The ASB5 Form: What Every Contractor Must Know Before Licensable Asbestos Work Begins
If you are planning licensable asbestos work on a UK construction site, the ASB5 form is not optional — it is a legal requirement under the Control of Asbestos Regulations. Miss the notification deadline, submit incorrect information, or skip the process entirely, and you are looking at prosecution, enforcement action, and reputational damage that is very hard to recover from.
This post covers what the ASB5 form is, when you need it, how to complete it correctly, and the wider legal framework it sits within. Whether you are a contractor, employer, or site manager, understanding this form is fundamental to operating lawfully with asbestos in the UK.
What Is the ASB5 Form?
The ASB5 form is the official notification document that licensed contractors must submit to the relevant enforcing authority before carrying out licensable asbestos work. The Control of Asbestos Regulations places a clear duty on anyone undertaking licensable work with asbestos to notify the appropriate authority in advance — the ASB5 form is how that notification is made.
The form captures key details about the planned work: where it is happening, what type of asbestos is involved, how long the job will take, and what control measures will be in place to protect workers and others on site.
One distinction matters enormously here: the ASB5 form is a notification, not a permit. Submitting it does not mean you have received approval to proceed. It means the enforcing authority has been informed — and they may still intervene if something is not in order.
The enforcing authority receiving the ASB5 form will typically be either the Health and Safety Executive (HSE) or the relevant local authority, depending on the nature of the premises and the type of work being carried out. If you are unsure which body has jurisdiction over your site, the HSE website provides clear guidance on this.
When Is the ASB5 Form Required?
Not every asbestos-related task triggers the notification requirement. The ASB5 form applies specifically to licensable work — a defined category under the Control of Asbestos Regulations.
Work becomes licensable when it involves any of the following:
- Removing or disturbing sprayed asbestos coatings, such as limpet asbestos
- Working with asbestos pipe lagging or thermal insulation
- Disturbing loose-fill asbestos insulation
- Any task where exposure to asbestos fibres cannot be reduced to a low level and is not sporadic or low intensity
- Work that exceeds two hours of asbestos exposure for any individual within a seven-day period
If your work falls into any of these categories, you need a licence — and you need to submit the ASB5 form at least 14 days before work begins. That deadline is firm. There is no grace period, and submitting late is itself a breach of the regulations.
What About Non-Licensable Work?
Some asbestos tasks are non-licensable but still carry notification obligations. This is known as notifiable non-licensed work (NNLW). While the ASB5 form is specifically tied to licensable work, contractors carrying out NNLW have separate notification and record-keeping duties under the same regulations.
Do not assume that because work is non-licensable you have no obligations at all. The regulatory framework is layered, and ignorance of the distinction is not a defence.
How to Complete the ASB5 Form
The ASB5 form is available from the HSE and must be completed accurately and in full. Submitting incomplete or incorrect information is treated seriously — it undermines the purpose of the notification system and can still result in enforcement action even if the work itself was carried out safely.
Here is what the form requires:
- Name and address of the contractor — the licensed company carrying out the work
- Licence number — your current asbestos removal licence issued by the HSE
- Location of the work — full address of the site where licensable asbestos work will take place
- Description of the work — the type of asbestos-containing materials (ACMs) involved and the nature of the task
- Type of asbestos — where known, identify whether the material contains chrysotile, amosite, crocidolite, or another fibre type
- Estimated duration — when the work will start and how long it is expected to last
- Maximum number of workers — the highest number of people likely to be working with asbestos at any one time
- Control measures — a summary of the precautions being taken to protect workers and others on site
Once completed, the form is submitted to the enforcing authority — either the HSE or the local authority. Build form submission into your project planning from the outset. Treating it as an afterthought is how contractors end up missing the 14-day deadline.
Submitting the Form in Practice
The ASB5 form can be submitted by post or electronically. Whichever method you use, keep a copy of the submitted form and any acknowledgement you receive.
If the enforcing authority raises questions or concerns, a clear paper trail showing when and how you notified them is essential. Do not rely on verbal confirmation or assume that silence from the authority means everything is in order. Document everything.
The Wider Legal Framework: Where the ASB5 Form Fits
The ASB5 form does not exist in isolation. It is one part of a broader set of legal obligations that contractors must meet under the Control of Asbestos Regulations and supporting HSE guidance, including HSG264.
Before any licensable work takes place, contractors should already have:
- Confirmed the presence, location, type, and condition of all ACMs through a suitable asbestos survey
- Prepared a written plan of work detailing how the job will be carried out safely
- Ensured all workers are appropriately trained and medically fit for asbestos work
- Arranged for air monitoring and clearance testing as required
- Established proper enclosures, decontamination facilities, and waste disposal procedures
The ASB5 form notification is the point at which you formally tell the enforcing authority this work is happening. Everything else — the survey, the plan of work, the trained team — should already be in place before you submit it.
The Role of Asbestos Surveys Before Licensable Work
You cannot complete the ASB5 form accurately without knowing what you are dealing with. Identifying the type of asbestos, its location, and its condition requires a professional survey — not guesswork.
Before licensable asbestos work begins, a refurbishment survey should be carried out to identify and fully characterise all ACMs in the areas to be disturbed. This is not optional — it is the foundation of everything that follows, including accurate completion of the ASB5 form.
For ongoing management of asbestos in occupied buildings, a management survey provides the baseline register of ACMs that duty holders are required to maintain. This underpins any future decisions about whether licensable work is needed and what the ASB5 form should contain.
Where ACMs have previously been identified and managed, a re-inspection survey ensures the condition of those materials is kept up to date — vital information before any contractor disturbs them. Asbestos materials that were stable when first recorded may have deteriorated significantly by the time work begins.
When You Are Unsure About a Material
If you encounter a suspect material on site and are unsure whether it contains asbestos, do not disturb it. Asbestos testing by a UKAS-accredited laboratory is the only reliable way to confirm whether a material contains asbestos fibres — and what type.
For initial screening of a suspect material before commissioning a full survey, an asbestos testing kit can help identify whether professional assessment is needed. However, for any work that may involve disturbance of ACMs, a full professional survey is always the appropriate route.
Asbestos Risks in the UK Construction Industry
The construction industry remains one of the sectors most affected by asbestos-related disease in the UK. Tradespeople working in roofing, plumbing, demolition, and general building maintenance are among those at greatest risk — particularly when working on properties built before 2000, when asbestos use was finally banned in the UK.
Common asbestos-containing materials found on construction sites include:
- Asbestos cement sheets and panels
- Pipe lagging and thermal insulation
- Sprayed coatings on structural steelwork and ceilings
- Floor tiles and associated adhesives
- Textured decorative coatings such as Artex
- Fireproofing materials and protective coatings
- Insulating board used in partition walls and ceiling tiles
Many of these materials are not immediately obvious. That is why surveys are essential before work begins — not just to satisfy legal requirements, but to protect the people doing the work.
Asbestos-related diseases — including mesothelioma, asbestosis, and asbestos-related lung cancer — can take decades to develop after exposure. Workers exposed to asbestos fibres today may not show symptoms for 15 to 60 years. The regulatory framework, including the ASB5 form notification requirement, exists precisely because the risks are so long-lasting and so serious.
Consequences of Not Submitting the ASB5 Form
The consequences of failing to notify the enforcing authority are not theoretical. Carrying out licensable asbestos work without a valid licence is a criminal offence. Failing to submit the ASB5 form, or submitting it late, compounds that breach.
Enforcement action can include:
- Prohibition notices stopping work immediately
- Improvement notices requiring remedial action
- Prosecution under the Health and Safety at Work Act and the Control of Asbestos Regulations
- Significant financial penalties and, in serious cases, custodial sentences
Beyond the regulatory penalties, the reputational damage to a licensed contractor found operating outside the rules can be severe. Clients, principal contractors, and main contractors all carry out due diligence — a prosecution or enforcement notice is extremely difficult to explain away when tendering for future work.
If asbestos removal is being carried out without proper notification and oversight, the consequences extend well beyond the contractor. Workers, building occupants, and neighbouring sites can all be put at risk. The notification system exists to prevent exactly this.
Contractor Responsibilities Beyond the ASB5 Form
Submitting the ASB5 form is a legal minimum, not a complete compliance strategy. Contractors working with asbestos have a broad set of duties that run throughout a project.
Before Work Starts
- Obtain and review any existing asbestos register or survey reports for the site
- Commission a refurbishment survey if one has not been carried out
- Prepare a written plan of work in line with HSG264 requirements
- Ensure all operatives hold the relevant training certificates and are medically fit
- Submit the ASB5 form at least 14 days before work begins
During the Work
- Implement the control measures set out in the plan of work
- Carry out regular air monitoring to verify fibre levels remain within acceptable limits
- Maintain proper decontamination procedures for workers leaving the work area
- Segregate and label all asbestos waste correctly for licensed disposal
After the Work
- Arrange a four-stage clearance procedure before the enclosure is removed
- Provide a certificate of reoccupation confirming the area is safe
- Update the site asbestos register to reflect materials that have been removed
- Retain all records, including the ASB5 form submission, for the required period
Other Safety Obligations That Run Alongside Asbestos Compliance
Asbestos management does not exist in a vacuum. For many properties — particularly commercial buildings, schools, and housing in multiple occupation — asbestos compliance runs alongside other statutory safety requirements.
A fire risk assessment is a legal requirement for most non-domestic premises, and for some residential buildings. Coordinating your asbestos survey and fire risk assessment ensures that both obligations are met efficiently, without duplication of effort or gaps in your safety management documentation.
If you are managing a large site or a portfolio of properties, having a single point of contact for both asbestos and fire safety compliance can significantly reduce the administrative burden and ensure nothing falls through the cracks.
Regional Considerations: Asbestos Work Across the UK
The ASB5 form requirements apply uniformly across England, Scotland, and Wales under the Control of Asbestos Regulations. However, the enforcing authority varies depending on the type of premises involved.
In London, where construction activity is particularly intensive and the building stock includes a significant proportion of pre-2000 structures, the volume of licensable asbestos work is correspondingly high. Contractors operating in the capital need to be especially diligent about notification timelines and survey requirements. If you need an asbestos survey London based, Supernova operates across the city and surrounding areas.
Regardless of location, the core obligations remain the same. The ASB5 form must be submitted on time, the survey must be in place, and the plan of work must be ready before a single ACM is disturbed.
Keeping Records: What to Retain and for How Long
The Control of Asbestos Regulations set out specific record-keeping requirements for licensed contractors. These are not administrative niceties — they are legal obligations.
Records that must be kept include:
- Copies of all ASB5 form submissions and any correspondence with the enforcing authority
- The written plan of work for each licensable job
- Air monitoring results and analytical reports
- Clearance certificates for each completed job
- Medical surveillance records for workers involved in licensable asbestos work
- Training records for all operatives
Medical surveillance records for asbestos workers must be retained for 40 years — a reflection of the long latency period of asbestos-related diseases. Other records relating to licensable work should be retained for a minimum of five years. Check current HSE guidance for the precise requirements applicable to your circumstances.
Frequently Asked Questions
What is the ASB5 form used for?
The ASB5 form is the official notification document used by licensed asbestos contractors to inform the relevant enforcing authority — either the HSE or the local authority — before carrying out licensable asbestos work. It is a legal requirement under the Control of Asbestos Regulations and must be submitted at least 14 days before work begins.
Who needs to submit the ASB5 form?
Any licensed asbestos contractor planning to carry out licensable asbestos work must submit the ASB5 form. This applies regardless of the size of the job or the duration of the work, provided the work falls within the definition of licensable work under the Control of Asbestos Regulations. The responsibility sits with the licensed contractor, not the client or building owner.
What happens if you submit the ASB5 form late?
Submitting the ASB5 form after the 14-day deadline is itself a breach of the Control of Asbestos Regulations. The enforcing authority can take enforcement action, including issuing improvement notices or prohibition notices. In serious cases, late notification can form part of a wider prosecution. There is no grace period — the deadline is absolute.
Is the ASB5 form the same as an asbestos licence?
No. The ASB5 form is a notification document, not a licence. A contractor must already hold a valid asbestos removal licence issued by the HSE before they can carry out licensable work. The ASB5 form is then used to notify the enforcing authority about a specific piece of licensable work. Both the licence and the notification are required — one does not substitute for the other.
Do I need a survey before completing the ASB5 form?
Yes. The ASB5 form requires accurate information about the type and location of asbestos-containing materials, which can only be confirmed through a professional asbestos survey. A refurbishment survey is typically required before licensable work begins. Without survey data, you cannot complete the form accurately, and submitting incorrect information is itself a regulatory breach. Professional asbestos testing and survey services are available nationwide through Supernova Asbestos Surveys.
