What counts as a sudden or unexpected death?

A death may be treated as sudden or unexpected if it happens without warning, the cause is unknown, or the person hadn’t been seen by a doctor recently. This can include deaths:

At home
In a care home
In hospital
In public
While travelling

When a death is unexpected, professionals may need to involve the coroner. That can affect when a death certificate is issued and when a funeral can be arranged.

What to do immediately

1) Make sure you’re safe and get urgent help if needed

If you think the person may still be alive, call 999 immediately.

If the person has died and you are at home, call 111 (or 999 if there are urgent concerns, risk, or you feel unsafe). If the death is in a public place, call 999.

2) Don’t move anything unless you’re told to

If the death is unexpected, try not to move the person or disturb the scene. This isn’t to “treat anyone like a suspect” – it’s simply because professionals may need to understand what happened.

3) Contact the right professional depending on where the death happened

If the death happens at home: call 111 or the person’s GP practice (if open). A clinician may attend and advise next steps.
If the death happens in a care home: staff will follow their procedures and contact the appropriate clinician.
If the death happens in hospital: the hospital team will guide you.
If the death happens abroad: the process is different and can take longer.

4) Be prepared for police involvement

In sudden or unexplained deaths, the police may attend. This can feel frightening, but it is often a standard part of the process to confirm circumstances and ensure the right referrals are made.

5) Understand what happens if the coroner is involved

If the cause of death is unknown, the death is violent/unnatural, or there are other concerns, a doctor may refer the death to the coroner.

If the coroner is involved:

The person may be taken to a mortuary for examination.
A post-mortem may be required.
The Medical Certificate of Cause of Death (MCCD) may not be issued straight away.
The funeral may need to wait until the coroner gives permission.

6) Choose a funeral director – but know you may not be able to set a date yet

You can still contact a funeral director early to start discussing options and preferences, even if you’re waiting on the coroner.

We know that for most people, this is a daunting decision to make, so we’ve created a guide to help you choose the best funeral director for you, see our guide to Choosing a funeral director.

Why Choose Best Funerals?

When someone dies suddenly, the last thing you need is added pressure to “shop around” for a funeral director.

Best Funerals takes the stress out of finding the right help. When you contact us we’ll connect you with the one independent Funeral Director in your area we have carefully selected, after vetting for consistently high standards of professionalism, compassion and personal care.

With Best Funerals you can move forward with confidence, without spending hours making calls at a difficult time.

And if the coroner is involved and dates can’t be confirmed yet, we can still help you understand the next steps and what can be arranged now versus what may need to wait.

7) When you can register the death

Registration of the death depends on whether the cause of death is known and whether the coroner is involved.

If the Medical Certificate of Cause of Death (MCCD) is issued promptly, you can usually register within the required timeframe.
If the coroner is involved, registration may happen later, and you may receive different paperwork.

Care of the deceased and seeing them

Families often worry they won’t be able to see their loved one if the death is unexpected. In many cases, viewing is possible later – but timing and location depend on the circumstances and any coroner’s process.

Practical tips for the first 24 hours after a sudden or unexpected death

Ask someone to be with you if possible – even just to sit quietly.
Write down names and reference numbers (police, coroner’s office, hospital ward).
Collect key details you may be asked for: full name, date of birth, NHS number (if known), GP details.
Avoid making big decisions immediately if you can. It’s okay to pause.

When to seek extra support

A sudden death can bring shock, trauma, guilt, anger, or numbness – sometimes all at once. If you’re struggling, consider speaking to your GP, a bereavement charity, or a trusted counsellor.

If you’d like to talk through options for next steps with a calm, independent guide, Best Funerals can help you understand the process and connect you with a trusted local independent funeral director.

FAQ Section

Below are answers to some of the most common questions families ask after a sudden or unexpected death. If you can’t find what you need, it’s OK — every situation is different. You can also read our wider step-by-step guide here: What to do when someone dies.

Do I need to call 999 if someone dies suddenly?

If you believe the person may still be alive, call 999. If the person has clearly died at home, call 111 (or 999 if you feel unsafe or there are urgent concerns). In a public place, call 999.

Will the police come?

Sometimes, yes. In sudden or unexplained deaths, police attendance can be routine. Their role is typically to establish what happened and ensure the right medical and coroner processes are followed.

Does a sudden death always go to the coroner?

Not always, but it’s common when the cause of death isn’t clear or the death is unexpected. A doctor or the police may refer the death to the coroner.

Can we start arranging the funeral if the coroner is involved?

Yes – you can contact a funeral director and discuss preferences. However, you may not be able to confirm a date until the coroner has given permission.

How long does the coroner process take?

It varies. Some cases are resolved quickly; others take longer if tests are needed or an inquest is required.

Can we see our loved one if there is a post-mortem?

Often, yes – but it may be later and may depend on the circumstances. Your funeral director or the coroner’s office can advise.

When can we register the death?

If the cause of death is confirmed and the Medical Certificate of Cause of Death (MCCD) is issued, you can register as normal. If the coroner is involved, registration may happen later and you may receive different paperwork.

What if the death happened abroad?

The steps and timescales are different, and repatriation may be needed. See: What to do when someone dies abroad: https://bestfunerals.co.uk/help-and-guidance/what-to-do-when-someone-dies/abroad/
