Car manufacturers will face heavy fines if they supply vehicles designed to cheat emissions tests to the UK, the government has confirmed.

Under new regulations, manufacturers face a potential penalty of £50,000 for each new vehicle found to be fitted with a so-called ‘defeat device’.

The rules have been confirmed in the government response to feedback on its consultation document, Road Vehicles: Improving air quality which the NFDA had responded to. Respondents to the consultation, said the Department for Transport (DfT), gave “overwhelming support for measures to crack down on emissions cheats”, according to Air Quality News.

Transport Minister Jesse Norman said: “There has rightly been a huge public outcry against car manufacturers that have been cheating on emissions standards. Their behaviour has been dishonest and deplorable.

“These tough new regulations are designed to ensure that those who cheat will be held to proper account in this country, legally and financially, for their actions.

“The Road Vehicles (Defeat Device, Fuel Consumption and Type Approval) Regulations 2018 will be laid in Parliament before coming into force on 1 July 2018.”


As Air Quality News reports, DfT acknowledged that respondents commented that “Generally the manufacturer was seen as primarily responsible for the defeat device, an importer would be less likely to know about the device and a dealer even less likely to know about it. The latter two parties were also seen to be unlikely to have the technical capability to find such a device and respondents felt that it would be unreasonably onerous and costly to ask them to check for one as a matter of course.”

Key points

The announcement included plans to:

  • introduce additional offences and penalties for manufacturers who fit defeat devices to road vehicles, motorcycles and agricultural tractors
  • require manufacturers to publish fuel economy figures obtained from the new Worldwide [harmonised] Light vehicle Test Procedure (WLTP) laboratory test from 1 January 2019
  • update a number of safety and environmental requirements for vehicles approved under National Small Series Type Approval (NSSTA) and Individual Vehicle Approval (IVA)
  • introduce strict limits on derogations for light duty vehicles not tested under the new WLTP
