More variation at county level but similar trends

There is much greater variation at county than at national level. However, there are very discernible patterns such as Cork county has a high proportion of “B” ratings relative to other counties, whereas Offaly and Leitrim have a relatively high proportion of “G” ratings.

There are not many instances where a county has 20% or higher of the matched BERs in the “B” category. In the category reference person aged 18 to 34 years, 23% of dwellings in both Dun Laoghaire-Rathdown and in Cork county had a “B” rating. Among the 35-44 reference person age group, 26% of households in Cork county had a “B” rating. In contrast, only 6% of dwellings in Cork county with a reference person aged 75 years or over had a “B” rating.

Similarly, there are not many instances of a county having 20% or higher of “G” rated dwellings. However, in the reference persons aged 75 years or over category, 20% of households in Longford and 22% in Offaly had “G” ratings (see Figure 2.1).

Households with a mortgage and rented households have better energy ratings than homes owned outright. Cork county (26%), Galway county (23%), and Cavan (22%) had the highest proportions of “B” ratings among matched dwellings owned with a mortgage. In contrast, the highest percentage of “B” ratings for houses owned outright were 12% in Meath and 12% in Cork county.

Around 22% of reference persons in County Cork, who indicated that they were in very good health in the 2016 Census of Population, lived in a “B” rated dwelling. Wexford (9%), Galway city (9%), and Mayo (9%) had the lowest proportion of "B" rated dwellings for reference persons in very good health. In contrast, 19% of reference persons in Westmeath who were in very bad health lived in a “G” rated dwelling however there were only 42 matched households in this category. Donegal had a relatively high 15% of “G” rated dwellings for reference persons in very bad health based on 75 households in that category.

Around 14% of retired reference persons in Offaly and 13% in Leitrim lived in “G” rated dwellings. The proportion of “G” rated dwellings for reference persons who were unable to work due to sickness or disability was 12% in Westmeath and 11% in Leitrim.

Around 22% of student reference persons in Fingal and Dun Laoghaire-Rathdown lived in “B” rated dwellings compared with 4% of student reference persons in Galway city. Retired reference persons were one of the categories that tended to live a higher proportion of “G” rated than “B” rated dwellings. Farmer reference persons is another category where the proportion of “G” rated dwellings often exceeded the proportion of “B” rated households. The difference was particularly noticeable in Longford where 5% of farmers who were household reference persons lived in “B” rated dwellings compared with 19% of “G” rated households. Other counties with substantial differences were Galway county (8% and 17%), Leitrim (4% and 15%), Mayo (4% and 12%), Roscommon (8% and 17%), Sligo (7% and 14%), and Donegal (4% and 11%). Readers should note that a relatively low proportion of farm households have had a BER audit, so these figures should be used with an element of caution.

Households comprising couples with children tended to be more energy efficient - this is probably partially a reflection of the age of the dwelling. Fingal (19%), Louth (19%), Meath (19%), Cork county (24%), and Cavan (19%) had high proportions of “B” ratings for households of a couple with children. In contrast the percentage of “G” rated dwellings for persons living alone was 14% in Offaly, 14% in Leitrim, and 12% in Tipperary.

In general households where the reference person had a mobility disability were less energy efficient. For example, around 14% of such households in Offaly and 14% in Westmeath had a “G” rating. Less mobile persons may require higher levels of main space heating to keep themselves adequately warm.
