You must have your emergency lighting tested every month, in accordance with BS EN 50172:2004 / BS 5266-8:2004. The requirement for this monthly testing is a simple period of simulated failure, during which period all luminaires and signs can be checked to make sure that they are present, clean and functioning.
A longer test should then be carried out annually, to ensure that the emergency lighting has been correctly maintained with all components functioning correctly. It is vital that records of all tests are kept, as in the unfortunate event of an emergency, you will be required to produce evidence of your compliance in accordance with the law.
