It is a legal requirement that all commercial and industrial premises have to have a safe exit for anyone that is in the building with exits being well lit and clearly marked.
It is recommended that you have a monthly flick test done to check which lights are working to enable any that are to be replaced. It is compulsory that a full shut down is performed at least once a year and in more vulnerable premises such as residential homes to have a 6 monthly full discharge check.
On our standard monthly plan we would operate monthly flick tests with 1 x full shut down check, this is then recorded and sent to you via email detailing any failures with costings to rectify. These reports are acceptable to insurance companies as proof of health and safety being adhered to within a commercial setting.
