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 specialist decontamination of a property after a police or coroner’s investigation has finished and the scene has been formally released, removing blood, bodily fluids and other biological material to a clinical standard. 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 to the stage that begins once officers have finished gathering evidence and released the area. Both involve the same core work: disinfecting to a clinical standard, dealing with anything porous that has absorbed contamination, and confirming the area is safe before anyone re-enters. Our crime scene cleaning and trauma cleaning pages cover the wider incident response.
When is forensic cleaning needed?
Forensic cleaning is needed after a property has been used in a criminal or coroner’s investigation, including cases involving violence, an unexplained death or another serious incident that required forensic examination, once officers have released the scene. It also applies where forensic officers have been present for any other reason and have since handed the area back.
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 can begin.
What standards and regulations apply to forensic cleaning?
Forensic cleaning is governed by the Control of Substances Hazardous to Health Regulations 2002, which treat blood and bodily fluids as a bloodborne-pathogen hazard, and it can begin only once investigators have formally released the scene. The waste it produces is removed under the Environmental Protection Act 1990 duty of care by a licensed clinical-waste carrier.
Our technicians wear full protective equipment, including a coverall, gloves, eye protection and respiratory protection, typically an FFP3 respirator, where airborne risk calls for it, and clean with hospital-grade disinfectants tested for virucidal activity to standards such as BS EN 14476. Contaminated materials leave as clinical waste on a documented duty-of-care transfer, with the paperwork handed to you once the work is finished.
How is forensic cleaning carried out?
We carry out forensic cleaning in a set sequence that begins only after the scene is released, contains the area, and verifies it is safe before handover. The stages are consistent from job to job:
- Assess the property, confirm the scene has been formally released, and agree the scope and a written price before anything begins.
- Contain the area, sealing off affected rooms to stop contamination spreading to unaffected parts of the property.
- Remove contaminated items as clinical waste, including heavily soiled soft furnishings or flooring that cannot be safely cleaned.
- Clean and disinfect every affected surface and any porous materials that can be saved, using hospital-grade disinfectants suited to bloodborne pathogens.
- Deodorise the property, neutralising odour at its source rather than masking it, which matters where contamination has been present for some time.
- Verify the area is safe, checking the property over before we consider the job complete.
- Hand over the waste documentation, confirming how contaminated material was removed and disposed of for your records.
How much does forensic cleaning cost?
Forensic cleaning costs around £800 to £3,000 for most jobs, with a small, contained job starting nearer £600 and extensive contamination that needs flooring or structural removal running higher. These are indicative guide ranges to confirm at a free assessment, not fixed prices, because the size of the area, how long contamination has been present and the materials involved all move the figure.
| Situation | Guide range | What affects it |
|---|---|---|
| Contained single-incident clean | £600 to £1,500 | One room, limited spread |
| Forensic or crime scene clean | £800 to £3,000+ | Spread, materials affected, decontamination time |
| Extensive or multi-room contamination | £3,000+ | Flooring and subfloor strip-out, structural work |
We agree a written price before any work begins and the initial assessment is free. For a fuller breakdown of what moves the price, see our biohazard cleaning cost guide.
Is forensic cleaning 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.
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 on our insurance claims page, and we are happy to talk you through the process before any work begins.
Why choose Biohazard Cleaning for forensic cleaning?
Biohazard Cleaning brings trained, vetted technicians, full protective equipment, hospital-grade disinfectants and a licensed clinical-waste route to every forensic clean, carried out discreetly across England, Scotland and Wales. Forensic contamination is a real health hazard, not a job for standard cleaning products, and getting it wrong can mean the risk simply resurfaces later.
Working with a team that does this properly the first time means the family, landlord or business involved does not have to face the work themselves at an already difficult time, and it means the property is handed back genuinely safe rather than only looking clean. If you would like to talk it through, get in touch and we will take it from there.
