The business has been sold to Socium Group, which is backed by Penta Capital.
This is the third exit that Lonsdale has announced this year and the second from its current fund, which closed in April 2016 at £110m.
CC&A has undergone rapid growth since Lonsdale acquired the business in January 2018, expanding its base of corporate partners and advisers and developing its digital and mobile capabilities.
As a result, annual revenue increased from £9m to £13m during Lonsdale’s ownership.
Founded in 2004, CC&A offers mortgage advice services to clients and partners with the Employee Benefits and HR teams of approximately 200 companies, to provide financial education and support employees’ financial wellbeing.
It now has more than 90 mortgage and protection advisers who are backed by a dedicated administration department, completing over 700 mortgages every month.
In the 122 months to April 2021, CC&A completed in excess of £3.1bn in mortgages for its clients.
David Gasparro, co-founder of Lonsdale Capital, said: “We have greatly enjoyed working with the team at CC&A and would like to take the opportunity to acknowledge the successful growth and expansion that they have achieved during our ownership.
“The development of strong digital credentials meant the business was able to enhance its service and respond to the growing demand for remote access, particularly in the wake of COVID-related social distancing.
“As a result, the business has substantially increased the number of clients and blue-chip partner organisations to whom it offers the highest levels of customer service and expert advice.
“We wish the team continued success within the Socium Group.
“2021 has been a strong year for Lonsdale, with three exits announced in the last seven months.
“We have six fast growing businesses in our current portfolio and expect to see continued strong momentum in the months ahead.”
Simon Nimmo, founder and chief executive of CC&A, said: “We always strive for customer service excellence, delivering quality mortgage education and advice from the most experienced and professional advisers in the industry.
“Recent years have brought financial challenges for many and we are proud of the enhanced service we have been able to provide to an increasing number of clients and partners.
“Lonsdale’s support has been instrumental to our expansion and we look forward to building on this under the Socium Group of companies.”
