How to Read an EPC in 2025: What Your Energy Rating Really Means

Energy Performance Certificates (EPCs) are a legal requirement for all rented homes — but most people barely glance at them. In 2025, understanding your EPC rating can help you cut costs, improve comfort, and unlock access to energy grants. Here’s how to read and use your EPC like a pro.

What Is an EPC?

An EPC is a government-issued certificate that rates a home’s energy efficiency on a scale from A (most efficient) to G (least efficient). It also shows how costly a home is to heat and light — and includes recommendations to improve that score.

What’s On the EPC Page?

Current and potential energy rating (A–G scale)
Estimated energy costs per year
Recommended measures (e.g. insulation, double glazing)
Environmental impact score (CO2 emissions)

Why Does It Matter in 2025?

Energy prices remain high, and properties with poor EPC ratings cost significantly more to run. In fact, upgrading from an F to a C can cut annual bills by £700 or more. EPCs also determine access to government schemes like ECO4 or Boiler Upgrade Grants.

How to Improve Your EPC Rating

Add or improve insulation (roof, walls, floor)
Install low-energy lighting (LEDs)
Upgrade old boilers or heating systems
Seal drafts and replace single glazing

Can Tenants Take Action?

Yes. While landlords are responsible for major improvements, tenants can request EPC reports, push for basic upgrades, and access support via Property Krowd. We provide EPC check tools and highlight red flags in rental ads so you know what you’re walking into.
