Sue Davies, Which? Head of Consumer Protection Policy, said:
“We know that consumers want to make more sustainable choices so it’s good that the government is investigating concerns that some suppliers appear to be ‘greenwashing’ their energy tariffs, which could risk misleading customers.
“We believe there needs to be greater clarity on how renewable electricity is defined and marketed. If the government concludes that firms are not being upfront and transparent about their green credentials, it should take action to ensure people can make informed decisions about where to buy their energy from.”
