GB Gas Holdings Ltd v Accenture (UK) Ltd & Ors

A contractual “Fundamental Defect” may arise from several breaches falling within the same warranty, and their consequences may be aggregated when assessing severe adverse effect. The effect need not have been fully suffered when notice is given if it would occur if the breach remained unremedied.

A notice need identify a Fundamental Defect and provide such analysis and detail as is reasonably practicable; it need not specify each breached warranty, contractual requirement, error or resulting effect. The notice is construed against its relevant background. Failure to take the prescribed contractual steps leaves the ordinary common-law damages claim intact. Losses naturally arising from the breach are not excluded merely because they relate to revenue, customer compensation or business financing.

Centrica brought preliminary issues arising from its claims that Accenture had breached warranties concerning an automated billing system supplied under the JPA, as amended. The principal questions concerned the meaning and operation of the contractual provisions governing “Fundamental Defects”, notification, Accenture’s remedial obligations, damages and the exclusion of indirect or consequential loss.

The court was asked to determine whether breaches and their consequences could be aggregated, whether a severe adverse effect had to precede notification, what information a valid notice had to contain, whether damages were limited by the remedial clause, and whether specified categories of loss were excluded by the contractual liability provisions.

1. Fundamental Defects. A fundamental breach of warranty could be constituted by individual breaches all falling within the same subparagraph of clause 15.2.1 or 15.2.2. The consequences of individual fundamental breaches could be aggregated when determining whether there was a severe adverse effect on the British Gas Business. The categories of Material Defect and Fundamental Defect were not mutually exclusive.
2. Timing of effect. A breach could constitute a Fundamental Defect where, at notification, it would cause a severe adverse effect if left unremedied. Accenture therefore could not avoid its obligations merely because the full effect had not yet been suffered.
3. Notification. Clause 15.4.3 was construed contra proferentem. A valid notice required a written statement that there was a Fundamental Defect and such analysis and detail as was reasonably practicable concerning the reasons for that belief. It did not require identification of each warranty, Statement of Release Requirements, error or severe adverse effect. The notice could be construed in the light of the parties’ prior knowledge and dealings.
4. Damages. Accenture’s warranty obligations and common-law damages liability were not merged in the prescribed-steps obligation. If Accenture failed promptly to take the required steps, Centrica could claim damages at large at common law for fundamental breach. Pre-notification losses were not excluded, and recovery was not limited to losses after a reasonable compliance period or to a Time and Materials calculation. The agreed liability cap remained applicable.
5. Excluded loss. The specified losses, including excess gas distribution charges, customer compensation, additional borrowing charges, debt-chasing costs and correspondence costs, were not excluded by clause 16.2 on the pleaded assumptions. They fell within the first limb of Hadley v Baxendale. Sums spent mitigating loss that was indirect or consequential would themselves have been irrecoverable, although that issue did not arise on the findings.
