Generators, pumps and substations run noise into a shift most sites have never measured. Run the free 60-second check before you spec anything.
Background hum hides a real number.
Generators, pumps and substations run a constant noise most sites have never had measured — it rarely feels dramatic enough to flag on its own.
Generators and compressors run continuously.
Steady, unbroken exposure for anyone working near plant.
A plant room reflects as much as it generates.
Hard surfaces in a confined space add to what the machinery makes.
Real figures for your own plant.
Not a manufacturer’s spec-sheet number measured somewhere else.
No UK figure exists yet for a generator, pump or substation — that’s exactly what one assessment measures.

Utilities hearing-loss prevalence*
*A US CDC analysis of 1.3 million worker audiograms found 25% noise-induced hearing loss prevalence in utilities workers (37% in hydroelectric power generation, 29% in steam/air- conditioning supply) — a real, named third-party statistic, not a UK HSE figure and not a dB(A) sound-level reading. No UK-primary dB(A) range for pumping stations, generators or substations has been sourced yet — your own site’s figure is only known once it’s actually measured.
Background hum hides a real number
Measured properly. Proven properly. Plant by plant.
Generators, pumps and substations run a constant noise most sites have never had measured — it rarely feels dramatic enough to flag on its own.
The Control of Noise at Work Regulations 2005 apply whether the noise source is a generator, a pump, or a substation — regardless of whether a sector-specific guidance figure exists.
Real exposure levels for your own plant and switching/pumping areas, checked against the 80 / 85 / 87 dB(A) action and limit values — not a generic industry figure.
What one assessment actually tells you
One assessment gives your site a real figure, not a borrowed one from another country's study — your own generator, your own pump room, your own substation.
What people ask
Is there a UK figure for generator or pump noise?
No sourced UK-primary dB(A) range has been confirmed yet for pumping stations, generators or substations — which is exactly why an assessment of your own plant matters rather than relying on a borrowed figure.
Does the regulation still apply without a sector figure?
Yes. The Control of Noise at Work Regulations 2005 apply regardless of whether a sector-specific guidance figure exists.
Is a desk-based estimate good enough?
No. A real assessment is based on your own plant and your own site, not a generic industry figure.
Is seeing whether I have a problem free?
Yes. Seeing whether there’s a problem is free. You only pay once you know you want the full report.
Is this a guarantee my site is compliant?
No. It’s a calibrated assessment against the real action and limit values, not a certification or a legal guarantee.
