Why Does This Property Have a G Rating?
This terraced maisonette is located in LONDON, SE6 3BT. The property offers 101m² (1087 sq ft) of good-sized living space with 5 habitable rooms. It is a characterful interwar or early 20th century home. Currently rated G (14/100) for energy efficiency, this property would benefit significantly from energy improvements. With recommended improvements, it could achieve a C rating (75/100). 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 £2558, comprising £2174 for heating, £256 for hot water, and £128 for lighting. The property produces 9.9 tonnes of CO2 per year, which is high for a UK home.
