Emergency lighting installation in London

What the design covers

• Escape routes: corridors and routes to every final exit, lit along their length.
• Points of emphasis: each exit door, every flight of stairs, changes of level and direction, and corridor junctions.
• Safety equipment: fire alarm call points and firefighting equipment, so they can be found in the dark.
• Open areas: larger rooms where people would otherwise be left in darkness before they reach a route.
• Exit signs: the signs that must stay visible on mains failure, lit or illuminated.
• Outside the final exit: enough light to move away from the building safely.

New fit-out, replacement or extension

On a fit-out we work from the layout drawings and the fire strategy, so the lighting goes in with the ceilings rather than after them. On an older building the question is often replacement: fittings whose batteries no longer hold three hours, and a layout that no longer matches the rooms. Where the existing system is sound we extend it rather than start again, and say so in the quote.

After the installation

BS 5266-1 expects a short monthly function test and a full-duration test every year, recorded in the log book. Since the 2025 edition there is also a photometric verification at least every five years, a measured check that light levels still match the design. Our guide to how often emergency lighting must be tested covers all three, and emergency lighting testing is the service that keeps the certificate current.
