Supporting informed choices, transparency, compliance and sustainability!

A new energy framework for schools in partnership with ISBL

Schools, academies and Trusts are facing increasing challenges, including rising energy costs, market volatility and demanding sustainability targets. To help address these issues, we’ve worked with the Institute of School Business Leaders (ISBL) to develop a compliant energy procurement framework designed to support effective planning, transparency and budget management.

Why choose the Zenergi ISBL energy framework?

Fully compliant and transparent

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

Best value through competitive pricing

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

Fixed or flex? You choose

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.

Built for sustainability

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

Real-time insights and intelligent monitoring

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.

Bill validation for confidence in every invoice

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

Comprehensive support beyond procurement

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.

What’s the process?

Understand your options

We’re happy to benchmark a quote – no assumptions, no obligations.

Authorise us to act on your behalf

All we need is a simple Letter of Authority (LoA) for us to use for discussions with suppliers and to gather any relevant information.

Receive tailored supplier quotes

We'll gather prices from our panel of pre-approved suppliers and present them back to you with our recommendation.

Finalise and proceed

If you'd like to proceed, we'll provide the supplier contract and Framework Participation Agreement, ensuring a trusted, compliant procurement route for your school.

The benefits you’ll see

Pricing transparency and budget certainty

Choose fixed or flexible pricing to balance budget control with market timing, guided by expert market insights.

Time savings

We act as your outsourced energy team, handling setup, supplier management and issues to save you time and avoid delays.

Enhanced efficiency

Beyond procurement, we validate bills for errors and give you easy access to powerful data through our user-friendly Portal.

Support for your sustainability goals

100% renewable electricity and expert support for net zero and carbon reporting. Our Greener Schools Index and ISBL-accredited training help school leaders track progress and drive real change.

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."

Tiana Walker Finance Director | Brigshaw Learning Partnership

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."
