A SAP (Standard Assessment Procedure) is a number of calculations, including heat loss through walls, floors, roofs, heating and hot water, lighting etc, works out how energy efficient a dwelling is, showing a scale of 1 to 100 - from poor to excellent.

It is used to demonstrate compliance with Building Regulations Approved Document L1A by comparing the designed Dwelling Emission Rate (DER) with a SAP calculated Target Emission Rate (TER).

SAP 2005 works on a comparison basis that your house design was built to the 2002 Building Regulations, it will now from 2006 and onwards, have to be 20% more efficient.
So, for example, if the house cost £100 per year to run in 2002, in 2006 onwards it will only cost £80 per year to run.
