Ceiling tiles are easy to overlook during maintenance and refurbishment, but some older ceiling systems can contain asbestos. In particular, the Health and Safety Executive (HSE) identifies asbestos insulating board (AIB) as a material that was used for ceiling tiles and other fire-protection applications.
If you are planning to drill, lift, replace or remove ceiling tiles in a London property, the key question is not whether the tiles look like asbestos. It is whether reliable asbestos information already exists for the exact area and material that will be disturbed.
Can ceiling tiles contain asbestos?
Yes. HSE guidance lists AIB among asbestos-containing materials that can be found in ceiling tiles, internal partitions, bulkheads, fire doors, lift-shaft linings and soffits. HSE also notes that AIB can resemble ordinary building boards, including plasterboard, so appearance alone is not a reliable way to identify it.
See HSE’s guidance on locations of asbestos and taking the right action.
Asbestos can also be associated with other ceiling materials, including some textured decorative coatings. If the ceiling finish is textured rather than tiled, see our guide to Artex and asbestos.
Why drilling or removing ceiling tiles can matter
Asbestos-containing materials are most likely to create a risk when fibres are released into the air. Cutting, drilling, breaking or otherwise disturbing an asbestos-containing board can increase fibre release. HSE therefore publishes specific Asbestos Essentials task sheets for work involving AIB, including drilling holes and removing a single screwed-in AIB ceiling tile.
These task sheets are guidance for appropriately trained people carrying out work that has already been correctly assessed and classified. They should not be treated as a substitute for first establishing what the material is and whether the proposed work is licensed, notifiable non-licensed or non-licensed.
See HSE Asbestos Essentials and the specific guidance on drilling holes in AIB.
What does the law require before work starts?
Legal requirement: identify asbestos before liable-to-expose work
For employers, Regulation 5 of the Control of Asbestos Regulations 2012 requires a suitable and sufficient assessment before demolition, maintenance or other work that exposes, or is liable to expose, employees to asbestos. If there is doubt about whether asbestos is present, the Regulations require the employer to assume that it is present and apply the relevant controls.
This is different from simply saying that every ceiling in every property must be surveyed. The required action depends on the building, the material, the information already available and the work that is planned.
Legal requirement: duty to manage in relevant premises
Regulation 4 places a duty to manage asbestos in non-domestic premises and relevant common parts of multi-occupancy domestic premises. Where that duty applies, the dutyholder must assess whether asbestos is or is liable to be present, keep relevant information up to date and provide information about its location and condition to people liable to disturb it.
See Regulation 4 of the Control of Asbestos Regulations 2012.
When might existing asbestos information be enough?
You may not need new sampling simply because ceiling tiles are present. Existing information may be sufficient where it is reliable, current enough for the proposed work and clearly covers the exact ceiling area and material to be disturbed.
For example, check whether you already have:
- a previous asbestos survey covering the room and ceiling system;
- sample results that clearly correspond to the same tiles;
- an asbestos register identifying the ceiling material and its condition;
- drawings or survey notes showing inaccessible or excluded areas; and
- information confirming whether later alterations introduced different ceiling tiles.
If the survey recorded an area as inaccessible or excluded, do not assume that it was asbestos-free. Our guide to asbestos survey “no access” areas explains why survey limitations matter before work begins.
When might further inspection or sampling be appropriate?
Further investigation may be appropriate where the existing records do not clearly identify the ceiling material, where the planned work will disturb areas outside the original survey scope, or where the ceiling system has been altered since the earlier survey.
For an isolated suspect material, targeted asbestos sampling may sometimes answer the specific question. Where wider refurbishment will disturb the ceiling, voids, partitions, services or other building fabric, a properly scoped refurbishment asbestos survey may be more appropriate than a single sample.
Ceiling-tile checklist before drilling or removal
| Check | What to confirm |
|---|---|
| Building and alteration history | Whether the ceiling or room may date from a period when asbestos-containing materials were commonly used, and whether later alterations changed the system. |
| Existing asbestos records | Whether a survey, register or laboratory result clearly covers the exact ceiling tiles involved. |
| Survey limitations | Whether the ceiling void, tiles or surrounding areas were recorded as inaccessible, excluded or outside the survey scope. |
| Planned disturbance | Whether the job involves drilling, lifting, cutting, breaking, replacing or removing tiles or accessing the void above. |
| Material condition | Whether tiles are intact, damaged, loose, water-damaged or deteriorated. |
| Work classification | Whether the proposed work is licensed, notifiable non-licensed or non-licensed, based on the material, condition, task and likely exposure. |
| Competence and controls | Whether the people planning and carrying out the work have the appropriate asbestos information, training, risk assessment and controls. |
HSE guidance versus general good practice
HSE’s Asbestos Essentials task sheets describe recognised control methods for specific lower-risk or short-duration tasks. HSE states that following its guidance is not compulsory unless specifically stated, although following it will normally be enough to comply with the law.
As general good practice, property owners and project teams should make sure asbestos information is easy to find, clearly linked to the work area, shared with contractors before work starts and reviewed whenever the project scope changes. This helps prevent a maintenance job from reaching a material that was never properly assessed.
Need to check ceiling tiles before work?
If you are planning ceiling works in a London property and the existing asbestos information is unclear, we can help you define the appropriate survey or sampling scope before contractors disturb the material.
Request a property-specific asbestos survey quote or contact Asbestos London Survey with the property details, the ceiling area involved and the work you intend to carry out.
