Biohazard cleaning is the safe removal and decontamination of biological hazards — blood, bodily fluids, chemical contamination, sharps, and other materials that pose a direct risk to human health. It's not something a standard cleaning company can or should attempt. The wrong approach spreads contamination, creates liability, and puts people at risk.
This type of work typically follows traumatic events, criminal incidents, or contamination emergencies. The people calling us are usually dealing with one of the worst days of their lives — property managers after an incident, landlords facing an unexpected situation, businesses needing to get premises safe and operational again. Jack and Max handle every biohazard job personally. No call centre, no strangers turning up at your door.



Biohazard situations don't wait for office hours. CrewConnect operates a 24/7 emergency response service across South Wales.
Here's what to expect:
Immediate response. Call 07350 136763 any time — day or night. Jack or Max will answer, assess the situation over the phone, and get a team mobilised. For emergencies in the Swansea area, we can typically be on site within 2 hours.
Discreet arrival. Our vehicles are unmarked. Our team arrives in plain clothing and changes into PPE on site. Neighbours, tenants, and passers-by won't know why we're there. Discretion matters in these situations, and we treat it seriously.
Full PPE and containment. Biohazard cleaning requires proper personal protective equipment — Tyvek suits, respirators, face shields, double gloving. We establish contamination zones, use negative air pressure where needed, and follow strict protocols to prevent cross-contamination.
Certified waste disposal. All biohazard waste is classified, packaged, and disposed of through licensed hazardous waste carriers in line with UK regulations. You receive full waste transfer documentation for your records.
Decontamination verification. Once cleaning is complete, we verify the decontamination using ATP testing where appropriate. The property is only signed off when it meets safe reoccupation standards.

CrewConnect provides specialist biohazard cleaning for a range of situations across South Wales:
Trauma scene cleanup — blood, bodily fluids, and biological material following accidents or incidents
Crime scene cleaning — restoration of premises after police release, evidence-aware cleaning protocols
Needle sweep and sharps removal — safe collection and disposal of hypodermic needles and sharps waste

Unattended death cleanup — full decontamination, odour neutralisation, restoration of the property
Hoarding cleanup — safe clearance of hoarded properties including biohazard material
Flood and fire damage — contamination cleanup following water ingress or fire damage (see also our mould removal services for post-flood mould)
Chemical contamination — decontamination of premises following chemical spills or drug-related contamination



Biohazard cleaning in the UK is governed by several pieces of legislation. CrewConnect operates in full compliance with:
The Environmental Protection Act 1990 — duty of care for waste handling and disposal
Hazardous Waste Regulations 2005 — classification, packaging, and transfer of hazardous waste
COSHH Regulations 2002 — control of substances hazardous to health during the cleaning process
Health and Safety at Work Act 1974 — risk assessments, safe systems of work, PPE provision
For crime scenes, we work with awareness of evidence preservation requirements and only attend premises after police release.

Questions
Here are answers to common questions about our cleaning services.

Biohazard cleaning is the specialist removal and decontamination of biological hazards — blood, bodily fluids, sharps, chemical contaminants, and other materials that pose health risks. It requires certified operatives, full PPE, and licensed waste disposal that standard cleaning companies aren't equipped to provide.
Common situations include trauma scenes, crime scenes, unattended deaths, needle contamination, hoarding properties, flood damage, sewage backups, chemical spills, and drug-related contamination. Any situation involving biological or chemical hazards that could harm health requires specialist cleaning.
We operate 24/7 across South Wales. For the Swansea area, typical response time is within 2 hours of your call. Cardiff and Newport are usually within 3-4 hours. Call 07350 136763 any time — Jack or Max will pick up.
Costs range from around £500 for contained single-room incidents to £5,000+ for extensive contamination across a whole property. It depends on the type of biohazard, the area affected, and the level of contamination. We provide a clear quote after initial assessment — no hidden charges.
In many cases, yes. Landlord insurance, building insurance, and commercial property policies often cover biohazard cleanup costs. We provide detailed invoices and documentation that insurers require for claims processing. Check your policy or speak to your insurer.
The main regulations are the Environmental Protection Act 1990, Hazardous Waste Regulations 2005, COSHH 2002, and the Health and Safety at Work Act 1974. These cover waste handling, chemical use, PPE requirements, and safe working practices. We hold all required certifications and provide full compliance documentation.
Completely. Unmarked vehicles, plain-clothed arrival, on-site PPE changeover. We don't advertise our presence at your property. This matters to landlords, property managers, and anyone dealing with a sensitive situation.
Our operatives are trained in biohazard handling, COSHH compliance, hazardous waste management, blood-borne pathogen protocols, and infection control. All are DBS-checked and carry current first aid certifications. SafeContractor approval covers our health and safety management system.
