The move is part of a voluntary initiative by the Energy Saving Trust and Defra ahead of an expected surge in demand for new TVs before the World Cup.
Defra claims the least eco-friendly 42-inch televisions can cost around £75 a year to run, whereas the same sized energy-efficient TV would cost only £33.
Some 1.6 million sets are expected to be sold in the World Cup run-up. The participating retailers, including Best Buy UK, Comet, Currys and Argos, have a 50% share of the TV market.
"It's great for people to know the models sold by these retailers will save them money on energy bills and help the environment," said environment minister Dan Norris MP.
