Spark Energy

We created a review process which included: a code review, detailed bug fixing and the implementation of new features.

Spark Energy are the UK’s leading energy supplier for UK tenants. They pride themselves on providing a ‘refreshing alternative to the ‘Big Six’ with top customer service and innovative technology.

Improving Spark Energy’s app 

Spark Energy approached Red C unsatisfied with the performance of their current app developers. Spark Energy selected Red C to help review and improve the app’s user experience, on the basis of our technical expertise. The app was developed to enable Spark Energy customers to manage their accounts, on the go. Using the app, customers can view their balance, set up a direct debit, and submit meter readings.

The app provides Spark with a sweet spot. Spark customers can use the app to find the best tariff for them, without the hassle of lengthy phone calls with call centres. Spark Energy began with a soft launch for the app. During this period the app received no advertising, but was received well. The app received 1,200 downloads and 500 meter submissions were made from 300 customers.



After meeting with Spark to discuss the issues they were facing, Red C created a review process. This included:

  • Code review - which included refining the file structure to meet industry standards.
  • Detailed bug fixing - an in depth app testing period to identify bugs and problems, in order to create a stable base for future development.
  • Consultation period - with our understanding of the product we re-scoped the work. We suggested and implemented new features.
  • Our experience in developing HTML5 apps enabled us to advise Spark Energy on how to best improve the app’s user experience.

Meet Spark Energy 2.0

After the success of the first release, Spark Energy asked Red C to update their system. Most recently, Red C have upgraded the meter reading user interface and introduced an in app support chat for any users with questions that need to be answered right away. The new features are now in full swing and have had a positive response.

Project Highlight: Flexibility

With Spark we provided a ‘short sprint delivery’, once the app was in the store we provided Spark with weekly builds for the next 8 weeks. We used Trello, Spark's preferred Project Management tool to discuss how best to fix the bugs. We continue to be Spark Energy’s preferred mobile development partners.
