The United Kingdom has launched a public consultation on the future direction of its fertilizer regulations, open until May 13, 2026. The initiative aims to replace the outdated 1991 framework with a modernized system aligned with broader objectives of regulatory simplification, product safety, and environmental performance.

A central feature of the proposal is the shift toward a “Conformity Assessment” model, which would move away from detailed lists of authorized materials toward a system based on verifying product performance and compliance. This approach is presented as more flexible and better suited to innovation, including the development of low-carbon and low-emission fertilizers.
However, the current outline raises concerns regarding the scope of this flexibility. Under the proposed framework, only inorganic fertilizers, liming materials, inhibitors, and blends would be covered initially. A broad range of other products – including organic and organo-mineral fertilizers, biostimulants, soil improvers, and growing media – would remain excluded. In addition, only inputs derived from virgin chemical materials would be permitted, effectively excluding recycled or secondary raw materials that have not achieved “end-of-waste” status.
This limitation appears to contrast with the stated ambition to support innovation and circular economy solutions. By focusing on conventional inputs, the proposal may not fully reflect ongoing developments in nutrient recycling and sustainable fertilizer technologies. At the same time, the consultation includes a separate questionnaire on bio stimulants, suggesting that additional regulatory pathways may be considered in the future.
The reform is being developed as a joint initiative across England, Scotland, Wales, and Northern Ireland, with the objective of establishing a unified UK-wide regulatory framework. Stakeholders are invited to provide input on the technical parameters of the Conformity Assessment system, including options for self-declaration, third-party verification, and the role of standards.
Another open question concerns the relationship with the European Union framework. The consultation seeks views on whether CE-marked fertilizing products should continue to be recognized in the UK, highlighting the importance of maintaining market access and regulatory coherence.
Overall, the consultation represents an important step in redefining fertilizer policy in the UK. Its final design will determine how effectively the new framework can balance regulatory simplification, environmental objectives and support for innovation in the fertilizer sector.
