Selectra’s Opinion on Slingshot

Slingshot is a broadband provider that now bundles power; bundling can produce savings if you want both services together and appreciate a single bill. Bundles are convenient and can be competitively priced, but always compare standalone power rates and bundle penalties or price rises after promotional periods before you commit. 

Understanding Online Reviews

Review sites like Trustpilot can provide useful insights, but they are often dominated by customers who had a negative experience. As a result, the overall rating may not accurately reflect the typical experience for most customers, but rather the opinions of a vocal minority. For the most accurate picture, it’s best to consider both positive and negative reviews together.

What Do Customers Say About Slingshot on Trustpilot?

Customer review platforms such as Trustpilot give a genuine view of how people feel about their energy provider. They highlight real experiences shared by customers, offering a useful snapshot of overall satisfaction.

Reviews can reveal honest feedback about customer service, billing accuracy, reliability, and how well a company resolves complaints.

By comparing ratings across platforms, consumers can get a clearer and more balanced understanding of Slingshot’s reputation and whether it aligns with what the company promises.

How Do I Switch to Slingshot?

With many electricity providers operating across New Zealand, switching to Slingshot — or any other power company — is a simple process that can help you find a better deal or improve your service experience. Whether you’re after lower rates, renewable options, or better customer support, the steps are straightforward.

Here’s how to make the switch:

  1. Gather Your Information: Find a recent electricity bill to note your ICP number (Installation Control Point) and your average energy usage. This information ensures accurate plan comparisons.
  2. Compare Plans and Rates: Review electricity plans from Slingshot and other New Zealand providers. Check daily charges, unit rates (¢/kWh), contract lengths, and any exit fees to see which option fits your household best.
  3. Start Your Switch: Once you’ve found the right plan, begin your switch on Slingshot’s website or by calling their customer service team. They’ll handle all contact with your previous provider.
  4. Provide a Final Meter Reading: On or before your switch date, submit your meter reading to finalise the transfer. This ensures an accurate final bill from your old provider.

Switching electricity providers in New Zealand is quick, easy, and seamless — your power supply won’t be interrupted during the process.
