My quick comparison:
- Lighting point: Mine RM55, Urs RM60
- Fan point: Mine RM68, Urs RM70
- 13A point: Mine RM105, Urs RM90
- Heater/oven point: Mine RM285, Urs RM220
- Phone point: Mine RM180, Urs RM100
- Install light/fan/heater: Mine RM20/45/80, Urs RM10/20/60

Prices are about similar for #1 to #3. I guess it's give & take. If not calculative, should be reasonable.

For heater/oven point, does yours come with a switch (those with small red LED)? If no, then maybe this is why yours cheaper by RM50.

Somehow I feel my phone point price is expensive, by 80%!

Your installation charges are cheaper. Anyway, I think I still can accept mine assuming the contractor keep to his promise of giving his quality finishing/work. From what I surveyed, RM80 for heater is kind of reasonable (with PVC case only, no conceal).

Now left the below items. I feel the prices are kind of high. Eg. Astro & Ethernet same price as heater point, RM285. I don't know if it's because of the cable that is expensive vs electric cable or I only install 1 or 2 points for each of them. Maybe electric sifus here can help to enlighten me.
