Non-disclosure is failing to disclose information that is material to the insurer’s decision to take on the risk. Misrepresentation is providing information that is materially inaccurate. Both can lead to remedies under the Insurance Act 2015, but they are conceptually distinct breaches of the insured’s duty of fair presentation.
Both concepts sit inside the duty of fair presentation imposed on commercial policyholders by section 3 of the Insurance Act 2015. The duty requires the insured to disclose every material circumstance the insured knows or ought to know, or to make disclosure sufficient to put a prudent insurer on notice that it needs to make further enquiries.
Non-disclosure is the failure to disclose a material circumstance that the insured knew or ought to have known. The insured remained silent on something it should have raised.
Misrepresentation is a statement, in answer to a question or in a presentation document, that is materially inaccurate. The insured spoke but spoke incorrectly.
The distinction matters because the factual investigation and evidential proof differ. Non-disclosure looks at what the insured knew but did not say; misrepresentation looks at what the insured said and whether it was right. The remedies under the Insurance Act 2015 are largely the same, but the path of analysis is different.
The Act overhauled the previous common-law and Marine Insurance Act 1906 regime. Three features matter.
Duty of fair presentation. Replaces the older duty of “utmost good faith” disclosure for commercial insureds. The new duty requires either (a) full disclosure of every material circumstance known or constructively known, or (b) disclosure sufficient to put a prudent insurer on notice that further enquiry is needed. Either approach satisfies the duty. See PI utmost good faith for the older concept.
Materiality and inducement. A circumstance is material if it would influence the judgement of a prudent insurer. A misrepresentation has remedy consequences only if the insurer was induced — i.e. would have acted differently had it known the true position.
Proportionate remedies. The Act introduced proportionate remedies depending on whether the breach was deliberate or reckless, or merely careless. Deliberate or reckless breach allows the insurer to avoid the policy and retain the premium. Careless breach permits proportionate adjustment — the insurer may apply the terms it would have applied had it known the true position (higher premium, additional exclusions, additional warranties), or, where the insurer would not have written the risk at all, avoid the policy with refund of premium.
The distinction between non-disclosure and misrepresentation does not change the remedy regime, but it can affect the factual conclusion. A failure to mention a known issue may more readily be characterised as deliberate than an answer that turns out to be incorrect due to a misunderstanding.
A medium-sized accountancy firm completes a proposal at renewal. Three matters arise.
Matter A: The proposal asks for fee income by service line. The firm gives accurate figures for audit and tax but omits a small advisory fee stream of £180,000 a year. The omission is non-disclosure of the advisory income.
Matter B: The proposal asks “have you had any claims or circumstances notified in the last five years?” The firm answers “no”, forgetting a small notified circumstance from three years earlier that closed without a payment. This is a misrepresentation in the answer.
Matter C: The proposal asks about anti-money-laundering procedures. The firm describes its procedures correctly but does not mention a regulator visit two months earlier that flagged concerns. Whether this is non-disclosure or misrepresentation depends on whether the description of procedures was rendered inaccurate by the visit — which is a fine line.
Under the Insurance Act analysis:
The outcome under the Act is calibrated to the facts and is far less binary than the pre-2015 position, which could result in complete avoidance for any material breach regardless of fault.
Three contexts make the non-disclosure / misrepresentation distinction practically important.
Defending a coverage challenge at notification. When an insurer raises a coverage issue based on proposal-stage breach, characterising the matter as non-disclosure or misrepresentation drives the investigation: what was known, what was asked, what was answered. Defence counsel will analyse each contested point.
Renewal questionnaire design. Insurers structure renewal questionnaires to convert what might be non-disclosure (silence) into misrepresentation (specific answers). A specific question — “have you reviewed your books and records for any matter in the last 12 months that might become a claim?” — converts the duty to volunteer information into the duty to answer accurately.
Senior management responsibility. The Act attributes to the insured the knowledge of senior management and those responsible for arranging the insurance. Who in the firm knew what becomes a central inquiry, particularly when there is later dispute over whether something was “known”.
The legal landscape around fair presentation has several variants:
What is the difference between non-disclosure and misrepresentation?
Non-disclosure is failing to volunteer material information you knew or should have known. Misrepresentation is giving an answer that is materially inaccurate. The first is silence; the second is incorrect speech.
Which is more serious?
Neither is inherently more serious. Both are breaches of the duty of fair presentation under the Insurance Act 2015. The remedy depends on whether the breach was deliberate, reckless or careless, not on which kind of breach.
Can the insurer void my policy for innocent mistakes?
For careless breaches, the insurer applies proportionate remedies — typically adjusting cover to what it would have written had it known the truth. Complete avoidance is generally reserved for deliberate or reckless breach, or for cases where the insurer would not have written the risk at all.
What is fair presentation?
The Insurance Act 2015 duty to disclose all material circumstances or to disclose enough to put a prudent insurer on notice that further enquiry is needed. Fair presentation is the modern UK commercial insurance disclosure standard.
Whose knowledge counts?
The insured’s. Section 4 attributes the knowledge of senior management and the persons responsible for the insurance. The insured is expected to make a reasonable search of information available within the organisation.
Does answering specific questions release me from the duty to disclose other things?
No. Specific questions narrow the focus but do not exhaust the duty. Material information outside the questions still needs to be presented, by direct disclosure or by signposting that further enquiry would be useful.
Can the insurer add an exclusion mid-term for non-disclosure?
If a careless breach is discovered mid-term, the insurer may, depending on what it would have done at inception, apply the wording adjustments retrospectively. The policy may end up with different terms than originally agreed.
What is signposting?
A way of meeting the duty without disclosing every detail: alerting the insurer to an area where it should ask further questions. The Act expressly permits signposting and recognises that complete information is not always practical.
