BOHS P402 — Asbestos Surveying
A surveyor sells independence; the qualification is the entry ticket
What P402 is
P402 is the BOHS qualification for professionals conducting asbestos surveys — management surveys and refurbishment and demolition surveys. It is the qualification expected of anyone carrying out or overseeing those surveys under the Control of Asbestos Regulations 2012.
It costs around £900, which is largely the course: typically five days with an approved training provider, followed by a written examination and a practical assessment. Unlike many schemes here, there is no annual renewal fee, but certified status has to be revalidated every five years.
It is a personal qualification. The person holds it, not the company, and the person is what the client is relying on.
Why the surveyor’s position is unusual
A surveyor finds the problem and reports on it. Somebody else, usually, removes it. That separation is the whole commercial and ethical shape of the work.
A surveyor whose business also does removal has a built-in conflict: the incentive to find more, or describe it as worse, is obvious to any client. The surveyor with nothing to sell beyond the survey has the reverse selling point. They can say, truthfully, that their recommendation is not shaped by what it will cost them to do next.
That is worth far more than the certificate. Property managers, solicitors and surveyors who commission asbestos surveys regularly are acutely aware of the question, and a firm that answers it in its first paragraph has already removed the biggest doubt.
Because the qualification is shared by every competent surveyor, independence and quality of reporting become the points of difference.
What the qualification requires
-
The P402 training course.
An accredited course from an approved provider, typically five days. Evidence: the booking confirmation.
-
The written and practical assessment.
Pass the BOHS examination and practical. Evidence: the P402 certificate from BOHS.
-
A UKAS-accredited laboratory.
Every sample must be analysed by one. Evidence: an agreement with the lab.
-
Professional indemnity insurance
Covering asbestos surveying. Evidence: the certificate.
What you have to keep doing
Annual CPD in asbestos regulation, sampling and risk assessment.
Revalidation with BOHS every five years to maintain certified status.
The report is the deliverable
Clients do not buy a certificate of qualification; they buy a report, and they buy it because someone else is going to read it. The contractor planning refurbishment reads it to decide where not to drill. The solicitor reads it for the sale. The duty holder reads it to meet their legal obligation to manage the asbestos in their building.
So the report is both product and defence. It has to be clear enough for a non-specialist, specific about locations and materials, honest about areas that could not be accessed, and traceable to laboratory results from a UKAS-accredited lab.
Professional indemnity matters for the same reason. A missed material is not a cosmetic error, it can mean a worker disturbing fibres later. The cover exists because the consequences travel a long way beyond the survey itself.
For marketing, the opportunity is to show a redacted sample report on the site. A procurement manager comparing three surveyors learns more from one page of a real report than from a list of credentials, and it sets a standard for the others to match.
The mistakes we see most
-
Not stating independence.
If you do not also remove, say so — it is the strongest point you have.
-
Letting revalidation lapse.
The five-year clock is easy to lose.
-
Reports that read like lab output.
The readers are not specialists.
-
Hiding the sample report.
A real example does more than any badge.
Where this lands in Gaffer
Surveys are recorded against the property with samples, lab results and the report attached, so the evidence behind a finding is held with the job.
Each surveyor’s P402 date, revalidation date and CPD sit against the person, so a lapse is visible years before it matters.
The three buyers and what each wants
Asbestos survey work is commissioned by three groups, and a surveyor who understands them writes better pages.
Property managers and duty holders need a management survey to meet their legal duty. They want it done on time, at a predictable price, with a report they can file and update. They tend to repeat.
Contractors and project teams need refurbishment and demolition surveys before work starts. They want speed, because the programme is waiting, and precision about where the material is, because that is what decides the method.
Private buyers and their solicitors are commissioning a survey because of a transaction. They want clarity from a document they did not expect to be reading.
Each audience has a different question, a different deadline and a different tolerance for jargon. A single page addressed to all three tells none of them that you understand their situation, whereas three short sections do.
Why turnaround is part of the quality
In most trades a quick turnaround is a convenience. In surveying it is part of the product, because the survey is usually blocking something else: a refurbishment start date, a house sale, a lease event.
Laboratory analysis sets the floor, since samples must go to a UKAS-accredited lab and the result cannot be rushed past a certain point. What the surveyor controls is everything around it: how quickly the site visit is booked, how promptly samples are sent and how soon the report is issued once results arrive.
Being honest about that timeline on the site is itself a selling point. A page that says what the typical sequence is, and where the lab time falls, helps the client plan and shows an understanding of their position.
Firms that do this well are rarely the cheapest. They are the ones a project manager phones first, because they know that the report will arrive when promised.
Choosing the training provider
The course is the main cost, and providers differ. Ask how much of the five days is spent on practical sampling and report writing, how big the groups are and what support there is for the practical assessment.
Ask also about revalidation: whether the provider offers refreshers, how they track your five-year date and what the CPD route looks like. A provider who supports you after the certificate is worth more than one who is merely cheaper on the first week.
Finally, ask recent attendees. Surveyors who have done it recently will tell you more about the course than any brochure.
Questions asbestos surveyors ask
How long is the training? Typically five days with an approved provider.
Does P402 renew annually? There is no annual fee, but BOHS revalidation is required every five years.
Who analyses the samples? A UKAS-accredited laboratory.
Can I survey and remove? The regulations do not stop you, but clients often prefer a surveyor with no stake in the removal.
