A TV ad created by Kindred and called "power to switch", tells viewers that the government has made it easier to switch and they could save £200 on average.
It shows people at night with the amount of money they have saved illustrated in lights, and also features a series of photographs.
Art direction was handled by John Merriman and Vince Chasteauneuf. The copywriter was Gary Knight, while Merriman also took charge of creative direction.
It was directed by Noah Harris through Blinkink, with still photography by Dean Northcott. The media agency is Carat.
The campaign launches tomorrow and runs until late March.
Andy Ravan, the managing partner at Kindred, said: "The campaign highlights that millions have switched and saved big money in the process. The power to switch dramatises these benefits in a simple, clear and engaging way.
"DECC explained that they wanted something which would make the reforms they have made to the energy market real for domestic energy consumers.
"Essentially they wanted to get across that it’s now quicker and easier to switch, thanks to a more competitive market, which is benefiting consumers."
