RSE, the UK’s leading provider of modular and sustainable water treatment solutions, has released its financial results for the year ending 31 March 2024, showcasing a 30% increase in revenue to £257.2 million (2023: £197.7 million).
Operating profit also grew to £19.9 million in the period (2023: £13.9 million) strengthening RSE’s position as a market leading technology provider to the water sector. While the business has seen growth in all territories, RSE’s capabilities are now widely recognised across England and Wales, building on the strength of proven expertise and client relationships in Scotland.
RSE’s ability to innovate and deliver industry-leading products and solutions has fostered new customer partnerships across municipal and industrial markets, generating strong demand for its offerings among all clients. This expansion, combined with strategic acquisitions, marks a significant shift for RSE as its footprint across the UK grows beyond established Scottish roots.
Investment in the Future of Water Technology
The company completed two acquisitions in the period to further strengthen capability, although the majority of the growth in the period was organic, linked to RSE’s strategy to increase revenues across the English municipal water companies. To support growth, all the company’s retained profits were reinvested in product development and innovation, leading to a step change in its offering to the water technology sector.
This included the launch of new modular water treatment plants featuring an 85% reduction in CO₂ emissions over traditional solutions. Deployed in half the time and supported by innovative commercial models that ensure cost certainty, RSE is at the forefront of driving efficiency across the UK’s water sector.
Stephen Slessor, RSE’s Chief Executive Officer, said:
“Our focus on driving innovation, sustainability, and creating strong customer partnerships, has delivered significant organic growth in England and Wales, establishing this as a thriving region and a cornerstone of our future success. By combining modular engineering, cutting¬ edge technology, and sustainable practices, we are transforming how water treatment facilities are designed and delivered, creating tangible environmental and economic benefits.
“We are excited about the future as we continue to scale our operations, invest in new products, develop talent and lead the industry toward a more sustainable future.”
