The deal, worth an estimated £3.5 billion, will mean the creation of a 50/50 owned entity which will be renamed Dixons Carphone.
Dixons has over 500 PC World and Currys stories in the British Isles, while Carphone Warehouse own over 2,000 stories across Europe.
Dixons said there would be some minor job cuts after the merger but Carphone Warehouse said there will be more jobs available.
Paul Heywood, director of Dyn in Europe thinks that customers are going to demand a good experience as a result of the merger. But he warned that the shops will have to work together fast to exploit the market, reduce costs and provide good customer support.
