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 After 1997 homes at 39% of the housing stock. 27% of homes predate 1971, likely to have cavity-free solid-wall construction and low levels of insulation — the highest retrofit potential in the SEC. 39% 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 (32%) 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 — 64 homes without a BER, older construction with typically low energy performance. The 2001–10 band also stands out with 137 unassessed homes (relatively modern construction with lower improvement potential). BER coverage is strongest for Pre-1919 homes (68%).
Housing Tenure — Census 2022 vs Co. Clare
Owner-occupied homes account for 72% of SEC households, broadly in line with the Co. Clare average of 72%.
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, 26% of homes with a BER are rated B or better, compared with 30% in Co. Clare. The G band is the most over-represented (15% versus 11% in the county) and the A band the most under-represented (5% versus 8%). Nationally, 37% of homes with a BER are rated B or better, so the SEC is below Ireland, and 40% of its homes with a BER are in the D–G bands against 32% nationally. With 390 of the SEC's 818 homes having a BER (48%), confidence in these figures is moderate, and all seven Small Areas have SEAI data. BER ratings are the yardstick by which progress under the Climate Action Plan is measured. One national goal is to bring 500,000 homes (about 25% of homes) to a BER of B or better by 2030. In the SEC, 26% of homes with a BER are in the A0–B group, 44% in C–D and 30% in E–G. Homes in the C–D group are closest to the target and would generally need fewer measures to reach a B. The E–G group is where the greatest energy, cost and emissions savings per home could be made, and the SEC's share is above the county (25%) and Ireland (21%). Oil heats 76% of homes with a BER, against 54% in the county, which makes a switch to cleaner heating central to the project. Stone walls feature in 18% of homes with a BER versus 10% in the county, and these homes need specialist insulation approaches.
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 1.55 cars, above the national average of 1.43 (Co. Clare: 1.55). Only 8% of households have no car, compared with 14% for the national average — a sign of high car dependence, typical of rural areas with limited public transport. 51% of households run two or more cars (vs 45%). Second cars often cover shorter, predictable trips, making them strong candidates for replacement with an EV, shared transport or active travel.
