Three is no longer taking on new business customers as it looks to intensify its focus on the consumer market.
Mobile understands 14 jobs in Three's business team are under threat, with staff currently engaged in a consultation process with management.
The company will continue to serve small office and home office (SOHO) customers with no more than than four connections and honour its current contracts but will no longer actively market to other potential business customers.
Three's b2b customer base is small, consisting of around 0.5% of its customer base. Three business dealers were told this week to cease Three business channel trading as the operator terminated its b2b stockist codes with immediate effect.
Dealers were warned that all customer information is the property of Three and must not be used for promotional or sales purposes. Three dealers have also been warned that all offers such as cashback must be honoured.
A Three spokesman said: 'As the fastest growing operator in the UK we have chosen a clear focus and that is the consumer market.
'While we will continue to serve our existing business customers and small office/home office customers, we will no longer actively market to larger businesses.
'Our wholesale operation is developing well and through its growing roster of partners provides a range of options for business users looking to benefit from Three’s award-winning network.'
