    Emergency light checks - Essential work?

    I have cancelled all my jobs, but I conduct monthly light checks on blocks of flats, so I am planning on still doing them because I don't have to be inside peoples homes or near them (at least 2 metre separation). Would others also consider emergency light checks to be essential works?

    Annual emergency light test

    I replaced the emergency lights in a small block of flats about 6 months ago, but the last time I did a 3 hour emergency light test was a year ago. Common sense says that I don't need to test the new emergency lights until they are a year old, but any clarification appreciated?

    Emergency Lighting query

    It's been a while since I tested emergency lights and I just wanted to clarify something. If the lights not working and the green LED light is off, is this an inverter and if the LED light is off and the lights still not working is this a dead battery?
