What is asbestos?
Asbestos is a group of naturally occurring fibrous minerals that were widely used in construction until the late 1990s.
Builders valued it for its strength, heat resistance, and insulating properties, but its use as construction material was banned from the UK in 1999.
This applied to all types: Chrysotile (white), amosite (brown), and crocidolite (blue). Despite the ban, asbestos remains present in many buildings constructed before 2000.
Intact asbestos becomes dangerous when disturbed. Intact materials pose minimal risk, but damaged or deteriorating asbestos releases microscopic fibres into the air. These fibres cause serious respiratory diseases when inhaled, including mesothelioma and asbestosis.
For businesses, this creates an ongoing duty of care. Commercial premises built or refurbished before 2000 may still contain asbestos. Owners and employers must manage this risk under UK law.
What does asbestos look like?
Asbestos is difficult to identify visually because it rarely appears in its native, fibrous form. In practice, it is bound within other products, and appears as follows:
- Pipe lagging: A soft, grey or white wrapping around pipes and boilers. It often has a fibrous, rope-like texture and may appear frayed or crumbling with age. This form is commonly found in older plant rooms and basements.
- Textured coatings: Artex-style ceiling and wall finishes with a stippled or swirled pattern. It looks identical to standard decorative plaster, which makes it especially hard to identify without testing.
- Cement products: Grey, rigid sheeting, tiles, or corrugated panels. It has a smooth, dense surface and is often used for roofing, wall cladding, and outbuildings. This form is generally low-risk unless cut, drilled, or damaged.
- Insulation boards: Plain white or grey panels with a flat, slightly chalky surface. Typically found lining ceilings, partitions, and fire doors. These boards release fibres more readily than cement products if disturbed.
Identifying the specific mineral by colour alone is unreliable, as paint, dust, and ageing often mask the natural tones of chrysotile (white/grey), amosite (brown), and crocidolite (blue).
Only laboratory analysis can confirm whether a material contains asbestos. Businesses should treat any suspect material in a pre-2000 building with caution until tested.
Duty of care when handling asbestos
Asbestos is classed as a hazardous material, and as such, a legal duty of care applies to anyone who owns, manages, or works in a building that contains it.
This duty falls under the Control of Asbestos Regulations 2012, and applies to employers, building owners, and those responsible for premises maintenance. It is often referred to as the “duty to manage” asbestos.
The duty requires several actions:
- Identify the location and condition of asbestos-containing materials.
- Assess the risk of exposure.
- Record findings in an asbestos register.
- Create a management plan to monitor or remove the material safely.
- Share this information with anyone who may disturb the material, such as contractors or maintenance staff.
Failure to meet this duty carries serious consequences. The Health and Safety Executive (HSE) can issue improvement notices, prohibition notices, or prosecute non-compliant businesses, with penalties including unlimited fines and, in severe cases, imprisonment.
This duty of care underpins every stage of asbestos management, from initial identification through to final disposal.
Disposal methods of asbestos
Asbestos disposal is tightly regulated. It cannot be placed in general waste or standard skips, and businesses must follow a strict process from removal to final disposal:
1. Safe removal
Removal of materials containing asbestos is considered high-risk work, which legally requires a licensed contractor.
This applies to materials such as sprayed coatings, lagging, and insulation boards, where fibres are more easily disturbed.
Lower-risk materials, like cement sheeting, may be removed by trained non-licensed workers in some cases, provided the work follows HSE guidance.
2. Containment
Removed asbestos must be double-bagged or wrapped in heavy-duty polythene, and clearly labelled as hazardous. This prevents fibre release during transport and handling.
3. Asbestos transport
Asbestos waste is classed as hazardous waste, and must be transported by a licensed waste carrier holding the appropriate environmental permit.
A consignment note (as opposed to a waste transfer note, used for non-hazardous waste) must accompany every load, recording its origin, contents, and destination.
This creates a traceable paper trail from the point of removal to final disposal, and is a legal requirement under UK commercial waste regulations.
4. Asbestos disposal
Asbestos waste cannot go to standard landfill sites, but can only go to licensed hazardous waste sites, which are specifically permitted to accept this material.
These sites bury it in designated, sealed cells, which isolate the material from the environment permanently and prevent any future fibre release.
5. Necessary documentation
Businesses must keep consignment notes for at least three years. This provides evidence of compliant disposal, and also protects against future liability, should any dispute or investigation arise regarding the asbestos’s handling or whereabouts.
What happens to asbestos waste at landfill?
Here is what happens once asbestos waste arrives at the specialised landfill site:
- Waste acceptance checks: Operators check the load against its consignment note to confirm its origin and contents.
- Controlled placement: Operators place the waste directly into a designated cell, keeping it separate from general waste streams.
- Covering the asbestos waste: Operators bury the material within the cell and cover it promptly with soil or another inert material, limiting disturbance and preventing fibres from becoming airborne. They also keep detailed records of the exact burial location, creating a permanent map of where the asbestos sits within the site.
- Long-term containment: Once a cell reaches capacity, operators cap and seal it permanently. This isolates the asbestos from the surrounding environment, and the location remains recorded indefinitely, even after the landfill closes. This is necessary because asbestos does not degrade and remains indefinitely hazardous.
Legal requirements for asbestos disposal
Aside from the general duty of care, specific regulation governs how asbestos waste must be handled, transported, and disposed of. This regulation is largely consistent UK-wide, with only the naming and regulatory bodies differing by nation.
Asbestos disposal regulations in the UK
The following rules apply consistently across all regions, regardless of local classification differences:
- Asbestos classification threshold: Waste is classed as hazardous when it exceeds 0.1% asbestos content.
- Handling and packaging: Asbestos waste must be double-bagged or securely wrapped, and clearly labelled, before it can be moved or stored, per Schedule 2 of the Control of Asbestos Regulations 2012 (CAR 2012).
- Transport classification: Loose or friable asbestos, the most hazardous type, must be transported as a classified dangerous good under CDG 2009, with UN-certified packaging.
- Authorised disposal only: Asbestos waste can only be accepted at UK landfill sites authorised to accept hazardous waste, either through a Waste Management Licence (WML) or a PPC permit.
Asbestos disposal regulation differences in England, Wales, and Scotland
The underlying requirements are near-identical across all three nations. The differences come down to naming and which regulator oversees them:
| England | Wales | Scotland | |
|---|---|---|---|
| Waste classification | Hazardous waste (Hazardous Waste Regulations 2005) | Hazardous waste (Hazardous Waste Regulations 2005) | Special waste (Special Waste Regulations 1996, amended 2004) |
| Documentation | Hazardous Waste Consignment Note | Hazardous Waste Consignment Note | Special waste consignment note (SEPA) |
| Carrier registration | Environment Agency (EA) | Natural Resources Wales (NRW) | Scottish Environment Protection Agency (SEPA) |
Safety precautions and training for asbestos management
The Control of Asbestos Regulations 2012 split asbestos work into three categories, each with its own training, licensing, and monitoring requirements.
Staff who don’t carry out any of this work, such as office and facilities teams, still need basic awareness training on identifying and avoiding asbestos materials.
The three work categories are summarised in the table below.
| In-house work | Notifiable non-licensed work (NNLW) | Licensed contractor work | |
|---|---|---|---|
| What it means | Lower-risk work a business can legally carry out itself, without a licensed contractor | A middle tier that doesn't require a licence, but must be notified to the enforcing authority before work begins | Higher-risk work that can only legally be carried out by an HSE-licensed contractor |
| Who it involves | Trained maintenance staff | Trained non-licensed workers | Licensed contractors and their employees |
| Asbestos risk level | Low. Bonded materials in good condition, e.g. cement sheeting, textured coatings | Medium. e.g. insulation board in good condition, larger-scale cement sheet removal | High. e.g. sprayed coatings, lagging, most insulation board |
| Asbestos licence required | No | No | Yes, an asbestos licence from the Health and Safety Executive (HSE) |
| HSE Notification | Not required | Must notify the relevant enforcing authority before work begins | Must notify the relevant enforcing authority before work begins |
| Worker register | Not required | Employer must keep a record of all workers involved and their exposure levels | Employer must keep a record of all workers involved and their exposure levels |
| Medical surveillance | Not required | Required before work starts, renewed every 3 years | Required before work starts, renewed every 3 years |
| Training required | Task-specific training for the work involved | Task-specific training for the work involved | Full licence-level training, with ongoing HSE vetting |
| PPE/RPE | Disposable protective clothing and suitable RPE | Disposable protective clothing and suitable RPE | Disposable protective clothing and RPE, individually face-fit tested |
| Working methods | Wetting materials to suppress dust | Wetting, sometimes combined with enclosures | Full enclosures, negative-pressure units, and wetting |
| Air monitoring/clearance test | Not typically required | Sometimes required | Typically required, ending in a four-stage clearance test |
| Enforcement | Non-compliance at any level risks HSE enforcement action. | Non-compliance at any level risks HSE enforcement action. | Non-compliance at any level risks HSE enforcement action. |
Is asbestos classified as hazardous waste?
Yes, asbestos waste is classed as hazardous waste in England and Wales, and as special waste in Scotland, whenever it exceeds 0.1% asbestos content.
This threshold is set out in the Hazardous Waste Regulations 2005 (England and Wales) and the Special Waste Regulations 1996 (Scotland).
Once classified, it must be handled, transported, and disposed of according to the requirements covered in the sections above.
Can asbestos waste be recycled?
No. Asbestos cannot be processed like paper, plastic, or metal, and standard recycling facilities cannot accept it.
However, while it is a difficult material to recycle, an emerging thermal treatment process does exist, which heats asbestos to extreme temperatures, converting the hazardous fibres into inert glass or ceramic material.
This can strip the material of its hazardous classification entirely, allowing it to be reused in products such as construction aggregate.
This process remains experimental in the UK, limited to a handful of specialist sites, and not yet cost-competitive with landfill.
For most businesses, licensed landfill disposal remains the only practical route. Get quotes for handling commercial asbestos waste through our commercial waste collection services.
Can asbestos waste be incinerated?
No, asbestos waste cannot be incinerated because asbestos fibres are heat-resistant and survive combustion, so incineration doesn’t destroy it, but risks releasing airborne fibres instead.
