An infectious outbreak in a home, care setting or workplace needs a fast, thorough response, and that is what we provide across the whole of the UK, 24 hours a day. Our technicians attend discreetly, assess the affected areas, and carry out touch-point disinfection and fogging to a clinical standard, whether the job is a single room or an entire facility. We are fully insured, our contaminated waste is handled by a licensed clinical-waste carrier, and every visit is arranged around the people who use the building. For a fast, confidential response, request a callback through our contact page or email us at [email protected].
What is infectious disease decontamination?
Infectious disease decontamination is the disinfection of a property after a confirmed or suspected outbreak of an infectious illness such as norovirus, Clostridium difficile, MRSA or influenza, combining manual touch-point disinfection with fogging to bring viral and bacterial loads down to a level safe for people to return to. It goes beyond routine cleaning.
Touch-point disinfection treats every handle, switch, rail and shared surface individually, while fogging disperses a fine disinfectant mist to reach areas that wiping alone can miss. Together, these methods target the surfaces and objects most likely to keep an infection spreading, which is what routine cleaning is not designed to do.
When is infectious disease decontamination needed?
Infectious disease decontamination is needed once an outbreak is confirmed or strongly suspected and ordinary cleaning has not stopped it spreading, in a household, a care setting or a shared workplace. Outbreaks do not respect property type, and we are contacted by:
- Families, after norovirus has moved through a household and normal cleaning has not stopped it recurring.
- Care home managers, when C. difficile or MRSA has been identified and the setting needs decontaminating in line with infection-control expectations.
- Landlords and letting agents, for a professional clean between tenancies where a previous occupant was seriously unwell.
- Employers and facilities teams, after a flu or norovirus outbreak has spread through an office, warehouse or shared workplace.
- Schools and other public buildings, when an illness has moved through pupils or staff and the premises need treating before people return.
In every case the aim is the same: to stop transmission and make the space safe to use again.
What standards and regulations apply to infectious disease decontamination?
Infectious disease decontamination is carried out under the Control of Substances Hazardous to Health Regulations 2002, with hospital-grade disinfectants chosen for proven efficacy against the organism involved, tested to standards such as BS EN 14476 for virucidal activity and BS EN 13697 for surface disinfection. Contaminated waste is removed under the Environmental Protection Act 1990 duty of care by a licensed clinical-waste carrier.
Our technicians wear protective equipment suited to the illness, including gloves, protective clothing and respiratory protection, and treat every touch point individually before fogging reaches what wiping can miss. In care settings we work in line with the infection-control expectations those environments are held to, and we ventilate and verify each treated area before it is handed back.
How is infectious disease decontamination carried out?
We carry out infectious disease decontamination in a set sequence that contains the affected area first, treats touch points and fogs the space, and verifies it is safe before anyone returns. The stages are consistent from job to job:
- Assess the property or facility, identifying the illness involved where known and mapping the areas and surfaces most at risk.
- Contain the affected area, restricting access so the infection cannot spread further while work is underway.
- Remove any contaminated items that cannot be safely disinfected, handling them as clinical waste throughout.
- Clean and disinfect all affected surfaces to a clinical standard, with particular attention to touch points such as door handles, light switches, taps, rails and shared equipment, followed by fogging where needed.
- Deodorise the treated areas as part of the same visit, addressing any lingering odour alongside the decontamination.
- Verify the area is safe before anyone returns, ventilating and checking that treated surfaces and rooms meet the standard required.
- Hand over the waste documentation, giving you a clear record of how contaminated material was removed and disposed of.
How much does infectious disease decontamination cost?
Infectious disease decontamination costs around £600 to £3,000 for most jobs, with a single room at the lower end and a whole facility or multi-room outbreak toward the upper end. These are indicative guide ranges to confirm at a free assessment, not fixed prices, because the size of the area, the illness involved and whether fogging is needed alongside touch-point disinfection all move the figure.
| Situation | Guide range | What affects it |
|---|---|---|
| Single room or dwelling | from £600 | Area treated, touch-point disinfection |
| Multi-room or facility outbreak | £1,000 to £3,000 | Fogging plus touch-point, size of site |
| Large or repeat decontamination | £3,000+ | Whole-site treatment, revisits |
The initial assessment is free and we agree a written price before any work begins. You can find more detail on how we cost different jobs on our biohazard cleaning cost page.
Is infectious disease decontamination covered by insurance?
Infectious disease decontamination is often covered under buildings, contents or commercial insurance policies, particularly where an outbreak has caused damage or where a policy includes specific cover for decontamination costs. We are happy to liaise directly with your insurer, provide the documentation they typically request, and help the claims process move as smoothly as possible. You can read more about how this usually works on our insurance claims page.
Why choose Biohazard Cleaning for infectious disease decontamination?
Biohazard Cleaning brings trained technicians, hospital-grade disinfectants, the right PPE and a fast nationwide response to every outbreak, so the job is done properly the first time rather than needing to be repeated. An infectious outbreak is stressful enough without wondering whether a surface clean has actually dealt with it, and ordinary household or office cleaning is not designed for the task.
Discretion matters too, particularly in care settings, schools and workplaces where reassuring residents, parents, staff or customers is as important as the clean itself. If the outbreak has involved bodily fluids or sewage contamination as well, our sewage cleanup and blood spill cleanup teams work alongside our decontamination technicians, and where sharps are found on site we can arrange sharps and needle removal as part of the same visit.
