Mr. Chris Hughes:

I recall that close to 1 million homes had a BER at one point. Some have expired and the current number is that approximately 56% homes have active BERs. There is a full breakdown of that on the Central Statistics Office, CSO, website. We provide BER data on a regular, quarterly basis to the CSO. It combines those data with census data and scale that up to population. There is a full breakdown by heating system type, county, year of construction and fuel type on the CSO website under its climate and environment section.
