An EPC (Energy Performance Certificate) is a legal requirement when you sell or let a property in Hounslow. It rates your home's energy efficiency on a scale from A (most efficient) to G (least efficient), and provides recommendations for improvements. You'll need one before marketing your property, whether it's a house, flat or other dwelling.

The average EPC rating in Hounslow is D. However, around 60% of properties in the area fall below EPC rating C, which means many homes have room for energy efficiency improvements. If your property is rated D or lower, you may want to consider upgrades to improve its rating and appeal to potential buyers or tenants.

An EPC certificate is valid for 10 years from the date it's issued. If you're selling or letting your property, you'll need a current certificate. If your certificate is expiring soon, you'll need to arrange a new assessment before marketing your home.

Since many properties in Hounslow date from the mid-20th century, they often lack modern insulation. The most commonly recommended improvement is loft insulation, which is cost-effective and can significantly reduce heat loss. Other typical recommendations include cavity wall insulation, boiler upgrades, and improved heating controls. These improvements can help lower your energy bills and increase your property's rating.

A lower EPC rating may make your property less attractive to buyers and tenants, particularly as more people prioritise energy efficiency and running costs. With 60% of Hounslow properties below rating C, improving your EPC rating through recommended upgrades like loft insulation could give you a competitive advantage. Even if you don't make improvements, you must still provide an accurate EPC certificate when selling or letting.
