To prepare a BER certificate, one of Ability Property’s approved accessors will visit your property and conduct an in- depth on-site survey. During the Assessment, the property is measured and drawn, and areas of walls, ceilings, floors & windows, and door openings are also noted. The Assessor will investigate insulation, materials of construction, glazing, heating, hot water, and lighting systems. The BER survey is a non-intrusive survey i.e., we are not permitted to drill holes or dismantle panels to investigate levels of insulation. If this information is not readily visible or documented in a specific format, then the assessor will apply defaults based on SEAI guidelines.
