If you’re a homeowner in Suffolk, you’ve probably come across EPC ratings — especially if you’re looking to sell, rent, or upgrade your home. But can solar panels really impact your Energy Performance Certificate? The simple answer: yes — and here’s how.

What Is an EPC Rating?

EPC stands for Energy Performance Certificate. It’s a legal requirement when selling, renting, or building a property in the UK. Your EPC measures how energy-efficient your home is, with ratings from:

• A (Most efficient)
• down to G (Least efficient)

It assesses how much energy your property uses and wastes, and it includes tailored recommendations for improvement — such as better insulation, switching to low-energy lighting, or adding solar PV panels.

Why Your EPC Rating Matters

Improving your EPC isn’t just about ticking boxes — it brings real benefits:

• Boosts your property’s value
• Makes your home more appealing to buyers or tenants
• Highlights areas where you’re losing energy (and money)
• Opens up access to green finance and incentives

How Solar Panels Can Help

Solar PV systems are one of the most effective ways to improve your EPC rating. Here’s how they make a difference:
✅ Generate clean, renewable electricity
✅ Improve your EPC score by up to 15 points — often enough to move you up a full rating band
✅ Lower your energy bills by powering your home during daylight hours
✅ Reduce your carbon footprint and support sustainable living

If your current EPC already recommends solar, following that advice could instantly boost your rating and start saving you money.
