Water & Nutrient Neutrality

Nutrient pollution and water scarcity are two problems affecting the UK. Whilst they are two different issues one solution for both of them is to reduce water wastage. Over 120,000 properties are on hold due to complex water and nutrient neutrality challenges and Control Flow can offer a solution to unlock the planning permission for these builds.

Control Flow technology is installed by expert Cenergist engineers and trusted by our clients.

Our Turnkey Solution

Our patented devices regulate the incoming flow of mains water, resulting in a reduction in water wastage which can be caused by the natural fluctuation in mains pressure and flow. By installing these devices in properties water consumption can be reduced by on average 84 litres per property per day.


In order to achieve water or nutrient neutrality for your development we can install in your existing properties, or we can identify additional properties for installation. Our Control Flow service offers a simple, cost-effective, and Natural England approved turnkey solution for earning mitigation credits and unlocking developments.

Our technology has already delivered tangible results for residential developments and commercial buildings, unlocking multiple build sites, including affordable housing schemes and large-scale commercial premises

Nutrient Neutrality

Nutrient pollution is a major environmental issue affecting freshwater habitats and estuaries and whilst action has been taken by the government to tackle the problem, restrictions were put in place to restrict building in some of the worst affected areas until the mitigating actions have had time to take effect.

It was thought that extra wastewater from new housing developments could make the situation worse and undermine the ongoing efforts to recover the sites. The installation of Control Flow HL2024 ®, can significantly reduce the volume of nutrients created by new and existing properties in the affected areas by reducing the water usage in those areas.

Control Flow devices can be used as mitigation measures in nutrient neutrality areas, saving on average 84 litres of water wastage per household per day, and these devices have been used to unlock planning permission for over 1,000 homes.

Developers seeking to progress their projects in nutrient neutrality areas can now also purchase nutrient mitigation credits from us - generated through our water efficiency projects. These credits offer a certified solution for offsetting nutrient impacts, enabling developments to move forward without requiring immediate access to housing stock for technology installation. Get in touch today to learn more about how our nutrient mitigation credits can support your development plans.

Water Neutrality

Control Flow has been approved by Natural England as a mitigation solution for water and nutrient neutrality. Average savings are 36 litres per person per day. Control Flow HL2024® patented devices deliver consistent, tangible reductions in water usage in both domestic and commercial properties. The controlled, optimal flow delivered by our devices reduces pressure fluctuations that naturally occur in the mains supply throughout the day, thereby reducing water wastage.

Our patented Control Flow HL2024® technology outperforms solutions such as rainwater harvesting and greywater recycling schemes in both speed of delivery and cost efficiency.

Our team of experts will help you identify how to achieve the offsetting credits your development requires and then our experienced engineers install our patented Control Flow HL2024® technology.

Future Housing and Water Scarcity: The Growing Challenge

This map illustrates the areas in England where ambitious housing targets are under threat due to critical water shortages, particularly in the south-east. Local authorities in cities like Cambridge, Ipswich, and Portsmouth face significant challenges in meeting government housing goals while ensuring a sustainable water supply. Without intervention, these shortages could stall over 60,000 new homes, placing additional strain on existing infrastructure. Control Flow’s innovative, proven technology offers a practical solution, enabling sustainable housing growth by reducing water consumption without requiring changes in behaviour. By adopting smart water management strategies, developers and councils can unlock stalled projects and secure long-term water resilience.
