SAP & EPCs

SAP and On Construction EPCs are necessary items, linked to the measurement of energy performance, when building works now take place in a property.

Celotex offer specialist advice and guidance in this area through our dedicated team of trained assessors.

What is a SAP Calculation?

SAP is the Government’s Standard Assessment Procedure for calculating the energy rating of dwellings (homes). SAP is a compulsory element of Approved Document L of the Building Regulations 2006, meaning that all new homes are required to have a SAP rating - attained through undertaking a SAP calculation to gauge the standard of energy efficiency achieved.

SAP is a whole building energy calculation and looks at:

• The size of the property
• Type and size of openings (doors and windows)
• Provision of heating, lighting and hot water

SAP is used to produce an Energy Performance Certificate for a new home. These are required by law to be provided to owners or tenants of new homes.

What is an On Construction EPC?

EPCs record how energy efficient a property is as a building and provide performance ratings from A-G – similar to the labels commonly seen on household appliances such as freezers and washing machines.

EPCs are issued after the property is built, and are produced using standard methods and assumptions about energy usage so that the energy efficiency of one building can be easily compared with another of the same type. This allows prospective occupiers to consider energy efficiency and fuel costs before committing to a property.

EPCs are legally required for all homes, whenever they are built, rented or sold. As legal documents, EPCs can only be produced by accredited energy assessors.
