When a property has been examined as part of a police investigation, someone still has to put it back to rights once the investigators have gone. That is where forensic cleaning comes in. We attend properties nationwide, any time of day or night, to carry out the specialist decontamination that follows forensic examination, working discreetly and with full respect for what the people involved have been through. Every technician we send is fully insured and trained to remove and dispose of contaminated material as licensed clinical waste. To arrange a visit, request a callback or email [email protected].
What is forensic cleaning?
Forensic cleaning is the decontamination work carried out after a property has been examined as part of a police or coroner’s investigation and formally released back to its owner or occupier. It sits alongside crime scene cleaning, and in everyday use the two terms are often applied to the same job. If there is a distinction worth drawing, it is one of sequence: crime scene cleaning describes the whole process of making a property safe after a serious incident, while forensic cleaning points more precisely to the stage that begins once officers have finished gathering evidence and released the area for cleaning.
In practice, both involve the same core work. Blood, bodily fluids and other biological material left behind after an incident carry a genuine infection risk and cannot be treated as ordinary mess. Cleaning it correctly means more than removing what is visible; it means disinfecting to a clinical standard, dealing with anything porous that has absorbed contamination, and confirming the area is safe before anyone else re-enters. Our related crime scene cleaning and trauma cleaning pages go into more detail on the wider incident response; this page focuses on what happens once forensic examination has taken place.
When is forensic cleaning needed?
Forensic cleaning is typically needed after a property has been used as part of a criminal investigation, including cases involving violence, an unexplained death, or another serious incident that required police attendance and examination. It also applies where a coroner’s investigation has taken place, or where forensic officers have been present for any other reason and have since released the scene.
We are contacted by a wide range of people in these situations. Families want their home returned to a normal, liveable state without having to face the aftermath themselves. Landlords and letting agents need a rental property brought back to a safe, lettable condition, often against a tight turnaround before a new tenancy can begin. Employers may need a workplace decontaminated after an incident on site, and councils sometimes commission the work for properties they manage. The starting point is always the same: the scene must be released by investigators before any cleaning work can begin.
How we handle it
- Assess, a technician reviews the property, confirms the scene has been formally released, and agrees the scope of work and a written price before anything begins.
- Contain the area, affected rooms are sealed off and protected to stop contamination spreading to unaffected parts of the property.
- Remove contaminated items as clinical waste, anything that cannot be safely cleaned, such as heavily soiled soft furnishings or flooring, is bagged and removed under clinical waste procedures.
- Clean and disinfect to a clinical standard, surfaces, fixtures and any porous materials that can be saved are cleaned using hospital-grade disinfectants suited to bloodborne pathogens and other biological contamination.
- Deodorise, specialist equipment is used to neutralise odour at its source rather than masking it, which matters particularly where contamination has been present for some time.
- Verify the area is safe, the property is checked over before we consider the job complete, so it can be handed back with confidence.
- Hand over the waste documentation, paperwork confirming how contaminated material was removed and disposed of is provided for your records.
Health, safety and compliance
Forensic cleaning involves direct contact with bloodborne pathogens and other biological hazards, so it is carried out under strict safety procedures throughout. Our technicians wear appropriate personal protective equipment for the task, follow set procedures for handling contaminated material safely, and use hospital-grade disinfectants suited to the type of contamination present. All clinical waste generated during the job is removed by a licensed clinical-waste carrier and disposed of in line with Environment Agency waste regulations, with the relevant paperwork provided once the work is finished. Technicians are trained and vetted, and the whole visit is carried out with discretion, mindful that a property in this situation is rarely an easy one to be in.
What forensic cleaning typically costs
Costs vary considerably depending on the size of the affected area, how much material needs to be removed as clinical waste, and how long contamination has been present. As a general guide, most forensic and trauma cleans fall roughly in the £600–£3,000 range, though every property is different. We always agree a written price before any work begins, and the initial assessment is free, so you know exactly what is involved before committing to anything. For a fuller breakdown of what affects pricing, see our biohazard cleaning cost guide.
Is it covered by insurance?
Forensic cleaning is often covered under a buildings or contents insurance policy, particularly where the underlying incident involved a crime, an accident or an unattended death. Policies and circumstances vary, so cover is never guaranteed, but where a policy is in place we can liaise directly with the insurer on your behalf and supply the documentation they usually require, including a written scope of work and waste transfer paperwork. More detail is available on our insurance claims page, and we are happy to talk you through the process before any work begins.
Why choose a professional service
Forensic contamination is a genuine health hazard, not a job for standard household cleaning products, and getting it wrong can mean the risk simply resurfaces later. A professional service brings the training, PPE and hospital-grade disinfectants needed to deal with it properly the first time, along with the licensed route required to dispose of clinical waste legally. Just as importantly, it means the family, landlord or business involved does not have to face that work themselves at what is often an already difficult time. We attend properties across England, Scotland and Wales, and every visit is carried out with the same discretion and care, whether the property is a family home, a rented flat or a commercial unit.
