Who should I contact if there is something wrong with my electricity supply? Leona October 08, 2018 10:05 Follow Do contact SP Electricity Service Centre a-zap at 1800 778 8888 (24-hour hotline). Related articles I suspect my electricity meter is faulty. What should I do? Can I use U-Save if I sign up for a contract through Electrify.SG? Oh no, I’ve entered the wrong information for the contract, can I edit these details? I’d like to terminate my plan. How can I do so? Why is there such a big difference in prices between the retailers? Are there any hidden costs not factored in? Comments 0 comments Please sign in to leave a comment.
