How Far in Advance Must You Notify the HSE Before Licensed Asbestos Work?
If you’re planning licensed asbestos work, the answer is straightforward but non-negotiable: the Health & Safety Executive must be notified at least 14 days in advance of licensed work being carried out. This is one of the most critical compliance requirements under the Control of Asbestos Regulations, and getting it wrong can expose your organisation to serious legal and financial consequences.
Understanding exactly who needs to be notified, when, and what information must be included isn’t just a box-ticking exercise. It’s a legal duty that protects workers, the public, and the environment from one of the UK’s most persistent occupational health hazards.
The Legal Framework Behind Asbestos Notification Requirements
Asbestos management in the UK is governed primarily by the Control of Asbestos Regulations, which places clear duties on employers, building owners, and those in control of premises. These regulations sit under the broader umbrella of the Health and Safety at Work etc. Act, with detailed technical guidance provided through HSE’s HSG264.
The regulations divide asbestos work into three distinct categories, each carrying different notification and licensing obligations:
- Non-licensed work — lower-risk tasks that don’t require a licence or notification
- Notifiable non-licensed work (NNLW) — work that doesn’t require a licence but must still be notified to the relevant enforcing authority
- Licensed work — the highest-risk category, requiring both a licence and advance notification to the HSE
Each category has specific triggers, and misclassifying the work you’re undertaking is a common and costly mistake. If you’re unsure which category applies, professional asbestos testing is the essential first step before any decisions are made.
How Many Days in Advance of Licensed Work Being Carried Out Does the Health & Safety Executive Need to Be Notified?
Under the Control of Asbestos Regulations, the enforcing authority — which in most workplaces is the HSE — must be notified at least 14 days before licensed asbestos work begins. This is not a guideline or a recommendation. It is a legal requirement.
The 14-day window exists to allow the HSE to review the planned work, arrange inspections if necessary, and ensure that appropriate safety measures are in place before any high-risk asbestos disturbance takes place.
There is an exception to the 14-day rule: in cases of genuine emergency — for example, where urgent structural repairs are required following unexpected damage — the HSE may accept shorter notice. However, this exception is narrow and must not be used as a workaround for poor planning. The expectation is that notification happens as early as possible even in emergency situations.
What Counts as Licensed Asbestos Work?
Licensed work is required when the activity involves higher-risk asbestos-containing materials (ACMs) or when the work is likely to exceed the control limit for airborne asbestos fibres. Specific types of work that typically require a licence include:
- Removal of asbestos insulation (lagging) from pipes, boilers, and vessels
- Removal of asbestos insulating board (AIB)
- Work on sprayed asbestos coatings
- Any work where the exposure is not sporadic and of low intensity
- Work that cannot be clearly classified as non-licensed or NNLW
Only contractors holding a current asbestos licence issued by the HSE can carry out this type of work. Licences are issued for either one or three years and must be renewed before expiry.
Who Is the Enforcing Authority?
In most workplaces, the enforcing authority for licensed asbestos work is the HSE. However, for premises where local authorities act as the enforcing authority — such as certain retail, hospitality, and leisure premises — notification goes to the relevant local authority environmental health department instead.
In Scotland, the Health and Safety Executive for Great Britain still applies, but some environmental aspects may involve SEPA (the Scottish Environment Protection Agency). Always confirm the correct enforcing authority for your specific premises and work type before submitting your notification.
What Information Must Be Included in Your Notification?
A notification isn’t simply a heads-up call. It must contain specific information to be valid. The HSE requires the following details as part of a compliant notification for licensed asbestos work:
- The name and address of the person or organisation carrying out the work
- The address and location of the site where the work will take place
- A brief description of the type of asbestos work to be carried out
- The type and form of asbestos involved (e.g., asbestos insulating board, lagging)
- The maximum number of workers likely to be involved
- The start date and expected duration of the work
- The method to be used for the work
- The measures taken to limit workers’ exposure to asbestos
Incomplete notifications can delay the start of work and may be treated as non-compliant. It’s worth having your licensed contractor prepare this documentation as part of their pre-work planning — it should be standard practice for any reputable firm.
Notifiable Non-Licensed Work: Different Rules, Same Seriousness
Not all notifiable asbestos work requires a licence. Notifiable non-licensed work (NNLW) sits in the middle tier — it doesn’t need a licensed contractor, but it does require notification to the enforcing authority before work starts.
NNLW typically involves materials like asbestos cement products or textured decorative coatings (such as Artex), where the work is short-duration and the fibres are less likely to become airborne in significant quantities. However, the risks are still real, and the regulatory obligations reflect that.
What Employers Must Do for NNLW
For notifiable non-licensed work, employers must:
- Notify the relevant enforcing authority before work begins (no specific minimum number of days is prescribed, but notification must be made in advance)
- Conduct a risk assessment specific to the work
- Ensure workers have received adequate training and hold an asbestos awareness certificate at minimum
- Keep health records and arrange medical surveillance for workers regularly involved in NNLW
- Maintain records of the work carried out
Medical surveillance for NNLW workers must be carried out by an employment medical adviser or appointed doctor, and records must be kept for 40 years. This reflects the long latency period of asbestos-related diseases.
How Does NNLW Differ from Non-Licensed Work?
Non-licensed work — sometimes referred to as minor, short-duration work — involves the lowest-risk asbestos activities and carries no notification requirement. This might include tasks where a single worker disturbs a small quantity of asbestos cement for less than one hour, or where a team of workers collectively spends fewer than two hours on such tasks within a seven-day period.
Even for non-licensed work, however, a risk assessment must still be carried out, appropriate PPE must be worn, and the work must be planned to minimise fibre release. The absence of a notification requirement does not mean the absence of duty of care.
The Consequences of Failing to Notify
The penalties for non-compliance with asbestos notification requirements are significant. The HSE takes enforcement seriously, and rightly so — asbestos-related diseases remain a leading cause of occupational death in the UK.
Employers who fail to notify the HSE before carrying out licensed asbestos work can face:
- Prohibition notices stopping all work immediately
- Improvement notices requiring remedial action within a set timeframe
- Prosecution, with fines that can be unlimited in the Crown Court
- In serious cases, imprisonment for individuals found responsible
Beyond the legal penalties, there are significant reputational and insurance implications. Many insurers will not cover claims arising from asbestos work carried out without proper notification and licensing, leaving businesses exposed to potentially enormous civil liability.
The HSE actively inspects licensed asbestos removal sites, and unlicensed contractors or those operating without notification are a known enforcement priority. Don’t assume that because a site is small or the work is brief, it won’t attract scrutiny.
Asbestos Disposal Regulations: What Happens After the Work Is Done
Notification requirements don’t end when the asbestos has been removed. The disposal of asbestos waste is separately regulated, and there are additional authorities and obligations to consider.
Asbestos waste is classified as hazardous waste under UK environmental regulations. This means it must be:
- Double-wrapped in heavy-duty polythene sheeting and sealed securely
- Clearly labelled with appropriate hazard warnings identifying the contents as asbestos
- Transported only by a registered waste carrier
- Disposed of only at a licensed hazardous waste facility
- Accompanied by a consignment note (hazardous waste consignment note) throughout its journey from site to disposal
The Environment Agency (in England), Natural Resources Wales, SEPA (in Scotland), and the NIEA (in Northern Ireland) are the relevant environmental regulators for asbestos waste disposal. Producers of hazardous waste — including those generating asbestos waste — have notification obligations to these bodies as well.
For professional asbestos removal that handles all disposal documentation correctly, working with an experienced and licensed contractor is essential. Cutting corners on paperwork at the disposal stage is just as legally risky as failing to notify the HSE before the work begins.
Employer and Employee Responsibilities Under the Regulations
The Control of Asbestos Regulations places duties on both employers and employees. Understanding these responsibilities is critical for anyone managing or working on premises where asbestos may be present.
Employer Duties
- Identify and assess all asbestos-containing materials in the premises
- Produce and maintain an asbestos management plan
- Ensure only licensed contractors carry out licensable work
- Notify the HSE at least 14 days before licensed work begins
- Provide adequate training for all workers who may encounter asbestos
- Ensure appropriate PPE is provided and used correctly
- Arrange medical surveillance where required
- Keep records of all asbestos work, including air monitoring results
Employee Rights and Protections
Workers have the right to a safe working environment, which includes being informed about the presence of asbestos in their workplace. Employees involved in asbestos work must receive appropriate training — not just a one-off session, but refresher training at regular intervals to keep their knowledge current.
Workers are also entitled to medical surveillance if they carry out NNLW or licensed work regularly. If you believe your employer is failing to meet their obligations under the Control of Asbestos Regulations, you can contact the HSE Concerns team directly.
The Role of Asbestos Surveys in Compliance
Before any notification can be made, you need to know what you’re dealing with. An asbestos survey is the foundation of all compliant asbestos management. Without one, you cannot accurately classify the work, identify the materials involved, or prepare the information required for HSE notification.
There are two main types of survey:
- Management survey — identifies and assesses ACMs that could be disturbed during normal occupation and routine maintenance
- Refurbishment and demolition survey — a more intrusive survey required before any refurbishment or demolition work, designed to locate all ACMs in the affected area
For anyone undertaking asbestos testing ahead of planned works, using a UKAS-accredited laboratory and a qualified surveyor is not optional — it’s a requirement under HSG264.
Supernova Asbestos Surveys provides both management and refurbishment surveys across the UK, with results delivered promptly so that your project timeline isn’t delayed. Whether you need an asbestos survey in London, an asbestos survey in Manchester, or an asbestos survey in Birmingham, our nationwide network of qualified surveyors means you’re never far from expert support.
Practical Steps Before Licensed Asbestos Work Begins
If you’re managing a property or project where licensed asbestos work is required, here’s a practical checklist to keep you compliant:
- Commission a refurbishment and demolition survey — before any intrusive work begins, you need a full picture of what ACMs are present
- Engage a licensed asbestos contractor — verify their HSE licence is current and covers the type of work required
- Prepare the notification — work with your contractor to compile all required information for the HSE notification
- Submit the notification at least 14 days before work starts — build this into your project programme from the outset
- Confirm the correct enforcing authority — HSE or local authority, depending on your premises type
- Ensure an asbestos management plan is in place — this should be updated to reflect the planned work
- Plan for waste disposal — arrange a licensed waste carrier and confirm the receiving facility is licensed for hazardous waste
- Conduct air monitoring — during and after the work to verify fibre levels are within acceptable limits
- Obtain a clearance certificate — a four-stage clearance procedure, including independent air testing, is required before the enclosure is dismantled
Each of these steps has regulatory weight behind it. Missing any one of them doesn’t just create a compliance gap — it can put lives at risk.
Frequently Asked Questions
How many days in advance of licensed work being carried out does the Health & Safety Executive need to be notified?
The HSE must be notified at least 14 days before licensed asbestos work begins. This is a legal requirement under the Control of Asbestos Regulations. In genuine emergencies, shorter notice may be accepted, but this exception is narrow and should not be relied upon for planned projects.
What happens if you fail to notify the HSE before licensed asbestos work?
Failure to notify the HSE can result in prohibition notices stopping the work immediately, improvement notices, prosecution, and unlimited fines in the Crown Court. In serious cases, individuals responsible can face imprisonment. The HSE actively enforces compliance on licensed asbestos removal sites.
Does notifiable non-licensed work (NNLW) also require advance notification?
Yes. NNLW must be notified to the relevant enforcing authority before work begins, although there is no prescribed minimum number of days as there is for licensed work. Employers carrying out NNLW must also maintain health records and arrange medical surveillance for workers regularly involved in this type of work.
Who is responsible for notifying the HSE — the building owner or the contractor?
The licensed contractor carrying out the work is responsible for submitting the notification to the HSE. However, building owners and employers who commission the work have a duty to ensure that a licensed contractor is used and that all regulatory requirements — including notification — are met. Both parties share responsibility for compliance.
Is asbestos disposal separately regulated from the removal work itself?
Yes. Asbestos waste is classified as hazardous waste and is subject to separate environmental regulations. It must be double-wrapped, clearly labelled, transported by a registered waste carrier, and disposed of at a licensed hazardous waste facility. Consignment notes must accompany every load. The Environment Agency and its devolved equivalents regulate this aspect of asbestos management.
