We’re excited to share that PK Group has joined Affinia, strengthening our position as one of the UK’s fastest-growing, fully integrated accounting, tax, and business advisory firms in the Top 50.

PK Group is a well-established team of accountants, tax advisers, and payroll specialists with offices based in Richmond and Woking. Their expertise and local presence perfectly complement our plans to expand across London, East Anglia, and the South East.

With PK Group on board, our Affinia team now includes more than 600 talented professionals, all committed to delivering exceptional service and helping clients achieve their goals.

Rob Harden, our Chief Development Officer says:

“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.” 

“We carefully considered collaborating with culturally aligned firms that would complement our approach and enable us to continue providing an exceptional service to our clients while also benefiting from the additional resources of a larger group. 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.”
