category. What matters is describing the incident, the harm, and why you believe the statutory process should have been triggered.
Situations patients often overlook
Candour isn't only relevant when a provider openly admits there was a mistake. Sometimes the strongest clue is the opposite. Sudden defensiveness. Confused explanations. Notes that don't match what you were told. A rushed apology with no written follow-up.
These are common warning signs:
- You were told something happened, but not given a clear account
- Staff mentioned a review or investigation, but gave no timescale
- You received an apology, but nothing in writing
- Different staff gave inconsistent explanations
- The provider focused on your complaint tone instead of the incident itself
If that sounds familiar, raise the issue directly. Ask whether the provider considers this a notifiable safety incident and, if not, ask them to explain why in writing. That question alone often sharpens the conversation.
Your Rights and What Providers Must Do
Once candour is triggered, the provider is supposed to do more than talk. NHS guidance requires an in-person notification where possible, followed by written confirmation and a secure record of communications. In Wales, the NHS model also includes a five working day written follow-up after the in-person discussion and requires investigation into what happened and how recurrence will be prevented. Failure to comply with the statutory duty can lead to criminal sanctions, including fines and possible de-registration, as explained in NHS Resolution's duty of candour guidance.
That tells you something important. This process is meant to be structured, documented, and traceable. Not informal. Not vague. Not left to memory.
What should happen after candour is triggered
From a patient perspective, you should expect the following.
A direct conversation
Where possible, the provider should speak to you in person. This is not something they should bury in a generic letter if a proper discussion can happen.A truthful account of what is known so far
Not every fact will be available immediately, but they should tell you what they do know.An explanation of further enquiries
You should be told what will be investigated or reviewed next.A genuine apology
An apology is part of the process. It is not a substitute for the rest of the process.Written confirmation
What was discussed should be followed up in writing, and the provider should keep a secure record.
The best way to judge whether candour has been done properly is simple. Ask yourself whether you could show the paperwork to an independent person and they would understand what happened, what is still being investigated, and what the provider committed to doing next. If not, the process is probably incomplete.

Duty of Candour what to expect vs common misconceptions
| What You Should Expect | Common Misconceptions or Failings |
|---|---|
| A real explanation of the incident | “We said sorry, so that covers it” |
| An in-person discussion where possible | A brief phone call with no follow-up |
| Written confirmation after the discussion | Nothing in writing at all |
| Clear information on what will be investigated | “We'll look into it” with no detail |
| A record of communications | Informal conversations that vanish from the record |
| An apology alongside facts and follow-up | An apology used to shut the matter down |
An apology is necessary, but it is not the end of the process. If the provider treats it as the end, push back.
Practical Steps for Patients to Uphold Their Rights
This is the part that matters most. Knowing the duty exists is useful. Using it properly is what gets results.
The hard truth is that patients often have to be more organised than the provider. That's not fair, but it is reality. A government call for evidence found that only 2 in 5 respondents said the purpose of the statutory duty of candour was clear and well understood, 54% said staff did not know or understand its requirements, and less than 1 in 4 said it was correctly complied with when a notifiable safety incident occurred, according to the Department of Health and Social Care findings on the statutory duty of candour.
That means you shouldn't wait politely and hope the system sorts itself out. Be direct. Be specific. Put things in writing.
What to say to the provider
You do not need clever wording. You need firm wording.
Use sentences like these:
- “I believe a notifiable safety incident may have occurred, and I am asking the provider to confirm whether the statutory Duty of Candour has been triggered.”
- “Please explain in writing what is currently known about the incident, what further enquiries are taking place, and when I should expect written follow-up.”
- “Please confirm who is responsible for managing the Duty of Candour process in this organisation.”
- “I want a written record of the candour discussion and copies of relevant correspondence.”
- “If you do not consider the duty applicable, please explain that decision in writing.”
Those phrases do two jobs. They show that you know the issue is formal, and they force the provider to either comply or state their position clearly.
A helpful next step is learning how to request your records cleanly and formally. This guide on making a subject access request to your GP can help you build the paper trail.
To understand the process visually, this short explainer is worth watching.
What to ask for in writing
Don't ask vaguely for “everything”. Ask for defined items.
A written account of the incident
Ask what happened, when, and what harm the provider believes resulted.Confirmation of whether candour has been triggered
If yes, ask for the formal record. If no, ask for the reason.Details of any investigation or review
Ask who is carrying it out and what issues are being examined.Copies of correspondence and records of meetings
You want the written trail, not just verbal assurances.Relevant medical records and results
These often expose timeline gaps and contradictions.
Also keep your own log. Note dates, times, names, job titles, and the exact wording used if possible. If a provider changes its story later, your notes matter.
Write as if you may need to show the entire timeline to a complaints manager or the Ombudsman later. Because you might.
What to Do When Candour Fails The NHS Complaints Process
When a provider avoids candour, you should treat that as a complaint issue in its own right. Not as a side note. Not as bad communication. If the organisation failed to be open after a serious incident, that failure belongs in your complaint clearly and prominently.
A key patient expectation after candour is triggered is to be meaningfully involved in a review and to agree on actions to improve care. When that follow-up process fails, it is not just a communication problem. It can become a central part of a formal complaint to the ICB or PHSO, as reflected in this patient guide to duty of candour from Cambridge University Hospitals.
How to escalate properly
If the provider hasn't handled candour properly, follow a clear escalation route:
Raise it with the provider first
Write to the complaints team, practice manager, or relevant department and state that openness after the incident was inadequate.Use the formal NHS complaints route
If the response is weak or evasive, escalate through the proper complaints pathway.Take it beyond the provider if needed
If local resolution fails, the issue can move onward for independent review.
If you're unsure when to use an informal route and when to go formal, this guide on PALS versus a formal complaint is useful.
What to put in your complaint
Your complaint should not just describe the clinical event. It should spell out the candour failure.
Include points like these:
The incident itself
State what happened and why you believe it was serious enough to trigger candour.What the provider failed to do
No in-person discussion, no written follow-up, no clear explanation, no record, no apology, or no investigation details.The practical impact on you
Confusion, delayed understanding, inability to make informed decisions, distress, or loss of trust.What you want now
A full written response, proper candour compliance, disclosure of records, involvement in review, and clear actions to prevent recurrence.
Keep the complaint structured. Providers often evade messy complaints more easily than disciplined ones. A calm, chronological letter is harder to ignore than five angry pages with no timeline.
Duty of Candour Frequently Asked Questions
Is an apology an admission of legal guilt
No. An apology is part of the candour process. It should not be treated as a legal confession, and patients should not let providers hide behind that excuse to avoid saying sorry.
Does the Duty of Candour only apply in hospitals
No. In England, it applies to NHS bodies and other CQC-registered care providers. The key question is not whether the setting was a hospital. It is whether the organisation is covered and whether a notifiable safety incident occurred.
Does it apply to psychological harm
Yes. Serious psychological harm can be relevant. Patients often underestimate this, especially after traumatic care events.
Is Duty of Candour the same as making a complaint
No. They are connected but different. Candour is the provider's obligation to be open after a serious incident. A complaint is your route to challenge failures, including failures of candour.
Does it work the same way across the UK
No. The legal framework differs by nation and setting. That matters if your care took place outside England or involved cross-border services. Always ask the provider which legal framework they are applying.
What if the provider says candour was not triggered
Ask for that decision in writing, with reasons. Don't accept a verbal dismissal. Once they commit their position to paper, you have something concrete to challenge.
If you need help turning a messy medical problem into a clear written paper trail, Finally Seen Ltd is built for exactly that. They draft formal, personalised letters to your GP using the exact NICE guidance your GP is expected to follow, and they also provide a complaints pack for escalation if the response is poor or delayed. For patients who are exhausted, dismissed, or stuck in NHS limbo, that kind of structure can make the difference between being ignored and being taken seriously.
