RESTAURANTS · TAKEAWAYS · EXTRACTION SYSTEMS
Commercial-kitchen noise & odour assessments.
Design kitchen extraction around the business and its neighbours. ACP assesses noise and odour risks, reviews the proposed system and provides clear technical advice for planning.
Connect cooking activity, extraction performance and nearby sensitive uses before the duct route, fan and discharge arrangement are fixed.
Read the illustration description
Section through a restaurant kitchen with cooking canopy, grease capture, odour-control equipment, fan and attenuation, a vertical discharge and a neighbouring upper-floor window. Sound and odour follow different paths.
DEFINE THE BRIEF
Support the business.
Protect the neighbouring use.
Cooking type, throughput, hours and the surrounding buildings shape the assessment. We review the actual operation and the proposed extraction design, including homes above or beside the premises.
Noise & odour for planning
Bring the two assessment scopes together around the proposed use, extraction system and local authority request.

Share the site, cooking methods, hours and extraction proposal. We will identify the required noise and odour assessment scope.
Include any existing report, planning condition or environmental health comments.
SURVEY · ASSESS · COORDINATE
Understand the operation.
Coordinate the system.
We start with what will be cooked, how much, when and how emissions will be extracted. Then we connect the environmental assessment with the designer’s proposed equipment and layout.
Define the business and sensitive uses
Review the menu, cooking methods, anticipated throughput, hours and nearby homes or other sensitive locations. Include premises above the kitchen and future uses where relevant.
Review the extraction design
Obtain the canopy, duct, fan, treatment and discharge details. Identify equipment data, access, plant locations and the assumptions that need confirmation.
Assess noise and odour separately
Use the relevant acoustic method and a proportionate odour assessment. Consider existing conditions, the source-to-receiver paths and any further evidence needed.
Set out the coordinated response
Describe practical controls, performance requirements and operating assumptions. Record maintenance needs, design dependencies and any verification or condition response.
Adding treatment or attenuation can change pressure losses and the fan duty. The extraction designer must coordinate airflow and system performance with the environmental recommendations.
THE DETAILS THAT SHAPE THE ANSWER
Follow the emissions
from cooking to the neighbour.
An assessment needs more than a fan model and a filter description. We review the linked questions that determine whether the proposal can be supported with meaningful evidence.
| Consideration | What the assessment needs to address |
|---|---|
| Cooking and throughput | Identify cooking methods, menu, equipment and expected intensity. Frying, grilling and other processes can create different odour and grease-control demands. |
| Operating hours | Consider preparation, service, cleaning and plant run-on, including evening or night-time periods. The extraction may operate beyond the customer opening hours. |
| Sensitive receivers | Identify nearby windows, balconies, ventilation intakes and occupied premises, including homes above or beside the unit. Review the relevant surrounding building geometry. |
| Acoustic pathways | Consider discharge noise, fan casing breakout, duct radiation and structure-borne transmission where relevant. One attenuator does not necessarily address every path. |
| Treatment and discharge | Review grease control, odour treatment, airflow, discharge height, direction and location. Specify the assessment assumptions and obtain the designer’s supporting performance details. |
| Operation and maintenance | Record inspection, cleaning and replacement requirements. A treatment system that is poorly maintained may not deliver the performance assumed in the assessment. |

EVIDENCE INTO ACTION
Treat the source.
Control the paths.
Effective advice considers the whole system and its operation. We identify the measures needed for the assessment, then coordinate the environmental brief with the specialist designer.
Address the relevant sound paths
Review suitable equipment, attenuation, casing or duct breakout and vibration isolation. Match measures to the actual source, receiver and operating scenario.
Match treatment to the cooking
Consider appropriate grease and odour controls for the operation. Obtain system performance and maintenance information rather than rely on an unspecified filter label.
Review the outlet in context
Assess the relationship with buildings, openings and intakes. A taller duct is not automatically sufficient, and a convenient wall outlet may create avoidable exposure.
Our environmental assessment informs the performance brief. Detailed extraction design, fire safety, ventilation compliance and installation remain separately defined responsibilities unless expressly included.
THE RIGHT METHOD FOR THE RIGHT QUESTION
Guidance, scope
and the local requirement.
We identify which guidance and requirements apply to your project. The assessment method, the planning decision and any other statutory process each have their own role.
Commercial-kitchen extraction guidance
Use relevant current EMAQ+ guidance and the authority’s submission requirements to inform the design and assessment. Confirm the edition and scope accepted for the actual application.
BS 4142 and plant noise
Where applicable, assess industrial or commercial sound using the relevant background, sound character and context. Agree any specific local criterion rather than assume a universal limit.
Odour assessment for planning
The assessment should be proportionate to the operation and risk. Depending on the proposal, this may involve a qualitative risk assessment, supporting design evidence or more detailed analysis.
Planning, licensing and nuisance
These are related but separate matters. An environmental report supports the agreed planning scope; it does not grant permission, replace licensing requirements or guarantee that complaints cannot occur.
DEFINED DELIVERABLES
A report that connects
operation, design and controls.
Agree whether the submission needs combined noise and odour evidence, a focused technical assessment or a response to a specific extraction condition.
Operational brief
Cooking methods, throughput, operating hours and the relevant business assumptions.
Site and sensitive uses
Receiver locations, surrounding buildings and relevant existing conditions.
Noise assessment
Source data, survey evidence where needed, calculations, character and contextual findings.
Odour assessment
Assessment of the source, pathways, sensitive uses and the basis of the risk judgement.
Control strategy
Required acoustic measures, treatment and discharge recommendations with design inputs identified.
Management and next steps
Maintenance assumptions, outstanding information and any verification or council response included.

Clear answers.
A better project brief.
Share the authority’s request if you are unsure what is required. We can help distinguish the assessment, design advice, monitoring or verification that your project needs.
Do restaurants and takeaways need noise and odour reports?
Requirements depend on the proposal, site and authority. New uses, extraction changes and nearby sensitive premises can prompt requests for both assessments. Share the planning or environmental health comments so we can define the required evidence.
Can one report cover noise and odour?
Yes, where that suits the submission. The report should still explain the two assessment methods and findings clearly. Acoustic and odour controls need coordination but do not answer the same question.
Is a carbon filter enough to control odour?
The treatment must suit the cooking, airflow and required performance. A generic carbon-filter statement is not enough to establish an adequate design. Grease control, treatment specification, maintenance and discharge arrangements all matter.
Will an attenuator remove every noise issue?
No. It can address a particular airborne path, but casing breakout, duct radiation, other plant and vibration may remain relevant. We identify the contributions and specify the acoustic requirements for the design team.
Does the discharge always have to be above the roof?
The appropriate arrangement depends on the guidance, local requirements, surrounding geometry and proposal. We review the actual outlet and sensitive locations rather than prescribe a universal height for every site.
What if there are flats above the kitchen?
Tell us at the outset. Windows, ventilation intakes, occupied rooms and the structure connecting the premises can affect the assessment. The design may need both airborne and structure-borne noise consideration alongside odour exposure.
Can you review an extraction system that is already installed?
Yes. We can review available design details, actual operation and the reported concern. Surveys or further investigation may be needed. Any remedy will depend on the evidence and the practical constraints.
Do we need dispersion modelling?
Not every kitchen requires detailed modelling. We scope a proportionate approach using the operation, site and authority request. More complex or higher-risk proposals may need additional analysis.
Can you design and install the extraction system?
Our agreed work provides environmental assessment and acoustic or odour-control advice. Detailed mechanical design, procurement and installation are separately scoped specialist responsibilities.
What should I send for a quote?
Submit the postcode, type of food, cooking methods, anticipated hours and any council request. We can then request plans, fan data, treatment specifications and discharge details.
