Cost & commercial
A single site running many machines does not have one LEV test - it has many, one for each system. Budgeting well is less about the price of a single examination and more about how you organise, group and time them across the year so the total stays predictable.
The short answer
A single site running many machines does not have one LEV test - it has many, one for each system. Budgeting well is less about the price of a single examination and more about how you organise, group and time them across the year so the total stays predictable.
The detail
Start with an inventory. List every LEV system on the site, and under each one every extraction point, because that is what sets the scale of the job and the annual figure. A site with a dozen machines may have far more points than a quick walk suggests, and it is those points, not the floor area, that the budget has to cover.
Then group the work. Bringing every system into one visit spreads a single attendance and travel charge across many examinations, which is almost always cheaper per system than booking them piecemeal. Where systems fall due at different times, it can be worth aligning their fourteen-month cycles so they can be tested together in future, turning several call-outs into one planned day.
Look at the commercial options as well. Many providers offer fixed multi-year plans or annual maintenance agreements that bundle the statutory examination with interim checks and hold the price steady, which makes the line easy to budget. Whatever the arrangement, keep a per-system logbook, since each system needs its own record of tests and repairs kept for at least five years.
Consider staffing and access when you plan the day. Testing around a working site means coordinating with production so machines can be reached and briefly paused in turn, and a large site is far easier to examine in one logical sweep than in scattered return visits. A provider who can walk the whole site in a single planned pass, rather than coming back for stragglers, keeps both the disruption and the repeated attendance charge down.
What it means for you
The examination fee is only half the budget. On a site with many machines, some systems will need remedial work - a filter, a repair, a rebalanced damper - and a sensible budget carries a margin for that rather than treating every pass as guaranteed. Planning for likely fixes is far cheaper than reacting to a failed system that has stopped protecting people.
Done this way, a large site becomes manageable: a known list of systems and points, one efficient visit, an aligned cycle, and a realistic figure that includes both the tests and the follow-up. That is a budget that holds, and a site that stays compliant without last-minute scrambles.
Keep an eye on the calendar as well. On a multi-system site it is easy for one unit to slip past its fourteen-month date while attention is on the others, and a lapsed system is both a compliance gap and, often, a rushed premium booking to catch up. A simple schedule that flags each system's due date well ahead turns the annual spend from a scramble into a routine, foreseeable line.

Questions
Inventory every system and point, group them into one visit, align the test cycles, and carry a margin for likely remedial work.
Usually yes, because a single attendance and travel charge is spread across many examinations instead of being repeated for each.
Often, by aligning the fourteen-month cycles so systems fall due together and can be examined in one planned visit.
They can steady the price and bundle interim checks with the statutory examination, which makes the annual budget easier to hold.
Yes. Each LEV system needs its own record of tests and repairs, kept for at least five years.
