The network said the rise has come despite a long-term decline in the number of advisers working in the UK market.

The 3,000 advisers work within its core network, its protection business Owl and its nationwide IFA firm 2plan wealth management.

CEO Mark Duckworth said: “Exceeding 3,000 advisers for the first time in Openwork’s history is a huge achievement for the business, particularly in light of the long-term fall in adviser numbers in the UK.

“Our growth, however, has not come at the expense of quality and it is extremely pleasing that Openwork continues to attract high-calibre advisers; something that speaks to the significant appeal of our proposition but also our unique structure, which gives firms joining us part-ownership of the business and influence over its direction.”

In February, Openwork announced it had signed an agreement that will see Zurich divest its 25 per cent shareholding in the network within four years. By March 2020, Zurich will transfer its shares to Openwork’s other main shareholder, Openwork Partnership LLP, which represents the adviser base.

The business also reported it had raised more than £2.5bn into its fund range Omnis, less than 30 months since launch.
