Holes in ceiling

JDW

The property I’m working on have some holes in the ceiling where wiring comes though straight into plastic trunking (the lights have been moved at some time).

Are holes allowed like this or do they need something over them?

I was going to put a square pattress box over the holes, is this acceptable or even needed?

    Generally, most ceilings will be expected to have some kind of fire protection, not just those forming a fire compartment (plus requirements for noise and possibly draughts) - but some research a while ago suggested that a few 50mm holes in a conventional ceiling (with solid timber joists) made little difference to its fire performance.

    If the holes are small (cable sized - 20 or 30mm say) and covered by the trunking then I'd not worry. If the holes are still exposed, I'd favour filling them with some plaster-like material. If the holes are large in a plasterboard ceiling , I tend to use off-cuts of plasterboard - glue one strip behind, and then glue a hole shaped bit onto that to mostly fill the hole and give a surface flush with the original plasterboard - a bit of fine filler can then make a practically invisible repair once painted.

    50mm holes may have little effect on fire performance, but it's more often smoke that's the killer. Fire compartments have to be sealed against the passage of smoke as well as flames.
