An Energy Performance Certificate (EPC) is required whenever a new building is constructed, or an existing building is sold or rented out.
An EPC is a measure of the energy efficiency performance of a building and is rated from band A – G, with A representing the best performance. The EPC ratings correspond to a range of SAP ratings from 1 – 100, with 100 being the best. It is possible, therefore, to give a dwelling an EPC rating based on the SAP rating.
The image below shows the bands A – G and corresponding SAP ratings in brackets. The first two columns show the number and percentage of Preston’s private sector stock falling into each of the EPC ratings bands. The third column shows the comparable figures for the private sector stock in England.
The estimated average SimpleSAP for the private sector stock in Preston is 61 which corresponds to an EPC rating of D. The number of private sector dwellings with an EPC rating below band E is estimated to be 2,327 (4.6%). Compared to the England figure, Preston has a slightly lower proportion of dwellings in all
the bands except band D.
