Hi TS,

You have so many electricity guzzling device... esp the fridges, freezer and aircons.

Dump the multiple fridges and buy a single unit which should cut your energy consumption.

Set your aircon to cool at a slightly higher temp 28' should be cool enuff

You could call to or visit kedai TNB, have them check your meter or get it replaced.

Do you leave all your appliances and lights on even when no one is at home... or in the room?

Hard to tell since the TS only partially listed the electrical appliances in his house... TS didn't mention the lights, fans, spot lights or if he had a jacuzzi, koi pond or home theatre etc.

Or the complete household usage pattern.

For example houses lit up like a football stadium coz using several 200watt lights which consume alot of electricity or the entire household doesn't switch off the lights, fans or TV even when nobody is at home
