School Energy Savings Estimator
*If multiple buildings, use the rating of your largest/highest-consuming building.
Estimated Annual Savings
£0
Based on a 0% saving rate applied to 61% of your bill.
*Calculations are estimates based on your provided data and Energenie's proprietary methodology.
Understanding Your Results
Your estimated saving is a powerful projection of how much money you can reallocate back to classrooms, staff, and student resources annually.
1. Estimated Annual Monetary Savings (£)
This is the bottom-line figure: the estimated amount you will save each year by implementing the chosen heating control solution.
How We Calculate It: Transparency in Methodology
To ensure accuracy without requiring complex building surveys, our calculation is based on three key factors:
Focus on Heating (61% of Your Bill): School budgets show that, on average, 61% of total energy consumption goes directly toward heating and hot water. Since our solutions target heating systems, we isolate this portion of your bill for the savings calculation.
The EPC Multiplier (Site Complexity Multiplier): The EPC rating determines the inherent efficiency (or inefficiency) of your building fabric. A lower rating (like E, F, or G) means greater potential for immediate savings from controls. Our calculator uses this rating to apply a specific multiplier to ensure the result is realistic for your specific building quality.
For example, an EPC of A (highest efficiency) uses a minimal multiplier (0.1), whereas an EPC of G (lowest efficiency) uses the maximum multiplier (1.3), reflecting the high potential for improvement.
Solution Deployment Factor (SDF): This is a fixed, proven factor based on the technology:
TRVs: Assumed to deliver a 25% saving on the heating portion of your bill.
Relays/Stats: Assumed to deliver a 15% saving on the heating portion of your bill.
2. Estimated Savings Percentage
This percentage shows the combined impact of your EPC Rating (the multiplier) and the Solution Deployment Factor.
The estimated saving is designed to be a strong foundation for your Return on Investment (ROI) assessment. Ready to turn this estimate into a reality?
Unlock Hidden Savings: Use Our School Energy Savings Calculator
As a Headteacher or School Bursar, you are constantly tasked with optimizing budgets and finding ways to redirect funds from utilities back into education. Our proprietary calculator, developed using real-world data from school estates, provides a clear, rapid estimate of the savings achievable through simple, proven heating control upgrades.
Stop letting energy waste deplete your budget. Find out how much you can save in seconds.
How to Use the Calculator in 3 Simple Steps
The Energenie calculator is designed to be quick and intuitive, focusing only on the data points that directly influence your savings potential.
Enter Your Annual Energy Bill (£): Input the total cost of energy (electricity and fuel) for the last calendar year. This gives us the baseline we need to assess the savings impact.
Select Your Most Representative EPC Rating: Choose the Energy Performance Certificate (EPC) grade that best represents your main teaching facilities. If you have multiple buildings with different EPCs, please select the rating of your largest or highest-consuming building. This is crucial for accurately determining the starting point for savings.
Select Your Proposed Solution: Choose between TRVs (Thermostatic Radiator Valves) or Relays/Stats (Smart Controls). These are the two most cost-effective heating solutions for schools.
