Which asbestos survey do I need

Start with the work, not the building

People ring me and open with the year the building went up. That tells me almost nothing on its own. What decides the survey is the scope of the work, because the survey exists to stop somebody putting a drill, a saw or a demolition attachment through asbestos that nobody looked for. Tell me you are keeping the place occupied and changing nothing, and we are managing what is there. Tell me you are stripping a suspended ceiling and chasing new cables through stud walls, and we are opening those walls up before your electrician does.

HSG264 sets out two survey types: management, and refurbishment or demolition. Refurbishment and demolition get talked about as separate jobs on site because the amount of destruction differs enormously, but they sit in the same category in the guidance. Re-inspection and single-sample testing are useful, and neither one substitutes for the survey the work itself requires.

Management survey

This is the baseline for a non-domestic building that is occupied and staying that way, and for the common parts of blocks of flats. It finds what could be disturbed during normal use and foreseeable maintenance, and it feeds your asbestos register and management plan. It is not a gentle walk round with a torch. A surveyor doing it properly is lifting ceiling tiles, opening risers and hatches, getting into ducts and plant rooms, and taking samples where a material needs confirming.

Where it goes wrong is in the caveats. I have read management surveys with half the building listed as no access and a client who thought that meant clear. It does not. Anywhere not inspected has to be presumed to contain asbestos until somebody proves otherwise.

Refurbishment survey

Project specific, intrusive, and designed around drawings rather than around the building. If the spec says new partitions on the second floor, the survey covers the second floor partitions, the voids above them, the floor construction below, and the service routes feeding them. Insulating board behind an electrical intake, AIB partition linings, textured coating on a ceiling that is coming down: these are the things that stop a job dead if you find them on the Tuesday of week one instead of before you priced it.

Get the design far enough along that the surveyor can see the boundary. If the scope grows later, and it usually does, the new areas need surveying before anyone touches them.

Demolition survey

Fully intrusive, destructive, and done in an empty building with services isolated. The surveyor goes under floors, behind linings, into wall cavities and inside plant. This is the one where damage to the building is the point, because the building is going anyway.

Re-inspection

A condition check on materials already in the register. Not a new survey, not a substitute for one. It tells you whether the sealed AIB panel in the riser is still sound or whether somebody has put a fixing through it since last year.

Sampling and testing

One material, one question, laboratory answer. Right for the ceiling coating you are about to scrape and nothing else. Wrong for anything where you need to know what is in the rest of the building.

No one identifies asbestos from a photograph, and neither do I. A surveyor can presume a material where sampling is not undertaken, but confirmation means analysis by a laboratory accredited by UKAS for asbestos identification under ISO/IEC 17025. HSE strongly recommends using a UKAS-accredited inspection body for the surveying itself, though that is a recommendation rather than a blanket legal requirement.

The five calls I make most often

Buying a house

No law says a homebuyer must commission an asbestos survey, and a standard building survey is not an HSG264 survey. If you are buying a 1970s semi and living in it as it stands, you are managing, not surveying: know where the Artex, the garage roof and the boiler flue are, and leave them alone. If you have already booked the kitchen fitter, that is a refurbishment survey of the kitchen, not a general look round.

Landlord letting a property

The Regulation 4 duty to manage covers non-domestic premises and the common parts of multi-occupancy domestic premises. It does not reach into the private interior of a single let dwelling just because it is rented. The communal stairwell, the plant room and the bin store are a different matter, and that is where a management survey earns its money. Send a contractor in to disturb the fabric and other duties bite regardless.

Office refit

An existing management survey will not carry an intrusive refit, and I have watched principal contractors try. Refurbishment survey, covering every affected room, ceiling void, partition, floor, riser and service route. In a 1960s or 1970s office block the usual finds are AIB ceiling tiles and column casings, thermoplastic floor tiles bedded in black bitumen, and insulation on old pipework in the risers.

Demolishing a garage

Prefabricated sectional garages are almost a textbook case: cement sheet roof, cement wall panels, sometimes a cement flue or gutter. Built or refurbished before 2000 and coming down entirely, that is a demolition survey covering roof, panels, linings, boards and anything concealed in the structure. Sampling the roof sheet alone answers one sheet and leaves the demolition contractor blind for the rest.

One suspect ceiling

Targeted sampling is proportionate here provided nothing wider is planned. Whoever takes it picks a representative point, controls the fibre release locally and makes the point good afterwards. The certificate covers the material that went in the pot. It says nothing about the identical-looking ceiling in the next room, which in my experience is frequently a different product from a different decade.

Age, and why 2000 is not a free pass

HSE advises that asbestos may be present in any building built or refurbished before 2000. Blue and brown asbestos were banned in 1985 and chrysotile followed at the end of 1999, so a building constructed wholly after 2000 is unlikely to contain asbestos in its original fabric.

Wholly is the word doing the work. I have surveyed plenty of premises where a 2004 extension is bolted onto a 1968 original, where a modern unit reused an older frame, or where the shell is new and the retained plant is not. A construction date is evidence about a specific building and a specific work area, not an exemption for the site. Where the records genuinely stand up and cover the areas being disturbed, a survey may be unnecessary for that scope. Where the history is mixed or the paperwork is thin, appearance is not going to settle it.

Reports, and the part clients skip

Read the scope and the limitations before you read the findings. A good report tells you what was inspected, what was found or presumed, what condition it is in, what could not be reached, and what to do about it. A caveat is a flag, not a clearance. If the report says no access to the floor void and your programme says lift the floor, you have a gap to close before anyone starts.

The survey is information for planning. It is not authority to remove anything, and it does not complete the duty to manage. That still sits with the dutyholder: assess the risk, keep the register current, tell the people who need to know, and review it.

Where the duty comes from

The duty to manage asbestos in non-domestic premises and the common parts of domestic premises is a legal requirement under Regulation 4 of the Control of Asbestos Regulations 2012. Employers must also assess the risk before work liable to disturb the fabric begins.

HSG264 is HSE guidance on planning and carrying out surveys. Following it is a recognised way of producing suitable information, but the duties themselves come from the Regulations. One distinction is worth holding onto: using a UKAS-accredited surveying body is strongly recommended by HSE, while an employer who has material analysed for asbestos must use a laboratory accredited for that analysis under the applicable statutory requirements.
