    No Hornets’ Nest Here: Lessons from Ahmed v White

    29/06/2026

    Ahmed v White & Co [2025] EWHC 2399 (Comm)

    Background

    Accounting practice White & Co, and its associated firm MKP, provided clients with financial and tax advice about investment in EIS and related schemes. The investments made losses. When White & Co and MKP went insolvent, individual investors claimed against their professional indemnity insurer, Allianz, under the Third Party (Rights against Insurers) Act 2010.

    Issues

    There were two key issues before the High Court:

    1. did White & Co notify Allianz of circumstances from which the later disputed claims arose; and
    2. did the policy’s Related Claims clause allow all relevant claims to be aggregated?

    Notification arguments

    The notification clause in the Allianz policy said:

    “The Policyholder shall as soon as reasonably practicable during the Policy Period notify the Insurer… of any circumstances of which any Insured becomes aware during the Policy Period which is reasonably expected to give rise to a Claim”.

    There were three relevant notifications to Allianz:

    1. The Akbar Letters – eight individual investors instructed a barrister who sent these letters on their behalf;
    2. The Block Notification – White & Co wrote to their broker when HMRC investigated the EIS investment schemes, saying “the cases under investigation are those where [MKP] advised. Cases involving advice provided by [White & Co] may be investigated in due course”; and
    3. The Kennedys Documents – White & Co and Allianz instructed Kennedys solicitors under a joint retainer to defend the claims referenced in the Akbar Letters. The ‘Kennedys Documents’ were party/party correspondence between the Akbar Letters barrister and Kennedys, which Kennedys shared with Allianz.

    The claimants argued that a reasonable person, with the background knowledge reasonably available to Allianz, would have understood these notifications collectively as a ‘hornets’ nest’ notification that White & Co would face other allegations of negligent tax and investment advice already made, meaning that no further notifications of subsequent similar claims were required.

    Allianz countered that (a) the Akbar Letters notified the Akbar Letters claims by the eight investors, but not other claims by other investors and (b) neither the Block Notification nor the Kennedys Documents amounted to a notification of circumstances or claims within the meaning of the policy.

    Notification findings

    Akbar Letters

    The court found nothing from the words used in the Akbar Letters would make the reader think other claims from claimants might arise. On its face the notification simply says the eight claimants in question intended to claim against White & Co for negligent advice.  

    The Block Notification

    The court found that the Block Notification was a valid notification of circumstances under the policy. The policy required White & Co to notify Allianz “as soon as reasonably practicable during the Policy Period… of any circumstance… which is reasonably expected to give rise to a Claim”. The notification was, however, confined to allegations against MKP. It did not put Allianz on notice of claims against White & Co. Whilst a reasonable person in White & Co’s position would have understood that it might face future claims, White & Co did not communicate this to Allianz.

    The Kennedys Documents

    These documents did not comprise a valid notification to Allianz. Kennedys was not White & Co’s agent for the purposes of notifying circumstances to Allianz and, indeed, if it had been, then that would have created a conflict of interest under the joint retainer.

    Conclusion

    The court found there was no ‘hornet’s nest’ notification.

    Aggregation

    The Policy defined “Related Claims” as:

    “any Claims alleging, arising out of, based upon or attributable to the same facts or alleged facts, or circumstances or the same Wrongful Act, or a continuous repeated or related Wrongful Act”.

    The claimants argued that this did not apply to the various investment claims: (1) the claims did not arise from the “same” facts or alleged facts because White & Co advised each claimant separately; (2) each claimant suffered their own loss; and (3) each instance of negligent advice was a separate breach of duty to a separate claimant.

    In contrast, Allianz argued these were all “Related Claims” because White & Co’s alleged “Wrongful Act” was the same for each claimant.   

    On the first of the claimants’ arguments, the court held that there is nothing in the language of the Related Claims provision which prevents a claim whether actually notified or one that arises from a communication, that falls within the deeming provision of the policy relating to the notification of circumstances from also falling within the category of “Related Claims”.

    The court held that the adjective “same” (which qualified “facts”, “alleged facts” or “circumstances) significantly modified the Related Claims clause. Mere similarity was not enough: it had to be the “same”.  In this case, however:

    1. Each claimant received their own advice;
    2. Each claimant entered into their own investments;
    3. Each claimant suffered their own loss;
    4. There was no connection or interdependency between each claimant’s investments; and
    5. White & Co’s negligence regarding one claimant did not cause its negligence regarding any other claimant.

    The court therefore held that each act of negligence was a separate breach of duty to a separate claimant. Those negligent acts did not collectively constitute the “same” Wrongful Act.

    However, the Related Claims clause went on to refer to a “related Wrongful Act”. The court found this was effective to aggregate the claims as “Related Claims”: White & Co’s allegedly negligent investment advice for the EIS, Seed EIS and Super EIS investments was all based on its understanding of section 165 of the Income Tax Act 2007.

    Comment

    This case is a reminder that the precise wording of a notification matters, especially for those wanting to make a ‘block’ or ‘hornet’s nest’ notification. It is also helpful confirmation that jointly instructed solicitors do not typically act as the policyholder’s agent for the purpose of notifying insurers. 

    Furthermore, as usual, aggregation comes down to a forensic examination of the wording and the facts: here the single word “related” proved to be determinative against the factual matrix.
