Achieving Nutrient Neutrality

March 11, 2025

Achieving nutrient neutrality is a challenging task, and is one that developers all over the country have battled to achieve over the last 5-6 years. In March 2022, Natural England issued a directive to Local Planning Authorities, County Councils, the Environment Agency, the Planning Inspectorate, Natural Resources Wales, and DLUHC stating that, in specific river catchments, developments should not be permitted if the LPA cannot definitively ensure that it will not adversely impact protected environmental sites due to increased levels of nitrate and/or phosphate.


While the current approach is efficient, robust, and objective, it can also be slow, costly, and overly complex—leading to potential project delays and increased expenses for housing developers.


To address these challenges, the government released the Planning Reform Working Paper in December 2024. This initiative aims to unlock approximately 28,000 homes across seven areas in England that had been stalled due to nutrient neutrality concerns, backed by £47 million from the Local Nutrient Mitigation Fund.

At its core, nutrient neutrality is about safeguarding sensitive habitats and species vulnerable to changes in water quality. Excess nutrients such as phosphate and nitrogen can lead to eutrophication, disrupting mineral balances and causing ecological degradation in water systems. Ensuring that new developments do not contribute to this issue is critical, but proving compliance with nutrient neutrality requirements can be a complex and evolving challenge for developers.


The assessment process itself is subject to shifting environmental regulations and policies, creating uncertainties and potential delays depending on the scale and location of a development. Despite the experience gained over the past few years, straightforward solutions remain elusive. Many developers continue to face financial, technical, and operational pressures when working to meet these stringent environmental standards.


Looking ahead, the key to navigating nutrient neutrality lies in balancing environmental protection with the practical realities of development. Aligning proposals with Natural England’s guidelines, conducting high-level Nutrient Assessments early in the planning process, and engaging stakeholders to align regulatory expectations can all contribute to a more streamlined approach.


While there is no quick or easy fix, having the right expertise from the outset can make a significant difference.


Our specialist water resources team combine an in-depth understanding of natural water systems with experience across a range of development and agricultural projects, offering an independent perspective on the challenges at hand. By starting on the right path with the right support, developers can improve their chances of achieving nutrient neutrality in a cost-effective and efficient manner.

Protecting UK agriculture against a changing climate

By Rachael Plant • October 23, 2025
As the threat of climate change continues to increase, the frequency of extreme weather events is rising across the UK. With wetter winters but warmer, drier summers expected to persist, the risk of drought will grow, creating significant challenges nationwide. While the UK climate can be unpredictable, the impact of drought is evident and cannot be ignored. Following several drought declarations and water restrictions enforced throughout 2025, farmers across the UK continue to contend with drained reservoir levels and heightened demand for irrigation, resulting in lower crop yields, fragile water sources, and growing concern about the future of British agriculture. Our team of water resource experts has been working within the agricultural industry for many years, supporting the implementation and management of sustainable water resources. We asked Principal Water Resources Specialist, Tamsin Morey , for her thoughts. Tamsin, what danger is the UK farming industry already experiencing?

Richmond Bike Park Success

By Rachael Plant • September 25, 2025
Envireau Water are thrilled to have contributed to the recent successful planning application for the construction of a community bike park in Richmond, North Yorkshire. Louise Raine, a local to the area, first set up the campaign after realising there were no 'safe and purpose-built spaces' for her children and other families. In collaboration with the local community and town council, Envireau Water volunteered to provide high-level technical support on flood risk and drainage solutions, following concerns raised by a lead regulatory authority. Hydrologists, Mairi , Lee , and Michael conducted a review of flood risk, drainage pathways and soil infiltration potential. Upon developing the drainage strategy and producing pre- and post-development 2D runoff modelling, it was discovered that the proposed location had no significant risk. By investigating the soil types and overland flow pathways, it was also noted that the suggested drainage strategy would have both a flood risk benefit and an environmental benefit of enhancing the ecology and biodiversity of the land.

Anna Hitchmough joins Envireau Water

By Rachael Plant • July 22, 2025
We are excited to welcome Dr Anna Hitchmough to our growing team, who recently joined Envireau Water as a Principal Technical Specialist. With over 25 years of consultancy experience in hydrogeology, Anna brings a wealth of expertise to our team. Anna joins us from Carbon Zero Consulting/RSK Geosciences, where her career has centred around ground-source heat pump systems. In her most recent role, Anna chaired RSK's Heat Decarbonisation Working Group and Hydrogeology Working Group. Anna brings extensive experience in quantitative risk assessments and NAPL characterisation and has completed significant work on several contaminated land projects, having previously served as Chair of the Geological Society's Contaminated Land Group. Anna's academic background stems from the University of Newcastle where she completed an MSc in Hydrology, followed by a PhD in Hydrogeology at the University of Birmingham. She is also a chartered geologist.
