CL:AIRE hosted another successful members' networking event, this time in Bristol at Racks Bar and Kitchen. The evening brought together professionals from across the sector for relaxed, informal conversation. CL:AIRE Members enjoyed small‑group discussions around current industry challenges, and it was great to see new connections being made too. The atmosphere was friendly and collaborative, with many people reconnecting with former colleagues while also making valuable new contacts over food and drinks.

A big thank you to our sponsors, DDE Remediation Solutions, Geosyntec Consultants, Remedia Group and UK Remediation for making the event possible. These networking evenings continue to provide a valuable space to develop relationships, explore new business opportunities and stay close to the latest thinking in our sector.

CL:AIRE will be hosting our Summer event on 4 June 2026 at De Hems Dutch Café Bar, London. If you are interested in coming along, or in providing sponsorship, please complete the registration form.
