The Pre-BER will accurately determine your home's current energy efficiency level on a scale of A to G which gives you a baseline to work from.
Annual fuel costs can be estimated based on your home's energy efficiency, your primary heating system, and the heat source used to heat your home.
Potential savings can be estimated based on your current BER and your target BER which can then be used to evaluate the payback on your investment.
It's impossible to know the improvements you have achieved to your home's energy performance if you don't first know what your current energy performance is before you start. We highly recommend customers get a BER Assessment carried out on their home at the start of their Energy Efficiency project. This will indicate your home's energy performance and provide you with the information you need to make informed decisions on choosing the correct measures to upgrade.
Your BER is calculated on the amount of energy use for space and hot water heating, ventilation, and lighting. The number of people likely to occupy a building is also taken into consideration. Your BER is valid for 10 years and is a mandatory requirement if you are buying or renting a home.
