Asbestos survey costs before demolition or conversion
The Control of Asbestos Regulations 2012 require an intrusive survey before works disturb the fabric. Ordering the wrong survey type is the mistake that costs a month on a conversion.
Two different asbestos surveys exist and they cost different money because they do different work. A management survey locates material that could be disturbed during normal occupation. A refurbishment and demolition survey is fully intrusive, opens up the fabric, and is the one the Control of Asbestos Regulations 2012 require before you knock anything down or strip anything out. Landlords converting flats above shops order the first when they need the second, discover the mistake when the contractor opens a ceiling void, and lose a month.
Management survey against refurbishment and demolition survey
The distinction is set out in the Health and Safety Executive's survey guide, HSG264, which replaced the older type 1, 2 and 3 language in 2012. Some surveyors still use the old numbering in conversation, which is worth correcting at the quotation stage.
| Management survey | Refurbishment and demolition survey | |
|---|---|---|
| Purpose | Manage asbestos during normal occupation | Locate all asbestos before works disturb the fabric |
| Intrusion | Minimal, presumptions recorded where access is limited | Destructive, including voids, ducts, under floors and within structures |
| Occupation | Building can stay in use | Area must be vacated and certified fit for reoccupation afterwards |
| Presumptions | Acceptable, recorded as presumed or strongly presumed | Not acceptable in the work area, everything must be identified |
| When required | Ongoing duty to manage in non-domestic premises | Before refurbishment, strip-out or demolition |
A management survey that presumes asbestos in an inaccessible riser is doing its job. The same presumption in a demolition survey is a failure, because the whole point is to remove the uncertainty before a demolition contractor prices the job.
What the regulations actually require
Regulation 4 of the Control of Asbestos Regulations 2012 places a duty to manage asbestos on whoever has responsibility for maintenance and repair of non-domestic premises, including the common parts of blocks of flats. That duty is continuous and applies whether or not any work is planned.
Regulation 5 is the one that bites before a project. Before any work that is liable to expose employees to asbestos, a suitable and sufficient assessment must be made of whether asbestos is or is liable to be present, including its type and condition. For a building of any age that means a survey, because you cannot assess what nobody has looked for.
The regulations then split the work itself into licensed, notifiable non-licensed and non-licensed categories, with different notification, training, medical surveillance and record-keeping obligations. Licensable work requires a licensed contractor and notification to the Health and Safety Executive at least 14 days before it begins. That notice period alone has wrecked more programmes than the removal cost.
Under the Construction (Design and Management) Regulations 2015 the survey also feeds the pre-construction information. A client who hands a contractor a package without it has not discharged that duty.
Pricing the survey
Surveys are quoted on the building, not on a published rate, and the variables are consistent.
Floor area and the number of discrete rooms drive the time on site. Access drives it further, because a survey of an occupied flat above a trading shop needs evening or weekend attendance. Then comes the number of samples, each analysed by a laboratory, and the extent of making good after intrusive inspection, which on a refurbishment survey can mean patching ceilings and reinstating floor finishes in every room.
Ask three things of any quotation. That the surveying organisation is accredited or certificated for asbestos surveying, that analysis is carried out by an accredited laboratory, and that the price states how many samples are included and what additional ones cost. A quotation with an unlimited sample allowance is unusual, and a quotation that is silent on samples will grow.
Where the building is a former industrial or commercial unit, the asbestos survey usually sits alongside other pre-works investigation. Budget it in the same envelope as the contaminated land investigation programme rather than as a separate afterthought, because the two are often procured together and share site access costs.
When the survey finds something
Finding asbestos is normal in buildings constructed or refurbished before 2000. The question is what type, in what condition, and whether the works will disturb it.
Sheeting in good condition that will not be touched can often be managed in place and recorded. Insulating board in a ceiling you intend to remove cannot. Sprayed coatings and lagging are at the licensed end and bring the full apparatus of enclosure, negative pressure, air monitoring and a four stage clearance before reoccupation.
Three cost lines follow, and all three belong in the budget from the start:
- Removal by an appropriately licensed or trained contractor, priced by area and access rather than by weight.
- Disposal as hazardous waste, with consignment documentation, a licensed carrier and a permitted site.
- Clearance certification by an independent analyst before anyone returns to the area.
Record the disposal properly. Asbestos waste is hazardous waste, and the paperwork will be asked for by the Site Waste Management Plan or its equivalent on a scheme where one is required by condition.
How it fits with demolition consents
Asbestos sits outside planning permission but overlaps with two consents that people forget.
Demolition of most buildings needs prior approval under the General Permitted Development Order for the method of demolition and the restoration of the site. Separately, section 80 of the Building Act 1984 requires notice to the local authority before demolition begins, and the authority can serve a counter-notice imposing requirements. Both processes ask what will happen to the building, and an asbestos strategy is part of a credible answer.
Sequence the works accordingly. The refurbishment and demolition survey comes before the demolition method statement, not after, because the method depends on what has to come out first and under what controls.
Where a building is being stripped rather than demolished, a Pre-redevelopment Audit records what materials can be reused or recovered, and the asbestos register is the document that tells you which of them can safely be handled at all.
Budgeting the survey and the contingency
Treat the survey as a small cost buying information about a large one. The survey itself is a minor line. The removal, the programme delay and the clearance are the exposure.
Price the survey early, before exchange where possible, and make the result a condition of the purchase on a marginal deal. Carry a contingency scaled to the building's age and construction rather than a flat percentage, because a 1970s system-built block and a 1930s house present entirely different risks. And add float to the programme for the 14 day notification on licensed work, which cannot be shortened.
The same discipline applies to the other consents and connections that sit outside the planning fee, such as the utility connection costs in a development budget. See PlanScope pricing if you want the planning documents for the conversion drafted while the survey is being arranged.

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 may record presumptions where access is limited. A refurbishment and demolition survey is fully intrusive, opens up voids and structures, and must identify rather than presume. The area has to be vacated and certified fit for reoccupation afterwards.
Which regulations require an asbestos survey?
The Control of Asbestos Regulations 2012. Regulation 4 places a continuing duty to manage asbestos in non-domestic premises, including common parts of blocks of flats. Regulation 5 requires a suitable and sufficient assessment of whether asbestos is present before any work liable to expose employees, which in practice means a survey.
What drives the cost of an asbestos survey?
Floor area, the number of discrete rooms, access arrangements including out-of-hours attendance, the number of samples sent for laboratory analysis and the extent of making good after intrusive inspection. Ask any quotation to state how many samples are included and what additional ones cost, because that is where prices move.
How much notice does licensed asbestos removal need?
Licensable work requires a licensed contractor and notification to the Health and Safety Executive at least 14 days before it starts. That period cannot be shortened, so build it into the programme as float rather than treating it as administration. Enclosure, air monitoring and four stage clearance add further time before reoccupation.
Does the asbestos survey affect the demolition consent?
It informs it. Demolition of most buildings needs prior approval for the method of demolition and site restoration, and section 80 of the Building Act 1984 requires separate notice to the local authority. Both ask how the building will come down, so commission the refurbishment and demolition survey before the method statement is written.
