Electrician Job - Fish Hoek, WC, 7975

Hi there, I have two needs - I need a gueyser timer procured and installed and I need an electrician to get to the bottom of why my flat is consuming so much electricity. I am a single person living in a fifty square meter flat. I vary rarely use heaters and have no washing machine or dryer or dish washer. I only really use geyser, stove, fridge and lights and yet my monthly bill is 1200. When I went away for a week recently I switched everything off other than my fridge and my weekly costs remained exactly the same. I suspect something is wrong. Could you give me a quote on what buying and installing a geyser timer would cost as well as diagnosing the source of why my flat is consuming so much electricity? Best
Emma.
