Trusted by businesses, proven results

How we overturned a £14,000 water bill for Ravensdale Junior School.

Learn how persistence from our Bill Validation and Water Procurement teams helped avoid a huge water bill after a school fire. When Ravensdale Junior School in Derby, part of Transform Multi-Academy Trust, received a water invoice that was significantly higher than usual, we got to work to investigate the cause. The culprit? A fire at an adjoining school on the site had been put out using Ravensdale Junior School’s water supply. We stepped in to resolve the issue, achieving an outstanding result for the school.

We have benefitted from significant savings by switching our energy and water to Zenergi. But more than that, the team helped to alleviate the shock and distress of an arson attack by taking care of managing everything for us and avoiding us having to pay a significant water bill.”

Powering a lasting partnership with Penwortham Girls’ High School

Penwortham Girls’ High School in Lancashire needed an energy partner they could trust – one that would simplify procurement. We stepped in to provide a fully compliant procurement service for the school’s gas and electricity contracts. By securing a fixed contract, we eliminated price uncertainty, helping the school accurately forecast budgets and avoid financial surprises.

Having Zenergi’s knowledgeable team take care of the complicated issue of budgeting and monitoring our energy consumption is so much more time-effective than us doing it internally. They also keep us informed of what’s happening in the market and any opportunities that could benefit the school."
Andrea Barnes Business Manager | Penwortham Girls’ High School

By October 2026 all electricity meters will need to be half-hourly. Don’t get left behind. If your meter is one of the circa 30 million affected by the regulation, it will need to be upgraded.
