Join us for an unforgettable night of celebration and connection at the ISWA 2026 Gala Dinner, held in the historic surroundings of Guildhall, London.

The ISWA Gala Dinner offers an opportunity to step away from the Congress programme and enjoy an evening of fine dining, cultural heritage and meaningful conversation.

Guests will be welcomed into one of London’s most iconic venues for a formal dinner, accompanied by live entertainment and moments of reflection on the progress and ambition of our sector.

The Gala Dinner is more than a social highlight; it’s a celebration of international collaboration, professional excellence and our shared commitment to moving the world beyond waste.

Built between 1411 and 1440, Guildhall was designed to reflect the power and prestige of London and its leaders. Set in the heart of the city, this historic landmark has been at the centre of London’s civic life for over 800 years.

Its grand architecture and rich heritage provide a fitting backdrop for an evening that brings together leaders, innovators and changemakers from across the global resource and waste management community.

The ISWA Gala Dinner offers a prestigious opportunity to showcase your brand to an engaged global audience in a historic venue right in the heart of London.
