Why Does This Property Have a F Rating?
This semi-detached house is located in LONDON, SE21 8DS. The property offers 129.38m² (1393 sq ft) of spacious living space with 8 habitable rooms. It is a period property with Victorian or earlier origins. Currently rated F (37/100) for energy efficiency, this property would benefit significantly from energy improvements. With recommended improvements, it could achieve a E rating (44/100). 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. The roof space has been converted to living space, with insulation between the rafters. 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 £2440, comprising £2059 for heating, £192 for hot water, and £189 for lighting. The property produces 14.0 tonnes of CO2 per year, which is high for a UK home.
