The margin applied to commercial property

Titan Europe 2006-3 plc v Colliers International UK plc [2015] EWCA Civ 1083 took the permissible margin of error into the commercial arena. The valuer had valued a large German logistics property at €135 million; the true value was found to be significantly lower. The property was unusual, purpose-built for a single tenant, and the market was difficult. The claim arose out of a securitised loan where the valuation had underpinned the lending.

The decision

The court confirmed that a valuation of an exceptional commercial property attracts a wider permissible bracket than a standard residential one, reflecting the genuine difficulty of valuing a specialised asset. On the facts, the valuation fell outside even the wider bracket and was negligent. The Court of Appeal upheld the finding, confirming both the approach to the margin and the way loss is measured on a negligent overvaluation.

Standing to sue

The case also addressed who could bring the claim in a securitisation, confirming that the issuer that held the loan and suffered the loss had standing. For a valuer, the practical point is that the eventual claimant in a structured finance transaction may be several steps removed from the party originally instructed.

Points for firms and their PI cover

Titan shows the margin of error operating at scale. Apex explains how limit adequacy and defence costs work for higher-value instructions on its surveyors' PI guide, and the parallel issues for cost and project consultants on the quantity surveyors' PI guide. For commercial valuation, the size of the potential loss makes limit selection a considered decision rather than a default.

Limit adequacy for commercial work

The scale of the loss in Titan, tens of millions of pounds, is the practical headline for any firm doing commercial valuation. A single instruction can generate an exposure many times the size of a typical residential claim, which makes the choice of limit a considered decision rather than a default. A firm valuing large or specialised assets should think about the largest realistic loss a single instruction could produce, not the average.

Aggregation is the other feature to understand. Where several valuations share an underlying cause, or where one transaction generates multiple related claims, the way the policy aggregates them determines how the limit and excess apply. In a securitisation the eventual claimant may be an issuer or assignee rather than the original client, which affects who gives notice and how the claim is defended. For commercial valuation practices, matching the limit and the aggregation wording to the true scale of the work is central to placing cover that would actually respond to a Titan-sized event.
