Fri, 05 Dec 2025 | BUSINESS SALE
A South East-based accountancy firm has been acquired by growing national group Affinia. PK Group has offices in Richmond and Woking, Surrey and is well known in the area for its accountancy, tax advisory, payroll and business finance services, having built a strong reputation for its strategic financial guidance and client-centred approach.
The firm becomes the latest to be acquired by Essex-headquartered Affinia, which has established itself as one of the UK’s fastest-growing accountancy, tax and business advisory groups. In 2025, Affinia has already acquired Kent-based Opass Billings Wilson & Honey and Sutton firm Clarkson Hyde.
The acquisition significantly strengthens Affinia’s presence across London, the South East and East Anglia, bringing its office footprint to 12 and taking its total number of professionals to more than 600 across the wider group.
PK Group founder and Chief Executive Patrick Kennedy stated: "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 benefitting 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."
Affinia Chief Development Officer Rob Harden added: "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."
Affinia was launched in December 2024 by LB Group, the chartered accountancy services portfolio business of private equity buy-and-build specialist Sovereign Capital Partners. Sovereign had initially backed LB Group in May 2023, subsequently completing six acquisitions, which were subsequently integrated with LB Group to form the Affinia group.
