Almost 200 jobs could go at a call centre in Norwich.
It comes as the Swinton Group announced plans to reshape its business model - putting more than 900 jobs at risk across the country.
The firm is investing £45m in enhanced IT and digital technology at its new head office and contact centre in Manchester.
The move means 84 branches are under review nationally as well as the call centre in Rosary Road, Norwich, which employs 183 people.
Swinton will now begin a formal consultation with all employees impacted by the proposals.
Where possible, affected staff will be deployed into other parts of the business.
