LEV testing - a lapsed test
It is easy to treat a lapsed LEV test as a missed diary date - something to catch up on when there is time. But letting the test lapse does two things at once, and neither is trivial: it puts you out of compliance with a legal duty, and it leaves you with no current evidence the system is actually controlling exposure. The date is the least of it.
The short answer
Letting an LEV test lapse has two consequences at once. First, it is a compliance breach: LEV controlling a health hazard must be thoroughly examined and tested at least every fourteen months, so once that interval passes without a test, the legal duty is not being met. Second, and just as important, a lapsed test means there is no current evidence the system is controlling exposure - the last valid confirmation has expired, so you no longer know the LEV is working. A lapsed test is therefore not just a missed date; it is a gap in both your compliance and your knowledge that workers are being protected.
Not just a missed date
The instinct is to see a lapsed LEV test the way you would see any overdue task - a date that has slipped, to be caught up when convenient. That framing understates it, because a lapsed test is not one problem but two. The moment the examination interval passes without a test, you are both out of compliance with a legal requirement and without any current evidence that the extraction is actually working. Those are two distinct consequences, and each matters on its own.
Understanding this is what separates treating the lapse seriously from treating it as an admin slip. A missed date sounds minor; a compliance breach combined with a loss of assurance that a health control is working is not. The point of the fourteen-month cycle is to keep both the compliance and the evidence continuously current - so when the test lapses, both lapse together. That is why a lapsed LEV test warrants prompt action rather than being parked: the two things it costs you are exactly the two things the test exists to provide.
The compliance consequence
The first consequence is a compliance breach. LEV that controls exposure to a substance hazardous to health must be thoroughly examined and tested by a competent person at least every fourteen months - this is a legal requirement under the control-of-substances duties, not a recommendation. So once the fourteen months since the last test have passed without a new one, that duty is simply not being met. The system is operating outside the required examination regime, and the business is in breach of a specific, dated legal obligation.
This has practical weight. If an inspector reviews the site, an overdue examination is a clear, documented failing - the dates speak for themselves, and there is no room to argue a system tested fifteen or eighteen months ago is within a fourteen-month cycle. It can also matter to insurance and to any occupational health claim, where being outside the required testing regime at the relevant time undermines the position that the hazard was being properly controlled. The compliance breach is not abstract: it is a concrete, evidenced gap that others can see and act on, and it persists for as long as the test remains overdue.
The evidence consequence
The second consequence is quieter but just as serious: a lapsed test means you no longer have current evidence that the LEV is controlling exposure. A thorough examination is the measured confirmation that the system is working - the airflow and capture velocity checked against what the process needs. That confirmation is valid for the examination interval; once the interval passes, it has expired, and with it your current knowledge that the system is actually protecting people. You are relying on an assurance that is out of date.
This matters because LEV can decline invisibly. A fan can lose performance, a filter can load, a duct can leak - all without the system looking any different. The periodic test is what catches that decline, so a system that is overdue for testing is one whose performance has not been confirmed for longer than it should have been, during exactly the period when it could have quietly fallen below what is needed. So the lapse is not just a paperwork gap - it is a real gap in knowing whether the control is working, at a time when it might not be. The longer the test is overdue, the longer that uncertainty runs.
Putting it right
The good news is that both consequences are fixed by the same action: getting the thorough examination done. Once the test is carried out, compliance with the examination duty is restored - the system is back within the required regime - and current evidence that the LEV is controlling exposure is re-established, or, if the test finds a problem, the problem is identified so it can be put right. So the response to a lapsed test is straightforward: arrange the examination and close both gaps together, rather than leaving them open.
What matters is not treating the lapse as low-priority because it presents as a missed date. The framing to hold onto is that an overdue test means both a live compliance breach and an absence of current assurance that a health control is working - two real problems running concurrently for as long as the test stays overdue. Seen that way, catching up the test is not administrative tidying but closing a genuine gap in both legal standing and worker protection. And keeping the test on its cycle in future avoids the lapse arising at all, which is why the examination date is worth tracking as a firm deadline rather than a flexible target.
The takeaway
A lapsed LEV test is not just a missed diary date. Letting it lapse does two things at once: it puts you in breach of the legal duty to have LEV thoroughly examined and tested at least every fourteen months, and it leaves you without current evidence that the system is actually controlling exposure. Both are real, both persist for as long as the test stays overdue, and both are exactly what the examination cycle exists to keep current.
So the honest way to see a lapse is as a concurrent gap in compliance and in assurance - a documented legal failing and an absence of confirmation that a health control is working, at a time when it might quietly have declined. Both are closed by the same action: getting the examination done. That restores compliance and re-establishes the evidence together. Treating the test date as a firm deadline rather than a flexible one keeps both continuously current - which is the point of the cycle in the first place.
Questions
Two things at once. You breach the legal duty to have LEV controlling a health hazard thoroughly examined and tested at least every fourteen months, and you lose any current evidence the system is actually controlling exposure. A lapsed test is a gap in both compliance and assurance, not just a missed date.
Yes. The examination at least every fourteen months is a legal requirement under the control-of-substances duties, not a recommendation. Once that interval passes without a test, the duty is not being met and the business is in breach of a specific, dated obligation - a clear, documented failing an inspector can see.
Because a thorough examination is the measured confirmation the LEV is controlling exposure, and it is valid only for the examination interval. Once the interval passes, that confirmation has expired, so you no longer have current proof the system is working - you are relying on an out-of-date assurance.
Yes, because LEV can decline invisibly - a fan losing performance, a filter loading, a duct leaking, all without looking different. The periodic test is what catches that. An overdue test means the performance has not been confirmed during exactly the period it could have quietly fallen below what is needed.
It can. Being outside the required testing regime at the relevant time undermines the position that the hazard was being properly controlled, which can matter to insurance and to any occupational health claim. The overdue dates are documented and speak for themselves.
Get the thorough examination done. That single action closes both gaps: it restores compliance with the examination duty and re-establishes current evidence the LEV is controlling exposure - or identifies a problem so it can be fixed. Keeping the test on its cycle in future avoids the lapse arising at all.
If your LEV test has lapsed, our thorough examination closes both gaps at once - restoring compliance with the examination duty and re-establishing current evidence that your system is controlling exposure.
