Cremation Process in the UK: How Cremation Works and What Happens During Cremation

The cremation process can feel mysterious if you have never arranged one before. Most families know the broad idea, but not the actual steps: what paperwork is needed, who does what, what happens at the crematorium, and when the ashes come back.

In the UK, cremation is a regulated process. A cremation cannot happen until the right documents have been completed, the death has been registered or authorised, and the crematorium has permission to proceed. GOV.UK explains that, after a death is registered, the registrar issues the Certificate for Burial or Cremation, often called the “green form”, which gives authority for the funeral arrangements to go ahead.

In this guide, we’ll explain how cremation works in the UK, what happens before and after, and how direct cremation, specifically, keeps the process simple.

Crystal Funeral Planning offers a direct cremation plan from £1,425, including collection, care of the deceased, a coffin, cremation fees, doctors’ fees where required, transport to the crematorium, and hand-delivery of ashes.

Key Takeaways

• The UK cremation process normally includes paperwork, collection, care of the deceased, transport to the crematorium, cremation, and the return of the ashes.
• The applicant is usually a next of kin or executor over 16.
• A funeral provider or a direct cremation service can help complete the forms and arrange the documentation.
• The crematorium checks identity, paperwork, and authorisation before cremation takes place.
• Ashes may be ready at the crematorium within one to three working days, but return to the family depends on the provider.

Cremation Process UK: Step-by-Step

The cremation process UK families usually follow can be broken into three main stages:

The exact process may vary slightly depending on where the death happened, whether the coroner is involved, and whether you choose a traditional funeral or direct cremation.

What Happens Before Cremation

In simple terms, this stage usually involves:

• Registering the death
• Receiving the green form, where applicable
• Choosing a funeral provider or direct cremation provider
• Confirming who is arranging the cremation
• Completing cremation forms
• Deciding what should happen to the Ashes
• Arranging the collection and care of the person who has died

Before cremation can take place, the death needs to be medically certified and registered, unless the coroner is involved. The person arranging the cremation, usually the next of kin, provided they are over 16, or the executor, also completes the cremation application.

Here’s everything you need to have ready to fill in the cremation application.

A provider can make this much easier. A crematorium or funeral service provider can advise on what needs to happen, help complete the relevant forms, and arrange for other documentation to be completed.

With Crystal Funeral Planning, these practical arrangements are part of the direct cremation service. The plan includes 24-hour collection, transport to a nominated mortuary, preparation and care of the deceased, a coffin, and all transportation costs on the day of cremation.

What Happens in a Cremation

When people ask what happens during cremation, they are often worried it will be explained in too much detail. The important thing to know is that it is a controlled, professional process carried out by trained crematorium staff who know exactly what they are doing. The body is prepared for cremation with complete sensitivity and respect.

Before the cremation, the crematorium checks the paperwork and identity details. The Code of Cremation Practice says a coffin should not be accepted unless it bears adequate particulars of the identity of the person inside. This usually means the coffin needs to be properly labelled with the deceased’s identity details.

The coffin is then placed into the cremator, and the process of physical cremation takes around 1–2 hours. The Code of Cremation Practice states that once the coffin has been placed in the cremator, it is not touched or interfered with until the cremation is complete. After cremation, the whole of the ashes, less any metals, are collected and handled according to the instructions received.

A direct cremation follows the same professional process, but without mourners present and without a funeral service at the crematorium. This is the core difference between direct cremation and an attended cremation.

Direct cremation is often cheaper because it eliminates the costs associated with an attended service. SunLife’s Cost of Dying Report puts the average direct cremation cost at £1,628, compared with £3,518 for a simple attended cremation and £4,510 for a traditional attended funeral.

How Does Cremation Work UK: Roles and Responsibilities

A cremation involves several people or organisations. Understanding who does what makes the process much clearer when you’re preparing for a loved on to be cremated.

Crematorium vs Funeral Provider

The crematorium and funeral provider have different roles.

The crematorium is responsible for making sure it has the authority to cremate. The funeral provider is usually the family’s practical point of contact.

This is where Crystal’s direct cremation service is designed to reduce stress. Instead of asking families to coordinate collection, care, transport, crematorium arrangements, paperwork support, and ashes return separately, we bundle these essentials into one direct cremation plan. The current plan includes collection, care, a coffin, cremation fees, doctors’ fees, transport, and hand-delivery of ashes. 

It’s designed to remove as much of the burden from you as possible.

Documentation and Authorisation

The documentation stage is one of the most important parts of how cremation works. A cremation cannot go ahead simply because a family requests it. The correct authorisation must be in place first.

Here are the documents you’ll need:

• Medical Certificate of Cause of Death, known as the MCCD, or confirmation that the Medical Examiner/coroner process has been completed.
• Certificate for Burial or Cremation, often called the green form. This is issued after death registration and is one of the documents that gives the crematorium authority to cremate. It must be sent to the crematorium with the cremation application.
• Coroner’s certificate, if the death has been referred to and authorised by the coroner.
• Completed Cremation 1 form, signed by the applicant. Cremation 1 is the key form the applicant must fill out.
• Any relevant implant information, especially if there may be a pacemaker, ICD, radioactive implant, drug pump, neurostimulator, Fixion nail, or other battery-powered or pressurised implant. These are devices that could cause problems during cremation.
• Photo ID for whoever collects the ashes, if ashes are being collected from the crematorium. The person collecting ashes should bring identification.

The green form is one of the documents that authorise the crematorium to cremate, and it must be sent to the crematorium along with the cremation application. You must also decide what should happen to the ashes. This decision is part of the cremation application process. More on this below.

This is why choosing a clear, supportive provider matters. Families should not have to feel alone with the administration. Your provider can help get the right forms filled in and sent, as well as anything else you’re not sure of. 

What Happens After Cremation

Before cremation, you would have decided what should happen to the ashes. Families may choose to have ashes returned, collected, scattered, interred, or held temporarily while they decide what to do. After cremation, the ashes are prepared and either returned to the family, collected, scattered, interred, or held until a decision it made.

Ashes can be held temporarily if you’re not sure what you want to do, but crematoria will not hold them indefinitely and may charge after a certain period.

Ashes Return Times

Families often ask: how long after cremation are ashes ready in the UK? There are two answers. First, there is the time it takes for the crematorium to make ashes available. Then there is the time it takes for the funeral provider to return them to the family.

Some crematoria release ashes quickly; however, this does not always mean the family receives ashes immediately. The provider may need to collect them, prepare them for return, arrange delivery, and complete any checks, so this adds time to the process.

We hand-deliver ashes within 28 days of cremation, and this is included in the cost of our direct cremation plan.

What to Do With Ashes

Once ashes are returned, there is no need to make an immediate decision. Many families take time before choosing what feels right.

Common options include:

• Keeping Ashes at home in an urn or burying them in the garden
• Scattering ashes somewhere meaningful, with permission
• Interring ashes in a cemetery, crematorium garden, or existing grave
• Dividing Ashes between family members
• Using ashes in keepsake jewellery or memorial items
• Holding a memorial or celebration of life later

If scattering ashes, it’s important to check for permission, depending on where you are. Permissions are not the same everywhere. For example, Southend-on-Sea City Council says ashes can be scattered over land or water, but you first need permission from the landowner. It also says ashes are not allowed to be scattered or interred in its formal parks and open spaces, except for the Scatter Lawn at Southend Crematorium by appointment. You can check the local authority’s website to find out details in your area.

You may also wish to post some or all of the ashes or take them with you on a plane. If so, it’s important to check with your chosen courier or provider if there are any requirements.

Some families choose direct cremation specifically because it gives them more flexibility afterwards. SunLife reports that 86% of people who arranged a direct cremation still held a memorial service or celebration of life of some kind. Direct cremation takes the pressure off, so you can celebrate your loved one in the way they would have wanted or the way that works for you.

Final Thoughts on the Cremation Process

The cremation process is much the same across the UK, varying slightly depending on the provider, crematorium, and specific wishes or requirements. For families, the easiest way forward is to choose a provider that explains the process clearly and includes the essentials up front.

Crystal Funeral Planning is there for people who want a simple, low-cost direct cremation without needing to coordinate each stage themselves. Its plan includes collection, care of the deceased, a coffin, cremation fees, doctors’ fees where required, transport to the crematorium, and hand-delivery of ashes within 28 days.

That means families can focus less on the logistics and more on deciding how they want to remember the person who has died.
