hi all, I hope someone can enlighten me. thank for your help in advance. Now i am getting the resale flat and owner had renovated the house 5 years ago (main water paip , electrical wiring). I don't want to rewire whole house but just want to reshuffle + add some new electrical/aircon/heater point, is this possible? anyone can share your experience? (charges, how many days it take? any particular details to take note of? ) thank you so much.
