A Singular Vision

We believe in challenging convention and are redefining software for oil and gas.

Our purpose

We challenged ourselves to rethink software for oil and gas from the ground up, and created the EnergySys Cloud Platform. The first 100% cloud-native platform for production allocation and reporting.

To make it as simple, efficient and easy to use as possible. From the integration of new assets, to the validation of data, to the reporting of results. We also recognised that regular software upgrades are an essential part of application ownership, that must be delivered with almost zero service interruption, no additional costs, and no impact on the configured applications and data. Finally, we rejected the standard pricing models used in the industry and looked to deliver predictable total cost of ownership without the need to worry about obsolescence or expensive upgrade costs eating away at your bottom line. 

We have decades of experience in hydrocarbon accounting, which means we offer superb customer support at no additional cost, which is responsive and personal, and consistently receives praise from our clients.

"The EnergySys team have been there whenever we’ve needed any help. Their direct and immediate support model truly sets them apart.” - BP Lower 48

Our Net Zero Pledge

EnergySys has committed to achieving net zero emissions by 2050, as part of the UK’s Business Climate Leaders campaign.

As part of this initiative, we are working towards halving our greenhouse gas emissions by 2030, and achieving net zero by 2050.

As we are already a cloud-native, remote-working organisation, this decision was a natural next step for us.

In our paper on net zero, we outline what cloud computing has the potential to do for the environment and the impact energy companies have.

We are confident that our pledge will make for a better future for our planet.

If you're interested in the steps we're taking to meet our pledge, we'll be keeping this page updated with every stage of our climate-conscious journey.

Our leadership team

We recognise that people buy from people. You want to know that the key individuals in any company are people you can trust. People with experience and a track record of delivery. People who are as immersed in your industry as you are, and who can understand what you need. While our delivery is in the cloud, that doesn’t mean we want to keep you at arms length, and every one of our team is available to respond to whatever queries you have.

20 years of innovation

We have decades of experience in delivering production accounting systems, which means we really understand your needs.

We recognise that you'll have genuine questions and don't want to be approached by a sales team, which is why we don't have one.

Instead, speak to someone who actually uses the platform and can answer your questions in extensive detail. Find out more about how the revolutionary EnergySys Cloud Platform could work for you.


Our customers are our lifeblood, our extended family, and are as committed to EnergySys as we are.

With their invaluable feedback, identifying their unique set of challenges and goals, we are able to evolve the EnergySys Cloud platform and apps to solve their business problems, not just sell them something that sounds good on paper.

Here’s a selection of our clients and their stories.


Sharing is caring

We strongly believe in collaboration and the sharing of ideas, so we've taking sharing to the next level. Using our team's experience, we continually add new content to our resources section in the shape of blogs, papers, videos and news - it's everything you need to keep on top of the HCA game.
