What a survey actually finds

Four things a single number hides

These come up on almost every site we measure, and none of them show up in one daily figure. Tap or hover a card to see why each one matters.

The loudest hour is not the average hour

Why it matters →

A daily average can sit under 85 dB(A) while an hour of it sits over 95. The plan has to deal with the hour, not the average.

Protection is measured at the ear

Why it matters →

Not on the box. What your people actually wear, fitted the way they actually fit it, is the number that counts.

Peaks hide inside averages

Why it matters →

Impulsive work — presses, drop tests, nail guns — needs its own peak reading or it disappears into the day’s figure entirely.

The same job reads differently in a different room

Why it matters →

Hard walls give it all straight back. Two identical machines, two sites, two different numbers.

Why one number hides it

The loudest hour is not the average hour

A daily average can sit comfortably under 85 dB(A) while a single hour of it runs far over. The plan has to deal with that hour — not the average that buries it.

It adds up

It is the total that adds up — and the peaks still count separately

Hearing damage is cumulative. Even levels that never sound alarming fill the day’s dose — and by mid-afternoon a normal shift has already gone past what is safe over eight hours. Sudden loud events (a press, a drop test, a nail gun) are assessed against their own separate peak limit, on top of this daily total — see how the action values work.

Same figure, different problem

Two machines, the same daily figure

Both average about 87 dB(A) over a shift — the same number on a report. They are not the same problem, and one figure will never show you why.

Quiet, then a hit. The peaks do the damage; the average barely moves.

The Care Plan

Four years, one fixed price

from £895+ VAT / year

Fixed for the full four years — no annual re-quote, no uplift when we come back — with 25% off your first assessment when you sign up for the 4-year Care Plan.

  • Measured on site, by area and by role
  • Scheduled reviews that keep your assessment valid
  • Every assessment kept and reissued on request
The process

How the Care Plan works

Six steps, and only one of them needs anything from you.

1

You take the 60-second check, or call us

Four questions about what you run and how long for. It gives you a guide immediately, and it costs nothing. Prefer to talk? The number is at the foot of every page.

Only this step needs anything from you
2

We agree the price before anything happens

One fee for the whole four years, quoted up front — no annual re-quote, no uplift when we come back, and 25% off the first assessment. You know the total before you commit.

3

We measure your site as it normally runs

Nothing gets switched off or slowed for us. We measure by area and by role, so a grinder bay and a picking aisle are separate figures, not one average.

4

You get the assessment and a plan you can act on

Real exposure levels, where the action values are crossed, which zones need marking, what protection achieves at the ear, and what would bring the noise itself down.

5

We keep it current for four years

New machine, new line, new shift pattern, or just time passing — we re-measure and re-issue, rather than leaving you with a document that quietly stopped being true.

6

You always have the records

Every assessment and review kept and reissued on request — so when an auditor, insurer or customer asks, the answer takes a minute rather than a week.

Optional extra

See your own floor as a shape

Floor mapping turns your workplace into a landscape of noise — loud machines rise as peaks, quiet corners settle low and blue — so you can see at a glance where it needs work. A chargeable add-on from £495 + VAT.

Common questions

The things people ask first

How long does the assessment take on the day?

A typical small-to-mid site is measured within about 90 minutes. Larger multi-area sites take a half-day. We work around you, not the other way round.

Do we have to stop production?

No — and you shouldn’t. Measuring a quiet version of your floor gives a number that’s no use to anyone. We measure it running normally.

What happens if we buy a new machine?

Tell us and we re-measure the affected area and re-issue — it’s part of the four years, at no extra cost. Keeping the assessment true as the site changes is the whole point of the plan.

Is this a one-off survey?

No. It’s a measurement now, then the reviews, the re-measurements when your machinery changes, and the records you need if anyone ever asks — for four years, at a price fixed on day one.

Do you cover our area?

Yes — the whole of the UK, including multi-site groups. Our roots are on the south coast and we work nationwide. Where you are changes the travel, not whether we come.
