Our Home Electrical Services

Whether you’re in a new home, renovating or have been in your home for many years, having a local Castle Hill electrician oversee your electrical needs can prove to be a valuable asset.

Some of the most common reasons to have an electrician out to your home are for general home installations and maintenance items such as:

  • Switchboard installations
  • Rewiring of lighting and power circuits
  • Data cabling
  • Electrical design and installation
  • Energy-efficient lighting
  • Fire alarms and smoke detectors
  • Renovation electrical
  • Safety inspections
  • And more…

In Australia, there are very strict laws on what DIY electrical jobs can be done and what can’t. It’s a good idea to check with the regulations, so you don’t compromise on your safety, and your insurance should the job not go to plan.

How to consume less electricity in your home 

One of the biggest concerns for households is how to save on their energy bill. According to the Department of the Environment and Energy, household appliances in Australia account for about 30 per cent of the energy we use in our home, whereas lighting only accounts for about 12 per cent.

While switching off lights and electrical appliances when not at home will definitely save on your power bill, it’s more prevalent the more electrical appliances you have. Appliances that aren’t switched off will only account for about 3-10 per cent of your energy bill.

However, it does add up, and the bigger problem arising is as a household we are starting to have many more electrical devices in the home, so this will keep increasing. The average Australian home has 15 -17 internet-connected devices alone, and this is set to double by 2022.

Some quick tips to save on your electricity:

  • Switch off lights when not home
  • Switch off electrical appliances at wall
  • Only use standby mode where necessary
  • Replace light bulbs with energy-efficient lighting
  • Defrost meat in the fridge instead of the microwave
  • Use lids on pots and pans for quicker boiling
  • Don’t over use heating and air-conditioning

Top appliances that use the most energy in standby mode

Most people are unaware of just how much power can still be consumed when appliances are on standby mode.

According to the National Appliance and Equipment Energy Efficiency Committee, standby power consumption accounts for up to 10 per cent of household electricity usage and can generate more than 6.5 million tonnes of carbon dioxide emissions.

Not only is it bad for the environment, but most the time you don’t even need these appliances on.

Here’s a list of the top appliances that waste energy in standby mode.

  • Desktop computer: Computers can use up to 15 per cent of the total standby power use in your home.
  • Air-Conditioner: If you’re not using it, switch it off at the wall.
  • TV: Switching a TV off by the remote puts it in standby mode. Switching it off at the wall will conserve more energy.
  • Printers and scanners: They don’t get used often, so don’t keep them on at the wall.
  • Kettles and coffee machines: Often we only use these in the mornings or at night, so they don’t need to be on all day.
  • Mobile phone chargers – Unless in use, unplug and switch off at the wall.
  • Electric toothbrush charger, cordless electric shaver and dustbuster: Turn off the changer and only use when the appliance is running low on power.
  • Microwave – Unless in use, switch it off at the wall.
  • Washing machine and dishwashers: New electronic models continue to use power even when switched off.

Can I perform DIY electrical work in my Castle Hill home?

Almost all electrical work in Australia must be completed by a fully qualified and licensed electrician. For example, you cannot DIY replacing light switches, installing a new ceiling fan or replace a lead on an appliance. However, installing low voltage garden lighting, changing lightbulbs, and installing a battery-powered smoke alarm can be done yourself.

It’s important to remember that electrical work carries significant risk and when in doubt, it’s always best to call in a professional. At O’Brien Electrical Castle Hill, we’re always here to help, no matter the size of the job. Request a quote online or call us at (02) 9894 4843.
