LEV testing - budgeting
A single busy site can have dozens of extraction points across its machines and benches - and because LEV testing is priced by the point, budgeting for it means counting them, not guessing at a round number.
The short answer
On a single site with many machines, LEV testing cost is driven mainly by the number of extraction points - each hood, booth, arm and capture point is examined individually. So budgeting starts with counting them accurately. Testing the whole site together in one visit is more efficient and cheaper per point than piecemeal, and the budget should also allow for the remedial work a first thorough test often finds.
The cost driver
On a busy site the instinct is to think of LEV testing as a single site cost, but it is really the sum of many individual examinations. Each extraction point - every machine hood, fume arm, booth, downdraught bench and capture point - has to be assessed and measured on its own, so the cost is driven by how many points there are, not by the floor area of the site. Two sites of similar size can have very different point counts and very different costs.
This is why budgeting starts with counting. A site's LEV bill is built up from its capture points, so knowing how many you actually have - which is often more than a quick look suggests, once every arm, bench and machine extraction is counted - is the foundation of a realistic budget. Guessing at a round number without counting the points is how budgets end up wrong.
Count everything
The point count on a busy site is easy to underestimate, because it is not just the obvious hoods. It includes on-tool extraction arms at benches, downdraught tables, capture points on individual machines, booths, and any other position where contaminant is drawn off at source. A workshop that seems to have a handful of extraction points can, counted properly, have many more once every capture position is included.
So an accurate count is worth doing carefully. Undercounting leads to a budget and a quote that both change once the real number emerges; a full count of every capture point across every machine and bench gives a figure you can actually plan to. It also ensures nothing is missed in the testing itself, since a point not counted is a point not tested - a compliance gap as well as a budgeting error.
Test it together
For a single site, testing all the extraction points together in one visit is more efficient than testing them piecemeal. Doing them together shares the setup, travel and reporting across the whole site, keeps all the records aligned to a single date, and means nothing gets forgotten between separate visits. So while the total reflects the number of points, the per-point cost tends to be lower when the whole site is tested as one exercise.
It also suits the compliance rhythm. Because the site's LEV largely falls due together on the same cycle, testing it in one coordinated visit keeps the whole site on schedule and the evidence in one place - which is both cheaper and cleaner than a scatter of separate tests at different times. Budgeting for a single whole-site test, rather than ad-hoc individual ones, is usually the better economics.
Allow for remedials
A realistic LEV budget for a busy site includes more than the examination itself. A thorough test, especially a first one or one after changes, commonly finds remedial work needed - a point under-performing, a filter spent, a section of ductwork to seal - and putting those right is a separate cost from the test. Budgeting only for the examination and being surprised by the actions is a common mistake.
So the sensible approach is to budget the examination as a predictable, recurring cost based on the point count, and to allow a provision for remedial work on top, particularly on a site being properly tested for the first time. That way a list of actions is expected and can be dealt with promptly, rather than becoming an unwelcome shock - and the site moves towards a state where future tests find less to fix.
The takeaway
Budgeting for LEV testing on a site with many machines comes down to a few disciplines: count the extraction points accurately, because that is what drives the cost; test the whole site together for the better per-point economics and cleaner compliance; and allow a provision for the remedial work a proper test is likely to find. Together these turn LEV testing from an uncertain lump into a plannable, predictable cost.
Done that way, a busy site can budget its LEV testing with confidence rather than guessing - knowing roughly what the examination will cost from the point count, keeping it efficient by testing together, and being ready for the actions. That is how a site with many machines keeps its extraction tested and compliant without the cost being a surprise each time.
Questions
Mainly by the number of extraction points - each hood, booth, arm and capture point is examined individually. So the cost is driven by the point count, not the floor area, and budgeting starts with counting them accurately.
Because the count drives the cost and is easy to underestimate - it includes on-tool arms, downdraught benches, booths and machine points, not just the obvious hoods. Undercounting makes the budget and quote wrong, and a point not counted is a point not tested.
Usually yes. Testing all the points together in one visit shares setup, travel and reporting across the site and keeps records aligned to one date, so the per-point cost tends to be lower than piecemeal testing.
Yes. A thorough test - especially a first one - commonly finds remedial work needed, which is a separate cost from the examination. Allow a provision for it so a list of actions is expected rather than a surprise.
Count the points to estimate the examination cost, plan a single coordinated whole-site test, and allow a provision for remedials. That turns LEV testing from an uncertain lump into a plannable, recurring cost.
Because a point that is not counted is a point that is not tested - a compliance gap as well as a budgeting error. A full count of every capture position ensures nothing is missed in the testing itself.
