An EPC (Energy Performance Certificate) is a legal requirement when you sell or let a property in Wandsworth. 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 any other type of building.

The average EPC rating in Wandsworth is D. However, around 60% of properties in the area fall below EPC rating C, which means there's significant potential for energy efficiency improvements across the borough. If your property is rated D or lower, you may want to consider upgrades to improve its rating and appeal to buyers or tenants.

Loft insulation is the most commonly recommended improvement for properties in Wandsworth, particularly for older houses from the mid-20th century. This is one of the most cost-effective upgrades you can make, as it reduces heat loss significantly and often qualifies for government grants. Other improvements might include cavity wall insulation, upgrading heating systems, or improving window efficiency.

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.

Yes, and it's often worthwhile. Making energy efficiency improvements can increase your property's appeal and value. Starting with loft insulation is a popular choice in Wandsworth, as it's relatively affordable and delivers noticeable improvements. Other upgrades like better heating systems or insulation can also boost your rating. A new EPC assessment will reflect these improvements.
