Your Energy Performance Certificate (EPC) rating doesn’t just reflect your property’s energy efficiency—it also directly affects your energy bills. Understanding this connection helps homeowners and landlords make informed decisions about improvements that save money and improve EPC ratings.

1. How EPC Ratings Relate to Energy Costs

  • EPCs measure energy efficiency and carbon emissions

  • Properties with high ratings (A–C) are cheaper to heat and power

  • Lower ratings (D–G) often indicate inefficient heating, poor insulation, and higher bills

Impact: A better EPC rating often translates into significant energy cost savings.

2. Factors Driving Energy Bills That EPCs Measure

a. Insulation

  • Poor loft, wall, or floor insulation leads to heat loss

  • Proper insulation reduces energy needed for heating

b. Heating Systems

  • Inefficient boilers, radiators, or heating controls increase consumption

  • Smart thermostats and TRVs optimise energy use

c. Windows and Doors

  • Single glazing or draughty doors increase energy demand

  • Energy-efficient glazing lowers heat loss and bills

d. Appliances and Lighting

  • Older, high-energy appliances and incandescent lighting raise electricity consumption

  • Energy-efficient alternatives reduce bills and improve EPC scores

3. Renewable Energy and Energy Bills

  • Solar PV, solar water heating, or heat pumps reduce reliance on grid electricity or gas

  • Excess energy from renewable sources can lower monthly energy costs

  • Renewable energy improvements also positively affect EPC ratings

4. Why EPC Scores Matter for Sellers and Landlords

  • Properties with higher EPC ratings are more attractive to buyers and tenants

  • Lower running costs can increase property value and rental appeal

  • Energy bills are often a key consideration in tenant and buyer decisions
