Energy Performance Certificates (EPCs) provide a clear indication of a property’s energy efficiency, but many homeowners, landlords, and buyers are unclear about what the ratings actually mean. Understanding EPC bands is crucial for legal compliance, energy savings, and property value.

Learn more about our accredited services on our About Us page.

What Are EPC Bands?

EPCs use a scale from A to G to indicate energy efficiency:

  • A (92–100): Most efficient

  • B (81–91): Very good

  • C (69–80): Above average, common in modern homes

  • D (55–68): Average, legal minimum for many rentals

  • E (39–54): Below average, may require improvements

  • F (21–38): Poor, significant upgrades needed

  • G (1–20): Least efficient, urgent improvements required

Your EPC band reflects heat loss, insulation, heating systems, and renewable energy use.

Why EPC Bands Matter

  1. Legal Compliance

    • For landlords, a minimum EPC rating (usually E) is required to rent properties.

    • Failing to comply can result in fines up to £5,000 per property.

  2. Energy Bills

    • Higher-rated homes (A–C) consume less energy for heating and cooling.

    • Lower-rated properties (E–G) are costly to heat and less comfortable.

  3. Property Value and Marketability

    • Homes with better EPC ratings are more attractive to buyers and tenants.

    • Improved EPC scores can increase resale value and reduce void periods.

Factors That Influence Your EPC Band

  • Insulation: Loft, walls, and floors

  • Heating system efficiency: Boilers, thermostats, TRVs

  • Windows and doors: Glazing and draught-proofing

  • Renewable energy: Solar panels, heat pumps, or battery storage

  • Ventilation and thermal bridges: Proper sealing and air flow

A certified EPC assessor can identify the factors that affect your band and recommend improvements.

Improving Your EPC Band

  1. Upgrade Insulation: Loft, walls, floors, or extensions

  2. Modernise Heating: Install energy-efficient boilers or smart controls

  3. Improve Glazing: Double or triple glazing with Low-E glass

  4. Consider Renewables: Solar panels or heat pumps

  5. Seal Draughts: Doors, windows, and loft hatches
