HVAC & Ductwork Cleaning Risk Assessment — Generated Instantly for £29
Describe the system — ducting layout, access method, building age and any confined space or height elements. We generate a fully written, UK-compliant HVAC and ductwork cleaning risk assessment covering confined space entry, respiratory hazards, asbestos potential and working at height in minutes.
Used by ventilation hygiene contractors, duct cleaning specialists and facilities management teams across the UK
🌀 Entering the ducting itself, not just cleaning from access points? Mention it — we'll include confined space entry procedures, atmospheric monitoring, rescue arrangements and permit-to-work requirements under the Confined Spaces Regulations 1997.
Legal requirements for HVAC and ductwork cleaning
Where cleaning requires physical entry into ducts, risers or plenums, the Confined Spaces Regulations 1997 apply. Regulation 4 prohibits entry into a confined space where the work can reasonably be done another way, and where entry is unavoidable, requires a safe system of work covering atmospheric testing, communication, and emergency rescue arrangements. Many commercial HVAC systems meet the legal definition of a confined space because of restricted access and the risk of a build-up of dust, fumes or depleted oxygen.
Exposure to accumulated dust, debris and microbiological growth inside ductwork is controlled under the Control of Substances Hazardous to Health Regulations 2002 (COSHH), which requires an assessment of exposure and selection of suitable respiratory protective equipment. Where ceiling voids, plant rooms or roof-mounted air handling units must be accessed, the Work at Height Regulations 2005 require that work is properly planned, appropriately supervised and carried out using suitable equipment.
In buildings constructed or refurbished before 2000, ductwork insulation, lagging and sealants may contain asbestos. The Control of Asbestos Regulations 2012 place a duty on those managing non-domestic premises to presume materials contain asbestos unless there is evidence otherwise, and disturbance of suspect material during cleaning must be avoided until a survey has been carried out. The Health and Safety at Work etc. Act 1974 and the Management of Health and Safety at Work Regulations 1999 require a suitable and sufficient written risk assessment covering all of these hazards before work begins.
How it works
1. Describe the job
Tell us the system type, access method, building age, whether duct entry or rotary brush equipment will be used, and any confined space or height elements. See our guide to when you need a risk assessment if you're unsure what to include.
2. Let the app take the strain
Anyrisks produces a fully written, UK-compliant HVAC and ductwork cleaning risk assessment referencing the Confined Spaces Regulations 1997, COSHH 2002, the Work at Height Regulations 2005 and the Control of Asbestos Regulations 2012 where relevant.

Works for
From office supply ducts to commercial kitchen extract systems, Anyrisks covers every type of ventilation hygiene job.
What customers say
"We go into ducts that most cleaning templates don't even consider. Anyrisks picked up the confined space angle straight away and built the whole entry procedure into the assessment."
Dave Richardson
Ventilation hygiene technician, Leeds
"Half our jobs are in buildings from the 80s and 90s. Having the asbestos presumption duty flagged automatically has saved us from a few awkward conversations with clients."
Michelle Osei
Duct cleaning contractor, Birmingham
"We use negative pressure rigs on every kitchen extract job. The assessment covered containment and HEPA filtration properly, not just a generic COSHH line like most templates give you."
Tom Featherstone
Kitchen extract specialist, Manchester

Frequently asked questions
What hazards must an HVAC and ductwork cleaning risk assessment cover?
It must cover confined space entry into ducting under the Confined Spaces Regulations 1997, respiratory exposure to dust, debris and microbiological growth under COSHH 2002, working at height to access ceiling voids and plant rooms under the Work at Height Regulations 2005, mechanical risks from rotary brush and whip equipment, and the potential presence of asbestos insulation board or lagging in systems installed before 2000.
Is duct cleaning classed as confined space work?
Many ductwork sections, risers, plenums and air handling units meet the legal definition of a confined space under the Confined Spaces Regulations 1997 because of restricted access, poor natural ventilation and the risk of engulfment by dust or fume build-up. If entry is required, a specific confined space risk assessment and safe system of work — including atmospheric testing, rescue arrangements and a permit to work — is needed, not just a general cleaning assessment.
How does Anyrisks handle the asbestos risk in older duct systems?
Describe the building age and any known asbestos survey information in your job description. If the system was installed before 2000, the assessment will reference the duty under Regulation 4 of the Control of Asbestos Regulations 2012 to presume materials contain asbestos unless proven otherwise, and will recommend a refurbishment and demolition asbestos survey before any invasive cleaning begins.
Does the assessment cover biological contamination from HVAC systems?
Yes — ductwork and air handling units can harbour mould, bacteria and, in cooling systems, Legionella. The assessment references COSHH 2002 for biological agents and includes controls such as RPE selection, decontamination procedures and waste disposal, tailored to the system type you describe.
Can it cover negative pressure containment systems used during cleaning?
Yes — mention that negative pressure or vacuum containment equipment will be used and the assessment will include controls around HEPA filtration, containment integrity checks, and preventing contaminated air or debris escaping into occupied areas during the clean.
Is TR19 referenced in the assessment?
Where relevant, the assessment reflects good practice guidance from BESA TR19, the recognised industry standard for internal cleanliness of ventilation systems, alongside the statutory duties under the Health and Safety at Work etc. Act 1974 and COSHH 2002.
Do I need a separate risk assessment for each site?
Yes, in principle — duct layout, access routes, system age and building use vary between sites. Generate a new assessment for each job by describing the specific system and site conditions; it only takes a couple of minutes and ensures the controls match the actual hazards present.
How quickly can I get a risk assessment for a duct cleaning job?
Under 2 minutes. Describe the system, access method and any confined space, height or asbestos considerations, and Anyrisks generates a complete, regulation-referenced risk assessment ready to download as PDF and Word.
