A PEA is a Predicted Energy Assessment and is produced as part of the design stage SAP, if required. Many building and construction companies sell properties off-plan – in other words, the builder sells the property to a buyer before the building has been built – and, in order to do so, they must have a valid PEA.
The PEA is also used during the early stages to identify any areas which can be improved to bring the band of the PEA/EPC up if required.
