True enabled us to assess the validity of solar for our business. By combining accurate energy procurement costs with emission reduction data, we can compare the performance of multiple suppliers against our business criteria and confidently forecast the financial and carbon impact of the initiative.

Having True will be a one stop to understanding site's requirements and the energy initiatives that they are reviewing with direct and accurate measurement of the true return on investments. We can be more prudent with the ESOS3 audits and initiatives that will be reviewed in True.

True brings together a lot of disparate strands that you can apply to a sustainability investment. Calculating costs, carbon benefit, or payback are things that can get people scratching their heads but with True, you can do that calculation in a matter of seconds.

We appreciate the personalised support from the True team, whose expertise helped us navigate market volatility and mitigate risks effectively. Their flexible strategy and clear recommendations allowed us to reduce exposure to high energy prices, providing confidence for our budget planning.

True takes the hassle and guesswork out of validating, comparing and deciding on which renewable technologies to use and which suppliers to choose. The combination of real-time energy procurement data with carbon emissions data in one platform allows you to accurately forecast and plan your net zero projects and strategies.

True enables businesses to assess the impact of investments in renewable energy and understand how they deliver against Net Zero goals, all while energy costs are brought down and emissions are lowered. I think this is a game changer for companies who genuinely want to develop a road map to Net Zero and save money.
