EPC Assessors in London
EPC stats for London
An Energy Performance Certificate (EPC) is a legal requirement when you sell or let a property in London. It shows how energy efficient your home is, rated from A (most efficient) to G (least efficient). You'll need a qualified assessor to produce one, and we've listed 1,368 active assessors across the capital to help you find someone local.
The average London property rates at band D for energy efficiency. This reflects the age of much of the housing stock – most homes here were built in the mid-20th century, when building standards were very different from today. Around 60% of London properties fall below band C, meaning there's significant room for improvement in how efficiently many homes use energy.
Houses make up the majority of London's residential properties, though you'll also find plenty of flats and converted period buildings. Whatever your property type, an EPC assessment takes around an hour and covers things like insulation, heating systems, windows and ventilation.
The most commonly recommended improvement across London is loft insulation. It's straightforward to install, relatively affordable, and can make a real difference to your heating bills and comfort. Many assessors will flag this during their survey if your loft lacks adequate insulation.
Whether you're selling, letting, or simply curious about your home's energy efficiency, finding a local assessor is straightforward. Use our directory to compare qualified professionals in your area and book an assessment that suits your schedule.

Frequently asked questions
An EPC (Energy Performance Certificate) is a legal document that rates your property's energy efficiency on a scale from A (most efficient) to G (least efficient). In London, you're required by law to have a valid EPC when selling or letting a property. It shows potential buyers or tenants how much energy your home uses and what it might cost to heat and power it. The certificate is valid for 10 years.
The average EPC rating for London properties is D, with around 60% of homes currently rated below EPC C. If your property has a D rating, you're in line with the London average. However, if you're looking to improve your home's appeal to buyers or tenants, or reduce energy bills, aiming for a C rating or higher is increasingly important, especially as energy efficiency standards continue to tighten.
Older properties, particularly those from the mid-20th century which are common across London, typically have lower EPC ratings because they often lack modern insulation, have older heating systems, and feature single-glazed windows. These homes were built before current energy efficiency standards existed. The good news is that improvements like loft insulation—the most recommended upgrade for London properties—can significantly boost your rating without major expense or disruption.
Loft insulation is the most recommended improvement for London properties and offers excellent value for money. It's relatively affordable to install, requires minimal disruption, and can improve your EPC rating noticeably. Other cost-effective measures include draught-proofing, upgrading to a modern boiler, and installing double-glazed windows. These improvements not only boost your EPC rating but also reduce energy bills, making them attractive to potential buyers or tenants.
Yes, increasingly so. While an EPC rating alone doesn't determine value, properties with better ratings (B or C) are becoming more attractive to London buyers and tenants who are conscious of energy costs and environmental impact. Properties with lower ratings may take longer to sell or let, and landlords should note that from April 2025, lettings will require a minimum EPC rating of E. Improving your rating now can enhance your property's marketability and rental potential.
