Site visits & Inspections


If required, site visits will be arranged and carried out as agreed, in order to ensure that installations are performed as required in various stages, and will provide a building certificate stating that everything is installed within the BASIX and BCA parameters/requirements as specified. This process is very useful for obtaining the OC easily. 

As of June 2015 BASIX has issued a new specification which all drawings must adhere to for the purposes of a NatHERS Thermal Comfort Simulation Assessment. Please be advised the AENEC is fully compliant with the latest version of AccuRate Sustainability.
