The Primary Graphics Rating:



All the contents of the certificate are important as they convey valuable information. The primary rating graph showcases the energy efficiency of the property. The efficiency is showcased with the help of a colored scale that ranges from A to G.

The A in the dark green is for the most efficient and the G in red is used for the least efficient properties. The letters are also assigned numbers and the numbers start from 1 and go up to 100.

One arrow is for the current energy efficiency of the property and the other indicates the potential rating that a property can reach with proper energy efficient techniques.


The Estimated Costs:


After the graph, the certificate includes a table of estimated costs. The estimated cost is calculated by considering the size of the house. It is possible for two houses to have the same energy rating but different estimated energy cost because of the size difference. The first column mentions the categories like lighting, heating, hot water, etc. The second column is for current cost of energy consumption while the third column gives the potential costs that you can achieve with energy efficient practices.
