An EPC (Energy Performance Certificate) is a legal requirement when you sell or let a property in Gloucester. It rates your home's energy efficiency on a scale from A (most efficient) to G (least efficient). The certificate shows potential buyers or tenants how much it will cost to heat and light your property, and suggests improvements you could make. In Gloucester, the average rating is D, so many properties fall below the more desirable C rating.

Gloucester has a high proportion of mid-20th century properties, which tend to have older heating systems, single-glazed windows, and poor insulation. Around 60% of properties in the area are rated below EPC C. These older homes were built before modern energy efficiency standards came into force, which is why many homeowners are now investing in improvements to boost their ratings and reduce energy bills.

Loft insulation is the most recommended improvement for properties in Gloucester. It's one of the quickest and most cost-effective ways to improve your EPC rating, reduce heat loss, and lower your energy bills. Many mid-20th century houses in the area have inadequate loft insulation, making this a priority upgrade that can move you from a D to a C rating.

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

From April 2020, landlords in England cannot let a property with an EPC rating below E. In Gloucester, where many houses are rated D or lower, this means some older properties may need improvements before they can be legally let. Loft insulation, cavity wall insulation, and boiler upgrades are common improvements landlords make to meet this minimum standard.
