Energy Performance Certificates (EPCs)

Understand your property’s energy efficiency and discover how to improve it.

An Energy Performance Certificate (EPC) provides a clear rating of how energy efficient your property is, along with recommendations to improve performance,
reduce running costs, and lower carbon emissions.

At Stron, we provide EPC assessments alongside practical guidance—helping you turn insights into real improvements.

An EPC rates a property’s energy efficiency on a scale from A (most efficient) to G (least efficient).

It includes:

  • Your current energy rating
  • Estimated energy costs
  • Environmental impact (CO₂ emissions)
  • Recommended improvements


EPCs are legally required when:

  • Selling a property
  • Renting a property
  • Building a new property

A good EPC rating isn’t just about compliance—it can have a real impact on your property.

Benefits include:

  • Lower energy bills
  • Improved comfort and insulation
  • Increased property value and appeal
  • Meeting minimum rental standards


For landlords, improving your EPC rating is becoming increasingly important as regulations continue to tighten.

Your EPC highlights practical ways to make your property more efficient.

Common recommendations include:

  • Installing solar PV systems
  • Upgrading to a heat pump
  • Improving insulation
  • Adding battery storage
  • Upgrading heating controls


At Stron, we go a step further by helping you understand which improvements will deliver the best return for your investment.

Unlike standard EPC providers, we don’t just hand over a certificate—we help you act on it.

Our team can:

  • Carry out your EPC assessment
