Why Does This Property Have a F Rating?
This semi-detached flat is located in PENZANCE, TR18 4LS. The property offers 120m² (1292 sq ft) of spacious living space with 5 habitable rooms. It is a period property with Victorian or earlier origins. Currently rated F (23/100) for energy efficiency, this property would benefit significantly from energy improvements. Heating is provided by oil-fired central heating. While effective, oil prices can be volatile and the system produces higher carbon emissions than gas or heat pumps. 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. Single glazing is a significant source of heat loss, accounting for up to 25% of a home's heat escaping through windows. 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 £2251, comprising £1871 for heating, £267 for hot water, and £113 for lighting. The property produces 11.0 tonnes of CO2 per year, which is high for a UK home.
