Why is my power bill so high?

If you see that your power bill is above average, and you want to change that, the best question to ask yourself is “why is my power bill so high?” 

There are many factors that can affect the cost of your power bill each month, from efficiency of use, how many people you have living at your home and your rates. 

Lack of efficient power usage essentially means that you are not using your power in the smartest way. From leaving lights on in rooms that you aren’t using to leaving heaters and heat pumps on overnight, it can be considered wasted electricity.

Using your appliances efficiently means calculating when to use certain things and when not to. For example, instead of keeping the heat pump on the entire night, turn it off after an hour or so and close all the doors in that room so the heat will stay trapped there for a few hours, and then you can turn it back on if need be. 

Apart from not using your appliances efficiently, there are other factors that could be causing your power bill to be higher than another person’s, such as the number of people living in your home.

Whether you’re flatting, or you have a large family, this is something you can’t change, and by rule of thumb, the more people you have living with you, the higher the power usage will be.

Even though this is something you can’t really change, you can make sure each of your family members are using the household appliances as efficiently as possible and if you’re renting, you can make sure that each flatmate is paying their fair share of the power bill.

How to reduce my power bill 

Once you’ve figured out what’s causing your power bill to be so high, you can start making a change, starting with your power consumption.

Starting with air conditioning and heating, you can make a few changes to your usage with these two things and save tonnes of money each month. Air conditioning during the summer and using heating in the winter can account for a lot of the power bill, which is why it’s important to use these as efficiently as possible.

First of all, when using things like heaters and heat pumps, you should close all the doors in the room you’re using the heating in, to trap the heat. This way, not only will you be warmer, but you can also turn off the heating early and have the room stay warm. 

If you’re someone who can never be bothered with washing your clothes and always resort to using the dryer, you should reconsider this method. Dryers can be really expensive to use, and while using them once in every while is fine, using them on a weekly basis can help add to the power bill.

While it can be hard to dry your washing during winter, you should still look to use the outside washing line when you can. Check the weather forecast and see which days of the week have good weather and hang up your clothes on that day. You can also use inside clothes horses to dry your clothes inside on rainy days. 

Leaving your appliances on standby may just be a habit that you’ve gotten into that you may think doesn’t have too much of an effect on your power bill, but in reality, it does.

Leaving these appliances on standby can add over $100 on your power bill a year, and these appliances tend to be the entertainment devices such as the TV, gaming consoles and computer equipment.

One simple way to turn these off without using too much effort is to plug all of these into one multi-plug so that when you turn off the multi-plug, you’ll be turning all of the appliances off at once. 

The amount of water you use can also have a toll on your power bill too, as heated water can be extremely expensive. This is especially the case in Auckland, as according to Newshub’s article, the average cost of water in Auckland is increasing.

Watercare has said that they expect the price of water to increase by an extra $2.30 per month for an average household of 3 people. You can start reducing your water bill by taking short showers.

While it may be tempting to take longer showers in winter since it’s so cold, every minute costs more compared to other seasons because you’re more likely to use a hotter temperature.

If you and everyone in your family limit their showers to just 5 minutes a day, you could save 66% on your hot water bills for showers, compared to a 15-minute shower!

I found Glimp when I was looking for Internet Providers that I would have to sit through and compare myself. I at first thought Glimp was an Internet provider but then I was pleasantly surprised when they came up as a website solely for comparing all sorts of different things so the customer could find the best deal. I found my new Internet provider on there and even found out I could be with a better Power company then the one I am with now. Very Useful and I recommend Glimp to the bargain hunters!
