A “no access” entry in an asbestos survey report means that an area was not inspected. It does not confirm that the area is free of asbestos. For London property owners and managing agents, this distinction matters when arranging maintenance or planning building work.
What does “no access” mean?
A survey may record a locked room, inaccessible service riser or another location that could not be inspected. Read the stated reason and identify exactly which space or material the restriction covers. A general statement about a floor or building can hide an important gap in the information available for a particular job.
HSE guidance on arranging asbestos surveys says uninspected areas must be presumed to contain asbestos and managed accordingly until inspected. Restrictions can significantly reduce a survey’s usefulness.
Check the report against the work you are planning
Start with the survey scope, plans and limitations, rather than reading only its summary. HSE advises checking for unagreed caveats, clear plans and whether all rooms and areas were accessed. A management survey supports normal occupation; refurbishment or demolition work requires information about hidden materials affected by that work.
For example, imagine a communal corridor survey that excludes a locked service cupboard. If a contractor later needs to run cables through that cupboard, the corridor findings alone do not answer the asbestos question for the cable route. This is an illustrative example, not a report of a particular property.
Five questions to send to your surveyor
- Which exact locations were inaccessible, and are they marked on the plan?
- Why was access unavailable, and what arrangements are needed for another visit?
- Does our proposed work enter any excluded space or disturb materials outside the original scope?
- What further investigation is appropriate before that work starts?
- How will the additional findings be linked to the existing report and register?
Send the existing report alongside a written description of the work. Include the rooms involved, proposed routes through walls or ceilings, and available drawings. This gives the surveyor a clearer basis for defining the next inspection.
Record the gap and tell contractors
Where an asbestos register is maintained, inaccessible locations should remain clearly identified as presumed asbestos areas. HSE’s register guidance includes both known and presumed asbestos, its location and condition, and the potential for disturbance.
HSE also states that uninspected areas need surveying before work takes place there. Share these limitations with maintenance teams and external contractors; a report filed away without explaining its exclusions is insufficient for planning the job. See HSE’s guidance on putting the management plan into action.
Does a limitation mean the whole survey is useless?
Not necessarily. Findings from inspected areas may still be useful, but the missing information must be considered in relation to the intended use of the report. Ask the surveyor to explain what can be relied on and what still needs investigation. Do not treat an exclusion as permission to proceed.
