Which? responds to the news that Vodafone and Three have agreed a UK merger

Rocio Concha, Which? Director of Policy and Advocacy, said: 

"A good mobile connection is essential to everyday modern life and this merger between Vodafone and Three will have a significant impact on the telecoms market. 

"There are currently four mobile network operators in the UK - EE, O2, Three and Vodafone - which smaller mobile providers then piggyback off. Reducing the number of network providers from four to three risks reducing the choices available to consumers, raising prices and lowering the quality of services available. 

"The CMA needs to conduct a thorough assessment to determine whether this merger will be harmful to consumers."
