Choosing the best bottled gas supplier

Value is always a key consideration for the consumers in our ratings, across all our awards. And when it comes to bottled gas customers, it's no different.

Nearly half (41%) of those in our survey cite Value for Money as their No.1 concern when rating their choice of bottled gas supplier.

And if you rely on bottled gas to heat and power your home, it's essential that your supplier is reliable – delivering on time, every time.

Therefore it's no surprise to discover that Customer Service is also important to our gas customers, cited as the key driver of satisfaction by almost a third (29%) of respondents.

Here's the full rundown of what the consumers in our survey say are the main things they consider when rating their bottled gas suppliers:

  • Value for Money: 42%
  • Customer Service: 29%
  • Bill & Cost Clarity: 20%
  • Focus on Sustainability: 9%

FAQs about Canstar's Bottled Gas Award

Canstar's Most Satisfied Customers Awards recognise companies with the most satisfied customers, based on consumer surveys involving thousands of everyday Kiwis.

Canstar surveyed 405 Kiwis who have a bottled gas account and asked for their feedback on their gas supplier.

  • The outcomes reported in these ratings are measured via Pureprofile's accredited online research panel.

Respondents rate their satisfaction with their bottled gas suppliers from zero to ten, where zero is extremely dissatisfied and ten is
extremely satisfied. Brand satisfaction was rated by respondents on the
following criteria:

  • Bill & cost clarity: the billing provides accurate details of gas usage and associated costs.
  • Focus on environmental sustainability: does the retailer offer clear guidance on its green credentials.
  • Customer service: the customer service provided by the bottled gas retailer is helpful, prompt and of a high standard.
  • Value for money: the bottled gas supplier offers great value for money when comparing service, product and price.

The winner is the brand Kiwis rate highest for the things that matter most to customers, based on overall satisfaction. To see how we crunch the numbers, check out our methodology.
