Why Does This Property Have a F Rating?
This terraced house is located in THAME, OX9 2BZ. The property offers 314.1m² (3381 sq ft) of generously-sized living space with 12 habitable rooms. It is a period property with Victorian or earlier origins. Currently rated F (33/100) for energy efficiency, this property would benefit significantly from energy improvements. With recommended improvements, it could achieve a D rating (56/100). The gas central heating system has average efficiency, indicating a boiler that may be 10-15 years old. While functional, upgrading to a modern A-rated condensing boiler could improve efficiency by 15-25%. The walls feature cavity wall insulation for improved thermal efficiency. 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 £3742, comprising £3118 for heating, £333 for hot water, and £291 for lighting. The property produces 23.0 tonnes of CO2 per year, which is high for a UK home.
