What Regulation 4 requires
The duty to manage asbestos is set out in Regulation 4 of the Control of Asbestos Regulations 2012. It applies across Great Britain and places an active duty on the person responsible for maintaining or repairing non-domestic premises.
A duty holder must take reasonable steps to establish whether asbestos-containing materials are present. Their location, extent and condition must be recorded. The risk of disturbance must then be assessed and controlled through a written management plan that is implemented, monitored and kept current.
The practical test is simple. Before a contractor drills, cuts, lifts, strips or opens part of the building, can they obtain reliable information about any asbestos they may encounter? If the register is incomplete, inaccessible or no longer matches the premises, the duty is not being managed properly.
The HSE summarises the legal requirements at hse.gov.uk/asbestos/duty.
Who holds the duty
The duty normally follows responsibility for maintenance and repair. Ownership alone does not settle the question. The lease, repairing covenants, management agreement and actual control of the premises all matter.
A freeholder may retain responsibility for the roof, structure, plant rooms and common areas. A tenant may be responsible for the internal fabric of its unit. In a multi-let building, several parties can hold duties at the same time, each within the areas and systems they control.
Typical duty holders include building owners, commercial landlords, tenants with repairing obligations, employers controlling workplace premises and managing agents acting under a maintenance agreement. Where responsibilities overlap, the parties must cooperate and exchange relevant asbestos information.
Establish who controls the risk
We review the premises, available records and management responsibilities to identify the immediate compliance priorities.
Where the duty applies
Regulation 4 covers offices, shops, factories, warehouses, schools, healthcare buildings, hotels, public buildings and other non-domestic premises. It also covers the common parts of multi-occupancy residential buildings, including entrance halls, corridors, stairwells, lift shafts, roof spaces, service risers and communal plant rooms.
The private interior of a domestic home is outside Regulation 4. That does not remove the duties owed to tradespeople working there. Other provisions of CAR 2012 still require employers and contractors to assess asbestos risks before disturbing the building fabric.
Finding asbestos in the building
Buildings constructed or refurbished before 2000 should not be treated as asbestos-free without dependable evidence. Materials I regularly expect to encounter include asbestos insulating board around service risers and fire doors, sprayed coatings on structural steel, lagging to pipework and calorifiers, cement roof sheets, soffits, rainwater goods, textured coatings, floor tiles, bitumen adhesives and asbestos-containing gaskets.
Original drawings and previous surveys are useful, but they rarely settle the position on their own. Buildings change. Partitions move, ceilings are replaced, plant is renewed and inaccessible areas are opened. A register based on an old survey must be checked against the building as it stands today.
A suitable asbestos survey is normally the soundest basis for the register. A management survey supports normal occupation and routine maintenance. Intrusive refurbishment or demolition work requires a survey designed for the full scope of that work. The survey process is covered in how asbestos surveys work.
The asbestos register
The asbestos register should identify known and presumed ACMs by location, material, extent and condition. Photographs and marked plans are valuable where room names are inconsistent or several similar materials occur close together.
A register is not effective merely because it exists. It must be available at the point where work is planned and controlled. Contractors should check it before starting, and the person authorising the work should confirm whether the proposed activity falls within the survey coverage.
Common failures include registers stored away from site, survey limitations copied without action, inaccessible areas forgotten, removed materials left on the register and new survey information never incorporated.
The management plan
The asbestos management plan records how the identified risks will be controlled. It should name the responsible person, set priorities, state how ACMs will be monitored and explain how information will reach employees, contractors and emergency services.
Sound asbestos does not need to be removed simply because it is present. Depending on its condition and the likelihood of disturbance, the correct action may be to leave it in place, label it, protect it, repair minor damage, encapsulate it, restrict access or arrange removal.
The plan must also deal with foreseeable changes. A ceiling void that is safe during normal occupation may become a high-risk work area when new cabling is installed. Planned maintenance, refurbishment and emergency access must therefore be considered before work begins.
Inspection and review
The condition of known and presumed ACMs must be monitored. The management plan should be reviewed at least every 12 months and sooner where work, damage, occupancy changes or new information affects the risk.
The physical inspection interval should reflect the material and its surroundings. A cement roof sheet in a locked store does not present the same likelihood of disturbance as insulating board in a busy service corridor. The findings from asbestos re-inspections should update both the register and the actions in the plan.
What good compliance looks like
A defensible management system is concise and used. The survey coverage is understood. The register matches the current layout. Responsibility sits with a named, competent person. Contractors receive the relevant information before work starts. Damaged materials are acted upon, and scheduled reviews actually take place.
Where one of those controls is missing, closing that gap is more valuable than producing another policy document. The purpose of Regulation 4 is to prevent accidental exposure at the point where the building fabric is disturbed.

Frequently asked questions
Does the duty to manage apply to rented business premises?
Yes, where the tenant has responsibility for maintenance or repair. The lease may divide the duty between the tenant and landlord, particularly in multi-let buildings with shared areas and retained services.
Is an asbestos survey always legally required?
Regulation 4 requires reasonable steps to determine whether ACMs are present and allows materials to be presumed to contain asbestos. In most pre-2000 premises without reliable records, a suitable survey is the practical way to create an accurate register and assessment.
How often should the asbestos management plan be reviewed?
The plan should be reviewed at least every 12 months and sooner after damage, building work, changes in occupation or new asbestos information. The inspection frequency for individual materials should be based on their condition and likelihood of disturbance.
Must asbestos be removed to comply with Regulation 4?
No. ACMs in sound condition can often remain in place under controlled management. Removal becomes appropriate where materials are damaged, vulnerable to disturbance or incompatible with planned work.
