When it comes to Energy Performance Certificates (EPCs), many homeowners focus on walls, roofs, and heating systems—but flooring can also impact energy efficiency. The right flooring choices can reduce heat loss, improve insulation, and even help boost your EPC rating.

Learn more about our professional EPC services on our About Us page.

1. The Role of Flooring in Energy Efficiency

Floors are a major source of heat loss, particularly in older properties. Key factors include:

  • Floor type (solid, suspended, or raised)

  • Insulation beneath or within flooring

  • Materials used for flooring (wood, laminate, carpet, tile)

Properly insulated floors reduce energy consumption and contribute to higher EPC scores.

2. Flooring Types and Their Impact

Carpeted Floors

  • Provides natural insulation

  • Reduces heat loss through floorboards

  • Soft surface improves comfort

Impact: Generally positive for EPC ratings when combined with underlay and insulation.

Wood or Laminate Flooring

  • Moderate insulation value

  • Can be combined with insulated underlay for energy efficiency

  • Sealing gaps between boards reduces draughts

Impact: With correct installation and insulation, EPC impact is neutral to positive.

Tiled or Stone Floors

  • Poor natural insulation

  • Can lead to higher heat loss if not paired with underfloor heating or insulation

  • Requires additional energy to heat

Impact: Potentially lowers EPC scores unless paired with underfloor heating and proper insulation.

3. Suspended Floors in Older Homes

  • Air gaps beneath suspended floors can increase heat loss

  • Insulating beneath floorboards is essential

  • Draught-proofing edges can prevent cold spots

Impact: Addressing these issues improves energy efficiency and EPC rating.

4. Upgrades That Improve EPC Scores

  • Install floor insulation in lofts, ground floors, and extensions

  • Use energy-efficient underlay with laminate or wood floors

  • Consider underfloor heating systems in tile or stone areas

  • Seal gaps and remove draughts around floor edges
