The procurement process, conducted by Llywodraeth Cymru / Welsh Government, focused on providing guidance for marine Special Areas of Conservation (SACs) regarding nitrates. The title of the tender was "HRA Nitrates Guidance for Marine SACs" and fell under the services category within the environmental planning and urban planning services. The contract, awarded to DTA Ecology Ltd, was initiated on 1st October 2025 and is set to conclude on 27th February 2026. Based in Cardiff, the procurement was conducted via a direct method, bypassing competition due to its below-threshold value. The project forms part of the Welsh Government's ongoing initiatives, with particular relevance to local planning authorities in response to recent condition assessments.

Small and medium-sized enterprises (SMEs) like DTA Ecology Ltd, which focus on ecological and environmental advisories, would find this project aligns with their expertise. This contract not only offers a chance for firms to collaborate with central government but also represents a pathway to establish and deepen ties within the burgeoning niche of environmental planning, particularly concerning compliance with the Habitats Regulations. Businesses providing innovative and sustainable solutions will find this sector ripe for growth and collaboration.

## Notice

The aim of the contract is to provide advice to assist affected local planning authorities in responding to the recent publication of condition assessments by NRW relating to the impact of nitrates on marine Special Areas of Conservation. The study will use case studies to seek to identify what steps can be taken to enable affordable housing (including other development where possible) to come forward in compliance with the Habitats Regulations.
