This 3-bedroom detached at Teach Mor, Lettermullen, Lettermullan, Co. Galway, H91X3NF is currently listed for sale at €425,000. The home has a floor area of 128 m², a BER energy rating of D1.
Rough estimate based on the BER cert's primary energy band — covers the four 'regulated services' SEAI DEAP measures: space heating, hot water, lighting, ventilation. It does NOT include appliances, cooking, IT equipment, or real-life usage variance (occupancy, comfort temperature, hours at home). Actual bills will differ.
2026-05 Irish retail unit prices (Switcher.ie / SEAI Domestic Fuels Q4 2025): Mains Gas €0.10/kWh · Heating Oil €0.10/kWh · Electricity €0.30–€0.40/kWh (smart vs standard) · LPG €0.15/kWh · Solid fuel €0.06–€0.09/kWh. ±15% margin on non-electric. Standing charges: €300/yr electricity meter, +€360/yr if gas is connected.
Calculation: 242 kWh/m²/yr × 128 m² = 30,976 kWh/yr (primary energy from the BER band). Primary → delivered uses SEAI DEAP factors (fossil ~1.10, electric ~2.08). Delivered kWh then splits 85% main fuel (Heating Oil) + 15% electricity (lighting + ventilation always run on grid), with standing charges added. The fuel choice is the mode from this Small Area's BER records — single-property accuracy isn't guaranteed.
