A Bristol-headquartered property managing agent is renewing its professional indemnity programme on 1 October. Twelve months earlier, one of its surveyors was the subject of an informal Royal Institution of Chartered Surveyors enquiry that ended without action. There is no live complaint, no claim, and no civil proceeding. The finance director’s view is that “nothing happened, so there is nothing to disclose.” The broker’s view is less certain. The underwriter’s view, if the matter ever came to light after a claim, will turn on a single statutory test: was the enquiry a material circumstance within the meaning of s.7(3) of the Insurance Act 2015?
This article explains the material circumstance test in the detail it deserves. We work through s.7(3) and s.7(4), the carry-over of the Pan Atlantic inducement requirement into the Schedule 1 remedies regime, the interaction with the s.3(4)(b) “signposting” route, and the principal post-Act case law. We close with the materiality flashpoints we see most often in practice and the broker-side discipline that helps insureds get the call right at placement.
The statutory test: s.7(3) and s.7(4)
Section 7 of the Insurance Act 2015 defines the key terms used in the disclosure provisions. Two subsections do the heavy lifting.
s.7(3): the prudent insurer test
Section 7(3) provides:
A circumstance or representation is material if it would influence the judgement of a prudent insurer in determining whether to take the risk and, if so, on what terms.
Three features of the test are worth pausing on:
- “Influence the judgement” — not “decisively influence” or “determine.” The test is satisfied if the prudent insurer would take the matter into account.
- “A prudent insurer” — an objective, hypothetical standard. The actual insurer’s idiosyncrasies (a particularly cautious underwriter, or one with a niche risk appetite) are addressed at the second stage, inducement.
- “Whether to take the risk and, if so, on what terms” — materiality is binary as to disclosure but covers both the underwriting decision and the terms (premium, limit, deductible, conditions, exclusions). Something which would only have caused a 5% premium uplift is still material.
s.7(4): the non-exhaustive list of examples
Section 7(4) provides a useful (but non-exhaustive) list. Examples of things which may be material circumstances include:
- (a) special or unusual facts relating to the risk;
- (b) any particular concerns which led the insured to seek insurance cover for the risk; and
- (c) anything which those concerned with the class of insurance and field of activity in question would generally understand as being something that should be dealt with in a fair presentation of risks of the type in question.
Paragraph (c) is, in our view, the most useful in practice. It anchors materiality in market understanding. If brokers and underwriters in a particular sector — D&O, cyber, contractors’ all-risks, marine cargo — would generally expect a particular topic to be addressed at placement, then it is material. That is a workable real-world test.
The continuing relevance of Pan Atlantic
The leading pre-Act authority on materiality, Pan Atlantic Insurance Co Ltd v Pine Top Insurance Co Ltd [1995] 1 AC 501, remains essential reading. The House of Lords held two things which the 2015 Act has carried forward, in modified form, into the statutory scheme:
- The materiality test is the “would influence” test — a prudent insurer’s mind would be influenced, not necessarily decisively. Section 7(3) adopts this formulation.
- Materiality alone is not enough; the actual insurer must in fact have been induced to write the risk (or write it on the terms it did) by the misrepresentation or non-disclosure. This is the inducement requirement.
The 2015 Act does not state the inducement requirement in s.3 or s.7. It is built into the Schedule 1 remedies regime. The remedies in Sch 1 are only available where the insurer can show that, but for the breach, it would not have entered into the contract at all, or would have done so only on different terms. Without inducement, there is no remedy, however material the undisclosed circumstance.
The post-Act position therefore remains a dual test:
- Objective materiality (s.7(3)) — would a prudent insurer’s judgement have been influenced?
- Actual inducement (Schedule 1) — was this insurer in fact induced?
The interaction with s.3(4)(b)
A circumstance can be material without the insured being required to disclose it in full. Section 3(4)(b) permits the insured to make a fair presentation by providing sufficient information to put a prudent insurer on notice that it needs to make further enquiries.
The materiality question and the disclosure question are therefore distinct:
- s.7(3) determines whether a circumstance is material.
- s.3(4) determines how material circumstances must be presented — either by full disclosure (s.3(4)(a)) or by sufficient signposting (s.3(4)(b)).
A common practical pattern is for an insured to disclose the existence of a regulatory enquiry, the regulator involved, the broad subject matter and the current status, while declining to provide privileged advice or full case papers. That can be a perfectly proper use of s.3(4)(b): it puts the underwriter on notice and invites a follow-up question, while preserving privilege.
Key post-Act case law
The English courts have now considered the material circumstance test on several occasions. Four cases are particularly worth understanding.
Berkshire Assets (West London) Ltd v AXA Insurance UK Plc [2021] EWHC 2689 (Comm)
Berkshire Assets is the most cited post-Act materiality decision and is essential reading for any broker placing risks for insureds with directors or shareholders facing regulatory or criminal enquiries.
The claimant company was insured under a property policy with AXA. A director and indirect shareholder was charged in Malaysia with offences relating to misappropriation of public funds in connection with what became known as the 1MDB scandal. After a fire loss, AXA avoided the policy on the basis that the charges had not been disclosed.
The court held that the charges were a material circumstance. Of particular note:
- The materiality test under s.7(3) is whether the matter would influence the prudent insurer’s judgement, not whether it would be decisive.
- Moral hazard — including matters affecting the integrity of those who control or significantly influence the insured — is capable of being material even on a property risk.
- The fact that the director was not himself the proposer, and that the charges were extraterritorial and contested, did not displace materiality.
- AXA was able to establish inducement on the evidence.
The case is a clear modern statement that materiality is a broad concept and that regulatory and criminal matters affecting controllers are routinely going to be in scope.
ABN AMRO Bank NV v Royal & Sun Alliance Insurance Plc and others [2021] EWCA Civ 1789
The ABN AMRO litigation is the principal post-Act Court of Appeal decision on the construction of a complex commercial cover (a marine cargo policy extended to provide credit-style protection in respect of cocoa transactions). It is frequently cited for general principles of policy construction and indemnity in modern commercial covers.
For materiality and disclosure purposes, the case is relevant in two ways. First, the Court’s approach to construction emphasises that the parties’ contract is to be read as a whole and against its commercial context — which informs what a reasonable underwriter would expect to see disclosed in similar covers. Second, the case illustrates the modern courts’ willingness to give effect to bespoke commercial wordings that depart from market norms, which sharpens the broker-side obligation to ensure such departures are clearly understood and properly disclosed during placement.
Jones v Zurich Insurance Plc [2021] EWHC 1320 (Comm)
Jones v Zurich is a useful first-instance application of the materiality test in a more everyday context. The case concerned a travel insurance claim where the insurer relied on undisclosed prior medical history. While decided largely on consumer-style principles (under the Consumer Insurance (Disclosure and Representations) Act 2012), the judgment contains observations on the prudent insurer standard and on how courts approach the credibility of underwriter evidence on materiality and inducement that are useful by analogy in commercial cases. The court’s approach to testing underwriter witness evidence is a reminder that an underwriter’s bare assertion of materiality, unsupported by underwriting guides or contemporaneous records, may be given limited weight.
Yam Seng Pte Ltd v International Trade Corporation Ltd [2013] EWHC 111 (QB)
Yam Seng, decided by Leggatt J (as he then was), is not an insurance case. It is the modern English foundation for the implication of a duty of good faith in commercial contracts. Its relevance to the material circumstance test is contextual rather than direct: the Insurance Act 2015 retains the duty of good faith between insurer and insured (though without the avoidance remedy formerly attached to it), and the broader common-law trajectory recognised in Yam Seng — that long-term, relational commercial contracts can carry good-faith expectations including honesty and fair dealing — informs how the courts approach allegations of bad faith and reckless non-disclosure under the Act. For brokers, the practical point is that “I didn’t think the underwriter would care” is rarely a satisfactory answer to a materiality challenge in a relational commercial placement.
Common materiality flashpoints in commercial placements
Drawing the case law and our placement experience together, the following are the recurring materiality flashpoints. Each warrants specific attention at placement and renewal.
Previous insurer cancellation, refusal or special terms
Whether any insurer has previously declined, cancelled, refused renewal of, or imposed special terms upon, any cover for the insured or any director is almost universally material. Underwriters expect to see it disclosed and inducement is generally not difficult for an insurer to prove if it is not.
Director and senior manager regulatory matters
Following Berkshire Assets, any open or recent investigation by the FCA, SFO, ICO, HSE, HMRC, Companies House (in relation to director disqualification) or relevant professional body affecting senior management or controllers should be assessed for materiality. The starting point should be “likely material — consider how to disclose,” not “private matter.”
Pending or threatened litigation
Civil proceedings affecting the insured — whether as claimant or defendant — and credible threats of proceedings are routinely material to D&O, PI and commercial combined risks. The threshold is not “claim notified” but “circumstance that would influence the prudent underwriter.”
Moral hazard
Any matter going to the honesty, integrity or competence of those who own or run the insured is potentially material. This includes prior insolvencies, disqualifications, criminal convictions, and adverse regulatory findings against senior management.
Change in trade, process or technology
A material shift in what the insured does — new product lines, new geographies, adoption of new (and particularly automated or AI-enabled) processes — should be assessed for materiality at renewal. The “we are still a manufacturing business” answer is not enough where the manufacturing has materially changed.
Business continuity, cyber posture and supply chain
Particularly for cyber, business interruption and contingent BI placements, recent incidents, near-misses, ransomware demands (whether paid or not), and material changes to critical supply chain dependencies are likely material.
Acquisitions, disposals and group restructuring
Discussed in detail in our fair presentation article, but worth repeating: signed but unannounced deals, planned restructuring and material changes to group composition are routinely material to liability, financial lines and crime placements.
Testing materiality at placement: a broker’s approach
How should an insured (with broker support) actually test materiality on the ground? Our recommended discipline is:
- Start with the s.7(4)(c) test — would the market generally expect this topic to be addressed in this class of business? If yes, treat as material.
- Apply the “if a claim came in tomorrow” test — if the insured suffered a loss within 30 days and this matter then came to light, would the underwriter feel it had been ambushed? If yes, treat as material.
- Apply the “if in doubt, disclose” rule — it costs almost nothing to flag a borderline issue under s.3(4)(b) and it removes the issue from the insurer’s later toolkit.
- Document the call — a contemporaneous note explaining why an item was disclosed (or, more importantly, why it was not) is invaluable if the question is revisited two years later in litigation.
- Distinguish materiality from disclosure mechanics — a matter can be material and still be disclosed in summary form under s.3(4)(b) with appropriate signposting. The two questions should be answered separately.
What materiality is not
It is worth closing on what the test does not require:
- It is not a “but-for” test for the actual insurer. That is the separate inducement question and sits in Schedule 1.
- It is not a strict liability test. A circumstance that a reasonable search would not have revealed is not actionable, because the insured neither knew nor ought to have known it (ss.3(4), 4(6)).
- It is not a counsel of perfection. The Act expressly contemplates that summary disclosure plus signposting can satisfy the duty even where full chapter and verse is not provided.
- It is not an invitation to insurer over-reach. Underwriter assertions of materiality unsupported by underwriting guides, prior practice or contemporaneous records will be tested on their merits, as Jones v Zurich and the post-Act case law make clear.
Frequently asked questions
1. What makes a circumstance “material” under the Insurance Act 2015?
Section 7(3) provides that a circumstance is material if it would influence the judgement of a prudent insurer in determining whether to take the risk and, if so, on what terms. The test is objective and is satisfied even if the influence would not be decisive.
2. Does the insurer also need to show it was actually induced?
Yes. The Schedule 1 remedies regime requires the actual insurer to show that, but for the breach, it would not have entered into the contract or would have done so only on different terms. This carries forward the inducement requirement from Pan Atlantic v Pine Top [1995] 1 AC 501.
3. Are regulatory investigations against directors disclosable even if no charges have been brought?
Following Berkshire Assets v AXA [2021] EWHC 2689 (Comm), regulatory and criminal matters affecting controllers and senior management are routinely treated as material — including where charges are contested or extraterritorial. The safer course is to disclose, applying section 3(4)(b) signposting where appropriate to protect privilege.
4. Is a previous declinature or insurer cancellation material?
Almost invariably yes. Underwriters expect this to be disclosed across virtually all classes of commercial business, and inducement is typically straightforward for an insurer to evidence if such matters are omitted.
5. How does materiality interact with section 3(4)(b) “signposting”?
The two questions are separate. Section 7(3) determines whether a circumstance is material. Section 3(4)(b) provides that material circumstances can be disclosed by giving sufficient information to put a prudent insurer on notice that further enquiries are needed, rather than by full disclosure.
6. If our underwriter never asks about something, can we assume it is not material?
Not safely. Silence in a proposal form may amount to waiver in some circumstances, but the materiality test is grounded in what a prudent insurer would want to know, not what this particular underwriter happened to ask. The “if in doubt, disclose” rule applies.
7. Does the inducement requirement help insureds in practice?
It can. An insurer that alleges breach but cannot evidence — through underwriting guides, contemporaneous notes or credible witness evidence — that it would have acted differently faces a real problem on inducement. Insureds and brokers should test underwriter inducement assertions rigorously.
8. Where does Pan Atlantic v Pine Top fit into the post-Act regime?
Pan Atlantic remains authoritative on the “would influence” standard (now in s.7(3)) and on the inducement requirement (now built into Schedule 1). It is foundational reading for any post-Act materiality dispute.
