2. Heating System Upgrades

Heating systems are often the largest factor affecting EPC ratings:

  • Consider renewable heating systems like heat pumps

These upgrades can raise your EPC band significantly:

3. Insulation Improvements

Proper insulation prevents heat loss and boosts EPC scores:

  • Loft insulation to recommended depth

  • Cavity wall insulation if not already installed

  • Floor insulation for suspended floors

  • Pipe and cylinder insulation

Documenting these improvements ensures they are credited during assessment:

Windows and doors influence heat retention:

  • Upgrade to double or triple glazing

  • Seal gaps with draught-proofing

  • Install thermal curtains or secondary glazing for cost-effective improvements

Even minor changes can significantly improve energy efficiency.

5. Lighting and Renewable Solutions

Energy-efficient lighting and renewable energy options can boost EPC:

  • Switch to LED lighting throughout the home

  • Consider solar PV panels or solar water heating

  • Use energy monitoring devices to optimise usage

These improvements are particularly impactful for properties with very low starting EPCs:
