About This Property
This terraced house is located in LLANELLI, SA14 7RG. The property offers 94m² (1012 sq ft) of good-sized living space with 4 habitable rooms. It is a recently constructed modern home. With an EPC rating of D (61/100), this property is around the UK average for energy efficiency. The oil-fired central heating has poor efficiency.

The property has modern timber frame or system-built walls, which typically offer good insulation properties when properly maintained. The property has good loft insulation, though topping up to the recommended 270mm depth could provide additional energy savings. Double glazing is installed throughout the property, providing good thermal and acoustic insulation. Estimated annual energy costs are £553, comprising £339 for heating, £170 for hot water, and £44 for lighting. The property produces 2.2 tonnes of CO2 per year, which is low for a UK home.
