Crime scene cleaning in the UK

Crime scene cleaning is the removal of blood, other body fluids and other biological contamination from a place after a death or an injury, followed by disinfection and safe disposal of the waste. The name covers more than crimes: firms’ published services and prices put suicides and deaths that were not found for some time alongside assaults and violent deaths. The same service is sold as trauma cleaning, biohazard cleaning and forensic cleaning. Police forces use “forensic cleaning” for cleaning their own custody cells, vehicles and forensic areas.

A domestic cleaner is not equipped for it. You need a specialist when blood or body fluid has soaked into carpets, mattresses or floors, when there may be needles, or when contaminated waste has to be removed, because that waste has to be classified and carried under the waste rules and the work falls under the health and safety controls for blood-borne viruses (both explained below).

For a family arranging this after a death, suicide or injury at home, our page on trauma cleaning after a death, suicide or injury covers the same service with the family’s questions in mind.

Plan on arranging it yourself. The police and coroner guidance we checked for England and Wales describes the investigation, evidence, examination of the body and its release. It does not say that the police or the coroner will clean the home, and we found no national scheme that does. Ask the investigating officer whether anything will be arranged before you book a firm.

Police forces do buy specialist cleaning. The contracts we found are mostly for their own premises and vehicles; some also mention crime scenes without saying whose. Merseyside Police’s forensic cleaning contract (from October 2025) covers custody, forensic areas and vehicles; Greater Manchester Police’s (from May 2026) covers custody, vehicles and crime-scene biohazards; Staffordshire Police’s covers buildings, custody cells, vehicles, forensic rooms and crime scenes; Gwent Police’s covers routine cleaning of its premises and vehicles as well as crime and sudden-death scenes. Where a contract mentions these scenes, the notices we reviewed do not say whose property. None of these is a promise to clean a family’s home.

The clean is arranged by whoever is responsible for the property:

• the owner, or the person who lives there;
• after a death, the executor or administrator of the estate;
• for a rented home, the landlord and the tenant (or, after a death, the tenant’s estate);
• for a shop, office, vehicle or communal area, the business, owner or managing agent.

In Scotland, the procurator fiscal (COPFS) investigates sudden, suspicious and unexplained deaths and may instruct police enquiries. In Northern Ireland, after an unexpected death at home, the police arrange removal of the body on the coroner’s behalf. Neither is a cleaning service. If the person who died was not found for some time, our guide to cleaning a home after an unattended death covers what can be saved and how the smell is removed.

Published UK figures vary widely, because every job is priced after an assessment. Three examples:

We found no single rule: it depends on who is responsible for the property and on any insurance. After a death, the executor or administrator is usually the person to arrange work on a home the person owned, and it is usually paid from the estate if the estate has the money. If you are unsure whether a cost can be paid from the estate, ask the executor or a solicitor. Being next of kin does not by itself make you personally liable for the estate’s debts.

Insurance depends on the policy wording. Saga’s March 2026 home policy, for example, covers contents damaged by bodily fluids after a death or injury, but excludes damage involving an illegal act. Some policies have a “trauma” section that pays for things such as counselling, temporary accommodation or security after a violent incident (Aviva’s archived Home 150 wording is one); that heading on its own does not mean cleaning is covered. Read the wording and ask the insurer before work starts.

Our who pays for cleaning after a death tool sets out the routes for owners, tenants, landlords and estates, and the questions to ask each.

No law we found prevents someone cleaning their own home after a crime. The guidance HSE gives to people who do this work shows why it is best left to them:

• Direct contact with blood and body fluids should be avoided where possible and limited to people with appropriate training. Gloves on their own do not make it safe.
• Blood-borne viruses can be passed on through a needle or sharp injury, or a splash to the eyes, mouth or broken skin.
• Dried blood can still be infectious: HSE explains that hepatitis B can remain infectious in dried blood.
• Some cleaning products react dangerously: bleach can release chlorine gas if it meets acids or acidic fluids such as urine.
• Clothing, shoes and equipment can carry contamination into other rooms.

We found no compulsory licence for this work in the UK. Check instead:

• Waste carrier registration on the public register for the nation where the firm is registered: England (Environment Agency), Wales (Natural Resources Wales), Scotland (SEPA), Northern Ireland (DAERA). Do not accept “fully licensed” on its own: ask for the registration number and the type of registration, and check it. Registration is not evidence of training.
• Training that names the course and the issuer, such as BICSc’s specialist units or IICRC’s Trauma and Crime Scene Technician certification (both described below).
• A written quote that separates cleaning, removal, waste disposal and any repairs, and states VAT.

Our guide to choosing a specialist cleaner has the full checklist and a way to compare two quotes.

What the work involves

The job is assessing contamination, planning the work, removing contaminated material, cleaning and disinfecting, and packing and handing over the waste correctly. The IICRC describes its Trauma and Crime Scene Technician course as covering hazard assessment, work plans and procedures for blood and other potentially infectious material. The work takes place in homes, vehicles and businesses, and on contracts for police forces (custody cells, vehicles, forensic areas) and councils.

Employers must assess and control their workers’ exposure to biological agents under the COSHH Regulations, and HSE says contact with blood and body fluids should be limited to people with appropriate training. That means protective equipment, controlled access, decontamination and training are part of the job, not extras.

Qualifications and training

We found no compulsory licence or qualification for crime scene cleaners in the UK. The training that exists is voluntary, and these are the schemes we could verify with the organisations that run them:

• British Institute of Cleaning Science (BICSc). Its Cleaning Professional’s Skills Suite starts with the “Licence to Practice”, which is BICSc’s own training and assessment, not a government licence. Its specialist units include SU1, bodily fluids and sharp objects, and SU2, bio-hazard decontamination cleaning, each with prerequisite units. BICSc skills training.
• IICRC Trauma and Crime Scene Technician (TCST). An international certification based on the US standard ANSI/IICRC S540, which is not UK law. IICRC TCST.
• British Damage Management Association (BDMA) Technician. A related accreditation for fire, flood and water-damage restoration, requiring experience, continuing professional development and an exam. It is not on its own a trauma cleaning qualification. BDMA Technician.

We found no statutory regulator for crime scene cleaners and no compulsory course, so before paying for training, check who issues the certificate and what it assesses.

Starting a firm

A business that carries other people’s waste generally needs to register as a waste carrier: in England, upper-tier registration, renewed every three years (Wales, Scotland and Northern Ireland have their own regulators). Hazardous waste generally needs a consignment note before it moves, and the firm has a duty of care to hand waste only to authorised people. Register as a waste carrier (GOV.UK).

Pay

We have not found a reliable, sourced UK figure for crime scene cleaners’ pay, so we do not give one.
