Insurance Act 2015 section 7: what counts as a material circumstance

Defining materiality

Sections 3, 4 and 5 use the word material repeatedly. Section 7 of the Insurance Act 2015 supplies the definition and some supplementary rules that make the duty of fair presentation workable in practice.

The influence test

Section 7(3) states that a circumstance or representation is material if it would influence the judgement of a prudent insurer in deciding whether to take the risk and, if so, on what terms. The test is not whether the fact would change the outcome, but whether a prudent insurer would want it in the balance when setting terms or premium. This is a lower threshold than decisiveness, so firms should err towards disclosure where a point is arguable.

Examples the Act gives

Section 7(4) offers a non-exhaustive list of things that may be material circumstances: special or unusual facts relating to the risk, particular concerns that led the insured to seek cover, and anything that those concerned with the class of insurance would generally understand should be dealt with in a fair presentation. For a professional firm this readily captures a known dispute, an unusual instruction outside the firm's ordinary work, or a concentration of fee income in a single high-risk client.

What is not material

Section 7(5) confirms that, absent enquiry, a firm need not disclose circumstances that diminish the risk, that the insurer knows or is presumed to know under section 5, or that the insurer waives. Waiver commonly arises where a proposal form asks a limited question and thereby signals the insurer is not interested in the wider area.

Applying it to professional firms

A management consultant taking on a first engagement in a regulated sector, or a solicitor moving into a new area of practice, is dealing with the kind of unusual fact section 7(4) has in mind. The management consultants' PI guide and the solicitors' PI guide set out how work-type disclosure feeds the underwriting picture. Apex helps clients identify which features of their practice cross the materiality line.

The consequence of getting it wrong

If a material circumstance is not fairly presented, and the breach is a qualifying one under section 8, the insurer gains a remedy. Section 7 is therefore the gateway between the duty and its consequences.

Habits that keep presentations fair

Materiality is judged from the insurer's perspective, which can be hard for a firm to gauge in the abstract. Two habits help. First, when a fact would make the firm hesitate if it were the underwriter, disclose it. Second, keep a running note through the year of anything unusual, a large one-off instruction, a change of practice area, a client complaint, so that at renewal the material circumstances are already gathered rather than reconstructed from memory. The influence test in section 7(3) rewards firms that surface such matters rather than leaving the underwriter to discover them after a claim.
