About This Property
This terraced flat is located in ST. ALBANS, AL3 5RW. The property offers 43m² (463 sq ft) of compact living space with 2 habitable rooms. It is a post-war property from the mid-20th century. With an EPC rating of D (60/100), this property is around the UK average for energy efficiency. The pitched roof lacks adequate insulation.

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 £627, comprising £449 for heating, £113 for hot water, and £65 for lighting. The property produces 2.9 tonnes of CO2 per year, which is low for a UK home.
