Cognition Land and Water has extensive experience in the remediation and enabling of former gasworks sites across the UK. These complex brownfield projects typically present a legacy of heavy contamination (tar, hydrocarbons, PAHs, heavy metals, asbestos, cyanide, and NAPL), redundant gasholders and tanks, and challenging ground conditions. Our work enables safe redevelopment into residential and mixed-use schemes, often in highly constrained urban settings and near sensitive receptors such as rivers, canals, and existing housing.
Across multiple sites, our approach has consistently focused on:
We are currently delivering a comprehensive package of enabling and remediation works at King’s Road Park, Phase 4, in Fulham, on behalf of St William Homes. Our scope includes pile mat construction, anchored sheet piling, multi-level basement excavation, historical tar tank removal and contamination remediation on this highly constrained former gasworks site. In 2022/23, we successfully completed the contamination remediation, site turnover, and enabling works for the entire former Bow Common Gasworks site. In 2025, Cognition returned to this site and is carrying out additional enabling works on Phase 2 of the Bow Green development on behalf of St William Homes.
