Simply Switch, which sits in the Associated Northcliffe Digital division of Associated, has ambitions of increasing its brand awareness, and, according to sources, plans to spend up to £4 million a year on advertising.
The service, which launched in 2002, and is a rival to uSwitch.com in the online price-comparison market, was bought by Associated last August for £22 million.
Media planning and buying is currently handled by Coltman Media, and creative by Zinc Advertising.
Simply Switch hopes to benefit from an inflationary energy market, which saw four million people switch their gas or electricity supplier in 2006.
It also provides price comparison in the home phone, mobile, broadband and credit-card markets, and a service for consumers to switch accounts online or over the phone.
Simply Switch denied there was a pitch.
