Why Does This Property Have a G Rating?
This semi-detached flat is located in SOUTHEND-ON-SEA, SS1 2RF. The property offers 68m² (732 sq ft) of modest-sized living space with 3 habitable rooms. It is a characterful interwar or early 20th century home. Currently rated G (17/100) 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 £1838, comprising £1461 for heating, £291 for hot water, and £86 for lighting. The property produces 15.0 tonnes of CO2 per year, which is high for a UK home. The property last sold in June 2025 for £170,000, with 2 recorded sales in our database.
