In order to produce a BER certificate one of our assessors will need to survey the dwelling. When you book a BER assessment with us we will schedule an appointment for a time that is most convenient for you. It is important that the assessor has access to all areas of the house.
During the survey, the assessor will sketch the layout of the dwelling and its measurements. The survey is completely non intrusive. The calculations are based purely on the materials and heating equipment that are present, it does not matter how well the equipment is working or how it is used.
During the survey the assessor will be measuring the area of the rooms, measuring the windows, the thickness of the walls, the levels of insulation, the heating system, the number of flues, the floor types and the wall types. The assessor typically collects approximately 80 pieces of data which describe your home. The survey itself usually takes about an hour but can vary with the complexity or size of the dwelling. They will then use this data in their calculations when producing your building energy rating.
