The legal basis for each survey type
The Control of Asbestos Regulations 2012 (CAR 2012) creates two distinct legal duties that each require a different type of survey.
Regulation 4 — the duty to manage — applies to the dutyholder of any non-domestic premises built before 2000. It requires them to identify ACMs present in the building, assess their condition and risk, and manage them in a way that protects anyone who may work on or in the building. A management survey is the instrument that fulfils this duty.
Regulation 5 applies before any refurbishment or demolition work that may disturb ACMs. It requires that an employer or self-employed person does not carry out such work unless a suitable survey of the premises has been carried out. A management survey does not satisfy this requirement — a refurbishment and demolition survey is required.
The most common mistake we see
A building owner commissions a management survey when planning a fit-out or renovation. The management survey is on file, so they assume it covers the building work. It does not. The management survey covers accessible areas under normal occupation — it does not investigate voids, service ducts, or areas that will be opened during the work. An R&D survey is required before any contractor begins.
Side-by-side comparison
| Aspect | Management Survey | R&D Survey |
|---|---|---|
| Purpose | Identify ACMs present during normal occupation; assess condition and risk | Identify all ACMs that may be disturbed by building work or demolition |
| Legal trigger | Regulation 4 CAR 2012 — duty to manage in non-domestic premises | Regulation 5 CAR 2012 — before any refurbishment or demolition work |
| Intrusive? | Minimally — accessible areas only, no destructive investigation | Fully intrusive — voids opened, floor coverings lifted, service ducts accessed |
| Sampling | Representative samples from accessible suspected ACMs | Comprehensive sampling of all areas affected by the planned work |
| Output | Asbestos register, risk ratings, management recommendations | Full ACM inventory for the work area; required before contractor mobilisation |
| Who needs it | Dutyholders of non-domestic premises built before 2000 | Anyone commissioning building work, renovation, or demolition |
| Frequency | Initial survey + periodic re-inspection (typically annual) | Before each discrete refurbishment or demolition project |
| Can it replace the other? | No — cannot substitute for an R&D survey before building work | No — does not fulfil the ongoing management duty under Regulation 4 |
What each survey involves in practice
Management Survey
The surveyor walks the building and inspects all accessible areas — rooms, corridors, plant rooms, roof spaces where safely accessible. Suspected ACMs are identified visually and by reference to known building materials of the era.
Bulk samples are taken from suspected materials and sent to a UKAS-accredited laboratory for analysis. The surveyor assesses the condition of each ACM — whether it is intact, damaged, or deteriorating — and assigns a risk priority score.
The output is an asbestos register and a set of management recommendations: leave in place and monitor, encapsulate, or remove. This forms the basis of the asbestos management plan.
The survey does not involve destructive investigation — no voids are opened, no floor coverings lifted, no service ducts accessed. Areas that cannot be accessed without causing damage are noted as presumed to contain ACMs.
Refurbishment & Demolition Survey
The R&D survey is fully intrusive. The surveyor investigates all areas that will be affected by the planned work — including voids above suspended ceilings, floor voids, service ducts, wall cavities, and any other areas that will be opened or disturbed.
This requires destructive investigation: ceiling tiles lifted, floor coverings peeled back, inspection hatches opened or created. The building or affected area must be vacated for the duration of the survey.
All suspected ACMs in the work area are sampled and analysed. The output is a comprehensive inventory of every ACM that may be disturbed by the work, with locations, quantities, and condition assessments.
This inventory is provided to the principal contractor before work begins. It is the legal basis for the contractor's method statement and risk assessment.
Which survey do you need?
Match your situation to the correct survey type.
You manage a commercial building built before 2000
→ Management Survey. Regulation 4 duty to manage requires you to identify and manage ACMs in normal occupation.
View serviceYou are planning a refurbishment, fit-out, or extension
→ Refurbishment & Demolition Survey. Any work that may disturb ACMs requires a fully intrusive R&D survey before contractors begin.
View serviceYou are demolishing a structure or part of a building
→ Refurbishment & Demolition Survey. Demolition requires the most comprehensive intrusive survey — all areas must be investigated.
View serviceYou have an existing management survey and need to re-inspect
→ Re-Inspection Survey. ACM condition changes over time. Annual re-inspection keeps your register current and your duty fulfilled.
View serviceYou want to check a specific material before disturbing it
→ Asbestos Testing & Sampling. If you know the material and location, targeted bulk sampling is faster and lower-cost than a full survey.

The Bermondsey fit-out: why a management survey on file was not enough
A facilities manager contacted us before a planned office fit-out in a 1970s Bermondsey building. The building had a management survey carried out two years earlier — it was current, well-documented, and showed ACMs in the plant room and one ground-floor corridor. The facilities manager assumed the survey covered the fit-out.
We explained that the management survey covered accessible areas under normal occupation. The fit-out involved removing a suspended ceiling on the second floor to expose the original concrete soffit — a void that had never been investigated. Before any ceiling tiles could come down, an R&D survey of the second-floor void was required.
We carried out the R&D survey. The void contained asbestos insulation board (AIB) on the original steel beams — a material that would have been disturbed the moment the first ceiling tile came down. The AIB was removed under controlled conditions before the fit-out contractor mobilised.
The fit-out proceeded on schedule. The facilities manager later told us that the R&D survey had cost less than one day of contractor downtime would have. The management survey was not wrong — it was simply the wrong instrument for the job.
The third type: re-inspection surveys
A management survey is a point-in-time assessment. ACMs deteriorate over time — through physical damage, water ingress, vibration, or simply age. CAR 2012 requires that the condition of known ACMs is monitored and that the asbestos register is kept up to date.
A re-inspection survey revisits known ACMs, checks their condition against the previous assessment, and updates the register. The frequency depends on the condition and risk rating of the ACMs — typically annual for materials in fair condition, more frequently for damaged or deteriorating materials.
Re-inspection surveys are a legal requirement for dutyholders, not an optional extra. An out-of-date register is a compliance failure under Regulation 4. See our guide to asbestos management plans for more on the ongoing management duty.
UKAS-accredited laboratory analysis
The HSG264 guidance (the HSE's definitive guide to asbestos surveys) requires that bulk samples collected during surveys are analysed by a UKAS-accredited laboratory. UKAS accreditation means the laboratory has been independently assessed against international standards for competence and impartiality.
We use a UKAS-accredited laboratory for all our survey work. Results are typically returned within five working days. We include the laboratory report in the survey documentation we provide to you.
