Vodafone is moving an additional 300 people into its Wythenshawe contact centre, which is to become its main UK base for customer service.

Ninety existing roles at the telecoms giant will move to Berkshire as part of the major company shake-up which is looking to collect staff into ‘centres of excellence’.

The announcement comes as the group announced an €800 million drop in annual revenue to €11 billion.

In two years’ time the firm expects 1,400 people to be based at the North West contact centre while there will be specialist support at bases in Glasgow, Newark and Stoke.

The firm is developing digital and consumer services in London, while a digital technology centre will be created in Newbury.

"We are creating new centres of excellence in the UK, covering Customer Service, Consumer and Digital, and Technology,” a spokesman for Vodafone said.

"This is a major step to us becoming the UK’s leading digital technology and communications company and reinforces our commitment to the UK.

"From March this year, Manchester will be the centre of excellence for customer care with Glasgow, Newark and Stoke providing specialist support.

“Digital and consumer services will be developed in London, and Newbury will focus on innovation with the creation of one of the UK’s largest digital technology centres.

"Under this programme, we are uniting teams spread out over a number of smaller offices into larger centres.

"We recognise some employees will need to commute further or move, and we are speaking to them individually about their specific circumstances to provide support and help them stay with us. 

"We expect to have approximately the same number of employees following the two year-long exercise."
