What Is an Asbestos Survey?
An asbestos survey is a planned inspection of a defined building or work scope to obtain asbestos information for a specific purpose. It should be carried out by a competent survey provider, with the scope, access, sampling and limitations agreed in advance. HSE strongly recommends accredited or certificated surveyors, but provider evidence must be checked for the actual instruction.
The Control of Asbestos Regulations 2012 (CAR 2012) places the duty to manage on the person or organisation responsible for maintenance or repair of relevant non-domestic premises. A survey is a common route where existing asbestos information is inadequate, but the legal duty is to obtain and manage adequate information rather than to commission one identical survey in every premises. For domestic work, use the survey or sampling scope needed for the areas that planned work may disturb.
Key rule: Before refurbishment or demolition work that may disturb asbestos-containing building fabric, the employer or dutyholder must have adequate asbestos information for the work. Where existing information is not sufficient, use the appropriate intrusive survey route before work begins.
The Three Types of Asbestos Survey
The HSE's guidance document HSG264: Asbestos: The Survey Guide defines three types of survey, each suited to a different purpose. Choosing the wrong survey type is a common and costly mistake.
Management SurveyFor asbestos management during normal occupationWhen is it needed?Used where a dutyholder needs adequate asbestos information for normal occupation and maintenance. It is not an automatic requirement for every domestic property.What does it involve?The competent survey provider inspects the areas included in the agreed scope and records materials that may be disturbed during normal occupation or foreseeable maintenance. Sampling is used where required and authorised.What does the report contain?A report and asbestos information for the agreed management scope, including findings, assumptions, limitations and material-condition information where applicable.Typical costPrice depends on the premises, access, scope, sampling requirement and provider; obtain an itemised quotation.Not suitable for: Intrusive refurbishment or demolition where hidden building fabric will be disturbed; a more intrusive survey route may be needed.Refurbishment SurveyBefore intrusive refurbishment in the affected areaWhen is it needed?Used before refurbishment or installation work where building fabric will be disturbed and the existing asbestos information is not adequate for that work.What does it involve?A more intrusive survey of the parts of the building that the planned works will disturb. Access and destructive inspection are agreed around the actual work area and scope.What does the report contain?A report identifying or presuming ACMs within the agreed refurbishment scope so the work can be planned using the correct asbestos work category and controls.Typical costPrice depends on the refurbishment scope, access, destructive inspection and sampling requirement; obtain an itemised quotation.Not suitable for: Areas outside the planned refurbishment scope unless they are included in the instruction.Demolition SurveyBefore demolition in the structure or area to be demolishedWhen is it needed?Used before demolition where the building or part of it will be substantially disturbed and adequate asbestos information is needed for that work.What does it involve?An intrusive survey designed to locate ACMs within the demolition scope, including areas that are not normally accessible during occupation.What does the report contain?A report for the demolition scope. Any identified work must then be classified correctly: suitable non-licensed/NNLW work and licensable work use different contractor routes.Typical costPrice depends on building size, complexity, access, destructive inspection and sampling requirement; obtain an itemised quotation.Not suitable for: Normal occupied-building management where a less intrusive management-survey scope is sufficient.

What Happens During an Asbestos Survey?
Many property owners are uncertain about what a survey actually involves. Here is the full process from initial enquiry to receiving your report.
1
Initial Enquiry & Scoping
Agree the purpose of the survey, premises or work area, existing asbestos information, access limits and who the competent survey provider will be. The provider should be suitable for the actual scope rather than chosen by a generic badge claim.
2
Site Inspection
The competent survey provider inspects the areas included in the agreed scope and records suspect or presumed materials, access limitations and any areas not inspected.
3
Sampling Where Required
Where material confirmation is needed and sampling is within scope, representative samples are taken by a competent person using suitable controls. This guide does not provide a DIY sampling procedure.
4
Laboratory Analysis
Where samples are taken, the laboratory/provider and relevant accredited scope are confirmed for the instruction. Reporting time depends on the provider and is not fixed by this guide.
5
Report Production
The report should state the survey type and scope, findings, sampled or presumed materials, exclusions, limitations and the information needed for the management or planned-work decision.
6
Next Steps
Use the report to manage materials or plan work. The material, condition and task determine whether any work is non-licensed, NNLW or licensable; licensable work requires an HSE-licensed contractor.
How to Read an Asbestos Survey Report
A well-produced asbestos survey report can be a dense document. Understanding its key sections will help you act on the findings correctly.
Scope & LimitationsThe survey type, areas included, access restrictions, exclusions, assumptions and any areas not inspected.Asbestos Register / FindingsA record of identified, presumed or sampled ACMs within the agreed scope, with location and material information appropriate to the report.Material AssessmentCondition and material-assessment information where appropriate to the survey type. A separate priority assessment or management decision depends on use and likelihood of disturbance.PhotographsPhotographs may be included where they help identify locations or material condition; exact report content depends on the agreed provider scope.Plans or Location ReferencesA floor plan, sketch or other location reference may be used to help the dutyholder or project team find recorded items.Laboratory Results Where Samples Were TakenWhere sampling is part of the instruction, the report should link the relevant laboratory results to the sampled materials. Provider and accredited scope are job-specific.
Key rule: Any ACM with a risk score of 4 or above on the standard HSE matrix requires a management plan or immediate remedial action. Do not ignore high-scoring items: they represent a legal obligation as well as a health risk.
How to Choose an Asbestos Surveyor
Survey quality depends on competent planning, inspection, sampling where required and accurate reporting. HSE strongly recommends using accredited or certificated surveyors. Check the provider evidence and accreditation or certification that applies to the actual survey scope rather than relying on a generic sitewide claim.
BOHS P402 can form part of an individual surveyor’s evidence of knowledge, but it is not a universal statutory licence. Confirm that the actual surveyor or organisation is competent for the agreed survey type, scope and premises.
Compare the proposed survey scope, exclusions, access, provider competence, sampling plan, laboratory arrangements and report deliverables rather than choosing on price alone. For a wider contractor-selection checklist, see: How to Choose an Asbestos Contractor.
Check impartiality and conflicts: HSE surveying guidance expects competence, integrity and impartiality. Review the actual provider relationship and any conflict relevant to the instruction rather than applying a blanket rule that a survey and removal business can never be related.
What Happens After the Survey?
The action you take after receiving your survey report depends on the survey type and the findings. For a management survey, ACMs in good condition can remain in place: but you must create and maintain an asbestos register and management plan, and ensure that anyone who might disturb the ACMs (maintenance contractors, tradespeople) is informed of their location.
After a refurbishment or demolition survey, the planned work must account for the ACMs identified in the affected scope. The material, condition and task determine whether any removal is non-licensed, NNLW or licensable. Licensable work requires an HSE-licensed contractor, and four-stage clearance applies only where the licensed-work handback route requires it. See: Asbestos Air Clearance Certificates Explained.
If a survey identifies work within Pro Asbestos Removal’s confirmed non-licensed/NNLW scope, request a written quotation for that direct work. Licensable work requires an HSE-licensed contractor. Survey, laboratory and analyst credentials are confirmed for the provider actually involved in the individual instruction. Call us on 07345 062075 or request a free quote online.

Common Questions
Do I need an asbestos survey before selling my house?
There is no universal legal requirement to commission an asbestos survey before every domestic sale. A buyer, valuer or solicitor may request more information depending on the property, existing records and planned works. Where a survey is commissioned, its scope and limitations should be clear.
How long does an asbestos survey take?
Survey and report timing depends on the premises, access, survey type, sampling requirement and provider arrangements. The competent provider should confirm the site duration and report timetable for the individual instruction; there is no single 24-hour, 48-hour or working-day turnaround that applies to every survey.
Who can carry out an asbestos survey?
An asbestos survey must be carried out by someone competent for the survey type and scope. HSE strongly recommends accredited or certificated surveyors. Check the actual provider's competence and the accreditation or certification relevant to that instruction rather than relying on a qualification name alone.
What is the difference between a survey and an asbestos test?
Sampling answers a material-identification question about the specific sample submitted to a laboratory. A survey examines a defined building or work scope and records asbestos information for that purpose. Neither route proves what is present outside its agreed scope or in inaccessible areas.
Can I carry out my own asbestos survey?
Do not use this guide as a DIY survey or sampling procedure. Formal asbestos surveying requires competence, a defined scope and suitable controls. If you need asbestos information for management or planned intrusive work, use a competent survey provider or material-testing route appropriate to the task.
How much does an asbestos survey cost?
Cost depends on the premises, survey type, scope, access, destructive inspection, sampling requirement, laboratory charges and provider. Request an itemised quotation for the actual instruction rather than relying on a generic price range from this guide.
