Buy an LEV thorough examination on comparable terms
Use one system schedule, ask every examiner the same competence questions and compare the full TExT deliverable—not merely a certificate or day rate.
A comparable quote must answer five things
- Who will examine each system and what comparable LEV experience can they evidence?
- Which fans, hoods, test points and operating conditions are included?
- How will missing commissioning or benchmark information be handled?
- What measurements, control judgement, report and defect priorities will be delivered?
- What servicing, repairs, retesting, access, travel and VAT are excluded?
Information to assemble before requesting quotes
Mark unknown items explicitly. Discovery can be priced; hidden assumptions cannot be compared.
- Site address, access arrangements, shifts and shutdown constraints
- LEV system list with fan/system identifiers and every connected hood or extraction point
- Process and contaminant controlled by each system
- Commissioning report, design performance, diagrams and user manual where available
- Previous TExT reports, measurements, due dates and unresolved actions
- LEV logbook, routine check, service, filter and repair records
- Recirculation, air-cleaning, discharge, make-up-air and access details
- Desired visit and report dates

Competence and evidence questions
Competence is specific to the equipment, system and judgement being bought. Ask about the proposed person, not only the company.
- Who is the named examiner and what current LEV examination training and experience can they evidence?
- Which comparable systems and contaminants has that person examined?
- Which calibrated instruments and test methods will be used?
- How will the examiner establish performance where commissioning data is missing?
- Can you provide a redacted comparable report showing measurements, judgement and prioritised actions?
- How are examination conclusions separated from repair or product sales?
- What professional indemnity and public liability evidence applies?

Do not add the scores blindly. Missing competence, equipment scope or statutory reporting can be a stop condition rather than a small disadvantage.
Report acceptance check
- Correct site, process, contaminant and complete system identity
- Every hood and measurement point is traceable
- Operating conditions and instruments are recorded
- Measured values are compared with intended or justified performance
- Physical condition and control effectiveness are judged separately
- Defects and actions are specific, prioritised and understandable
- Missing baseline data and limitations remain visible
- Next TExT date and any shorter interval are explicit
