In short
Fire-rated downlights help maintain a ceiling's fire resistance where cut-outs would otherwise compromise it; requirements depend on the building and ceiling construction.

Cutting holes in a fire-rated ceiling can reduce its fire resistance. Fire-rated downlights are designed to restore that protection.
When they matter
Typically where a ceiling forms part of a fire-resisting element, such as between floors in residential or mixed-use buildings.
How they work
Fire-rated fittings use intumescent materials or protective housings that seal the opening in a fire.
In commercial buildings
Many commercial suspended ceilings are not fire-resisting elements, but always check with the fire strategy and building control.
What to ask
- Is the ceiling fire-rated, and for how long?
- Has the fitting been tested in a similar construction?
- Does it allow for insulation and acoustic requirements?

Do all downlights need to be fire-rated?
No. Fire-rated downlights are needed only where the ceiling is part of a fire-resisting construction. Check the fire strategy.
Who decides if fire-rated downlights are required?
The fire strategy and building control requirements for the project.
