Simplifying Energy Procurement and Unlocking Savings for Holy Cross Catholic MAC

In their words:

I find Zenergi’s service to be excellent and pricing very competitive. The Directors asked for a second tender to ensure that Zenergi was offering the cheapest solution. The Zenergi contracts were lower priced than the competitive tender and the online portal is also a good resource.

Holy Cross Catholic MAC

Managing energy contracts for multiple schools can be complex and time-consuming. Holy Cross Catholic Multi-Academy Company (MAC) wanted to simplify its procurement process, ensure cost transparency and uncover opportunities to save. With one of its secondary schools already benefiting from Zenergi’s services, the Trust decided to bring all seven schools under our care.

 

Our solution

Zenergi partnered with Holy Cross Catholic MAC to take full control of its energy management, streamlining processes and unlocking hidden savings:

  • Simplified procurement: We aligned contract end dates across all schools and provided a wide range of suppliers and contract terms, making Energy Procurement easier and more transparent
  • Smarter decision-making: Directors were equipped with clear, like-for-like comparisons of energy contracts, enabling smarter budgeting and better governance
  • Greater flexibility: Freed from long-term commitments made months in advance, the MAC gained confidence and clarity in its energy decisions

Spotting errors and claiming savings

Hidden billing errors can significantly impact budgets, but our Bill Validation Service ensured Holy Cross Catholic MAC was only paying what it should. Our team uncovered overcharges on VAT and the Climate Change Levy (CCL) across several schools, successfully claiming back these overpayments and returning valuable funds to the MAC’s budget.

Driving additional value

Our partnership extends beyond cost saving:

  • Actionable insights: Through our user-friendly customer portal, the MAC gained detailed visibility into energy consumption
  • Improved sustainability: Granular data helped the MAC identify opportunities to reduce energy use and make sustainable decisions
  • Better budgeting: Accurate data and streamlined processes allowed for more effective budget planning and cost control

The result

Working with Zenergi transformed energy management for Holy Cross Catholic MAC, delivering tangible benefits:

  • Recovered VAT and CCL overpayments to boost budgets
  • Aligned energy contracts across all seven schools, simplifying management and renewal processes
  • Enhanced visibility into energy usage through detailed insights
  • Supported smarter budgeting and reduced consumption
