Since joining ETL GLOBAL in 2024, Ad Valorem has accelerated its long-term growth strategy through a series of carefully selected acquisitions designed to enhance both regional scale and service excellence.

In 2025, the firm acquired Thompsons Accountancy Services Limited, strengthening its presence across Bedfordshire and further integrating its Milton Keynes and Cambridge operations into a unified regional platform.

This expansion continued in April 2026 with the acquisition of the highly respected Collett Hulance practice an established Bedfordshire firm with more than 80 years of heritage. The transaction further enhanced Ad Valorem’s footprint across the Oxford–Cambridge growth corridor and reinforced the firm’s position as a leading adviser to ambitious businesses throughout the region.

To date, Ad Valorem has completed four strategic acquisitions with the support of ETL GLOBAL reflecting the firm’s disciplined and highly successful expansion model.

Ad Valorem’s innovative business model’s strong growth trajectory and strategic M&A activity have received national recognition within the professional services sector. In 2025, the firm was awarded the Silver Award for Deal of the Year at the prestigious Accounting Excellence Awards, recognising both the quality of its transactions and the strength of its long-term vision.

Supported by ETL GLOBAL, Ad Valorem has continued to invest significantly in integrated technology platforms, digital infrastructure, and modern client solutions. These investments have enabled the firm to deliver a seamless, high-quality advisory experience while preserving the entrepreneurial culture of independence and personal relationships that define the business.

Ad Valorem’s continued success mirrors the wider momentum of the ETL UK group which achieved 38% year-on-year revenue growth to £155 million in 2026. As part of one of the fastest-growing international professional services groups, Ad Valorem combines the agility and personal service of an independent firm with access to global expertise, international connectivity, and significant strategic resources.
