Asbestos Awareness Declaration

The Asbestos Awareness Declaration confirms that all workers on site have received asbestos awareness training and understand the risks, types of ACMs they may encounter, and the emergency procedure if asbestos is suspected. It records individual sign-offs and training dates. Asbestos awareness is mandatory for anyone whose work could foreseeably disturb ACMs.

Training duty	Control of Asbestos Regulations 2012 (CAR 2012) Regulation 10 requires employers to ensure that adequate information, instruction, and training is given to any employee who is liable to be exposed to asbestos, or who supervises such employees. Training must be refreshed annually.
Awareness training	Category A awareness training is the minimum standard for any worker whose activities could foreseeably disturb asbestos-containing materials (ACMs). It does not qualify the holder to work with asbestos — it trains them to recognise ACMs and avoid disturbance.
PC duty	CDM 2015 Regulation 8(4) requires the Principal Contractor to satisfy themselves that every person carrying out construction work has the skills, knowledge, training, and experience necessary for the work. This includes verifying asbestos awareness training for all subcontractors working in buildings that may contain ACMs.
What it confirms	The declaration confirms five things: (1) the asbestos register has been received and reviewed, (2) the subcontractor is aware of identified ACMs relevant to their work area, (3) operatives hold current Category A awareness training, (4) emergency procedures for suspected ACM disturbance are understood, and (5) the subcontractor will not disturb any known or suspected ACMs.
Not a licence	This declaration confirms awareness only. It does not constitute permission to work with, remove, encapsulate, or disturb asbestos in any form. Any work involving deliberate disturbance of ACMs requires a licensed asbestos removal contractor (LARC) or, for lower-risk materials, appropriately trained operatives working under a task-specific plan of work.

1. Why an Asbestos Awareness Declaration Is Required

Any building constructed or refurbished before the year 2000 may contain asbestos-containing materials (ACMs). Under the Control of Asbestos Regulations 2012, the duty holder (typically the building owner or occupier for non-domestic premises) is required to manage asbestos in the building and to provide information about the location and condition of ACMs to anyone who might disturb them. On construction projects governed by CDM 2015, this duty is supplemented by the Principal Contractor's obligation to ensure that every subcontractor working on site understands where ACMs are located and how to avoid disturbing them.

The Asbestos Awareness Declaration is the formal record that a subcontractor has received the asbestos register, has been briefed on the location of ACMs relevant to their work area, confirms that their operatives hold current Category A awareness training, understands the emergency procedure in the event of suspected disturbance, and has committed in writing not to disturb any known or suspected ACMs. Without this declaration, the Principal Contractor has no documented evidence that the subcontractor has been properly informed — and in the event of an incident, the absence of such documentation will be treated as a significant failing by the HSE.

The declaration is not a one-off administrative formality. It must be obtained from every subcontractor before they begin work on site, and it must be refreshed whenever the asbestos register is updated, whenever new ACMs are discovered during the course of the works, or whenever the subcontractor's workforce changes. On refurbishment and demolition projects, where the risk of encountering concealed ACMs is significantly higher, the declaration takes on particular importance because it records the subcontractor's acknowledgement that an R&D survey has been completed and that they understand the specific ACM risks associated with their scope of work.

The declaration must reference the actual asbestos register

A generic asbestos awareness declaration that does not reference the specific asbestos register for the building or site is inadequate. The declaration must confirm that the subcontractor has received and reviewed the actual register — identified by its reference number, date, and the name of the surveyor who produced it. This ensures the subcontractor has been briefed on the specific ACMs present in their work area, not simply given a general awareness of asbestos risks. The HSE will examine whether the declaration is linked to the actual register during any investigation.

2. What the Declaration Should Confirm

The declaration should be a structured document that covers all the essential elements required to demonstrate compliance with CAR 2012 Regulation 10 and CDM 2015 Regulation 8(4). Each field serves a specific legal or practical purpose, and omitting any of them weakens the evidentiary value of the document. The following table sets out the fields that a compliant Asbestos Awareness Declaration should include.

Field	Purpose and Content
Organisation details	Full name, registered address, and contact details of the subcontractor organisation. This identifies the legal entity making the declaration and ensures accountability can be traced to a specific company, not just an individual operative.
Works scope	A clear description of the subcontractor's scope of work on the project, including the specific areas of the building or site where they will be working. This is critical because the declaration must confirm awareness of ACMs relevant to their work area, not the entire building.
Register received	Confirmation that the subcontractor has received a copy of the asbestos register (or the relevant extract relating to their work area), identified by reference number, date of issue, and the name of the surveyor or surveying company. This creates a direct link between the declaration and the actual register.
ACM awareness	Confirmation that the subcontractor has reviewed the register, understands the locations and types of ACMs identified in or near their work area, and has communicated this information to all operatives who will be carrying out work on site. This extends the duty of awareness from the subcontractor's management to the individual operatives.
Training status	Confirmation that all operatives who will work on site hold current Category A asbestos awareness training (or higher). Training must have been refreshed within the last 12 months. The declaration should state the training provider and the date of the most recent training for each operative, or confirm that training records are available for inspection.
Emergency procedure	Confirmation that the subcontractor and their operatives understand the emergency procedure to follow if suspected ACMs are disturbed or discovered during the course of the works. The procedure typically requires: stop work immediately, evacuate the area, prevent others from entering, do not attempt to clean up, notify the site manager and Principal Contractor immediately, and await instruction from a competent asbestos professional.
Non-disturbance commitment	A clear statement that the subcontractor will not cut, drill, sand, break, remove, or otherwise disturb any known or suspected ACMs. If their work requires disturbance of ACMs, this must be referred to the Principal Contractor and carried out by appropriately licensed or trained personnel under a separate plan of work.
Signature and date	Signature of an authorised representative of the subcontractor organisation (not just an individual operative), printed name, position, and the date of signing. This creates a legally binding declaration. The PC should countersign to confirm that the register was provided and the briefing was given.

3. Common Mistakes

Using a one-size-fits-all declaration that does not reference the specific register

A generic declaration that simply states the subcontractor is "aware of asbestos risks" without referencing the actual asbestos register for the building or site is inadequate. The declaration must be project-specific and must confirm receipt of the actual register, identified by reference number, date, and surveyor. A generic template used across multiple projects without amendment demonstrates a failure to engage with the specific risks present on each site. The HSE will treat this as evidence of a tick-box approach rather than genuine risk management.

Not verifying that training is current

CAR 2012 Regulation 10 requires asbestos awareness training to be refreshed annually. A declaration that confirms operatives "have received asbestos awareness training" without verifying that the training was completed within the last 12 months is insufficient. The Principal Contractor should request training certificates or records showing the date of the most recent training for each operative. Out-of-date training is equivalent to no training at all for compliance purposes, and the PC will be held responsible for allowing inadequately trained operatives to work in areas containing ACMs.

Not briefing new subcontractors or operatives who arrive mid-project

The declaration process is not a one-off event at the start of the project. When new subcontractors are appointed or existing subcontractors introduce new operatives to site, each must receive the asbestos register briefing and complete a declaration before starting work. This is commonly overlooked on longer projects where multiple subcontractors come and go. A subcontractor operative who arrives mid-project and begins work without being briefed on ACM locations represents an immediate and serious risk of accidental disturbance.

Assuming the declaration protects the Principal Contractor from liability

The declaration is evidence that the PC has fulfilled their duty to inform, but it does not transfer liability. If a subcontractor subsequently disturbs ACMs, the PC will be investigated by the HSE for the adequacy of their overall asbestos management arrangements — including whether the briefing was meaningful, whether the register was adequate, whether controls were in place to prevent disturbance, and whether the PC was monitoring the subcontractor's work. The declaration is one element of a comprehensive asbestos management system, not a standalone defence.

Not explaining the emergency procedure in practical terms

A declaration that states the subcontractor "understands the emergency procedure" is meaningless if the procedure was never explained in practical terms. The briefing must cover exactly what to do: stop work, evacuate the immediate area, prevent anyone from entering, do not attempt to clean up, contact the site manager by name and phone number, and wait for a competent asbestos professional to assess the situation. The procedure must be rehearsed verbally during the briefing, not simply handed over as a written document. Operatives who cannot recall the procedure when questioned by the HSE undermine the credibility of the entire declaration process.

4. Related Documents

Document	Relationship
D1 — Asbestos Management Survey	The management survey identifies the location, extent, and condition of ACMs in the building for ongoing management purposes. The results of the management survey feed directly into the asbestos register, which is the document provided to subcontractors as part of the awareness declaration process.
D2 — Asbestos Refurbishment and Demolition Survey	For refurbishment or demolition projects, the R&D survey provides more detailed and intrusive identification of ACMs. The declaration must reference the R&D survey findings where applicable, ensuring the subcontractor is aware of concealed ACMs that will be exposed by their work.
D3 — Asbestos Register	The register is the core document that the declaration references. It records all known ACMs, their location, condition, and the management action assigned to each. The declaration confirms the subcontractor has received and reviewed the register relevant to their work area.
D4 — Asbestos Management Plan	The management plan sets out the overall strategy for managing ACMs in the building, including re-inspection schedules, procedures for planned maintenance, and emergency response procedures. The awareness declaration is one element of the management plan's implementation for construction projects.
D6 — Asbestos Removal Plan	Where ACMs need to be removed before or during the subcontractor's work, the removal plan governs that work. The declaration confirms the subcontractor understands they must not disturb ACMs themselves and that any necessary removal will be carried out by a licensed contractor under a separate plan of work.
C10 — COSHH Assessment: Asbestos	The COSHH assessment for asbestos covers the specific health risks, exposure controls, RPE requirements, and monitoring arrangements for any work that may generate asbestos fibre release. The awareness declaration complements the COSHH assessment by confirming the subcontractor understands the risks even where they are not directly working with ACMs.
B15 — RAMS: Demolition	Demolition method statements must confirm that asbestos awareness declarations have been obtained from all subcontractors and that the R&D survey has been completed. The declaration forms part of the evidence pack that demonstrates asbestos risks have been addressed before demolition work begins.

5. Frequently Asked Questions

What level of asbestos training is required for the declaration?▾

The minimum requirement is Category A asbestos awareness training, as defined in the HSE's Approved Code of Practice L143. Category A training covers the properties of asbestos, health effects, the types of materials likely to contain asbestos, the locations where ACMs are commonly found, how to avoid disturbing ACMs, and the emergency procedure if disturbance is suspected. This is the baseline for any worker whose activities could foreseeably bring them into contact with ACMs, even if they are not working directly with asbestos. Category B (non-licensed work) and Category C (licensed work) training are higher levels required for operatives who will deliberately disturb ACMs. The declaration for awareness purposes requires Category A as the minimum.

Is it sufficient for a subcontractor to provide their own asbestos awareness certification without completing the project-specific declaration?▾

No. A subcontractor's own training certification demonstrates that their operatives have received asbestos awareness training, but it does not demonstrate that they have been briefed on the specific ACMs present on this particular site. The declaration serves a different purpose from the training certificate. The training certificate confirms general competence; the declaration confirms site-specific awareness. Both are required. A subcontractor who holds valid Category A training but has not been briefed on the specific ACM locations in the building where they are working represents just as great a risk as an untrained operative, because they do not know which materials to avoid.

Is a declaration required on domestic projects?▾

CDM 2015 applies to all construction work, including domestic projects, although the client duties differ. For domestic projects, the contractor or principal contractor must still manage asbestos risks. If the property was built before 2000, asbestos may be present and the contractor should obtain a management survey or R&D survey as appropriate. While there is no formal "duty holder" obligation under CAR 2012 Regulation 4 for domestic premises, the employer's duty under Regulation 10 to ensure adequate training still applies. In practice, a declaration should be obtained from any subcontractor working in a domestic property that may contain ACMs, because the contractor remains responsible for ensuring operatives are aware of the risks and know how to avoid disturbing ACMs.

What happens if an operative begins work without a declaration in place?▾

If an operative begins work without having signed the declaration, the Principal Contractor has no documented evidence that the operative has been briefed on ACM locations. If the operative then disturbs ACMs — or if the HSE inspects the site and finds operatives working without declarations — the PC will face enforcement action for failing to discharge their duty under CDM 2015 Regulation 8(4) and for failing to ensure adequate information was provided under CAR 2012 Regulation 10. In practical terms, the operative should be removed from the work area immediately, briefed on the asbestos register, asked to complete the declaration, and only then permitted to resume work. The incident should be recorded as a near-miss in the project's health and safety file.
