What records do I need to keep from LEV testing?

The test report, which contains information on the system, test findings, any fixes or modifications, and whether the system passed or failed, must be preserved. Employers are required by UK legislation to retain LEV test results for a minimum of five years. It is also a good idea to document regular maintenance and inspections, such as duct cleaning or filter replacements, in between official testing.
Possessing these records demonstrates to inspectors or insurers your commitment to employee safety and compliance. If you need to keep track of when parts were last serviced or replaced, they are also a useful resource.
