Existing Dwelling EPC
Providing clear, reliable assessments and practical energy-saving recommendations
What is EPC & Why Do You Need One?
An Energy Performance Certificate (EPC) is an assessment that shows how energy efficient your existing home is, rated from A to G. For existing dwellings, an EPC is based on a visual inspection of the property’s insulation, heating system, windows, and overall construction to understand how much energy the home uses and where improvements can be made.
You’ll need an EPC when selling or renting your property, and it’s often required for accessing grants or funding aimed at improving energy efficiency. Beyond compliance, an Existing Dwelling EPC gives you clear, practical insights into how to reduce running costs, make your home warmer, and increase its long-term value.
Understanding the Purpose and Requirements of an EPC
An Energy Performance Certificate provides a clear breakdown of how efficiently a property uses energy, its environmental impact, and where improvements can be made. For existing homes, the EPC outlines estimated energy use, potential savings, and tailored recommendations to help homeowners reduce running costs and improve overall performance. The assessment is based on ‘standard occupancy’ assumptions, which means the rating reflects a consistent benchmark rather than the unique way each household may use heating, lighting, or appliances.
You’ll need an EPC whenever a property is marketed for sale or rent in the UK, and it must be available to potential buyers or tenants from the outset. An EPC remains valid for up to ten years unless a newer assessment is carried out. Whether you're preparing to sell, let, or simply understand how your home performs, an up-to-date EPC ensures you meet legal requirements while gaining valuable insight into your property’s energy efficiency.
