Stockport, Greater Manchester — August 2026 — Drainage Advisory Services and Assistance Limited, known as DASA, has confirmed a recent change to its ownership structure, marking a new chapter for the specialist drainage, water and leak detection business. DASA now operates as part of Sigo Group.
DASA works with insurers, commercial clients and customers across a range of drainage, water and leak detection services, and has built a strong reputation for technical expertise, customer service and operational delivery.
Under its new structure, DASA continues to be led by its existing senior management team, with a clear focus on strengthening and growing the business. The business has already begun a round of significant investment in:
• IT systems and digital capability

• New and enhanced service offerings
As part of this next stage of development, Paul Greenwood has joined DASA as a shareholder, Client Services Director and member of the leadership team, bringing extensive industry experience, technical expertise and commercial knowledge to the business.

Chris Edwards, Managing Director of DASA, said:
“This is an exciting step for the business and gives us greater flexibility, renewed energy and a clear focus on delivering even more value to our customers and partners. Our commitment to customers remains unchanged — the same trusted team, the same values, and the same dedication to service. We’re pleased to welcome Paul Greenwood, Nick Allan and Lewis Dunstan to the business, and their experience will help us continue to invest in the right people, systems and technologies as DASA moves into its next phase.”
