Dyson asks European court to scrap EU energy labelling law

Dyson argues tests don't reflect real-world energy use but green campaigners say they have still made vacuum cleaners more efficient and help cut energy bills

The British technology firm Dyson is asking the European court to throw out a large chunk of the EU's energy efficiency legislation following accusations that rival firms are misleading customers over the way their products operate.

Dyson, headed by the British engineer James Dyson, is seeking to quash the EU's regulation for vacuum cleaners at the European court of justice.
