Age of Homes — Census 2022, permanent private households
Houses by Age Group
Pre 1971 1971–1996 After 1997 Not stated
The largest age cohort is 1971–1996 homes at 45% of the housing stock. 13% of homes predate 1971, likely to have cavity-free solid-wall construction and low levels of insulation — the highest retrofit potential in the SEC. 40% were built after 1997 when Ireland's Building Regulations (Part L) introduced mandatory energy efficiency requirements, with further tightening in 2006 and 2011. The 1971–1996 cohort (45%) represents mid-vintage stock, often partially retrofitted but generally below current insulation standards.
House Age and BER Coverage
The 2001–10 period accounts for the largest share of homes (34% of total). The greatest retrofit opportunity is the 1971–80 band — 126 homes without a BER, older construction with typically low energy performance. The 1991–2000 band also stands out with 185 unassessed homes (construction that often predates modern insulation standards). BER coverage is strongest for Post-2010 homes (93%).
Housing Tenure — Census 2022 vs Co. Clare
Owner-occupied homes make up 62% of SEC households, below the Co. Clare average of 72%. With fewer owner-occupiers relative to the county, the SEC may face greater challenges in retrofit uptake, as landlords have weaker financial incentives to invest in energy upgrades. Social and institutional housing is above the county average: 12% Local Authority (vs 6% countywide) and 5% voluntary/co-operative body (vs 1% countywide). Working directly with the Local Authority or housing body to deliver group retrofit programmes can be more effective than engaging large numbers of individual private landlords, each with only a small portfolio of properties.
BER Ratings — % of homes with a BER vs Co. Clare and Ireland
Homes with a BER by rating group
A0–B C–D E–G
In the SEC, 33% of homes with a BER are rated B or better, against 30% in Co. Clare. Band C is the most over-represented (36% versus 32%) and band G the most under-represented (2% versus 11%). Some 30% of homes with a BER are in the D–G bands, compared with 38% in the county. Nationally, 37% are rated B or better, so the SEC is below Ireland. With 1,488 of the SEC's 2,229 homes (67%) holding a BER and data for all 17 Small Areas, confidence is high, though homes that were sold, let, newly built or upgraded with a grant tend to be over-represented. BER ratings are the yardstick by which progress under the Climate Action Plan is measured, and one national goal is to bring 500,000 homes (about 25%) to B or better by 2030. In the SEC, 33% of homes with a BER are in the A0–B group, 54% in C–D and 13% in E–G. C–D homes are closest to the target and would generally need fewer measures to reach a B. E–G homes offer the greatest energy, cost and emissions savings per home and make up 13% of homes with a BER, against 25% in the county and 21% nationally. Poor heating controls affect 62% of homes with a BER, against 53% in the county, so controls upgrades could be a measure shared across many homes. Gas heats 36% of homes with a BER, against 13% in the county, which shapes planning for a move to low-carbon heating such as heat pumps.
Cars per Household — Census 2022, scaled × 1.109 to 2025
% of households, Census 2022. Pie chart counts are scaled to 2025; percentages are unchanged by scaling.
Households in the SEC have an average of 1.30 cars, below the national average of 1.43 (Co. Clare: 1.55). 15% of households have no car (the national average: 14%). 36% of households run two or more cars (vs 45%).
