About This Property
This semi-detached house is located in CONWY, LL32 8AY. The property offers 420.76m² (4529 sq ft) of generously-sized living space with 7 habitable rooms. It is a period property with Victorian or earlier origins. With an EPC rating of D (65/100), this property is around the UK average for energy efficiency. The gas central heating system has good efficiency, indicating a relatively modern, well-maintained boiler. The solid walls lack insulation. Solid wall insulation (external or internal) typically costs £8,000-£14,000 but can reduce heat loss by up to 35% and improve your EPC rating by 1-2 bands. The pitched roof lacks adequate insulation. Topping up loft insulation to 270mm (the recommended depth) typically costs £300-£500 and could save £150-£250 annually, with the investment often paying for itself within 2-3 years. Double glazing is installed, though the efficiency rating suggests older units. Modern low-E double glazing can be up to 40% more efficient than units installed before 2002. Estimated annual energy costs are £2612, comprising £2361 for heating, £116 for hot water, and £135 for lighting. The property produces 15.0 tonnes of CO2 per year, which is high for a UK home.
