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 54% of the housing stock. 18% of homes predate 1971, likely to have cavity-free solid-wall construction and low levels of insulation — the highest retrofit potential in the SEC. 23% 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 (54%) represents mid-vintage stock, often partially retrofitted but generally below current insulation standards.
House Age and BER Coverage
The 1991–2000 period accounts for the largest share of homes (29% of total). The greatest retrofit opportunity is the 1991–2000 band — 53 homes without a BER, construction that often predates modern insulation standards. The 1971–80 band also stands out with 32 unassessed homes (older construction with typically low energy performance). BER coverage is strongest for 1961–70 homes (66%).
Housing Tenure — Census 2022 vs Co. Clare
Owner-occupied homes make up 67% 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. Private rental is higher in the SEC (21%) than across the county (14%). Retrofitting privately rented homes is challenging — landlords bear the upfront cost while tenants receive the benefit in lower bills, a split-incentive that current grant schemes do not fully address.
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, 23% of homes with a BER are rated B or better, against 30% in Co. Clare. G is the most over-represented band (16% versus 11% in the county) and B the most under-represented (14% versus 18%). Some 44% of homes with a BER are in the D–G bands, against 38% in the county. Nationally, 37% of homes with a BER are rated B or better, so the SEC is below Ireland, and its D–G share is above the national 32%. With 188 of the SEC's 368 homes having a BER (51% coverage) and data for both Small Areas, confidence is high, though BERs tend to over-represent homes sold, let, newly built or grant-upgraded. BER ratings are the yardstick for progress under the Climate Action Plan; one national goal is to bring 500,000 homes (about 25%) to B or better by 2030. In the SEC, 23% of homes with a BER are A0–B, 45% C–D and 32% 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 their share is higher than in Co. Clare (25%) or Ireland (21%). Bulk LPG heats 17% of homes with a BER, against 2% in the county, so these homes may need new heating as well as insulation. Some 15% of homes with a BER have poor heat loss, against 10% in the county, making fabric upgrades a likely priority.
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 1.52 cars, above the national average of 1.43 (Co. Clare: 1.55). 11% of households have no car (the national average: 14%). 50% 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.
