About This Property
This semi-detached house is located in PEMBROKE, SA71 5QJ. The property offers 102.35m² (1102 sq ft) of good-sized living space with 4 habitable rooms. It is a post-war property from the mid-20th century. The property holds an EPC rating of C (72/100), meeting the government's target standard for energy efficiency. The property benefits from a highly efficient gas central heating system, likely a modern condensing boiler achieving 90%+ efficiency. The property has good loft insulation, though topping up to the recommended 270mm depth could provide additional energy savings.

Upgrading to double glazing typically costs £400-£600 per window but improves thermal comfort and can reduce noise by up to 30dB. Estimated annual energy costs are £716, comprising £533 for heating, £108 for hot water, and £75 for lighting. The property produces 3.5 tonnes of CO2 per year, which is low for a UK home.
