Asbestos Surveys: What Building Managers Need to Know Before Commissioning One

Commissioning an asbestos survey is one of the first steps in meeting your duty to manage asbestos. But the quality of that survey -- and the decisions you make before, during, and after the process -- will determine whether you end up with a genuinely useful management tool or a document full of gaps and assumptions.

This guide covers the practical considerations that building managers, facilities teams, and duty holders should address when appointing an asbestos surveyor and commissioning survey work.

The Two Types of Asbestos Survey

The current survey guidance (HSG264) defines two types of asbestos survey:

Management Survey

The management survey is the standard survey type used to comply with the duty to manage asbestos in non-domestic premises. Its purpose is to locate asbestos-containing materials (ACMs) that could be disturbed during normal occupancy, routine maintenance, and minor repair work.

A management survey:

- Is intrusive to a degree -- the surveyor should access ceiling voids, look under carpets, inspect behind service hatches, and examine lift shafts, riser ducts, and under-floor service ducts
- Involves sampling -- suspect materials are sampled and sent to a laboratory for analysis
- May include presumptions -- where sampling is not possible or practical, the surveyor may presume a material contains asbestos
- Produces a report with material assessments, risk scores, and recommendations

A common misconception is that management surveys are "non-intrusive" or "visual only." They are not. The guidance is clear that surveyors should access concealed spaces where reasonably practicable. A management survey that avoids lifting ceiling tiles or pulling up carpet edges is not meeting the standard.

Refurbishment and Demolition (R&D) Survey

The R&D survey is required before any refurbishment or demolition work that will disturb the building fabric. It is:

- Fully intrusive -- the surveyor will break into walls, floors, ceilings, and other building elements to identify hidden ACMs
- Specific to the work area -- the survey scope is defined by the planned works
- Destructive by nature -- expect disturbance to finishes and fabric
- Should have no exclusions -- the aim is to identify all asbestos within the work zone (though surveyor safety and structural integrity may require phased access)

In some cases, the R&D survey is split into two phases: an initial phase covering areas that can be safely accessed, followed by a second phase once demolition or strip-out has progressed enough to expose remaining concealed areas.

Which Survey Do You Need?

- For ongoing management and compliance: Management survey
- Before any planned refurbishment, renovation, or demolition: R&D survey
- For minor works where the management survey was thorough: The existing management survey data may be sufficient, provided the duty holder is satisfied that the information covers the work area. If there is any doubt, commission an R&D survey for the specific area.

Most clients carrying out refurbishment work will opt for an R&D survey. The management survey, by its nature, may not have investigated deep enough into the building fabric to give confidence about what lies behind fixed walls and within structural elements.

Choosing a Competent Surveyor

Assess the Individual, Not Just the Company

Many surveying companies will send a sales representative or project manager to price the work, but a different person will carry out the actual survey. Make sure you assess the competency of the individual surveyor who will be on site, not just the company's credentials.

Ask:

- What qualifications and training does the surveyor hold?
- How many years of survey experience do they have?
- Can they demonstrate knowledge of the types of ACMs likely to be found in your building's construction era?

Accreditation

The Health and Safety Executive strongly recommends using UKAS-accredited surveyors. However, accreditation is not a legal requirement. What matters is that the survey is carried out in accordance with HSG264. If a surveyor follows the guidance correctly, the data should be reliable regardless of accreditation status.

That said, accreditation provides an additional layer of quality assurance. Accredited laboratories are audited regularly, and their processes are independently verified. For large or complex buildings, or where the survey data will be relied upon for significant management decisions, accredited surveyors provide additional confidence.

The Key Question to Ask

Above all, ask this: "Will the survey be carried out in full accordance with HSG264?" If the answer is yes, the resulting report should give you the information you need to manage asbestos effectively.

Dealing with Caveats and No-Access Areas

Caveats are exclusions -- things the surveyor is telling you they did not or could not inspect. They are one of the most significant issues in asbestos survey quality, and they deserve far more attention than they typically receive.

The Problem with Caveats

Many building managers only discover caveats when they read the survey report, buried in the appendices at the back. By that point, the surveyor has left site, and gaining access to excluded areas requires a return visit and additional cost.

Worse, any area that is not inspected must be presumed to contain asbestos until proven otherwise. A lift shaft listed as a no-access area effectively becomes an asbestos area, triggering additional risk assessments before lift engineers can enter. A riser duct excluded from the survey means every maintenance task involving that duct carries an asbestos presumption.

How to Minimise Caveats

Discuss exclusions before the survey begins, not after. At the point of commissioning:

1. Walk through the building with the surveyor and identify areas that may present access difficulties -- locked rooms, lift shafts, plant rooms, high-level areas, occupied spaces
2. Make arrangements in advance to provide access -- obtain keys, coordinate with lift maintenance contractors, arrange out-of-hours access if needed, provide access equipment
3. Agree the scope in writing -- confirm which areas will be surveyed and which (if any) will be excluded, along with the reasons
4. Set a target of zero caveats -- while some may be unavoidable (structural integrity concerns, genuine safety risks), the goal should be a comprehensive survey with minimal gaps

Common No-Access Areas and How to Address Them

Buildings Constructed After 1999

A frequently asked question: do post-2000 buildings need an asbestos survey?

The general position is that buildings constructed after 1999 (the year the final UK asbestos ban took effect) should not contain asbestos. CDM Regulations (in force since 1995) require as-built drawings and building manuals that document the materials used in construction.

If you have reliable construction records confirming the building date and materials used, a survey may not be necessary. However, be aware of two caveats:

1. Imported materials: A further ban in 2002 addressed plant and building materials imported from countries that had not yet banned asbestos. Materials from some European and international sources may have contained asbestos after 1999.
2. Refurbishment using older materials: If a post-2000 building has been refurbished using salvaged or stockpiled materials, ACMs could have been introduced.

The practical line is drawn at 1999/2000, but where there is any doubt about material origins, investigation is warranted.

Getting Maximum Value from Your Survey

To ensure your survey delivers the most useful data possible:

- Commission it with clear objectives. Are you managing an existing building, planning refurbishment, or both?
- Eliminate no-access areas proactively. Every caveat is a gap in your knowledge.
- Request the report in a format you can use -- not just a bound document, but data you can extract into your asbestos register and management plan
- Review the report critically. Are there unexplained presumptions? Areas marked as no-access that could have been reached? Generic recommendations that do not relate to specific findings?
- Remember: one management survey should be enough. If done properly, you should not need to repeat it. What you will need are re-inspections of identified ACMs and targeted R&D surveys before specific works.

Sampling: How It Should Be Done

When surveyors take samples of suspect materials, they are carrying out a form of non-licensable work. The regulations require that:

- Control measures are applied -- the area should be dampened, isolated where possible, and people moved away from the sampling location
- Samples are taken carefully -- using appropriate tools, not hammers or excessive force
- The surveyor wears appropriate RPE and PPE -- respiratory protective equipment and personal protective equipment should be worn for any sampling activity
- The air is cleaned afterwards -- fibre release must be minimised and any contamination addressed
- The sample point is sealed -- to prevent ongoing fibre release from the disturbance

If you observe a surveyor taking samples without any control measures, or using excessive force that creates visible dust or debris, raise this as a concern. Proper sampling technique is a basic indicator of surveyor competence.

Summary

The asbestos survey is your starting point, but its value depends entirely on how well it is scoped, executed, and applied. A survey full of caveats and no-access areas is a survey that leaves you guessing -- and guessing means presuming asbestos is present everywhere you did not look.

Invest the time upfront to brief the surveyor properly, provide full access, and agree clear expectations. The payoff is a comprehensive, reliable dataset that forms the foundation of your entire asbestos management system for the life of the building.
