Costing an asbestos refurbishment and demolition survey
Access and making good drive the cost of a refurbishment and demolition survey, not the sample count. It also sits ahead of every other intrusive appointment on the programme.
Refurbishment demolition survey cost is driven by access and making good far more than by the number of samples. A surveyor lifting floors, drilling through linings, opening risers and then reinstating what they opened is on site for days rather than hours, and on an occupied building the work usually happens out of hours. Developers who price it as a sampling exercise get a surprise.
The survey is also a legal precondition rather than a nice to have. The Control of Asbestos Regulations 2012 require a suitable and sufficient assessment of whether asbestos is present before any work liable to disturb it begins.
Why the survey precedes any intrusive work
No intrusive work can start until the asbestos position is known. That includes opening up for a structural appraisal, service strip-out, trial holes through floor slabs and removing a suspended ceiling to measure a void.
The practical consequence is that the asbestos survey sits ahead of several other appointments on the programme, and scheduling it late blocks them all. On a refurbishment of a 1960s or 1970s building the survey often reshapes the scheme, because asbestos insulating board behind panels and in riser linings is expensive to remove and the removal needs an enclosure.
It is not a planning document. It belongs to the construction programme and to the duties under the construction design and management regulations, and it feeds the pre-construction information the principal designer issues.
Management survey against refurbishment and demolition survey
These are two different products and buying the wrong one is the most common error.
A management survey locates asbestos that could be disturbed during normal occupation and maintenance. It is minimally intrusive, it does not require the building to be vacated, and it supports the duty to manage asbestos in non-domestic premises. It is not sufficient before refurbishment or demolition.
A refurbishment and demolition survey is fully intrusive and destructive within the area affected. It is designed to locate all asbestos before the work starts, which means getting into voids, behind linings, under floors and inside plant. The area surveyed normally has to be vacated, and the surveyor will leave holes.
| Factor | Management survey | Refurbishment and demolition survey |
|---|---|---|
| Intrusion | Minimal | Full and destructive |
| Occupation | Building stays in use | Area vacated |
| Purpose | Managing asbestos in situ | Before refurbishment or demolition |
| Making good | Little or none | Significant element of the cost |
| Output | Register and management plan | Location, extent and condition for removal planning |
A management survey already on file is useful background. It does not discharge the duty before works.
The survey scope also has to match the works scope. A survey of the ground floor does not cover a scheme that later extends to the first floor, and surveyors scope tightly because the liability runs with the report. Define the area in writing, with a marked-up plan, before the surveyor attends.
What drives the fee
Six things, roughly in order of weight.
Floor area and the number of discrete rooms, since each one is a separate inspection. Access: scaffolding, mobile towers, confined space entry and roof access all add days. The extent of opening up and the standard of making good required, which on an occupied building can exceed the survey cost itself. Sample numbers and laboratory analysis, which must come from an accredited laboratory. Out-of-hours or phased working where the building stays partly occupied. And the building's age and construction type, because a steel-framed building of the right vintage needs encasement checked at every column.
The item most often omitted from a quotation is reinstatement. Ask explicitly whether making good is included and to what standard.
Licensed, notifiable and non-licensed work
Once the survey is in, the removal strategy follows from what was found.
Higher-risk materials, including sprayed coatings, lagging and most work with asbestos insulating board, require a licensed contractor working under an enclosure with controlled access and air monitoring. That is the expensive category and it governs the programme.
Some lower-risk work is notifiable non-licensed work, which does not need a licence but does need notification to the enforcing authority, medical surveillance for the operatives and records kept. The remainder is non-licensed work, typically short-duration work on asbestos cement or textured coatings.
Classification is a judgement about the material, its condition and the work being done, not just about the material type. A contractor who classifies everything as non-licensed to win a price is a risk rather than a saving.
Notification periods and clearance
Licensed removal has to be notified to the enforcing authority in advance of work starting, and the statutory notice period is a fixed calendar item that cannot be compressed. Build it into the programme at the point the survey results arrive, not when the contractor is appointed.
After licensed removal inside an enclosure, a four-stage clearance procedure by an independent accredited analyst is required before the enclosure comes down, and a certificate of reoccupation is issued. Each stage takes time and a failed clearance means cleaning and repeating it.
Asbestos waste is hazardous waste, requiring consignment documentation and disposal at a permitted site, which is a separate cost line from the removal itself. Double-bagged, labelled, and carried by a registered carrier to a site permitted to accept it. The gate fee is weight-based, so a building with widespread asbestos cement sheeting generates a disposal bill out of proportion to the removal labour.
Where it meets the pre-redevelopment audit
A pre-demolition materials audit identifies what can be reused or recycled before demolition, and asbestos is one of the things it has to screen out of the reusable stream. A Pre-redevelopment Audit and the asbestos survey should be commissioned together, because both involve the same site visits and the same access arrangements.
The demolition method statement, the Construction Management Plan submitted to discharge a planning condition, and the waste documentation all draw on the same survey. Running them off one set of findings avoids the contradiction a case officer will otherwise spot.
Where the survey changes the programme
Three outcomes change a demolition or refurbishment programme materially.
Widespread asbestos insulating board, which brings licensed removal, enclosures, notification periods and clearance testing into the critical path.
Asbestos found in structural encasement, which can mean removal has to happen in sequence with temporary works rather than as a single enclosure.
Asbestos discovered after strip-out that the survey missed, usually because an area was inaccessible at survey stage. The survey report should list every area it could not reach, and the programme should carry a provisional sum and a float for that list. Where the report has no caveats section on a complex building, treat that as a warning rather than as reassurance.
Budget the survey, the removal, the clearance and the disposal as four separate lines. Other preliminaries behave the same way, and building control charges alongside the planning fee are worth budgeting on the same basis.

Frequently asked questions
What is the difference between a management survey and a refurbishment and demolition survey?
A management survey locates asbestos that could be disturbed during normal occupation and maintenance, with minimal intrusion and the building still in use. A refurbishment and demolition survey is fully intrusive within the affected area, requires it to be vacated, and is designed to find all asbestos before work starts. The first does not substitute for the second.
What makes the survey expensive?
Floor area and the number of discrete rooms, access arrangements such as scaffolding or confined space entry, the extent of opening up and the standard of making good required, sample numbers and accredited laboratory analysis, out-of-hours working on an occupied building, and the construction type. Making good is the item most often left out of a quotation.
When does removal need a licensed contractor?
For higher-risk materials including sprayed coatings, lagging and most work with asbestos insulating board. Licensed work requires an enclosure, controlled access, air monitoring, advance notification to the enforcing authority and a four-stage clearance by an independent accredited analyst before the enclosure is taken down.
Does the notification period affect the programme?
Yes. Licensed removal must be notified to the enforcing authority in advance of work starting, and that notice period is a fixed calendar item that cannot be compressed. Build it into the programme when the survey results arrive rather than when the removal contractor is appointed, or it becomes dead time on site.
What if asbestos is found after strip-out?
It happens, usually in areas the survey could not reach. The report should list every inaccessible area explicitly, and the programme should carry a provisional sum and some float against that list. A report on a complex building with no caveats about access should be treated as a warning rather than as reassurance.
