The team at Data Energy were using a legacy heat and utility billing software which involved a significant number of manual processes and was constraining their business growth.

They required us to replace this with a new, fully-automated, custom billing platform. This would allow the business to scale without significant additional resource.


  • Technical knowledge coupled with the ability to understand Data Energy's business processes in order to provide the right solution
    • Cloud experience to deliver security and scalability
    • The expertise needed to securely integrate on premise components into the solution

"During the development of this project we found Green Custard to be a strong partner who transformed our outdated and clunky systems into a contemporary solution that continues to evolve. Our clients have high expectations and we need partners who help us exceed these which was the case with Green Custard."

Rupert Mackay,

Director, Data Energy


Data Energy's new bespoke billing platform has given them the freedom they need to move to the next level. It delivers real change to the team's day-to-day working, allowing them to focus on their skill rather than cumbersome tasks.

We took on the challenge of managing the many sources of data and working effectively with existing on premise software, producing an end result which we are very proud of.

We look forward to continuing to work with Data Energy to automate further processes, benefiting the team and, in turn, their customer's experience.

"It was very interesting to see real world processes in action, and how software could free up time and improve on these." - Jonathan Custance, Director, Green Custard
