What is SAP?

SAP is the Governments 'Standard Assessment Procedure' for energy rating of dwellings. SAP, was designed to be included in the 1995 Building Regulations and it is now a compulsory component in Part L of the Regulations. Every new house has to have a SAP rating.

SAP calculations are required for all new dwellings as well as those that have been created as the result of material changes of use involving building work, and extensions over a certain size.


When do I need an 'As Built' or 'On Construction' EPC?

Since April 2008 in England and Wales when a new building is completed and is due to be signed off by Building Control (either as a new build or a conversion) it must have an 'As Built' SAP calculation and an 'As Built' (sometimes called 'On Construction') EPC produced. Both of these MUST be from SAP2009 software, NOT RdSAP (which is used for domestic EPCs on existing dwellings). Page 2 of an EPC clearly states which type it is.


English and Welsh 2013 Regulations

For the 2013 Part L Revision to the Building Regulations, they will be for the first time devolved in Wales. Though not yet introduced, Coles Knapp are abreast of both consultations which will implement much tighter energy regulations using markedly different methodologies and will be ideally placed to advise on compliance on both sides of the border.
