The asbestos exclusion in professional indemnity insurance

What the asbestos exclusion actually does

Professional indemnity (PI) insurance covers claims that a client, or a third party, has suffered a financial loss because of your professional advice, design or service. An asbestos exclusion carves a specific hazard out of that promise: it tells the insurer not to pay any claim that arises out of, or is in connection with, asbestos or asbestos-containing materials.

The reach of the exclusion depends entirely on its drafting. A narrow clause might exclude only claims for bodily injury or property damage caused by asbestos fibres. A broad clause can exclude anything “directly or indirectly” connected to asbestos — which could catch a report that failed to flag it, advice that under-scoped a survey, or a project delay caused by unexpected asbestos on site. Two policies can carry the same headline exclusion and behave very differently in a claim.

Why insurers apply it

Asbestos sits in a category of risks that insurers find genuinely difficult to price and reserve. Three features drive the caution:

• Long-tail exposure. Asbestos-related disease can surface decades after exposure, so a claim may land on a policy written many years earlier and long since expired for accounting purposes.
• Aggregation. A single defective approach or missed material can generate many claims across many sites, stacking losses in a way that ordinary professional errors rarely do.
• Regulatory weight. Duties under the Control of Asbestos Regulations 2012, enforced by the Health and Safety Executive, mean the professional standard of care is high and failures are visible.

Because of this, asbestos is frequently treated as a “managed” peril — excluded by default, then partly restored where the insurer is comfortable with the applicant’s discipline and procedures.

Who is most affected

The exclusion bites hardest on professionals whose day-to-day work brings them into contact with buildings and materials:

• Building surveyors carrying out condition surveys, homebuyer reports and dilapidations work.
• Architects and engineers designing refurbishment or demolition where existing materials are disturbed.
• Environmental and asbestos consultants producing management surveys, refurbishment and demolition surveys or re-inspection reports.
• Project managers and building consultants co-ordinating works on older stock.

For a surveyor, this is not a fringe issue. If you inspect buildings constructed before the year 2000, asbestos-containing materials are a realistic possibility on almost any instruction, and a report that misses or mishandles them is exactly the sort of error a PI policy is meant to answer.

Full exclusion, write-back or heave restriction

Asbestos wordings tend to fall into a few recognisable shapes. Knowing which one you hold tells you where you stand.

The write-back version is the one most surveyors need. It accepts that you cannot avoid asbestos in your line of work, and keeps you insured for the professional judgement you are actually being paid for, while still excluding the raw exposure risk the insurer never intended to take on.

RICS and other professional requirements

If you are regulated by the Royal Institution of Chartered Surveyors (RICS), your PI cover must meet the RICS minimum policy wording and terms. That framework sets baseline requirements around limits, run-off and the treatment of certain exclusions, so an off-the-shelf policy bought without reference to it can leave you both under-insured and non-compliant. When you take asbestos-related instructions, check that your wording sits within your regulator’s requirements, not just within your budget.

How to protect yourself in practice

• Read the actual asbestos clause in your schedule — not the summary — and identify which of the four shapes above it takes.
• Match the wording to your real work. If you survey pre-2000 buildings, an absolute exclusion is a serious gap.
• Use clear terms of engagement that scope what your survey does and does not cover, and flag where a specialist asbestos survey is needed.
• Keep evidence of your inspection methodology and any caveats — it supports both a write-back and your defence in a claim.
• Disclose your asbestos-related activities honestly at proposal stage, so the cover you buy responds when you need it.

If any of this is unclear on your current schedule, that is exactly the point to speak to a broker before you renew rather than after a claim.

Common questions

Does every PI policy exclude asbestos?

No, but it is common for construction-related professions. The important question is not whether asbestos is mentioned, but whether the clause is absolute or writes back cover for your professional advice and reporting.

I’m a surveyor who never removes asbestos — do I still need cover for it?

Yes. You are not exposed for removing it, but you can be sued for failing to identify it, mis-scoping a survey or giving advice a client relied on. That professional error is the risk a write-back is designed to keep insured.

If I disagree with how a claim is handled, where can I turn?

Eligible policyholders can refer an unresolved complaint about an insurer to the Financial Ombudsman Service. That does not replace holding the right wording in the first place, which is where broker advice earns its keep.
