Canstar Blue rates customer satisfaction across a wide range of products and services, with the core purpose of helping consumers make better purchase decisions. The ratings are based on professional market research to determine the perceptions of consumers who have recently purchased and / or used the specific products and services. The independent results are freely available to consumers via our website.

None of our ratings constitute medical advice, and Canstar Blue is not making a recommendation or giving advice about medications or health related products. Always seek the advice of a doctor or pharmacist to find the right medication for you.   

We partner with respected professional market research agencies who undertake research on our behalf. We currently utilise Colmar Brunton, Australia’s largest independently owned Australian market research agency; I-view, an independent market research agency,  and Qualtrics a global enterprise research platform. All agents we employ are members of AMSRS, the peak body for Australia’s market and social research industry and work with panels that are ISO 26362 accredited.

In most categories, the sample is broadly representative of the Australian population in terms of gender, age and location, and is based on ABS Census data. Due to low incidence in other categories, the sample may be representative of those consumers who have had experience with the category researched. Only people who have used the specific product or service within a nominated time frame are able to answer the questions and be included in the survey results.

For example, only people who had purchased and consumed multivitamins in the last twelve months were included in the multivitamins results. The time frame specified for consumption or usage depends on the product or service category that is being researched.

In most categories, we receive survey responses from 3,000 people across a broad cross section of the Australian population for each category. We only include results from the respondents from this group who have used the product or service within the nominated time frame. In some low incidence categories, we receive survey responses from between 800 and 1,000 targeted consumers, who have had experience with the category researched.

The survey:

  • The surveys are delivered through the research companies’ online panels, as well as any external panels they may engage.
  • Colmar Brunton’s panel is ORU, which consists of more than 350,000+ consumers.
  • The I-view panel is around 125,000 active members.
  • Qualtrics utilise two ISO accredited panels Research Now and SSI
  • Respondents rate their satisfaction with the products or services at a brand level on a zero to ten scale, where zero is extremely dissatisfied and ten is extremely satisfied.

The ratings:

  • The criteria that are rated vary depending on the category.  They typically include overall satisfaction and value for money, while other criteria are included as appropriate to the research subject.  For example, customer satisfaction ratings for a retailer might include criteria such as service and range, while ratings for a refrigerator will include criteria such as reliability and quality.
  • The winner in each category is the one that receives the highest overall satisfaction rating once the scores from all respondents to the overall satisfaction question are combined and averaged.
  • Overall satisfaction is asked as a specific question. This means the overall satisfaction criteria represents an individual measure rather than a combined total of all criteria. As a result, some brands may find their overall satisfaction score is lower – or higher – than the scores they have received for other criteria.
  • When we cannot determine a clear winner from the criteria for the overall satisfaction rating, we will then look at the supporting criteria. The brand with the highest number of five star ratings within the supporting criteria will become the five star recipient in overall satisfaction, and thus win the award.
  • If a clear leader still cannot be determined from the supporting criteria, then joint winners will be declared.
  • For each criteria, any brand that receives 6 out of 10 or higher receives at least three stars and any brand that scores lower than 6 out of 10 receives one or two stars.
  • Rating results are comparative and the ratings table is first sorted by overall satisfaction star ratings results, and then by mean overall satisfaction score.

Note: Some past grids are sorted by star rating and then alphabetically.  Please refer to the the ‘Important Notes’ disclaimer at the foot of the grid for sort type

Canstar Blue is committed to making our customer satisfaction ratings freely available to consumers via our website. The business is privately owned by shareholders and continues to invest heavily in professional market research, so there are three ways in which revenue is generated:

  • Sponsorship and referrals: Canstar Blue may earn a fee for referrals from its website tables, and from sponsorship of certain products.  Fees payable by product providers for referrals and sponsorship may vary between providers, website position, and revenue model.  Sponsorship fees may be higher than referral fees. On our ratings results, comparison tables and some other advertising, we may provide links to third party sites. The primary purpose of these links is to help consumers continue their shopping journey from the ‘research’ phase to the ‘purchasing’ phase. If customers purchase something after clicking a certain link, we may be paid a commission or fee by the referral partner. Where products are displayed in a table, the display order is not influenced by commercial arrangements and the display sort order is disclosed at the top of the table, with the exception of Sponsored products (see below). Consumers can change the sort order to suit their preferences.
    • Sponsored products are clearly disclosed as such on website pages. They may appear in a number of areas of the website such as in comparison tables, on hub pages and in articles. Sponsored products may be displayed in a fixed position in a table, regardless of the product’s rating, price or other attributes. The table position of the Sponsored product does not indicate any ranking or rating by Canstar.  The table position of a Sponsored product does not change when a consumer changes the sort order of the table.
  • Ratings licenses:  Once category winners have been determined, the winning brands may have the opportunity to license the award for use in their marketing for a negotiated fee (however there is no requirement to do so). Each category is run approximately every 12 months. The market research remains independent and undertaken by a 3rd parties.
  • Online advertising:  Canstar Blue allows limited advertising on the website. Our primary intention is to present quality advertising that is highly relevant to consumers. We always include an ‘advertising’ or ‘sponsored link’ sign above the ad so people know exactly what it is.

Brands must receive a minimum of 30 responses to be included in the ratings. The market research is designed to pick up as many brands per category as relevant. However, some brands may miss out due to low sample size – for example small local or niche brands where their market share is currently low. A rated brand may also receive a ‘N/A’ (Not Applicable) rating for one or more criteria if it does not receive the minimum number of responses for that criteria.

Our published customer satisfaction ratings are the user friendly summary of the market research we conduct through Colmar Brunton. This research is 100% funded by Canstar Blue and valuable to us as we use the findings to generate ratings and in many other areas of the business.

The full research report is not available for sale.

We offer an amended research report for purchase to companies interested in learning more about our findings. Please note that this report does not include the raw data collected in our initial research. To find out more, contact our team at

The brands that feature in our ratings are those that have been nominated by respondents in the market research, and which have received a minimum of 30 responses.  We do not choose which brands to include.

Canstar Blue only publishes state ratings for categories which we are able to get a robust sample size at a state level. This is often difficult, due to different providers in different markets and varying population levels.

We have a Facebook page and a Twitter account that are updated regularly. You can also subscribe to our monthly newsletter to be kept up to date on our latest releases and articles. You can sign up to the newsletter following the link.

In addition to our consumer ratings, Canstar Blue collects data from energy, phone and internet providers in order to show price comparison tables for relevant products. Users can list products in order of price and several other variables, including Canstar Blue’s unique ‘Value rank’. The Value score is a rating (out of 10) and is a combination of the Price score and Feature score, which is determined by multiple factors relating to the provider and plan in question, including customer service & support, billing and payment options, and plan flexibility. The full details of our value rank methodology can be found via the following links:

In addition to our consumer ratings, Canstar Blue may also publish expert awards for electricity, phone and NBN providers. To do this, we use a sophisticated rating methodology, which compares providers’ suite of products offered to new customers. The ‘Provider of the Year’ award winners are determined by the cumulative performance of each provider across a range of consumer profiles within each category considered, over a period of 6 months. The awards consider a provider’s best performing product within each consumer profile, and considers the plan’s value proposition relative to the market based on Canstar Blue’s Value Rank for electricity, mobile or NBN respectively.
