The independent financial advisory firm has also appointed Sarah Covey as chief operating officer, it said in a statement today (May 10).
Loughridge was previously a director of 1825 Financial Planning, and before that spent 18 years at Grant Thornton, most recently as a partner in the wealth advisory team.
His appointment is subject to regulatory approval.
Piwa is part of the Sandringham Financial Partners Network, which currently has 190 IFAs advising on £3bn in assets.
It was launched by Messenger, formerly advice director at Abrdn, earlier this year, who is on the hunt for advisers to join the business.
Sandringham is part of M&G Wealth.
Loughridge said: “I look forward to working alongside Neil and Sarah to build on the firm's strong foundations and deliver outstanding results for our clients, with the added benefit of leveraging Sandringham’s tried and tested capabilities to enable us to scale at pace.”
Covey, who left her previous role to focus on finishing her second book, said: “Having worked with Neil for over a decade, I quickly saw what a compelling proposition this is.
“Sandringham’s support allows advisers to focus on clients. I look forward to contributing my expertise to help drive the company's continued success.”
