Affinia, an Essex-headquartered accountancy and advisory group, has expanded its presence in Surrey with the acquisition of PK Group, a firm providing accountancy, tax advisory and payroll services with offices in Richmond and Woking. The merger increases the group’s workforce to more than 600 staff and brings its total office footprint to 12 across London, East Anglia and South East England.
Patrick Kennedy, founder and chief executive of PK Group, said the decision to join Affinia followed careful consideration of partners that aligned culturally and could complement the firm’s approach. He added: “Affinia shares our high standards and commitment to excellence, and I am confident this partnership will allow us to invest in and grow our business while ensuring our valued clients remain well-supported in the years ahead.”
The acquisition is one of several undertaken by Affinia in 2025. Earlier this year, the group welcomed Opass Billings Wilson & Honey in Sidcup, Kent, and Clarkson Hyde in Sutton, further extending its reach across the South East.
Rob Harden, chief development officer at Affinia, described the integration of PK Group as a positive step for the company. He said: “We are delighted that PK Group has become part of the Affinia family. With a shared ethos of putting clients first and going the extra mile, the combination with PK Group further strengthens Affinia’s commitment to providing exceptional services and broad advice to clients across the region.”
The acquisition positions Affinia to continue delivering comprehensive accountancy and advisory services while leveraging the additional resources of a larger group. It reflects a broader strategy of growth through carefully selected partnerships that reinforce client service standards and regional coverage.
