Why Does This Property Have a F Rating?
This terraced flat is located in MARLOW, SL7 1BE. The property offers 87m² (936 sq ft) of good-sized living space with 4 habitable rooms. It is a period property with Victorian or earlier origins. Currently rated F (34/100) for energy efficiency, this property would benefit significantly from energy improvements. With recommended improvements, it could achieve a D rating (65/100). The property uses electric storage heaters, which charge overnight on cheaper electricity tariffs. While having low installation costs, running costs are typically higher than gas central heating. A heat pump could reduce electricity use by 60-70%. 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. Estimated annual energy costs are £1498, comprising £1232 for heating, £193 for hot water, and £73 for lighting. The property produces 9.9 tonnes of CO2 per year, which is high for a UK home. The property last sold in October 2021 for £3,500,000, with 2 recorded sales in our database.
