Can i run cable behind plaster board, it's a feed to outside light, I had run it in a plastic chanel but I've now taken all the plaster off, can I clip it direct to brick and then dot n dab board over it?

if your real fussy u can put plastic capping over it but its not a regulation . hope your going to tidy that mess up . also any cables buried in walls less than 25mm must be rcd protected and in safe zones
