What is the average EPC rating? and what proportion of properties fall into each A+, A, B, C, D, E, F, G EPC asset / band rating?

Low Carbon Energy Assessors (LCEA) Ltd has carried out research on the Information lodged on the UK Government’s Energy Performance Buildings (EPB) Register for England and Wales. We have analysed the lodgment data regarding the Energy Performance Certificates (EPCs) that have been issued for domestic dwellings and commercial non-domestic buildings. The EPC is required when a property is being advertised for sale, let, including the first fit-out for a shell and core building or newly constructed property, this is a legislative requirement since 2008.

Our research has identified what the average EPC rating is for domestic and commercial properties, and the volume of EPCs lodged onto the register due to the legislative requirements. We have also identified the percentage proportions of these properties that fall into each of the EPC asset band ratings between A, B, C, D, E, F, G for domestic properties and A+, A, B, C, D, E, F, G for commercial properties.

How many EPCs have been lodged to date?

By the end of June 2014 a total of over 12 million Energy Performance Certificates (EPCs) for domestic and commercial properties have been lodged onto the UK Government’s EPC Register for England and Wales since it first came into operation back in 2008.

What about domestic EPCs?

More than eleven and half million EPCs covering domestic properties have been lodged on the EPC Register since it first came into operation. Of these lodgments over 900,000 covered new dwellings, accounting for around 8 per cent of the cumulative total.

Domestic properties accounted for 96 per cent of this cumulative total covering dwellings such as Houses (accounted for 59 per cent of the total), Flats (26 per cent), Bungalows (8 per cent), and Maisonettes (3 per cent).

The cumulative percentages of all the domestic EPC ratings given an Energy Efficiency Rating of either A (the highest) or B worked out to be in the region of 9 percent; 66 per cent were given a Rating of C or D; and the remaining 25 per cent were given a Rating of E, F or G (the lowest).

EPC percentage splits for Domestic EPCs asset / band Ratings

Domestic Energy Performance Certificates (EPCs) lodged on the UK Government’s Register by Energy Efficiency Rating which fall into each A to G asset / band ratings: –

A      0.09%                          epc rating explained                            

B      8.39%

The above is the cumulative total number of Domestic EPC Lodgments for the period from 2008 to the end of June 2014. The statistical data consisted of 11,765,227 EPCs that were lodged onto the UK Government’s Register. These domestic EPCs had a total floor area of 988,754,889 m2.


What about Commercial / Non Domestic EPCs?

The commercial / non-domestic EPCs accounted for over half a million EPCs that had been lodged onto the Register by the end of June 2014 and this accounted for the remaining 4 per cent of all cumulative EPC lodgments since 2008.

Within this total, around 8 per cent of non-domestic / commercial properties were given an Energy Performance Asset Rating of either A+ (the highest), A or B; 56 per cent were given a Rating of C or D; and the re-maining 36 per cent were given a Rating of E, F or G (the lowest / worst).
