Why Does This Property Have a F Rating?
This semi-detached flat is located in WATFORD, WD18 0JP. The property offers 83m² (893 sq ft) of good-sized living space with 3 habitable rooms. It is a characterful interwar or early 20th century home. 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 (68/100). 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 £1690, comprising £1365 for heating, £205 for hot water, and £120 for lighting. The property produces 6.7 tonnes of CO2 per year, which is above average for a UK home.
