What is a On Construction EPC?

An on construction epc certificate records how energy efficient the property is as a building and provides  A – G ratings. These are similar to the labels now provided with domestic appliances such as refrigerators and washing machines.

On Construction EPCs are produced off plan using full SAP (standard assessment procedure) this is more accurate than RdSAP as used in existing dwellings because all the build specification is available to the assessor.

On Construction EPCs (SAP)are required before a new build can be certified by building control, EPCs are also required for the sale and let of new build properties, new build properties can be marketed at the design stage as the assessor can produce a PDA (Predicted Energy Assessment) off the plan and build specification before the property is built. The property has to be  completed before the full EPC can be issued.

New buildings must comply with Building Regulation Part 1LA  and the Air Tightness Test result is calculated in to the EPC calculation, the result of the Air Tightness Test affects the rating.

Property extensions may also be required to have a SAP rating from Building Control before the work can be signed off.

Price is dependant on number of properties being assessed. Please call for a quote.
