About This Property
This semi-detached flat is located in GUILDFORD, GU1 1XP. The property offers 37m² (398 sq ft) of compact living space with 2 habitable rooms. It is built during the 1980s construction period. With an EPC rating of D (67/100), this property is around the UK average for energy efficiency. With recommended improvements, it could achieve a C rating (72/100). The gas central heating system has good efficiency, indicating a relatively modern, well-maintained boiler. The walls feature cavity wall insulation with good efficiency ratings, providing solid thermal performance. 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 £488, comprising £332 for heating, £105 for hot water, and £51 for lighting. The property produces 1.8 tonnes of CO2 per year, which is very low for a UK home. For landlords: This rental property with a D rating is positioned above the current minimum standard. With proposed changes to require a C rating by 2028, modest improvements now could future-proof your compliance.
