Today and tomorrow

We are here to empower organisations to better manage energy. Too many organisations struggle because they are hamstrung by poor data, limited visibility, or a lack of resources. We solve these problems and free our customers to get on with achieving real energy savings, fast.

About_Angie Howard Lucy 2

Big ideas from small beginnings

1981 was a great year for technology. The launch of the first PC, the first use of the term ‘internet’ and the ‘garage start-up’ of Stark. Our idea was ingenious and brave, to apply technology to solve organisations’ energy management problems.

Since launching our first product, a tariff analytics tool, Stark’s offering has evolved over the last 39 years to encompass our powerful energy analytics platform.

We haven’t stopped growing

We’ve continued to thrive from our humble beginnings and now process 18% of the UK’s energy consumption data every day. By building a team of fanatical energy and technology experts, our success is driven by our ability to generate creative ideas, roll our sleeves up and go the extra mile.

Monitoring over 73,000 sites in the UK and worldwide, we are the first choice for organisations wanting to better manage energy use, costs and performance.
