Green Zone Surveys

A North East-based building compliance group comprising Green Zone Surveys and its subsidiary Walker Maintenance (trading as Enviroduct), has been acquired by Vadella – an acquisitive UK testing, inspection, and compliance group backed by international investment firm Blixt.

In a deal supported by our Corporate Finance team, the acquisition represents Vadella’s latest investment as it consolidates and grows a network of inspection-led businesses serving the UK’s built environment.  The transaction provides significant backing for the group’s existing management team to accelerate the growth of both entities.

Based in the North East, Green Zone Surveys specialises in testing, inspection and compliance (TIC) services across commercial and business properties, while Enviroduct provides professional kitchen ductwork and ventilation cleaning services for a broad base of national clients. The deal marks the next stage in the group’s growth journey under Chief Executive Callum Thompson and the group’s leadership team. The deal will enable existing shareholders to realise their investment, while securing additional capital and support for further organic growth and selective acquisitions.

Our Corporate Finance Newcastle-based team, led by Partner Phil Williams with support from Associate Directors Mo Miah and Graham Brown, acted as lead sell-side advisers. The team supported the shareholders throughout the transaction process, managed buyer engagement and negotiated heads of terms, before seeing the deal through to completion.

Phil Williams, Partner at FRP Corporate Finance, said: “This transaction is another sign of the continuing resilience of the lower mid-market for UK deals. Quality businesses in growing compliance-led sectors, led by ambitious management teams, continue to attract strong interest from well-backed investors. Blixt and Vadella have thrown their weight behind Green Zone, backing Callum and his team to continue their tremendous growth story and bringing further inward investment into the North East.”

Callum Thompson, Chief Executive of Green Zone Surveys, said: “Joining the Vadella platform marks an exciting new chapter for our people and clients. The investment will help us scale our testing, inspection and compliance services, broaden our specialist ductwork and ventilation offering, and pursue targeted acquisitions – all while maintaining the high standards our customers expect. We have worked with FRP Corporate Finance for a long time and the team’s advice, energy and coordination from day one were invaluable in getting us to a great outcome.”
