Ireland energy costs

Source: CRU Typical Domestic Consumption Values + SEAI average unit price statistics (cost estimated from consumption × typical rates, not a direct CRU total-bill figure)

Gas use is heavily concentrated October–April for heating; electricity use is also higher in winter. SEAI tracks this monthly, but no single official ‘winter vs summer’ percentage is published — comparison-site estimates suggest combined bills can run 2–3x higher in winter, though this isn’t an official CRU/SEAI figure.

Bars show a relative index (100 = year-round average month) illustrating the pattern described above — no regulator publishes an exact month-by-month bill, so treat this as a shape, not a precise figure.
