Below you will find a comparison chart on the different BER energy rating certificates and how they impact your annual energy bills - If You require any further information please contact our BER assessors today we will be glad to answer any questions your have on (Building Energy Rating Certificates). What is the difference between an A rated property and a G rated property and how much will I save by having a better rating certificate ? If we take the below chart as our example - all properties are identical in size and the energy cost is (€0.14/kWh) kilo Watt per hour the only difference. You will see a house that has an energy rating certificate of A1 / A2 / A3 will save more money annually on their energy bills. As you will see the graph starts at A1 rating and finishes at G rating Green to red. If your property is rated anywhere between A1 and B3 your property will save a sigifigant amount of energy per year. If your property rating is any where between C1 & Rating G your property is loosing heat through various parts of your house, this maybe insulation or other means. House A1: BER value = 25 kWh/ m2 /y House A1 = € 343 energy costs per year House A2: BER value = 25 kWh/ m2 /y House A2 = € 343 energy costs per year House A3: BER value = 50 kWh/ m2 /y House A3 = € 686 energy costs per year House B1: BER value = 75 kWh/ m2 /y House B1 = €1,029 energy costs per year House B2: BER value = 100 kWh/ m2 /y House B2 = €1,372 energy costs per year House B3: BER value = 125 kWh/ m2 /y House B3 = €1,715 energy costs per year House C1: BER value = 150 kWh/ m2 /y House C1 = €2,058 energy costs per year House C2 : BER value = 175 kWh/ m2 /y House C2 = €2,401 energy costs per year House C3 : BER value = 200 kWh/ m2 /y House C3 = €2,744 energy costs per year House D1: BER value = 225 kWh/ m2 /y House D1 = €3,087 energy costs per year House D2 : BER value = 260 kWh/ m2 /y House D2 = €3,567 energy costs per year House E1 : BER value = 300 kWh/ m2 /y House E1 = €3,087 energy costs per year House E2 : BER value = 340 kWh/ m2 /y House E2 = €4,116 energy costs per year House F : BER value = 380 kWh/ m2 /y House F = €5,214 energy costs per year House G : BER value = 450 kWh/ m2 /y House G = €6,174 energy costs per year If you require a BER certificate for your property please contact our BER assessors on 01 - 4297878 we provide a quality service and will ensure your property receives an accurate energy rating audit.
