hi guys..need some advices here..

my housing developer suggest me to upgrade my current house unit..to add a submain cable (from front) to my backyard for extra power i might need for future gardening /landscape design..they are charging rm400 for this..is it expensive?

very depends on the job scope, how long the distance from front to backyard, however you can always get few more ppl quote so that you can compare, make sure using good quality cable (amad cable for outdoor)
