Quercus International is pleased to announce that a team led by Paul Warren originated the acquisition of Collett Hulance Accountants Limited (“Collett Hulance”) by Ad Valorem Accountancy Services Limited (“Ad Valorem” or the “Group”).

Based in Milton Keynes, Ad Valorem is a regional leading firm of accountants, auditors, tax and business advisors that has provided innovative accounting services to its clients for +20 years. Collett Hulance is an experienced team of accountants, specialising in working with owner-managed businesses in Bedfordshire, Milton Keynes and nearby areas.

The acquisition of Collett Hulance will strengthen Ad Valorem’s presence and build on its existing footprint in Bedfordshire created as part of the acquisition of Thompsons Accountancy Services in 2025. Furthermore, it will connect its Milton Keynes and Cambridge offices into a more integrated regional platform. With the backing of ETL Global UK, the combined firm can invest for the long-term, while retaining strong local leadership, culture and client relationships.

Nigel Adams, Founder and Managing Director of Ad Valorem, said: “We are delighted to welcome Collett Hulance to the Ad Valorem Group. Bedfordshire is entering a period of significant growth, driven by major inward investment, including the Universal Studios development. Through the combination with Collett Hulance, we are better positioned to support businesses with broader advisory services, scalable infrastructure and specialist expertise.”

Paul Warren, Quercus International, commented: “We are delighted to have originated and supported Ad Valorem through this acquisition. The strong strategic fit is evident. We are excited about the benefits the combined business will deliver to its existing and future clients as they seek to respond to the significant growth opportunities present in the local market.”
