Inside a crematorium - understanding the process

For many people, the idea of a crematorium is unsettling and even a little daunting. At Levertons, we believe that openness and clarity help families feel more confident in their choices. In this article, we take you behind the scenes – step by step- so you know exactly what happens in a crematorium, and we answer some frequently asked questions.

From death to cremation: The early steps

1. Verification and paperwork

Before any cremation can proceed, certain legal and medical steps must be completed. A Medical of Cause of Death (MCCD) must be issued, and the death must be formally registered. If a coroner or further investigation is involved, that can delay matters. Only once all the legal formalities are in place can the cremation take place. See “when someone dies” section on our website for more information.

2. Transfer and preparation

The funeral director collects the deceased from the place of death or mortuary and the funeral director brings them to their care. At Levertons, the body is treated with dignity and respect: cleaned, dressed in clothing or a shroud (depending on family wishes), and any medical devices or jewellery removed (unless the family prefers the latter to remain).

Embalming is optional; it is often used when viewing is requested.

3. Booking the cremation slot

Cremations are booked in advance, and demand means slots may fill several days or even up to two weeks in advance (or more, depending on local pressure).

The funeral service and committal

If the family chooses an attended funeral, the ceremony usually takes place in the chapel on the day of cremation, although if the ceremony is later in the day, the cremation may not take place until the following working day.

  • Mourners arrive, the coffin is brought into the chapel (often placed on a catafalque, or raised platform)
  • The service (readings, hymns, eulogies, prayers) typically lasts 30 to 45 minutes (though that may be extended)
  • At the point of committal, the coffin is usually obscured from view (for example, withdrawn behind curtains or a gate) while the final respects are paid. However, families may take the option on the coffin remaining in view until everyone has left the chapel.
  • After the mourners depart, the coffin is moved from the chapel to the cremation (or charging) area.

Into the cremator: The cremation process

1. Identity checks and input

Before inserting the coffin, crematorium staff verify the identity of the deceased (matching nameplates, identity cards, or unique identifiers). This ensures the correct body is cremated.

2. Charging the coffin

The coffin (with the body inside) is placed in the cremation chamber (sometimes also called the “retort”) for cremation. In the UK, the coffin and body are cremated together; the container is not removed prior to cremation. The Code of Cremation Practice forbids opening the coffin once it has been committed, except in very exceptional circumstances, and it must not be disturbed.

3. Duration and temperature

The actual cremation typically takes around 90 minutes to two hours (in some cases slightly more, depending on body size, coffin type and other factors). The chambers are extremely hot (in the region of 1,000-1,200oC or more.

4. Removal of metal and pulverisation (cremulation)

Once the ashes are cooled, any metallic parts – such as surgical pins, screws, dental plates are removed using magnets or by hand, and these are usually recycled. The rest is processed by a machine called a cremulator to reduce them to a fine granular ash.

5. Packaging and storage of ashes

The processed ashes are placed into a container or urn clearly labelled with the deceased’s details. They may be temporarily stored until they can be collected by the family or interred or scattered, depending on the arrangements.

Frequently Asked Questions

Q: Does the coffin get cremated too?

Yes - in the UK, the coffin or container is cremated along with the body. The Code of Cremation Practice requires that the coffin not be opened once it has been committed , and that it be cremated intact (unless there is a very exceptional reason). Coffins intended for cremation must be combustible and suitable.

Q: Are multiple bodies cremated together?

No. Each cremation chamber only accommodates one coffin at a time, and each case is handled separately to avoid any mixing of remains.

Q: Can families witness the cremation?

Generally, no. Mourners attend the funeral service, but they will not be present when the coffin is placed into the cremator. Families may be allowed to be able  to see the “charging” (the moment the coffin enters the chamber) for cultural or religious reasons, but it must be requested in advance of the funeral.

Q: How long does the process take (from start to finish)?

From coffin charging to cooled remains ready for processing, about 1.5 to 2 hours is typical. Including the time needed for preparation, paperwork, scheduling, and return of ashes, the full timeline may span several days to a week or more.

Q: When do families receive the ashes?

Ashes are typically not returned on the same day. After cooling, metal separation, and processing, the ashes are packaged, labelled, and made available for collection or interment as arranged.

Q: Can ashes be scattered or interred?

Yes - there are many options. Families may choose to collect the ashes to keep, inter them in a cemetery or crematorium plot, or scatter them in a memorial garden or a natural location (subject to local regulations). Many crematoriums have their own gardens of remembrance or scattering lawns.

Q: Can a cremation be arranged without a funeral director?

Yes, legally it is possible for the executor or next of kin to arrange a cremation themselves. However, they must adhere to all statutory requirements (transport, safety, paperwork, identity validation, etc). Many families prefer to use a funeral director because of the support and practical handling they provide. Many crematoria will only allow a cremation to be booked through a funeral director.

As funeral directors who have supported many families through the cremation journey of a loved one, we understand how important it is to know that the deceased is treated with care and dignity every step of the way. At Levertons, we never forget that behind every cremation is a person who was deeply loved - and a family doing their best to honour them.

Our role is to make sure everything is handled with respect, transparency, and kindness. We believe that when families understand what happens at each stage, it helps ease some of the uncertainty and allows them to focus on remembering and celebrating the life that was lived.

If there’s anything you’re unsure about - whether it’s how the process works, what happens afterwards, or simply what to expect - please don’t hesitate to ask. We’re always here to listen, to explain, and to support you in whatever way we can.

I chose Levertons to arrange my wife's funeral purely on the basis of recognising the name, and I am glad that I did so. Everything went very smoothly and it was obviously a very professional operation. I was particularly grateful for their recommendation of a humanist celebrant, Kate Hobson, who exceeded my expectations.

Our family came to Leverton & Sons for dad's funeral after being let down by another funeralcare company. From start to finish, Lorna at the Kentish Town branch was kind, caring and professional - giving us complete peace of mind and comfort that arrangements were in good hands. No question or request was too much and I wouldn't hesitate to recommend this company to anyone.

What a caring and considerate team at Leverton's Kentish Town. From the start, Lorna could not do enough to help with my aunt's funeral arrangements. She has been so kind and gentle, never making me feel rushed or unheard. The quality of the floral wreaths was excellent, just as Lorna described them. Since I do not live locally, I found Lorna went out of her way to make sure everything was perfect. Also, a thank you to Bill and his team, who were with us on the day. You eliminated so much of the stress, on an emotional day. Thank you to Leverton's, a first class professional funeral service, complete with care and consideration. Would recommend highly.

I had a very positive experience with Levertons Muswell Hill. My husband died abroad and the company managed the process of receiving his body and advised and supported me while the Coroner considered the matter. I was helped and guided in selecting a crematorium and talked through the process of planning an appropriate service for my beloved partner of 29 years. Levertons suggested a celebrant and I decided to use her services following an initial meeting which went very well. I felt supported in planning the service and was confident in incorporating elements from my husbands culture and my own, different, tradition of death. This came together on the day of the funeral in a very moving way and Deborah and other Levertons staff members managed the event in a manner that was respectful and thoroughly professional. I am pleased to recommend the company and feel that the fees charged were very reasonable considering the high quality of service.

James and the team were truly exceptional — kind, professional, and deeply considerate. They guided us through one of the hardest times with genuine compassion and understanding, taking care of every detail with respect and sensitivity. Our family felt fully supported, and my brother was treated with the utmost dignity throughout. We are profoundly grateful for their help and care.
