Around 100 jobs will be impacted by the closure of telesales at energy giant SSE.

The company said it intends to redeploy 70 employees in Thatcham, Berkshire, and around 30 back office staff members in St Mellons, Cardiff, to other jobs in the company “wherever possible”.

SSE – one of Britain’s ‘’big six’’ energy suppliers – said it is ending the practice of cold calling potential customers, but will still call current customers and people who have agreed to be contacted.

The company’s energy supply brands – Southern Electric, Scottish Hydro and SWALEC – will only contact customers they already have a relationship with or potential customers who have previously agreed to a call, SSE said.

A small team will be established to deal with inbound calls from potential customers but they will not make unsolicited outbound calls, the company said.

SSE intends to redeploy the employees whose jobs are impacted “within customer service or other areas of the company wherever possible”.

In April, SSE customers were urged to seek compensation from the company after Ofgem announced it was to be fined a record £10.5 million for ‘’prolonged and extensive’’ mis-selling.
