What the Control of Asbestos Regulations 2012 Actually Requires — And What Most Dutyholders Get Wrong
Asbestos kills around 5,000 people in the UK every year. That figure has remained stubbornly high because, despite decades of regulation, many businesses and property managers still misunderstand what the law demands of them. The Control of Asbestos Regulations 2012 is the cornerstone of UK asbestos law, yet it is routinely misapplied, partially followed, or simply ignored.
Whether you manage a single commercial property or a large estate portfolio, understanding exactly what the regulations require — and where the common pitfalls lie — could be the difference between a safe building and a criminal prosecution.
The Legal Foundation: What the Control of Asbestos Regulations 2012 Establishes
The Control of Asbestos Regulations 2012 consolidated and replaced earlier legislation, creating a single, unified framework for managing asbestos across the UK. It applies to all non-domestic premises and, in certain circumstances, to the common parts of domestic buildings such as blocks of flats.
The regulations are underpinned by HSE guidance — most notably HSG264 — which sets out the practical methodology for asbestos surveys. Together, these documents define how dutyholders must identify, assess, manage, and control asbestos-containing materials (ACMs).
The regulations do not simply prohibit asbestos work. They create a structured system of duties, licences, notifications, training requirements, and health surveillance obligations. Understanding the full scope of that system is essential for anyone responsible for a building constructed before the year 2000.
The Duty to Manage: Regulation 4 Explained
Regulation 4 is arguably the most significant provision in the entire framework. It places a legal duty on anyone who has responsibility for the maintenance or repair of non-domestic premises to actively manage asbestos within those premises. This is not a passive obligation — it requires deliberate, documented action.
What Regulation 4 Requires in Practice
- Identify whether ACMs are present, or are likely to be present, in the premises
- Assess the condition of any ACMs found and the risk they present
- Prepare and implement a written asbestos management plan
- Review and monitor that plan on a regular basis
- Provide information about ACMs to anyone liable to work on or disturb them
The starting point for almost all of this is a professional asbestos survey. Without one, you cannot accurately identify what is present, and without that information, your management plan is built on guesswork.
A management survey is the standard survey type for buildings in normal use. It is designed to locate ACMs that could be damaged or disturbed during everyday occupation, including routine maintenance activities, and it forms the foundation of any compliant management plan.
Licensed, Non-Licensed, and Notifiable Non-Licensed Work
One of the areas where dutyholders most frequently come unstuck is understanding which category of work applies to their situation. The Control of Asbestos Regulations 2012 divides asbestos work into three distinct categories, each carrying different legal requirements.
Licensed Work
The most hazardous asbestos work must be carried out by a contractor holding a licence issued by the HSE. This includes work on sprayed coatings, asbestos insulation, and asbestos insulating board (AIB) where the work is not of short duration. Licensed contractors must notify the HSE before work begins, maintain health records for workers, and ensure those workers are under medical surveillance.
Non-Licensed Work
Some lower-risk asbestos work can be carried out without a licence. This typically involves materials in good condition where fibre release is minimal. However, the work must still be carried out safely, with appropriate controls in place. The absence of a licence requirement does not mean the absence of legal obligations.
Notifiable Non-Licensed Work (NNLW)
NNLW sits between the two categories. It does not require a licence, but it does require the employer to notify the relevant enforcing authority — usually the HSE — at least 14 days before work commences. NNLW also triggers additional obligations:
- Workers must be under medical surveillance by an HSE-appointed doctor
- Health records must be maintained for a minimum of 40 years
- Records of the work itself must be kept
Failing to notify before NNLW commences is a criminal offence. It is also one of the most commonly missed requirements, particularly among smaller contractors who are not fully familiar with the regulations.
Asbestos Surveys: Commissioning the Right Type
Before any of the management obligations under the Control of Asbestos Regulations 2012 can be fulfilled, you need reliable information about what is in your building. That means commissioning the right type of survey for your circumstances — and getting this wrong is more common than many dutyholders realise.
Management Surveys
A management survey is required for the ongoing management of ACMs in a building in normal use. HSG264 sets out the methodology surveyors must follow, including the sampling and assessment procedures that underpin a reliable asbestos register.

Refurbishment and Demolition Surveys
If you are planning any refurbishment or demolition work, a management survey is not sufficient. You need a demolition survey, which is far more intrusive and is designed to locate all ACMs in the areas to be affected before any work begins. Commissioning the wrong survey type can leave ACMs undiscovered, putting workers at risk and exposing dutyholders to significant legal liability.

Training Requirements Under the Regulations
The Control of Asbestos Regulations 2012 places explicit training obligations on employers. The level of training required depends on the nature of the work being carried out — and employers cannot simply point workers at an online video and consider the obligation discharged.
Asbestos Awareness Training
Anyone whose work could foreseeably disturb asbestos — even accidentally — must receive asbestos awareness training. This covers a wide range of trades: electricians, plumbers, joiners, painters, and general maintenance operatives are all included. The training must cover what asbestos is, where it is likely to be found, how to recognise it, and what to do if it is encountered.
Training for Non-Licensed and NNLW
Workers carrying out non-licensed or notifiable non-licensed work need more detailed training. This goes beyond awareness and covers the specific procedures, controls, and protective equipment required for the work in question. Training must be appropriate to the role, regularly refreshed, and properly documented. The HSE can and does ask for evidence of training during inspections.
Medical Surveillance: An Obligation That Is Frequently Overlooked
Medical surveillance is one of the less visible requirements of the Control of Asbestos Regulations 2012, but it is legally binding for workers engaged in licensed work and NNLW. Workers must be examined by an HSE-appointed doctor before they begin working with asbestos and at regular intervals thereafter — at least every three years.
The purpose is to identify any early signs of asbestos-related disease so that appropriate action can be taken. Employers must maintain health records for 40 years from the date of the last entry. This is not a recommendation — it is a legal requirement. The long latency period of asbestos-related diseases means those records may be needed decades after exposure occurred.
Asbestos Removal: When Management Is No Longer Enough
Not all ACMs need to be removed. In many cases, materials in good condition that are not likely to be disturbed are best left in place and managed. Disturbance during removal can actually increase fibre release and risk. However, there are circumstances where removal becomes necessary:
- The material is in poor condition and deteriorating
- Refurbishment or demolition work will disturb the material
- The material cannot be adequately protected or encapsulated
- The building is being sold or repurposed
When removal is required, it must be carried out in compliance with the Control of Asbestos Regulations 2012. For licensed materials, only an HSE-licensed contractor may undertake the work. Our asbestos removal service is carried out by fully licensed operatives working to all relevant regulatory requirements.
Following removal, a four-stage clearance procedure is required before the area can be reoccupied. This includes a thorough visual inspection and air testing carried out by an independent analyst. Skipping or abbreviating this process is not only dangerous — it is a breach of the regulations.
Enforcement, Penalties, and the HSE’s Approach
The HSE takes asbestos enforcement seriously. Inspectors have the power to issue improvement notices, prohibition notices, and to prosecute dutyholders who fail to comply with the Control of Asbestos Regulations 2012. Prosecutions can result in substantial fines and, in serious cases, custodial sentences.
Courts have consistently taken a dim view of dutyholders who were aware of their obligations but failed to act on them. The defence of ignorance carries very little weight when the regulations are clear and widely publicised.
Beyond criminal liability, dutyholders who fail to manage asbestos properly expose themselves to civil claims from workers or occupants who develop asbestos-related disease as a result of that failure. The consequences can be financially devastating and reputationally catastrophic.
The Regulatory Landscape: Where Things Are Heading
The framework around asbestos is not static. The HSE and government have been actively reviewing aspects of the current system, with focus on several key areas.
Strengthening NNLW Documentation
There is ongoing discussion about requiring more detailed documentation for NNLW, including clearer records of the work carried out, the controls used, and the workers involved. This would improve oversight and make it easier to trace exposure histories in the event of future health claims.
Expanding Medical Surveillance Coverage
Proposals under consideration would extend medical surveillance requirements to cover a broader range of workers, reflecting a growing understanding of cumulative low-level exposure risks. The emphasis is on early detection and long-term monitoring.
Legacy Asbestos in the Built Environment
A significant volume of asbestos remains in UK buildings, particularly in schools, hospitals, and commercial premises built between the 1950s and 1980s. Government and industry bodies are continuing to research the best approaches to managing this legacy stock, balancing the risks of disturbance during removal against the long-term risks of leaving materials in place.
For businesses in the North West, our asbestos survey Manchester service covers the full range of property types, including older commercial stock where legacy asbestos is most commonly encountered.
Practical Steps for Dutyholders Right Now
If you are responsible for a non-domestic property built before 2000 — or the common parts of a residential building — here is what you should be doing to ensure compliance with the Control of Asbestos Regulations 2012.
- Commission a management survey if you do not already have one. This is the foundation of everything else. Without it, you cannot fulfil your duty to manage.
- Review your asbestos register if one exists. Is it current? Has the condition of materials changed? Has any work been done that could have disturbed ACMs?
- Update your asbestos management plan to reflect current conditions and any changes in building use or occupancy. A plan that was written five years ago and never reviewed is not compliant.
- Inform all relevant workers and contractors of the location and condition of ACMs before they begin any work. This is a specific legal requirement under Regulation 4, not a courtesy.
- Check training records for all employees and contractors who could disturb asbestos. If records are missing or out of date, address this before the next inspection or job.
- Verify contractor credentials before commissioning any asbestos work. For licensed work, check the contractor holds a current HSE licence. Do not take this on trust.
- Ensure medical surveillance obligations are met if you employ workers carrying out licensed or notifiable non-licensed work. Health records must be in place and properly maintained.
None of these steps are optional. Each one corresponds to a specific legal obligation under the Control of Asbestos Regulations 2012. Treating them as a checklist rather than a bureaucratic exercise is the right mindset — and it is the approach the HSE expects to see.
Frequently Asked Questions
Who does the Control of Asbestos Regulations 2012 apply to?
The regulations apply to anyone who has responsibility for the maintenance or repair of non-domestic premises. This includes employers, building owners, managing agents, and facilities managers. In some circumstances — such as blocks of flats — the regulations also apply to the common parts of domestic buildings. If you have any contractual or legal responsibility for a building’s upkeep, the duty to manage asbestos almost certainly applies to you.
Do the regulations apply to buildings where asbestos has not been found?
Yes. The duty to manage applies regardless of whether asbestos has been confirmed. If you have not had a survey carried out, you must presume that ACMs are present in any building constructed before 2000 and manage accordingly. The absence of a survey is not a defence — it is itself a failure to meet the obligations under Regulation 4.
What is the difference between licensed and notifiable non-licensed work?
Licensed work covers the most hazardous asbestos activities — such as work on asbestos insulation, sprayed coatings, or asbestos insulating board — and must be carried out by an HSE-licensed contractor. Notifiable non-licensed work (NNLW) covers lower-risk activities that do not require a licence but must still be notified to the HSE at least 14 days before work begins. NNLW also triggers medical surveillance and record-keeping obligations. The distinction matters because getting it wrong — in either direction — creates legal exposure.
How often does an asbestos management plan need to be reviewed?
The regulations require the management plan to be reviewed and kept up to date. In practice, this means reviewing it at least annually and whenever there is a change in circumstances — such as a change in building use, completion of refurbishment work, or a change in the condition of known ACMs. A plan that is never reviewed is not compliant, even if it was thorough when first produced.
What happens if a dutyholder fails to comply with the Control of Asbestos Regulations 2012?
Non-compliance can result in HSE enforcement action, including improvement notices, prohibition notices, and criminal prosecution. Fines can be substantial, and in serious cases courts have imposed custodial sentences. Beyond criminal penalties, dutyholders may also face civil claims from individuals who develop asbestos-related disease as a result of exposure caused by a failure to manage. The reputational and financial consequences of non-compliance can be severe and long-lasting.
