British vacuum manufacturer Dyson is challenging new EU’s labelling laws concerning vacuum cleaners, claiming that the tests used do not reflect how the products are used at home.

From September next year, all vacuum cleaners sold in the EU will be required to carry a rating equating to their performance and energy efficiency. However, Dyson has claimed that "The regulations stipulate that vacuums should be tested in laboratory conditions: empty and with no dust. This does not simulate real-life conditions and is not representative of the view of testing and standards bodies across Europe."

It added: "Dyson fully supports the ambition to make the environmental impact of a machine easier to understand," said a spokesman for the firm.

"However, we are challenging aspects of the label because it will mislead consumers - notably the fact that the machines are tested in lab conditions free of dust, and the fact that environmentally damaging and costly consumables are not considered."
