A new energy framework in partnership with ISBL

Choice, transparency, compliance and green energy starts here!

We understand the growing pressures schools, academies and Trusts face – from rising energy costs and volatile markets to ambitious sustainability targets.

 

That’s why we’ve partnered with the Institute of School Business Leaders (ISBL) to offer a fully compliant energy procurement framework that gives you clarity, confidence and budget control.

Gain clarity, confidence and control

Why choose the Zenergi ISBL energy framework?

Procured under the Procurement Act 2023 with full legal oversight, ensuring a transparent and secure process from start to finish.

Access a mini-tender process with 12 pre-approved suppliers for competitive pricing.

To support budget certainty we can offer fixed contracts, alternatively, for those seeking both cost control and trading flexibility, ZenFlex Secure offers the ideal solution, spreading purchasing over time to avoid short-term market volatility while optimising long-term value.

All electricity supplied is from 100% renewable sources, with expert guidance to help embed sustainability, reduce emissions, and progress your net zero strategy.

With our Portal, gain instant access to energy data, and take control of your energy usage and spend. With key features including comprehensive reporting and data exports, simple meter read submissions, bulk bill downloads and access control for multi-site organisations, you’ll have all the information at your fingertips for accurate forecasting and budget tracking.

We validate energy bills against your contract and usage, identifying and resolving discrepancies directly with the supplier and recovering any overpayments for you.

From contract tendering and meter registration to bill validation, supplier liaison, and post-contract support, we’re with you every step of the way. And if you’re interested in tracking market changes, benchmarking usage, or engaging students through social value initiatives, Zenergi delivers expert support to help you achieve your energy, carbon reduction and cost saving goals.

Trusted by schools, proven results

Helping Brigshaw Learning Partnership save £18,000 on energy costs.

We helped Brigshaw Learning Partnership move away from a Public Buying Organisation (PBO) framework to a fully managed energy service. The result? A 28% saving on their gas contract, plus ongoing expert support. With this transition, the Trust is not only saving money but also unlocking new opportunities for smarter energy management.

Brigshaw Learning Partnership moved from buying through a framework to a broker arrangement. We have made significant savings and are enjoying the added benefit services and advice from Zenergi."

Identifying hidden costs and reclaiming energy bill overpayments.

When Broad Horizons Education Trust chose us to manage energy procurement across all its schools, they gained more than just competitive contracts. During onboarding, we identified years of incorrect charges at multiple sites, and our team stepped in to recover the overpayments.

 

 

 

Not only has Zenergi delivered significant value by obtaining a refund for historic overpayments, but we can access the full range of services from an organisation that understands our requirements."
Chief Operating Officer | Broad Horizons Education Trust

Leigh Academies Trust saves £500,000+ through flexible energy purchasing.

When faced with a significant renewal cost increase, Zenergi hosted a tailored workshop for the Trust to explore alternative procurement options available to the group. Leigh Academies opted for Zenergi’s Zen Flex Bespoke product, allowing them to mitigate volatility by purchasing energy in advance and trading on the day-ahead market.

 

 

The Zen Flex Bespoke product has helped us navigate the volatile energy market, achieve significant cost savings and budget certainty. We’re extremely pleased with the results and would recommend Zenergi to any organisation seeking to optimise energy costs."
Richard Cottam MSc | Leigh Academies Trust Deputy Estates Director

Simplifying energy procurement and unlocking savings for Holy Cross Catholic MAC.

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.
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."
