The Standard Assessment Procedure (SAP) is the Government's approved
procedure for calculating an energy rating.
is a basic energy rating which assumes average factors for shelter,
shade and orientation and considers the space and water heating only.
The SAP scale
currently runs from 1 (extremely poor) to 120 (extremely good), with a score
of 80 or more considered to represent an energy efficient home.
The average UK home
(i.e. not brand new) has a SAP rating of 40-50.
homes achieve ratings of 80 or above, and there are many that reach top
scores of 100-120.
Building Regulations changed to require a SAP rating on every new home and
from 2001 builders had to post a notice in every finished dwelling stating
In June 2007 Home Information Packs (HIP) will be a
compulsory requirement for all homes sold in the UK.
The SAP rating will
form part of the HIP.
