Commercial and industrial developments often require a noise survey and noise impact assessment to determine how noise from new or existing operations may affect nearby sensitive receptors. Our acoustic consultants undertake detailed noise monitoring of noise emitting plant or machinery and provide clear, evidence‑based noise reports to support planning applications, discharge of noise conditions, PPC Permits, and operational changes.

We work with developers, operators, planners and design teams for industrial and commercial sites to deliver reliable noise impact assessments and noise management plans, including all measurement data, acoustic modelling (where needed), and technical analysis required for submission to local authorities.

When is a Commercial Noise Assessment or Industrial Noise Assessment Required?

A commercial noise assessment or industrial noise assessment is commonly needed when:

  • A new commercial or industrial development is proposed close to residential or noise‑sensitive receptors and a noise impact assessment is requested for planning submission;
  • An existing site introduces new plant, machinery or operational processes;
  • A PPC Permit is being applied for, varied or maintained; or
  • A regulator or local authority requires a noise management plan as part of a planning consent or permit.

In these situations, our acoustic consultants carry out noise monitoring to determine baseline conditions and assess potential noise impacts from new or modified operations.

Our Approach: What is Involved in a Commercial Noise Assessment & Industrial Noise Assessment?

We take a clear and practical approach to industrial noise assessment and commercial noise assessment, broken down into the following stages:

Baseline Noise Monitoring

We undertake attended or unattended commercial and industrial noise surveys in line with relevant standards and regulatory guidance to capture daytime and night‑time background noise levels, or existing noise emission levels from in‑situ plant or machinery. Background noise monitoring locations are selected to represent the nearest and most exposed sensitive receptors.

Assessment Against Relevant Standards

Assessments are undertaken using recognised guidance such as BS 4142 for evaluating industrial and commercial sound. Depending on the development type, we may also use additional planning or sector‑specific guidance requested by the local authority.

Where assessment is required for PPC Permitting, the Environment Agency (EA), Scottish Environment Protection Agency (SEPA) and Natural Resources Wales (NRW) each provide their own guidance depending on where the site is located.

For sites in Scotland, we include relevant national guidance such as PAN 1/2011 Planning and Noise and its accompanying Technical Advice Note: Assessment of Noise.

Noise Modelling and Predictions

We undertake calculations or acoustic modelling to predict operational noise levels, including:

  • Fixed plant noise;
  • Vehicle movements;
  • Loading and unloading activities; and
  • Outdoor operations.

Predicted noise levels are compared against baseline conditions and relevant criteria to understand potential impacts on nearby receptors.

Mitigation and Design Advice

Where mitigation is required, we provide proportionate and practical recommendations, including:

  • Acoustic barriers or screens;
  • Plant and equipment selection;
  • Operational measures;
  • Building orientation and layout; and
  • Enclosure or attenuation options.

All findings are summarised in a concise noise report suitable for planning or PPC Permitting.

Experience

We have delivered industrial noise assessments and commercial noise assessments for a wide range of developments, including:

  • Industrial and manufacturing sites;
  • Commercial units and distribution centres;
  • Waste and recycling facilities;
  • Energy and utility infrastructure; and
  • Sites regulated under PPC Permits.

We understand the operational constraints of industrial environments and provide assessments that balance technical rigour with practicality.
