An EPC (Energy Performance Certificate) is essential when selling, letting, or building a property in the UK. If your property scores poorly, it could lead to legal issues, financial penalties, or even lost sales and rentals. The good news? You can often boost your rating with just a few smart upgrades.

At EPCrate.co.uk, our certified London-based assessors help property owners pass their EPC inspections quickly and affordably—and we’re sharing our expert tips with you.

🧠 What Does an EPC Inspector Look For?

During an assessment, your EPC assessor evaluates:

  • 🧱 Wall, roof, and floor insulation

  • 🪟 Glazing quality (single, double, or triple)

  • 🔥 Heating systems and controls

  • 💡 Lighting type (LED vs. incandescent)

  • 🔌 Renewable technologies (solar panels, heat pumps)

  • 🛠️ Draught proofing, ventilation, and more

The result is an energy rating from A (most efficient) to G (least efficient).

✅ How to Pass Your EPC Inspection: Key Tips

1. Upgrade to LED Lighting

💡 Replace halogen or incandescent bulbs with LEDs. It’s fast, cheap, and makes a noticeable difference in your rating.

2. Insulate Your Loft and Walls

🏠 Proper insulation is one of the biggest rating boosters. Focus on:

  • 270mm+ loft insulation

  • Solid wall insulation (internal/external)

  • Cavity wall insulation (where applicable)

3. Seal Draughts

🚪 Use draught excluders around windows, doors, and skirting boards. Simple fixes can improve energy retention.

4. Install a Smart Thermostat or Heating Controls

🌡️ Controlling your heating more efficiently can push your score higher, especially if you have an older boiler.

5. Use Double or Triple Glazing

🪟 Upgrade old windows to double-glazed units for better heat retention.

6. Check Your Boiler Efficiency

🔥 Modern condensing boilers score better. If your boiler is old and inefficient, consider an upgrade—or at least fit thermostatic radiator valves (TRVs).

7. Provide Full Documentation

📂 If you’ve made improvements (like insulation or glazing), show evidence—receipts, specs, or installer certificates. This ensures the assessor can factor it into your score.

⚠️ Without proof, the assessor must assume the worst-case scenario.
