Struggling with Odour Planning Conditions or Complaints?

Local authorities increasingly require an Odour Assessment for Planning when developments involve potential odour sources — such as restaurants, commercial kitchens, waste facilities, agriculture, or industrial processes.
Missing odour documentation or mitigation evidence can delay validation or trigger enforcement action.

ACP Consultants provide reliable, planning-ready odour reports and odour monitoring services to demonstrate compliance and prevent nuisance.
Our Odour Consultants handle every stage — from odour screening assessments and odour modelling studies to Odour Management Plans (OMPs) and mitigation strategies.

When Is an Odour Impact Assessment Required?

An odour impact assessment is typically requested during the planning process when a development is either producing odour or is located close to an existing odour source. For example, new restaurants, takeaways and food-led premises often require an assessment to demonstrate that extraction and filtration systems are adequate. 

Similarly, sites close to waste transfer stations, composting facilities, sewage treatment plants or farms may need to assess incoming odour risk before planning permission can be granted. Local authorities rely on this information to understand whether a proposal will create unacceptable nuisance for residents or conflict with neighbouring land uses.

Odour Management Plans (OMP)

An Odour Management Plan is a structured document that explains how a site will prevent, monitor and respond to odour emissions. It usually sets out the main odour sources, the control measures in place, and the procedures used to minimise risk during day-to-day operations. It also describes how complaints will be investigated and how issues will be corrected if odour problems arise.

Many councils now insist on a formal OMP as part of planning conditions, particularly for food premises, waste sites and facilities with ongoing operational emissions. Including a clear and professionally structured OMP can greatly strengthen a planning application.

What Is an Odour Assessment?

An odour assessment is a technical review that evaluates the likelihood of odour emissions affecting nearby homes or sensitive land uses. It considers where odours may originate, how they may travel, and the level of impact at surrounding receptors. 

Local authorities frequently require an odour assessment when a development involves food premises, commercial kitchens, industrial processes, waste sites, agricultural operations or any activity that could generate odours. 

The purpose of the assessment is to support your planning application with clear, objective evidence that the site is appropriately managed, and that the level of odour risk is acceptable.

Our Odour Survey Process

Our process is straightforward and designed to support planning requirements as quickly as possible. We begin with a free desktop review to understand your site, its surroundings and any potential odour sources. If a site visit is required, one of our consultants attends to observe operations, assess ventilation and extraction arrangements, and gather any necessary technical information. We then evaluate the odour risk using the latest guidance and modelling approaches.

Your completed report is delivered within 5–7 working days, clearly setting out whether mitigation is required and what steps are necessary to satisfy the planning officer.
