Advisory improvement calculator
Energy Improvement Return On Investment Calculator™
Estimate whether an energy efficiency improvement may be financially worthwhile by comparing cost, annual saving, payback, lifetime net saving and return on investment.
This calculator provides general guidance only. Actual savings depend on property condition, energy prices, usage patterns, installation quality and official Energy Performance Certificate assessment results.
Calculate improvement return
Use simple estimates to create a plain-English view of payback, savings and whether the improvement looks financially attractive.
