Executive Summary
As part of a strategic water reduction initiative, Grosvenor Estates partnered with Propelair to upgrade washrooms at its London head office. By installing 31 ultra-low-flush Propelair toilets, Grosvenor Estates achieved major water and carbon savings, reduced operating costs, and delivered improved hygiene performance across the building.
Client Profile
Grosvenor Estates is a leading UK property owner and developer, headquartered in central London, managing a diverse portfolio of premium commercial buildings. Operating high-occupancy office environments, water efficiency is critical to controlling operating costs, meeting sustainability commitments, and reducing environmental impact across its London estate while setting a benchmark for responsible property management.
Challenges / Pain Points
At its London head office, Grosvenor Estates faced rising water consumption driven by outdated 7-litre flush systems, leading to increasing utility costs and avoidable environmental impact. High washroom usage placed pressure on maintenance teams through blockages, downtime, and hygiene concerns, while growing ESG expectations demanded measurable reductions in water use, carbon emissions, and operational inefficiencies across the building.
The Propelair Solution
To address these challenges, Grosvenor Estates installed 31 Propelair ultra-low-flush toilets at its 70 Grosvenor Street headquarters. Each unit uses just 1.5 litres per flush, combining water with displaced air to deliver powerful, hygienic performance. This retrofit-ready solution was selected to deliver immediate, measurable water savings while improving washroom reliability, hygiene standards, and long-term operational efficiency.
