What Information Does a Non-Domestic Building’s Asbestos Register Include?
If you manage or own a commercial property in the UK, you’ve almost certainly heard the term “asbestos register” — but what information does a non-domestic building’s “asbestos register” include, exactly? It’s not simply a list of where asbestos was found. A legally compliant register is a detailed, living document that underpins your entire duty to manage asbestos under the Control of Asbestos Regulations.
Get it wrong — or fail to maintain it properly — and you’re exposed to unlimited fines, prosecution, and the very real risk of harm to the people working in and around your building. Asbestos remains the single largest cause of work-related deaths in the UK, and the register is your first line of defence.
The Legal Basis for the Asbestos Register
The Control of Asbestos Regulations place a clear legal duty on anyone responsible for maintaining or managing a non-domestic building to identify, assess, and manage any asbestos-containing materials (ACMs) on site. This duty holder — whether a landlord, facilities manager, or managing agent — must ensure that identified ACMs are recorded in a formal asbestos register.
The Health and Safety Executive (HSE) oversees enforcement and can inspect premises, demand documentation, and prosecute duty holders who fail to comply. The HSE’s guidance document HSG264 provides detailed technical guidance on how surveys should be conducted and how registers should be structured and maintained.
Crucially, these regulations apply to every non-domestic building unless you can demonstrate with certainty that no asbestos is present. That’s a distinction many duty holders miss — the burden of proof sits with you, not with the regulator.
What Information Does a Non-Domestic Building’s Asbestos Register Include?
The asbestos register is the formal record of all ACMs identified during a survey. It must contain enough detail for anyone who might disturb those materials — a maintenance worker, a contractor, or an emergency responder — to understand exactly what they’re dealing with and where.
A fully compliant register will include the following categories of information:
1. The Location of Each ACM
Every asbestos-containing material must be recorded with a precise location — not just “plant room” but a specific description that would allow someone unfamiliar with the building to find it. This is typically supported by annotated floor plans or site maps that form part of the register.
Location descriptions should reference the floor, room number or name, and the specific element of the building fabric where the ACM is found — for example, “ceiling tiles in Room 14, second floor” or “pipe lagging on boiler feed pipe in basement plant room.”
2. The Type of Asbestos
The register must record the type of asbestos fibre identified. The three most commonly encountered types in UK buildings are:
- Chrysotile (white asbestos) — the most widely used historically, found in a broad range of building products
- Amosite (brown asbestos) — frequently found in insulating board, ceiling tiles, and thermal insulation
- Crocidolite (blue asbestos) — the most hazardous fibre type, used in spray coatings and some insulation products
Where the fibre type has been confirmed through laboratory analysis, this should be recorded alongside the sample reference number. Where the type is presumed rather than confirmed, this must also be clearly stated.
3. The Form and Product Type of the ACM
Asbestos appears in many different product forms, and the register should record which type is present. Common examples include:
- Asbestos insulating board (AIB)
- Sprayed coatings
- Pipe and boiler lagging
- Textured decorative coatings (such as Artex)
- Asbestos cement sheets and panels
- Floor tiles and associated adhesives
- Gaskets and rope seals in older plant and equipment
The product type directly affects the risk level — friable materials like sprayed coatings release fibres far more readily than bonded materials like asbestos cement, and this distinction must be captured in the register.
4. The Condition of the Material
The register must record the current condition of each ACM at the time of the survey or most recent re-inspection. HSG264 sets out a structured approach to condition assessment, typically using a scoring system that evaluates:
- The extent of damage or deterioration
- Surface treatment (e.g. whether the material is sealed or painted)
- Whether fibres are visibly exposed
- The likelihood of disturbance given the material’s location and accessibility
A material in poor condition in a high-traffic area presents a very different risk profile to one in good condition in a sealed void — and the register needs to reflect that difference clearly.
5. A Risk Priority Rating
Based on the condition assessment, each ACM should be assigned a risk priority rating. This helps duty holders prioritise action and demonstrates to the HSE that a structured risk management approach is in place.
Risk ratings are typically categorised as high, medium, or low — or expressed numerically — and are derived from the combined assessment of material condition, accessibility, and the likelihood of disturbance during normal building use.
6. The Estimated Quantity or Extent of the Material
The register should record the approximate quantity of each ACM — whether expressed as a surface area (square metres), a linear measurement (for pipe lagging), or a count (for individual tiles or panels). This information is essential for planning remediation work and for calculating disposal requirements if removal becomes necessary.
7. Any Assumptions Made During the Survey
Where a surveyor has been unable to access a particular area, or where sampling was not possible, the register must clearly record this as a presumed or inaccessible area. Presumed ACMs — those treated as containing asbestos in the absence of a negative sample result — must be managed as if they are confirmed ACMs until proven otherwise.
This is a critical point. An asbestos register that shows only confirmed finds and ignores inaccessible or unsampled areas is not compliant and leaves the duty holder exposed.
8. Actions Taken or Recommended
The register should record what action, if any, has been taken in relation to each ACM — for example, whether it has been encapsulated, labelled, or removed. It should also capture any recommended actions arising from the survey or a subsequent re-inspection, along with target completion dates and the name of the responsible person.
9. Survey Date and Surveyor Details
The register must record when the survey was carried out and by whom — including the name of the surveying organisation and their accreditation details. This establishes the provenance of the data and allows the duty holder to demonstrate that the survey was conducted by a competent person.
How the Register Is Produced: The Role of the Survey
The asbestos register cannot be produced without a proper survey. For occupied, non-domestic premises, the starting point is a management survey — a minimally intrusive inspection designed to locate ACMs that could be disturbed during normal occupation and routine maintenance.
Where refurbishment or demolition work is planned, a more intrusive demolition survey is required before work begins. This type of survey accesses concealed voids, lifts floorboards, and breaks into the building fabric to establish a comprehensive picture of all ACMs — including those that wouldn’t be encountered during day-to-day use.
If you’re unsure whether your existing survey is still fit for purpose, or if it was carried out some years ago, it’s worth having it reviewed. Buildings change, and an outdated register can be as problematic as no register at all.
Keeping the Register Up to Date: Re-Inspections
An asbestos register is not a one-time document. Known ACMs must be monitored at regular intervals to check that their condition hasn’t deteriorated. The HSE recommends re-inspection at least every 6 to 12 months, though higher-risk materials may need more frequent assessment.
A re-inspection survey updates the condition scores in the register, flags any deterioration, and revises risk ratings where necessary. The register must be updated following every re-inspection — not simply filed alongside the old version.
The register should also be updated whenever:
- Remediation or encapsulation work is carried out
- An ACM is removed
- Refurbishment work reveals previously unknown ACMs
- A previously inaccessible area is surveyed
- A presumed ACM is either confirmed or cleared by asbestos testing
Who Needs Access to the Asbestos Register?
The register must be made available to anyone who may work on or near ACMs. This is a legal requirement, not a courtesy. In practice, this means:
- In-house maintenance and facilities staff
- External contractors before they begin any work on site
- Emergency services attending an incident
- The HSE if they attend for an inspection
- Any new managing agent or facilities manager taking over responsibility for the building
Failure to share the register with a contractor who then disturbs asbestos can result in prosecution — regardless of whether the contractor knew asbestos was present. The duty holder is responsible for ensuring the information is communicated.
In multi-tenanted buildings, responsibility for sharing the register must be clearly defined in writing between landlord and tenants. Ambiguity is not a defence.
The Asbestos Register and the Management Plan
The register feeds directly into the asbestos management plan — the document that sets out how identified ACMs will be managed over time. While the register records the facts (what’s there, where it is, what condition it’s in), the management plan sets out the actions: who is responsible, what monitoring is in place, how contractors will be briefed, and what happens in an emergency.
Together, the register and the management plan form the core of your asbestos management system. One without the other is incomplete. If your building has a register but no management plan — or a management plan that’s never been implemented — you are not compliant with the Control of Asbestos Regulations.
When Asbestos Removal Affects the Register
When an ACM is removed from a building, the register must be updated to reflect this. The entry should not simply be deleted — it should be marked as removed, with the date of removal, the name of the contractor, and confirmation that the work was carried out in accordance with the relevant requirements.
Most high-risk removal work — including the removal of sprayed coatings, lagging, and asbestos insulating board — must be carried out by a contractor holding a current HSE licence. If you need asbestos removal carried out, always verify that the contractor holds the appropriate licence before work begins.
A properly conducted licensed removal will involve pre-work risk assessment, HSE notification, full enclosure of the work area, continuous air monitoring, and four-stage clearance before the area is reoccupied. The clearance certificate and waste transfer documentation should be retained and referenced in the register.
Practical Steps for Duty Holders
If you’re responsible for a non-domestic building and you’re unsure whether your asbestos register is complete and compliant, here’s where to start:
- Check whether a survey has been carried out. If your building was constructed before 2000 and you have no survey on file, commission one immediately.
- Review the register for completeness. Does it cover the whole building, including plant rooms, roof spaces, and external structures? Are there areas marked as inaccessible or unsampled?
- Check the date of the last re-inspection. If it’s been more than 12 months since ACMs were assessed, a re-inspection is overdue.
- Confirm the register is accessible. Is it held somewhere that contractors and maintenance staff can actually access it before starting work?
- Cross-reference with your management plan. Do the actions in the plan reflect the current condition of ACMs recorded in the register?
- Verify any removals are documented. If ACMs have been removed, is this reflected in the register with supporting documentation?
If you want to confirm whether a suspected material contains asbestos before it’s disturbed, a testing kit allows you to take a sample and have it analysed by an accredited laboratory — a straightforward first step where a full survey isn’t immediately available.
For properties in the capital, our asbestos survey London service covers all boroughs and property types, from commercial offices and retail units to schools and healthcare premises.
It’s also worth noting that if your building requires a fire risk assessment, this can often be combined with an asbestos survey visit to reduce disruption and cost. Both are legal duties for non-domestic premises, and both require regular review.
Frequently Asked Questions
What information does a non-domestic building’s asbestos register include?
A compliant asbestos register includes the location of each ACM (supported by annotated floor plans), the type and form of asbestos, the condition of the material, a risk priority rating, the estimated quantity, any assumptions or inaccessible areas, actions taken or recommended, and the date and details of the survey. It must be kept up to date following re-inspections and any remediation work.
Who is legally required to maintain an asbestos register?
The duty holder — the person or organisation with the greatest degree of control over the non-domestic building — is legally required to maintain the register under the Control of Asbestos Regulations. This is typically the building owner, managing agent, or a tenant holding a full repairing lease. In multi-tenanted buildings, responsibility must be clearly defined in writing.
Does the asbestos register need to be updated regularly?
Yes. The register must be updated following every re-inspection (recommended at least every 6 to 12 months for known ACMs), after any remediation or removal work, and whenever new ACMs are discovered. An outdated register does not fulfil the legal duty to manage asbestos under the Control of Asbestos Regulations.
What happens if a contractor disturbs asbestos that isn’t in the register?
If asbestos is disturbed because it wasn’t recorded in the register, the duty holder may face enforcement action from the HSE — regardless of whether the contractor was aware of the risk. The duty holder is responsible for ensuring the register is complete and that contractors are informed of ACM locations before work begins. Prosecution and unlimited fines are possible outcomes in serious cases.
Can I use a postal testing kit instead of commissioning a full survey?
A testing kit can confirm whether a specific material contains asbestos, but it does not constitute a management survey and cannot produce a compliant asbestos register on its own. A full management survey, carried out by an accredited surveyor, is required to meet your legal duty to manage asbestos in a non-domestic building. Testing kits are useful as a supplementary tool — for example, to confirm the status of a presumed ACM between surveys.
