In my oppinion always grommit grip as well as needing some form of fire stop especially if the cables drop into any type of void, can you imagine how quick fire will travel through the cavity space and spread to any areas where the void encounters holes in joists, damaged plasterboard or other combustible spaces. For the sake of £2.50 a tube of Firecryl or fire mate intumescent sealer it's not worth even considering otherwise.
If struggling with gromit strip try edging strip but still use intumescent sealer.
then 6 months later try and get another RFC in there.
