Openwork has struck a deal with Newcastle Financial Services (NFS) to extend its network membership for a further five years.
NFS, a subsidiary of Newcastle Building Society is Openwork's largest adviser member and joined the network in 2003, when it was called Zurich Advice Network.
NFS has 22 pension and investment advisers and four insurance advisers.
Steve Urwin, sales and marketing executive at Newcastle Building Society, said: 'NBS recognises that other high street providers are withdrawing from offering advice to the mass market but we are committed to maintaining a service for our members.
'In our view Openwork has the most compelling and progressive proposition in the market and it is very well placed to support our evolving requirements both now and in the years ahead. We were more than happy to extend our relationship with the business for a further five years.'
Mark Duckworth, managing director of marketing and distribution at Openwork said: 'NFS has been with Openwork from the very beginning and we are extremely pleased the team is extending the relationship with us for a further five years.
'The business’s continued growth year-on-year is testament to the quality of service it provides to its clients, and its decision to commit its future to Openwork at such a pivotal time for the industry is a fantastic endorsement of our proposition and strategy.'
