Raising your Energy Performance Certificate (EPC) rating doesn’t have to be confusing. Many homeowners and landlords try random upgrades and hope for the best—but the truth is, EPC improvements work best when approached strategically.

This blueprint breaks down step-by-step strategies to improve your EPC score efficiently and cost-effectively. If you need professional guidance or a full assessment, EPCrate can help:
👉 Book your EPC assessment

Step 1: Understand Your Current EPC

Before making any improvements, it’s essential to know your property’s starting point.

  • Check your current EPC report for weaknesses

  • Identify low-scoring areas like insulation, heating, or windows

  • Note which upgrades are most cost-effective

Professional assessors can provide this insight. Learn more about our process on the About Us page.

Step 2: Prioritise High-Impact Improvements

Some upgrades have a far greater effect on EPC scores:

  1. Loft Insulation – Top-up to recommended thickness (≥270mm)

  2. Wall Insulation – Cavity or solid wall options depending on property type

  3. Efficient Heating System – Modern boilers or heat pumps

  4. Hot Water Cylinder Insulation – Reduces energy loss

  5. Smart Heating Controls – Programmable thermostats and TRVs

Book a professional inspection to confirm which improvements are most suitable via our EPC Services.

Step 3: Add Renewable Energy Where Possible

Renewable energy can significantly boost your EPC:

  • Solar PV Panels – Reduce electricity demand, increase carbon rating

  • Solar Thermal Heating – Supports hot water efficiency

  • Air Source Heat Pumps – Excellent for well-insulated properties

Step 4: Implement Low-Cost, Quick Wins

While major upgrades are crucial, small changes also help:

  • LED lighting throughout the home

  • Draught-proofing windows, doors, and loft hatches

  • Radiator reflector panels

  • Sealing unused chimneys

These low-cost measures can improve your rating immediately and complement larger upgrades.

Step 5: Keep Documentation and Proof

Many EPC improvements require evidence:

  • Receipts for installation

  • Certifications for insulation or boilers

  • Details of renewable energy systems

Without proper documentation, assessors may assume the upgrades weren’t installed, limiting EPC gains.

Step 6: Schedule Your EPC Assessment Strategically

Timing matters:

  • Wait until all upgrades are complete before booking an EPC

  • Ensure any visible improvements are verifiable

  • Request a full assessment rather than a quick snapshot for accuracy

Book your next EPC via EPCrate’s Booking Page to guarantee a comprehensive evaluation.

Step 7: Monitor and Maintain Efficiency

After upgrades:

  • Service boilers and heating systems regularly

  • Replace bulbs with LEDs as needed

  • Keep insulation and draught-proofing in good condition

EPC ratings may degrade slightly over time if systems are neglected, so maintenance is key.

Step 8: Landlord & Compliance Considerations

For landlords, EPC compliance is not optional:

  • Properties must meet minimum EPC rating (Band E) to rent

  • Fines apply for non-compliance

  • Strategic upgrades help ensure legal compliance while improving tenant comfort

Final Thoughts

Following this step-by-step EPC blueprint ensures upgrades are effective, cost-efficient, and maximise your property’s rating. From insulation and heating improvements to renewable energy and quick wins, a strategic approach guarantees better results than random upgrades.
