About This Property
This semi-detached maisonette is located in ST ALBANS, AL1 1PD. The property offers 37m² (398 sq ft) of compact living space with 2 habitable rooms. It is a post-war property from the mid-20th century. With an EPC rating of D (66/100), this property is around the UK average for energy efficiency. With recommended improvements, it could achieve a C rating (75/100). 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. 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 £495, comprising £390 for heating, £67 for hot water, and £38 for lighting. The property produces 2.0 tonnes of CO2 per year, which is 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.
