About This Property
This terraced maisonette is located in LONDON, NW2 7SR. The property offers 73m² (786 sq ft) of modest-sized living space with 3 habitable rooms. It is a post-war property from the mid-20th century. With an EPC rating of D (68/100), this property is around the UK average for energy efficiency. With recommended improvements, it could achieve a C rating (79/100). 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 loft insulation is rated very good, meeting or exceeding the recommended 270mm depth for optimal thermal performance. 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 £638, comprising £442 for heating, £123 for hot water, and £73 for lighting. The property produces 2.8 tonnes of CO2 per year, which is low for a UK home.
