So far tiling of the toilets and kitchen are done. Currently running wires and cables for the house. Electrical needs some planning especially for first time house owner. Numerous issues to consider and this will have a significant impact on the reno budget. Many failed to realize how costly electrical is and fail to cater a realistic budget for it. Number of lighting points - depends if you are doing false ceiling, cove lights. Normally false ceiling will come with down light. One plus point of false ceiling is that it can help to conceal aircon trunkings, wiring etc. Down light are costly, ranging from $20 or more, even more for LEDs. and each down light is consider as a lighting point. So add the cost up - eg. down light cost $30, lighting point $35, installing $10 = $75, imagine if you have 20 of these. Also have not add in the cost of the false ceiling. 13A Power Point - The price difference between one and double power point is a mere $10-$20, so most owners will go for double at a given point. Then it is the cost of a double point that is the killer. Prices ranges from $60 or more per double. So if you place gonna install 15 double point, you know your math. Data Point - Averages from $110 up. Average house need 4 points if doing structure cabling. TV Point - eg. $90 per point, if all rooms need one, mean times 3. Telephone Point - Also in the tens of dollars, can be $50 or more but may not be need in all rooms since most if not all uses HP. Unless fax is needed. Then the rest there are aircon point, 2 way switches, installation of fan, installation of lights, hood & hob point etc subject to needs and want. Some prefer different switches like Clipsal, Legrand, schneider etc and so the price snowball..... Time to bring out the calculator...... Remember, each lighting point is counted as one point. So if you choose a pendant light that needs 3 pcs of it to achieve that aesthetic look means you are paying 3 x lighting point and 3 x light installation. 2 way switches are a must in some houses due to layout. No one wants to off the living room light where the switch is near the main door and only to walk thru the darkness to the bed room. So beware and be prepare.
