Why Does This Property Have a G Rating?
This semi-detached house is located in ST. ALBANS, AL3 7QA. The property offers 132m² (1421 sq ft) of spacious living space with 6 habitable rooms. It is a characterful interwar or early 20th century home. Currently rated G (16/100) for energy efficiency, this property would benefit significantly from energy improvements. With recommended improvements, it could achieve a C rating (78/100). The oil-fired central heating has poor efficiency. Oil boilers are more expensive to run than gas and have higher carbon emissions. Consider switching to a heat pump (eligible for £7,500 BUS grant) for significant long-term savings. 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 £2797, comprising £2216 for heating, £457 for hot water, and £124 for lighting. The property produces 8.9 tonnes of CO2 per year, which is high for a UK home.
