Ofwat will shortly set out plans to launch the Water Efficiency Campaign, a bold national behaviour change campaign to improve water efficiency across England and Wales, backed by a confirmed budget of up to £75 million over five years.
Ahead of going out to tender, the water sector’s economic regulator is holding an in-person launch event in central London on 10 July 2025 (10:00-13:00) for suppliers hear about Ofwat’s vision for the campaign, meet Ofwat's marketing team, explore opportunities to get involved, and connect with others across the industry and water/ utilities sector.
Announcing the launch in a planned procurement notice, Ofwat said:
“This is more than a campaign, it's a once-in-a-generation opportunity to drive real, lasting change. Backed by unprecedented collaboration and investment, the momentum is strong. Ofwat and the water sector's ambition are sky-high.”
Ofwat's Head of Marketing Campaigns will be explaining technicalities, including the procurement route, contracting arrangements and answering questions from attendees before the Invitation to Tender (ITT) goes live.
