ISBL Energy Framework

Powered by Zenergi

Smarter, greener, compliant energy procurement for your school or trust

Managing your energy is more challenging than ever. With rising costs, turbulent markets, and increasing sustainability pressures, you need an energy solution that gives you full visibility to protect your budget, while supporting your sustainability goals.

The ISBL Energy Framework, delivered in partnership with Zenergi and South West Essex Community Trust, is a fully compliant, competitive, and flexible route to energy procurement. It is specifically designed to support schools, academies, trusts and wider public sector organisations.

Your data, your way - with the Zenergi Portal

Gain real-time insights into your energy usage and costs with a powerful platform that puts you in control:

  • Fast, user-friendly data filtering and export (PowerPoint, CSV, PDF)

Bill Validation – Confidence in every invoice

Incorrect energy bills are a common – and costly – frustration for public sector organisations. That’s why bill validation is a standard part of our service under the Framework. Zenergi checks every invoice to ensure it matches your contract terms and reflects actual usage. If something doesn’t add up, the team will step in to resolve discrepancies directly with the supplier, so you don’t have to. This service gives you peace of mind that you’re paying the right amount – and nothing more.
