Why Does This Property Have a G Rating?

This terraced flat is located in LONDON, SW12 9RT. The property offers 48m² (517 sq ft) of compact living space with 2 habitable rooms. It is a characterful interwar or early 20th century home. Currently rated G (5/100) for energy efficiency, this property would benefit significantly from energy improvements. With recommended improvements, it could achieve a E rating (50/100). Underfloor heating provides even heat distribution and works particularly well with heat pumps due to the lower water temperatures required. 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 flat roof has poor insulation. Flat roof insulation is more complex but essential for preventing heat loss and condensation issues, typically costing £1,000-£3,000 depending on access and method. 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 £1916, comprising £1579 for heating, £266 for hot water, and £71 for lighting. The property produces 6.3 tonnes of CO2 per year, which is above average for a UK home. The property last sold in August 2025 for £485,000, with 3 recorded sales in our database.
