Listed properties and EPC assessments

John Conlin / 21 February 2017

Chartered surveyor John Conlin explains why listed buildings don't have EPC assessments.


We are house hunting at the moment and ideally would like a period property but are concerned about running costs. 

I have noticed that listed properties do not appear to have EPC assessments whilst unlisted properties of similar age do. 

Why is this?

John Conlin: Buying a listed house - how liable am I?


There are two reasons. 

Firstly, the assessment calculation uses fixed heat loss values for various standard forms of construction (eg cavity brickwork, solid brickwork, rendering etc) which would not be accurate for the mix of older construction and materials.

Secondly, the primary aim of an EPC is to suggest ways of improving energy conservation most of which involve changes that would not be acceptable (eg double glazing) for a listed building.
