Maintenance & systems
LEV rarely gets its own line in the maintenance budget, and that is exactly why it fails. Extraction wears like any other plant, and when its upkeep is unplanned it competes with everything else for attention and loses - until a failed test or an enforcement notice turns a small planned cost into a large unplanned one.
The short answer
LEV rarely gets its own line in the maintenance budget, and that is exactly why it fails. Extraction wears like any other plant, and when its upkeep is unplanned it competes with everything else for attention and loses - until a failed test or an enforcement notice turns a small planned cost into a large unplanned one.
The detail
LEV is plant, and plant wears. Fans lose balance, belts slip, bearings age, filters load, ductwork gathers deposit and hoods get knocked - all of it gradual, all of it certain. Yet extraction is often left out of the planned maintenance budget, treated as a fixed asset that will simply keep running, when in reality it is a working system that degrades unless it is actively maintained. Giving it no budget line does not make it free; it makes its decline invisible until it fails.
A planned line covers the predictable parts. The statutory thorough examination falls due at least every fourteen months and can be scheduled and costed well ahead. Periodic servicing - filter changes as loading demands, belt tensioning, bearing checks, damper balancing - happens on a known rhythm rather than only after a breakdown. And a sensible line carries a margin for the repairs that wear inevitably produces, so a filter or a belt is a budgeted event, not an emergency.
Budgeted this way, LEV becomes a modest, predictable annual figure. Left unplanned, the same costs still arrive - but as reactive spending: an urgent repair to a system that has already failed a test, a rushed retest, downtime while a line is stopped, and the scramble of dealing with it all against a deadline. Reactive maintenance is almost always dearer than planned, because emergencies carry a premium and failures cascade.
The largest costs, though, are the ones a budget line prevents. A neglected system that fails a test, triggers an enforcement notice, or contributes to an occupational disease claim generates costs of an entirely different order - cost recovery, remediation, lost production, and potentially compensation. Against those, a planned maintenance line is not an expense so much as cheap insurance against far larger, unplanned ones.
What it means for you
The move is simply to give LEV the same treatment as any other critical plant: a named line in the planned maintenance budget, covering the tests, the servicing and a repair margin, set against the fourteen-month cycle. Once it is in the plan, it stops competing for scraps of attention and starts being maintained on schedule, which is what keeps it in control and out of the reactive-spending trap.
It also makes the cost knowable, which is what most businesses actually want. A predictable annual figure - the tests, planned servicing and a margin - can be set once and reviewed each year, turning LEV from an occasional nasty surprise into a routine line that behaves like the rest of the maintenance budget. Predictability, not just total cost, is the prize.
Seen properly, planning LEV maintenance is the cheapest way to run it. The system stays in control between examinations, the tests confirm rather than condemn, repairs are small and scheduled, and the large costs of failure, enforcement and claims are held off. The alternative - leaving it unbudgeted until it breaks - pays more, less predictably, for worse protection.

Questions
Because it is plant that wears - fans, belts, bearings, filters and hoods all degrade. Left out of the budget, its decline is invisible until it fails, which turns a small planned cost into a large unplanned one.
The statutory thorough examination every fourteen months, periodic servicing such as filter changes and belt tensioning, and a margin for the repairs that wear inevitably produces.
Almost always. Reactive spending carries an emergency premium - urgent repairs, rushed retests and downtime - and failures cascade. Planned upkeep spreads smaller, predictable costs over the year.
The costs of failure: a failed test, an enforcement notice with cost recovery, lost production, and potentially an occupational disease claim. These dwarf the planned line that would have prevented them.
Yes. A named annual line covering tests, servicing and a repair margin can be set once and reviewed each year, turning LEV from an occasional surprise into a routine, knowable figure.
