British green electricity supplier could be in hot water after a competitor commenced legal action over a possible breach of copyright.
Ecotricity, which develops wind farms and provides electricity to more than 40,000 UK homes claims that the Green Energy Day green Union flag is too similar to its own branding, which it has been using for two years.
A spokeswoman for Ecotricity said: “A lot of our customers have been contacting us, confused by the EDF branding.
“We know you cannot trademark a flag, but we feel that we have a good case because the colours are so similar.”
Ecotricity ran an ad using its own green flag to welcome the Prime Minister Gordon Brown to power in 2007.
