About This Property
This terraced house is located in DARLINGTON, DL1 5EQ. The property offers 74m² (797 sq ft) of modest-sized living space with 3 habitable rooms. It is a period property with Victorian or earlier origins. With an EPC rating of D (57/100), this property is around the UK average for energy efficiency. With recommended improvements, it could achieve a B rating (85/100). 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 £1038, comprising £816 for heating, £124 for hot water, and £98 for lighting. The property produces 4.3 tonnes of CO2 per year, which is moderate 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.
