Professional liability: Breach and factual causation are not enough

15 October 2026
A professional negligence claim against solicitors failed despite findings of breach of duty and factual causation. The High Court held that the claimant's loss fell outside the scope of the duty breached, providing a practical illustration of the scope of duty analysis.
The recent decision in Niprose Investments Ltd v Vincents Solicitors Ltd [2026] EWHC 2320 (Ch) provides a useful illustration of how courts continue to apply the scope of duty principles developed in Manchester Building Society v Grant Thornton and Meadows v Khan.

The case also contains helpful observations on the effect of the SRA Warning Notice relating to investment schemes and off-plan developments, and on the relevance of client sophistication when assessing the content and extent of a solicitor's advisory obligations.

Background

Niprose Investments Ltd (‘Niprose’) was a family investment company established to acquire eight units in an off-plan residential development known as “The Rise” in Liverpool. Under the funding model, purchasers were required to pay deposits amounting to 50% of the purchase price on exchange of contracts.

Niprose paid deposits totalling approximately £299,800. The development subsequently failed following funding difficulties and the insolvency of the development entities. Having lost its deposits, Niprose brought a professional negligence claim against its conveyancing solicitors, Vincents Solicitors Ltd (‘Vincents’).

Niprose alleged that Vincents had failed to advise that the deposits had no meaningful security or protection, failed to advise against proceeding with the transaction, and failed to ensure that the risks were properly understood.

An important issue concerned the experience and sophistication of Mrs Nickoll, the directing mind of Niprose. The judge found that she was highly intelligent, commercially astute and well able to understand complex documentation and commercial risk. She had carefully reviewed the transaction documents, undertaken substantial due diligence and read the SRA Warning Notice supplied by Vincents.

Breach of duty

Was there a duty to advise Niprose not to proceed?

Niprose argued that Vincents should have advised against proceeding with the transaction altogether. This was described as a “bargepole duty”, reflecting the contention that the risks were such that a reasonably competent solicitor should have warned the client away from the investment.

The argument relied heavily upon the SRA Warning Notice relating to investment schemes and off-plan developments.

The court rejected this part of the claim. HHJ Hodge KC held that the Warning Notice did not create new legal duties. Rather, it reflected existing professional obligations and emphasised the need to explain unusual risks. It did not, however, impose a general obligation upon conveyancing solicitors to advise clients against entering into transactions simply because they involved significant commercial risk.

The judge found that the development was a genuine investment opportunity, rather than a sham or fraudulent scheme. There was nothing known, or reasonably discoverable, by Vincents to suggest that the project was bound to fail or that Niprose was proposing to enter into a manifestly reckless venture.

The court therefore concluded that this was not one of the exceptional cases in which a solicitor was required to advise the client not to proceed. As the judge observed, solicitors are not “nursemaids” or “gatekeepers on commercial activity”.


Did Vincents have to ensure that Niprose understood its advice?

Niprose also argued that Vincents was under a heightened obligation to ensure that it had actually understood the advice provided.

The report on title had repeatedly warned of the risks associated with an off-plan development, including the possibility that the developer might fail and that the deposits could be lost. Niprose had also signed a confirmation that it had read and understood the advice.

Taken together with the court’s findings regarding Mrs Nickoll’s experience and commercial sophistication, this was sufficient to defeat the broader allegation that Vincents had failed to ensure that the risks were understood.

Niprose did, however, succeed on one aspect of its case. The court found that Vincents had failed adequately to explain the effect of Schedule 2 to the sale agreement and, in particular, the mechanism governing the release of the purchasers’ deposits.

The protection afforded by the contractual arrangements was materially more limited than Niprose had understood. The report on title did not explain that distinction with sufficient clarity. That failure amounted to a breach of duty.

Causation and scope of duty

The court accepted that Mrs Nickoll had not appreciated the true limitations of the deposit release mechanism. It also accepted that, had Niprose had been properly advised about the practical absence of meaningful protection for its deposits, it would probably have withdrawn from the purchases and sought the return of its reservation fees.

Niprose therefore established factual causation. In other words, it showed that, but for the breach, it would not have entered into the transactions and would not have suffered the loss. That was not, however, the end of the matter.

The court was also required to identify the purpose of the duty breached and to decide whether the loss represented the materialisation of the risk against which that duty was intended to protect. This was the separate scope of duty, or “duty nexus”, analysis considered by the Supreme Court in Manchester Building Society v Grant Thornton and Meadows v Khan.

The breach concerned the deposit release mechanism and the limited protection provided by Schedule 2. The loss, however, arose because the developer became insolvent and the development failed.

There was no evidence that the deposits had been misappropriated or released otherwise than in accordance with the contractual arrangements. Nor was there evidence that shortcomings in the Schedule 2 mechanism had caused or contributed to the collapse of the development or the insolvency of the development entities.

The court therefore treated the inadequacy of the deposit release mechanism and the failure of the development as different distinct risks. The deposits were lost because the development failed, not because the release provisions operated in the particular manner that Vincents had failed adequately to explain.

Applying the scope of duty analysis, and cross-checking the outcome by reference to the counterfactual approach associated with SAAMCO, the court concluded that Niprose’s loss did not fall within the scope of the duty which Vincents had breached.

The claim was therefore dismissed, notwithstanding the court’s findings that Vincents was in breach of duty and that the breach was a factual cause of the loss.

Practical implications

The principal significance of the decision lies in its clear distinction between factual causation and the scope of a professional adviser’s duty.

A claimant cannot necessarily recover all losses arising from a transaction simply because it can show that, but for the defendant’s negligence, it would not have proceeded. The court must still identify the purpose of the advice which should have been given and consider whether the loss arose from the very risk which that advice was intended to guard against.

The decision may be particularly relevant to claims arising from failed property developments and other investments. In such cases, a claimant may allege that deficient advice about one feature of the transaction caused it to enter into the investment. However, if the eventual loss arose from insolvency, adverse market conditions or wider commercial failure, a separate question remains: does that loss falls within the scope of the particular duty breached.

The court’s treatment of the SRA Warning Notice is also important. Regulatory guidance may assist in identifying the standards expected of a solicitor, but it does not necessarily create a separate common law duty. In this case, the Warning Notice reinforced the need to explain unusual risks, but it did not require solicitors to advise against every transaction involving significant commercial risk.

The findings concerning Mrs Nickoll also demonstrate that the content and extent of a solicitor’s duty will depend upon the circumstances of the particular retainer. A client’s experience, commercial sophistication and conduct may all be relevant when assessing both the adequacy of the advice given and whether further steps were required to ensure that the advice was understood.

The judgment also highlights the importance of contemporaneous documents in defending professional negligence claims. Vincents’ report on title, email correspondence and provision of the SRA Warning Notice were important in rebutting several of the wider allegations against the firm. They also provided the an objective evidential record against which the court could assess the witnesses’ retrospective accounts.

Whether Niprose becomes a frequently cited authority remains to be seen. However, it provides a clear and practical example of a claim in which breach of duty and factual causation were established, but the claim still failed because the loss fell outside the scope of the defendant’s duty.
