About This Property

This semi-detached flat is located in COLCHESTER, CO1 1PG. The property offers 34m² (366 sq ft) of compact living space with 2 habitable rooms. It is a characterful interwar or early 20th century home. With an EPC rating of D (64/100), this property is around the UK average for energy efficiency.

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. Single glazing is a significant source of heat loss, accounting for up to 25% of a home's heat escaping through windows. Upgrading to double glazing typically costs £400-£600 per window but improves thermal comfort and can reduce noise by up to 30dB. Estimated annual energy costs are £661, comprising £479 for heating, £147 for hot water, and £35 for lighting. The property produces 3.2 tonnes of CO2 per year, which is low for a UK home.
