Fire proofing cable penetrations.

[Russell griffiths]

Morning. 
attatched garage 

I have 4 x25mm holes between the house and the attached garage, each hole has a 25mm conduit in it with a couple of cables in each. 
what are the regs for any fire prevention measures between the garage and the house, around the area of these cables. 

any thoughts. 
cheers.

Dunno if this applies for you: Scottish building standards technical handbook section 2.1.14 allows penetrations of up to 40mm diameter without remedial measures.

I'd just fill them with intumescent mastic.

That would be handy.
