What it covers
What drives a fair workplace noise survey price
There is no single right price for a workplace noise survey. A small single-shift workshop is a very different piece of work from a multi-shift production facility with 200 employees, mobile workers and peak-noise tasks. A fair price requires a fair scope — and that starts with a short scoping conversation, not a published number.
This page sets out the cost factors honestly so you can budget realistically. For the underlying service itself, see workplace noise surveys and the wider noise survey services portfolio.
Cost factors
What drives the cost
Site size and complexity
Floor area, number of buildings and the diversity of machinery and processes.
Worker groups (SEGs)
Number of similar exposure groups that need representative measurement and dosimetry.
Shift pattern
Single shift, multi-shift, night work and weekend operations all affect on-site time.
Personal dosimetry volume
How many workers need dosimetry, and across how many shifts, to be representative.
Peak or machinery work
Whether dedicated peak (LCpeak) or machinery source measurements are included.
Reporting depth
Standard CNWR 2005 report, HSE-style report, multi-site rollup or audit-ready dossier.
Scoping
What we ask before quoting
- Number of employees and workforce groups
- Site floor area and number of buildings
- Machinery / process inventory
- Shift pattern and operating hours
- Existing assessment age and content
- Hearing protection and zone arrangements
- Any complaints, audiometric flags or HSE engagement
- Reporting needs (group HSE, insurer, planning)
Process
How quotation works
- 1
Scoping call
A short call to understand the workforce, the site and the question to be answered.
- 2
Walk-through (where useful)
On larger or more complex sites, a brief walk-through gives the most accurate scope.
- 3
Written scope
We send a written scope setting out method, on-site days, deliverables and any caveats.
- 4
Fixed quotation
A fixed price against that scope, with any optional add-ons itemised separately.
- 5
Booking
Site dates booked, calibration arranged and a measurement plan confirmed before arrival.
Included
What a quote typically includes
- Walk-through and measurement plan
- On-site Class 1 sound-level measurement
- Personal noise dosimetry as scoped
- Calibration and traceability
- LEX,8h and LCpeak calculations
- Hearing protection adequacy review
- Written CNWR 2005-aligned report
- Debrief call with the responsible person
Add-ons
Common add-ons (priced separately)
- Machinery noise surveys for specific cells
- Dedicated peak noise assessment
- Workplace noise mapping
- Hearing protection fit programme
- Training for supervisors and operators
- Audiometric trend review with OH provider
- Multi-site rollup reporting
- Retained consultancy
Avoiding waste
How to keep the cost down without compromising the assessment
- Provide an accurate workforce / process list early
- Plan around representative production days
- Group dosimetry into one or two visits
- Combine periodic re-assessment with control verification
- Schedule shifts in a single booking window where possible
- Reuse representative existing data where traceable
FAQ
Workplace noise survey cost — frequently asked questions
How much does a workplace noise survey cost?+
Cost varies with site size, the number of workers and similar exposure groups to be assessed, shift pattern, the volume of dosimetry required, whether peak or environmental components are in scope, and travel. We do not publish fixed prices because a fair price requires a fair scope — we provide a written quotation after a short scoping conversation.
What drives the price?+
Principally: the number of worker groups, the size and complexity of the site, the number of shifts that need to be covered, the amount of personal dosimetry, the need for machinery or peak measurements, the depth of reporting expected and any travel or out-of-hours requirements.
Do you publish a price list?+
No. Published price lists tend to mis-scope: small sites pay too much and large sites get an insufficient assessment. We prefer to quote against the work that is actually needed, with the scope and method written down explicitly.
Is a small business cheaper to assess?+
Generally yes — fewer workers, fewer exposure groups, less dosimetry, smaller floor area, and often a single shift. A small workshop typically needs one site day plus reporting. We confirm scope before quoting.
What does the quote include?+
Walk-through, on-site measurement, calibration, dosimetry where appropriate, exposure calculation, control review, hearing protection adequacy, a written report and a debrief call. Any additions — peak work, machinery surveys, training — are itemised separately.
Do you offer fixed-price assessments?+
Yes, once scope is confirmed. A fixed price gives both parties certainty and avoids end-of-project surprises. Where work is genuinely uncertain (for example a complaint-led investigation) we use a clearly capped time-and-materials approach.
Are there ongoing costs?+
Workplace noise assessments are reviewed at least every two years and sooner where change occurs, so there is a periodic re-assessment cost. Where a hearing conservation programme is in place, retained consultancy may also be included.
