Irwin Carr provides specialist environmental consultancy services for agricultural developments, supporting farmers, planners, and design teams through the planning and regulatory process. Our work focuses on delivering clear, proportionate, and evidence‑led assessments that enable sustainable agricultural development while protecting nearby communities and sensitive environments.

Air Quality & Ammonia Assessment

Irwin Carr has extensive experience delivering air quality impact assessments for poultry, pig, and cattle units, with particular expertise in ammonia emissions and nitrogen deposition. Assessments are undertaken in line with current regulatory guidance and are routinely submitted to Planning Authorities, Environmental Health Services, NIEA, EPA, and Shared Environmental Services.

We provide both screening assessments and detailed modelling, depending on project scale and sensitivity.

Land‑Spreading & Cumulative Impact

Where required, Irwin Carr undertakes ammonia and nitrogen deposition assessments for land‑spreading of manure, slurry, or digestate, including cumulative assessment of multiple landbanks.

This ensures off‑site agricultural activities are appropriately addressed within planning submissions and regulatory review.

Agricultural Noise Assessment

Irwin Carr provides noise assessments for agricultural buildings and operations, including pig and poultry housing, feed systems, plant, and vehicle movements.

Assessments are tailored to rural settings and focus on protecting residential amenity while recognising the operational needs of agricultural enterprises.

Planning Support & Appeals

We work closely with planners, architects, and regulators to ensure agricultural proposals are clearly justified and technically robust. Our experience includes responding to Environmental Health queries, supporting planning appeals, and providing concise technical advice to address objections and third‑party concerns.
