What Are Fire Rated Downlights?

The most common questions we get on downlights relate to the term “fire rated”. It’s a really important point, so here’s a simple explanation of what it means and how it applies.

What is a fire rated downlight?

In any building, a ceiling helps slow the spread of fire. The ceiling will have a fire rating depending on how well it slows the spread of fire. If you install a recessed downlight into a ceiling, chances are you are reducing that fire rating. The hole you cut for the fitting lets flames spread between floors more easily, often causing the ceiling to collapse within a few minutes instead of the usual half hour or more.

A fire rated downlight includes special materials that expand when heated and seal the cutout. This slows the fire long enough for anyone overhead to escape.

Does every downlight have to be fire rated?

Downlights should be fire rated to protect people on the floors above and aid evacuation. Slowing the spread of fire makes escape easier for all concerned and reduces risk of harm from falling debris.

You can use a standard downlight with a fire hood, but this often ends up being more expensive.

The Electrical Safety Council (ESC) recommends that fire rated options should be used in all buildings even though fire resistant downlights aren’t legally needed under a roof void (e.g. An empty loft).

What fire rating do I need?

The fire rating of a downlight has to match the fire rating of the ceiling, maintaining its minimum period of fire resistance. Luckily, most downlights are tested for up to 90 minutes of fire resistance, which is enough for most ceilings in most buildings.

Tables A1 and A2 of Part B Building Regulations volume 1 (dwellings) and volume 2 (commercial) provide specific info on this topic if you need it.
