Outside a fire door, to the side of a building, he have a light which is on 24/7. The internal route leading to the fire door is illuminate and with emergency lighting. I know that in the HM Government publication “Fire Safety Risk Assessment: Offices and Shops” (May 2006): “The primary purpose of emergency escape lighting is to illuminate escape routes but it also illuminates other safety equipment”. So it makes prefect sense for the external route to have lighting. But externally surely this would only make sense at times when it need to be illuminated (i.e. when it is dark) and when the building is occupied, rather than 24/7? I'm not even sure if I'm posing a question. Rather I am amazed that even with the premises officer we can't find a switch for this light. It appears to be on a circuit of it's own. B

Hi Chris, Was thinking along similair line. Looking at http://www.ukpower.co.uk...nning_costs_electricity/ it would suggest a min of around £80 pa just to run that one light. B

I'm a little confused, OP, do you just have an emergency light that is always on? Or a normal light (which is always on) with the addition of an emergency light back up (and if so is this emergency light on all the time as well)? If it's the former of the above, can't you just change the EL fitting to a non-maintained EL, therefore only activating during power failure? If it's the latter can you not rewire the normal everyday light (and install a light sensor) separate to the EL (and spec a non-maintained light). That would then give you everyday coverage during night time and the EL back-up should there be power failure.

It's a normal external light on a fire route. B
