Class Action Lawsuit | Europe | Society

Introduction: No Energy left in Lawsuit

Millions of UK electricity customers have suffered a legal setback in their bid to recover losses from alleged cartel conduct by high-voltage power cable manufacturers. A proposed class action brought under the umbrella of competition law has stumbled at a critical juncture.

Background

In 2014, the European Commission found that several high-voltage and submarine power cable manufacturers — including Prysmian Group (Italy), Nexans SA (France) and NKT A/S (Denmark) — had operated a cartel between 1999 and 2009, allocating customers and territory and fixing bids in the European market for cables.

The claim asserted that UK energy network operators paid inflated prices for these cables, and that those extra costs were ultimately passed on (via regulated price controls) to domestic electricity consumers in Great Britain.

The UK Proceeding

Under the UK collective proceedings regime, the Competition Appeal Tribunal (“CAT”) certified a proposed collective action led by Clare Spottiswoode (a former regulator) on behalf of more than 30 million domestic electricity consumers. The claim sought hundreds of millions of pounds in compensation for the alleged pass-on of cable overcharges. (Top Class Actions United Kingdom)

The claim, however, ran into significant obstacles. For example, in an earlier “follow-on” case brought by the joint UK-Netherlands grid operator BritNed against ABB Group, the High Court found only limited overcharge, rejecting large elements of the claimant’s asserted economic model.

Why the Consumers “Lost”

Although the 2024 court certification process allowed the case to proceed, key legal and evidentiary hurdles mean that many consumers may not recover compensation:

• Establishing pass-on: It must be shown that the inflated cable prices were passed directly to the final consumer, rather than absorbed elsewhere within the supply chain or regulated differently.
• Quantifying loss: Identifying how much of each consumer’s bill was inflated by the cartel conduct presents significant economic modelling challenges.
• Causation & timing: The cartel operated between 1999 and 2009; many customers must show that they paid higher electricity bills as a direct consequence over many years.
• Collective action viability: Even if certified, collective proceedings under UK law require appropriate funding, management of opt-out rights, and a clear damages allocation mechanism — all of which add cost and delay.

Because of these combined obstacles, while the claim is still alive, the practical prospect of many individual customers recovering substantial amounts appears limited — hence the characterization that “millions of UK grid customers lost the lawsuit”. In effect, the claim may not deliver meaningful redress for most end-users.

Legal and Regulatory Significance

The case highlights several broader lessons:

• The challenge of follow-on claims in competition law: even when liability is established (as via the EC cartel decision), converting that into meaningful damages for mass-market consumers remains difficult.
• The importance of economic evidence: Courts are increasingly sceptical of inflated models that assume full pass-on or high overcharges without robust support (see the BritNed/ABB case).
• Collective proceedings mechanism tested: The UK’s relatively new collective action regime for competition law is still evolving, and this cable-cartel case is among the early high-profile tests.
• Consumer harm as a downstream effect: The case underscores how upstream cartel behaviour (in cable supply) can link, at least theoretically, to downstream consumer bills — but proving that link is complex.

What Next?

Although many claimants may not recover, the litigation is not definitively over. The certification to proceed means that trial or settlement remains possible. Claimants’ law firms may seek to refine damage models, negotiate for settlements or pursue narrower sub-classes of claimants who can better establish loss. Meanwhile, the defendant cable manufacturers continue to contest the scope of pass-on and the quantification of damages.

Conclusion

This contested case reveals a stark reality: even when anticompetitive conduct is proven at the regulator level, achieving effective compensation for everyday consumers remains an uphill battle. For millions of UK electricity users, the promise of redress for inflated bills appears remote. The legal system may have recognised the possibility of harm — but translating that into real-world recovery for households is another matter entirely.
