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 — 55 homes without a BER, construction that often predates modern insulation standards. The 1971–80 band also stands out with 33 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 assessed homes vs Co. Clare (2025)
The SEC's energy profile lags the county average: 18% of assessed homes are A or B rated, compared to 54% countywide (2025). The SEC has proportionally more D-rated homes than the county (21.3% vs 9.7%). Conversely, A2-rated homes are under-represented in the SEC (1.7% vs 13.0% countywide). With 47% of assessed homes in the D–G bands (vs 22% countywide), there is significant retrofit potential in the SEC.
