What Is a Refurbishment Survey — and Why Does Every Building Project Need One?
Before a single wall comes down or a pipe gets ripped out, there is one question every contractor and building owner must answer: is there asbestos in the way? A refurbishment survey exists to answer exactly that — and getting it wrong can halt a project, endanger workers, and land duty holders in serious legal trouble.
If your building was constructed or refurbished before the year 2000, asbestos-containing materials (ACMs) could be hiding almost anywhere. Artex ceilings, pipe lagging, floor tiles, roof panels — the list is long. A refurbishment survey is the legally required method for finding them before intrusive work begins.
What Exactly Is a Refurbishment Survey?
A refurbishment survey is an intrusive, destructive inspection of a building — or a defined part of it — carried out before any refurbishment or maintenance work that could disturb the fabric of the structure. It is defined and governed by the HSE’s guidance document HSG264, which sets out how asbestos surveys must be planned, conducted, and reported.
Unlike a management survey — which is designed to locate ACMs in their normal, undisturbed state — a refurbishment survey goes considerably further. Surveyors must access all areas where work will take place, including inside walls, above suspended ceilings, beneath floors, and within service ducts. That means some degree of physical intrusion is unavoidable and expected.
The survey must also cover the full scope of the planned works. If the work scope changes mid-project, the survey must be revisited accordingly.
When Is a Refurbishment Survey Required?
The Control of Asbestos Regulations places a clear legal duty on those responsible for non-domestic premises to manage asbestos. When refurbishment or maintenance work is planned that will disturb the building fabric, a refurbishment survey is required before that work starts — not during it, and certainly not after.
Common triggers for a refurbishment survey include:
- Office or commercial fit-outs
- Electrical rewiring or plumbing upgrades
- Removal or installation of partitions
- Ceiling or floor replacement
- Heating system upgrades
- Loft conversions or structural alterations
- Installing new IT infrastructure through existing walls or ceilings
Even relatively minor works — like drilling into a wall to fix a bracket — can disturb ACMs if the building is old enough. If there is any doubt, a refurbishment survey removes that doubt before someone gets exposed.
Refurbishment Survey vs Management Survey vs Demolition Survey
Refurbishment Survey vs Management Survey
A management survey is the standard survey used to manage asbestos in an occupied building during its normal use. It is less intrusive and designed to locate ACMs that could be disturbed during routine maintenance or day-to-day activity.
A refurbishment survey is more thorough. It is designed for situations where the structure itself will be opened up. The two surveys serve different purposes, and a management survey does not satisfy the legal requirement before refurbishment work begins — this is one of the most common and costly mistakes project managers make.
Refurbishment Survey vs Demolition Survey
If a building is being fully or partially demolished rather than refurbished, a demolition survey is required instead. This is the most intrusive type of survey, designed to locate all ACMs throughout the entire structure before demolition takes place.
The key distinction is scope. A refurbishment survey covers the area of planned works, while a demolition survey must cover the whole building without exception.
How Is a Refurbishment Survey Carried Out?
A refurbishment survey must be carried out by a competent surveyor — someone with the appropriate training, experience, and knowledge of where ACMs are likely to be found and how to sample them safely. Here is what the process looks like in practice.
Step 1: Scoping the Survey
Before the surveyor sets foot on site, the scope of the planned works must be clearly defined. The building owner or principal designer should provide full details of the refurbishment scope so the surveyor can plan accordingly. The survey is built around what is going to be disturbed — nothing more, nothing less.
Step 2: Intrusive Inspection
The surveyor will physically access all areas within the scope of works. This includes breaking into walls, lifting floor coverings, opening service risers, and inspecting above ceiling tiles. Any area that will be touched during the refurbishment must be inspected.
Surveyors take bulk samples from materials suspected to contain asbestos. These samples are sent to an accredited laboratory for analysis using polarised light microscopy or similar techniques.
Step 3: Laboratory Analysis
Samples are analysed at a UKAS-accredited laboratory to confirm whether asbestos is present and, if so, which type. The three types found in UK buildings are chrysotile (white asbestos), amosite (brown asbestos), and crocidolite (blue asbestos) — all of which are hazardous and all of which have been used extensively in building materials.
Step 4: The Survey Report
The surveyor produces a detailed written report containing:
- The location of all identified or presumed ACMs
- The type and condition of each material
- An assessment of the risk each material presents
- Photographs and annotated floor plans
- Laboratory certificates for all samples taken
- Recommendations for management or removal
This report becomes a critical document for the project. Contractors must be given access to it before work starts, and it should be passed to the principal designer under CDM regulations.
Legal Duties Under the Control of Asbestos Regulations
The Control of Asbestos Regulations applies to all non-domestic premises and places clear duties on duty holders — typically the building owner, employer, or anyone with responsibility for the maintenance and repair of the premises.
Under these regulations, duty holders must:
- Take reasonable steps to find out if ACMs are present before any work that could disturb them
- Presume materials contain asbestos unless there is strong evidence to the contrary
- Ensure a refurbishment survey is carried out before relevant works begin
- Share the survey findings with all contractors working on site
- Ensure that identified ACMs are either properly managed or removed by a licensed contractor before work proceeds
Failure to comply can result in prohibition notices, improvement notices, and prosecution by the HSE. Fines and custodial sentences have been handed down in serious cases. The law is not ambiguous on this point.
The Role of CDM Regulations
The Construction (Design and Management) Regulations place additional duties on principal designers and principal contractors to ensure that asbestos risks are identified and managed during the pre-construction phase.
The refurbishment survey report feeds directly into the pre-construction health and safety information that must be prepared and shared before work begins. Principal designers must review the survey findings and ensure the project design takes account of any ACMs identified. Contractors must not begin work in areas where asbestos is present until it has been properly dealt with.
What Happens When Asbestos Is Found?
Finding asbestos during a refurbishment survey does not automatically stop a project. It does, however, require a clear plan of action before work in that area can proceed.
Depending on the type, condition, and location of the ACMs found, the options are:
- Removal before works begin — the most common approach when ACMs are in the direct path of refurbishment activity
- Encapsulation — sealing or enclosing ACMs so they cannot release fibres, where removal is not immediately necessary
- Leaving in place with controls — only appropriate where materials are in good condition and will not be disturbed
Where removal is required, this must be carried out by a licensed asbestos contractor in most cases. The asbestos removal process involves setting up a controlled enclosure, using negative pressure units to prevent fibre release, and disposing of all waste as hazardous material at a licensed facility.
Only once the area has been cleared and passed a four-stage clearance procedure — including a thorough visual inspection and air testing — can refurbishment work safely proceed.
Who Needs a Refurbishment Survey?
Any building owner, facilities manager, or contractor planning work in a building constructed before 2000 should arrange a refurbishment survey before work begins. This applies across all sectors:
- Commercial offices and retail premises
- Schools, hospitals, and public buildings
- Industrial units and warehouses
- Residential flats and houses of multiple occupation (HMOs)
- Hotels and leisure facilities
- Historic and listed buildings
It is worth noting that domestic properties are not covered by the Control of Asbestos Regulations in the same way as non-domestic premises. But that does not mean asbestos in a home is any less dangerous. Any contractor working in a domestic property built before 2000 still has a duty of care to their own workers and must take appropriate precautions.
Common Mistakes to Avoid
Even experienced project managers can fall into avoidable traps when it comes to refurbishment surveys. These are the most common mistakes we see:
- Relying on an existing management survey — a management survey does not meet the legal requirement before refurbishment work. A separate refurbishment survey is always needed.
- Surveying too narrow a scope — if the works change after the survey, the survey must be updated. Do not assume the original report still covers everything.
- Not sharing the report with contractors — all workers on site must be made aware of the survey findings before work begins. Keeping the report in a drawer achieves nothing and creates legal liability.
- Assuming newer-looking buildings are safe — some buildings were refurbished with asbestos materials well into the 1980s and 1990s. Age alone is not a reliable guide.
- Starting work before the report is complete — laboratory results take time. Build the survey into your project timeline from the outset, not as an afterthought.
How Much Does a Refurbishment Survey Cost?
The cost of a refurbishment survey depends on the size of the building, the complexity of the works, and the number of samples required. For a small commercial unit, a survey might cost a few hundred pounds. For a large multi-storey building with a wide scope of works, the cost will be considerably higher.
What is worth keeping in mind is the cost of not having one. A single enforcement notice from the HSE, an unplanned project shutdown, or the cost of emergency asbestos removal once work has already started will far exceed the cost of a properly planned survey. The survey is not an overhead — it is risk management, and it protects everyone on site.

Frequently Asked Questions
What is the difference between a refurbishment survey and a management survey?
A management survey is used to manage asbestos in an occupied building during normal use. It is non-intrusive and designed to locate ACMs that could be disturbed during routine activity. A refurbishment survey is more thorough and intrusive — it is required before any work that will disturb the building fabric, such as opening walls, lifting floors, or replacing ceilings. A management survey does not satisfy the legal requirement before refurbishment work begins.
Is a refurbishment survey a legal requirement?
Yes. Under the Control of Asbestos Regulations, a refurbishment survey is legally required before any work in non-domestic premises that could disturb the building fabric. The duty holder — typically the building owner or employer — is responsible for ensuring the survey is carried out before work starts. Failure to do so can result in enforcement action, fines, or prosecution by the HSE.
How long does a refurbishment survey take?
The duration depends on the size of the building and the scope of the planned works. A small commercial unit might be surveyed in a few hours, while a large or complex building could take a full day or more. Laboratory analysis of samples typically takes a few working days. You should factor the full survey and reporting timeline into your project programme from the outset.
Can refurbishment work start while the survey is being processed?
No. Work must not begin in any area covered by the survey until the report is complete and the findings have been reviewed. If ACMs are identified, they must be managed or removed by a licensed contractor and the area must pass a four-stage clearance procedure before work can proceed. Starting work before results are confirmed puts workers at risk and exposes duty holders to serious legal liability.
Do domestic properties need a refurbishment survey?
Domestic properties are not covered by the Control of Asbestos Regulations in the same way as non-domestic premises. However, any contractor working in a domestic property built before 2000 still has a duty of care to protect their workers from asbestos exposure. A refurbishment survey is strongly advisable before any intrusive work in older domestic buildings, and many responsible contractors will insist on one before starting.
